Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSA 8-R is determined by strict alignment with the following core parameters: current rating (8 A), voltage rating (250 V AC), fuse type (cartridge ceramic), response time (slow blow), package configuration (3AB, 3AG, 1/4" x 1-1/4"), and mounting requirement (holder-based). All identified substitutes meet these mandatory criteria, ensuring mechanical and electrical compatibility within the specified operating temperature range (-55°C ~ 125°C) and regulatory compliance framework (ROHS3, REACH Unaffected, EAR99).

Parameter Comparison

Engineering Selection Recommendations

All three parts—GSA 8-R, 0326008.MXP, and TCA-8A—maintain active product status and full compliance with ROHS3 and REACH requirements. Selection among these substitutes should be based on approval agency certifications relevant to the end application. The GSA 8-R and TCA-8A carry CE, CSA, and PSE certifications, with TCA-8A additionally certified to UL 248. The 0326008.MXP from Littelfuse includes K-MARK certification in addition to CE, CSA, PSE, and UL approvals, providing the broadest regulatory coverage. Dimensional tolerances are consistent across all three parts, with the 0326008.MXP showing a nominal length of 31.75mm compared to 31.80mm for the other two, a difference within standard mechanical compatibility for holder-based mounting systems.

Frequently Asked Questions (FAQ)

Q: Can 0326008.MXP be used as a direct replacement for GSA 8-R?

A: Yes. Both parts share identical electrical specifications (8 A, 250 V AC, slow-blow ceramic cartridge), package configuration (3AB, 3AG, 1/4" x 1-1/4"), and operating temperature range (-55°C ~ 125°C). Dimensional variance of 0.05mm in length is within mechanical tolerance for holder-based systems.

Q: What is the difference between GSA 8-R and TCA-8A?

A: Both parts are electrically and mechanically equivalent with matching current, voltage, fuse type, response time, and package specifications. The primary difference is manufacturer (Bel Fuse vs. OptiFuse) and approval agency certifications. TCA-8A includes UL 248 certification, while GSA 8-R carries CE, CSA, and PSE approvals.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are GSA 8-R (1343 units), 0326008.MXP (2620 units), and TCA-8A (9103 units). Substitute selection may be influenced by availability and procurement lead times.

Q: Does the breaking capacity difference between parts affect substitution?

A: Breaking capacity values (GSA 8-R: 200A, 0326008.MXP: 400A, TCA-8A: 200A) are provided specifications. Selection should confirm that the chosen part's breaking capacity meets or exceeds the application requirement.

Q: What holder types are compatible with these fuses?

A: All three parts require 3AB or 3AG holder configurations. Verify that existing holder hardware is rated for these standard configurations before substitution.
