Key Parameters

Substitute Part Grouping Explanation

Substitution of the MHP-TAC6-12-72 is determined by strict equivalence across the following critical parameters:

• Functioning Temperature: 72°C (162°F) — must match exactly
• Reset Temperature: 40°C (104°F) — must match exactly
• Current Rating: 25 A — must match exactly
• Voltage Rating (DC): 12 V — must match exactly
• Configuration: SPST-NC — must match exactly
• Package Type: Nonstandard Strap — must match exactly
• Series Compatibility: MHP-TAC series — preferred for direct substitution

The substitute part MHP-TAC6-12-72N meets all these criteria and is classified as the manufacturer-recommended equivalent. Both parts share identical electrical and mechanical specifications, differing only in product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations
