Is there a pin-compatible replacement for KH-SMA-K513-G?

While 5-1814832-2 from TE Connectivity is a form-fit-function match, pin-to-pin compatibility requires a detailed comparison of the PCB layout and datasheet drawings. Direct drop-in replacement is not guaranteed without this check.

What risks should I check before replacing KH-SMA-K513-G?

The primary risk is mechanical. Verify the PCB footprint (pin locations, diameters, and keep-outs) of any alternative. Also confirm that the RF performance, particularly VSWR, meets your application's requirements across its operating frequency.

KH-SMA-K513-G Alternatives, Datasheet & Cross Reference | Guangdong Hongzhi Electronics Technology Co., Ltd.

KH-SMA-K513-G is a 50 Ohm, right-angle, through-hole SMA jack for RF applications up to 6 GHz. Finding a substitute requires matching the connector type, impedance, frequency range, and PCB footprint.

AI replacement insight

Package risklow

The connector style matches, but the exact footprint dimensions for the mounting pins must be verified.

Electrical risklow

All key electrical parameters (impedance, frequency, voltage) match or exceed the target's specifications.

Can it be replaced directly?

No direct, verified pin-to-pin replacement has been identified. The candidate 5-1814832-2 is a strong form, fit, and function match that requires user verification of the PCB layout.

Best replacement path

Evaluate 5-1814832-2 from TE Connectivity, which matches on all key parameters but requires a final mechanical footprint check.

Main risk

Mechanical incompatibility due to subtle differences in the PCB footprint.

Recommended alternatives
