Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S506-80-R are qualified based on strict electrical and mechanical parameter matching:

Primary Matching Criteria:

• Current Rating: 80 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed meet these criteria. Variations in secondary parameters such as Melting I²t, DC Cold Resistance, Operating Temperature range, and Approval Agency certifications are noted but do not disqualify substitution eligibility when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Eaton - Electronics Division Variants (BK/S506-80-R, BK1/S506-80-R): These parts are direct manufacturer variants of the S506-80-R. All three share identical electrical and mechanical specifications. Selection among these three Eaton parts may be based on inventory availability and internal part designation requirements. Approval agencies include BSI, CCC, CSA, IMQ, SEMKO, UR, and VDE.

SCHURTER Inc. Parts (0034.3106, 0034.3761, 0034.5606.11): These SCHURTER parts meet all primary electrical and mechanical parameters. Operating temperature ranges vary: 0034.3106 and 0034.5606.11 operate from -55°C to 125°C, while 0034.3761 operates from -40°C to 85°C. Approval agencies differ: 0034.3106 holds CCC, cURus, and VDE certifications; 0034.3761 holds cULus certification; 0034.5606.11 holds cURus and VDE certifications. Selection depends on required operating temperature range and applicable regional certifications.

Littelfuse Inc. Part (0218.080HXP): This Littelfuse part meets all primary electrical and mechanical parameters and operates from -55°C to 125°C. Approval agencies include CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE, providing broad regional compliance coverage.

Frequently Asked Questions (FAQ)

Q: Can BK/S506-80-R be used as a direct replacement for S506-80-R?

A: Yes. BK/S506-80-R is a direct manufacturer variant from Eaton - Electronics Division with identical electrical specifications (80 mA, 250 V AC, slow-blow response), mechanical form factor (5mm x 20mm), and breaking capacity (35A). Both require a compatible holder for installation.

Q: What is the difference between the Eaton S506 series variants?

A: S506-80-R, BK/S506-80-R, and BK1/S506-80-R are all Eaton products with identical electrical and mechanical parameters. Differences are internal part designation variants. Selection may be based on inventory availability or internal procurement specifications.

Q: Can SCHURTER parts substitute for Eaton parts?

A: Yes, when electrical and mechanical parameters match. SCHURTER parts 0034.3106, 0034.3761, and 0034.5606.11 all meet the 80 mA, 250 V, 5mm x 20mm, slow-blow specifications. Operating temperature ranges and approval certifications differ and should be verified against application requirements.

Q: What is the difference between SCHURTER 0034.3106 and 0034.3761?

A: Both parts share identical electrical and mechanical specifications (80 mA, 250 V, 5mm x 20mm, slow-blow). Operating temperature ranges differ: 0034.3106 operates from -55°C to 125°C with CCC, cURus, and VDE certifications; 0034.3761 operates from -40°C to 85°C with cULus certification. Selection depends on required temperature range and regional compliance needs.

Q: Can Littelfuse 0218.080HXP replace an Eaton S506-80-R?

A: Yes. The Littelfuse 0218.080HXP meets all primary electrical and mechanical parameters: 80 mA current rating, 250 V AC voltage rating, slow-blow response, 5mm x 20mm form factor, and 35A breaking capacity. It operates from -55°C to 125°C and holds CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE certifications.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the S506-80-R.

Q: What holder types are compatible with these fuses?

A: All listed parts are 5mm x 20mm cartridge fuses requiring a compatible holder. Holder selection must be based on the specific application and equipment design. Consult equipment documentation for holder specifications.

Q: How do Melting I²t values affect substitution?

A: Melting I²t values vary among substitute parts (ranging from 0.0258 to 0.057) but do not disqualify substitution when all primary electrical and mechanical parameters match. Melting I²t represents thermal energy absorption characteristics and is a secondary parameter for this substitution analysis.
