Substitute Part Grouping Explanation

Substitution eligibility for the MOC3012M_F132 is determined by the following critical parameters:

• Output Type: Triac output configuration
• Voltage - Isolation: Minimum 4170Vrms isolation rating
• Package / Case: 6-DIP through-hole form factor
• Number of Channels: Single channel
• Current - LED Trigger (Ift): Maximum 5mA
• Operating Temperature Range: -40°C ~ 85°C or compatible range

The MOC3012M from Fairchild Semiconductor qualifies as a functional equivalent based on matching base product number (MOC301), triac output topology, and through-hole packaging. Both parts share the same ECCN and HTSUS classifications, confirming regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The MOC3012M from Fairchild Semiconductor is the identified equivalent for the obsolete MOC3012M_F132. Selection should be based on the following factors:

• Product Status: The Fairchild MOC3012M maintains active product status, ensuring continued availability and manufacturing support compared to the obsolete onsemi variant.
• Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, confirming equivalent export control and tariff treatment.
• Functional Alignment: Shared base product number (MOC301) and triac output topology establish functional equivalence for high-voltage isolation applications.
• Inventory Availability: The Fairchild variant shows significantly higher inventory levels (207,600 pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MOC3012M from Fairchild Semiconductor directly replace the onsemi MOC3012M_F132?

A: Yes. Both parts share the MOC301 base product number, identical triac output topology, and matching electrical isolation specifications. The 6-DIP through-hole package is identical, allowing direct board-level substitution.

Q: What is the isolation voltage rating difference between these parts?

A: The onsemi MOC3012M_F132 specifies 4170Vrms isolation. The Fairchild MOC3012M is rated for 5300V isolation, providing higher isolation margin. This represents an improvement over the original specification.

Q: Are there packaging differences between these optoisolators?

A: Both parts use 6-DIP through-hole packaging. The onsemi variant specifies 0.300" (7.62mm) pitch. No package incompatibility exists for PCB integration.

Q: Why is the onsemi MOC3012M_F132 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific variant. The Fairchild MOC3012M remains in active production, providing a supported alternative for equivalent functionality.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts carry UL approval and identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, confirming equivalent regulatory treatment for export and tariff purposes.
