Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GSC4 are identified based on the following electrical and mechanical parameters:

• Current Rating: 4 A
• Voltage Rating (AC): 125 V
• Fuse Type: Cartridge, Glass
• Package/Case: 5mm x 20mm
• Response Time: Slow Blow
• Mounting Type: Requires Holder

The substitute parts 0239004.HXP and 0239004.MXP, both manufactured by Littelfuse Inc., meet these core electrical and mechanical specifications. Both are classified as active products with ROHS3 compliance and identical approval agency certifications (CE, CSA, KC, PSE, UL).

Parameter Comparison

Engineering Selection Recommendations

Both 0239004.HXP and 0239004.MXP are suitable substitutes for the GSC4 based on the following criteria:

• All three parts maintain active product status, ensuring continued availability and manufacturer support.
• The Littelfuse substitute parts carry identical regulatory approvals (CE, CSA, KC, PSE, UL) and ROHS3 compliance, meeting the same environmental and safety standards as the main part.
• Both substitutes are specified as 4 A, 125 V AC slow-blow cartridge fuses in 5mm x 20mm form factor, matching the functional requirements of the GSC4.
• The 10kA breaking capacity and -55°C to 125°C operating temperature range of the substitute parts provide equivalent performance margins.

Selection between 0239004.HXP and 0239004.MXP may be based on packaging preference (both supplied in bulk) and inventory availability (6788 units and 1008 units respectively).

Frequently Asked Questions (FAQ)

Q: What makes 0239004.HXP and 0239004.MXP equivalent to GSC4?

A: Both Littelfuse parts are specified as 4 A, 125 V AC slow-blow glass cartridge fuses in 5mm x 20mm package format. They share identical electrical ratings, response characteristics, breaking capacity, and regulatory certifications with the GSC4.

Q: Are there any packaging differences between the main part and substitutes?

A: Yes. The GSC4 is supplied in box packaging, while both 0239004.HXP and 0239004.MXP are supplied in bulk packaging. This affects order quantities and handling but does not impact electrical or mechanical compatibility.

Q: Do the substitute parts require the same holder as the GSC4?

A: Both 0239004.HXP and 0239004.MXP require a holder for installation, consistent with the cartridge fuse design. The 5mm x 20mm form factor ensures compatibility with standard fuse holders rated for this package size.

Q: What is the difference between 0239004.HXP and 0239004.MXP?

A: Both parts are identical in electrical specifications, ratings, and certifications. The difference is in inventory availability (6788 units for HXP versus 1008 units for MXP) and potentially in packaging lot or manufacturing date codes.

Q: Are all parts ROHS3 compliant?

A: Yes. The GSC4, 0239004.HXP, and 0239004.MXP all carry ROHS3 compliance certification, meeting current environmental regulations for electronic components.
