GSA1 Equivalent & Substitute Parts Reference

Part Overview

The GSA1 is a midget time-delay ceramic fuse manufactured by Mersen USA Newburyport-MA L.L.C. This component is classified as an active product with ROHS3 compliance. The GSA1 serves as a protective device in electrical circuits requiring time-delay response characteristics. Equivalent substitute parts are necessary when GSA1 inventory is unavailable or when sourcing from alternative manufacturers is required for supply chain optimization or cost considerations.

Substitute Part Grouping Explanation

Substitute parts for the GSA1 are identified from the Littelfuse Inc. 326 series ceramic fuse cartridge line. The substitution logic is based on the following electrical and mechanical parameters provided in the input data:

• Fuse Type: Cartridge, Ceramic (matches GSA1 ceramic construction)
• Current Rating: 1 A (electrical compatibility)
• Voltage Rating - AC: 250 V (circuit protection level)
• Voltage Rating - DC: 125 V (dual-voltage capability)
• Response Time: Slow Blow (time-delay characteristic matching GSA1)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (mechanical compatibility)
• RoHS Status: ROHS3 Compliant (regulatory alignment)
• Product Status: Active (ongoing availability)

All three substitute parts (0326001.HXP, 0326001.MXP, 0326001.VXP) meet these criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse 326 series substitute parts (0326001.HXP, 0326001.MXP, 0326001.VXP) are active products with ROHS3 compliance, matching the regulatory status of the GSA1. Each substitute carries CE, CSA, PSE, and UL approvals, confirming compliance with international safety standards. Selection among the three substitutes may be based on inventory availability: 0326001.MXP offers the highest stock level at 1150 pieces, while 0326001.HXP and 0326001.VXP provide alternative sourcing with 1010 and 919 pieces respectively.

Frequently Asked Questions (FAQ)

Q: What makes these Littelfuse parts direct substitutes for the GSA1?

A: The substitute parts share identical electrical ratings (1 A, 250 V AC, 125 V DC), matching response time (slow blow/time delay), ceramic construction, and mechanical package specifications (3AB, 3AG, 1/4" x 1-1/4"). All are ROHS3 compliant and active products.

Q: Are there differences between 0326001.HXP, 0326001.MXP, and 0326001.VXP?

A: All three parts are electrically and mechanically identical. Differences exist only in packaging format (all listed as Bulk) and inventory quantities. Selection should be based on supply availability and procurement requirements.

Q: What is the mounting requirement for these substitute fuses?

A: All substitute parts require a holder. The package designation 3AB, 3AG indicates compatibility with standard 1/4" x 1-1/4" fuse holders.

Q: Do the substitute parts maintain the same breaking capacity as the GSA1?

A: The substitute parts specify a breaking capacity of 100A AC and 10kA DC at rated voltage. GSA1 breaking capacity specifications are not provided in the input data.

Q: Are there any temperature operating range considerations?

A: The substitute parts operate across -55°C to 125°C. GSA1 operating temperature range is not specified in the input data.
