Engineering Selection Recommendations

Primary Recommendation: Molex 0877604017

The Molex 0877604017 from the Milli-Grid 87760 series provides the closest functional equivalence to the 86453-140LF. This part maintains all 40 positions fully loaded and shares identical mating pitch, row spacing, contact configuration, and finish specifications. The part is in active production status with ROHS3 compliance certification, ensuring long-term supply availability and regulatory alignment. The Milli-Grid 87760 series is widely adopted in telecommunications and general-purpose applications, providing established design validation across multiple platforms.

Secondary Recommendation: Samtec TMM-120-01-F-D-RA

The Samtec TMM-120-01-F-D-RA from the TMM series offers full 40-position loading with identical electrical interface specifications. This connector features an extended operating temperature range (-55°C to 125°C) and higher current rating (3.2A per contact) compared to the original specification, providing enhanced performance margins. The TMM series uses liquid crystal polymer insulation material, which offers superior thermal and mechanical stability. This part is actively produced with ROHS3 and REACH compliance certifications.

Tertiary Options: Samtec TMM-120-01-F-D-RA-001 through TMM-120-01-F-D-RA-008

These Samtec variants provide identical electrical and mechanical interface specifications to the primary TMM-120-01-F-D-RA but with 39 of 40 positions loaded. These parts are suitable only for applications where the single unloaded position does not impact circuit functionality. All variants maintain active production status with full compliance certifications.

Compliance and Supply Considerations:

All recommended substitutes are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part's environmental specifications. The Molex and Samtec options provide established supply chains with multiple distributors, reducing procurement risk compared to the obsolete Amphenol ICC part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0877604017 be used as a direct drop-in replacement for the 86453-140LF?

A: The Molex 0877604017 maintains identical mating pitch (2.00mm), row spacing (2.00mm), position count (40), contact configuration (male pins), and finish specifications (gold mating, tin post). The primary interface dimensions are compatible. Minor variations exist in contact length and insulation height; PCB layout verification is required to confirm mechanical clearance in the specific application.

Q: What is the difference between the Samtec TMM-120-01-F-D-RA and the TMM-120-01-F-D-RA-001 through -008 variants?

A: The TMM-120-01-F-D-RA provides all 40 positions fully loaded. The TMM-120-01-F-D-RA-001 through -008 variants load 39 of 40 positions, with one position remaining unloaded. Selection depends on whether the application requires all 40 signal paths or can function with 39 active positions.

Q: Are there operating temperature differences between the substitute parts and the original 86453-140LF?

A: The original 86453-140LF operates from -40°C to 105°C. The Samtec TMM series extends this range to -55°C to 125°C, providing wider environmental coverage. The Molex 0877604017 does not specify operating temperature limits in the provided data. For applications requiring the original temperature range, the Samtec option provides additional margin.

Q: What insulation material differences exist between the substitute options?

A: The original 86453-140LF uses polyamide (PA) nylon with glass filler. The Molex 0877604017 uses polycyclohexylenedimethylene terephthalate (PCT) with glass filler. The Samtec TMM series uses liquid crystal polymer (LCP). All three materials meet UL94 V-0 flammability requirements where specified. LCP provides superior dimensional stability and thermal performance compared to PA and PCT.

Q: Can the Samtec TMM variants with 39 positions be used in applications designed for 40-position connectors?

A: The 39-position variants are mechanically and electrically compatible with 40-position mating connectors. However, the unloaded position will not establish electrical contact. These parts are suitable only for applications where the missing position does not carry critical signals or where the circuit design accommodates a single unused position.

Q: What is the current rating difference between the original part and substitutes?

A: The original 86453-140LF is rated at 2A per the specification. The Samtec TMM series is rated at 3.2A per contact, providing higher current capacity. The Molex 0877604017 does not specify current rating in the provided data. For applications operating near the 2A limit, the Samtec option provides additional current margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Molex 0877604017 and all Samtec TMM variants carry ROHS3 compliance certification. The original 86453-140LF does not specify ROHS status. All substitutes meet current regulatory requirements for restricted substance compliance.

Q: What packaging options are available for the substitute parts?

A: The Molex 0877604017 is supplied in tray packaging. The Samtec TMM-120-01-F-D-RA is supplied in bulk packaging. The Samtec TMM variants (TMM-120-01-F-D-RA-001 through -008) do not specify packaging format in the provided data. Packaging selection may impact procurement lead times and handling requirements.
