Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSAP 200-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)

The Littelfuse 0325.200MXP meets all substitution criteria. Both parts share identical electrical ratings, form factors, and response characteristics, enabling direct functional replacement in applications designed for the GSAP 200-R.

Parameter Comparison

Engineering Selection Recommendations

The 0325.200MXP from Littelfuse is a direct functional equivalent to the obsolete GSAP 200-R. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Littelfuse part carries active product status, ensuring ongoing availability and supply chain continuity.

Dimensional tolerances between the two parts are within acceptable mechanical limits for standard 3AB, 3AG cartridge fuse holders. The DC cold resistance differential (7.1 Ohms versus 6.77 Ohms) is negligible for circuit protection applications and does not affect functional performance in the specified voltage and current ratings.

The 0325.200MXP is approved under CE standards, consistent with the multi-agency approvals (CE, CSA, cULus) of the original GSAP 200-R. Selection of the Littelfuse substitute ensures compliance with current component qualification standards while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0325.200MXP be used as a direct replacement for the GSAP 200-R?

A: Yes. Both parts are 200 mA, 250 V AC/DC ceramic cartridge fuses in the 3AB, 3AG form factor with slow-blow response. They are mechanically and electrically interchangeable in applications designed for the GSAP 200-R.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The GSAP 200-R is obsolete, meaning Bel Fuse Inc. no longer manufactures or supports this part. The 0325.200MXP is active, ensuring long-term availability, technical support, and supply chain reliability for new designs and ongoing maintenance applications.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The GSAP 200-R carries CE, CSA, and cULus approvals, while the 0325.200MXP carries CE approval. For applications requiring CSA or cULus certification, verification against specific system requirements is necessary.

Q: Do the dimensional differences affect mechanical fit?

A: The dimensional variations (0.272" vs. 0.275" diameter; 1.280" vs. 1.288" length) are within standard tolerances for 3AB, 3AG cartridge fuse holders and do not affect mechanical compatibility or electrical performance.

Q: What is the impact of the DC cold resistance difference?

A: The DC cold resistance values (7.1 Ohms vs. 6.77 Ohms) are functionally equivalent for circuit protection applications. This minor difference does not affect fuse operation at the specified 200 mA, 250 V ratings.
