Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FODM3062R2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage - Isolation: 3750Vrms (exact match required)
• Output Type: Triac (exact match required)
• Zero Crossing Circuit: Yes (exact match required)
• Number of Channels: 1 (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Criteria (allowable variation):

• Voltage - Off State: 600V minimum
• Static dV/dt: 100V/µs minimum
• Current - LED Trigger (Ift): 10mA maximum
• Current - On State (It (RMS)): 50mA minimum
• Operating Temperature: -30°C to 100°C minimum range
• Package / Case: 4-SMD or 6-SOIC formats

The three substitute parts listed below meet all primary criteria and operate within acceptable secondary parameter ranges for direct substitution in applications designed for the FODM3062R2.

Parameter Comparison

Engineering Selection Recommendations

FODM3063R2 (onsemi) is the primary substitute for the FODM3062R2. Both parts share identical isolation voltage, off-state voltage, dV/dt rating, on-state current, and operating temperature range. The FODM3063R2 is currently in active production status with cUL and UL approval. The primary difference is a reduced LED trigger current (5mA vs. 10mA), which represents improved input efficiency. This part is available in Cut Tape and Digi-Reel packaging formats.

TLP266J(T7-TPL,E (Toshiba) is a qualified substitute with identical isolation voltage, off-state voltage, on-state current, and operating temperature range. This part features a 6-SOIC package format instead of 4-SMD, requiring PCB layout modification. The TLP266J maintains cUL and UL approval and is in active production. The static dV/dt rating is 200V/µs, which is lower than the FODM3062R2 but remains suitable for standard AC switching applications.

S2S4A00F (SHARP/Socle Technology) meets all primary isolation and functional criteria with 3750Vrms isolation and triac output with zero-crossing detection. This part is in active production with CSA and UR approval. The on-state current maximum is 50mA (vs. 70mA), and the static dV/dt is 100V/µs. Applications requiring the full 70mA on-state current or 600V/µs dV/dt performance should verify compatibility before selection. This part is available in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can I use FODM3063R2 as a direct replacement for FODM3062R2?

A: Yes. The FODM3063R2 is functionally equivalent with identical isolation voltage (3750Vrms), off-state voltage (600V), on-state current (70mA), and operating temperature range (-40°C to 100°C). Both parts use 4-SMD Gull Wing packaging and maintain cUL and UL approval. The FODM3063R2 features a lower LED trigger current (5mA vs. 10mA), which improves input efficiency without affecting output performance.

Q: What is the key difference between the TLP266J and FODM3062R2?

A: The primary difference is the package format. The TLP266J uses a 6-SOIC package while the FODM3062R2 uses 4-SMD Gull Wing. Both maintain identical isolation voltage, off-state voltage, and on-state current ratings. The TLP266J has a lower static dV/dt rating (200V/µs vs. 600V/µs), which is acceptable for standard AC switching but may require verification in high dV/dt environments.

Q: Is the S2S4A00F suitable for all FODM3062R2 applications?

A: The S2S4A00F meets all primary functional criteria (3750Vrms isolation, triac output, zero-crossing detection). However, the on-state current maximum is 50mA compared to 70mA for the FODM3062R2, and the static dV/dt is 100V/µs versus 600V/µs. Applications operating at or near the 70mA current limit or in high dV/dt switching environments should verify compatibility before deployment.

Q: What packaging options are available for substitutes?

A: FODM3063R2 is available in Cut Tape and Digi-Reel formats. S2S4A00F is available in Tape & Reel. TLP266J is available in Cut Tape and Digi-Reel. All three maintain surface mount technology suitable for automated assembly.

Q: Are all substitute parts RoHS compliant?

A: FODM3063R2 and TLP266J are ROHS3 compliant. S2S4A00F is RoHS compliant. All three parts are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the moisture sensitivity level for these parts?

A: All four parts (FODM3062R2, FODM3063R2, S2S4A00F, and TLP266J) carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
