SS-31-10 Spade Terminal Connector Equivalent & Substitute Parts

Part Overview

The SS-31-10 is a 10 stud spade terminal connector manufactured by 3M, designed for crimp termination of 18-22 AWG wire. This non-insulated spring snap terminal operates as a free-hanging in-line connector with a butted seam construction. The part is currently active in production and RoHS compliant.

Substitute parts may be required due to supply chain constraints, inventory availability, or specific application requirements where alternative manufacturers' offerings meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-31-10 is determined by strict alignment of the following critical parameters:

• Stud/Tab Size: Must be 10 Stud
• Wire Gauge: Must be 18-22 AWG
• Terminal Type: Must be Spring, Snap
• Termination Method: Must be Crimp
• Mounting Type: Must be Free Hanging (In-Line)
• Insulation: Must be Non-Insulated
• Overall Length: Must be 0.680" (17.27mm)
• Ring Center to Termination Length: Must be 0.250" (6.35mm)
• Termination Length: Must be 0.250" (6.35mm)

Two substitute parts meet these criteria: Keystone Electronics 8256 and Panduit Corp P18-10LF-C. Both maintain functional equivalence across all critical electrical and mechanical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 8256 is the primary substitute for the SS-31-10. Both parts are active products with current manufacturing status and equivalent RoHS compliance. The 8256 maintains identical critical dimensions for overall length, ring center to termination length, and termination length. Minor variations in outer edge width (0.320" versus 0.300") remain within acceptable tolerance for mechanical fit in standard 10 stud applications.

The Panduit Corp P18-10LF-C is listed as obsolete and should not be selected for new designs or long-term supply requirements. While it meets the core stud size and wire gauge specifications, its obsolete status and unspecified dimensional parameters for ring center to termination and termination lengths present supply and compatibility risks.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8256 be used as a direct replacement for the SS-31-10?

A: Yes. The 8256 meets all critical electrical and mechanical parameters: 10 stud size, 18-22 AWG wire gauge, spring snap terminal type, crimp termination, free-hanging in-line mounting, and non-insulated construction. Dimensional alignment on overall length and termination dimensions is identical.

Q: What is the significance of the width difference between SS-31-10 (0.300") and 8256 (0.320")?

A: The outer edge width variation of 0.020" is a minor dimensional difference that does not affect functional compatibility in standard 10 stud connector applications. Both parts maintain the same stud size and termination geometry.

Q: Why is the Panduit P18-10LF-C listed as a substitute if it is obsolete?

A: The P18-10LF-C is included in the substitute list based on historical equivalence data. However, its obsolete status means it is no longer in active production. New designs and applications should prioritize the active Keystone Electronics 8256 for supply chain reliability.

Q: Are there compliance differences between these three parts?

A: The SS-31-10 and 8256 are both RoHS compliant with MSL rating 1 (unlimited moisture sensitivity). The P18-10LF-C is ROHS3 compliant with MSL not applicable. All three parts carry EAR99 ECCN classification and REACH unaffected status.

Q: What packaging is available for these substitute parts?

A: All three parts are supplied in bulk packaging. Current inventory includes 931 pcs for SS-31-10, 1017 pcs for 8256, and 753 pcs for P18-10LF-C.
