Z0103MAG Equivalent & Substitute Parts

Part Overview

The Z0103MAG is a Logic - Sensitive Gate TRIAC rated for 600 V off-state voltage and 1 A on-state current, packaged in TO-92 through-hole configuration. Manufactured by onsemi, this component is classified as obsolete. Due to its obsolete status and limited inventory availability (876 pcs), identifying active equivalent parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Z0103MAG is determined by the following critical parameters:

• Triac Type: Logic - Sensitive Gate configuration must be maintained
• Voltage Rating: 600 V off-state voltage is the minimum requirement
• Current Rating: 1 A on-state current (RMS) maximum
• Gate Trigger Characteristics: Vgt (Max) 1.3 V and Igt (Max) 3 mA define gate sensitivity
• Hold Current: Ih (Max) specification ensures reliable latching behavior
• Package: TO-92-3 through-hole configuration for mechanical and thermal compatibility
• Operating Temperature: -40°C ~ 125°C junction temperature range

The Z0103MA 1AA2 manufactured by STMicroelectronics meets all substitution criteria with identical or superior electrical specifications and maintains the same through-hole package configuration.

Engineering Selection Recommendations

The Z0103MA 1AA2 is the direct substitute for the Z0103MAG. Selection is supported by the following factors:

• Product Status: The Z0103MA 1AA2 is active and in production, ensuring long-term availability and supply chain stability, whereas the Z0103MAG is obsolete.
• Electrical Equivalence: All critical electrical parameters match or exceed the original specification, including voltage rating, current rating, and gate trigger characteristics.
• Compliance: The Z0103MA 1AA2 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Package Compatibility: Both components use identical TO-92-3 through-hole packaging, enabling direct board-level substitution without layout modifications.
• Inventory Availability: The Z0103MA 1AA2 has significantly higher inventory availability (90,400 pcs), supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Z0103MA 1AA2 be used as a direct replacement for the Z0103MAG?

A: Yes. The Z0103MA 1AA2 meets all electrical and mechanical specifications required for direct substitution. Both components share identical Triac type, voltage rating, current rating, gate trigger characteristics, and TO-92-3 package configuration.

Q: What is the difference in hold current between these parts?

A: The Z0103MAG specifies a maximum hold current (Ih) of 10 mA, while the Z0103MA 1AA2 specifies 7 mA maximum. The lower hold current of the substitute part is compatible with applications designed for the original part, as it represents a tighter specification.

Q: Are there any package differences between the Z0103MAG and Z0103MA 1AA2?

A: Both components use TO-92-3 through-hole packaging. The Z0103MA 1AA2 is designated as TO-226AA variant, which is mechanically and electrically equivalent to the TO-226-3 package used by the Z0103MAG. No board layout or footprint modifications are required.

Q: What compliance certifications apply to the Z0103MA 1AA2?

A: The Z0103MA 1AA2 is RoHS3 compliant and REACH unaffected. Both components share identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: Why is the Z0103MAG classified as obsolete?

A: The Z0103MAG is an older onsemi product that has been superseded by newer alternatives. The Z0103MA 1AA2 from STMicroelectronics provides equivalent functionality with active production status and improved supply chain availability.
