MHP-TA6-9-85 Equivalent & Substitute Parts

Part Overview

The MHP-TA6-9-85 is a thermal cutoff (TCO) breaker manufactured by Littelfuse Inc., designed for AC/DC applications with a 12 A current rating and 85°C (185°F) functioning temperature. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain supply chain continuity and ensure design compatibility in applications requiring thermal protection at this specification level.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MHP-TA6-9-85 is based on strict equivalence of the following critical parameters:

• Rated Functioning Temperature: 85°C (185°F)
• Reset Temperature: 40°C (104°F)
• Voltage Rating - DC: 9 V
• Current Rating: 12 A
• Type: Breaker (Thermal Cutoff)
• Package / Case: Nonstandard
• Approval Agency: UL certification

The MHP-TAM6-9-85 meets all these criteria and is identified as a direct substitute. Both parts share identical electrical specifications, thermal characteristics, and regulatory approvals, with the primary distinction being product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The MHP-TAM6-9-85 is the direct equivalent for the obsolete MHP-TA6-9-85. Selection of the MHP-TAM6-9-85 is supported by:

• Identical electrical and thermal specifications across all critical parameters
• Active product status ensuring ongoing availability and supply chain support
• Equivalent UL certification with additional cUL approval, providing expanded regulatory coverage
• Matching RoHS3 compliance and MSL rating
• Nonstandard package configuration maintained across both parts

The transition from MHP-TA6-9-85 to MHP-TAM6-9-85 presents no functional or compliance barriers for thermal protection applications requiring 85°C cutoff operation at 12 A DC 9 V.

Frequently Asked Questions (FAQ)

Q: Can MHP-TAM6-9-85 be used as a direct replacement for MHP-TA6-9-85?

A: Yes. Both parts share identical electrical ratings (12 A, 9 V DC), thermal characteristics (85°C functioning, 40°C reset), and regulatory approvals. The MHP-TAM6-9-85 is the active equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (MHP-TA6-9-85 is obsolete; MHP-TAM6-9-85 is active) and packaging format (bag vs. nonstandard designation). All electrical and thermal specifications are identical.

Q: Are there any compliance differences?

A: The MHP-TAM6-9-85 carries both cUL and UL approvals, compared to UL only for the MHP-TA6-9-85. Both maintain ROHS3 compliance and MSL 1 rating.

Q: What parameters must remain constant for substitution?

A: Functioning temperature (85°C), reset temperature (40°C), voltage rating (9 V DC), current rating (12 A), and package type (nonstandard) must all match for valid substitution in thermal cutoff applications.
