Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAF-5 is determined by strict equivalence across the following critical parameters:

• Current Rating: 5A (exact match required)
• Voltage Rating: 250VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5AG, 10mm x 38mm Midget (exact match required)
• Physical Dimensions: 0.406" Dia x 1.500" L (exact match required)
• Mounting Configuration: Requires Holder (exact match required)

The substitute part 0BLF005.T manufactured by Littelfuse Inc. meets all critical electrical and mechanical parameters, enabling direct functional replacement in applications currently using the BAF-5.

Parameter Comparison

Engineering Selection Recommendations

Both the BAF-5 and 0BLF005.T are active products with established supply availability. The BAF-5 carries CE, CSA, and UL certifications. The 0BLF005.T carries CSA and UL certifications with ROHS3 compliance. Selection between these parts should be based on specific application requirements regarding regulatory compliance, RoHS status, and breaking capacity specifications. The 0BLF005.T provides higher breaking capacity (10kA versus 200A) and improved environmental compliance through ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can the 0BLF005.T directly replace the BAF-5 in existing installations?

A: Yes. Both fuses share identical electrical ratings (5A, 250VAC), response characteristics (fast blow), and mechanical specifications (5AG cartridge, 10mm x 38mm dimensions). Both require the same holder configuration.

Q: What is the significance of the different breaking capacity ratings?

A: The BAF-5 has a breaking capacity of 200A, while the 0BLF005.T has 10kA. Breaking capacity indicates the maximum fault current the fuse can safely interrupt. The 0BLF005.T provides higher fault current handling capability.

Q: Are there regulatory compliance differences between these parts?

A: The BAF-5 is RoHS non-compliant. The 0BLF005.T is ROHS3 compliant. Applications requiring RoHS compliance must use the 0BLF005.T. Both parts carry UL and CSA certifications; the BAF-5 additionally carries CE certification.

Q: Do these fuses use the same holder?

A: Yes. Both are 5AG cartridge fuses with identical 10mm x 38mm dimensions and require the same holder type.

Q: What is the difference in DC cold resistance?

A: The 0BLF005.T specifies DC cold resistance of 0.0413 Ohms. This parameter is not provided for the BAF-5 in the available data.
