Engineering Selection Recommendations
All Samtec Tiger Claw™ SSM series substitutes listed above are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete 3M 963250-2000-AR-TP.
Selection by Connector Type:
For applications requiring bottom entry configuration, select SSM-125-F-DV-BE-LC or SSM-125-F-DV-BE-P-TR. The SSM-125-F-DV-BE-LC includes board lock features, while SSM-125-F-DV-BE-P-TR includes pick-and-place compatibility.
For pass-through applications, the SSM-125-F-DV series offers multiple variants. SSM-125-F-DV-LC and SSM-125-F-DV-LC-K include board lock features. SSM-125-F-DV-LC-K-TR is packaged in tape and reel format for automated assembly. SSM-125-F-DV-K and SSM-125-F-DV-P-TR include pick-and-place features.
Selection by Packaging:
For manual assembly or low-volume applications, tube packaging is available in SSM-125-F-DV, SSM-125-F-DV-BE-LC, SSM-125-F-DV-K, SSM-125-F-DV-LC, and SSM-125-F-DV-LC-K.
For automated assembly, tape and reel packaging is available in SSM-125-F-DV-LC-K-TR.
For bulk procurement, SSM-125-F-DV-A is available in bulk packaging.
All substitutes exceed the original current rating (5.2A per contact vs. 2A) and extend the operating temperature range (-55°C ~ 125°C vs. -25°C ~ 105°C), providing enhanced performance margins.
Frequently Asked Questions (FAQ)
Q: Can Samtec SSM-125 series connectors directly replace the 3M 963250-2000-AR-TP?
A: Yes. All Samtec SSM-125 variants listed maintain identical mating pitch (0.100"), position count (50), row configuration (2 rows), and contact type (female socket). The connectors are mechanically and electrically compatible for board-to-board applications.
Q: What is the difference between pass-through and bottom entry connector types?
A: Pass-through connectors allow signal routing through the connector body, while bottom entry connectors restrict entry to the bottom surface. Selection depends on PCB layout requirements and signal routing architecture.
Q: Does the higher current rating (5.2A per contact) affect compatibility?
A: No. Higher current rating indicates improved contact design and material composition. The connector operates safely at the original 2A specification while providing additional capacity margin for future design iterations.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All Samtec SSM-125 variants listed are ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets.
Q: What packaging options are available for automated assembly?
A: SSM-125-F-DV-LC-K-TR is supplied in tape and reel format. SSM-125-F-DV-K and SSM-125-F-DV-P-TR include pick-and-place features for automated placement equipment.
Q: How do the operating temperature ranges compare?
A: The original 3M connector operates from -25°C to 105°C. All Samtec substitutes operate from -55°C to 125°C, providing extended low-temperature performance and higher thermal margin for high-reliability applications.
Q: What is the difference between SSM-125-F-DV-LC and SSM-125-F-DV-LC-K?
A: SSM-125-F-DV-LC includes board lock features. SSM-125-F-DV-LC-K adds pick-and-place compatibility for automated assembly processes.
