MOCD213R1M Equivalent & Substitute Parts

Part Overview

The MOCD213R1M is a 2-channel optoisolator with transistor output manufactured by onsemi, rated for 2500Vrms isolation voltage. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement.

The MOCD213R1M operates with 2 channels, 150mA output current per channel, and a maximum output voltage of 70V. Its 8-SOIC surface mount package and DC input type make it suitable for industrial isolation applications requiring moderate isolation ratings.

Substitute Part Grouping Explanation

Substitution for the MOCD213R1M is determined by the following critical parameters:

Parametric Equivalents maintain identical electrical specifications:

2 channels
2500Vrms isolation voltage
100% current transfer ratio @ 10mA
150mA output current per channel
70V maximum output voltage
8-SOIC package form factor
-40°C to 100°C operating temperature range

Similar Substitutes provide functional equivalence with relaxed parameters:

Higher isolation voltage (3000Vrms or 4000Vrms) provides enhanced isolation margin
Different current transfer ratio specifications accommodate broader application requirements
Reduced output current capability (50mA) suitable for lower-power isolation circuits
Extended or modified operating temperature ranges
Compatible 8-SOIC or 8-SO package footprints

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents):

MOCD213R2M and MOCD213R2VM are direct parametric equivalents to the MOCD213R1M. Both parts maintain identical electrical specifications and package form factor. MOCD213R2M and MOCD213R2VM are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. These parts are recommended as primary replacements for obsolete MOCD213R1M applications.

Alternative Substitutes (Higher Isolation Rating):

The Broadcom ACPL-227 series (ACPL-227-500E, ACPL-227-50BE, ACPL-227-50CE, ACPL-227-560E, ACPL-227-56BE, ACPL-227-56CE) provides 3000Vrms isolation, exceeding the MOCD213R1M specification. These parts are suitable for applications where enhanced isolation margin is beneficial. The ACPL-227 series exhibits reduced output current capability (50mA versus 150mA) and operates at lower input current levels (5mA versus 10mA). All ACPL-227 variants are active products with ROHS3 compliance.

Alternative Substitutes (Highest Isolation Rating):

The Vishay ILD205T and ILD206T provide 4000Vrms isolation with 8-SOIC packaging compatible with the MOCD213R1M footprint. These parts maintain 70V maximum output voltage and operate across -55°C to 100°C temperature range. Both are active products with ROHS3 compliance. The ILD205T and ILD206T exhibit lower current transfer ratios (40-125% @ 10mA) compared to the MOCD213R1M (100% @ 10mA).

Frequently Asked Questions (FAQ)

Q: Can MOCD213R2M directly replace MOCD213R1M in existing designs?

A: Yes. MOCD213R2M is a parametric equivalent with identical electrical specifications, channel count, isolation voltage, output current rating, and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the difference between MOCD213R2M and MOCD213R2VM?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is packaging format: MOCD213R2M is supplied in Cut Tape and Digi-Reel format, while MOCD213R2VM is also available in Cut Tape and Digi-Reel format. Electrical performance is identical.

Q: Can ACPL-227 series parts replace MOCD213R1M?

A: ACPL-227 series parts provide functional substitution with trade-offs. The 3000Vrms isolation exceeds MOCD213R1M requirements. However, output current is reduced to 50mA (versus 150mA), and input current operates at 5mA (versus 10mA). Applications requiring the full 150mA output current cannot use ACPL-227 substitutes without circuit redesign.

Q: Are there package compatibility concerns with Broadcom ACPL-227 parts?

A: ACPL-227 parts use 8-SOIC packaging with 4.40mm width, compared to MOCD213R1M at 3.90mm width. While both are 8-SOIC form factors, the slightly larger package width may require PCB layout verification for space-constrained designs.

Q: What isolation voltage should I select for new designs?

A: Selection depends on application requirements. MOCD213R2M maintains the original 2500Vrms specification. ACPL-227 series (3000Vrms) and ILD205T/ILD206T (4000Vrms) provide higher isolation margins for demanding industrial environments. Higher isolation ratings do not negatively impact lower-voltage applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MOCD213R2M, MOCD213R2VM, all ACPL-227 variants, ILD205T, and ILD206T are ROHS3 compliant. The obsolete MOCD213R1M does not carry RoHS certification.
