Parameter Comparison

Engineering Selection Recommendations

The 0324008.MXP from Littelfuse Inc. is a direct electrical and mechanical substitute for the ABC-V-8-R. Both parts are active products with ROHS3 compliance certification. The substitute part carries additional international approvals (CE, K-MARK, PSE) beyond the original part's CSA and UL certifications, providing broader regulatory coverage. The substitute's higher AC breaking capacity (750 A versus 200 A) and expanded operating temperature range (-55°C to 125°C) represent enhanced performance characteristics that do not compromise compatibility. Both parts share identical voltage ratings, current ratings, package dimensions, and response time specifications required for direct circuit substitution.

Frequently Asked Questions (FAQ)

Q: Can the 0324008.MXP replace the ABC-V-8-R in all applications?

A: Yes. Both parts share identical electrical ratings (8 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), package format (3AB/3AG, 1/4" x 1-1/4"), response time (fast blow), and mounting configuration (through hole). Both are ROHS3 compliant and active products.

Q: What are the dimensional differences between these parts?

A: The ABC-V-8-R measures 0.266" diameter × 1.292" length (6.76 mm × 32.82 mm). The 0324008.MXP measures 0.275" diameter × 1.288" length (6.99 mm × 32.72 mm). These minor variations remain within the 3AB/3AG package specification tolerance and do not affect mechanical fit in standard through-hole fuse holders.

Q: Are there differences in breaking capacity?

A: The 0324008.MXP has a higher AC breaking capacity (750 A) compared to the ABC-V-8-R (200 A). Both maintain identical 10 kA DC breaking capacity. The higher AC rating on the substitute part does not create compatibility issues and represents enhanced performance margin.

Q: What certifications does each part carry?

A: The ABC-V-8-R carries CSA and UL approvals. The 0324008.MXP carries CE, CSA, K-MARK, PSE, and UL approvals. The substitute part's additional certifications provide broader international regulatory acceptance without affecting domestic application compatibility.

Q: How do the melting I²t values compare?

A: The ABC-V-8-R has a melting I²t of 116.5, while the 0324008.MXP has 105. Both values fall within acceptable tolerance for fast-blow ceramic cartridge fuses in this current and voltage class, ensuring equivalent thermal response characteristics.

Q: Are there inventory considerations?

A: The ABC-V-8-R has 732 pieces in stock. The 0324008.MXP has 4,100 pieces available, providing significantly greater supply availability for extended production runs or emergency sourcing requirements.
