Substitute Part Grouping Explanation

The MHP-TAM6-9-82 qualifies as a direct substitute for the MHP-TA6-9-82 based on the following critical parameters:

• Rated Functioning Temperature: Both parts operate at 82°C (180°F)
• Reset Temperature: Both parts reset at 40°C (104°F)
• Voltage Rating - DC: Both rated at 9 V
• Current Rating: Both rated at 12 A
• Approval Agency: MHP-TAM6-9-82 carries cUL and UL certifications, meeting or exceeding the UL requirement of the original part
• RoHS Status: Both are ROHS3 Compliant
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• Manufacturer: Both manufactured by Littelfuse Inc.

The primary distinction is product status: MHP-TA6-9-82 is obsolete, while MHP-TAM6-9-82 is active. The MHP-TAM6-9-82 represents the active equivalent within the Littelfuse thermal cutoff product line.
