BC6031B Fuse Block Cartridge 600V 30A Chassis Mount - Equivalent & Substitute Parts

Part Overview

The BC6031B is a single-circuit cartridge fuse block rated for 600V at 30A, designed for chassis mount applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and system continuity. The BC6031B accepts Class CC fuses in the 10mm x 38mm (0.394" Dia x 1.496" L) form factor with solder lug termination and bronze tin-finished contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BC6031B is determined by the following critical parameters: current rating (30A), voltage rating (600V), fuse type (cartridge), fuse size (10mm x 38mm), number of circuits (1), and compatible fuse class. Two substitute parts meet these core electrical requirements:

BCM603-1C (Direct Manufacturer Substitute): Manufactured by Eaton - Bussmann Electrical Division, this part maintains identical electrical specifications (30A, 600V, 1-circuit cartridge block) and is currently in active production status. The BCM603-1C is RoHS compliant and represents the direct successor within the Eaton product line.

L60030C1C (Cross-Manufacturer Substitute): Manufactured by Littelfuse, this part matches all critical electrical parameters (30A, 600V, 1-circuit cartridge block, 10mm x 38mm fuse size) and is actively produced. The primary mechanical difference is mounting type (DIN Rail vs. Chassis Mount) and termination style (Box Lug vs. Solder Lug), which may require mechanical adaptation depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

BCM603-1C is the primary substitute for new designs and direct replacements. As an active product from the original manufacturer (Eaton - Bussmann), it provides continuity of supply, RoHS compliance, and identical electrical performance. This part is recommended when chassis mount configuration and solder lug termination are required.

L60030C1C serves as a secondary cross-manufacturer alternative when BCM603-1C availability is constrained. This Littelfuse product meets all core electrical specifications and holds ROHS3 compliance. Selection of this part requires verification that DIN Rail mounting and Box Lug termination are compatible with the target application's mechanical and electrical interface requirements.

Both substitute parts are classified as active products with current inventory availability, ensuring supply chain continuity for the obsolete BC6031B.

Frequently Asked Questions (FAQ)

Q: Can BCM603-1C directly replace BC6031B without modification? A: BCM603-1C matches all specified electrical parameters (30A, 600V, 1-circuit cartridge). Mechanical compatibility depends on mounting interface and termination requirements of the specific application.

Q: What is the primary difference between BCM603-1C and L60030C1C? A: BCM603-1C is manufactured by Eaton (original manufacturer) with unspecified mounting and termination details. L60030C1C is a Littelfuse product with DIN Rail mounting and Box Lug termination, differing from the BC6031B's Chassis Mount and Solder Lug configuration.

Q: Are both substitutes RoHS compliant? A: Yes. BCM603-1C is RoHS Compliant. L60030C1C is ROHS3 Compliant, meeting current regulatory requirements.

Q: What fuse types are compatible with these blocks? A: BC6031B is specified for Class CC fuses in 13/32" x 1-1/2" form factor. L60030C1C is specified for 5AG fuses in 13/32" x 1-1/2" form factor. Verify fuse class compatibility with your application requirements.

Q: Why is BC6031B classified as obsolete? A: Obsolete status indicates the part is no longer manufactured by Eaton - Bussmann. BCM603-1C and L60030C1C represent active alternatives for continued system support.
