Pulse Electronics Cross Reference to VOOHU Parts
Pulse Electronics LAN transformers such as H1102NL, RJ45 jacks with magnetics and SFP cages mapped to VOOHU functional alternatives, each with a report.
This page maps Pulse Electronics part numbers to VOOHU parts: LAN transformers, RJ45 jacks with integrated magnetics, SFP cages and BMS isolation transformers. Every row is a functional alternative — verify with samples in your design — and links to a comparison report that sets the two datasheets side by side. We write pin-to-pin or drop-in only for a specific pair that our FAE team has confirmed in writing, and that row shows the date of the confirmation. For every other pair, plan to check the footprint, height and test conditions listed below before you change the BOM. If your Pulse part number is not in the table, send it through our sample request form. Samples are available for evaluation, and selected parts are free of charge. Our FAE team will be glad to confirm the options for your project.

What to check before you switch from a Pulse part
The points below come from the Pulse comparison reports linked in the table. They are the differences that come up most often between the two datasheets; the report for your pair has the exact values.
LAN transformers
- Body height. In several reports the VOOHU body is taller: H5004NL and H5007NL are 5.72 mm (Pulse) against 6.00 mm (VOOHU), H5008NL 5.87 mm against 6.10 mm, and on the low-profile parts H5120NL is 2.08 mm max against 2.50 mm max and HX5120NL 2.08 mm max against 2.85 mm max. For H1164NL, Pulse gives 5.84 mm max and VOOHU 5.70 ± 0.50 mm. If the transformer sits under a shield can, a heat sink or a card edge, check the clearance against the VOOHU maximum, not the nominal value.
- Land pattern. Pin count and pitch match, but the recommended pads do not always: for H1164NL the outer pad span is 16.76 mm (Pulse) against 17.00 mm (VOOHU) and the pad width 1.02 mm against 0.76 mm. Overlay both land patterns before you reuse a Pulse footprint, and ask your EMS to look for bridging and side fillets on the first build.
- Turns-ratio tolerance. Where Pulse states a tolerance it is ±2% (for example HX1188NL, H5008NL, H5120NL), while the VOOHU LAN transformers in these reports are specified 1CT:1CT ±5%. Check the magnetics requirement in your PHY datasheet.
- Test conditions. Both sides usually list OCL as 350 µH min at 100 kHz, but the test voltage and DC bias are written differently, and Pulse often gives insertion loss as a formula up to 125 MHz where VOOHU lists −1.1 dB max from 1 to 100 MHz (H5008NL, H5120NL, HX5120NL). Write your incoming inspection from the VOOHU datasheet rather than reusing the Pulse limits. For the 10GBASE-T pair H7008NL, the report lists OCL 200 µH min (Pulse) and 120 µH min (VOOHU) at 100 kHz, so compare both with the OCL your 10G PHY asks for.
- Moisture sensitivity. Pulse lists H1164NL as MSL 4; the VOOHU datasheet does not state an MSL. Ask us for the MSL and packing details before the parts go onto a line that manages moisture-sensitive devices.
RJ45 jacks with integrated magnetics
- Hi-pot test time. In the J0011D01BNL, J0011D21BNL, JX0011D21BNL and JX0011D21NL reports, Pulse specifies isolation at 1500 Vrms (for JX0011D21NL, 60 Hz for 1 minute), and the VOOHU datasheets state 1500 V AC and 2250 V DC for 6 s at 1 mA. If your safety file or incoming test quotes a one-minute test, settle the test condition with us before release.
- Typical values against limits. In the J0011D01BNL, J0011D21BNL, JX0011D21BNL and JX0011D21NL reports, several Pulse electrical values are typical, while VOOHU gives minimum or maximum limits. A typical value and a guaranteed limit cannot be compared directly; check each one against your PHY's requirement.
- Mechanics and temperature. The same four reports list mating force as 5 lbs (about 22.2 N) max on the Pulse side and 23 N max on the VOOHU side. J0011D01BNL and J0011D21BNL are 0 to +70 °C parts; the VOOHU parts listed for them are rated −40 to +85 °C. For JXD3-0002NL the outline and panel cut-out values are the same in both datasheets, but the contact gold is 30 µin selective (Pulse) against 6 µin on the contact area (VOOHU); if your drawing sets a plating thickness, that line decides.
SFP cages
- Cage material. Pulse lists copper alloy. For SFPPCAGE011-L and for SFPCAGE002-L against WH191R02SD0S02, the VOOHU cage is nickel-plated stainless steel; WH81-111-Y0002-1 is copper alloy like the Pulse part. If your mechanical drawing or EMC plan names the cage material, the change has to go through that review.
- Dimensions. Pulse gives several cage dimensions as reference (REF) values. In the SFPPCAGE011-L report the VOOHU drawing gives them with tolerances (front width 14.00 against 14.00 ± 0.10 mm); for SFPCAGE002-L against WH81-111-Y0002-1, the length is 48.80 REF against 48.70 mm and the height 9.47 REF against 9.45 mm. Check the bezel opening and the PCB cut-out against the VOOHU drawing.
Rows marked "Comparison only — see report" (HXB6014HLT, HM1238NLT, JXD3-0002NL, SFPPCAGE011-L) are assessments, not functional alternatives; read the report before you plan around them. For any pair, our FAE team can suggest suitable parts and help check the design, including an overlay of the two footprints.

FAQ
Q1Is each VOOHU part an exact alternative to the Pulse part, with the same footprint?
Only if the row says that our FAE team has confirmed the pair in writing. Every other row is a functional alternative — verify with samples in your design. The reports often show the same pin count and pitch with a different body height, pad size or test condition; for H1164NL, for example, the recommended outer pad span is 16.76 mm on the Pulse drawing and 17.00 mm on the VOOHU drawing. Overlay the two footprints before you reuse a board.
Q2Is H1102NLT the same part as H1102NL?
In the Pulse part numbers quoted in our reports, a trailing T marks tape-and-reel packing — the H1102NL report, for example, reads "H1102NL (Tape & Reel: H1102NLT)" — so H1102NLT and H1102NL are the same transformer packed differently. The table lists the base number, and the VOOHU part shown applies to both. Reel quantities can differ: for H5004NL, Pulse lists 300 pcs per reel and VOOHU lists 350 pcs per reel for the WHSG24701G, so update your ordering multiples.
Q3How do I compare a Pulse datasheet with a VOOHU datasheet when the test conditions differ?
Compare each datasheet with your PHY's magnetics requirement rather than with each other. Pulse often gives insertion loss as a formula up to 125 MHz and some RJ45 values as typical, while VOOHU lists maximum or minimum limits, usually from 1 to 100 MHz. Write your incoming inspection from the VOOHU datasheet's own conditions — test voltage, DC bias and duration — and ask our FAE team to confirm any line your design depends on.
