Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/MAX-30ID are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Current Rating: 30 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)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: 1.150" L x 0.350" W x 0.850" H (exact match required)

Only parts meeting all these parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX-30 is a direct parametric equivalent to the BK/MAX-30ID. Both parts are manufactured by Eaton - Bussmann Electrical Division within the MAX series and share identical electrical specifications, mechanical dimensions, and compliance certifications. Both parts maintain active product status and RoHS compliance.

Selection between BK/MAX-30ID and MAX-30 should be based on inventory availability and procurement lead times. The BK/MAX-30ID currently has higher stock availability (1112 units) compared to MAX-30 (866 units).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are identical in all critical parameters: 30A current rating, 32V DC voltage rating, fast-blow response time, Blade Max package, 1kA breaking capacity, and physical dimensions. Both are RoHS compliant and manufactured by Eaton - Bussmann Electrical Division.

Q: Are there any differences in performance between BK/MAX-30ID and MAX-30?

A: No. The parts are electrically and mechanically equivalent with identical breaking capacity, response characteristics, and voltage/current ratings.

Q: What is the significance of the "Blade, Max" package designation?

A: The Blade, Max package specifies the physical form factor and holder compatibility. Both substitute parts use this identical package type, ensuring mechanical interchangeability in automotive fuse holders designed for MAX-series blade fuses.

Q: Does the color designation (Green) affect substitution?

A: No. Color is a visual indicator of the 30A rating in automotive fuse standards but does not affect electrical performance or substitution eligibility.

Q: What mounting considerations apply to these fuses?

A: Both parts require a dedicated fuse holder for installation. They are not soldered directly to circuit boards. Ensure the target application uses a compatible MAX-series blade fuse holder.
