SC16ML1S31 Equivalent & Substitute Parts Reference

Part Overview

The SC16ML1S31 is an active socket contact manufactured by Souriau-Sunbank by Eaton, designed for crimp termination applications in the Trim Trio® SM/SC-M connector series. This stamped copper alloy contact with gold finish is specified for 16-18 AWG wire gauges and operates at Moisture Sensitivity Level 1 (unlimited). The part is ROHS3 compliant and REACH unaffected, making it suitable for regulated industrial and commercial applications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the contact family, ensuring functional interchangeability within the same connector system.

Substitute Part Grouping Explanation

Substitute parts for the SC16ML1S31 are identified based on strict equivalence across the following critical parameters:

Substitution Criteria:

• Same base product number (SC16ML)
• Identical contact type (Stamped socket)
• Identical termination method (Crimp)
• Identical wire gauge specification (16-18 AWG)
• Identical contact material (Copper alloy)
• Identical contact finish (Gold)
• Identical series designation (Trim Trio® SM/SC-M)
• Identical product status (Active)
• Identical compliance certifications (ROHS3, REACH Unaffected)
• Identical MSL rating (1 - Unlimited)

The SC16ML1S31 and SC16ML-1D70 share all critical electrical and mechanical parameters. Differences in packaging format (bulk versus standard) and contact finish thickness specification do not affect functional interchangeability within the connector assembly.

Parameter Comparison

Engineering Selection Recommendations

SC16ML1S31 Primary Selection: Select SC16ML1S31 when standard packaging format is required for controlled inventory management and component traceability in regulated manufacturing environments.

SC16ML-1D70 Alternative Selection: SC16ML-1D70 is functionally equivalent and interchangeable for applications where bulk packaging is acceptable. Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance (ROHS3, REACH Unaffected). The contact finish thickness difference (Flash versus 5.11µin) does not affect functional performance within the Trim Trio® SM/SC-M connector system.

Both parts are active products with unlimited moisture sensitivity rating, suitable for immediate procurement and deployment in 16-18 AWG crimp termination applications.

Frequently Asked Questions (FAQ)

Q: Can SC16ML-1D70 be used as a direct replacement for SC16ML1S31?

A: Yes. Both parts are functionally equivalent socket contacts with identical electrical and mechanical specifications. They share the same base product number (SC16ML), contact type (stamped), termination method (crimp), wire gauge (16-18 AWG), material (copper alloy), finish (gold), and series designation (Trim Trio® SM/SC-M). The primary difference is packaging format (bulk versus standard).

Q: What is the significance of the contact finish thickness difference?

A: SC16ML1S31 specifies Flash finish thickness, while SC16ML-1D70 specifies 5.11µin (0.130µm). Both finishes provide equivalent gold plating protection for the copper alloy base material. The difference reflects manufacturing specification variance within acceptable performance parameters for the contact family.

Q: Are both parts ROHS3 compliant?

A: Yes. Both SC16ML1S31 and SC16ML-1D70 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use in electrical and electronic equipment.

Q: What wire gauge range do these contacts support?

A: Both parts are specified for 16-18 AWG wire termination using crimp termination method.

Q: Can these socket contacts be mixed with other Trim Trio® SM/SC-M series components?

A: Yes. Both parts are members of the Trim Trio® SM/SC-M connector series and are designed for integration within this standardized connector family.

Q: What is the inventory status for each part?

A: SC16ML1S31 has 988 pieces in stock. SC16ML-1D70 has 1523 pieces in stock. Both are active products available for immediate procurement.
