Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.6400.37 is classified as obsolete. For new designs and production applications, selection between active equivalents is determined by product status, compliance certifications, and packaging requirements.

SCHURTER 7010.6400.47 is an active equivalent with full RoHS3 compliance and REACH unaffected status. This part is suitable for applications requiring current regulatory compliance certifications and is available in standard packaging configurations.

SCHURTER 7010.6400.13 is an active equivalent with full RoHS3 compliance and REACH unaffected status. This part is supplied in bulk packaging and serves as the base product number (7010.6400) variant. Selection of this part is appropriate for high-volume production requirements where bulk packaging provides cost efficiency.

Both active substitutes maintain complete electrical and mechanical equivalence to the obsolete 7010.6400.37, ensuring direct functional replacement in existing circuit designs without modification to board layouts or component footprints.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.6400.47 or 7010.6400.13 be used as direct replacements for the 7010.6400.37?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (3 A, 125 V AC/DC), response characteristics (fast blow), breaking capacity (300 A), and physical dimensions (0.093" Dia x 0.315" L). All three parts are members of the 172321 series and are mounted through-hole in the same axial cartridge configuration.

Q: What is the difference between the 7010.6400.47 and 7010.6400.13 substitutes?

A: The primary differences are product status and packaging. The 7010.6400.47 is available in standard packaging, while the 7010.6400.13 is supplied in bulk packaging. Both parts carry identical RoHS3 and REACH compliance certifications and are active products. Selection depends on procurement volume and packaging requirements.

Q: Are there compliance differences between the obsolete 7010.6400.37 and the active substitutes?

A: The active substitutes 7010.6400.47 and 7010.6400.13 are certified as RoHS3 compliant and REACH unaffected. The obsolete 7010.6400.37 does not specify these compliance statuses. For applications subject to RoHS3 or REACH regulations, the active substitutes are required.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All three parts are rated for 125 V AC and 125 V DC operation, permitting use in both alternating and direct current applications within the specified voltage range.

Q: What is the significance of the fast blow response time?

A: Fast blow response indicates the fuse will open rapidly when current exceeds the 3 A rating. This characteristic is suitable for circuits requiring quick protection against overcurrent conditions. All three parts share this response time specification.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts maintain the same axial cartridge dimensions of 0.093" diameter by 0.315" length (2.36mm x 8.00mm), ensuring compatibility with existing through-hole board layouts and component footprints.

Q: What is the melting I²t value and why is it important?

A: The melting I²t of 2.4 represents the thermal energy required to melt the fuse element. This parameter is identical across all three parts and is critical for ensuring consistent overcurrent protection characteristics in circuit design.

Q: Is the 7010.6400.13 suitable for high-volume production?

A: Yes. The 7010.6400.13 is supplied in bulk packaging and is designated as the base product number variant (7010.6400), making it appropriate for high-volume manufacturing where bulk quantities reduce per-unit costs.
