SCHURTER 8020.5083.G Equivalent & Substitute Parts

Part Overview

The SCHURTER 8020.5083.G is a 32 A ceramic cartridge fuse rated for 440 V AC and 63 V DC operation. This fast-blow fuse is designed for applications requiring the 3AB, 3AG, 1/4" x 1-1/4" holder format and is currently in active production status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 8020.5083.G is determined by the following critical parameters:

Mechanical Compatibility: Package format (3AB, 3AG, 1/4" x 1-1/4"), physical dimensions, and holder mounting requirements must be identical or functionally equivalent to ensure installation without modification.

Electrical Compatibility: Current rating, voltage ratings (both AC and DC), response time classification (fast blow), and breaking capacity must meet or exceed the original specification to maintain circuit protection integrity.

Functional Requirements: Fuse type (ceramic cartridge), mounting type (requires holder), and thermal operating range must support the intended application environment.

The identified substitute part BK-ADC-30-R from Eaton - Electronics Division meets the mechanical compatibility criteria through identical package format and dimensions. However, electrical parameter variations exist that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 8020.5083.G and Eaton BK-ADC-30-R are active production components with ROHS3 compliance and established regulatory approvals. The SCHURTER part carries broader certification coverage (CE, CSA, cURus, UKCA, UL) compared to the Eaton substitute (cURus, UL).

The Eaton BK-ADC-30-R provides higher voltage ratings (500 V AC/DC versus 440 V AC/63 V DC) and superior breaking capacity (30 kA AC versus 1.5 kA AC), which may exceed application requirements. The current rating difference (30 A versus 32 A) represents a 6.25% reduction and must be evaluated against circuit load specifications.

Physical dimensions show minimal variance (0.252" versus 0.250" diameter), which remains within standard holder tolerances for the 3AB, 3AG format. Operating temperature range expansion (-50°C to 125°C versus -40°C to 85°C) provides broader environmental compatibility.

Selection between these components should be based on specific application voltage requirements, current load specifications, and regulatory certification mandates for the target market.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK-ADC-30-R directly replace the SCHURTER 8020.5083.G in all applications?

A: Direct replacement requires verification of three factors: (1) circuit voltage does not exceed 440 V AC or 63 V DC, (2) circuit current does not exceed 30 A, and (3) regulatory certifications required by the application include cURus or UL approval. The SCHURTER part's broader certification portfolio (CE, UKCA) may be mandatory for specific markets.

Q: What is the significance of the current rating difference between 32 A and 30 A?

A: The 2 A difference represents a 6.25% reduction in current capacity. This substitute is suitable only for circuits designed for 30 A operation or lower. Circuits requiring the full 32 A capacity must use the original SCHURTER part.

Q: Are the physical dimensions compatible with existing 3AB, 3AG holders?

A: Both parts conform to the 3AB, 3AG, 1/4" x 1-1/4" standard format. The diameter variance (0.250" to 0.252") falls within standard holder tolerance specifications and does not require mechanical modification.

Q: How do voltage ratings affect substitution eligibility?

A: The Eaton part's higher voltage ratings (500 V AC/DC) are compatible with applications operating at or below the SCHURTER part's ratings (440 V AC/63 V DC). However, if the application specifically requires operation above 440 V AC or 63 V DC, only the Eaton part is suitable.

Q: What is the impact of the operating temperature range difference?

A: The Eaton part operates across a wider temperature range (-50°C to 125°C versus -40°C to 85°C). For applications within the SCHURTER range, both parts are equivalent. For extreme temperature environments, the Eaton part provides extended capability.

Q: Which certifications are critical for my application?

A: Certification requirements depend on target market and application class. The SCHURTER part includes CE and UKCA markings required for European markets. The Eaton part includes cURus and UL approvals. Verify your specific regulatory requirements before substitution.
