SS28W1T Equivalent & Substitute Parts

Part Overview

The SS28W1T is a socket contact for circular connectors manufactured by Amphenol Sine Systems Corp, part of the ecomate® RM series. This component is rated for 28-30 AWG wire gauges with Size 20 crimp termination and tin plating. The part is currently at obsolete product status, requiring evaluation of active equivalent models for ongoing procurement and design applications. Substitution is necessary to maintain supply chain continuity and access to manufacturer support for new installations and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS28W1T is based on strict electrical and mechanical compatibility across the following parameters:

• Contact Size: Must be Size 20 (socket configuration)
• Wire Gauge Range: Must accommodate 28-30 AWG (0.05 ~ 0.08mm²)
• Termination Type: Must be crimp-style termination
• Contact Material & Finish: Must be copper alloy with tin plating
• Insulation Support: Must include insulation support feature
• Regulatory Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The SSP28W2T meets all substitution criteria as an active product with identical electrical and mechanical parameters. The primary distinction is the product series (ecomate® Aquarius™ versus ecomate® RM) and active availability status.

Parameter Comparison

Engineering Selection Recommendations

The SSP28W2T is the direct equivalent substitute for the SS28W1T. Both parts are manufactured by Amphenol Sine Systems Corp and maintain identical electrical and mechanical specifications across all critical parameters. The SSP28W2T carries active product status, providing assured supply chain availability and ongoing manufacturer technical support. Both parts satisfy ROHS3 compliance requirements and REACH regulatory obligations, making the SSP28W2T suitable for applications requiring equivalent performance without design modification. The transition from the ecomate® RM series (SS28W1T) to the ecomate® Aquarius™ series (SSP28W2T) represents a natural product line evolution within the manufacturer's portfolio.

Frequently Asked Questions (FAQ)

Q: Can the SSP28W2T directly replace the SS28W1T in existing designs? A: Yes. The SSP28W2T is electrically and mechanically equivalent across all specified parameters. No design changes are required for substitution in applications currently using the SS28W1T.

Q: Are there series compatibility concerns between ecomate® RM and ecomate® Aquarius™? A: No. The series designation reflects the product line rather than functional capability. Both series utilize identical socket contact specifications for Size 20 crimp terminations in the 28-30 AWG range.

Q: Do both parts meet the same regulatory standards? A: Yes. The SS28W1T and SSP28W2T are both ROHS3 compliant and REACH unaffected. No regulatory differences exist between the parts.

Q: Why is the SS28W1T obsolete while SSP28W2T is active? A: Product obsolescence reflects manufacturer lifecycle management and series consolidation. The SSP28W2T represents the active continuation within the ecomate® Aquarius™ series and is the recommended part for procurement.

Q: Are there inventory implications for substitution? A: The SSP28W2T has documented inventory of 794 pieces in new original stock, ensuring procurement availability for new installations and production requirements.

Q: Do the tin-plated copper alloy contacts perform identically in both parts? A: Yes. Contact material and finish specifications are identical, ensuring equivalent electrical performance, contact resistance, and environmental protection.
