Selection between these parts is based on inventory availability and procurement lead times, as all electrical, mechanical, and compliance specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the 0034.4225 be used as a direct replacement for the 0034.4255 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical ratings (2.5 A, 125 V AC/DC), mechanical specifications (through-hole radial mounting, 0.252" Dia x 0.346" H), response characteristics (fast blow), and regulatory certifications (cURus, ROHS3). No design modifications are required.

Q: Are there any differences in breaking capacity or melting I²t between these parts?

A: No. Both parts specify 100 A breaking capacity at rated voltage and 0.6 melting I²t, ensuring identical circuit protection performance.

Q: Do both parts operate within the same temperature range?

A: Yes. Both the 0034.4255 and 0034.4225 are rated for -25°C to 85°C operating temperature range.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical cURus approval agency certification and ROHS3 compliance status. REACH status is Unaffected for both components.

Q: What is the physical package difference, if any?

A: There is no physical package difference. Both parts use identical radial, can-style packaging with matching dimensions of 0.252" diameter by 0.346" height (6.40mm x 8.80mm).

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Since all parameters are identical, both parts can be used interchangeably within the same circuit board assembly without affecting performance or reliability.
