Substitute Part Grouping Explanation

Substitute parts for the 3-103-092 are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitutes (Series MGA): Parts 3410.0022.02, 3410.0022.03, and 3410.0022.04 share identical electrical ratings (250 mA, 125 V AC/DC), response time (Fast Blow), package configuration (2-SMD, Square End Block), and physical dimensions (3.20mm x 1.55mm x 1.55mm). These parts differ in operating temperature range (-55°C ~ 150°C versus -55°C ~ 125°C) and melting I²t value (0.0009 versus 0.00013), representing design improvements within the MGA series. Packaging format differs: 3410.0022.x variants are supplied in Tape & Reel format.

Parametric Equivalent (Series MGA-A): Part 3-103-091 maintains identical electrical specifications, response time, package type, and dimensions as the main part 3-103-092. Both are MGA-A series components with matching melting I²t (0.00013) and operating temperature range (-55°C ~ 125°C). The primary difference is packaging format: 3-103-091 is supplied in Cut Tape format while 3-103-092 is supplied in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. The 3-103-091 parametric equivalent is the direct functional replacement, sharing identical electrical characteristics, melting I²t value, and approval certifications (cURus, UL) with the main part. Selection between 3-103-091 and 3-103-092 depends solely on packaging requirements: Cut Tape format versus Tape & Reel format.

The 3410.0022.x series (parts 02, 03, 04) represent upgraded alternatives within the MGA series. These parts maintain all critical electrical parameters and mechanical compatibility but feature extended operating temperature range (-55°C ~ 150°C) and higher melting I²t values (0.0009). These upgrades are suitable for applications requiring enhanced thermal performance. Approval agency certification differs: MGA series parts carry cURus certification only, while MGA-A series parts carry both cURus and UL certifications.

Frequently Asked Questions (FAQ)

Q: Can 3410.0022.04 directly replace 3-103-092 on an existing PCB assembly?

A: Yes. Both parts share identical electrical ratings (250 mA, 125 V AC/DC), response time (Fast Blow), package configuration (2-SMD, Square End Block), and physical dimensions (3.20mm x 1.55mm x 1.55mm). PCB footprints are mechanically compatible. Functional substitution is valid for applications within the -55°C ~ 125°C operating range of the original part.

Q: What is the difference between 3-103-091 and 3-103-092?

A: Both parts are electrically and mechanically identical MGA-A series fuses with matching current ratings, voltage ratings, response time, package type, and dimensions. The sole difference is packaging format: 3-103-091 is supplied in Cut Tape (CT) format while 3-103-092 is supplied in Tape & Reel (TR) format. Selection depends on assembly line equipment compatibility and procurement requirements.

Q: Why do 3410.0022.x parts have different melting I²t values?

A: The melting I²t value (0.0009 for MGA series versus 0.00013 for MGA-A series) reflects design differences in thermal response characteristics. Both values are within the same current rating class and maintain identical breaking capacity specifications. The difference does not affect substitution compatibility for standard applications.

Q: Are all substitute parts UL certified?

A: No. The main part 3-103-092 and parametric equivalent 3-103-091 carry dual certification (cURus, UL). The upgrade substitutes 3410.0022.02, 3410.0022.03, and 3410.0022.04 carry cURus certification only. Applications requiring UL certification must use 3-103-092 or 3-103-091.

Q: Can I use 3410.0022.x parts in applications with operating temperatures above 125°C?

A: Yes. The 3410.0022.x series supports operating temperatures up to 150°C, compared to 125°C for the MGA-A series. This extended range makes them suitable for higher-temperature environments while maintaining all other electrical and mechanical specifications.
