Key Parameters

Substitute Part Grouping Explanation

The MCP1631HVT-500E/SS qualifies for direct substitution with MCP1631HV-500E/SS based on the following criteria:

Both parts share identical electrical specifications across all critical parameters: Sepic topology, positive output configuration, single output phase, supply voltage range of 4.6V to 16V, control features (Enable, Frequency Control, Ramp), and operating temperature range of -40°C to 125°C. Both devices are packaged in 20-SSOP form factor with identical mechanical dimensions (0.209", 5.30mm Width). Both maintain ROHS3 compliance and MSL Level 1 rating.

The substitution is valid because the only difference between these parts is packaging format: the main part (MCP1631HVT-500E/SS) is supplied in Tape & Reel (TR) format, while the substitute (MCP1631HV-500E/SS) is supplied in Tube format. This packaging difference does not affect electrical performance, pin configuration, or functional operation.

Parameter Comparison

Engineering Selection Recommendations

Both MCP1631HVT-500E/SS and MCP1631HV-500E/SS are active products from Microchip Technology with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on procurement and assembly requirements:

Use MCP1631HVT-500E/SS when automated pick-and-place assembly processes require Tape & Reel packaging format.

Use MCP1631HV-500E/SS when manual assembly, small-volume production, or tube-based component handling is preferred.

Both parts are electrically and mechanically interchangeable with no functional differences in circuit operation.

Frequently Asked Questions (FAQ)

Q: Are MCP1631HVT-500E/SS and MCP1631HV-500E/SS pin-compatible?

A: Yes. Both parts use identical 20-SSOP package geometry with the same pin configuration, pin spacing, and mechanical dimensions (0.209", 5.30mm Width).

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment. Tube packaging supplies components in plastic tubes, suitable for manual handling and small-quantity applications. Electrical and mechanical specifications are identical.

Q: Can I substitute MCP1631HV-500E/SS for MCP1631HVT-500E/SS in production?

A: Yes, provided your assembly process can accommodate tube packaging. The electrical performance and circuit behavior are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MCP1631HVT-500E/SS and MCP1631HV-500E/SS are ROHS3 compliant with MSL Level 1 rating and REACH unaffected status.

Q: What supply voltage range do these controllers support?

A: Both parts operate with supply voltage (Vcc/Vdd) from 4.6V to 16V, supporting a wide range of input sources.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -40°C to 125°C junction temperature, covering industrial and extended temperature range requirements.
