Equivalent & Substitute Parts for BK/C515-600MA

Part Overview

The BK/C515-600MA is a 600 mA, 250 V AC/DC slow-blow glass cartridge fuse in 2AG package format (5mm x 15mm axial). Manufactured by Eaton Electronics Division, this component is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active product lines are necessary to maintain circuit protection functionality in applications requiring 600 mA fusing at 250 V AC ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/C515-600MA is determined by the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 600 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Through Hole (exact match required)
• Approval Agencies: CSA and/or UL certification (required for safety compliance)

Acceptable Variation Parameters:

• Package / Case: 2AG format with axial orientation; minor dimensional variations within 5mm x 15mm specification are acceptable
• Voltage Rating (DC): Additional DC voltage rating does not disqualify a substitute for AC-only applications
• Melting I²t: Variations in melting I²t are acceptable provided current and voltage ratings remain identical
• DC Cold Resistance: Minor variations in resistance are acceptable
• RoHS Compliance: Substitutes may have improved RoHS compliance status compared to the obsolete main part

Substitute parts are grouped into two categories: direct equivalents from the same manufacturer (Eaton C515 series) and parametric equivalents from alternative manufacturers (Littelfuse 230 series) that meet all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Eaton C515 Series):

BK/C515-600-R and BK/C515S-600-R are direct equivalents manufactured by Eaton Electronics Division. Both parts maintain identical electrical specifications (600 mA, 250 V AC, slow-blow response, 35A breaking capacity) and mechanical form factor (2AG, 5mm x 15mm axial) as the obsolete BK/C515-600MA. Both are active products with RoHS compliance, making them the preferred substitutes for direct replacement in existing designs. The primary difference between these two Eaton equivalents is packaging format (bulk vs. standard).

Parametric Equivalents (Littelfuse 230 Series):

The Littelfuse 230 series parts (0230.600DRT1P, 0230.600DRT2P, 0230.600DRT3P, 0230.600HXP, 0230.600MXP, 0230.600VXP) meet all critical electrical parameters for 600 mA, 250 V AC slow-blow fusing. These parts carry CSA and UL certifications equivalent to the main part. The Littelfuse parts feature enhanced DC voltage rating (125 V DC) and higher DC breaking capacity (10kA DC), providing additional protection margin in mixed AC/DC applications. All Littelfuse substitutes are active products with ROHS3 compliance. Physical dimensions are slightly smaller (4.50mm x 14.50mm) compared to the 2AG standard, requiring verification of mechanical fit in existing fuse holders or PCB layouts.

Selection Basis:

• For direct form-factor replacement: Select BK/C515-600-R or BK/C515S-600-R
• For applications requiring enhanced DC specifications: Select Littelfuse 230 series parts
• All recommended substitutes maintain CSA and UL approval certifications
• All recommended substitutes are active products with current manufacturing support

Frequently Asked Questions (FAQ)

Q: Can BK/C515-600-R be used as a direct replacement for BK/C515-600MA?

A: Yes. BK/C515-600-R is a direct equivalent with identical electrical ratings (600 mA, 250 V AC, slow-blow response) and mechanical specifications (2AG, 5mm x 15mm axial). The primary difference is that BK/C515-600-R is an active product with RoHS compliance, whereas BK/C515-600MA is obsolete and RoHS non-compliant.

Q: What is the difference between BK/C515-600-R and BK/C515S-600-R?

A: Both parts are electrically and mechanically identical. The difference is in packaging format: BK/C515-600-R is supplied in bulk packaging, while BK/C515S-600-R is supplied in standard packaging. Both are active Eaton products with RoHS compliance and identical electrical specifications.

Q: Can Littelfuse 230 series parts substitute for the BK/C515-600MA?

A: Yes, with physical fit verification. Littelfuse 230 series parts (0230.600DRT1P, 0230.600DRT2P, 0230.600DRT3P, 0230.600HXP, 0230.600MXP, 0230.600VXP) meet all critical electrical parameters: 600 mA current rating, 250 V AC voltage rating, and slow-blow response. All carry CSA and UL certifications. However, Littelfuse parts have slightly smaller dimensions (4.50mm x 14.50mm vs. 5mm x 15mm 2AG standard), requiring confirmation that existing fuse holders or PCB layouts accommodate the smaller cartridge.

Q: What are the key electrical parameters that must match for substitution?

A: The following parameters must match exactly: current rating (600 mA), AC voltage rating (250 V), fuse type (cartridge glass), response time (slow blow), and mounting type (through hole). Additional DC voltage rating and enhanced breaking capacity do not disqualify a substitute.

Q: Are all recommended substitutes certified by CSA and UL?

A: Yes. All recommended substitutes carry CSA and UL certifications, meeting the approval requirements of the original BK/C515-600MA.

Q: What is the difference in melting I²t between the Eaton and Littelfuse substitutes?

A: The Eaton C515 series (BK/C515-600-R, BK/C515S-600-R) has a melting I²t of 6.982, while the Littelfuse 230 series has a melting I²t of 1.75. Both values are acceptable for 600 mA slow-blow fuses at 250 V AC. The difference reflects different thermal characteristics but does not affect substitutability for the specified current and voltage ratings.

Q: Do Littelfuse 230 series parts have any advantages over Eaton C515 equivalents?

A: Littelfuse 230 series parts feature a rated DC voltage of 125 V and DC breaking capacity of 10kA, compared to the Eaton parts which do not specify DC ratings. This provides additional protection margin in applications with mixed AC/DC exposure. All Littelfuse substitutes are ROHS3 compliant. The trade-off is slightly smaller physical dimensions requiring mechanical fit verification.

Q: What packaging options are available for these substitutes?

A: Eaton C515-600-R is supplied in bulk packaging. Littelfuse 230 series parts are available in multiple packaging formats: tape and reel (0230.600DRT1P, 0230.600DRT2P, 0230.600DRT3P) and bulk (0230.600HXP, 0230.600MXP, 0230.600VXP). Selection depends on procurement and assembly requirements.
