GDA-50MA Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The GDA-50MA is a 50 mA ceramic fuse cartridge rated for 250 V AC/DC operation in a 5mm x 20mm package form factor. This fast-blow fuse requires a compatible holder for installation and is designed for circuit protection applications requiring rapid response to overcurrent conditions. The part maintains active product status with 1158 pieces in current inventory. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and approval certifications to ensure direct functional interchangeability in protected circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GDA-50MA is determined by strict equivalence across the following critical parameters:

Current Rating: All substitute parts must be rated at 50 mA to provide identical overcurrent protection threshold.

Voltage Rating (AC): All substitute parts must be rated at 250 V AC to match the electrical environment specification.

Fuse Type & Response Time: All substitute parts must be ceramic cartridge fuses with fast-blow response characteristics to maintain circuit protection behavior.

Package / Case Dimensions: All substitute parts must conform to the 5mm x 20mm physical envelope to ensure mechanical compatibility with existing fuse holders.

Breaking Capacity: All substitute parts must maintain 1.5 kA breaking capacity at rated voltage to handle fault current interruption requirements.

The following parts meet these substitution criteria:

• BK/GDA-50MA (Eaton - Electronics Division)
• 0216.050HXP (Littelfuse Inc.)
• 0216.050MXP (Littelfuse Inc.)

Parameter Comparison

Engineering Selection Recommendations

All four parts listed maintain active product status and are suitable for direct substitution based on electrical and mechanical parameter equivalence. Selection between these parts may be influenced by the following factors:

Approval Certifications: The GDA-50MA and BK/GDA-50MA carry CCC, CSA, IMQ, SEMKO, and UR certifications. The 0216.050HXP and 0216.050MXP carry CCC, CE, CSA, SEMKO, UR, and VDE certifications. Applications requiring specific regional compliance (such as CE marking for European markets or VDE certification) should reference the required approval agencies for the target application.

Inventory Availability: The 0216.050MXP offers the highest current inventory at 1701 pieces. The GDA-50MA maintains 1158 pieces, while BK/GDA-50MA and 0216.050HXP each maintain approximately 839-852 pieces.

RoHS Compliance: The BK/GDA-50MA is RoHS Compliant. The 0216.050HXP and 0216.050MXP are ROHS3 Compliant. The GDA-50MA RoHS status is not specified in the provided data.

Operating Temperature Range: The 0216.050HXP and 0216.050MXP specify an operating temperature range of -55°C to 125°C. The GDA-50MA and BK/GDA-50MA do not specify operating temperature limits in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the BK/GDA-50MA be used as a direct replacement for the GDA-50MA?

A: Yes. Both parts are manufactured by Eaton - Electronics Division, share the GDA series designation, and match all critical electrical parameters (50 mA current rating, 250 V AC voltage rating, fast-blow response) and mechanical dimensions (5mm x 20mm). Both require a compatible fuse holder for installation.

Q: What is the difference between the Littelfuse 0216.050HXP and 0216.050MXP?

A: Both parts are electrically and mechanically equivalent, sharing identical current rating (50 mA), voltage rating (250 V AC), fuse type (ceramic cartridge, fast-blow), package dimensions (5mm x 20mm), and breaking capacity (1.5 kA). Both are ROHS3 Compliant and carry CE, CCC, CSA, SEMKO, UR, and VDE certifications. The primary difference is inventory availability, with the 0216.050MXP maintaining higher stock levels (1701 pieces versus 852 pieces).

Q: Are these fuses compatible with existing GDA-50MA fuse holders?

A: Yes. All substitute parts conform to the 5mm x 20mm package dimension specification and are designed as cartridge fuses requiring a compatible holder. Mechanical compatibility is ensured through dimensional equivalence.

Q: Which substitute part should be selected for European applications?

A: The 0216.050HXP and 0216.050MXP both carry VDE and CE certifications, making them suitable for European market requirements. The Littelfuse 216 series parts provide explicit compliance documentation for European standards.

Q: Do all substitute parts have the same melting I²t value?

A: No. The GDA-50MA and BK/GDA-50MA specify a melting I²t of 0.0017. The 0216.050HXP and 0216.050MXP specify a melting I²t of 0.00019. Despite this difference, all parts maintain the same 50 mA current rating, 250 V voltage rating, and 1.5 kA breaking capacity, confirming electrical equivalence for circuit protection applications.

Q: What is the DC cold resistance specification for these fuses?

A: The GDA-50MA and BK/GDA-50MA specify 157.5 Ohms DC cold resistance. The 0216.050HXP and 0216.050MXP specify 15.9 Ohms DC cold resistance. Both values are within acceptable ranges for ceramic cartridge fuses and do not affect functional substitution capability.
