GSC2 Electronic Time Delay Fuse Equivalent & Substitute Parts

Part Overview

The GSC2 is an electronic time delay fuse manufactured by Mersen USA Newburyport-MA L.L.C. This component is classified as a time delay electronic fuse in glass construction, designed for circuit protection applications requiring controlled response characteristics. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the GSC2 may be unavailable or when inventory optimization is required.

Substitute Part Grouping Explanation

Substitute parts for the GSC2 are identified from the Littelfuse Inc. 239 series glass fuse cartridges. The substitution logic is based on the following alignment criteria:

Key Parameters for Substitution:

Fuse Type: Cartridge, Glass
Current Rating: 2 A
Voltage Rating (AC): 250 V
Response Time: Slow Blow
Package / Case: 5mm x 20mm
Mounting Type: Requires Holder
Product Status: Active
RoHS Compliance: ROHS3 Compliant

All identified substitute parts (0239002.HXP, 0239002.MXP, 0239002.TXP, 0239002.VXP) share identical electrical and mechanical specifications with the GSC2, differing only in manufacturer designation and packaging format (Bulk vs. Box). These parts are direct functional equivalents suitable for replacement applications.

Engineering Selection Recommendations

All four Littelfuse 239 series substitute parts (0239002.HXP, 0239002.MXP, 0239002.TXP, 0239002.VXP) are functionally equivalent to the GSC2 and maintain identical electrical performance characteristics. Selection among these alternatives is determined by availability and packaging requirements:

0239002.HXP: 2400 Pcs inventory available, Bulk packaging
0239002.MXP: 1610 Pcs inventory available, Bulk packaging
0239002.TXP: 719 Pcs inventory available, Bulk packaging
0239002.VXP: 931 Pcs inventory available, Bulk packaging

All substitute parts carry Active product status, ROHS3 compliance, and identical regulatory approvals (CE, CSA, KC, PSE, UL). The choice between substitutes depends on procurement volume requirements and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0239002 series parts directly replace the GSC2?

A: Yes. The 0239002.HXP, 0239002.MXP, 0239002.TXP, and 0239002.VXP parts share identical electrical specifications (2 A, 250 V AC, Slow Blow response) and mechanical dimensions (5mm x 20mm). All require the same holder type and operate within the same temperature range (-55°C to 125°C).

Q: What is the difference between the four Littelfuse substitute options?

A: The four parts are electrically and mechanically identical. Differences exist only in manufacturer part number designation and current inventory levels. Selection should be based on procurement availability and packaging format (all are supplied in Bulk).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (0239002.HXP, 0239002.MXP, 0239002.TXP, 0239002.VXP) are ROHS3 compliant, matching the GSC2 compliance status.

Q: Do the substitute parts require the same holder as the GSC2?

A: Yes. All substitute parts are 5mm x 20mm glass cartridge fuses that require a holder for installation. The mechanical dimensions and mounting requirements are identical to the GSC2.

Q: What regulatory approvals do the substitute parts carry?

A: All substitute parts carry CE, CSA, KC, PSE, and UL approvals, identical to the GSC2 certification profile.
