Littelfuse 0216.100MXP Ceramic Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.100MXP is a 100 mA, 250 V AC/DC ceramic fuse cartridge with fast-blow response characteristics. The component is housed in a 5mm x 20mm form factor and requires a compatible fuse holder for installation. This part maintains active product status and is fully compliant with RoHS3 standards. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category, enabling direct functional replacement in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: current rating (100 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), and physical package dimensions (5mm x 20mm). All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the same circuit protection application.

The substitute parts are categorized as follows:

• Direct Manufacturer Equivalents (Littelfuse Series 216): Parts 0216.100HXP and 0216.100TXP are Littelfuse products within the same 216 series, sharing identical electrical parameters and operating temperature range.

• Cross-Manufacturer Equivalents (Eaton Electronics Division): Parts BK/S501-100-R, S501-100-R, and GDA-100MA are Eaton-manufactured ceramic fuse cartridges meeting the same electrical specifications and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and RoHS3 compliance. Selection between Littelfuse Series 216 parts (0216.100HXP, 0216.100TXP) and the original 0216.100MXP is determined by availability and inventory requirements, as these parts are electrically and mechanically identical.

Cross-manufacturer substitution with Eaton products (BK/S501-100-R, S501-100-R, GDA-100MA) is permissible based on equivalent electrical parameters and package dimensions. Certification requirements should be verified against application-specific regulatory standards. The Littelfuse parts carry broader approval agency coverage (CCC, CE, CSA, SEMKO, UR, VDE), while Eaton parts carry CSA and UR certifications.

Frequently Asked Questions (FAQ)

Q: Can I use 0216.100HXP or 0216.100TXP as direct replacements for 0216.100MXP?

A: Yes. These Littelfuse Series 216 parts are electrically and mechanically identical to the 0216.100MXP, sharing the same current rating, voltage rating, response time, package dimensions, and operating temperature range.

Q: Are Eaton S501 and GDA series fuses compatible with the 0216.100MXP?

A: Yes, from an electrical and mechanical standpoint. All parts maintain 100 mA current rating, 250 V AC voltage rating, fast-blow response, and 5mm x 20mm package dimensions. Certification differences should be evaluated against application requirements.

Q: What is the significance of the different Melting I²t values?

A: Littelfuse parts (0216.100MXP, 0216.100HXP, 0216.100TXP) have a Melting I²t of 0.0045, while Eaton parts have 0.0018. Both values are provided as part of the technical specification; selection should be based on application thermal requirements and circuit protection design parameters.

Q: Do all substitute parts require the same fuse holder?

A: Yes. All identified substitute parts share the 5mm x 20mm package dimension and require a compatible 5mm x 20mm fuse holder. Physical installation is identical across all parts.

Q: Which parts have the broadest regulatory approval coverage?

A: The Littelfuse Series 216 parts (0216.100MXP, 0216.100HXP, 0216.100TXP) carry approvals from CCC, CE, CSA, SEMKO, UR, and VDE. Eaton parts carry CSA and UR certifications (with some variants including cULus or cURus). Application-specific regulatory requirements should determine final part selection.
