BS-31-6-P Equivalent & Substitute Parts

Part Overview

The BS-31-6-P is a red 6 stud spade terminal connector manufactured by 3M, designed for crimp termination of 18-22 AWG wire. This insulated terminal features a tin-plated copper contact with vinyl insulation and is classified as an active product in full production. Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain continuity in applications where the primary part may experience supply constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BS-31-6-P is determined by strict equivalence across the following critical parameters:

• Stud/Tab Size: 6 Stud (mechanical interface requirement)
• Wire Gauge: 18-22 AWG (electrical and mechanical compatibility)
• Termination Method: Crimp (assembly process compatibility)
• Insulation Type: Insulated with Vinyl material (electrical safety and environmental protection)
• Color: Red (circuit identification and traceability)
• Contact Material: Copper, ETP with Tin finish (electrical conductivity and corrosion resistance)
• Insulation Diameter: 0.145" (3.68mm) (wire fit and mechanical tolerance)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and environmental requirements)

The Keystone Electronics 8227 meets all critical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the BS-31-6-P and the Keystone Electronics 8227 are active products with full ROHS3 compliance and MSL 1 ratings, ensuring regulatory alignment and environmental stability. The primary dimensional difference is overall length: the BS-31-6-P measures 0.850" (21.59mm) while the 8227 measures 0.700" (17.78mm). This variation does not affect the critical functional parameters—stud size, wire gauge, termination method, contact material, and insulation specifications remain identical.

Selection between these parts should be based on application-specific space constraints and mechanical assembly requirements. Both parts maintain equivalent electrical performance and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8227 be used as a direct replacement for the BS-31-6-P?

A: Yes, the 8227 is a manufacturer-recommended equivalent. All critical electrical and mechanical parameters are identical, including stud size, wire gauge, contact material, and insulation specifications. The overall length difference (0.150" shorter) must be evaluated against application-specific space requirements.

Q: What is the significance of the overall length difference between these parts?

A: The BS-31-6-P has an overall length of 0.850" (21.59mm), while the 8227 measures 0.700" (17.78mm). This 0.150" difference does not affect electrical performance or the critical ring center to termination distance (0.250" in both cases). The difference is relevant only for applications with strict spatial constraints or where the terminal extends into a confined area.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the BS-31-6-P and the 8227 are ROHS3 compliant and carry an MSL 1 rating, indicating unlimited moisture sensitivity protection and full compliance with current environmental and regulatory requirements.

Q: What wire gauges are compatible with these terminals?

A: Both terminals are rated for 18-22 AWG wire. This range encompasses standard industrial and commercial wiring applications. Wire gauge selection must match the terminal's crimp specifications for proper electrical contact and mechanical security.

Q: Are there any packaging or inventory considerations when switching between these parts?

A: Both parts are supplied in bulk packaging. Current inventory shows 1094 pieces of the BS-31-6-P and 777 pieces of the 8227 available. Packaging format and minimum order quantities should be confirmed with the supplier based on application requirements.
