Needs validationlow risk
A 7-pin, 2.0mm pitch header from JST's PH series with matching electrical ratings; likely form-fit compatible.
Best Alternatives to PH-7A
The PH-7A is a common 7-pin, 2.0mm pitch single-row header for wire-to-board connections. While many alternatives exist, careful verification of mechanical dimensions is crucial for finding a successful drop-in replacement.
AI replacement insight
Electrical risklow
Many alternatives match or exceed the 100V/2A rating.
Package riskmedium
Requires datasheet review to confirm PCB footprint and mating compatibility.
Sourcing risklow
The 2.0mm pitch 7-pin header is a common form factor with many suppliers.
Can it be replaced directly?
Direct replacement for PH-7A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use a JST PH series connector like B7B-PH-K-S(LF)(SN), which matches all key electrical specs and is from the original manufacturer series.
Main risk
The primary risk is mechanical incompatibility. Even with the same pin count and pitch, the plastic shroud dimensions, pin length, and PCB footprint can vary slightly between manufacturers.
