Substitute Part Grouping Explanation

Substitution between MCP4261T-104E/ST and MCP4261-104E/ST is determined by equivalence in all critical electrical and mechanical parameters. Both parts share identical specifications across resistance value, circuit count, tap resolution, SPI interface protocol, non-volatile memory architecture, supply voltage range, tolerance, temperature coefficient, operating temperature range, wiper resistance, and 14-TSSOP package footprint.

The only difference between these parts is the supplier packaging configuration: MCP4261T-104E/ST is supplied in Tape & Reel (TR) format, while MCP4261-104E/ST is supplied in Tube format. Both packaging methods preserve component integrity and functionality. The substitution is valid when the receiving application can accommodate either packaging type during assembly or component procurement workflows.

Key parameters determining substitution eligibility:

• Resistance value: 100kΩ
• Circuit configuration: 2 circuits
• Tap resolution: 257 taps
• Interface protocol: SPI
• Memory persistence: Non-volatile
• Supply voltage compatibility: 1.8V ~ 5.5V
• Package footprint: 14-TSSOP
• Thermal specifications: -40°C ~ 125°C operating range

Parameter Comparison

Engineering Selection Recommendations

Both MCP4261T-104E/ST and MCP4261-104E/ST are Active products manufactured by Microchip Technology with identical electrical specifications and compliance certifications. Selection between these parts should be based on procurement and assembly requirements:

MCP4261T-104E/ST in Tape & Reel format is suitable for high-volume automated assembly operations where reel-fed component placement equipment is utilized. This packaging format optimizes pick-and-place machine compatibility and reduces manual handling.

MCP4261-104E/ST in Tube packaging is suitable for lower-volume applications, manual assembly workflows, or situations where component storage in tube format aligns with existing inventory management systems.

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions. The WiperLock™ series designation confirms non-volatile memory retention across both variants.

Frequently Asked Questions (FAQ)

Q: Are MCP4261T-104E/ST and MCP4261-104E/ST electrically identical?

A: Yes. Both parts are manufactured by Microchip Technology with identical electrical specifications including 100kΩ resistance, 2-circuit configuration, 257-tap resolution, SPI interface, non-volatile memory, 1.8V to 5.5V supply voltage range, and -40°C to 125°C operating temperature range.

Q: What is the difference between these two part numbers?

A: The only difference is the supplier packaging format. MCP4261T-104E/ST is supplied in Tape & Reel (TR) format, while MCP4261-104E/ST is supplied in Tube format. Both packaging methods preserve component functionality and integrity.

Q: Can I use MCP4261-104E/ST as a direct replacement for MCP4261T-104E/ST in my design?

A: Yes, from an electrical and mechanical standpoint. The 14-TSSOP package footprint is identical, and all electrical parameters match. Substitution feasibility depends on your assembly process compatibility with Tube packaging instead of Tape & Reel format.

Q: Do both parts have the same PCB footprint?

A: Yes. Both parts use the 14-TSSOP package with identical dimensions (0.173" width, 4.40mm). PCB layout and schematic connections remain unchanged between the two variants.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance status and MSL Level 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: Which packaging format should I choose for my application?

A: Choose Tape & Reel (MCP4261T-104E/ST) for automated high-volume assembly with reel-fed placement equipment. Choose Tube (MCP4261-104E/ST) for manual assembly, lower-volume production, or when tube-based inventory management is preferred.

Q: Is the WiperLock™ feature present in both parts?

A: Yes. Both MCP4261T-104E/ST and MCP4261-104E/ST belong to the WiperLock™ series, confirming non-volatile memory functionality for persistent wiper position storage.
