MOCD213VM Equivalent & Substitute Parts

Part Overview

The MOCD213VM is a 2-channel optoisolator with transistor output manufactured by onsemi, rated for 2500Vrms isolation voltage. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The MOCD213VM operates with a 100% minimum current transfer ratio at 10mA input, 150mA maximum output current per channel, and supports operating temperatures from -40°C to 100°C in an 8-SOIC surface mount package.

Substitute Part Grouping Explanation

Substitution for the MOCD213VM is determined by the following critical parameters:

Isolation Voltage: Minimum 2500Vrms (higher ratings acceptable)
Package / Case: 8-SOIC form factor with compatible pinout
Mounting Type: Surface mount
Input Type: DC input
Vce Saturation: Maximum 400mV

Substitute parts are grouped into two categories based on isolation voltage rating:

Category A - Higher Isolation (3000Vrms): Broadcom ACPL-227 series variants offer increased isolation voltage with active product status and RoHS3 compliance. These parts feature reduced output current capability (50mA per channel vs. 150mA) but maintain compatible switching characteristics.

Category B - Higher Isolation (4000Vrms): Vishay ILD series parts provide the highest isolation rating with active product status and RoHS3 compliance. These parts also feature reduced output current capability and slower switching times compared to the MOCD213VM.

Engineering Selection Recommendations

Broadcom ACPL-227 Series (3000Vrms): These parts are active products with RoHS3 compliance and extended operating temperature range (-55°C to 110°C). The ACPL-227-50CE and ACPL-227-56CE variants provide current transfer ratios (200% and 200% minimum respectively) that exceed the MOCD213VM specification. However, output current per channel is limited to 50mA compared to 150mA on the original part. Package width differs (4.40mm vs. 3.90mm), requiring PCB layout verification. These parts are suitable for applications where higher isolation voltage and compliance certifications are required and output current demands do not exceed 50mA per channel.

Vishay ILD Series (4000Vrms): The ILD213T provides the closest current transfer ratio match (100% minimum @ 10mA) to the MOCD213VM and maintains the original 3.90mm package width. All ILD variants are active products with RoHS3 compliance. The ILD213T operates across -55°C to 100°C. Output current specifications are not provided for the ILD series. Switching times are slower (6µs turn-on, 5µs turn-off) compared to the MOCD213VM (3µs, 2.8µs). These parts are suitable for applications requiring maximum isolation voltage and compatible package dimensions.

Product Status Consideration: All substitute parts listed are active products, ensuring long-term availability and supply chain stability compared to the obsolete MOCD213VM.

Frequently Asked Questions (FAQ)

Q: Can ACPL-227 series parts directly replace MOCD213VM in existing designs?

A: ACPL-227 parts are functionally compatible as 2-channel transistor output optoisolators with higher isolation voltage (3000Vrms vs. 2500Vrms). However, the package width differs (4.40mm vs. 3.90mm), requiring PCB layout verification. Output current per channel is reduced to 50mA, which must be evaluated against circuit requirements. Pinout compatibility should be confirmed before substitution.

Q: What is the primary limitation when substituting with Broadcom ACPL-227 variants?

A: The maximum output current per channel is 50mA on all ACPL-227 variants, compared to 150mA on the MOCD213VM. Applications requiring higher output current must use alternative parts or circuit modifications.

Q: Why do ILD series parts have slower switching times?

A: The ILD series is specified with 6µs turn-on and 5µs turn-off times compared to 3µs and 2.8µs on the MOCD213VM. This is a characteristic of the Vishay ILD design and must be evaluated for timing-critical applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (ACPL-227 series and ILD series) are RoHS3 compliant. The MOCD213VM RoHS status is not specified.

Q: Which substitute part provides the best current transfer ratio match?

A: The ILD213T and ACPL-227-50CE/56CE variants provide the highest current transfer ratios. ILD213T specifies 100% minimum @ 10mA, matching the MOCD213VM. ACPL-227-50CE and ACPL-227-56CE specify 200% minimum @ 5mA, exceeding the original specification.

Q: Can package width differences affect PCB compatibility?

A: Yes. ACPL-227 parts use 4.40mm width packages while MOCD213VM and ILD series use 3.90mm width packages. PCB footprints must be verified for compatibility. ILD series parts maintain the original package width and may require fewer layout modifications.

Q: What is the temperature range difference between MOCD213VM and substitutes?

A: MOCD213VM operates -40°C to 100°C. ACPL-227 series extends to -55°C to 110°C. ILD series operates -55°C to 100°C. Applications requiring operation below -40°C must use ACPL-227 or ILD series.
