Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS-31-6 are identified based on matching the following critical parameters:

• Stud/Tab Size: 6 Stud (mechanical interface requirement)
• Wire Gauge: 18-22 AWG (electrical and crimp specification)
• Width - Outer Edges: 0.250" (6.35mm) (dimensional compatibility)
• Length - Overall: 0.680" (17.27mm) (dimensional compatibility)
• Termination Type: Crimp (connection method)
• Terminal Type: Spring, Snap (functional behavior)
• Mounting Type: Free Hanging (In-Line) (installation configuration)
• Insulation: Non-Insulated (material specification)

The Keystone Electronics part number 8254 satisfies all these parameters, establishing it as a direct functional equivalent within the spade terminal connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the SS-31-6 and 8254 maintain active product status and comply with applicable regulatory requirements. The SS-31-6 carries RoHS Compliant certification, while the 8254 carries ROHS3 Compliant certification. Both parts are REACH Unaffected and classified under ECCN EAR99. Selection between these parts should be based on availability, supply chain requirements, and any design-specific preferences regarding contact material or finish specifications. The Keystone Electronics 8254 provides documented tin contact finish and copper ETP contact material, whereas the SS-31-6 does not specify these material properties in the available data.

Frequently Asked Questions (FAQ)

Q: What makes the Keystone Electronics 8254 a suitable substitute for the SS-31-6?

A: The 8254 matches all critical mechanical and electrical parameters: 6 stud size, 18-22 AWG wire gauge, 0.250" width, 0.680" overall length, crimp termination, spring snap terminal type, free-hanging in-line mounting, and non-insulated construction. These parameters define functional compatibility within the spade terminal connector category.

Q: Are there dimensional differences between these parts?

A: No. Both parts share identical outer edge width (0.250" / 6.35mm), overall length (0.680" / 17.27mm), ring center to termination length (0.250" / 6.35mm), and termination length (0.250" / 6.35mm).

Q: What is the difference in contact material specification?

A: The SS-31-6 does not specify contact material or finish in the provided data. The 8254 specifies tin contact finish with copper ETP contact material. This difference does not affect mechanical or electrical compatibility for the stated wire gauge and stud size.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the SS-31-6 and 8254 are rated for 18-22 AWG wire termination.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant (SS-31-6 is RoHS Compliant; 8254 is ROHS3 Compliant), REACH Unaffected, and classified as EAR99. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: Can these parts be used interchangeably in existing designs?

A: Substitution is based on matching the critical parameters listed in this reference. Both parts satisfy the mechanical interface (6 stud), electrical specification (18-22 AWG), and dimensional requirements. Design validation should confirm that any material or finish differences do not affect application performance.
