BK/GDA-315MA Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The BK/GDA-315MA is a 315 mA ceramic fuse cartridge rated for 250 V AC/DC operation in a 5mm x 20mm form factor, manufactured by Eaton - Electronics Division. This fast-blow fuse is designed for applications requiring circuit protection with a breaking capacity of 1.5 kA at rated voltage. The part is currently active in production and widely available in inventory. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and approval certifications to ensure direct interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/GDA-315MA ceramic fuse cartridge is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 315 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these critical parameters. Variations in secondary specifications such as DC cold resistance, melting I²t values, operating temperature ranges, and approval agency certifications do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BK/GDA-315MA, 0216.315TXP, and FCD-315MA—are functionally equivalent for circuit protection applications requiring 315 mA fast-blow ceramic fuse cartridges in 5mm x 20mm form factor at 250 V AC operation.

Selection Basis:

BK/GDA-315MA (Eaton - Electronics Division): Primary part with active product status. Approved by CCC, CSA, IMQ, SEMKO, and UL. Suitable for applications requiring UL certification. Current inventory: 759 pcs.

0216.315TXP (Littelfuse Inc.): Direct substitute with active product status. Approved by CCC, CE, CSA, SEMKO, UR, and VDE. Provides broader European compliance (CE, VDE) and extended operating temperature range (-55°C ~ 125°C). Current inventory: 1140 pcs.

FCD-315MA (OptiFuse): Parametric equivalent with active product status. Approved to IEC 60127 standard. Explicitly rated for 250 V DC operation in addition to 250 V AC. Extended operating temperature range (-55°C ~ 125°C). Highest current inventory availability: 2551 pcs.

Selection among these parts should be based on certification requirements specific to the end application, geographic compliance mandates, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 0216.315TXP replace BK/GDA-315MA in all applications?

A: Yes. Both parts share identical current rating (315 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (fast blow), and breaking capacity (1.5 kA). Physical and electrical interchangeability is complete. Certification differences (0216.315TXP includes CE and VDE) may be advantageous in European markets.

Q: What is the difference between FCD-315MA and the other two parts?

A: FCD-315MA is functionally equivalent across all critical parameters. The primary distinction is explicit DC voltage rating (250 V DC) in addition to AC rating, whereas the other parts specify only AC operation. FCD-315MA also has a slightly higher melting I²t value (0.0142 vs. 0.01), which remains within acceptable tolerance for fast-blow ceramic fuse cartridges. All three parts are mechanically and electrically interchangeable.

Q: Are these parts compatible with standard 5mm x 20mm fuse holders?

A: Yes. All three parts require a fuse holder and are designed for standard 5mm x 20mm cartridge fuse holders. Mechanical compatibility is guaranteed across all identified substitutes.

Q: Which part should I select for maximum inventory availability?

A: FCD-315MA (OptiFuse) offers the highest current stock level at 2551 pcs, followed by 0216.315TXP (Littelfuse) at 1140 pcs, and BK/GDA-315MA (Eaton) at 759 pcs.

Q: Do these parts have different approval certifications?

A: Yes. BK/GDA-315MA is approved by CCC, CSA, IMQ, SEMKO, and UL. 0216.315TXP is approved by CCC, CE, CSA, SEMKO, UR, and VDE. FCD-315MA is approved to IEC 60127. Selection should align with specific certification requirements of the target application and geographic market.

Q: Is RoHS compliance consistent across all three parts?

A: All three parts are RoHS compliant. BK/GDA-315MA is RoHS Compliant. Both 0216.315TXP and FCD-315MA are ROHS3 Compliant, representing the current RoHS standard revision.
