GSAP 7-R Equivalent & Substitute Parts

Part Overview

The GSAP 7-R is a 7A 250VAC ceramic cartridge fuse manufactured by Bel Fuse Inc., designed for Through Hole mounting in 3AB, 3AG form factor applications. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and design updates. The slow-blow response characteristic and ceramic construction provide protection in circuits requiring moderate inrush current tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GSAP 7-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 7 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

The substitute part 0325007.MXP manufactured by Littelfuse Inc. meets all critical substitution criteria. Both components share identical electrical ratings, response characteristics, and mechanical form factors, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 0325007.MXP from Littelfuse Inc. is the direct functional equivalent for the obsolete GSAP 7-R. Selection of this substitute is supported by:

• Identical electrical specifications (7A, 250VAC, Slow Blow response)
• Matching mechanical form factor (3AB, 3AG, 1/4" x 1-1/4" Axial)
• Active product status ensuring ongoing availability and supply chain continuity
• Equivalent regulatory compliance (CE, CSA, PSE certifications present on both components; 0325007.MXP includes additional K-MARK and UL approvals)
• ROHS3 compliance and REACH unaffected status on both parts

The dimensional variance (0.003" diameter and 0.008" length difference) falls within standard manufacturing tolerances for this component category and does not affect functional compatibility in Through Hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 0325007.MXP directly replace the GSAP 7-R in existing circuit designs?

A: Yes. Both components share identical current rating (7A), voltage rating (250VAC), response time (Slow Blow), and mechanical package (3AB, 3AG, 1/4" x 1-1/4" Axial). Through Hole mounting compatibility is maintained.

Q: What is the significance of the Obsolete product status for the GSAP 7-R?

A: Obsolete status indicates the GSAP 7-R is no longer manufactured or supported by Bel Fuse Inc. The 0325007.MXP maintains Active status, ensuring continued availability, technical support, and supply chain reliability.

Q: Are there dimensional differences between these components?

A: Minor dimensional variations exist (0.003" diameter and 0.008" length difference). These differences are within standard manufacturing tolerances and do not affect functional performance or mechanical fit in standard Through Hole fuse holders.

Q: Do both components meet the same regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected. The GSAP 7-R carries CE, CSA, cULus, and PSE approvals. The 0325007.MXP carries CE, CSA, K-MARK, PSE, and UL approvals, providing equivalent or enhanced regulatory coverage.

Q: What is the difference in Breaking Capacity between these parts?

A: The GSAP 7-R has a Breaking Capacity of 200A at rated voltage, while the 0325007.MXP has 400A. Both values exceed standard circuit protection requirements for 7A applications and do not affect substitution compatibility.
