Key Parameters

Substitute Part Grouping Explanation

Substitution of the FODM3011R3 is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 3750Vrms (mandatory match)
• Output Type: Triac (mandatory match)
• Number of Channels: 1 (mandatory match)
• Package / Case: 4-SMD, Gull Wing (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Current - On State (It (RMS)) (Max): 70 mA (mandatory match)
• Current - Hold (Ih): 300µA (Typ) (mandatory match)
• Voltage - Forward (Vf) (Typ): 1.2V (mandatory match)
• Current - DC Forward (If) (Max): 60 mA (mandatory match)
• Operating Temperature: -40°C ~ 100°C (mandatory match)

The FODM3053R2V-NF098 meets all critical substitution criteria. Variations in Voltage - Off State, Static dV/dt, Current - LED Trigger (Ift), and approval certifications do not preclude substitution when the mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

The FODM3053R2V-NF098 is the direct substitute for the obsolete FODM3011R3. Both components share identical isolation voltage, output type, channel configuration, package format, and critical electrical parameters governing triac operation.

The FODM3053R2V-NF098 offers the advantage of active product status, ensuring continued availability and manufacturing support. The component carries ROHS3 compliance and is supplied in Tape & Reel packaging, supporting automated assembly processes.

Approval certifications differ between the two parts. The FODM3011R3 holds BSI, CSA, and UL certifications, while the FODM3053R2V-NF098 carries cUR, UR, and VDE certifications. Selection between these parts should be based on the specific regulatory requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the FODM3053R2V-NF098 directly replace the FODM3011R3 in existing designs?

A: Yes. Both components meet identical specifications for isolation voltage (3750Vrms), output type (triac), channel count (1), package format (4-SMD, Gull Wing), and all critical electrical parameters including on-state current, hold current, and forward voltage.

Q: What is the significance of the higher Voltage - Off State rating in the FODM3053R2V-NF098?

A: The FODM3053R2V-NF098 specifies 600V off-state voltage compared to 250V in the FODM3011R3. This represents an enhanced capability that does not restrict substitution; the higher rating provides additional margin in applications where off-state voltage stress occurs.

Q: How do the approval certifications differ between these parts?

A: The FODM3011R3 carries BSI, CSA, and UL certifications. The FODM3053R2V-NF098 carries cUR, UR, and VDE certifications. Applications requiring specific regional or industry certifications must verify that the substitute part meets applicable standards.

Q: What packaging options are available for the FODM3053R2V-NF098?

A: The FODM3053R2V-NF098 is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The FODM3011R3 packaging format is not specified in available data.

Q: Is the FODM3053R2V-NF098 RoHS compliant?

A: Yes. The FODM3053R2V-NF098 is ROHS3 compliant. RoHS status for the FODM3011R3 is not specified in available data.

Q: What is the difference in LED trigger current between these parts?

A: The FODM3011R3 specifies a maximum LED trigger current (Ift) of 10mA, while the FODM3053R2V-NF098 specifies 5mA. The lower trigger current in the substitute part indicates improved LED efficiency and does not restrict substitution.
