Substitute Part Grouping Explanation

Substitution eligibility for the TSM-104-01-L-DV-A-P is determined by strict alignment of the following parameters:

Connector type classification (Header, Cuttable)
Contact type (Male Pin)
Position count and row configuration (8 positions, 2 rows)
Mating pitch and row spacing (0.100" / 2.54mm)
Mounting technology (Surface Mount)
Termination method (Solder)
Shrouding configuration (Unshrouded)
Fastening type (Push-Pull)
Contact shape (Square)
Insulation material compatibility
Compliance certifications (RoHS3, REACH Unaffected)

The M20-8760442 manufactured by Harwin Inc. meets all critical substitution criteria across these parameters, establishing it as a direct equivalent for the TSM-104-01-L-DV-A-P.

Engineering Selection Recommendations

Both the TSM-104-01-L-DV-A-P and M20-8760442 are active production components with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts carry UL94 V-0 flammability ratings and unlimited moisture sensitivity classification (MSL 1), indicating robust environmental performance characteristics.

The TSM-104-01-L-DV-A-P operates across a wider temperature range (-55°C to 125°C) compared to the M20-8760442 (-40°C to 105°C). Selection between these parts should be based on specific application temperature requirements. The M20-8760442 provides additional electrical specifications (3A per contact, 250V rating) and defined mated stacking heights, which may be relevant for applications requiring explicit electrical performance data.

Contact length variance between the two parts is minimal (0.230" versus 0.228"), representing a 0.002" difference that does not affect mechanical compatibility in standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Are the TSM-104-01-L-DV-A-P and M20-8760442 mechanically interchangeable?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), row configuration (2 rows, 8 positions), mounting type (surface mount), and contact geometry (square male pins). The contact length difference of 0.002" does not affect standard board-to-board mating applications.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation material (LCP versus Polyamide/Nylon 6T), operating temperature range (TSM-104-01-L-DV-A-P: -55°C to 125°C; M20-8760442: -40°C to 105°C), and packaging format (Samtec: Tube; Harwin: Bulk). The M20-8760442 includes specified electrical ratings (3A per contact, 250V).

Q: Can I use the M20-8760442 in applications requiring the full -55°C to 125°C temperature range?

A: No. The M20-8760442 is rated only to -40°C minimum and 105°C maximum. Applications requiring the full -55°C to 125°C range must use the TSM-104-01-L-DV-A-P.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TSM-104-01-L-DV-A-P and M20-8760442 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.

Q: What is the difference in packaging between these parts?

A: The TSM-104-01-L-DV-A-P is supplied in tube packaging, while the M20-8760442 is supplied in bulk packaging. This affects handling, storage, and pick-and-place automation considerations.

Q: Do both connectors support push-pull fastening?

A: Yes. Both connectors utilize push-pull fastening type and are classified as cuttable headers suitable for board-to-board or cable applications.
