BS-33-10 Equivalent & Substitute Parts

Part Overview

The BS-33-10 is a 10 stud spade terminal connector manufactured by 3M, designed for crimp termination of 10-12 AWG wire. This non-insulated terminal features a tin contact finish on ETP copper material and is configured as a free-hanging in-line connector. The part is Active in product status and ROHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring compatible 10-12 AWG spade terminal connectors with matching stud configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BS-33-10 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Stud/Tab Size: 10 Stud (electrical interface requirement)
• Wire Gauge: 10-12 AWG (termination capacity)
• Termination Method: Crimp (assembly process compatibility)
• Contact Material: Copper, ETP (electrical conductivity and corrosion resistance)
• Contact Finish: Tin (surface protection and solderability)
• Insulation Status: Non-Insulated (form factor and application context)
• Mounting Configuration: Free Hanging (In-Line) (mechanical installation method)
• Regulatory Compliance: ROHS3 Compliant (environmental and legal requirements)

Two substitute parts meet these criteria: Keystone Electronics 8226 and Panduit Corp P10-10F-L. Both maintain identical stud size, wire gauge, termination method, contact material, contact finish, and regulatory compliance. Dimensional variations exist in outer width and overall length; however, these do not affect electrical compatibility or stud interface performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BS-33-10, 8226, and P10-10F-L—are Active in product status and ROHS3 compliant, meeting current regulatory requirements. The BS-33-10 and 8226 are dimensionally identical in outer width and overall length, providing direct form-factor compatibility. The P10-10F-L exhibits slightly larger outer dimensions (0.370" width, 0.780" length) but maintains electrical compatibility through identical stud size, wire gauge, and contact specifications. Selection between these parts should be based on availability, procurement lead time, and mechanical space constraints within the application assembly. All three parts support 10-12 AWG crimp termination and tin-plated copper contact interfaces suitable for standard electrical connector applications.

Frequently Asked Questions (FAQ)

Q: Can P10-10F-L be used as a direct replacement for BS-33-10 despite dimensional differences?

A: Yes. The P10-10F-L maintains electrical compatibility through identical 10 stud size, 10-12 AWG wire gauge capacity, tin contact finish, and copper contact material. The dimensional increase (0.370" width vs. 0.320", 0.780" length vs. 0.730") does not affect the stud interface or electrical performance. Mechanical space availability in the application assembly must be confirmed.

Q: What is the significance of the butted seam versus brazed seam construction?

A: Both construction methods provide structural integrity for the terminal connector. The BS-33-10 features a butted seam, while the P10-10F-L features a brazed seam with serrated termination. These are manufacturing variations that do not affect electrical compatibility or stud interface performance.

Q: Are all three parts suitable for the same wire gauge range?

A: Yes. BS-33-10, 8226, and P10-10F-L all support 10-12 AWG wire termination through crimp assembly.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, restricting specific hazardous materials in electrical and electronic equipment. All three parts meet this regulatory requirement.

Q: Does MSL rating affect substitution compatibility?

A: MSL (Moisture Sensitivity Level) rating indicates moisture exposure risk during storage and handling. BS-33-10 and 8226 are rated MSL 1 (Unlimited), indicating no moisture sensitivity. P10-10F-L is rated Not Applicable. This does not affect electrical or mechanical compatibility but may influence storage and handling procedures based on application requirements.
