Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2040.0710 are qualified based on the following critical parameters:

• Current Rating: 315 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Size / Dimension: 0.335" Dia x 0.335" H (8.50mm x 8.50mm) (exact match required)

Three active substitute parts meet these core electrical and mechanical parameters while offering improved product status and expanded compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0034.6710, 0034.7110, 0034.7210) satisfy the core electrical and mechanical requirements of the 2040.0710. Selection among these alternatives depends on specific application requirements:

0034.6710 provides dual voltage capability with 125 V DC rating and expanded temperature range (-55°C to 125°C), making it suitable for applications requiring DC circuit protection or extended thermal operating conditions. This part carries the broadest compliance certification set including CCC, cURus, KC, and VDE.

0034.7110 and 0034.7210 are functionally equivalent alternatives from the MSTU 250 series with identical electrical characteristics, operating temperature range, and cULus certification. These parts feature increased breaking capacity (50A versus 35A) and reduced melting I²t (0.361 versus 0.8), indicating faster response characteristics. Both parts maintain active product status with confirmed inventory availability.

All substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can 0034.6710 be used in AC-only circuits? A: Yes. The 0034.6710 maintains the 250 V AC rating required for the original application. The additional 125 V DC rating does not restrict AC circuit operation.

Q: What is the significance of the different melting I²t values? A: Melting I²t characterizes the thermal energy required to melt the fuse element. The 0034.6710 with I²t of 0.8 matches the original 2040.0710 characteristic. The 0034.7110 and 0034.7210 with I²t of 0.361 respond faster to overcurrent conditions, providing more sensitive protection.

Q: Are the physical dimensions identical across all substitute parts? A: Yes. All substitute parts maintain the 0.335" diameter by 0.335" height (8.50mm x 8.50mm) radial, can, vertical package configuration, ensuring direct mechanical compatibility.

Q: Which substitute part offers the widest operating temperature range? A: The 0034.6710 operates across -55°C to 125°C, compared to -40°C to 85°C for the original part and both MSTU 250 series alternatives.

Q: Do all substitute parts carry the same compliance certifications as the original? A: No. The 0034.6710 carries CCC, cURus, KC, and VDE certifications. The 0034.7110 and 0034.7210 carry cULus certification only. Application requirements determine which certification set is necessary.
