FODM3011 Optoisolator Equivalent & Substitute Parts

Part Overview

The FODM3011 is a 3.75kV isolation optoisolator with triac output, designed for single-channel applications requiring high-voltage isolation in surface mount packaging. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The FODM3011 operates across the industrial temperature range of -40°C to 100°C and is approved by BSI, CSA, and UL standards bodies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FODM3011 is determined by the following critical parameters:

• Isolation Voltage: Must maintain 3750Vrms minimum isolation rating
• Output Type: Must be triac output configuration
• Number of Channels: Must be single channel (1)
• Package Type: Must be 4-SMD, Gull Wing surface mount
• Operating Temperature Range: Must support -40°C to 100°C minimum
• Mounting Type: Must be surface mount compatible

The FODM3053R2V-NF098 meets all substitution criteria, maintaining identical isolation voltage, output type, channel count, package configuration, and operating temperature range. This part is manufactured by the same supplier (onsemi) and shares the same base product number (FODM30), confirming functional equivalence within the product family.

Engineering Selection Recommendations

The FODM3053R2V-NF098 is the direct substitute for the obsolete FODM3011. Both parts share identical core electrical specifications for isolation voltage, output type, channel configuration, and operating temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The FODM3053R2V-NF098 offers enhanced electrical performance characteristics, including higher off-state voltage (600V vs. 250V), superior static dV/dt rating (1kV/µs vs. 10V/µs), and lower LED trigger current requirement (5mA vs. 10mA). These improvements provide greater design margin and operational reliability without compromising functional compatibility.

Compliance certifications differ between the two parts: the FODM3011 carries BSI, CSA, and UL approvals, while the FODM3053R2V-NF098 carries cUR, UR, and VDE approvals. The substitute part is RoHS3 compliant, whereas the original part does not specify RoHS status. Both parts maintain REACH unaffected status and identical moisture sensitivity levels (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the FODM3053R2V-NF098 directly replace the FODM3011 in existing designs?

A: Yes. Both parts maintain identical isolation voltage (3750Vrms), triac output configuration, single-channel design, 4-SMD gull wing package, and operating temperature range (-40°C to 100°C). The substitute part is functionally equivalent for circuit-level substitution.

Q: What are the key differences between these parts?

A: The FODM3053R2V-NF098 provides enhanced electrical performance with higher off-state voltage (600V vs. 250V), faster static dV/dt response (1kV/µs vs. 10V/µs), and lower LED trigger current (5mA vs. 10mA). The substitute part is in active production status, whereas the FODM3011 is obsolete.

Q: Are there packaging differences between the FODM3011 and FODM3053R2V-NF098?

A: Both parts use identical 4-SMD, gull wing surface mount packaging. The FODM3053R2V-NF098 is supplied in tape and reel format, which is standard for active production parts.

Q: What compliance certifications apply to the substitute part?

A: The FODM3053R2V-NF098 carries cUR, UR, and VDE approvals and is RoHS3 compliant. Verify that these certifications meet your specific application and regional requirements.

Q: Why is the LED trigger current lower on the substitute part?

A: The FODM3053R2V-NF098 requires 5mA maximum LED trigger current compared to 10mA for the FODM3011. This represents improved input circuit efficiency and does not affect output performance or compatibility.
