GGM1/2 Equivalent & Substitute Parts Reference

Part Overview

The GGM1/2 is a 5X20MM fuse rated at 250V with 1/2A (500mA) current capacity, manufactured by Mersen USA Newburyport-MA L.L.C. This cartridge fuse is designed for circuit protection in applications requiring fast-blow response characteristics. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical ratings and mechanical dimensions are required due to inventory constraints, application redesigns, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GGM1/2 is determined by the following critical parameters:

• Voltage Rating: 250V AC/DC
• Current Rating: 500mA (1/2A)
• Package Dimensions: 5mm x 20mm
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• RoHS Compliance: ROHS3 Compliant

The substitute part 0235.500MXP manufactured by Littelfuse meets all mandatory electrical and mechanical criteria for direct substitution. Both parts share identical voltage and current ratings, package dimensions, and fuse construction type. Compliance certifications and operating temperature ranges support interchangeability in equivalent circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The 0235.500MXP from Littelfuse is a qualified substitute for the GGM1/2. Both parts are Active status products with ROHS3 compliance. The Littelfuse part carries multiple international approvals (CE, CSA, KC, UL) and operates across the industrial temperature range of -55°C to 125°C. Electrical parameters—voltage rating, current rating, and response characteristics—are identical. Physical dimensions and fuse construction are equivalent. Selection between these parts should be based on availability, packaging format (Box versus Bulk), and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 0235.500MXP directly replace the GGM1/2 in existing designs?

A: Yes. Both parts share identical electrical ratings (250V, 500mA), package dimensions (5mm x 20mm), and fuse type (Cartridge, Glass). No circuit modifications are required.

Q: What are the key parameters that determine substitution eligibility?

A: Voltage rating, current rating, package dimensions, fuse type, and response time must match exactly. The GGM1/2 and 0235.500MXP meet all these criteria.

Q: Does packaging format affect substitution?

A: Packaging format (Box versus Bulk) affects inventory handling and procurement but does not impact electrical or mechanical compatibility. Both formats contain identical fuse cartridges.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and Active status. The Littelfuse part includes documented approvals from CE, CSA, KC, and UL. Compliance certifications do not prevent substitution.

Q: What is the operating temperature range for these fuses?

A: The Littelfuse 0235.500MXP operates from -55°C to 125°C. The GGM1/2 operating temperature is not specified in available documentation.
