X9317WPI-2.7 Equivalent & Substitute Parts

Part Overview

The X9317WPI-2.7 is a digital potentiometer manufactured by Renesas Electronics Corporation, classified as a data acquisition component. This 10kΩ device features 100 taps with Up/Down (U/D, INC, CS) interface control, housed in an 8-PDIP through-hole package. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the X9317WPI-2.7 is determined by the following critical parameters:

• Resistance value: 10kΩ (exact match required)
• Number of taps: 100 (exact match required)
• Interface protocol: Up/Down (U/D, INC, CS) (exact match required)
• Supply voltage range: 2.7V ~ 5.5V (minimum requirement)
• Memory type: Non-Volatile (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Taper characteristic: Linear (exact match required)

Two substitute parts meet these criteria with variations in packaging and product status:

1. X9317WS8IZ-2.7 (Direct substitute): Identical electrical specifications with surface-mount packaging (8-SOIC). Active product status with RoHS3 compliance.

2. DS1804-010+ (Similar substitute): Identical electrical specifications and through-hole packaging (8-PDIP). Active product status with RoHS3 compliance. Manufactured by Analog Devices Inc./Maxim Integrated.

Parameter Comparison

Engineering Selection Recommendations

X9317WS8IZ-2.7 is the primary direct substitute for the X9317WPI-2.7. Both parts are manufactured by Renesas Electronics and share identical electrical specifications. The X9317WS8IZ-2.7 is currently in active production with RoHS3 compliance. The primary difference is packaging: X9317WS8IZ-2.7 uses surface-mount 8-SOIC technology versus the through-hole 8-DIP of the original part. This substitution requires PCB redesign for surface-mount assembly.

DS1804-010+ is a functionally equivalent alternative manufactured by Analog Devices Inc./Maxim Integrated. It maintains the same through-hole 8-DIP package as the original X9317WPI-2.7, eliminating the need for PCB layout changes. The DS1804-010+ is active and RoHS3 compliant. The temperature coefficient differs (750ppm/°C versus 300ppm/°C), which may impact precision applications requiring tighter thermal stability.

Both substitutes are RoHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet.

Frequently Asked Questions (FAQ)

Q: Can X9317WS8IZ-2.7 directly replace X9317WPI-2.7 without PCB modification?

A: No. X9317WS8IZ-2.7 uses 8-SOIC surface-mount packaging while X9317WPI-2.7 uses 8-DIP through-hole packaging. PCB redesign is required for footprint compatibility.

Q: Is DS1804-010+ a pin-compatible replacement?

A: Yes. DS1804-010+ uses the same 8-DIP (0.300", 7.62mm) through-hole package as X9317WPI-2.7, allowing direct PCB substitution without layout changes.

Q: What is the significance of the temperature coefficient difference between X9317WPI-2.7 and DS1804-010+?

A: X9317WPI-2.7 has a temperature coefficient of ±300ppm/°C while DS1804-010+ is ±750ppm/°C. In applications with wide temperature operation or requiring high precision, the lower coefficient of the Renesas part provides better stability. For general applications within the -40°C to 85°C range, both are acceptable.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both X9317WS8IZ-2.7 and DS1804-010+ are RoHS3 compliant. The original X9317WPI-2.7 is RoHS non-compliant.

Q: What are the inventory considerations for these substitutes?

A: X9317WS8IZ-2.7 has 8232 pieces in stock. DS1804-010+ has 1148 pieces in stock. Both are available as new original components.

Q: Do all three parts share the same electrical interface?

A: Yes. X9317WPI-2.7, X9317WS8IZ-2.7, and DS1804-010+ all use identical Up/Down (U/D, INC, CS) interface control, ensuring firmware and control circuit compatibility.
