Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS20W1G15 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact Size: 20
• Wire Gauge Range: 20-22 AWG (0.34 ~ 0.5mm²)
• Contact Termination: Crimp
• Contact Material: Copper Alloy
• Contact Finish: Gold at 15.0µin (0.38µm)

Mechanical Compatibility Parameters:

• Contact Type: Socket
• Base Product Number: SS20
• Insulation Support Feature

Regulatory & Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected Status
• MSL 1 (Unlimited)

The substitute part SS20W2G15 maintains identical electrical and mechanical specifications while offering active product status and alternative packaging configuration. Both components share the same base product number (SS20) and are manufactured by the same supplier, ensuring form, fit, and function compatibility within circular connector assemblies.

Parameter Comparison

Engineering Selection Recommendations

The SS20W2G15 is the direct equivalent substitute for the obsolete SS20W1G15. Both components are manufactured by Amphenol Sine Systems Corp and maintain identical electrical and mechanical specifications across all critical parameters including contact size, wire gauge range, termination method, material composition, and finish specifications.

The primary distinction between these components is product status: SS20W1G15 is obsolete while SS20W2G15 is active. This status difference, combined with SS20W2G15's Tape & Reel packaging configuration, positions it as the current production equivalent. Both components satisfy identical RoHS3 compliance and REACH requirements, ensuring regulatory continuity in applications requiring these certifications.

For new designs, production builds, and field service applications, SS20W2G15 is the appropriate selection. The active product status ensures ongoing manufacturer support, availability, and consistency with current manufacturing processes and quality standards.

Frequently Asked Questions (FAQ)

Q: Can SS20W2G15 be used as a direct replacement for SS20W1G15 in existing connector assemblies?

A: Yes. Both components share identical contact size (20), wire gauge range (20-22 AWG), termination method (crimp), material composition (copper alloy), and gold finish specifications (15.0µin). They are functionally and mechanically equivalent within circular connector applications.

Q: What is the significance of the product status difference between these parts?

A: SS20W1G15 is classified as obsolete, indicating discontinued production and limited availability. SS20W2G15 is active, meaning it is currently manufactured and supported by Amphenol Sine Systems Corp. For ongoing supply chain requirements, SS20W2G15 is the appropriate selection.

Q: Does the Tape & Reel packaging of SS20W2G15 affect its electrical or mechanical performance?

A: No. Packaging configuration (Tape & Reel versus other formats) does not alter the electrical or mechanical properties of the contact itself. Packaging affects handling, storage, and assembly processes but not component performance or compatibility.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both SS20W1G15 and SS20W2G15 are ROHS3 compliant and REACH unaffected. They maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited), ensuring equivalent regulatory compliance for applications requiring these certifications.

Q: What wire gauges are compatible with these socket contacts?

A: Both components are rated for 20-22 AWG wire, equivalent to 0.34 ~ 0.5mm² cross-sectional area. Wire gauge compatibility is identical between the two parts.

Q: Is the gold finish thickness the same on both components?

A: Yes. Both SS20W1G15 and SS20W2G15 feature identical gold plating at 15.0µin (0.38µm) thickness, ensuring equivalent contact resistance and corrosion protection characteristics.
