Substitute Part Grouping Explanation

Substitution of the OSTHM039080 is based on electrical and mechanical parameter equivalence. The primary substitute HM0390800000G from Amphenol Anytek maintains identical specifications across all critical parameters: 3-position configuration, 7.5mm pitch, 8A current rating, 250V voltage rating, 12-28 AWG wire gauge compatibility, through-hole mounting, and screwless push-in spring termination. Both components feature thermoplastic housings with brass contacts and interlocking side features. The substitute part meets the same RoHS3 compliance and REACH unaffected status as the original component.

Parameter Comparison

Engineering Selection Recommendations

The HM0390800000G from Amphenol Anytek is the direct equivalent substitute for the obsolete OSTHM039080. Both components satisfy identical electrical and mechanical requirements for 3-position, 7.5mm pitch terminal block applications. The substitute part carries active product status, ensuring continued availability and supply chain reliability. Both components maintain ROHS3 compliance and REACH unaffected certification, meeting regulatory requirements for industrial and commercial applications. The Amphenol Anytek substitute provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), offering improved thermal performance margins. Tin plating on the brass contacts of the substitute part enhances corrosion resistance compared to unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM0390800000G be used as a direct replacement for OSTHM039080 in existing designs?

A: Yes. Both components share identical electrical ratings (8A, 250V), mechanical configuration (3-position, 7.5mm pitch), mounting type (through-hole), and wire termination method (screwless push-in spring). PCB footprints and wire gauge compatibility (12-28 AWG) are equivalent.

Q: What is the difference in contact plating between the two parts?

A: The OSTHM039080 features unplated brass contacts, while the HM0390800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments.

Q: Are there temperature rating differences that affect application suitability?

A: The HM0390800000G operates across a wider temperature range (-40°C to 115°C) compared to the OSTHM039080 (-30°C to 105°C). For applications within the original part's temperature limits, both components perform equivalently. For extended temperature applications, the substitute offers superior thermal margins.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the OSTHM039080 and HM0390800000G are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial use.

Q: What is the inventory status for each part?

A: The OSTHM039080 has 1008 pieces in stock as new original inventory. The HM0390800000G substitute has 712 pieces available as new original inventory in bulk packaging.
