Engineering Selection Recommendations

The Molex 0877582016 serves as the direct manufacturer equivalent to the obsolete 0870892016. Both parts share identical electrical and mechanical specifications within the Molex Milli-Grid product line. The 0877582016 maintains active product status and is available in higher inventory quantities. This part is suitable for direct replacement in existing designs without modification.

The Samtec TMM-110-03-G-D represents a cross-manufacturer alternative that maintains all critical mating and mounting parameters. This part differs in insulation material composition (Liquid Crystal Polymer versus Polyamide) and contact post finish (Gold versus Tin-Lead). The Samtec part provides ROHS3 compliance and specified operating temperature range (-55°C ~ 125°C) with rated current capacity (3.2A per contact), offering enhanced environmental and thermal specifications compared to the original part.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, addressing regulatory requirements that the original obsolete part does not meet.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0877582016 be used as a direct replacement for the 0870892016?

A: Yes. The 0877582016 maintains identical pitch (2.00mm), position count (20), row configuration (2), contact type (male pin), mounting method (through hole), and fastening mechanism (push-pull). Both parts are from the Molex Milli-Grid series and are mechanically and electrically interchangeable.

Q: What are the key differences between the Molex 0877582016 and Samtec TMM-110-03-G-D?

A: The primary differences are insulation material (Polyamide PA46 versus Liquid Crystal Polymer), contact post finish (Tin versus Gold), and specified operating temperature range. The Samtec part provides rated current capacity (3.2A per contact) and operating temperature specification (-55°C ~ 125°C), while the Molex part does not specify these parameters. Both maintain identical mating pitch, position count, and row spacing.

Q: Are there packaging differences between substitute parts?

A: The Molex 0877582016 is supplied in Tray packaging, while the Samtec TMM-110-03-G-D is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For direct replacement of existing designs, the Molex 0877582016 is recommended due to series continuity and identical specifications. For applications requiring specified operating temperature range or rated current capacity, the Samtec TMM-110-03-G-D provides these parameters.

Q: Do all substitute parts meet current regulatory requirements?

A: The Molex 0877582016 and Samtec TMM-110-03-G-D both carry ROHS3 compliance and REACH unaffected status. The original 0870892016 is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulations.
