Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/GDB-V-3.15A are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Current Rating: 3.15 A
• Voltage Rating (AC): 250 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 35 A

Mechanical Parameters (Must Match):

• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole
• Fuse Type: Cartridge, Glass

Compliance Parameters (Must Be Present):

• Product Status: Active
• RoHS Compliance: Required

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the original part in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BK/GDB-V-3.15A (Eaton), 0034.1521.PT (SCHURTER), and 02173.15MXEP (Littelfuse)—are Active status products with current RoHS compliance certifications. Each part satisfies the core electrical and mechanical requirements for direct substitution.

Eaton BK/GDB-V-3.15A: Original specification part with UL and VDE approvals. Melting I²t of 13 represents the fastest thermal response among the three options.

SCHURTER 0034.1521.PT: cURus approved substitute with operating temperature range of -55°C to 125°C. Melting I²t of 16.1 provides intermediate thermal response. ROHS3 compliant with REACH Unaffected status.

Littelfuse 02173.15MXEP: Broadest approval agency coverage including BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE. Operating temperature range of -55°C to 125°C. Melting I²t of 17.72 represents the slowest thermal response. ROHS3 compliant with REACH Unaffected status and MSL rating of 1 (Unlimited).

Selection among these parts depends on application-specific requirements for thermal response characteristics, operating temperature environment, and required regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can 0034.1521.PT (SCHURTER) be used as a direct replacement for BK/GDB-V-3.15A (Eaton)?

A: Yes. Both parts share identical electrical ratings (3.15 A, 250 V AC), fuse type (cartridge, glass), response time (fast blow), and mechanical package (5mm x 20mm axial through-hole). Dimensional variations (0.213" Dia x 0.886" L versus 0.218" Dia x 0.831" L) remain within acceptable mechanical tolerances for standard fuse holders. Both are Active status with current RoHS compliance.

Q: Can 02173.15MXEP (Littelfuse) be used as a direct replacement for BK/GDB-V-3.15A (Eaton)?

A: Yes. Both parts meet identical electrical specifications (3.15 A, 250 V AC), fuse type (cartridge, glass), response time (fast blow), and mechanical package (5mm x 20mm axial through-hole). Dimensional variations (0.228" Dia x 0.886" L versus 0.218" Dia x 0.831" L) remain within acceptable mechanical tolerances for standard fuse holders. Both are Active status with current RoHS compliance.

Q: What is the difference in melting I²t values among these parts?

A: Melting I²t indicates thermal response speed. BK/GDB-V-3.15A has I²t of 13, 0034.1521.PT has I²t of 16.1, and 02173.15MXEP has I²t of 17.72. Lower I²t values indicate faster thermal response to overcurrent conditions. All three parts are classified as fast-blow fuses and are electrically equivalent for the specified 3.15 A rating.

Q: Are there operating temperature differences among these substitutes?

A: BK/GDB-V-3.15A does not specify an operating temperature range. Both 0034.1521.PT and 02173.15MXEP specify -55°C to 125°C operating temperature range. For applications requiring extended temperature operation, SCHURTER or Littelfuse parts are appropriate selections.

Q: What are the approval agency differences?

A: BK/GDB-V-3.15A carries UL and VDE approvals. 0034.1521.PT carries cURus approvals. 02173.15MXEP carries the broadest approval coverage: BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE. Application requirements for specific regional certifications determine appropriate part selection.

Q: Are all three parts RoHS compliant?

A: Yes. BK/GDB-V-3.15A is RoHS Compliant. Both 0034.1521.PT and 02173.15MXEP are ROHS3 Compliant. All three parts meet current RoHS requirements.
