Key Parameters

Substitute Part Grouping Explanation

Substitution of the FODM3012R4 is based on strict equivalence across the following critical parameters:

• Isolation voltage rating: 3750Vrms minimum
• Output type: Triac configuration
• Number of channels: Single channel
• Package type: 4-SMD, Gull Wing surface mount
• LED trigger current: 5mA maximum
• On-state RMS current: 70mA maximum
• Hold current: 300µA typical
• Forward voltage: 1.2V typical
• DC forward current: 60mA maximum
• Operating temperature range: -40°C to 100°C

The FODM3053R2V-NF098 meets all these core electrical and mechanical requirements, making it a direct functional equivalent for the obsolete FODM3012R4.

Parameter Comparison

Engineering Selection Recommendations

The FODM3053R2V-NF098 is the recommended substitute for the obsolete FODM3012R4. Both components share identical isolation voltage, output configuration, channel count, and critical electrical parameters. The FODM3053R2V-NF098 offers enhanced performance characteristics: higher off-state voltage rating (600V versus 250V) and superior static dV/dt capability (1kV/µs versus 10V/µs typical), providing greater margin in high-speed switching applications.

The substitute part carries active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The FODM3053R2V-NF098 is supplied in Tape & Reel packaging, standard for production environments, compared to the bulk packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the FODM3053R2V-NF098 directly replace the FODM3012R4 in existing designs?

A: Yes. Both components share identical isolation voltage (3750Vrms), triac output configuration, single-channel architecture, and all critical electrical parameters including LED trigger current, on-state current, hold current, and forward voltage specifications. The 4-SMD Gull Wing package is identical, enabling direct PCB compatibility.

Q: What are the differences between these two parts?

A: The FODM3053R2V-NF098 provides enhanced electrical performance with higher off-state voltage (600V versus 250V) and faster dV/dt rating (1kV/µs versus 10V/µs typical). The substitute is actively manufactured and ROHS3 compliant, whereas the original is obsolete. Packaging format differs: the substitute uses Tape & Reel while the original was supplied in bulk.

Q: Are there any circuit design considerations when switching to the FODM3053R2V-NF098?

A: No design modifications are required. The enhanced electrical specifications of the substitute part provide additional performance margin without requiring circuit changes. All input and output electrical parameters remain within the original design envelope.

Q: What certifications apply to the substitute part?

A: The FODM3053R2V-NF098 carries cUR, UR, and VDE approvals, with ROHS3 compliance. The original FODM3012R4 held BSI, CSA, and UL certifications. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: Is the Tape & Reel packaging compatible with existing assembly processes?

A: Yes. Tape & Reel is the standard production packaging format for surface mount components and is compatible with automated pick-and-place assembly equipment. This packaging format is preferred for manufacturing environments compared to bulk packaging.
