• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

Mechanical Equivalence:

• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Equivalence:

• RoHS Status: RoHS Compliant or equivalent environmental standard
• Approval Agencies: Minimum overlap with CSA, PSE, or UL certifications

The substitute part 0235.100MXEP from Littelfuse Inc. meets all electrical and mechanical equivalence criteria and maintains regulatory compliance through recognized approval agencies.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: BK/GMA-V-100-R

The BK/GMA-V-100-R remains the specified component for original design implementations. It carries active product status with established certifications from CSA, PSE, and UL. Current inventory of 712 units supports standard procurement cycles.

Substitute Part: 0235.100MXEP

The 0235.100MXEP from Littelfuse Inc. is electrically and mechanically equivalent and qualifies as a direct substitute. Both parts share identical current rating (100 mA), voltage rating (250 V AC), response time (Fast Blow), breaking capacity (35 A), and package format (5mm x 20mm axial through-hole). Both maintain active product status and RoHS compliance. The substitute carries broader regulatory approval (CE, CSA, KC, UL) and higher inventory availability (3028 units), supporting extended supply chain flexibility. Physical dimensions show minor variation within acceptable tolerance for through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can 0235.100MXEP be used as a direct replacement for BK/GMA-V-100-R?

A: Yes. Both parts are electrically equivalent with identical current rating (100 mA), voltage rating (250 V AC), response time (Fast Blow), and breaking capacity (35 A). Both are glass cartridge fuses in 5mm x 20mm axial through-hole packages. Mechanical dimensions show minor variation (diameter 5.54mm vs. 6.00mm, length 21.10mm vs. 22.50mm) within acceptable tolerance for standard through-hole PCB mounting.

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

A: Substitution is determined by exact equivalence in: current rating (100 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), breaking capacity (35 A), package format (5mm x 20mm axial), and mounting type (through-hole). Regulatory compliance through recognized approval agencies (CSA, UL, or equivalent) is required.

Q: Are there compliance differences between the two parts?

A: Both parts maintain RoHS compliance. BK/GMA-V-100-R carries CSA, PSE, and UL approvals. 0235.100MXEP carries CE, CSA, KC, and UL approvals. Both meet the regulatory requirements for their respective markets. Application-specific compliance requirements should be verified against regional standards.

Q: What is the difference in melting I²t values?

A: BK/GMA-V-100-R has a melting I²t of 0.0001, while 0235.100MXEP has 0.00312. Both are fast-blow fuses with identical current and voltage ratings. The I²t value reflects the thermal energy required to melt the fuse element. Despite this difference, both parts meet the 35 A breaking capacity specification at rated voltage and are classified as fast-blow response types.

Q: Are the physical dimensions interchangeable?

A: Both parts use the 5mm x 20mm axial package format for through-hole mounting. Measured dimensions show minor variation: BK/GMA-V-100-R is 5.54mm diameter x 21.10mm length; 0235.100MXEP is 6.00mm diameter x 22.50mm length. These variations are within acceptable tolerance for standard through-hole fuse holders and PCB mounting applications.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain requirements and regional compliance needs. BK/GMA-V-100-R is the original specification. 0235.100MXEP offers higher inventory availability and broader regulatory approval coverage (CE, CSA, KC, UL). Both are active products suitable for production use.
