MOC3023TM Equivalent & Substitute Parts

Part Overview

The MOC3023TM is a 6-DIP optoisolator with triac output manufactured by onsemi, designed for high-voltage isolation applications. It features 4170Vrms isolation voltage, single-channel triac output, and operates across -40°C to 85°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Alternative models maintain core functionality while offering different packaging options, compliance certifications, and product status classifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for MOC3023TM is determined by the following critical parameters: output type (triac), number of channels (1), voltage isolation rating, off-state voltage (400V), LED trigger current, hold current, forward voltage, DC forward current, operating temperature range, package type (6-DIP), and mounting method (through hole).

Substitute parts are grouped into two categories:

Direct Equivalent (Packaging Variant): MOC3023TVM maintains identical electrical specifications and isolation voltage (4170Vrms) with the same base product number (MOC302). The primary difference is packaging format (tube vs. standard) and active product status.

Functional Alternatives (Parameter Variations): MOC3023M, IS3020, IS3021, IS3022, MOC3020G, MOC3021G, MOC3022G, and MOC3023G provide triac output optoisolation in 6-DIP packages with through-hole mounting. These alternatives differ in isolation voltage ratings, LED trigger current specifications, package dimensions, and compliance certifications. Selection depends on specific circuit requirements for isolation voltage and trigger current thresholds.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MOC3023TVM is the primary substitute for MOC3023TM. Both parts share identical electrical specifications (4170Vrms isolation, 5mA LED trigger current, 60mA DC forward current) and the same base product number (MOC302). MOC3023TVM is active in production with ROHS3 compliance and expanded approval certifications (IEC/EN/DIN, UL), making it suitable for new designs and production continuity.

For Functional Alternatives with Higher Isolation Voltage: MOC3023M (onsemi) maintains the same electrical specifications as MOC3023TM with active product status and ROHS3 compliance. Package dimension differs (0.300" vs. 0.400" DIP height), requiring PCB layout verification. IS3020, IS3021, and IS3022 (Isocom) provide 5300Vrms isolation with varying LED trigger currents (30mA, 15mA, 10mA respectively). These parts operate to 100°C and are ROHS3 compliant but lack specified approval agencies.

For Functional Alternatives with Lower Isolation Voltage: MOC3020G, MOC3021G, MOC3022G, and MOC3023G (Isocom) feature 7.5Vpk isolation voltage with LED trigger currents of 30mA, 15mA, 10mA, and 5mA respectively. These parts maintain 0.400" DIP package compatibility with MOC3023TM, operate to 100°C, include UL and VDE approvals, and are ROHS3 compliant. Selection among these variants depends on specific LED trigger current requirements.

Frequently Asked Questions (FAQ)

Q: Can MOC3023TVM directly replace MOC3023TM in existing designs? A: Yes. MOC3023TVM provides identical electrical specifications and isolation voltage (4170Vrms) with the same 6-DIP (0.400", 10.16mm) package. The primary difference is active product status and expanded compliance certifications. No circuit modifications are required.

Q: What is the key difference between MOC3023M and MOC3023TM? A: MOC3023M shares identical electrical specifications but uses a 6-DIP (0.300", 7.62mm) package versus the 0.400" package of MOC3023TM. PCB footprint and board layout must be verified for compatibility. MOC3023M is active in production with ROHS3 compliance.

Q: When should I use IS3020, IS3021, or IS3022 instead of MOC3023TM? A: These Isocom parts provide higher isolation voltage (5300Vrms vs. 4170Vrms) and extended operating temperature (-40°C to 100°C vs. -40°C to 85°C). Select based on circuit isolation requirements. LED trigger current varies: IS3020 (30mA), IS3021 (15mA), IS3022 (10mA). Package dimensions differ (0.300" DIP height).

Q: What are the differences between MOC3020G, MOC3021G, MOC3022G, and MOC3023G? A: All four parts are Isocom variants with 7.5Vpk isolation voltage, 0.400" DIP package, UL/VDE approvals, and 100°C operating temperature. The primary distinction is LED trigger current: MOC3020G (30mA), MOC3021G (15mA), MOC3022G (10mA), MOC3023G (5mA). Select based on circuit drive requirements.

Q: Are all substitute parts ROHS3 compliant? A: MOC3023TVM, MOC3023M, IS3020, IS3021, IS3022, MOC3020G, MOC3021G, MOC3022G, and MOC3023G are all ROHS3 compliant. MOC3023TM (obsolete) does not specify RoHS status.

Q: Which substitute offers the best compliance certifications? A: MOC3023TVM includes IEC/EN/DIN and UL approvals. MOC3020G, MOC3021G, MOC3022G, and MOC3023G include UL and VDE approvals. MOC3023M and IS series parts include UL approval only or no specified approval agencies.

Q: Can I use parts with different LED trigger currents interchangeably? A: No. LED trigger current (Ift) determines the input drive requirements. MOC3023TM and MOC3023TVM require 5mA maximum. IS3022 and MOC3022G also require 5mA. Parts with higher trigger currents (10mA, 15mA, 30mA) require proportionally higher input drive capability and are not interchangeable without circuit modification.

Q: What is the significance of the 0.300" vs. 0.400" DIP package height? A: Package height affects PCB footprint and board layout. MOC3023TM uses 0.400" (10.16mm) height. MOC3023M, IS3020, IS3021, and IS3022 use 0.300" (7.62mm) height. Verify PCB design accommodates the selected package before substitution. MOC3023TVM, MOC3020G, MOC3021G, MOC3022G, and MOC3023G maintain 0.400" compatibility with MOC3023TM.
