Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GMD-150-R is determined by strict equivalence across the following critical parameters:

Current Rating: 150 mA (exact match required)

Voltage Rating (AC): 250 V (exact match required)

Fuse Type: Cartridge, Glass (exact match required)

Response Time: Slow Blow (exact match required)

Package / Case: 5mm x 20mm (exact match required)

Mounting Type: Requires Holder (exact match required)

Breaking Capacity @ Rated Voltage: 35A (exact match required)

The substitute part 0239.150MXP manufactured by Littelfuse meets all critical electrical and mechanical parameters. Both parts are ROHS3 compliant and carry UL approval. The substitute maintains identical current, voltage, fuse type, response characteristics, and physical dimensions, ensuring direct functional equivalence in applications designed for the BK/GMD-150-R.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/GMD-150-R and 0239.150MXP are active products with current manufacturing status. The BK/GMD-150-R carries CSA and UL approvals, while the 0239.150MXP carries CE and UL approvals.

Frequently Asked Questions (FAQ)

Q: Can the 0239.150MXP directly replace the BK/GMD-150-R in existing applications?

A: Yes, the 0239.150MXP is electrically and mechanically equivalent to the BK/GMD-150-R. Both parts share identical current rating (150 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (slow blow), and physical dimensions (5mm x 20mm). Both require a compatible fuse holder and deliver 35A breaking capacity at rated voltage.

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

A: The BK/GMD-150-R carries CSA and UL approvals. The 0239.150MXP carries CE and UL approvals. Both parts are UL approved. Applications requiring specific regional certifications should verify compliance requirements before substitution.

Q: Do these fuses require a specific holder type?

A: Both the BK/GMD-150-R and 0239.150MXP are cartridge fuses with 5mm x 20mm dimensions and require a dedicated fuse holder designed for this form factor. The fuse holder must be compatible with 5mm x 20mm cartridge fuses.

Q: What is the difference in melting I²t values between these parts?

A: The BK/GMD-150-R has a melting I²t of 0.046, while the 0239.150MXP has a melting I²t of 0.13. Both parts are classified as slow-blow fuses and deliver the same 150 mA current rating and 35A breaking capacity at rated voltage.

Q: Are both parts RoHS compliant?

A: Yes, both the BK/GMD-150-R and 0239.150MXP are ROHS3 compliant.
