Is there a pin-compatible replacement for KH-SMA-KE-Z?

No direct pin-for-pin compatible replacement has been identified in this review. All suitable functional alternatives have different pin counts or footprints, requiring PCB layout verification.

What risks should I check before replacing KH-SMA-KE-Z?

The primary risk is mechanical incompatibility. You must verify the candidate's PCB footprint (pin count, spacing, and arrangement) against your board layout. A board redesign is likely necessary.

KH-SMA-KE-Z Alternatives, Datasheet & Cross Reference | Guangdong Hongzhi Electronics Technology Co., Ltd.

KH-SMA-KE-Z is a 5-pin straight PCB-mount SMA female connector. While functional alternatives exist, they typically differ in pin count and PCB footprint, requiring layout verification and likely a board redesign for substitution.

AI replacement insight

Package riskhigh

Candidates have 4 pins while the target has 5, requiring a board redesign.

Electrical risklow

Candidates offer similar RF performance (impedance, frequency range).

Sourcing risklow

Multiple vendors offer SMA connectors with similar specs but varying footprints.

Can it be replaced directly?

No, a direct pin-compatible replacement for KH-SMA-KE-Z has not been identified. All potential alternatives require verifying a different PCB footprint.

Best replacement path

KH-SMA-K513-13G is the closest functional match from the same manufacturer, but it is not a drop-in replacement.

Main risk

The primary risk is mechanical incompatibility due to a different PCB footprint (pin count and layout).

Recommended alternatives

A functional alternative with a different 4-pin footprint; requires board layout review.
