SS20M1F Equivalent & Substitute Parts

Part Overview

The SS20M1F is a socket contact connector from Amphenol Sine Systems Corp's ecomate® RM series, designed for 20-22 AWG wire applications in circular connector assemblies. This component is classified as Obsolete, necessitating identification of equivalent substitute parts for continued procurement and system integration. The SS20M2F serves as a direct functional replacement, providing identical electrical and mechanical specifications while maintaining active market availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS20M1F with the SS20M2F is based on strict equivalence of the following critical parameters:

• Contact Configuration: Both parts are socket contacts with Size 16 designation
• Wire Gauge Compatibility: Identical 20-22 AWG (0.34 ~ 0.5 mm²) range for wire acceptance
• Termination Method: Both utilize crimp termination without modification to connector assembly tooling
• Electrical Properties: Matching copper alloy material and gold flash finish ensure equivalent contact resistance and signal integrity
• Mechanical Interface: Shared base product number (SS20) and identical insulation support features confirm physical interchangeability
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status

The SS20M2F is a direct substitute within the ecomate® product family, with the primary distinction being active production status and availability in Cut Tape packaging.

Parameter Comparison

Engineering Selection Recommendations

The SS20M2F is the appropriate selection for applications currently using or specifying the SS20M1F. The substitute part maintains full electrical and mechanical compatibility while providing the advantage of active product status and confirmed market availability. Both parts satisfy ROHS3 compliance requirements and REACH regulatory frameworks, ensuring consistency with environmental and supply chain standards. The transition from SS20M1F to SS20M2F presents no engineering risk with respect to connector assembly, signal performance, or regulatory standing.

Frequently Asked Questions (FAQ)

Q: Are the SS20M1F and SS20M2F mechanically interchangeable? A: Yes. Both contacts share Size 16 designation, identical insulation support features, and equivalent base product number (SS20), ensuring direct interchangeability in connector assemblies without modification to mating hardware or tooling.

Q: Can SS20M2F be used in applications originally designed for SS20M1F? A: Yes. Electrical and mechanical parameters are identical, including wire gauge range (20-22 AWG), crimp termination method, contact material composition, and gold flash finish. No design revision is required.

Q: What is the difference between the two part numbers? A: The SS20M2F represents the active production continuation within the ecomate® Aquarius™ series. The SS20M1F belongs to the ecomate® RM series and is no longer manufactured. Functionally, the parts are equivalent.

Q: Are there packaging considerations for SS20M2F? A: The SS20M2F is supplied in Cut Tape (CT) packaging. Verify that procurement and assembly processes accommodate this packaging format. The SS20M1F's original packaging specification is not provided in this reference.

Q: Do both parts satisfy the same compliance requirements? A: Yes. Both the SS20M1F and SS20M2F are ROHS3 compliant and REACH unaffected, maintaining consistency with environmental and chemical composition regulations.

Q: Is the MSL rating the same for both parts? A: Yes. Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
