Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP4361T-502E/ST is determined by strict equivalence across the following critical parameters:

• Resistance value: 5kΩ
• Circuit count: 4 independent potentiometer circuits
• Tap resolution: 257 taps
• Control interface: SPI protocol
• Memory architecture: Non-volatile storage
• Supply voltage compatibility: 1.8V ~ 5.5V
• Package form factor: 20-TSSOP
• Temperature operating range: -40°C ~ 125°C

The identified substitute part MCP4361-502E/ST maintains identical electrical specifications and mechanical compatibility. The primary distinction between the main part and substitute is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Tube packaging. Both variants are manufactured by Microchip Technology under the WiperLock™ series designation and share the same base product number MCP4361.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP4361T-502E/ST and MCP4361-502E/ST are active products manufactured by Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain logistics:

• Tape & Reel (TR) format is standard for high-volume automated assembly operations and provides optimal component density for pick-and-place equipment.
• Tube packaging is suitable for lower-volume applications, manual assembly, or situations where component handling and storage differ from automated production environments.

Both variants maintain full compliance with ROHS3 and REACH regulations. Moisture sensitivity level MSL 1 indicates unlimited shelf life under standard storage conditions. The WiperLock™ series designation confirms implementation of Microchip's non-volatile memory locking feature, ensuring wiper position retention across power cycles.

Frequently Asked Questions (FAQ)

Q: Can MCP4361-502E/ST (Tube) be used as a direct replacement for MCP4361T-502E/ST (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Substitution is valid for any application where the MCP4361T-502E/ST is specified, provided the receiving assembly process can accommodate Tube packaging.

Q: What is the significance of the "T" designation in MCP4361T-502E/ST?

A: The "T" in the part number indicates Tape & Reel packaging format. The substitute part MCP4361-502E/ST without the "T" designation uses Tube packaging. All other specifications remain identical.

Q: Are there any electrical performance differences between these two parts?

A: No. Both parts share identical electrical characteristics: 5kΩ resistance, 257 taps, 4 circuits, SPI interface, non-volatile memory, 1.8V ~ 5.5V supply range, ±20% tolerance, 150ppm/°C temperature coefficient, and -40°C ~ 125°C operating range.

Q: What is the wiper resistance specification?

A: The typical wiper resistance is 75Ω for both parts. This represents the on-resistance of the internal switch connecting the wiper to the resistor network.

Q: Are both parts RoHS compliant?

A: Yes. Both MCP4361T-502E/ST and MCP4361-502E/ST are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.

Q: What does MSL 1 (Unlimited) mean for storage?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under standard storage conditions (typically 23°C ± 2°C, 45% ± 5% relative humidity). No special moisture control measures are required during storage or handling.
