Substitute Part Grouping Explanation

Substitution eligibility for the BK/MAX-50ID is determined by strict equivalence across the following critical parameters:

• Current Rating: 50 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Fuse Type: Automotive (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: Blade, Max (exact match required)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• Physical Dimensions: 1.150" L x 0.350" W x 0.850" H (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute part MAX-50 meets all these criteria and is therefore classified as a parametric equivalent within the MAX series product line.

Parameter Comparison

Engineering Selection Recommendations

Both BK/MAX-50ID and MAX-50 are active production components from Eaton - Bussmann Electrical Division with identical electrical and mechanical specifications. The MAX-50 carries ROHS3 compliance designation, while the BK/MAX-50ID is RoHS Compliant. Both components satisfy automotive fuse requirements for 50A circuits at 32V DC with fast-blow response characteristics. Selection between these parts may be based on compliance requirements specific to the application or regional regulatory frameworks, as both maintain equivalent functional performance within automotive electrical systems.

Frequently Asked Questions (FAQ)

Q: Can MAX-50 be used as a direct replacement for BK/MAX-50ID?

A: Yes. Both parts are parametric equivalents with identical current ratings (50A), voltage ratings (32V DC), fuse type (automotive), response time (fast blow), package type (blade, max), breaking capacity (1kA), and physical dimensions. Both require a compatible fuse holder for installation.

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

A: Substitution requires exact matching of current rating (50A), DC voltage rating (32V), fuse type (automotive), response time (fast blow), package configuration (blade, max), breaking capacity (1kA), and physical dimensions (1.150" L x 0.350" W x 0.850" H). Deviation in any of these parameters disqualifies a part as a substitute.

Q: Are there differences in compliance certifications between these parts?

A: BK/MAX-50ID carries RoHS Compliant status, while MAX-50 carries ROHS3 Compliant status. Both are active production components. Application-specific compliance requirements should determine which part is appropriate for your system.

Q: What mounting considerations apply to these fuses?

A: Both BK/MAX-50ID and MAX-50 require a compatible blade fuse holder for installation. The MAX blade form factor is standardized, and both parts are physically identical in dimensions and mounting interface.

Q: Are these parts suitable for automotive applications?

A: Yes. Both parts are classified as automotive fuses with fast-blow response characteristics, designed for automotive electrical systems operating at 32V DC with circuit protection requirements up to 50A.
