Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S500-32-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 32 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these mandatory parameters without exception. Variations in secondary parameters such as DC Cold Resistance, Melting I²t, operating temperature range, and approval agency certifications do not disqualify substitution but are documented for engineering reference.

Parameter Comparison

Engineering Selection Recommendations

Eaton S500 Series (BK/S500-32-R, BK1/S500-32-R): These parts are manufactured by Eaton - Electronics Division, the same manufacturer as the primary S500-32-R. Both maintain Active product status and ROHS3 compliance. BK/S500-32-R offers the highest inventory availability at 1190 units. BK1/S500-32-R provides an alternative within the same manufacturer family with 632 units in stock.

Littelfuse 217 Series (0217.032MXP, 0217.032HXP): Both Littelfuse parts are from the 217 series and meet all mandatory electrical and mechanical parameters. These parts carry expanded approval agency certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Operating temperature range is specified as -55°C to 125°C. Both maintain ROHS3 compliance and REACH Unaffected status. 0217.032MXP has 1190 units available; 0217.032HXP has 1127 units available.

SCHURTER FSF 5x20 Series (0034.1527): The SCHURTER part 0034.1527 from the FSF 5x20 series meets all mandatory parameters and carries CCC, cURus, and VDE certifications. This part offers the highest inventory level at 7301 units. Operating temperature range is -55°C to 125°C. ROHS3 compliance and REACH Unaffected status are confirmed.

All substitute parts are suitable for direct replacement in applications requiring a 32 mA, 250 V AC/DC fast-blow glass fuse cartridge in a 5mm x 20mm package.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-32-R be used as a direct replacement for S500-32-R? A: Yes. BK/S500-32-R is a parametric equivalent manufactured by the same company (Eaton - Electronics Division) with identical electrical ratings, fuse type, response time, and package dimensions. Both are ROHS3 compliant and Active products.

Q: What is the difference between 0217.032MXP and 0217.032HXP? A: Both are Littelfuse 217 series parts with identical electrical and mechanical specifications. The difference lies in internal design characteristics reflected in the part number suffix. Both meet all mandatory substitution parameters and carry the same approval certifications.

Q: Why does 0034.1527 have higher inventory than other substitutes? A: Inventory levels reflect current stock availability and do not indicate technical superiority or preference. The SCHURTER 0034.1527 meets all mandatory parameters and is suitable for substitution based on electrical and mechanical equivalence alone.

Q: Are there operating temperature differences between substitutes? A: The primary S500-32-R does not specify an operating temperature range. Littelfuse (0217.032MXP, 0217.032HXP) and SCHURTER (0034.1527) parts specify -55°C to 125°C. This expanded specification does not affect substitution eligibility but provides additional environmental performance data for applications requiring temperature-rated components.

Q: Do all substitutes fit in the same 5mm x 20mm fuse holder? A: Yes. All substitute parts have identical package dimensions of 5mm x 20mm (0.205" Dia x 0.787" L) and require the same holder type. Physical compatibility is guaranteed.

Q: What approval certifications should I consider for my application? A: Selection should be based on application requirements. Littelfuse parts (0217.032MXP, 0217.032HXP) carry the broadest certification set: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. SCHURTER (0034.1527) carries CCC, cURus, and VDE. Eaton parts carry no specified approval agencies. Choose based on your equipment's required certifications.

Q: Is RoHS compliance consistent across all substitutes? A: All parts are RoHS compliant. S500-32-R, BK/S500-32-R, 0217.032MXP, 0034.1527, and 0217.032HXP are ROHS3 compliant. BK1/S500-32-R is RoHS compliant. This difference does not affect substitution eligibility.
