Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.6440.39 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Current Rating: 7 A (exact match required)
• Voltage Rating AC: 125 V (exact match required)
• Voltage Rating DC: 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)

Mechanical Parameters:

• 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)

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 85°C (exact match required)

All identified substitute parts meet these criteria and are available in active product status.

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.6440.47

The 7010.6440.47 is the recommended direct replacement for the obsolete 7010.6440.39. Both parts are from the same 172321 series and share identical electrical and mechanical specifications. The 7010.6440.47 holds active product status and is ROHS3 compliant with REACH unaffected certification, supporting modern regulatory requirements. Inventory availability is 1072 units.

Secondary Substitute: SCHURTER 7010.7140.13

The 7010.7140.13 provides parametric equivalence across all critical electrical and mechanical parameters. This part is from the 172322 series and holds active product status with CSA and UR approval agency certifications. The melting I²t value differs at 13 compared to the main part's 15, representing a minor thermal characteristic variation. This part is ROHS3 compliant with REACH unaffected status. Inventory availability is 637 units in bulk packaging.

Tertiary Substitute: SCHURTER 7010.6440.13

The 7010.6440.13 maintains full parametric equivalence within the 172321 series. Product status and compliance information are not specified in available data. Inventory availability is 805 units.

All three substitute parts maintain identical current rating, voltage ratings, response time, mounting configuration, package dimensions, and operating temperature range as the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.6440.47 be used as a direct replacement for the 7010.6440.39?

A: Yes. The 7010.6440.47 is electrically and mechanically identical to the 7010.6440.39 across all specified parameters: 7 A current rating, 125 V AC/DC voltage rating, fast-blow response, through-hole mounting, and identical physical dimensions of 0.093" Dia x 0.315" L. The primary difference is active product status and modern compliance certifications (ROHS3, REACH).

Q: What is the difference between the 7010.6440.47 and 7010.7140.13?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The 7010.7140.13 differs in series designation (172322 versus 172321), approval agency certifications (CSA, UR versus GAM T1), and melting I²t value (13 versus 15). The melting I²t parameter affects thermal response characteristics but does not alter the 7 A current rating or 125 V voltage rating.

Q: Are there packaging differences between substitute parts?

A: The 7010.7140.13 is specified with bulk packaging, while 7010.6440.47 and 7010.6440.13 do not specify packaging type. All three parts use identical cartridge, non-standard (axial) package cases with matching physical dimensions.

Q: What compliance certifications apply to each substitute part?

A: The 7010.6440.47 carries GAM T1 approval with ROHS3 compliance and REACH unaffected status. The 7010.7140.13 carries CSA and UR approvals with ROHS3 compliance and REACH unaffected status. The 7010.6440.13 compliance information is not specified.

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

A: Yes. All parts are rated for 125 V AC and 125 V DC operation, supporting dual-voltage applications within the specified voltage range.

Q: What is the breaking capacity specification?

A: All substitute parts maintain a breaking capacity of 300 A at rated voltage, matching the original 7010.6440.39 specification.
