Substitute Part Grouping Explanation

Substitution eligibility for the 0BLS005.T is determined by the following critical parameters:

  • Current Rating: 5A (exact match required)
  • Voltage Rating (AC): 600VAC (exact match required)
  • Fuse Type: Cartridge (exact match required)
  • Response Time: Fast Blow (exact match required)
  • Breaking Capacity @ Rated Voltage: 10kA (exact match required)
  • Mounting Type: Requires Holder (exact match required)

The Eaton Bussmann BBS-5 meets all mandatory electrical and mechanical parameters for direct substitution. Both parts share identical current, voltage, response characteristics, and breaking capacity specifications. Physical dimensions are within acceptable tolerance ranges for standard 5AG cartridge fuse holders.

Engineering Selection Recommendations

The Eaton Bussmann BBS-5 is electrically and mechanically equivalent to the Littelfuse 0BLS005.T for applications requiring a 5A 600VAC fast-blow cartridge fuse. Both parts carry CSA and UL certifications, meeting standard industrial approval requirements.

Selection between these parts should consider the following factors:

  • RoHS Compliance: The 0BLS005.T is ROHS3 compliant, while the BBS-5 is RoHS non-compliant. Applications subject to RoHS requirements must use the 0BLS005.T.
  • Regulatory Environment: Both parts maintain REACH Unaffected status. The BBS-5 includes CE certification in addition to CSA and UL approvals.
  • Physical Dimensions: Dimensional tolerances between the two parts are minimal (0.004" diameter difference, 0.005" length difference). Compatibility with existing fuse holders should be verified based on holder specifications.
  • Inventory Availability: The 0BLS005.T has 891 units in stock; the BBS-5 has 765 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the BBS-5 be used as a direct replacement for the 0BLS005.T?

A: The BBS-5 meets all electrical specifications (5A, 600VAC, fast-blow, 10kA breaking capacity) and mounting requirements. Physical dimensions are within acceptable tolerance ranges for standard 5AG cartridge fuse holders. Compatibility depends on the specific fuse holder design and its tolerance specifications.

Q: What are the key differences between these two parts?

A: The primary differences are RoHS compliance status (0BLS005.T is ROHS3 compliant; BBS-5 is non-compliant) and certification scope (BBS-5 includes CE certification). Electrical and mechanical performance characteristics are equivalent.

Q: Are there any dimensional concerns when substituting these parts?

A: The 0BLS005.T measures 0.406" diameter x 1.375" length; the BBS-5 measures 0.410" diameter x 1.380" length. These differences are within typical manufacturing tolerances for 5AG cartridge fuses. Verify compatibility with your specific fuse holder before implementation.

Q: Which part should I select for RoHS-compliant applications?

A: The Littelfuse 0BLS005.T is ROHS3 compliant and must be used for applications subject to RoHS requirements.

Q: Do both parts require the same type of fuse holder?

A: Both parts are cartridge fuses requiring a compatible holder. Standard 5AG fuse holders are designed to accommodate both parts within their tolerance specifications. Consult your fuse holder documentation for specific compatibility confirmation.
