Littelfuse 0218.032H Glass Cartridge Fuse 32 mA 250 VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.032H is a 32 mA, 250 VAC slow-blow glass cartridge fuse in 5mm x 20mm form factor, designed for circuit protection in AC and DC applications. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must preserve the 32 mA current rating, 250 V voltage rating, slow-blow response characteristic, and 5x20mm physical dimensions to ensure direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0218.032H is determined by strict equivalence across the following critical parameters:

• Current Rating: 32 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Characteristic: Slow Blow (exact match required)
• Physical Form Factor: 5mm x 20mm cartridge (exact match required)
• Fuse Type: Glass cartridge requiring holder (exact match required)

Substitute parts are grouped into two categories:

Littelfuse Series 218 Parametric Equivalents: Parts 0218.032HXP, 0218.032MXBP, 0218.032MXP, and 0218.032TXP maintain all critical electrical and mechanical parameters. These parts differ in packaging designation (HXP, MXBP, MXP, TXP variants) and minor variations in DC cold resistance and melting I²t values, but all satisfy the core substitution criteria. All are active products with RoHS3 compliance.

Eaton Series GDC and S506 Cross-Manufacturer Equivalents: Parts BK/GDC-32MA, BK/S506-32-R, BK1/S506-32-R, GDC-32MA, and S506-32-R are manufactured by Eaton - Electronics Division and provide functional equivalence across all critical parameters. These parts maintain the 32 mA, 250 V, slow-blow, 5x20mm specification set and are active products with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the obsolete Littelfuse 0218.032H. Selection between alternatives is determined by product status, regulatory compliance, and certification requirements.

Littelfuse Series 218 Variants (0218.032HXP, 0218.032MXBP, 0218.032MXP, 0218.032TXP, 0218.032VXP): All are active products with ROHS3 compliance and extended certification coverage including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. These parts are recommended for applications requiring current regulatory compliance and extended international certification support.

Eaton Series GDC (BK/GDC-32MA, GDC-32MA): Active products with RoHS compliance and cULus or cURus certification. Suitable for applications requiring Eaton component qualification.

Eaton Series S506 (BK/S506-32-R, BK1/S506-32-R, S506-32-R): Active products with ROHS3 compliance and comprehensive international certification including BSI, CCC, IMQ, SEMKO, UL, and VDE. These parts provide the broadest certification coverage among Eaton alternatives.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used interchangeably with the Littelfuse 0218.032H?

A: All listed substitute parts maintain identical current rating (32 mA), voltage rating (250 V AC), response characteristic (slow-blow), and physical form factor (5mm x 20mm). They are electrically and mechanically interchangeable within the same fuse holder assembly.

Q: What is the difference between Littelfuse Series 218 variants (HXP, MXBP, MXP, TXP, VXP)?

A: The variants represent different packaging designations and minor variations in DC cold resistance and melting I²t values. All maintain the core 32 mA, 250 V, slow-blow specification. Selection between variants is based on packaging requirements and specific certification needs for the application.

Q: Are there differences in certification between Littelfuse and Eaton alternatives?

A: Littelfuse Series 218 parts carry certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Eaton Series GDC parts carry cULus or cURus and IMQ certifications. Eaton Series S506 parts carry BSI, CCC, IMQ, SEMKO, UL, and VDE certifications. Application requirements determine which certification set is necessary.

Q: Does the fuse holder remain the same for all substitute parts?

A: Yes. All substitute parts are 5mm x 20mm glass cartridge fuses requiring a holder. The existing fuse holder assembly is compatible with all listed alternatives.

Q: What is the significance of RoHS compliance for these parts?

A: The original Littelfuse 0218.032H is RoHS non-compliant. All active substitute parts are RoHS or ROHS3 compliant, meeting current environmental and regulatory requirements for new equipment designs and procurement.
