MOC3063TM Optoisolator Equivalent & Substitute Parts

Part Overview

The MOC3063TM is a 4.17 kV optoisolator with triac output manufactured by onsemi in a 6-DIP through-hole package. This component features a zero-crossing circuit, single channel configuration, and is designed for high-voltage isolation applications. The MOC3063TM is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain compatibility across isolation voltage, output type, package form factor, and electrical operating parameters.

Substitute Part Grouping Explanation

Substitute parts for the MOC3063TM are classified into two categories based on electrical and mechanical compatibility:

Direct Substitute (Packaging Variant):

• MOC3063TVM: Identical electrical specifications to MOC3063TM with active product status and tube packaging. Maintains 4170 Vrms isolation voltage, 600 V/µs static dV/dt, 5 mA LED trigger current, and 6-DIP package form factor.

Similar Substitutes (Enhanced Specifications):

• EL3061M, EL3062M, EL3063M (Everlight Electronics): 5000 Vrms isolation voltage, 1 kV/µs static dV/dt, 6-DIP package. Differ in LED trigger current (15 mA, 10 mA, 5 mA respectively) and hold current (280 µA typical).
• Q3062, Q3063 (QT Brightek): 5000 Vrms isolation voltage, 1 kV/µs static dV/dt, 6-DIP package with reduced body width (0.300", 7.62 mm). LED trigger currents of 10 mA and 5 mA respectively.
• VO3063-X006 (Vishay): 5300 Vrms isolation voltage, 1.5 kV/µs static dV/dt, 6-DIP package (0.400", 10.16 mm). 5 mA LED trigger current with 200 µA typical hold current.

Substitution eligibility is determined by: matching output type (triac), zero-crossing circuit presence, single-channel configuration, 600 V off-state voltage, 60 mA maximum forward current, and compatible 6-DIP package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MOC3063TVM is the primary substitute for MOC3063TM. Both components share identical electrical specifications including 4170 Vrms isolation voltage, 600 V/µs static dV/dt, and 5 mA LED trigger current. MOC3063TVM maintains active product status and ROHS3 compliance, making it suitable for new designs requiring the original performance envelope.

For Enhanced Isolation Voltage Applications: EL3063M, Q3063, and VO3063-X006 provide higher isolation voltages (5000 Vrms to 5300 Vrms) with improved static dV/dt ratings (1 kV/µs to 1.5 kV/µs). These parts are appropriate when circuit design permits higher isolation specifications. All three maintain 5 mA LED trigger current matching the MOC3063TM. EL3063M and VO3063-X006 retain the 0.400" (10.16 mm) package width; Q3063 uses a narrower 0.300" (7.62 mm) body.

For Cost-Optimized Designs with Relaxed Isolation Requirements: EL3061M and Q3062 offer 5000 Vrms isolation with higher LED trigger currents (15 mA and 10 mA respectively). These parts are suitable when circuit design accommodates increased trigger current and higher isolation voltage is acceptable.

Compliance Considerations: All active substitute parts carry ROHS3 compliance. Approval agencies vary: onsemi parts carry UL approval; Everlight parts carry CSA, DEMKO, FIMKO, NEMKO, SEMKO, and UL approvals; QT Brightek parts carry UR and VDE approvals; Vishay carries cUR and UR approvals. Select based on regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can MOC3063TVM directly replace MOC3063TM without circuit modification? A: Yes. MOC3063TVM maintains identical electrical specifications including isolation voltage (4170 Vrms), static dV/dt (600 V/µs), LED trigger current (5 mA), and package form factor (6-DIP, 0.400" width). Both components feature zero-crossing circuits and triac output configuration.

Q: What is the primary difference between MOC3063TM and the Everlight EL3063M substitute? A: EL3063M provides higher isolation voltage (5000 Vrms vs. 4170 Vrms) and improved static dV/dt (1 kV/µs vs. 600 V/µs). LED trigger current remains identical at 5 mA. Hold current differs (280 µA typical vs. 500 µA typical). Both use identical 6-DIP package dimensions (0.400", 10.16 mm).

Q: Are Q3062 and Q3063 pin-compatible with MOC3063TM? A: Q3062 and Q3063 use 6-DIP package configuration with reduced body width (0.300", 7.62 mm vs. 0.400", 10.16 mm). Pin spacing remains compatible for through-hole mounting. PCB layout may require adjustment due to narrower package body. Both provide 5000 Vrms isolation and 1 kV/µs static dV/dt.

Q: Which substitute part offers the highest isolation voltage? A: VO3063-X006 provides the highest isolation voltage at 5300 Vrms with the fastest static dV/dt rating of 1.5 kV/µs. It maintains 5 mA LED trigger current and standard 6-DIP package dimensions (0.400", 10.16 mm), making it suitable for high-voltage isolation applications.

Q: What is the operating temperature range difference between MOC3063TM and substitute parts? A: MOC3063TM operates from -40°C to 85°C. All active substitute parts (MOC3063TVM, EL3061M, EL3062M, EL3063M, Q3062, Q3063, VO3063-X006) operate from -55°C to 100°C, providing extended temperature range capability.

Q: Do all substitute parts carry the same regulatory approvals as MOC3063TM? A: No. MOC3063TM carries UL approval. MOC3063TVM carries IEC/EN/DIN and UL approvals. Everlight parts carry CSA, DEMKO, FIMKO, NEMKO, SEMKO, and UL approvals. QT Brightek parts carry UR and VDE approvals. Vishay carries cUR and UR approvals. Select based on application certification requirements.

Q: Can EL3061M or EL3062M be used as substitutes despite higher LED trigger current? A: EL3061M (15 mA) and EL3062M (10 mA) have higher LED trigger currents than MOC3063TM (5 mA). Circuit design must accommodate increased input current requirements. Both provide 5000 Vrms isolation and 1 kV/µs static dV/dt with identical 6-DIP package dimensions.
