Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.7100.49 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating - AC: 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)

Substitute parts are grouped into two categories: direct form-fit-function equivalents and parametric equivalents with expanded voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 7010.7100.47 is the primary direct substitute for the obsolete 7010.7100.49. Both components share identical electrical and mechanical specifications, including current rating, voltage rating, response time, package dimensions, and breaking capacity. The 7010.7100.47 is active in production status and carries ROHS3 compliance certification, making it suitable for new designs and ongoing procurement.

SCHURTER 7010.7100.13 is a parametric equivalent offering expanded voltage capability with dual AC/DC rating at 125 V. This part maintains all critical electrical parameters including current rating, response time, and breaking capacity. The 7010.7100.13 is active in production and ROHS3 compliant. The addition of 125 V DC rating provides enhanced application flexibility without compromising AC performance.

SCHURTER 7010.6390.13 is a parametric equivalent from the 172321 series with identical current, voltage, and mechanical specifications to the 7010.7100.13. This part differs in melting I²t value (1.6 versus 1.4) and series designation. The 7010.6390.13 is active in production and ROHS3 compliant. Selection between 7010.7100.13 and 7010.6390.13 depends on specific thermal response requirements defined by circuit protection design parameters.

All substitute parts carry CSA and UR approval certifications or equivalent regulatory compliance, supporting use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.7100.47 directly replace the obsolete 7010.7100.49?

A: Yes. The 7010.7100.47 is a direct form-fit-function equivalent with identical electrical ratings (2.5 A, 125 V AC), response time (Fast Blow), package dimensions (0.093" Dia x 0.315" L), and breaking capacity (300 A). Both components are mounted through-hole with non-standard axial cartridge packaging.

Q: What is the difference between 7010.7100.13 and 7010.6390.13?

A: Both parts are parametric equivalents with identical current ratings (2.5 A), AC voltage ratings (125 V), DC voltage ratings (125 V), response time (Fast Blow), and package dimensions. The primary difference is the melting I²t value: 7010.7100.13 has 1.4 while 7010.6390.13 has 1.6. Additionally, they belong to different series designations (172322 versus 172321).

Q: Are the substitute parts RoHS compliant?

A: Yes. All active substitute parts (7010.7100.47, 7010.7100.13, and 7010.6390.13) are ROHS3 compliant. The obsolete 7010.7100.49 does not specify RoHS status.

Q: Can I use a substitute part with DC voltage rating in an AC-only application?

A: Yes. Parts with dual AC/DC voltage ratings (7010.7100.13 and 7010.6390.13) are suitable for AC-only applications. The 125 V AC rating remains valid and unchanged. The additional DC rating does not affect AC performance.

Q: What is the significance of the melting I²t parameter difference?

A: The melting I²t value (1.4 for 7010.7100.49 and 7010.7100.47 versus 1.6 for 7010.6390.13) represents the thermal energy required to melt the fuse element. This parameter affects the fuse's response to overcurrent conditions. Selection between parts with different I²t values depends on circuit protection design requirements and thermal response specifications.

Q: Are all substitute parts available in the same packaging format?

A: The 7010.7100.47, 7010.7100.13, and 7010.6390.13 all use identical package dimensions (0.093" Dia x 0.315" L, 2.36mm x 8.00mm) and cartridge non-standard axial form factor. The 7010.6390.13 is supplied in bulk packaging, while 7010.7100.47 and 7010.7100.13 packaging specifications are not detailed in the provided data.

Q: Which regulatory certifications apply to the substitute parts?

A: The 7010.7100.47 carries CSA, GAM T1, and UR approvals. The 7010.7100.13 carries CSA and UR approvals. The 7010.6390.13 does not specify approval agencies. All parts are classified under ECCN EAR99 and HTSUS 8536.10.0040.
