Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0BLS001.T is determined by the following critical parameters:

• Current Rating: Must be 1A
• Voltage Rating (AC): Must be 600VAC
• Fuse Type: Must be Cartridge
• Response Time: Must be Fast Blow
• Breaking Capacity: Must be 10kA at rated voltage
• Approval Agencies: Must include CSA and/or UL certification
• RoHS Compliance: Must meet RoHS requirements

The substitute part BBS-1 (Eaton - Bussmann Electrical Division) meets all electrical and mechanical compatibility criteria. Both parts are cartridge fuses with identical current and voltage ratings, fast-blow response characteristics, and equivalent breaking capacity. Physical dimensions are within acceptable tolerance for standard 5AG/midget cartridge holders. Both parts carry appropriate regulatory approvals for industrial and electrical applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0BLS001.T and BBS-1 are active production components with full regulatory compliance. The 0BLS001.T carries CSA and UL approvals; the BBS-1 carries CE, CSA, and UL approvals, providing broader geographic certification coverage. Physical dimensions are within standard tolerance for 5AG midget cartridge holders, ensuring mechanical compatibility. Both parts are RoHS compliant and REACH unaffected, meeting environmental regulatory requirements. Selection between these parts may be based on availability, lead time, or regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can BBS-1 be used as a direct replacement for 0BLS001.T?

A: Yes. Both parts are 1A 600VAC fast-blow cartridge fuses with 10kA breaking capacity. Physical dimensions are compatible with standard 5AG midget cartridge holders. Electrical performance and response characteristics are equivalent.

Q: Are there dimensional differences between these parts?

A: Dimensions are within acceptable tolerance. The 0BLS001.T measures 0.406" diameter x 1.375" length; the BBS-1 measures 0.410" diameter x 1.380" length. These minor variations are within standard cartridge fuse manufacturing tolerances and do not affect holder compatibility.

Q: What approval certifications does each part carry?

A: The 0BLS001.T carries CSA and UL certifications. The BBS-1 carries CE, CSA, and UL certifications. Both meet the primary industrial and electrical safety standards required for 600VAC applications.

Q: Are both parts RoHS compliant?

A: Yes. The 0BLS001.T is ROHS3 compliant; the BBS-1 is RoHS compliant. Both meet environmental compliance requirements for electronic components.

Q: What is the breaking capacity of these fuses?

A: Both parts have a breaking capacity of 10kA at rated voltage (600VAC), indicating their ability to safely interrupt fault currents up to this level.
