CBP-25 Equivalent & Substitute Parts Reference

Part Overview

The CBP-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 dual-wall barrier construction and screw termination on the top side with PC pin connections on the bottom. The part is currently active in production with 829 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category, enabling direct functional replacement in applications where the main part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 5-796985-1 qualifies as a substitute for the CBP-25 based on the following critical parameters:

Electrical Compatibility:

• Identical circuit count: 25 circuits
• Identical pitch: 0.375" (9.53mm)
• Identical current rating: 20A
• Identical voltage rating: 300V
• Identical wire gauge acceptance: 12-22 AWG

Mechanical Compatibility:

• Identical barrier block type with dual-wall (2 Wall) construction
• Identical bottom termination: PC Pin
• Identical number of rows: 1
• Identical color: Black
• Identical terminal screw material: Steel

Regulatory Compliance:

• Identical flammability rating: UL94 V-0
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

The primary difference is the top termination design: the CBP-25 uses standard screws, while the 5-796985-1 incorporates a captive plate screw design. This variation does not affect electrical or mechanical substitution capability in applications where the connector is mounted to a panel or chassis.

Parameter Comparison

Engineering Selection Recommendations

Both the CBP-25 and 5-796985-1 maintain active product status with full regulatory compliance. The CBP-25 is currently available with 829 units in stock, while the 5-796985-1 has higher inventory availability at 2015 units.

Selection between these parts should be based on:

CBP-25 (Curtis Industries): Primary choice when standard screw termination is specified and Curtis Industries sourcing is preferred. Suitable for applications with standard panel-mount screw assembly procedures.

5-796985-1 (TE Connectivity): Suitable alternative when captive plate screw design is acceptable or preferred. The captive plate feature may provide operational advantages in applications requiring frequent connector maintenance or where screw retention is critical. Higher inventory availability supports shorter lead times.

Both parts satisfy identical electrical load requirements (20A at 300V), mechanical mounting specifications, and regulatory requirements (UL94 V-0, ROHS3 compliance). Operating temperature differs between the parts (CBP-25 rated to 140°C versus 5-796985-1 rated to 105°C); application thermal requirements must be evaluated accordingly.

Frequently Asked Questions (FAQ)

Q: Can the 5-796985-1 directly replace the CBP-25 in existing designs?

A: Yes, for applications where the operating temperature does not exceed 105°C. The 5-796985-1 maintains identical electrical ratings (20A, 300V), circuit count (25), pitch (0.375"), wire gauge acceptance (12-22 AWG), and barrier construction (dual-wall). The captive plate screw design is mechanically compatible with standard panel-mount installations.

Q: What is the difference between standard screws and captive plate screws?

A: Standard screws (CBP-25) are loose fasteners that must be individually managed during assembly. Captive plate screws (5-796985-1) are retained to the connector body, reducing the risk of screw loss during handling and installation. Both designs provide equivalent electrical and mechanical connection integrity.

Q: Are there operating temperature limitations when substituting?

A: Yes. The CBP-25 is rated to 140°C, while the 5-796985-1 is rated to 105°C. If the application requires operation above 105°C, the CBP-25 must be used. For applications operating at or below 105°C, both parts are equivalent.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CBP-25 and 5-796985-1 are UL94 V-0 rated, ROHS3 compliant, and carry MSL 1 (Unlimited) ratings. Regulatory compliance is equivalent across both parts.

Q: What is the pitch specification and why is it important?

A: Pitch is the center-to-center distance between adjacent circuits, specified as 0.375" (9.53mm) for both parts. Pitch determines physical spacing and is critical for PCB layout compatibility. Both parts share identical pitch, ensuring mechanical interchangeability in the same mounting footprint.

Q: Can these parts accept the same wire gauge?

A: Yes. Both the CBP-25 and 5-796985-1 accept wire gauges from 12 to 22 AWG, providing equivalent wire termination flexibility.
