Equivalent & Substitute Parts for F02B250V2AS

Part Overview

The F02B250V2AS is a 2A 250 VAC military-specification fuse cartridge manufactured by Eaton - Bussmann Electrical Division, conforming to MIL-F-15160/02 standards. This component is classified as obsolete, indicating it is no longer in active production. The cartridge requires a compatible holder for installation and operates as a slow-blow fuse in electrical and industrial applications. Due to its obsolete status, identifying functionally equivalent substitute components is necessary for system maintenance, repair, and new design implementations where MIL-F-15160/02 compliance is not mandatory.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the F02B250V2AS is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 2A
• Voltage Rating (AC): 250 VAC
• Response Time: Slow Blow
• Fuse Type: Cartridge
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Physical Dimensions: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Mounting Configuration: Requires Holder

The MDL-2-R cartridge fuse meets all critical parameters and is therefore classified as a direct substitute. Both components share identical electrical ratings, physical form factors, and mounting requirements, enabling direct replacement in holder-based installations.

Parameter Comparison

Engineering Selection Recommendations

The MDL-2-R represents the primary substitute for the obsolete F02B250V2AS based on complete electrical and mechanical parameter equivalence. Both components are 2A 250 VAC slow-blow cartridge fuses with identical physical dimensions and holder-based mounting configurations.

Status Consideration: The F02B250V2AS is obsolete and no longer manufactured. The MDL-2-R is an active product with current manufacturing support and inventory availability.

Compliance Consideration: The MDL-2-R carries CE, CSA, and UL certifications, providing broader regulatory acceptance than the military-specification F02B250V2AS. The MDL-2-R achieves ROHS3 compliance, whereas the F02B250V2AS is RoHS non-compliant. Applications requiring strict MIL-F-15160/02 compliance cannot use the MDL-2-R as a substitute; however, for general electrical and industrial applications, the MDL-2-R provides equivalent protection and performance.

Performance Data: The MDL-2-R provides documented breaking capacity (100A) and melting I²t (62.3), enabling precise circuit protection analysis. These specifications were not provided for the F02B250V2AS.

Frequently Asked Questions (FAQ)

Q: Can the MDL-2-R directly replace the F02B250V2AS in existing installations?

A: Yes, the MDL-2-R is mechanically and electrically compatible with the F02B250V2AS. Both components are 2A 250 VAC slow-blow cartridge fuses with identical 0.250" Dia x 1.250" L dimensions and 3AB/3AG package specifications. Direct installation in existing holders is possible without modification.

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

A: The F02B250V2AS conforms to military specification MIL-F-15160/02 and is obsolete. The MDL-2-R is an active commercial product with CE, CSA, and UL certifications and ROHS3 compliance. Both provide identical electrical protection at 2A 250 VAC with slow-blow response characteristics.

Q: Are there applications where the MDL-2-R cannot substitute for the F02B250V2AS?

A: Applications requiring strict adherence to MIL-F-15160/02 military specifications cannot use the MDL-2-R as a substitute. For general electrical and industrial applications without military specification requirements, the MDL-2-R is a suitable replacement.

Q: What certifications does the MDL-2-R carry?

A: The MDL-2-R holds CE, CSA, and UL certifications, providing compliance with European, Canadian, and United States safety standards. The component is ROHS3 compliant and REACH unaffected.

Q: Is the MDL-2-R available in inventory?

A: Yes, 724 pieces of the MDL-2-R are available as new original stock in bulk packaging.

Q: Do both fuses have the same physical dimensions?

A: Yes, both the F02B250V2AS and MDL-2-R measure 0.250" diameter by 1.250" length (6.35mm x 31.75mm) and conform to 3AB and 3AG package standards, ensuring compatibility with standard cartridge fuse holders.
