CH142B-PV Equivalent & Substitute Parts

Part Overview

The CH142B-PV is a 2-pole fuse holder manufactured by Eaton - Bussmann Electrical Division, designed for 32 A at 1500V operation with cartridge-type fuses in a 14mm x 51mm form factor. This component is mounted on DIN rail with vertical orientation and screw terminal connections. The CH142B-PV is classified as obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CH142B-PV is based on the following critical parameters that must remain consistent:

• Mechanical Compatibility: Fuse size (14mm x 51mm cartridge), DIN rail mounting, vertical orientation, and screw terminal connection
• Electrical Architecture: 2-pole circuit configuration and cartridge fuse type
• Form Factor: Same physical dimensions and mounting interface

The substitute part CHPV142U maintains identical mechanical specifications and circuit configuration. However, the substitute operates at different electrical ratings: 50 A current capacity and 700V voltage rating, compared to the original 32 A at 1500V. These electrical parameter differences must be evaluated against the specific application requirements before substitution.

Parameter Comparison

Engineering Selection Recommendations

The CHPV142U is the active production substitute for the obsolete CH142B-PV within the Eaton - Bussmann CH series. Both components share identical mechanical specifications, mounting interface, and 2-pole circuit architecture, enabling direct physical replacement in DIN rail installations.

The CHPV142U carries RoHS compliance certification, whereas the original CH142B-PV does not specify compliance status. This compliance advantage supports deployment in applications subject to RoHS regulatory requirements.

Component selection must account for the electrical rating differences. The CHPV142U operates at 50 A and 700V, while the CH142B-PV was rated for 32 A and 1500V. Application circuits must operate within the electrical envelope of the selected component. The lower voltage rating of the substitute (700V versus 1500V) and higher current capacity (50 A versus 32 A) require verification against system design specifications.

Frequently Asked Questions (FAQ)

Q: Can CHPV142U physically replace CH142B-PV in existing installations?

A: Yes. Both components use identical 14mm x 51mm cartridge fuses, DIN rail mounting, vertical orientation, and screw terminal connections. Physical installation compatibility is confirmed.

Q: What are the electrical differences between these components?

A: The CH142B-PV operates at 32 A and 1500V. The CHPV142U operates at 50 A and 700V. These ratings must be compatible with the application circuit before substitution.

Q: Why does the substitute have different electrical ratings?

A: The CHPV142U is optimized for photovoltaic applications, as indicated by its part designation. Different application requirements drive different electrical specifications within the same mechanical form factor.

Q: Is the CHPV142U RoHS compliant?

A: Yes. The CHPV142U carries RoHS compliance certification. The original CH142B-PV does not specify RoHS status.

Q: Are there inventory considerations for these parts?

A: The CH142B-PV (obsolete status) has 1035 pieces in stock. The CHPV142U (active status) has 1073 pieces in stock. Active production status of the substitute ensures long-term availability.

Q: What is the primary application difference between these fuse holders?

A: The CH142B-PV is a general-purpose 2-pole fuse holder. The CHPV142U is specifically designed for photovoltaic systems, as reflected in its product designation and electrical specifications.
