Substitute Part Grouping Explanation

Substitute parts for the BK/MAX-30 are identified through strict parametric matching across the following critical specifications:

• Current Rating: 30 A
• Voltage Rating - DC: 32 V
• Fuse Type: Automotive
• Package / Case: Blade, Max
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 1 kA
• Mounting Type: Requires Holder

Only components matching all these parameters across electrical and mechanical dimensions are classified as direct substitutes. This ensures functional equivalence and compatibility within automotive electrical protection circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/MAX-30 and MAX-30 maintain Active product status with full RoHS compliance certification. Selection between these components should be based on inventory availability and supply chain requirements. The MAX-30 substitute currently maintains 866 units in stock compared to 748 units for the primary BK/MAX-30 part number. Both components are manufactured by the same supplier and carry identical electrical and mechanical specifications, ensuring interchangeability in automotive fuse holder applications rated for 30A at 32V DC operation.

Frequently Asked Questions (FAQ)

Q: Can MAX-30 be used as a direct replacement for BK/MAX-30?

A: Yes. Both components share identical electrical ratings (30A, 32V DC), mechanical form factor (Blade, Max), response characteristics (Fast Blow), and breaking capacity (1 kA). They are functionally equivalent for automotive fuse applications.

Q: What determines if a fuse is a valid substitute?

A: Valid substitutes must match all critical parameters: current rating, voltage rating, fuse type, package form factor, response time, breaking capacity, and mounting requirements. Deviations in any parameter disqualify a component from substitution.

Q: Are there any compliance differences between these parts?

A: No. Both the BK/MAX-30 and MAX-30 carry identical RoHS compliance status and are manufactured by Eaton - Bussmann Electrical Division under the same MAX series specification.

Q: What is the physical compatibility consideration?

A: Both components feature identical dimensions (1.150" L x 0.350" W x 0.850" H) and require the same MAX-series fuse holder. Physical installation compatibility is assured.

Q: Does response time affect substitution eligibility?

A: Yes. Both components feature Fast Blow response characteristics. Substitutes with different response times (such as Slow Blow or Medium Blow) are not equivalent and cannot be used interchangeably in circuits designed for fast-blow protection.
