Frequently Asked Questions (FAQ)

Q: Can 0695025.U be used as a direct replacement for MCAS025.XP?

A: Yes. Both parts share identical current rating (25A), voltage rating (32V DC), response time (Slow Blow), fuse type (Automotive), package configuration (Auto Link), breaking capacity (1kA), operating temperature range (-40°C ~ 125°C), and physical dimensions (0.421" L x 0.244" W x 0.689" H). Both are ROHS3 compliant and REACH unaffected.

Q: Are there differences in the series designation between these parts?

A: MCAS025.XP belongs to the MCASE™ series, while 0695025.U belongs to the MCASE™ 695 series. Both series are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications for this 25A automotive fuse application.

Q: What is the Auto Link package configuration?

A: Auto Link is the package and mounting specification for this fuse type. Both substitute parts use identical Auto Link packaging, requiring a compatible fuse holder for installation.

Q: Are both parts suitable for -40°C to 125°C operating environments?

A: Yes. Both MCAS025.XP and 0695025.U are rated for the same operating temperature range of -40°C to 125°C, making them suitable for automotive applications across this thermal spectrum.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 1kA at rated voltage (32V DC), indicating the maximum fault current the fuse can safely interrupt.
