TC1263-5.0VOATR Equivalent & Substitute Parts

Part Overview

The TC1263-5.0VOATR is a linear voltage regulator IC from Microchip Technology designed for positive fixed 5V output applications. This Surface Mount device delivers 500mA output current with a maximum dropout voltage of 0.65V at full load, making it suitable for low-power embedded systems and portable electronics requiring stable 5V regulation. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to packaging availability, supply chain constraints, or specific form factor requirements while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution of the TC1263-5.0VOATR is based on strict equivalence across all critical electrical and mechanical parameters. The primary differentiator between the main part and its substitute is packaging format. Both the TC1263-5.0VOATR (Tape & Reel) and TC1263-5.0VOA (Tube) share identical electrical specifications, including output voltage, current rating, dropout characteristics, quiescent current, PSRR performance, temperature range, and protection features. The substitution is valid because both parts use the same 8-SOIC package footprint and are manufactured by the same supplier under the same base product number (TC1263). Packaging differences do not affect circuit performance or PCB assembly compatibility when using standard pick-and-place equipment.

Parameter Comparison

Engineering Selection Recommendations

Both TC1263-5.0VOATR and TC1263-5.0VOA are active production parts from Microchip Technology with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements. The TC1263-5.0VOATR in Tape & Reel format is optimized for high-volume automated assembly operations using standard pick-and-place equipment. The TC1263-5.0VOA in Tube packaging is suitable for lower-volume production, manual assembly, or applications where component traceability through tube packaging is preferred. Both parts deliver identical electrical performance and thermal characteristics across the full operating temperature range of -40°C to 125°C. No functional or reliability differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can TC1263-5.0VOA be used as a direct replacement for TC1263-5.0VOATR on the same PCB?

A: Yes. Both parts use identical 8-SOIC package footprints and pin configurations. No PCB redesign or layout modifications are required. The only difference is the supply packaging format (Tube vs. Tape & Reel).

Q: Are there any electrical performance differences between these two part numbers?

A: No. Both parts share identical electrical specifications including 5V output voltage, 500mA current rating, 0.65V maximum dropout voltage, 130 µA quiescent current, and 64dB PSRR at 1kHz.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging is designed for automated high-speed pick-and-place assembly lines. Tube packaging is used for manual assembly, lower-volume production runs, or component storage. Both formats contain the same die and offer identical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TC1263-5.0VOATR and TC1263-5.0VOA are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I specify for a new design?

A: Selection depends on production volume and assembly method. For high-volume automated assembly, specify TC1263-5.0VOATR (Tape & Reel). For lower volumes or manual assembly, TC1263-5.0VOA (Tube) is appropriate. Both are equally suitable from an electrical and reliability standpoint.

Q: Are there any temperature or operating condition limitations that differ between these parts?

A: No. Both parts operate identically across the full temperature range of -40°C to 125°C with the same thermal and electrical characteristics.
