Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSM-120-L-DV-LC-P-TR is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 40 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Connector Type & Contact: Receptacle, pass-through, female socket contacts
• Mounting & Termination: Surface mount with solder termination
• Electrical Performance: 5.2A per contact, 405VAC / 572VDC voltage rating
• Environmental Compliance: ROHS3 compliant, MSL 1, operating temperature -55°C ~ 125°C
• Material & Finish: LCP insulation, gold-plated mating contacts (10.0µin thickness), tin-plated posts

The SSM-120-L-DV-LC-M-TR maintains all these parameters and qualifies as a direct substitute within the Tiger Claw™ SSM series.

Both parts are suitable for high-density board-to-board interconnect applications requiring reliable push-pull fastening and gold-plated contact surfaces.

Frequently Asked Questions (FAQ)

Q: Can SSM-120-L-DV-LC-M-TR be used as a direct replacement for SSM-120-L-DV-LC-P-TR?

A: Yes. Both parts share identical electrical and mechanical specifications including 40-position configuration, 0.100" pitch, 5.2A per contact current rating, 405VAC / 572VDC voltage rating, surface mount termination, and push-pull fastening. All compliance certifications and environmental ratings are equivalent.

Q: What is the difference between these two part numbers?

A: The provided specifications indicate both parts are functionally equivalent within the Tiger Claw™ SSM series. Differences in part numbering reflect internal Samtec designation but do not affect electrical or mechanical performance for standard applications.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate across -55°C to 125°C, supporting standard industrial and commercial temperature ranges. Specific application requirements should be evaluated against this operating window.

Q: What is the significance of the gold plating specification?

A: The 10.0µin (0.25µm) gold plating on mating contacts ensures reliable electrical contact and corrosion resistance. This specification is identical across both parts.

Q: Can these connectors be used in RoHS-restricted applications?

A: Yes. Both SSM-120-L-DV-LC-P-TR and SSM-120-L-DV-LC-M-TR are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What packaging format is used for these connectors?

A: Both parts are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly processes.
