Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TRM10 are qualified based on the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Fuse Type: Cartridge (exact match required)
• Package / Case: 5AG, 10mm x 38mm Midget form factor (exact match required)
• Response Time: Slow Blow (functional equivalence)
• Product Status: Active (current availability)
• RoHS Compliance: ROHS3 Compliant (regulatory equivalence)

The identified substitutes meet all electrical and mechanical parameters necessary for direct replacement in applications requiring motor protection and transformer protection circuits.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the electrical and mechanical requirements for direct replacement of the TRM10:

The 0FLM010.T (Littelfuse Inc., Series FLM) provides an equivalent 10A 250VAC cartridge fuse with additional 125VDC rating capability and CSA, PSE, QPL, and UL approvals. Breaking capacity is specified at 10kA.

The FNM-10 (Eaton - Bussmann Electrical Division, Series FNM) provides an equivalent 10A 250VAC cartridge fuse with CE, CSA, and UL approvals. Breaking capacity is specified at 200A.

Both parts maintain ROHS3 compliance and Active product status, ensuring continued availability and regulatory alignment with the original TRM10 specification.

Frequently Asked Questions (FAQ)

Q: Can the 0FLM010.T and FNM-10 be used interchangeably with the TRM10?

A: Yes. Both substitute parts match the critical electrical parameters (10A, 250VAC) and mechanical form factor (5AG midget cartridge, 10mm x 38mm). All three parts are Active status and ROHS3 compliant.

Q: What is the significance of the 125VDC rating on the 0FLM010.T?

A: The 0FLM010.T includes a 125VDC rating in addition to the 250VAC rating. This provides expanded application flexibility for circuits operating in DC environments, though the TRM10 specification does not require DC operation.

Q: Are there differences in breaking capacity between the substitutes?

A: Yes. The 0FLM010.T specifies 10kA breaking capacity at rated voltage, while the FNM-10 specifies 200A breaking capacity. Both values are provided by the manufacturers and should be evaluated against the specific circuit requirements.

Q: Do all three parts require a fuse holder?

A: Yes. The TRM10, 0FLM010.T, and FNM-10 are all cartridge fuses that require a compatible holder for installation.

Q: What certifications apply to each part?

A: TRM10 certifications are not specified in available data. The 0FLM010.T carries CSA, PSE, QPL, and UL approvals. The FNM-10 carries CE, CSA, and UL approvals. Selection should align with regional regulatory requirements.
