Key Parameters

Substitute Part Grouping Explanation

The SSM-125-L-DV-P-TR is identified as a substitute for the SSM-125-L-DV-M-TR based on the following criteria:

Both parts share identical electrical and mechanical specifications across all critical parameters: 50-position configuration, 0.100" (2.54mm) pitch, 2-row layout, surface mount termination, gold mating contact finish, 5.2A per contact current rating, and 405VAC/572VDC voltage rating. Both operate across the same temperature range (-55°C ~ 125°C) and utilize Liquid Crystal Polymer insulation material.

The substitution is valid because the parts differ only in fastening type designation within the same connector family. Both maintain identical contact geometry, mating interface, and electrical performance characteristics. The difference in part number suffix reflects a variation in fastening mechanism classification rather than a change to core electrical or mechanical compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the SSM-125-L-DV-M-TR and SSM-125-L-DV-P-TR are active production parts with ROHS3 compliance and identical electrical ratings. Selection between these parts should be based on availability and inventory levels. The SSM-125-L-DV-M-TR currently has 869 units in stock, while the SSM-125-L-DV-P-TR has 849 units available. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and are suitable for immediate use without baking requirements. The ECCN classification (EAR99) and HTSUS code (8536.69.4040) are identical for both parts.

Frequently Asked Questions (FAQ)

Q: Can SSM-125-L-DV-P-TR be used as a direct replacement for SSM-125-L-DV-M-TR?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. They share identical contact configurations, pitch, row spacing, current and voltage ratings, and operating temperature range.

Q: What is the difference between the M and P designations in the part numbers?

A: The M and P suffixes indicate different fastening type classifications within the Tiger Claw™ SSM series. This variation does not affect electrical performance or mating interface compatibility.

Q: Are both parts suitable for surface mount assembly?

A: Yes. Both the SSM-125-L-DV-M-TR and SSM-125-L-DV-P-TR are surface mount connectors with solder termination and include pick-and-place features for automated assembly.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures.

Q: Are these parts RoHS compliant?

A: Yes. Both the SSM-125-L-DV-M-TR and SSM-125-L-DV-P-TR are ROHS3 compliant.

Q: What is the contact material and finish specification?

A: Both parts feature phosphor bronze contacts with gold mating finish (10.0µin / 0.25µm thickness) and tin post finish. The gold plating ensures reliable low-resistance connections.
