Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/C515-2-R are identified based on matching the following critical electrical and mechanical parameters:

Matched Parameters:

• Current Rating: 2 A
• Voltage Rating - AC: 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Approval Agencies: CSA and UL certification

Parameter Variations in Substitutes:

• Voltage Rating - DC: Substitute parts specify 125 V DC rating, whereas the main part does not specify a DC voltage rating
• Package / Case: Substitute parts use a non-standard axial cartridge format (4.50mm x 14.50mm) compared to the standard 2AG format (5.50mm x 15.20mm)
• Breaking Capacity: Substitute parts specify 35A AC and 10kA DC, whereas the main part specifies 100A at rated voltage
• Melting I²t: Substitute parts specify 30 compared to the main part specification of 60.256
• DC Cold Resistance: Substitute parts specify 0.0698 Ohms compared to the main part specification of 0.059 Ohms
• Packaging Format: One substitute part is available in Cut Tape (CT) format; others are in Bulk format

Substitution is permissible when the application circuit operates exclusively at 250 V AC and does not require DC voltage operation, and when the physical dimensions of the non-standard axial cartridge format are compatible with the circuit board layout.

Engineering Selection Recommendations

0230002.MXP (Littelfuse Inc.) - Primary Substitute

The 0230002.MXP is the preferred substitute for the BK/C515-2-R when inventory availability is a consideration. This part maintains identical electrical specifications for 2 A at 250 V AC operation and carries CSA and UL certifications matching the original part. The part is available in bulk packaging with the highest inventory level (34,412 pieces). The non-standard axial cartridge format requires physical verification of circuit board compatibility due to dimensional differences (4.50mm x 14.50mm versus 5.50mm x 15.20mm). This part is ROHS3 compliant and suitable for applications operating exclusively in AC mode.

0230002.HXP (Littelfuse Inc.) - Secondary Substitute

The 0230002.HXP provides equivalent electrical performance with CSA and UL certifications. This part is suitable for applications requiring the same 2 A, 250 V AC specifications. Physical compatibility with the circuit board layout must be confirmed due to the non-standard axial cartridge dimensions. Inventory availability is adequate at 3,311 pieces in bulk format.

0230002.DRT1P (Littelfuse Inc.) - Packaging Alternative

The 0230002.DRT1P is electrically identical to the other Littelfuse substitutes but is supplied in Cut Tape (CT) packaging format. This option is applicable when automated assembly processes require tape-and-reel format. Physical compatibility with the circuit board layout must be confirmed due to dimensional differences from the standard 2AG format.

Critical Compatibility Considerations:

All Littelfuse substitutes feature a non-standard axial cartridge package measuring 4.50mm x 14.50mm, which differs from the standard 2AG format of the original part (5.50mm x 15.20mm). Circuit board footprint and mechanical clearance must be verified before selection. The substitute parts specify 125 V DC rating, whereas the original part does not specify a DC voltage rating. Applications requiring DC operation should confirm that 125 V DC is sufficient for the intended circuit. The breaking capacity of substitute parts (35A AC, 10kA DC) is lower than the original part (100A), which may affect circuit protection characteristics in high-fault-current environments.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0230002.MXP be used as a direct replacement for the Eaton BK/C515-2-R?

A: The 0230002.MXP is electrically compatible for 2 A, 250 V AC applications and carries matching CSA and UL certifications. However, the physical package dimensions differ (4.50mm x 14.50mm versus 5.50mm x 15.20mm). Circuit board footprint compatibility must be verified before installation.

Q: What is the significance of the DC voltage rating difference?

A: The original BK/C515-2-R does not specify a DC voltage rating, while the Littelfuse substitutes specify 125 V DC. For applications operating exclusively at 250 V AC, this difference is not relevant. For circuits with DC components, the 125 V DC rating of the substitutes must be confirmed as adequate for the application.

Q: Are all three Littelfuse parts electrically equivalent?

A: Yes. The 0230002.HXP, 0230002.MXP, and 0230002.DRT1P are electrically identical, each rated at 2 A, 250 V AC with slow-blow response characteristics. The primary differences are packaging format (bulk versus cut tape) and inventory availability.

Q: Why do the substitute parts have lower breaking capacity than the original?

A: The Littelfuse substitutes specify 35A AC and 10kA DC breaking capacity, compared to the original part's 100A specification. This difference reflects the design characteristics of the non-standard axial cartridge format. Applications in high-fault-current environments should evaluate whether this reduced breaking capacity is acceptable.

Q: Which substitute part should be selected for automated assembly?

A: The 0230002.DRT1P is supplied in Cut Tape (CT) format, which is compatible with automated pick-and-place assembly equipment. The 0230002.HXP and 0230002.MXP are available in bulk format for manual assembly or reel-fed processes.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Littelfuse substitutes are ROHS3 compliant, meeting the same environmental standards as the original BK/C515-2-R, which is RoHS compliant.

Q: What certifications do the substitute parts carry?

A: The Littelfuse substitutes carry CE, CSA, PSE, and UL certifications. The original part carries CSA and UL certifications. The additional CE and PSE certifications on the substitutes provide broader regulatory coverage for international applications.
