TC1270ATVCTTR Equivalent & Substitute Parts

Part Overview

The TC1270ATVCTTR is a single-channel power supply supervisor IC manufactured by Microchip Technology, designed for power-on reset and simple reset applications. This device monitors a single voltage threshold at 3.08V and provides push-pull, totem pole output with active-low reset functionality. The part is actively produced and widely used in power management circuits requiring reliable supervisor functionality with a 140ms minimum reset timeout.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package type and functional specifications, ensuring direct compatibility in circuit applications.

• Voltage threshold monitoring: 3.08V
• Output configuration: Push-Pull, Totem Pole
• Reset polarity: Active Low
• Reset timeout: 140ms Minimum
• Package type: SC-74A, SOT-753 (SOT-23-5)
• Operating temperature range: -40°C ~ 125°C
• Mounting type: Surface Mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts maintain identical electrical characteristics and physical packaging, enabling direct functional replacement in circuit designs. Differences in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with full regulatory compliance. Selection between the TC1270ATVCTTR and its equivalents should be based on:

Availability and Lead Time: MAX823TEUK+T offers the highest inventory level at 35,200 units. ADM823TYRJZ-R7 provides 33,458 units. ADM6823TYRJZ-RL7 maintains 15,615 units. TC1270ATVCTTR has 6,200 units in stock. MAX6823TUK+T has limited availability at 784 units.

Packaging Format: TC1270ATVCTTR, MAX823TEUK+T, and MAX6823TUK+T are supplied in Tape & Reel format. ADM6823TYRJZ-RL7 and ADM823TYRJZ-R7 are supplied in Cut Tape & Digi-Reel format. Both formats are suitable for automated assembly processes.

Regulatory Compliance: All parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN classifications (EAR99), ensuring equivalent compliance status for export and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute TC1270ATVCTTR with MAX823TEUK+T in my circuit?

A: Yes. Both parts are parametric equivalents with identical voltage threshold (3.08V), output configuration (push-pull, totem pole), reset polarity (active low), reset timeout (140ms minimum), operating temperature range (-40°C to 125°C), and package type (SOT-23-5). Direct substitution is electrically and mechanically compatible.

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

A: Both packaging formats contain identical components. Tape & Reel is supplied on continuous carrier tape in reel format, optimized for high-volume automated assembly. Cut Tape & Digi-Reel is supplied in smaller tape segments on reels, suitable for lower-volume production or mixed-component assembly. Electrical performance and reliability are equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TC1270ATVCTTR, ADM6823TYRJZ-RL7, ADM823TYRJZ-R7, MAX6823TUK+T, and MAX823TEUK+T are all ROHS3 Compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the best availability?

A: MAX823TEUK+T offers the highest inventory at 35,200 units in stock, followed by ADM823TYRJZ-R7 at 33,458 units. Both are suitable for immediate procurement.

Q: Do all parts support the same operating temperature range?

A: Yes. All parts operate across -40°C to 125°C ambient temperature range, ensuring equivalent thermal performance in industrial and commercial applications.

Q: Can I mix different manufacturers in the same production batch?

A: Yes. All parts are parametric equivalents with identical electrical specifications and package types. Mixed sourcing from Microchip Technology, Analog Devices, and Maxim Integrated does not affect circuit performance or reliability, provided all parts meet the specified parameter requirements.
