TS1117BCP33 Equivalent & Substitute Parts

Part Overview

The TS1117BCP33 is a linear voltage regulator IC from Taiwan Semiconductor Corporation, classified as a Power Management (PMIC) component. This device delivers a fixed 3.3V output at 1A maximum current with a maximum dropout voltage of 1.5V at full load. The part is actively manufactured and widely used in embedded systems, consumer electronics, and industrial applications requiring stable low-voltage power distribution.

Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory constraints necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Both TS1117BCP33 and TS1117BCP33 ROG are active products manufactured by Taiwan Semiconductor Corporation and meet identical electrical specifications. Selection between these parts is determined by packaging and supply requirements rather than performance characteristics.

TS1117BCP33 (Tape & Reel): Suitable for high-volume production environments where components are supplied in continuous tape format for automated pick-and-place assembly.

TS1117BCP33 ROG (Cut Tape & Digi-Reel®): Appropriate for lower-volume applications, prototyping, or situations where smaller quantity procurement is required. The Digi-Reel® format provides flexibility in component quantities.

Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The identical electrical performance ensures direct substitution without circuit modification or performance impact.

Frequently Asked Questions (FAQ)

Q: Can TS1117BCP33 ROG be used as a direct replacement for TS1117BCP33?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, and operating temperature range. The difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Direct substitution is permissible without circuit redesign.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) supplies components in continuous tape format optimized for high-speed automated assembly. Cut Tape (CT) & Digi-Reel® provides components in smaller quantities with flexible reel options, suitable for lower-volume or prototype applications. Electrical performance is identical.

Q: Are there any compliance differences between the two part numbers?

A: No. Both TS1117BCP33 and TS1117BCP33 ROG are ROHS3 compliant and REACH Unaffected. Regulatory and environmental compliance is equivalent.

Q: What are the critical parameters that must match for substitution?

A: Output voltage (3.3V), output current (1A), input voltage rating (12V), dropout voltage (1.5V @ 1A), package type (TO-252-3 DPAK), and operating temperature range (-40°C to 125°C) must remain constant. All these parameters are identical between the main part and substitute.

Q: Can this regulator be used in applications requiring higher output current?

A: No. The TS1117BCP33 is rated for maximum 1A output current. Applications requiring higher current must use alternative regulators with higher current ratings.

Q: What protection features are included?

A: Both parts include Over Current and Over Temperature protection, providing internal safeguards against fault conditions.
