XUNPU
A 50 Ohm SMT RF connector with matching electrical specs and a footprint that appears compatible with the target's MHF4 type.
KH-IPEX4-2020 is a surface-mount MHF4-type RF connector from Kinghelm, rated for 50 Ohms and frequencies up to 6 GHz. When seeking alternatives, focus on MHF4-compatible connectors with identical footprints and electrical ratings.
Footprint and height must be verified from datasheets to ensure fit.
Key parameters like impedance and frequency are common and easy to match.
A direct drop-in replacement is likely available, but requires careful comparison of mechanical drawings. No candidate can be confirmed as a direct replacement without this engineering check.
Focus on candidates explicitly listed as MHF4 compatible, such as XUNPU IPEX-004. Verify the PCB footprint and height from the datasheet.
The primary risk is mechanical incompatibility. While many connectors are 'IPEX compatible,' they belong to different series (MHF1, MHF3, MHF4) with non-interchangeable footprints and mating heights.

| Feature / factor | KH-IPEX4-2020 | IPEX-004 | IPEX-001 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Connector Series | IPEX MHF4 | IPEX (MHF4 implied) | IPEX (generic) | IPEX (MHF4 implied) / IPEX (generic) — Candidate P/N and datasheet drawing strongly suggest MHF4 compatibility.; IPEX-001: Datasheet drawing suggests MHF4 compatibility, but part number is generic. | |
| Package | SMT | SMT | SMT | SMT — Datasheet shows a 2.0x2.0mm footprint, appearing to match the MHF4 standard.; IPEX-001: Datasheet shows a 2.0x2.0mm footprint, appearing to match the MHF4 standard. | |
| Impedance | 50 Ohm | 50 Ohm | 50 Ohm | 50 Ohm — matched; IPEX-001: matched | |
| Frequency | DC to 6 GHz | DC ~ 6GHz | DC ~ 6 GHz | DC ~ 6GHz / DC ~ 6 GHz — matched; IPEX-001: matched | |
| Voltage | 60 V AC | 60V AC | - | 60V AC — matched |
The best alternatives for KH-IPEX4-2020 are other MHF4-compatible RF connectors with a 50 Ohm impedance and a DC-6GHz frequency range. Parts like XUNPU's IPEX-004 show strong parametric and mechanical similarity, but require datasheet verification.
