MOC8030SD Equivalent & Substitute Parts

Part Overview

The MOC8030SD is a 5300Vrms isolation optoisolator with Darlington output manufactured by onsemi in a 6-SMD surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MOC8030SD provides single-channel isolation suitable for applications requiring high voltage isolation with Darlington output configuration and 150mA output current capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MOC8030SD is determined by the following critical parameters: isolation voltage rating, number of channels, output type (Darlington), maximum output voltage, output current capability, package type (6-SMD, Gull Wing), and operating temperature range. Substitute parts must maintain compatibility across these electrical and mechanical specifications to ensure functional equivalence in the target application.

The identified substitute parts are grouped into two categories based on isolation voltage alignment:

Category 1: Full Isolation Voltage Match (5300Vrms)

• 4N32FSM (Isocom Components 2004 LTD)
• MOC8030SM (Isocom Components 2004 LTD)
• MOC8030SMT&R (Isocom Components 2004 LTD)

Category 2: Reduced Isolation Voltage (4170Vrms)

• MOC8050SR2M (onsemi)

Parameter Comparison

Engineering Selection Recommendations

MOC8050SR2M (onsemi): This part is manufactured by onsemi, the original manufacturer of the MOC8030SD, and maintains active product status. It provides the same 80V maximum output voltage and 150mA output current as the original part. The isolation voltage is reduced to 4170Vrms, which represents a 21% decrease from the MOC8030SD specification. This substitute is suitable only for applications where the lower isolation voltage meets design requirements. The MOC8050SR2M includes RoHS3 compliance and is available in Cut Tape and Digi-Reel packaging with higher inventory availability (12,400 units).

4N32FSM (Isocom Components 2004 LTD): This part maintains the full 5300Vrms isolation voltage specification of the MOC8030SD and is manufactured by an active supplier. However, the output current is limited to 80mA compared to the MOC8030SD's 150mA capability, representing a 47% reduction. The operating temperature range is narrower (-25°C ~ 100°C versus -55°C ~ 100°C). This substitute is applicable only when the reduced output current and narrower temperature range are compatible with the application. RoHS3 compliance is confirmed.

MOC8030SM (Isocom Components 2004 LTD): This part provides 5000Vrms isolation voltage (94% of the MOC8030SD specification) with active product status. Output current is limited to 80mA. The operating temperature range extends to 110°C maximum, providing broader high-temperature coverage than the original part. Current transfer ratio matches the MOC8030SD at 300% @ 10mA. RoHS3 compliance is confirmed. This substitute is suitable when the slightly reduced isolation voltage and output current are acceptable.

MOC8030SMT&R (Isocom Components 2004 LTD): This part is electrically identical to MOC8030SM with 5000Vrms isolation voltage and 80mA output current. The primary difference is packaging format (Tape & Reel versus Tube). Operating temperature range extends to 110°C. RoHS3 compliance is confirmed. This substitute is suitable for high-volume procurement requiring reel packaging.

Frequently Asked Questions (FAQ)

Q: Can MOC8050SR2M be used as a direct replacement for MOC8030SD?

A: MOC8050SR2M is electrically compatible in terms of package, output voltage, and output current. However, the isolation voltage is reduced from 5300Vrms to 4170Vrms. Substitution is valid only if the application design does not require the higher isolation voltage specification of the original part.

Q: What is the primary limitation of 4N32FSM as a substitute?

A: The 4N32FSM has a maximum output current of 80mA compared to the MOC8030SD's 150mA. Applications requiring the full 150mA output current cannot use this substitute. Additionally, the operating temperature range is limited to -25°C ~ 100°C, which may not be suitable for applications requiring operation below -25°C.

Q: Are MOC8030SM and MOC8030SMT&R functionally equivalent?

A: Yes, MOC8030SM and MOC8030SMT&R are electrically identical. The difference is packaging format: MOC8030SM is supplied in Tube packaging, while MOC8030SMT&R is supplied in Tape & Reel format. Selection between these two depends on procurement and assembly requirements.

Q: Which substitute maintains the closest electrical match to MOC8030SD?

A: MOC8030SM and MOC8030SMT&R maintain the closest electrical match with 5000Vrms isolation voltage (94% of original specification) and matching current transfer ratio of 300% @ 10mA. The primary trade-off is reduced output current (80mA versus 150mA).

Q: What compliance certifications are available for substitute parts?

A: All substitute parts carry RoHS3 compliance and REACH Unaffected status, matching the environmental compliance profile of the MOC8030SD. All parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Q: Can I use MOC8050SR2M in applications requiring -55°C operation?

A: No. MOC8050SR2M has a minimum operating temperature of -40°C, which does not meet the -55°C requirement of the original MOC8030SD. For applications requiring -55°C operation, MOC8030SM, MOC8030SMT&R, or 4N32FSM are suitable alternatives.
