BS-21-8-P Equivalent & Substitute Parts

Part Overview

The BS-21-8-P is a red insulated spade terminal connector manufactured by 3M, designed for crimp termination of 18-22 AWG wire onto #8 studs. This flanged terminal features tin-plated copper contact material with vinyl insulation and is classified as Active product status. Equivalent and substitute parts are identified when all critical electrical and mechanical parameters align with the original specification, ensuring direct functional interchangeability in applications requiring #8 stud spade terminals with identical wire gauge and insulation properties.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BS-21-8-P is determined by strict alignment of the following critical parameters:

• Stud/Tab Size: Must be #8 stud
• Wire Gauge: Must accommodate 18-22 AWG
• Terminal Type: Must be flanged
• Termination Method: Must be crimp
• Contact Material: Must be copper, ETP
• Contact Finish: Must be tin
• Insulation: Must be insulated vinyl
• Insulation Diameter: Must be 0.145" (3.68mm)
• Color: Must be red
• Mounting Type: Must be free hanging (in-line)

The Keystone Electronics 8246 meets all critical substitution criteria. Dimensional variations in overall length (0.700" vs. 0.850") and ring center to termination length do not affect functional interchangeability when the stud interface, wire gauge accommodation, and contact geometry remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both the BS-21-8-P and Keystone Electronics 8246 are Active product status components with identical RoHS3 compliance and MSL 1 ratings. Selection between these parts should be based on availability, lead time, and application-specific space constraints. The 0.150" overall length difference between the two parts does not affect electrical performance or stud interface compatibility. Both parts maintain identical ring center to termination and termination length dimensions, ensuring consistent crimp performance and contact engagement. Compliance certifications (ECCN EAR99, HTSUS 8536.90.4000) are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8246 be used as a direct replacement for the BS-21-8-P?

A: Yes. Both parts share identical stud size (#8), wire gauge (18-22 AWG), contact material (copper ETP), contact finish (tin), insulation type (vinyl), and insulation diameter (0.145"). The 0.150" difference in overall length does not affect functional interchangeability in standard applications.

Q: Does the shorter overall length of the 8246 affect crimp performance?

A: No. The critical dimensions for crimp performance—termination length (0.450"), ring center to termination (0.250"), and insulation diameter (0.145")—are identical between both parts. Overall length variation does not impact wire termination quality or stud engagement.

Q: Are both parts RoHS compliant?

A: Yes. Both the BS-21-8-P and 8246 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What determines substitution eligibility for #8 red spade terminals?

A: Substitution requires matching stud size (#8), wire gauge (18-22 AWG), terminal type (flanged), termination method (crimp), contact material (copper ETP), contact finish (tin), insulation type (vinyl), insulation diameter (0.145"), color (red), and mounting type (free hanging in-line). Dimensional variations outside these critical parameters do not affect interchangeability.

Q: Are there packaging differences between these parts?

A: The BS-21-8-P is supplied in bulk packaging. Keystone Electronics 8246 packaging information is not specified in the available data. Verify packaging requirements with your supplier for order fulfillment.
