Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AG50 is determined by the following critical parameters:

• Fuse Class: Must be Class G to ensure compatibility with Class G fuse holders and circuit protection requirements
• Breaking Capacity: Must meet or exceed 100kA at rated voltage
• Voltage Rating: Must support 480V AC operation
• Current Rating: The substitute part 0SLC050.T is rated at 50A, which aligns with the AG50 amperage specification
• Product Status: Active status ensures ongoing availability and manufacturer support
• Compliance: ROHS3 compliance maintains regulatory alignment

The 0SLC050.T from Littelfuse Inc. qualifies as a substitute based on matching Class G specification, 100kA breaking capacity at 480VAC, and ROHS3 compliance. Both parts are active products with established supply chains.

Parameter Comparison

Engineering Selection Recommendations

Both the AG50 and 0SLC050.T are active products with ROHS3 compliance and matching electrical specifications for Class G fuse applications at 480V with 100kA breaking capacity. The 0SLC050.T carries additional certifications including CE, CSA, QPL, and UL approval, providing expanded regulatory coverage for industrial and electrical applications. The primary distinction is packaging format: the AG50 is supplied in box packaging, while the 0SLC050.T is supplied in bulk and requires a separate fuse holder. Selection between these parts should be based on existing holder compatibility, packaging requirements, and certification needs for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 0SLC050.T directly replace the AG50 in existing installations?

A: The 0SLC050.T is electrically equivalent to the AG50 for Class G fuse applications at 480V with 100kA breaking capacity. However, the 0SLC050.T is a cartridge fuse that requires a holder, whereas the AG50 is an AMP-TRAP design. Compatibility depends on whether your existing fuse holder accepts cartridge-type fuses. Verify holder specifications before substitution.

Q: What are the key parameters that make these parts substitutable?

A: The critical parameters are: Class G fuse rating, 50A current rating, 480V AC voltage rating, and 100kA breaking capacity at rated voltage. Both parts meet these specifications and maintain ROHS3 compliance.

Q: Are there differences in response time or application suitability?

A: The 0SLC050.T is specified as medium blow response time and is approved for electrical and industrial applications. The AG50 is specified as AMP-TRAP technology. Both are suitable for industrial electrical protection circuits operating at 480V.

Q: What certifications does each part carry?

A: The AG50 carries ROHS3 compliance. The 0SLC050.T carries CE, CSA, QPL, and UL certifications in addition to ROHS3 compliance, providing broader regulatory acceptance across different markets and standards.

Q: Does packaging affect the substitution decision?

A: Yes. The AG50 is supplied in box packaging, while the 0SLC050.T is supplied in bulk and requires a separate fuse holder. Ensure your application has the appropriate holder for the cartridge fuse format before selecting the 0SLC050.T.
