Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSM-125-L-DV-LC-P is determined by strict equivalence across the following critical parameters:

• Connector Interface: 50-position receptacle, pass-through configuration with 0.100" (2.54mm) pitch and 2-row layout
• Electrical Performance: 5.2A per contact current rating and 405VAC/572VDC voltage rating
• Mechanical Mounting: Surface mount termination with push-pull fastening and board lock features
• Contact Specifications: Female socket contacts with gold mating finish and phosphor bronze material
• Environmental Compliance: ROHS3 compliance and -55°C to 125°C operating temperature range
• Insulation Material: Liquid Crystal Polymer (LCP) with black color and 0.290" (7.37mm) height

The identified substitute part SSM-125-L-DV-LC-K matches all critical parameters within this specification set, confirming direct functional equivalence for circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

Both SSM-125-L-DV-LC-P and SSM-125-L-DV-LC-K are active production parts from Samtec Inc. with ROHS3 compliance certification. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical, mechanical, and environmental specifications are identical. The SSM-125-L-DV-LC-P currently maintains higher inventory levels (1018 pcs) compared to SSM-125-L-DV-LC-K (705 pcs), which may influence supply chain decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can SSM-125-L-DV-LC-K be used as a direct replacement for SSM-125-L-DV-LC-P in existing circuit board designs?

A: Yes. Both parts share identical electrical ratings (5.2A per contact, 405VAC/572VDC), mechanical dimensions (50-position, 0.100" pitch, 2-row configuration), mounting specifications (surface mount), and environmental operating range (-55°C to 125°C). No circuit board redesign or component qualification is required.

Q: Are there any differences in the contact interface or mating characteristics?

A: No. Both parts feature identical female socket contacts with gold mating finish (10.0µin thickness), phosphor bronze material, and square contact geometry. Mating compatibility with corresponding plug connectors is equivalent.

Q: What is the significance of the different part number suffix (P vs. K)?

A: The suffix variation indicates a manufacturing or packaging distinction within Samtec's product line. All functional and electrical specifications remain identical between the two part numbers.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and carry Moisture Sensitivity Level 1 (unlimited shelf life). Selection should be based on specific application requirements and any additional qualification standards mandated by the end-use industry.

Q: Can these connectors be used in applications requiring pass-through functionality?

A: Yes. Both parts are specified as pass-through receptacles, enabling signal routing through the connector assembly for daisy-chain or multi-stage board configurations.
