Key Parameters

Substitute Part Grouping Explanation

Substitution of the GSAP 8-R is determined by strict equivalence across the following parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Ceramic cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG form factor (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

The substitute part 0325008.MXP manufactured by Littelfuse Inc. meets all mandatory electrical and mechanical parameters for direct substitution. Both parts share identical current, voltage, response characteristics, and physical package specifications, enabling interchangeable use in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The 0325008.MXP from Littelfuse Inc. is the direct equivalent substitute for the obsolete GSAP 8-R. Selection is based on the following engineering criteria:

• Electrical equivalence: Identical 8A, 250V AC ratings and slow-blow response characteristics
• Mechanical compatibility: Matching 3AB/3AG package format and through-hole mounting configuration
• Regulatory compliance: Both parts hold CE, CSA, and PSE certifications; the substitute additionally carries K-MARK and UL approvals
• Environmental compliance: Both parts are ROHS3 compliant and REACH unaffected
• Product availability: The substitute is in active production status with confirmed inventory, ensuring long-term supply continuity

Physical dimensions show negligible variation (0.003" diameter and 0.008" length differences) within acceptable manufacturing tolerances for 3AB/3AG cartridge fuses, confirming mechanical interchangeability in standard fuse holders.

Frequently Asked Questions (FAQ)

Q: Can the 0325008.MXP be used as a direct replacement for GSAP 8-R in existing designs?

A: Yes. Both parts share identical electrical ratings (8A, 250V AC), fuse type (ceramic cartridge), response time (slow blow), and package format (3AB/3AG). Physical dimensions are within acceptable manufacturing tolerances for this package class.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Bel Fuse Inc. vs. Littelfuse Inc.) and product status (obsolete vs. active). The substitute has higher breaking capacity (400A vs. 200A) and different melting I²t values (67.1 vs. 483), but these do not affect substitution eligibility as they represent enhanced performance characteristics. The substitute also carries additional certifications (K-MARK, UL).

Q: Are there any compatibility concerns with the slight dimensional variations?

A: No. The dimensional differences (0.003" diameter, 0.008" length) are within standard manufacturing tolerances for 3AB/3AG cartridge fuses and do not affect fit or function in standard fuse holders.

Q: What certifications apply to both parts?

A: Both parts hold CE, CSA, and PSE certifications. The substitute additionally carries K-MARK and UL approvals, providing broader regulatory coverage.

Q: Is the substitute part currently available?

A: Yes. The 0325008.MXP is in active production status with confirmed inventory availability, ensuring reliable supply for new designs and replacements.
