Frequently Asked Questions (FAQ)

Q: Can the 0326.200MXP be used as a direct replacement for the GSA 200-R?

A: Yes. Both parts share identical current rating (200 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), and package form factor (3AB, 3AG, 1/4" x 1-1/4"). The parts are mechanically and electrically compatible within the specified parameters.

Q: What is the primary reason for substitution?

A: The GSA 200-R is classified as obsolete. The 0326.200MXP is an active product from Littelfuse Inc., ensuring reliable procurement and continued availability.

Q: Are there any compatibility concerns with existing holders?

A: No. Both parts use the same 3AB and 3AG holder requirements with identical physical dimensions (0.250" Dia x 1.25" L nominal). Existing holders designed for the GSA 200-R will accommodate the 0326.200MXP without modification.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected. The GSA 200-R carries CE, CSA, and cULus approvals, while the 0326.200MXP carries CE approval. Verify specific certification requirements for your application.

Q: Are there differences in electrical characteristics?

A: Both parts are rated for identical current and voltage parameters. Minor variations exist in breaking capacity and melting I²t values; however, these do not affect substitution eligibility within the specified parameter set for this product category.
