Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAC12SN is determined by strict equivalence across the following critical parameters:

• Triac Type classification (Logic - Sensitive Gate)
• Voltage - Off State rating (800 V)
• Current - On State maximum (12 A)
• Voltage - Gate Trigger maximum (1.5 V)
• Current - Gate Trigger maximum (5 mA)
• Current - Hold maximum (10 mA)
• Current - Non Rep. Surge rating (90 A @ 60Hz)
• Operating Temperature range (-40°C ~ 110°C)
• Package / Case designation (TO-220-3)
• Mounting Type (Through Hole)

The MAC12SNG qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAC12SNG is the direct equivalent for MAC12SN applications. Both components share identical electrical and thermal specifications, with full mechanical compatibility in TO-220-3 through-hole mounting. The MAC12SNG carries Active product status, ensuring continued availability and manufacturing support. Both parts maintain equivalent RoHS and REACH compliance classifications. Selection of MAC12SNG eliminates obsolescence risk while preserving circuit performance and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can MAC12SNG replace MAC12SN in existing designs? A: Yes. The MAC12SNG provides electrical and mechanical equivalence across all specified parameters, including voltage ratings, current ratings, gate trigger characteristics, and thermal operating range. Through-hole TO-220-3 mounting is identical.

Q: What is the difference between TO-220 and TO-220AB packaging? A: Both designations refer to the same three-lead through-hole package form factor. The TO-220AB designation indicates the specific variant used by the supplier. Mechanical and electrical compatibility is maintained.

Q: Why is MAC12SN classified as obsolete? A: Obsolete status indicates the part is no longer in active production. MAC12SNG, with identical specifications and Active status, is the recommended alternative for new designs and ongoing procurement.

Q: Are there compliance differences between MAC12SN and MAC12SNG? A: Both parts share equivalent ECCN (EAR99) and HTSUS (8541.30.0080) classifications. RoHS and REACH compliance status is equivalent.

Q: What inventory considerations apply to these parts? A: MAC12SN inventory is limited (855 Pcs). MAC12SNG is available in higher quantity (1650 Pcs) with Active product status, providing superior long-term supply assurance.
