Is there a pin-compatible replacement for M254D-02-060-B?

Yes, several headers like the Megastar ZX-HA series are pin-compatible in terms of form factor (2-pin, 2.54mm pitch, straight). However, they are not electrically equivalent and present a downgrade risk.

What risks should I check before replacing M254D-02-060-B?

Key risks include lower current rating (e.g., 2A vs 3A), lower voltage rating (e.g., 250V vs 1000V), a narrower operating temperature range, and different contact plating (tin vs. gold), which can affect reliability.

M254D-02-060-B Alternatives, Datasheet & Cross Reference | DEALON

Finding a substitute for the DEALON M254D-02-060-B 2.54mm header requires checking key electrical and environmental specs. While several 2-pin headers share the same form factor, most have lower voltage, temperature, or current ratings.

AI replacement insight

Electrical riskhigh

Candidates have much lower voltage ratings; some also have lower current ratings.

Package risklow

Form factor (2.54mm straight header) is standard and widely available.

Sourcing risklow

Many manufacturers produce similar headers, though specs vary.

Can it be replaced directly?

No direct, fully equivalent replacement has been identified. All potential substitutes require careful review of parametric downgrades.

Best replacement path

The Megastar ZX-HA series (e.g., ZX-HA2.54-2PZZ-R) if the application can tolerate lower voltage/temperature ratings and tin plating.

Main risk

Electrical and environmental stress. Most alternatives have significantly lower voltage ratings, narrower temperature ranges, and tin instead of gold plating.

Recommended alternatives

Matches form factor and current, but has lower voltage, different plating, and missing temperature specs.
