INN2214K-TL Equivalent & Substitute Parts

Part Overview

The INN2214K-TL is an offline switching converter IC manufactured by Power Integrations, part of the InnoSwitch™-CP series. This device implements a flyback topology with secondary-side synchronous rectification (SR), operating at 100kHz switching frequency with a 20W power rating. The IC is designed for isolated power supply applications requiring offline operation with integrated primary-side switching functionality and comprehensive fault protection.

The INN2214K-TL maintains Active product status with full RoHS compliance and REACH unaffected designation. Substitute parts are identified based on matching electrical characteristics, package compatibility, and operational parameters that define functional equivalence within this power management category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INN2214K-TL is determined by strict parameter matching across the following critical criteria:

Mandatory Matching Parameters:

• Manufacturer: Power Integrations
• Series: InnoSwitch™-CP
• Topology: Flyback, Secondary Side SR
• Voltage - Breakdown: 650V
• Frequency - Switching: 100kHz
• Output Isolation: Isolated
• Package / Case: 16-PowerSOIC (0.350", 8.89mm Width), 15 Leads
• Supplier Device Package: eSOP-R16B
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Fault Protection: Current Limiting, Over Temperature, Over Voltage
• RoHS Status: RoHS Compliant
• MSL Rating: 3 (168 Hours)

Allowable Variation Parameter:

• Power (Watts): Substitutes may have equal or higher power rating while maintaining all other specifications

The INN2215K-TL qualifies as a parametric equivalent substitute based on matching all mandatory parameters while providing an increased power rating of 25W, which is compatible with applications designed for the 20W INN2214K-TL.

Parameter Comparison

Engineering Selection Recommendations

INN2215K-TL as Primary Substitute:

The INN2215K-TL is a direct parametric equivalent to the INN2214K-TL with identical electrical and mechanical specifications except for power rating. Both devices maintain Active product status, full RoHS compliance, and REACH unaffected designation. The INN2215K-TL's 25W power rating provides additional headroom compared to the INN2214K-TL's 20W rating while preserving all operational characteristics, topology implementation, and protection features.

Both parts share identical package geometry (16-PowerSOIC eSOP-R16B), mounting methodology (Surface Mount), and thermal operating range (-40°C to 150°C junction temperature). Moisture sensitivity level and compliance certifications are equivalent across both devices.

Selection between these parts depends on application power requirements. The INN2215K-TL is suitable for applications requiring the 20W capability of the INN2214K-TL and for designs that benefit from the higher 25W rating within the same form factor and electrical interface.

Frequently Asked Questions (FAQ)

Q: Can the INN2215K-TL replace the INN2214K-TL in existing designs?

A: Yes. The INN2215K-TL matches all electrical and mechanical parameters of the INN2214K-TL. The higher power rating (25W vs 20W) is compatible with applications designed for the 20W device. Package geometry, pin configuration, and operating characteristics are identical.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both devices operate across the identical temperature range (-40°C to 150°C junction temperature) and share the same MSL rating (3, 168 Hours). Fault protection mechanisms are identical.

Q: Do these parts require different PCB layouts or design modifications?

A: No. Both parts use the 16-PowerSOIC (eSOP-R16B) package with identical pin assignments and mechanical dimensions (0.350", 8.89mm width). PCB layouts designed for the INN2214K-TL are directly compatible with the INN2215K-TL.

Q: What is the significance of the power rating difference?

A: The INN2215K-TL's 25W rating versus the INN2214K-TL's 20W rating reflects maximum continuous power handling capability. Applications operating at or below 20W can use either part. The INN2215K-TL provides additional design margin and is suitable for applications approaching the 20W limit.

Q: Are compliance certifications identical?

A: Yes. Both parts are RoHS Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What switching topology do these devices implement?

A: Both the INN2214K-TL and INN2215K-TL implement a flyback topology with secondary-side synchronous rectification (SR), operating at 100kHz switching frequency with 60% duty cycle and 650V breakdown voltage rating.
