BS-31-6 Equivalent & Substitute Parts

Part Overview

The BS-31-6 is a 6 stud spade terminal connector manufactured by 3M, designed for crimp termination of 18-22 AWG wire. This non-insulated copper terminal features tin contact finish and is classified as Active product status. Equivalent parts are identified when identical electrical and mechanical parameters are maintained across wire gauge, stud size, termination method, and physical dimensions, ensuring direct functional interchangeability in applications requiring spade terminal connectors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BS-31-6 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 crimp die compatibility)
• Termination Method: Crimp (assembly process compatibility)
• Physical Dimensions: Width 0.300" (7.62mm), Length 0.650" (16.50mm), Length - Ring Center to Termination 0.250" (6.35mm)
• Contact Material: Copper, ETP (electrical conductivity and corrosion resistance)
• Contact Finish: Tin (surface protection and solderability)
• Insulation Type: Non-Insulated (form factor requirement)
• Regulatory Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The Keystone Electronics 8218 maintains all specified parameters and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the BS-31-6 and the Keystone Electronics 8218 are Active product status components with full ROHS3 compliance and unlimited moisture sensitivity level rating. Selection between these equivalents may be based on availability, lead time, or procurement requirements, as all electrical and mechanical parameters are identical. Both parts meet the same regulatory and environmental standards (ECCN: EAR99, HTSUS: 8536.90.4000).

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8218 be used as a direct replacement for the BS-31-6?

A: Yes. The 8218 maintains identical stud size (6 Stud), wire gauge (18-22 AWG), physical dimensions, contact material (Copper, ETP), contact finish (Tin), and termination method (Crimp). Both are non-insulated terminals with equivalent regulatory compliance.

Q: What parameters must remain constant for substitution?

A: Stud/Tab size, wire gauge, overall length, width, ring center to termination length, contact material, contact finish, insulation type, and termination method must all match exactly.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Bulk packaging. The BS-31-6 has 1208 pcs in stock, while the 8218 has 1030 pcs in stock.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BS-31-6 and 8218 are ROHS3 compliant with MSL 1 (Unlimited) rating. The 8218 additionally carries REACH Unaffected status.
