Key Parameters

Substitute Part Grouping Explanation

Substitution of the X9C102PZ is determined by strict equivalence across the following critical parameters:

• Resistance value: 1k Ohm
• Number of taps: 100
• Number of circuits: 1
• Interface type: Up/Down (U/D, INC, CS)
• Memory type: Non-Volatile
• Supply voltage: 5V
• Taper: Linear
• Temperature coefficient: ±600ppm/°C
• Operating temperature range: 0°C ~ 70°C
• Wiper resistance: 40 Ohms (Typ)
• Tolerance: ±20%
• Compliance: ROHS3 Compliant, REACH Unaffected

The X9C102SZ qualifies as a direct substitute based on identical electrical and functional specifications. The primary distinction is the mounting technology: the X9C102PZ uses Through Hole mounting (8-DIP package), while the X9C102SZ uses Surface Mount technology (8-SOIC package). Both devices share the same base product number (X9C102) and maintain full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The X9C102SZ is the primary substitute for the X9C102PZ. Both devices are manufactured by Renesas Electronics Corporation and maintain identical electrical specifications, functional behavior, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The X9C102PZ is Obsolete, while the X9C102SZ maintains Active product status, ensuring continued availability and manufacturer support. Selection between these parts depends on the application's mounting requirements: Through Hole (8-DIP) for the X9C102PZ or Surface Mount (8-SOIC) for the X9C102SZ. PCB layout and assembly process capabilities determine the appropriate choice.

Both devices are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the X9C102SZ directly replace the X9C102PZ in an existing design?

A: Electrical and functional compatibility is complete. The X9C102SZ is electrically identical to the X9C102PZ. However, the mounting technology differs: X9C102PZ uses Through Hole (8-DIP), while X9C102SZ uses Surface Mount (8-SOIC). PCB redesign is required if switching between these packages.

Q: What is the primary difference between X9C102PZ and X9C102SZ?

A: The devices share identical electrical specifications, resistance values, tap counts, interface protocols, and operating parameters. The sole difference is the package type: 8-DIP (Through Hole) versus 8-SOIC (Surface Mount).

Q: Is the X9C102SZ still available from the manufacturer?

A: Yes. The X9C102SZ maintains Active product status with Renesas Electronics Corporation, ensuring ongoing availability and manufacturer support. The X9C102PZ is classified as Obsolete.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the X9C102PZ and X9C102SZ are ROHS3 Compliant and REACH Unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What interface protocol does the X9C102PZ use?

A: The X9C102PZ uses an Up/Down (U/D, INC, CS) interface for digital control of the potentiometer resistance setting.

Q: Does the X9C102PZ retain its resistance setting after power loss?

A: Yes. The X9C102PZ features non-volatile memory, which preserves the resistance setting across power cycles.
