TNY264P Equivalent & Substitute Parts

Part Overview

The TNY264P is an offline switch flyback converter IC from Power Integrations' TinySwitch®-II series, designed for isolated power supply applications. This 8-DIP package device integrates a 700V internal switch with comprehensive fault protection including current limiting, open loop, over temperature, and short circuit protection. The TNY264P is classified as obsolete, making identification of functionally equivalent substitute parts essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution of the TNY264P is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Topology: Flyback converter architecture
• Output Isolation: Isolated configuration
• Voltage - Breakdown: 700V internal switch rating
• Frequency - Switching: 132kHz operating frequency
• Power Rating: 9 W output capability
• Duty Cycle: 65% maximum duty cycle
• Fault Protection: Current Limiting, Open Loop, Over Temperature, Short Circuit
• Control Features: EN (Enable) control
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Package / Case: 8-DIP (0.300", 7.62mm), 7 Leads
• Mounting Type: Through Hole

The TNY264PN is the direct manufacturer equivalent, sharing identical electrical specifications and package configuration. Additional substitute parts within the TinySwitch®-II series (TNY263PN, TNY265PN, TNY266PG, TNY267PN, TNY268PN) are available from the TNY264PN substitute list and maintain core topology and isolation characteristics, though specific parameter variations may exist within the series.

Parameter Comparison

Engineering Selection Recommendations

TNY264PN is the direct functional equivalent to TNY264P. Both devices share identical electrical specifications, switching frequency, power rating, fault protection architecture, and 8-DIP package configuration. The primary distinction is product status and regulatory compliance:

• TNY264P is classified as Obsolete with RoHS non-compliant status
• TNY264PN is classified as Not For New Designs with RoHS Compliant status

For new designs or production requiring RoHS compliance, TNY264PN is the appropriate selection. For legacy system maintenance or replacement of existing TNY264P installations, TNY264PN provides electrical and mechanical compatibility with improved regulatory standing.

The TNY264PN substitute list includes TNY263PN, TNY265PN, TNY266PG, TNY267PN, and TNY268PN, which are alternative TinySwitch®-II series devices. Selection among these alternatives requires detailed parameter comparison against specific application requirements beyond the scope of direct TNY264P substitution.

Frequently Asked Questions (FAQ)

Q: Can TNY264PN be used as a direct replacement for TNY264P?

A: Yes. TNY264PN is electrically and mechanically equivalent to TNY264P. Both devices feature identical 700V breakdown voltage, 132kHz switching frequency, 9W power rating, 65% duty cycle, and 8-DIP through-hole package configuration. Pin-for-pin compatibility is maintained.

Q: What is the difference between TNY264P and TNY264PN?

A: The devices are functionally identical. TNY264P is obsolete and RoHS non-compliant. TNY264PN is classified as Not For New Designs and is RoHS Compliant. TNY264PN is supplied in Tube packaging, while TNY264P packaging is not specified.

Q: Are the other TinySwitch®-II series parts (TNY263PN, TNY265PN, TNY266PG, TNY267PN, TNY268PN) direct replacements?

A: These are alternative devices within the same TinySwitch®-II series and share the same topology and isolation characteristics. They are not direct pin-for-pin replacements. Substitution requires verification of specific electrical parameters against application requirements.

Q: What is the 8-DIP package specification?

A: The 8-DIP (0.300", 7.62mm) package is a through-hole dual inline package with 8 pins and 7 leads. Pin spacing is 0.300 inches (7.62mm). This package is standard for both TNY264P and TNY264PN.

Q: Is TNY264PN suitable for new designs?

A: TNY264PN is classified as Not For New Designs. For new designs, consult Power Integrations' current product portfolio for recommended alternatives within the TinySwitch®-II or successor series.

Q: What fault protection features are included?

A: Both TNY264P and TNY264PN include Current Limiting, Open Loop, Over Temperature, and Short Circuit protection. These features are integrated into the IC and do not require external components for basic protection functionality.
