Substitute Part Grouping Explanation

Substitution of the obsolete SS28W1F is based on strict electrical and mechanical parameter alignment. The substitute part SS28W2F maintains identical specifications across all critical functional parameters: socket contact type, size 20 geometry, 28-30 AWG wire gauge capacity, crimp termination method, copper alloy material composition, and gold flash finish. Both parts share the same base product number (SS28), confirming design compatibility at the contact level.

The substitution is valid because the following parameters are identical:

• Contact Type: Socket
• Contact Size: 20
• Wire Gauge Range: 28-30 AWG (0.05 ~ 0.08 mm²)
• Contact Termination: Crimp
• Contact Material: Copper Alloy
• Contact Finish: Gold (Flash thickness)
• Insulation Support Feature: Present
• RoHS3 Compliance: Confirmed
• MSL Rating: 1 (Unlimited)

The primary distinction is product status: SS28W1F is obsolete, while SS28W2F is active production. SS28W2F is supplied in Cut Tape (CT) packaging format.

Parameter Comparison

Engineering Selection Recommendations

SS28W2F is the direct substitute for the obsolete SS28W1F. Selection of SS28W2F is based on the following engineering criteria:

Product Status: SS28W2F maintains active production status, ensuring long-term supply availability and manufacturing consistency. The obsolete status of SS28W1F creates supply risk for new designs and field service requirements.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, confirming equivalence for regulated applications.

Functional Equivalence: All electrical and mechanical parameters are identical, including contact geometry (size 20), wire gauge capacity (28-30 AWG), termination method (crimp), and material specifications (copper alloy with gold flash finish).

Packaging Consideration: SS28W2F is supplied in Cut Tape (CT) format. Verify packaging compatibility with existing assembly processes and equipment specifications.

Frequently Asked Questions (FAQ)

Q: Can SS28W2F be used as a direct replacement for SS28W1F in existing designs?

A: Yes. SS28W2F is electrically and mechanically equivalent to SS28W1F across all functional parameters. Both contacts are size 20 socket types with identical 28-30 AWG wire gauge capacity, crimp termination, and gold-plated copper alloy construction. The substitution is valid for circuit performance and connector assembly compatibility.

Q: What is the primary reason for substituting SS28W1F?

A: SS28W1F is classified as obsolete, creating supply chain risk. SS28W2F is the active production equivalent, ensuring availability for new production runs and field service applications.

Q: Are there any compliance differences between SS28W1F and SS28W2F?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Regulatory requirements are satisfied by either part.

Q: Does packaging format affect electrical or mechanical performance?

A: No. SS28W2F is supplied in Cut Tape (CT) packaging, which does not affect contact performance. Verify that CT packaging is compatible with your assembly equipment and processes.

Q: Are both parts from the same manufacturer?

A: Yes. Both SS28W1F and SS28W2F are manufactured by Amphenol Sine Systems Corp, confirming design consistency and quality standards.

Q: What wire gauges are supported by SS28W2F?

A: SS28W2F supports 28-30 AWG wire gauge range, equivalent to 0.05 ~ 0.08 mm² cross-sectional area. This specification is identical to SS28W1F.

Q: Is the contact finish specification the same for both parts?

A: Yes. Both parts feature gold flash finish on copper alloy contacts, providing identical electrical conductivity and corrosion resistance characteristics.
