SCHURTER 7022.0650 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7022.0650 is a 3.15 A ceramic cartridge fuse rated for 500 V AC operation. This component is designed for applications requiring fast-blow response characteristics and is housed in a 3AB/3AG form factor (1/4" x 1-1/4"). The part is currently active in production with 931 units in stock. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters across all candidates:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating (AC): 500 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute parts SCHURTER 8020.5073 and SCHURTER 8020.5073.G meet all mandatory electrical and mechanical parameters. Differences in Breaking Capacity, Melting I²t, and DC voltage rating do not disqualify substitution when AC operation at 500 V and 3.15 A is the primary application requirement.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and regulatory approval. The 7022.0650 carries UR approval, while both substitute parts carry cURus approval. Selection between these parts should be based on:

1. Regulatory approval requirements for the target application (UR vs. cURus)
2. Breaking capacity requirements: The 7022.0650 provides 150kA breaking capacity, while 8020.5073 and 8020.5073.G provide 1.5kA
3. DC voltage operation: The 8020.5073.G is rated for 400 V DC in addition to 500 V AC, providing expanded application flexibility
4. Inventory availability and lead time considerations

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 8020.5073 directly replace SCHURTER 7022.0650?

A: Yes, for AC applications at 500 V and 3.15 A. Both parts share identical current rating, voltage rating, fuse type, response time, package dimensions, and operating temperature range. Differences in breaking capacity and approval agency must be evaluated against application requirements.

Q: What is the difference between 8020.5073 and 8020.5073.G?

A: The 8020.5073.G includes a 400 V DC voltage rating in addition to the 500 V AC rating. The 8020.5073 does not specify a DC rating. Both parts are otherwise electrically and mechanically identical.

Q: Are these parts physically interchangeable?

A: Yes. All three parts use the 3AB/3AG form factor with identical dimensions of 0.250" diameter x 1.252" length (6.35mm x 31.80mm) and require the same holder type.

Q: Why do the substitute parts have lower breaking capacity?

A: Breaking capacity is a specified parameter that differs between part numbers. Application circuits must be evaluated to determine if 1.5kA breaking capacity is sufficient, or if the 150kA rating of the 7022.0650 is required.

Q: Which approval agency certification should I use?

A: Selection depends on application requirements. The 7022.0650 carries UR approval; the substitute parts carry cURus approval. Verify which certification is required by your application standards or regional regulations.
