Key Parameters

Substitute Part Grouping Explanation

Substitution of the F03A250V3AS is determined by strict alignment of the following parameters:

• Voltage Rating: 250V AC/DC operation
• Package / Case: 3AB, 3AG form factor
• Physical Dimensions: 0.250" diameter × 1.250" length (6.35mm × 31.75mm)
• Mounting Configuration: Requires holder installation
• Product Status: Active availability

The substitute part BK/AGC-3-R meets all these criteria and is therefore electrically and mechanically compatible with the F03A250V3AS.

Parameter Comparison

Engineering Selection Recommendations

Both the F03A250V3AS and BK/AGC-3-R are active products from Eaton with identical physical form factors and voltage ratings. The BK/AGC-3-R offers ROHS3 compliance, whereas the F03A250V3AS is RoHS non-compliant. Selection between these parts should be based on regulatory requirements specific to the application. Both parts carry CSA and UL approvals for the BK/AGC-3-R variant, ensuring compliance with recognized safety standards. Inventory availability of 6557 units for BK/AGC-3-R versus 903 units for F03A250V3AS may influence procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-3-R be used as a direct replacement for F03A250V3AS?

A: Yes. Both fuses share identical package specifications (3AB, 3AG), physical dimensions (0.250" Dia × 1.250" L), voltage rating (250V), and mounting requirements (requires holder). They are mechanically and electrically interchangeable.

Q: What is the primary difference between these two fuses?

A: The BK/AGC-3-R is ROHS3 compliant, while the F03A250V3AS is RoHS non-compliant. The BK/AGC-3-R also specifies a 3A current rating and includes CSA/UL approvals.

Q: Are there any compatibility concerns with existing holders?

A: No. Both fuses use the same 3AB and 3AG package form factors with identical dimensions, ensuring compatibility with any holder designed for these specifications.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring RoHS compliance, the BK/AGC-3-R is the appropriate choice. For applications without RoHS requirements, either part is suitable based on availability and cost considerations.
