Frequently Asked Questions (FAQ)

Q: Can HM2170800000G be used as a direct replacement for OSTHM217080 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (5.00mm), position count (21), mounting type (through-hole), and electrical ratings (8A, 250V). PCB footprints and wire termination methods are equivalent, enabling direct substitution without design modification.

Q: What is the significance of the tin plating on the HM2170800000G contacts?

A: Tin plating on brass contacts provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments compared to unplated brass. This represents a material enhancement in the substitute part.

Q: Are there any temperature-related limitations when substituting these components?

A: The HM2170800000G operates across a wider temperature range (-40°C to 115°C) compared to the OSTHM217080 (-30°C to 105°C). For applications within the original part's temperature specification, both components perform equivalently. For applications requiring extended temperature operation, the substitute part provides additional margin.

Q: Do both components support the same wire gauge range?

A: Yes. Both the OSTHM217080 and HM2170800000G accommodate 12-28 AWG wire gauges with identical screwless push-in spring termination, ensuring compatibility with existing wire harness specifications.

Q: What is the packaging difference between these components?

A: The OSTHM217080 is listed with unspecified packaging, while HM2170800000G is supplied in bulk packaging. Verify packaging requirements with your procurement specifications for order fulfillment.
