Littelfuse 030107.5M Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 030107.5M is a 7.5 A glass cartridge fuse rated for 32 V AC/DC operation in 1AG form factor (1/4" x 5/8"). This component is designed for circuit protection in low-voltage applications requiring a cartridge-style fuse that operates within a dedicated holder. The part maintains Active product status and is ROHS3 compliant, making it suitable for current industrial and commercial applications. Substitute parts may be required due to inventory availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution for the Littelfuse 030107.5M is based on strict equivalence across the following critical parameters:

• Current Rating: 7.5 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (exact match required)
• Physical Dimensions: 0.250" Dia x 0.625" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute part 0AGA07.5V meets all these criteria and is therefore a direct parametric equivalent. Both parts are manufactured by Littelfuse Inc., belong to the AGA series, and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 030107.5M and 0AGA07.5V are Active products with identical compliance certifications. Selection between these parts should be based on availability and procurement lead times. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications. The 030107.5M currently maintains higher inventory (916 pcs) compared to 0AGA07.5V (796 pcs), which may influence procurement decisions based on delivery requirements.

Frequently Asked Questions (FAQ)

Q: Can 0AGA07.5V be used as a direct replacement for 030107.5M?

A: Yes. Both parts are parametric equivalents with identical current rating (7.5 A), voltage rating (32 V AC/DC), fuse type (Cartridge, Glass), package designation (1AG), and physical dimensions (0.250" Dia x 0.625" L). They are mechanically and electrically interchangeable.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Both are manufactured by Littelfuse Inc. and belong to the AGA series.

Q: What mounting considerations apply to both parts?

A: Both the 030107.5M and 0AGA07.5V require a dedicated fuse holder for installation. The 1AG form factor (1/4" x 5/8") is a standard cartridge fuse size with established holder compatibility across the industry.

Q: Are there any environmental or temperature-related differences?

A: No operating temperature specifications are provided in the technical data for either part. Both maintain Moisture Sensitivity Level 1 (Unlimited for 030107.5M; Not Applicable for 0AGA07.5V), indicating no moisture-related handling restrictions.

Q: What is the basis for substitution between these parts?

A: Substitution is based on exact equivalence across all provided electrical parameters (current and voltage ratings), mechanical parameters (package type and physical dimensions), and functional classification (cartridge glass fuse type). Both parts are Active products from the same manufacturer and series.
