X9C102SZ Digital Potentiometer 1kΩ Equivalent & Substitute Parts

Part Overview

The X9C102SZ is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a Data Acquisition component. It features a 1kΩ resistance value with 100 taps, linear taper, and Up/Down (U/D, INC, CS) interface control. The device operates on a 5V supply and is housed in an 8-SOIC surface mount package.

The X9C102SZ maintains Active product status. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing when the primary component becomes unavailable or when design requirements necessitate components with extended operating ranges or alternative supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9C102SZ is determined by the following critical parameters:

• Resistance Value: 1kΩ (exact match required)
• Number of Taps: 100 (exact match required)
• Interface Type: Up/Down (U/D, INC, CS) (exact match required)
• Package / Case: 8-SOIC (exact match required)
• Taper Configuration: Linear (exact match required)
• Memory Type: Non-Volatile (exact match required)

The CAT5113VI-01-GT3 manufactured by onsemi satisfies all critical substitution parameters. While this part carries Obsolete product status and operates across an extended supply voltage range (2.5V ~ 6V) compared to the X9C102SZ specification (5V), it maintains functional equivalence for the core digital potentiometer application. The extended operating temperature range (-40°C ~ 85°C) of the CAT5113VI-01-GT3 provides broader environmental capability than the X9C102SZ (-0°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

The X9C102SZ is the primary selection for new designs requiring an Active product status with established supply chain availability. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CAT5113VI-01-GT3 serves as a functional substitute where supply constraints on the X9C102SZ necessitate alternative sourcing. This part maintains ROHS3 compliance and REACH unaffected status. However, the Obsolete product status of the CAT5113VI-01-GT3 indicates limited long-term availability. The extended supply voltage range (2.5V ~ 6V) accommodates 5V operation and provides additional design flexibility for systems operating at lower supply voltages. The broader operating temperature range (-40°C ~ 85°C) extends environmental capability beyond the X9C102SZ specification.

Selection between these parts should prioritize supply chain continuity, long-term component availability, and specific application voltage and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the CAT5113VI-01-GT3 directly replace the X9C102SZ in existing designs?

A: Yes, the CAT5113VI-01-GT3 is functionally equivalent for the core digital potentiometer application. Both parts share identical resistance value (1kΩ), tap count (100), interface type (Up/Down U/D, INC, CS), package (8-SOIC), and taper configuration (Linear). The CAT5113VI-01-GT3 operates within the 5V supply specification of the X9C102SZ and maintains non-volatile memory functionality. No circuit modifications are required for substitution.

Q: What are the key differences between these parts?

A: The primary differences are product status, supply voltage range, operating temperature range, and temperature coefficient. The X9C102SZ is Active with a fixed 5V supply specification and 0°C ~ 70°C operating range. The CAT5113VI-01-GT3 is Obsolete but offers extended supply voltage (2.5V ~ 6V) and operating temperature (-40°C ~ 85°C) ranges, with a lower temperature coefficient (300ppm/°C versus ±600ppm/°C).

Q: Are there packaging differences between these parts?

A: No. Both the X9C102SZ and CAT5113VI-01-GT3 are housed in 8-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm Width). PCB layout and footprint compatibility are maintained.

Q: What is the significance of the Obsolete status for the CAT5113VI-01-GT3?

A: Obsolete status indicates that onsemi has discontinued active production and support for the CAT5113VI-01-GT3. While existing inventory may be available through authorized distributors, long-term supply cannot be guaranteed. This part should be considered for short-term substitution needs or where existing inventory is confirmed available.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the X9C102SZ and CAT5113VI-01-GT3 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
