SS20W1T Socket Contact Equivalent & Substitute Parts

Part Overview

The SS20W1T is a socket contact manufactured by Amphenol Sine Systems Corp, designed for use in the ecomate® RM circular connector series. This component is a signal-type, stamped socket contact rated for 20-22 AWG wire gauges with crimp termination and tin finish. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this contact specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SS20W1T is based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Contact Type: Socket
• Contact Size: 20
• Wire Gauge Range: 20-22 AWG (0.34 ~ 0.5 mm²)
• Contact Termination: Crimp
• Contact Material: Copper Alloy
• Contact Finish: Tin
• Features: Insulation Support
• Base Product Number: SS20
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The SS20W2T meets all mandatory parameters and is classified as an active product, making it a direct functional equivalent for the obsolete SS20W1T. Both contacts share identical electrical and mechanical specifications within the ecomate® connector family.

Parameter Comparison

Engineering Selection Recommendations

The SS20W2T is the direct equivalent substitute for the obsolete SS20W1T. Selection of SS20W2T is based on the following engineering criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental regulations.

Product Status: The SS20W2T is classified as an active product with substantial inventory availability (12,803 pieces), whereas the SS20W1T is obsolete. Transition to SS20W2T ensures long-term supply chain reliability.

Electrical and Mechanical Equivalence: All critical parameters—contact size, wire gauge range, termination method, material composition, and finish specification—are identical between the two parts. No functional differences exist in connector applications.

Packaging Consideration: The SS20W2T is supplied in Cut Tape (CT) packaging, which is standard for component distribution and integration into automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SS20W2T be used as a direct replacement for SS20W1T in existing designs?

A: Yes. The SS20W2T is electrically and mechanically equivalent to the SS20W1T. All contact specifications, including size, wire gauge range, termination type, material, and finish, are identical. No design modifications are required.

Q: What is the difference between the ecomate® RM series (SS20W1T) and ecomate® Aquarius™ series (SS20W2T)?

A: Both contacts share identical electrical and mechanical specifications. The series designation reflects product line organization within Amphenol's portfolio. The functional performance of the socket contact remains unchanged.

Q: Why is SS20W1T classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The SS20W2T represents the active equivalent within the current product portfolio.

Q: Are there any compatibility issues with connector housings or mating pins?

A: No compatibility issues exist. The SS20W2T maintains identical contact size (20) and mechanical dimensions, ensuring full compatibility with existing connector assemblies designed for SS20W1T.

Q: What is the significance of the Cut Tape (CT) packaging for SS20W2T?

A: Cut Tape packaging is standard for component distribution and is compatible with automated pick-and-place assembly equipment. This packaging format does not affect the electrical or mechanical performance of the contact.

Q: Are both parts compliant with current environmental and trade regulations?

A: Yes. Both SS20W1T and SS20W2T are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
