TNY263P Equivalent & Substitute Parts

Part Overview

The TNY263P is an offline switch flyback converter IC manufactured by Power Integrations, part of the TinySwitch®-II series. This 8-DIP through-hole component integrates a 700V breakdown voltage switch with isolated flyback topology, operating at 132kHz switching frequency with 7.5W power capability. The TNY263P is classified as obsolete, making identification of functionally equivalent substitute parts essential for design continuity and procurement planning. Substitution is necessary to ensure access to components with current manufacturing status and compliance certifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNY263P is based on strict electrical and mechanical parameter matching within the TinySwitch®-II product family. The primary substitute TNY263PN maintains identical electrical specifications: 700V breakdown voltage, 132kHz switching frequency, 7.5W power rating, 65% duty cycle, isolated flyback topology, and identical fault protection features (current limiting, open loop, over temperature, short circuit protection). Both parts feature EN control capability and operate across the same temperature range (-40°C to 150°C junction temperature).

The mechanical compatibility is ensured through identical packaging: 8-DIP (0.300", 7.62mm) with 7 leads in 8-PDIP-B supplier device package, both mounted through-hole. The critical distinction between TNY263P and TNY263PN is product status and compliance certification. TNY263P is obsolete, while TNY263PN carries "Not For New Designs" status with RoHS Compliant certification, making it the direct functional equivalent for ongoing production and new applications.

Parameter Comparison

Engineering Selection Recommendations

The TNY263PN is the direct electrical and mechanical equivalent of the TNY263P. Selection of TNY263PN over TNY263P is driven by product lifecycle status and regulatory compliance. TNY263P is classified as obsolete, indicating discontinued manufacturing and limited availability. TNY263PN carries RoHS Compliant certification, meeting current environmental and regulatory requirements for component procurement in regulated markets.

For applications currently using TNY263P, TNY263PN provides identical electrical performance and pin-compatible through-hole mounting without circuit redesign. Both parts share REACH Unaffected status and EAR99 export classification. The substitution is direct: no circuit modifications, no thermal management changes, and no control logic adjustments are required.

For new designs, TNY263PN is the appropriate selection from the TinySwitch®-II family at this power and voltage specification level. Procurement should prioritize TNY263PN due to superior availability (31,200 pcs in stock versus 1,208 pcs for TNY263P) and compliance certification alignment with modern manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can TNY263PN be used as a direct replacement for TNY263P in existing designs?

A: Yes. TNY263PN is electrically and mechanically identical to TNY263P. Both parts feature 700V breakdown voltage, 132kHz switching frequency, 7.5W power rating, isolated flyback topology, and identical fault protection. Pin configuration and 8-DIP through-hole package are identical. No circuit modifications are required.

Q: What is the difference between TNY263P and TNY263PN?

A: The primary differences are product status and compliance certification. TNY263P is obsolete; TNY263PN is not for new designs. TNY263PN is RoHS Compliant; TNY263P is RoHS non-compliant. Electrical specifications and package are identical.
