TC110501ECTTR Equivalent & Substitute Parts

Part Overview

The TC110501ECTTR is a boost regulator positive output step-up DC-DC controller IC manufactured by Microchip Technology in SOT-23-5 surface mount packaging. This active product functions as a transistor driver for single-output boost topology applications with a supply voltage range of 2V to 10V and switching frequency between 100kHz and 300kHz. Substitute parts are necessary when the primary part is unavailable, when alternative packaging formats are required, or when different switching frequency characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC110501ECTTR is determined by the following critical parameters:

• Topology & Function: All substitute parts must implement boost (step-up) DC-DC controller functionality with positive output configuration and single output
• Output Type: Transistor driver output type required
• Package Compatibility: SC-74A / SOT-753 surface mount package with SOT-23-5 supplier device package
• Operating Temperature Range: -40°C to 85°C (TA) required
• Supply Voltage Range: Minimum 2V to 10V maximum required; substitutes with lower minimum voltage (0.9V) are acceptable as they cover the primary part's range
• Switching Frequency: Primary part operates 100kHz to 300kHz; substitutes with fixed or different frequency ranges are acceptable if within or overlapping this specification
• Duty Cycle: Maximum duty cycle of 85% to 92% acceptable; lower maximum duty cycle may limit certain applications
• Control Features: Enable function required; soft start feature in primary part is not mandatory in substitutes
• Compliance: ROHS3 compliance and active product status required

The four substitute parts listed (S-8355M50MC-MDJT2U, S-8356M50MC-MFJT2U, S-8358B50MC-NRJT2U, S-8358N50MC-O7JT2U) meet all critical substitution criteria and are manufactured by ABLIC Inc.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and identical operating temperature ranges. Selection between substitutes depends on application-specific switching frequency requirements and duty cycle constraints:

S-8356M50MC-MFJT2U offers the highest inventory availability (3827 pcs) and maintains tape & reel packaging matching the primary part format. Fixed 300kHz switching frequency and 85% maximum duty cycle are suitable for standard boost applications.

S-8358B50MC-NRJT2U provides the lowest switching frequency at 100kHz with 90% maximum duty cycle, offering the closest duty cycle match to the primary part (92%). This configuration suits applications requiring lower switching noise or reduced EMI.

S-8358N50MC-O7JT2U operates at 600kHz switching frequency with 85% maximum duty cycle, appropriate for applications requiring higher switching frequency for reduced inductor and capacitor sizes.

S-8355M50MC-MDJT2U operates at 300kHz with 85% maximum duty cycle and offers the lowest supply voltage minimum (0.9V), extending operational range below the primary part's 2V minimum.

All substitutes maintain identical package geometry, surface mount compatibility, and control feature requirements (Enable function).

Frequently Asked Questions (FAQ)

Q: Can S-8355M50MC-MDJT2U replace TC110501ECTTR in all applications?

A: S-8355M50MC-MDJT2U meets all critical substitution parameters including topology, output type, package, and operating temperature. The primary difference is fixed 300kHz switching frequency versus the primary part's 100kHz to 300kHz range, and 85% maximum duty cycle versus 92%. Applications designed for the primary part's full frequency range or requiring >85% duty cycle may require circuit redesign.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Both packaging formats contain identical components in SC-74A / SOT-753 packages. Tape & Reel (TR) is optimized for high-volume automated assembly, while Cut Tape (CT) is suitable for lower-volume or manual assembly processes. Electrical and thermal performance are identical.

Q: Why do substitute parts have lower minimum supply voltage (0.9V vs 2V)?

A: ABLIC Inc. substitute parts are designed with extended lower voltage capability. This does not affect compatibility with the primary part's 2V to 10V range; the substitutes simply operate across a wider voltage window. Applications using 2V to 10V supply voltage operate identically on both primary and substitute parts.

Q: Which substitute part has the closest electrical match to TC110501ECTTR?

A: S-8358B50MC-NRJT2U provides the closest duty cycle match at 90% maximum (versus 92% primary) and operates at 100kHz switching frequency, which is within the primary part's 100kHz to 300kHz range. This part requires the least circuit redesign for direct substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts carry ROHS3 compliance certification identical to the primary part, meeting environmental and hazardous substance restrictions for regulated markets.
