SC20ML1S31 Equivalent & Substitute Parts

Part Overview

The SC20ML1S31 is a socket contact from the Trim Trio® SM/SC-M series manufactured by Souriau-Sunbank by Eaton. This stamped socket contact is designed for crimp termination of 20-22 AWG wire and features gold plating on a copper alloy base. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when bulk packaging requirements differ from standard offerings.

Substitute Part Grouping Explanation

The SC20ML1S31 has one identified substitute: SC20ML-1D70. Both parts share identical functional and electrical specifications within the Trim Trio® SM/SC-M series. The substitution is valid based on the following matching parameters:

• Contact type: Socket
• Termination method: Crimp
• Wire gauge range: 20-22 AWG
• Contact material: Copper Alloy
• Contact finish: Gold
• Manufacturing process: Stamped
• Series designation: Trim Trio® SM/SC-M
• Base product number: SC20ML
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The primary difference between these parts is packaging configuration and contact finish thickness specification. SC20ML1S31 specifies flash gold plating, while SC20ML-1D70 specifies 5.11µin (0.130µm) gold plating thickness.

Parameter Comparison

Engineering Selection Recommendations

Both SC20ML1S31 and SC20ML-1D70 are active production parts with identical compliance certifications. Selection between these parts should be based on:

Packaging Requirements: SC20ML-1D70 is supplied in bulk packaging, making it suitable for high-volume assembly operations. SC20ML1S31 uses standard packaging appropriate for lower-volume applications or component kits.

Gold Plating Specification: SC20ML-1D70 provides explicit gold plating thickness of 5.11µin (0.130µm), while SC20ML1S31 specifies flash plating. Applications requiring defined plating thickness specifications should reference SC20ML-1D70.

Regulatory Compliance: Both parts meet ROHS3 and REACH requirements, with unlimited moisture sensitivity rating suitable for standard storage and handling conditions.

Inventory Availability: SC20ML-1D70 maintains higher stock levels (2945 pcs) compared to SC20ML1S31 (915 pcs), supporting extended lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can SC20ML-1D70 be used as a direct replacement for SC20ML1S31?

A: Yes. Both parts are socket contacts within the Trim Trio® SM/SC-M series with identical wire gauge (20-22 AWG), termination method (crimp), contact material (copper alloy), and gold finish. The parts are functionally equivalent for connector assembly applications.

Q: What is the difference between flash gold plating and 5.11µin thickness?

A: Flash plating refers to a minimal gold coating applied to the contact surface, while 5.11µin (0.130µm) specifies a defined thickness measurement. SC20ML-1D70 provides explicit plating thickness specification for applications requiring controlled coating parameters.

Q: Are there packaging differences between these parts?

A: Yes. SC20ML1S31 uses standard packaging, while SC20ML-1D70 is supplied in bulk packaging. Bulk packaging is typically used for high-volume manufacturing environments where component quantities are consumed rapidly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC20ML1S31 and SC20ML-1D70 are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For high-volume production with bulk component needs, SC20ML-1D70 is appropriate. For applications requiring standard packaging or lower quantities, SC20ML1S31 is suitable. Both parts are active production items with equivalent electrical and mechanical performance.
