Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 2040.0812 is determined by the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Mounting Type: Through Hole
• Package / Case: Radial, Can, Vertical
• Response Time: Slow Blow
• Physical Dimensions: 0.335" Dia x 0.335" H (8.50mm x 8.50mm)

Two active substitute parts meet these core electrical and mechanical parameters: SCHURTER 0034.6812 and SCHURTER 0034.7312. Both maintain identical current ratings, AC voltage ratings, mounting configurations, and physical dimensions as the obsolete 2040.0812.

Parameter Comparison

Engineering Selection Recommendations

Both SCHURTER 0034.6812 and SCHURTER 0034.7312 are active products suitable for replacing the obsolete 2040.0812 in applications requiring 500 mA, 250 V AC board mount fuses with slow-blow response.

SCHURTER 0034.6812 provides extended operating temperature range (-55°C to 125°C) and dual voltage rating capability (250 V AC / 125 V DC), with approval certifications including CCC, cURus, KC, and VDE. This part maintains identical melting I²t characteristics (2.5) to the original 2040.0812.

SCHURTER 0034.7312 operates within the same temperature range as the original part (-40°C to 85°C) and features increased breaking capacity (50A) with cULus certification. This part has a lower melting I²t value (0.898) compared to the original specification.

Both substitute parts are available in active production status with ROHS3 compliance and REACH unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.6812 be used as a direct replacement for 2040.0812?

A: Yes. Both parts share identical current rating (500 mA), AC voltage rating (250 V), fuse type, mounting configuration, package style, response time, and physical dimensions. The 0034.6812 is an active product with extended temperature range and dual voltage capability.

Q: What is the difference between 0034.6812 and 0034.7312?

A: The primary differences are melting I²t (2.5 vs. 0.898), breaking capacity (35A AC / 50A DC vs. 50A), operating temperature range (-55°C to 125°C vs. -40°C to 85°C), and approval certifications (CCC, cURus, KC, VDE vs. cULus). Both maintain the same current and voltage ratings.

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

A: The 2040.0812 was supplied in standard packaging. Both substitute parts (0034.6812 and 0034.7312) are available in Cut Tape (CT) packaging format.

Q: Do the substitute parts meet the same compliance standards?

A: All parts are ROHS3 compliant and REACH unaffected. Approval certifications differ: the original 2040.0812 carries CCC, cURus, and VDE approvals; 0034.6812 adds KC certification; 0034.7312 carries cULus certification.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring extended temperature operation and DC voltage capability, 0034.6812 is appropriate. For applications matching the original operating temperature range, 0034.7312 offers higher breaking capacity.
