Substitute Part Grouping Explanation

Substitution of the X9259US24Z is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ (exact match required)
• Number of circuits: 4 (exact match required)
• Number of taps: 256 (exact match required)
• Interface protocol: I2C (exact match required)
• Memory type: Non-Volatile (exact match required)
• Taper characteristic: Linear (exact match required)
• Package format: 24-SOIC (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: ±300ppm/°C (exact match required)

The X9258US24IZ-2.7 meets all substitution criteria as an active product from the same manufacturer with identical functional and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the X9258US24IZ-2.7 be used as a direct replacement for the X9259US24Z?

A: Yes. Both parts share identical functional specifications including 50kΩ resistance, 4-circuit configuration, 256-tap resolution, I2C interface, linear taper, and 24-SOIC packaging. All electrical parameters, tolerance, and temperature characteristics are equivalent.

Q: What is the primary difference between these parts?

A: The X9259US24Z is obsolete, while the X9258US24IZ-2.7 is an active product. The substitute part features an extended supply voltage range (±2.7V ~ 5.5V versus 5V) and broader operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), with different wiper resistance and moisture sensitivity specifications.

Q: Are the packages physically identical?

A: Yes. Both parts use 24-SOIC packaging with 0.295" (7.50mm) width, enabling direct PCB footprint compatibility without layout modifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the X9259US24Z and X9258US24IZ-2.7 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding.

Q: What supply voltage specifications apply to each part?

A: The X9259US24Z operates at 5V supply. The X9258US24IZ-2.7 accepts ±2.7V ~ 5.5V supply voltage, providing broader operational flexibility.

Q: What are the operating temperature ranges?

A: The X9259US24Z operates from 0°C to 70°C. The X9258US24IZ-2.7 operates from -40°C to 85°C, supporting extended temperature applications.
