CBPW-25 Equivalent & Substitute Parts

Part Overview

The CBPW-25 is a 25-circuit barrier block connector manufactured by Curtis Industries, designed for panel and chassis mounting applications. This terminal block features a 0.375" (9.53mm) pitch with screw termination and captive plate design, rated for 20A at 300V with wire gauge compatibility of 12-22 AWG. The component is actively produced and maintains full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the CBPW-25 is determined by strict equivalence across the following critical parameters:

Circuit Configuration: 25 circuits with 0.375" (9.53mm) pitch
Electrical Ratings: 20A current rating and 300V voltage rating
Termination Style: Screw termination with captive plate (top) and PC pin (bottom)
Barrier Configuration: 2 Wall (Dual) barrier type
Wire Compatibility: 12-22 AWG wire gauge acceptance
Mounting Interface: Through hole PC pin termination
Regulatory Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The substitute part 5-796985-1 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters required for direct substitution in applications where the CBPW-25 is specified.

Engineering Selection Recommendations

Both the CBPW-25 and 5-796985-1 are active products with full regulatory compliance. Selection between these parts should be based on the following factors:

CBPW-25 (Curtis Industries): Suitable for applications requiring maximum operating temperature tolerance up to 140°C. Insulation material specified as Polyester Thermoplastic.

5-796985-1 (TE Connectivity AMP Connectors): Suitable for applications with operating temperature requirements up to 105°C. Insulation material specified as Thermoplastic. Terminal screw material is Steel with Zinc, Clear Chromate finish. Higher inventory availability (2015 pcs vs. 981 pcs) may support shorter lead times.

Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements. Selection should account for application-specific temperature requirements and procurement lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can 5-796985-1 be used as a direct replacement for CBPW-25?

A: Yes, for applications with operating temperatures up to 105°C. The 5-796985-1 meets all critical electrical and mechanical parameters: 25 circuits, 0.375" pitch, 20A rating, 300V rating, screw termination with captive plate, and dual-wall barrier configuration. If your application requires operation above 105°C, the CBPW-25 is specified for 140°C operation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in circuit count (25), pitch spacing (0.375"), electrical ratings (20A/300V), termination style (screw with captive plate), barrier type (dual wall), wire gauge acceptance (12-22 AWG), and regulatory compliance (UL94 V-0, ROHS3).

Q: Are there differences in terminal screw specifications between these parts?

A: Yes. The CBPW-25 does not specify terminal screw material or finish. The 5-796985-1 specifies Steel terminal screws with Zinc, Clear Chromate finish. Both parts use identical screw termination with captive plate design.

Q: What is the difference in operating temperature ratings?

A: The CBPW-25 is rated for 140°C maximum operating temperature, while the 5-796985-1 is rated for 105°C. For applications exceeding 105°C, the CBPW-25 is the appropriate selection.

Q: Do both parts have the same insulation material?

A: Both use thermoplastic insulation materials. The CBPW-25 specifies Polyester Thermoplastic, while the 5-796985-1 specifies Thermoplastic without material type specification.

Q: Are both parts RoHS compliant?

A: Yes, both the CBPW-25 and 5-796985-1 are ROHS3 compliant and carry UL94 V-0 flammability ratings.
