Frequently Asked Questions (FAQ)

Q: Can 0253015.M be used as a direct replacement for 0253015.V?

A: Yes. Both parts are parametrically equivalent with identical electrical ratings (15A, 32V AC/DC), response characteristics (Fast Blow), physical dimensions (0.103" Dia x 0.280" L), and regulatory approvals. No circuit redesign or PCB modification is required.

Q: Are there any differences in breaking capacity between these parts?

A: No. Both parts have identical breaking capacity ratings of 50A AC and 300A DC at rated voltage.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 0253015.V and 0253015.M carry CSA, QPL, and UR approvals, are ROHS3 compliant, and have REACH Unaffected status.

Q: What is the difference between the .V and .M designations?

A: The suffix designations (.V and .M) indicate different packaging or distribution variants within the same electrical and mechanical specification. All critical parameters remain identical.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical through-hole axial mounting configuration, lead spacing, and physical dimensions ensure direct PCB compatibility without layout modifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C, providing consistent thermal performance across the full temperature spectrum.
