Substitute Part Grouping Explanation

Substitution eligibility for the 0216.050MXGP is determined by strict equivalence across the following parameters:

Current Rating: 50 mA (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)
Response Time: Fast Blow (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)
Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these criteria. Littelfuse parts 0216.050HXP and 0216.050MXP are parametric equivalents within the same manufacturer series. Eaton GDA-50MA and BK/GDA-50MA are manufacturer-recommended alternatives from a different manufacturer, maintaining identical electrical and mechanical specifications.

Engineering Selection Recommendations

All identified substitute parts are active products with current manufacturing status and full regulatory compliance. Selection between Littelfuse and Eaton alternatives should be based on:

Regulatory certification requirements for the target application (Littelfuse parts carry VDE certification; Eaton GDA-50MA carries UR certification; Eaton BK/GDA-50MA carries UL certification)
Inventory availability and lead time requirements
Existing supply chain qualification and procurement agreements
DC cold resistance specifications if critical to application performance (Littelfuse: 15.9 Ohms; Eaton: 157.5 Ohms)

All parts meet identical electrical and mechanical specifications for direct substitution in 5x20mm fuse holder applications rated for 50mA, 250VAC fast-blow protection.

Frequently Asked Questions (FAQ)

Q: Can 0216.050HXP and 0216.050MXP be used interchangeably with 0216.050MXGP?

A: Yes. These Littelfuse parts are parametric equivalents with identical current rating, voltage rating, fuse type, response time, package dimensions, breaking capacity, and mounting requirements. All three parts are ROHS3 compliant and carry the same regulatory certifications.

Q: Are Eaton GDA-50MA and BK/GDA-50MA suitable replacements?

A: Yes. Both Eaton parts meet all electrical and mechanical specifications. The primary difference is regulatory certification: GDA-50MA carries UR certification, while BK/GDA-50MA carries UL certification. Verify that the target application's certification requirements align with the selected part.

Q: What is the significance of DC cold resistance differences between Littelfuse and Eaton parts?

A: Littelfuse parts specify 15.9 Ohms DC cold resistance, while Eaton parts specify 157.5 Ohms. This parameter is provided in the technical data but does not affect substitution eligibility for standard circuit protection applications. Confirm DC cold resistance requirements with application-specific design specifications if this parameter is critical.

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

A: Yes. All parts are 5mm x 20mm ceramic cartridge fuses requiring a standard 5x20mm fuse holder. No holder modifications are necessary when substituting between these parts.

Q: What inventory considerations apply to these substitutes?

A: Current stock levels are: 0216.050MXP (1701 units), GDA-50MA (1158 units), 0216.050HXP (852 units), BK/GDA-50MA (839 units), and 0216.050MXGP (778 units). Inventory availability may influence procurement decisions for time-sensitive applications.
