FODM214R2 Equivalent & Substitute Parts

Part Overview

The FODM214R2 is an optoisolator with phototransistor output manufactured by onsemi. It provides galvanic isolation of 3750Vrms in a single-channel configuration with transistor output topology. The device is designed for AC and DC input applications and is currently in active production status. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and support component availability across different procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FODM214R2 is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating of 3750Vrms
• Single-channel configuration
• Transistor output topology
• Current transfer ratio range of 20% to 400% @ 1mA
• Maximum output voltage of 80V
• Maximum output current of 50mA per channel
• Input compatibility with both AC and DC signals
• 4-SOIC surface mount package with 0.173" (4.40mm) width
• Operating temperature range of -55°C to 110°C

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The FODM214 (onsemi) and LTV-214 (Lite-On Inc.) satisfy these requirements and are suitable for direct replacement in applications requiring the FODM214R2.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FODM214R2, FODM214, and LTV-214—maintain active product status and full compliance with RoHS3 and REACH regulations. The FODM214R2 and FODM214 are both onsemi products with identical electrical specifications and packaging. The LTV-214 from Lite-On Inc. provides an alternative source with equivalent parametric performance and identical package geometry, differing only in fall time specification (4µs versus 3µs), which remains within acceptable tolerance for most applications requiring this isolation voltage and output current rating.

Selection between these parts should be based on supply availability, procurement lead times, and established vendor relationships, as all three meet the specified electrical and mechanical requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the FODM214 be used as a direct replacement for the FODM214R2?

A: Yes. Both parts are manufactured by onsemi and share identical electrical specifications, isolation voltage, output characteristics, and 4-SOIC package dimensions. The primary difference is packaging format (Tape & Reel designation on the FODM214R2). Both are suitable for direct substitution in circuit designs.

Q: Is the LTV-214 compatible with applications designed for the FODM214R2?

A: Yes. The LTV-214 meets all critical parametric requirements including 3750Vrms isolation, 1-channel transistor output, 50mA maximum output current, and 4-SOIC surface mount package. The fall time specification of 4µs (versus 3µs on the FODM214R2) represents a minor timing difference that does not affect functional compatibility in standard optoisolator applications.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 4-SOIC package with 0.173" (4.40mm) width and are compatible with identical PCB footprints and reflow soldering profiles.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. The FODM214R2, FODM214, and LTV-214 are all RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the primary reason to consider substitute parts?

A: Supply chain continuity and component availability. While the FODM214R2 is in active production, using qualified substitutes such as the FODM214 or LTV-214 provides design flexibility and reduces procurement risk by enabling sourcing from multiple manufacturers and inventory channels.
