Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP4261T-503E/ST is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ
• Number of circuits: 2
• Number of taps: 257
• Interface protocol: SPI
• Memory configuration: Non-Volatile
• Supply voltage range: 1.8V ~ 5.5V
• Package type: 14-TSSOP
• Mounting technology: Surface Mount

The identified substitute part MCP4261-503E/ST differs only in packaging configuration (Tube versus Tape & Reel), while maintaining complete electrical and mechanical compatibility. All core functional parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP4261T-503E/ST and MCP4261-503E/ST are Active products manufactured by Microchip Technology with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

• MCP4261T-503E/ST in Tape & Reel packaging is suitable for high-volume automated assembly operations
• MCP4261-503E/ST in Tube packaging is suitable for lower-volume applications or manual assembly processes

Both parts meet identical electrical specifications and operating conditions. The choice between them does not affect circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can MCP4261-503E/ST replace MCP4261T-503E/ST in my design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube versus Tape & Reel). Functional performance in the circuit is unchanged.

Q: Does packaging format affect component reliability?

A: No. Packaging format affects only handling, storage, and assembly processes. The component itself and its performance characteristics remain identical regardless of whether it arrives in Tape & Reel or Tube packaging.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. Regulatory and environmental compliance is equivalent.

Q: What determines if a part can substitute for the MCP4261T-503E/ST?

A: A substitute must match all electrical parameters: 50kΩ resistance, 2 circuits, 257 taps, SPI interface, non-volatile memory, 1.8V–5.5V supply range, ±20% tolerance, 150ppm/°C temperature coefficient, and 14-TSSOP package. Packaging configuration (Tape & Reel or Tube) does not affect substitution eligibility.

Q: Can I use a different resistance value or tap count?

A: No. Different resistance values or tap counts create different functional characteristics and are not substitutes. The part must maintain the exact 50kΩ/257-tap specification.
