K3010P Optoisolator Triac Output Equivalent & Substitute Parts

Part Overview

The K3010P is a 5.3kVrms optoisolator with triac output manufactured by Vishay Semiconductor Opto Division in 6-DIP through-hole packaging. This component provides galvanic isolation for AC switching applications with a single triac output channel. The K3010P is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across isolation voltage, output type, package configuration, and operating temperature range to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the K3010P is based on the following critical parameters:

Primary Compatibility Criteria:

• Output Type: Triac (mandatory)
• Package / Case: 6-DIP (0.300", 7.62mm) (mandatory)
• Mounting Type: Through Hole (mandatory)
• Voltage - Isolation: 5300Vrms or higher (minimum requirement)
• Voltage - Off State: 250 V (standard across all candidates)
• Number of Channels: 1 (mandatory)
• Operating Temperature Range: Must encompass or match -55°C ~ 100°C

Secondary Compatibility Criteria:

• Current - On State (It (RMS)): 100 mA or higher
• Current - LED Trigger (Ift): 15mA or lower
• Current - Hold (Ih): 100µA or higher
• Voltage - Forward (Vf): 1.15V to 1.25V typical range
• Current - DC Forward (If): 50mA or higher

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

Category A - Full Isolation Voltage Match (5300Vrms): MOC3010X, MOC3011X, MOC3012X (Isocom Components 2004 LTD) provide identical 5300Vrms isolation voltage with active product status and full compliance certifications.

Category B - Reduced Isolation Voltage (4170Vrms to 5000Vrms): EL3010-V, EL3011-V, EL3012-V (Everlight Electronics Co Ltd) and MOC3010VM, MOC3012VM (Fairchild Semiconductor) provide reduced isolation voltage ratings. MOC3009X (Isocom Components 2004 LTD) provides significantly lower isolation voltage (7.5Vpk) and is not suitable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Full Isolation Voltage Match):

MOC3010X, MOC3011X, and MOC3012X from Isocom Components 2004 LTD are the primary recommended substitutes. These parts maintain the full 5300Vrms isolation voltage specification of the K3010P, ensuring equivalent performance in high-voltage isolation applications. All three variants are active products with ROHS3 compliance and UR/VDE certifications. Selection among these three is determined by LED trigger current requirements: MOC3010X (15mA), MOC3011X (10mA), or MOC3012X (5mA). The lower trigger current variants reduce input circuit power consumption.

Secondary Substitutes (Reduced Isolation Voltage):

EL3010-V, EL3011-V, and EL3012-V from Everlight Electronics Co Ltd provide 5000Vrms isolation voltage, representing a 300Vrms reduction from the K3010P specification. These parts are suitable for applications where the reduced isolation margin is acceptable. Everlight parts offer extended temperature range matching the K3010P (-55°C ~ 100°C) and comprehensive certifications (CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, VDE). Selection among Everlight variants follows the same LED trigger current logic: EL3010-V (15mA), EL3011-V (10mA), or EL3012-V (5mA).

MOC3010VM and MOC3012VM from Fairchild Semiconductor provide 4170Vrms isolation voltage with reduced operating temperature range (-40°C ~ 85°C). These parts are suitable only for applications with relaxed isolation voltage and temperature requirements.

Not Recommended:

MOC3009X is not suitable as a direct substitute due to significantly lower isolation voltage (7.5Vpk) and higher LED trigger current (30mA), making it incompatible with the K3010P's high-voltage isolation specification.

Frequently Asked Questions (FAQ)

Q: Can MOC3010X, MOC3011X, and MOC3012X be used interchangeably with K3010P?

A: Yes, these three Isocom parts are direct substitutes with identical 5300Vrms isolation voltage and 6-DIP package. The difference between them is LED trigger current: MOC3010X requires 15mA, MOC3011X requires 10mA, and MOC3012X requires 5mA. Selection depends on your input circuit's ability to supply the required trigger current.

Q: What is the difference between the Isocom and Everlight substitute options?

A: Isocom parts (MOC3010X, MOC3011X, MOC3012X) maintain the full 5300Vrms isolation voltage. Everlight parts (EL3010-V, EL3011-V, EL3012-V) provide 5000Vrms isolation voltage. Both manufacturers offer active products with ROHS3 compliance. Everlight parts match the K3010P's extended temperature range (-55°C ~ 100°C), while Isocom parts operate from -40°C ~ 100°C.

Q: Are the Fairchild MOC3010VM and MOC3012VM suitable replacements?

A: MOC3010VM and MOC3012VM can be used only in applications where the reduced isolation voltage (4170Vrms) and narrower operating temperature range (-40°C ~ 85°C) are acceptable. These parts are not recommended for designs requiring the full 5300Vrms isolation specification or extended low-temperature operation.

Q: Why is MOC3009X not recommended as a substitute?

A: MOC3009X has isolation voltage of only 7.5Vpk, which is substantially lower than the K3010P's 5300Vrms specification. Additionally, MOC3009X requires 30mA LED trigger current compared to K3010P's 15mA maximum. This part is not functionally equivalent for high-voltage isolation applications.

Q: What certifications should I verify for my application?

A: All recommended substitutes carry relevant safety certifications. Isocom parts hold UR and VDE approvals. Everlight parts hold CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, and VDE approvals. Fairchild parts hold IEC/EN/DIN and UL approvals. Verify that the selected substitute's certification set meets your application's regulatory requirements.

Q: Can I use a substitute with lower LED trigger current in place of K3010P?

A: Yes. MOC3011X (10mA) and MOC3012X (5mA) have lower LED trigger current specifications than K3010P (15mA). Lower trigger current reduces input circuit power consumption and is compatible with K3010P designs. However, ensure your input circuit can reliably drive the lower trigger current threshold.

Q: What is the impact of different forward voltage (Vf) specifications?

A: K3010P has Vf of 1.25V typical. Substitute parts range from 1.15V to 1.2V typical. These small variations (0.05V to 0.10V) have minimal impact on input circuit design. Input current limiting resistors should be recalculated based on the selected substitute's Vf specification to maintain proper LED drive current.

Q: Are all substitutes ROHS3 compliant?

A: Isocom and Everlight substitutes are ROHS3 compliant. Fairchild parts (MOC3010VM, MOC3012VM) do not specify RoHS status in the provided data. Verify RoHS compliance with Fairchild if your application requires it.
