Key Parameters

Substitute Part Grouping Explanation

Substitution for the GSC2-1/2 is based on the following electrical and mechanical parameters derived from the substitute parts data:

• Current Rating: 2.5 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package/Case: 5mm x 20mm
• Mounting Type: Requires Holder
• Breaking Capacity @ Rated Voltage: 100A
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant

The substitute parts 023902.5HXP and 023902.5MXP, both manufactured by Littelfuse, meet these electrical and mechanical specifications and are therefore qualified as equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both Littelfuse substitute parts 023902.5HXP and 023902.5MXP are Active products with ROHS3 compliance, matching the regulatory status of the GSC2-1/2. Both substitutes carry identical electrical ratings (2.5 A, 250 V AC), response characteristics (Slow Blow), and mechanical specifications (5mm x 20mm cartridge format requiring holder). Both parts hold equivalent approval certifications including CE, CSA, KC, PSE, and UL. Selection between the two Littelfuse alternatives may be based on packaging preference (023902.5HXP supplied in Bulk with 2200 pieces available; 023902.5MXP supplied in Bulk with 3140 pieces available) and internal part numbering conventions within the Littelfuse 239 series.

Frequently Asked Questions (FAQ)

Q: What makes 023902.5HXP and 023902.5MXP suitable substitutes for GSC2-1/2?

A: Both Littelfuse parts match the critical electrical parameters: 2.5 A current rating, 250 V AC voltage rating, and slow blow response time. Both are glass cartridge fuses in 5mm x 20mm format requiring a holder, with identical breaking capacity (100A) and operating temperature range (-55°C ~ 125°C). Both maintain ROHS3 compliance and Active product status.

Q: Are there differences between 023902.5HXP and 023902.5MXP?

A: Both parts are electrically and mechanically identical. The primary differences are packaging format (both Bulk) and current inventory levels (023902.5HXP: 2200 pieces; 023902.5MXP: 3140 pieces). Both belong to the Littelfuse 239 series.

Q: What is the significance of the 5mm x 20mm package specification?

A: This dimension specifies the physical cartridge size and indicates that both substitute parts require a compatible fuse holder for installation. The GSC2-1/2 specifications do not explicitly state package dimensions in the provided input, but the substitute parts' 5mm x 20mm format represents the standard cartridge specification for this current and voltage class.

Q: Do the substitute parts carry the same certifications as the original?

A: Yes. Both 023902.5HXP and 023902.5MXP carry CE, CSA, KC, PSE, and UL approvals, providing equivalent regulatory coverage for applications requiring these certifications.

Q: What is the DC Cold Resistance specification?

A: Both Littelfuse substitutes specify 0.0583 Ohms DC cold resistance and 79.705 melting I²t, providing consistent electrical performance characteristics for circuit protection applications.
