A 2.54mm pitch, 2-pin straight header with gold plating, matching key form, fit, and material specifications.
Best Alternatives to 826629-2
Finding a replacement for the TE Connectivity 826629-2, a 2-pin 2.54mm pitch header, involves matching the pitch, pin count, straight through-hole mounting, and gold plating. Several functional alternatives exist with similar form factors.
AI replacement insight
Electrical riskmedium
Mismatched plating (Tin vs. Gold) can cause fretting corrosion and connection failure.
Package risklow
Many alternatives match the form factor, but mechanical drawings must be checked.
Can it be replaced directly?
While no official drop-in replacement is listed, several manufacturers produce headers with identical form, fit, and function. HCTL PZ254-1-02-Z-8.5 is a strong candidate requiring datasheet verification.
Best replacement path
The most promising path is sourcing a generic 2.54mm 2-pin straight header with gold-plated contacts, like HCTL PZ254-1-02-Z-8.5.
Main risk
The main risk is substituting with a tin-plated or physically different connector type (e.g., XH series), which can lead to connection failure or mechanical interference.
