Key Parameters

Substitute Part Grouping Explanation

Substitution for the X9250UV24 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50kΩ
• Circuit configuration: 4 circuits
• Tap resolution: 256 taps
• Interface protocol: SPI
• Memory architecture: Non-volatile
• Supply voltage: ±5V
• Package form factor: 24-TSSOP
• Electrical characteristics: Linear taper, ±20% tolerance, ±300ppm/°C temperature coefficient

The X9250UV24IZ meets all these criteria and is identified as a direct substitute. Both parts share identical electrical specifications and mechanical packaging, with the primary distinction being product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The X9250UV24IZ is the direct substitute for the obsolete X9250UV24. Both parts are manufactured by Renesas Electronics Corporation and maintain identical electrical and mechanical specifications across all critical parameters.

The X9250UV24IZ offers the following advantages:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Extended operating temperature range (-40°C to 85°C) provides broader application flexibility compared to the original part's 0°C to 70°C range
• Tube packaging format supports standard component handling and assembly processes

For applications requiring the original 0°C to 70°C operating range, the X9250UV24 specifications remain valid. However, the X9250UV24IZ is the recommended selection for new designs and ongoing production due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the X9250UV24IZ be used as a direct replacement for the X9250UV24?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance value, circuit count, tap resolution, interface protocol, supply voltage, and package form factor.

Q: What is the difference between the X9250UV24 and X9250UV24IZ?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), operating temperature range (0°C–70°C versus -40°C–85°C), and packaging format (unspecified versus tube). Electrical specifications remain identical.

Q: Does the extended operating temperature range of the X9250UV24IZ affect compatibility?

A: No. The X9250UV24IZ's extended range (-40°C to 85°C) is a superset of the original part's range (0°C to 70°C). Applications designed for the X9250UV24 operate within the X9250UV24IZ's specified temperature envelope.

Q: Are there any PCB layout or assembly considerations when substituting these parts?

A: No. Both parts use identical 24-TSSOP packaging with matching pinouts and mechanical dimensions (0.173" width, 4.40mm). No PCB redesign or assembly process modification is required.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The X9250UV24 has MSL 1 (unlimited shelf life), while the X9250UV24IZ has MSL 5 (48-hour floor life after moisture exposure). Standard component handling and storage practices accommodate MSL 5 requirements.

Q: Why is the X9250UV24 classified as obsolete?

A: The X9250UV24 has been superseded by the X9250UV24IZ. Renesas Electronics Corporation recommends the X9250UV24IZ for all new designs and ongoing production support.
