MCP1631HVT-500E/ST Equivalent & Substitute Parts

Part Overview

The MCP1631HVT-500E/ST is a Sepic Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC manufactured by Microchip Technology. This active product operates as a transistor driver in a 20-TSSOP surface mount package, enabling flexible voltage conversion across a 4.6V to 16V supply range. The device incorporates enable, frequency control, and ramp control features for regulated power management applications. Finding equivalent substitute parts is necessary when the tape & reel packaging variant is unavailable or when alternative packaging formats better suit procurement requirements.

Substitute Part Grouping Explanation

The MCP1631HVT-500E/ST has one direct equivalent substitute: MCP1631HV-500E/ST. Both parts share identical electrical and mechanical specifications, including the same base product number (MCP1631), topology (Sepic), output configuration (positive step-up/step-down), supply voltage range (4.6V ~ 16V), operating temperature range (-40°C ~ 125°C), and 20-TSSOP package footprint.

The substitution is valid based on the following key parameters:

• Identical base product number and manufacturer (Microchip Technology)
• Matching topology and function (Sepic Step-Up/Step-Down)
• Identical electrical specifications (supply voltage, temperature range, control features)
• Identical package and pinout (20-TSSOP, 0.173" × 4.40mm)
• Equivalent compliance certifications (ROHS3, MSL 1)

The only difference between these parts is the packaging format: the main part is supplied in Tape & Reel (TR), while the substitute is supplied in Tube packaging. This distinction affects only procurement and handling, not electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP1631HVT-500E/ST and MCP1631HV-500E/ST are active products from Microchip Technology with full ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on packaging requirements and procurement availability:

• Use MCP1631HVT-500E/ST when tape & reel packaging is required for automated assembly processes.
• Use MCP1631HV-500E/ST when tube packaging is acceptable or preferred for manual assembly or lower-volume applications.

Both parts carry identical electrical specifications and certifications, ensuring functional interchangeability in circuit design and operation.

Frequently Asked Questions (FAQ)

Q: Are MCP1631HVT-500E/ST and MCP1631HV-500E/ST electrically identical?

A: Yes. Both parts share the same base product number, topology, supply voltage range (4.6V ~ 16V), operating temperature range (-40°C ~ 125°C), control features, and 20-TSSOP package footprint. The only difference is packaging format (tape & reel versus tube).

Q: Can I use MCP1631HV-500E/ST as a direct replacement for MCP1631HVT-500E/ST on a PCB?

A: Yes. The parts are pin-compatible and functionally equivalent. The 20-TSSOP package and pinout are identical, allowing direct substitution in circuit design and PCB layout.

Q: What is the significance of the packaging difference between these parts?

A: Packaging format affects procurement, handling, and assembly processes. Tape & reel packaging is optimized for high-volume automated assembly, while tube packaging is suitable for manual assembly or lower-volume applications. Electrical and mechanical specifications remain unchanged.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both MCP1631HVT-500E/ST and MCP1631HV-500E/ST are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: What control features are available on these devices?

A: Both parts include enable, frequency control, and ramp control features for flexible power management and regulation in step-up/step-down applications.
