Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FWH-025A6FR is determined by the following critical parameters:

• Current Rating: 25A (exact match required)
• Voltage Rating - AC: 500 VAC (exact match required)
• Physical Dimensions: 0.252" Dia x 1.252" L (6.40mm x 31.80mm) (exact match required for holder compatibility)
• Mounting Type: Requires Holder (must be compatible with existing holder installations)
• Fuse Type: Cartridge (mechanical and electrical compatibility)

The substitute part BK-ADC-25-R meets all critical substitution criteria. This part is manufactured by Eaton - Electronics Division and shares identical current rating, AC voltage rating, and physical dimensions with the main part. Both components are cartridge-style fuses requiring holder-based mounting and maintain Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the FWH-025A6FR and BK-ADC-25-R maintain Active product status and are manufactured by Eaton divisions, ensuring supply chain continuity. The FWH-025A6FR carries CE, CSA, and UR approvals with confirmed RoHS compliance. The BK-ADC-25-R carries cURus and UL approvals, providing alternative certification pathways for applications requiring specific regulatory compliance.

Selection between these parts should be based on:

• Regulatory approval requirements specific to the application jurisdiction
• Existing holder compatibility and installation infrastructure
• DC voltage rating requirements (BK-ADC-25-R provides 500 VDC capability)
• Breaking capacity specifications for the circuit protection scheme

Both parts share identical current rating, AC voltage rating, and physical dimensions, confirming mechanical and electrical interchangeability within holder-based installations.

Frequently Asked Questions (FAQ)

Q: Can BK-ADC-25-R be used as a direct replacement for FWH-025A6FR?

A: Yes, within the constraints of holder compatibility and regulatory approval requirements. Both parts share identical current rating (25A), AC voltage rating (500 VAC), and physical dimensions (0.252" Dia x 1.252" L). Verify that the existing holder is compatible with both cartridge styles before installation.

Q: What is the difference between the ceramic construction of BK-ADC-25-R and the standard cartridge construction of FWH-025A6FR?

A: The BK-ADC-25-R uses ceramic construction, which is specified in the product data. Both parts meet the same current and voltage ratings and share identical physical dimensions for holder compatibility.

Q: Are there differences in approval certifications between these parts?

A: Yes. FWH-025A6FR carries CE, CSA, and UR approvals. BK-ADC-25-R carries cURus and UL approvals. Select the part that matches your application's regulatory requirements.

Q: Does BK-ADC-25-R offer any performance advantages?

A: BK-ADC-25-R provides a higher breaking capacity at rated AC voltage (30kA versus 20kA) and includes 500 VDC rating capability, which may be beneficial for applications requiring DC circuit protection or higher fault current handling.

Q: Are both parts currently available?

A: Yes. FWH-025A6FR has 887 units in inventory. BK-ADC-25-R has 1544 units in inventory, both listed as Active products.
