• 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)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)
• Melting I²t: 0.0094 (exact match required)
• Operating Temperature Range: -55°C to 85°C (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)

Two substitute parts meet these criteria and are identified below.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 7010.7030.47 is the direct substitute for the obsolete 7010.7030.49. Both parts are identical across all electrical and mechanical parameters, including current rating, voltage rating, response time, package dimensions, and breaking capacity. The 7010.7030.47 carries active product status and meets ROHS3 compliance and REACH unaffected requirements, making it suitable for new designs and production applications requiring the same performance characteristics as the original part.

SCHURTER 7010.7030.13 is a parametric equivalent that provides additional functionality through dual voltage rating capability (125 V AC and 125 V DC). This part maintains all critical electrical and mechanical parameters identical to the main part and is available in bulk packaging. The 7010.7030.13 carries active product status and meets ROHS3 compliance and REACH unaffected requirements. The addition of DC voltage rating capability does not compromise AC-only applications and provides expanded operational flexibility for designs requiring DC circuit protection.

Both substitute parts belong to the SCHURTER 172322 series and maintain compatibility with the original approval agencies (CSA and UR). The 7010.7030.47 retains GAM T1 approval present in the original part.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7030.47 be used as a direct replacement for the 7010.7030.49?

A: Yes. The 7010.7030.47 is electrically and mechanically identical to the 7010.7030.49 across all specified parameters, including current rating, voltage rating, response time, package dimensions, and breaking capacity. The primary difference is product status: the 7010.7030.47 is active while the 7010.7030.49 is obsolete.

Q: What is the difference between the 7010.7030.47 and 7010.7030.13?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications for AC operation at 250 mA and 125 V. The 7010.7030.13 includes an additional DC voltage rating of 125 V, enabling use in DC circuits. The 7010.7030.13 is available in bulk packaging, while the 7010.7030.47 packaging is not specified.

Q: Are the substitute parts physically compatible with the original PCB design?

A: Yes. Both substitute parts maintain the identical package configuration (Cartridge, Non-Standard Axial) and dimensions (0.093" Dia x 0.315" L / 2.36mm x 8.00mm), ensuring mechanical compatibility with through-hole mounting on existing circuit boards designed for the 7010.7030.49.

Q: Do the substitute parts meet the same regulatory approvals as the original part?

A: The 7010.7030.47 meets CSA, GAM T1, and UR approvals, matching the original part. The 7010.7030.13 meets CSA and UR approvals. Both substitute parts are ROHS3 compliant and REACH unaffected.

Q: What is the melting I²t value, and is it the same across all three parts?

A: The melting I²t value is 0.0094 for all three parts (7010.7030.49, 7010.7030.47, and 7010.7030.13). This parameter defines the thermal energy required to melt the fuse element and is identical across all variants.

Q: Can the 7010.7030.13 be used in AC-only applications?

A: Yes. The 7010.7030.13 is rated for 125 V AC operation and maintains all AC performance characteristics identical to the original part. The additional DC voltage rating does not affect AC circuit operation.

Q: What is the breaking capacity, and is it consistent across substitute parts?

A: The breaking capacity is 300 A at rated voltage for all three parts. This specification defines the maximum fault current the fuse can safely interrupt without damage or hazard.
