Is there a pin-compatible replacement for PH-01291?

HC-JN254-2-03-Z is a potential pin-compatible replacement, but this requires verification of mechanical drawings in both datasheets. 321006SG0ABK00A01 has a compatible pinout but includes a shroud, making it a form-fit but not identical replacement.

What risks should I check before replacing PH-01291?

First, verify the mechanical footprint; ensure the number of rows (2), pitch (2.54mm), and pin arrangement (2x3) match. Second, check for shrouds on the replacement which may interfere with other components. Finally, confirm electrical ratings like voltage (1000V) and current (3A) are met or exceeded.

PH-01291 Alternatives, Datasheet & Cross Reference | Shenzhen Liansheng Precision Connector Co., Ltd.

PH-01291 is a standard 2.54mm pitch, 2x3 (6-pin) male pin header for through-hole applications. Key alternatives must match its 3A/1000V rating and physical footprint.

AI replacement insight

Package riskmedium

Alternatives may have shrouds or different dimensions requiring layout verification.

Electrical risklow

Several candidates match the voltage and current ratings.

Can it be replaced directly?

No drop-in replacement has been verified. HC-JN254-2-03-Z is a likely candidate that requires a quick datasheet check to confirm it is pin-compatible.

Best replacement path

HC-JN254-2-03-Z is the strongest candidate, matching all key specs, but requires pinout verification. 321006SG0ABK00A01 is electrically compatible but its shrouded package requires checking board clearance.

Main risk

The main risk is mechanical incompatibility. Some alternatives are shrouded (box headers) which may not fit on a board designed for an unshrouded header.

Recommended alternatives

A 6-pin header with matching electrical ratings, but features a shroud which requires board layout verification.
