• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.142" Dia x 0.394" L (3.60mm x 10.00mm) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part 0874004.MXEP meets all critical electrical and mechanical parameters, maintaining functional equivalence for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0876004.MXEP and 0874004.MXEP maintain Active product status with full regulatory compliance. The 0876004.MXEP carries dual certification (cULus and VDE), while the 0874004.MXEP carries cULus certification. Selection between these parts should be based on specific circuit protection requirements and regional compliance mandates. The substitute part 0874004.MXEP demonstrates higher breaking capacity (50A versus 40A) and lower melting I²t (10.03 versus 14.64), indicating faster response characteristics under fault conditions. Both parts satisfy ROHS3 compliance and identical electrical ratings for standard 4A 250VAC applications.

Frequently Asked Questions (FAQ)

Q: Can 0874004.MXEP be used as a direct replacement for 0876004.MXEP?

A: Yes. Both parts share identical current rating (4A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (fast blow), mounting configuration (through hole axial), physical dimensions (0.142" Dia x 0.394" L), and operating temperature range (-55°C ~ 125°C). Functional equivalence is maintained for circuit protection applications.

Q: What are the differences between these two fuses?

A: The primary differences are breaking capacity (0874004.MXEP: 50A versus 0876004.MXEP: 40A), melting I²t (0874004.MXEP: 10.03 versus 0876004.MXEP: 14.64), DC cold resistance (0874004.MXEP: 0.0195 Ohms versus 0876004.MXEP: 0.0149 Ohms), and approval certifications (0874004.MXEP: cULus only versus 0876004.MXEP: cULus and VDE).

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. Current inventory levels differ: 0876004.MXEP has 1323 pieces in stock, while 0874004.MXEP has 2307 pieces in stock.

Q: Do these fuses meet environmental and regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected. The 0876004.MXEP carries VDE certification in addition to cULus approval, providing broader regional compliance coverage.
