CT-94Z-102 Equivalent & Substitute Parts

Part Overview

The CT-94Z-102 is a 1 kOhms 0.5W through-hole trimmer potentiometer with cermet resistive material, 18-turn side adjustment, and PC pin termination. Manufactured by Vishay Beyschlag/Draloric/BC Components, this part is classified as obsolete. Due to its obsolete status and limited availability from original sources, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure supply chain reliability for applications requiring this component specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-94Z-102 are identified based on electrical and mechanical parameter compatibility. The primary substitution criteria are:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.5W/1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

Two substitute parts meet these criteria with allowable variations in number of turns and physical dimensions within acceptable engineering tolerances for PCB layout and mechanical assembly.

Parameter Comparison

Engineering Selection Recommendations

CT-94EZ102 is the direct functional equivalent with identical electrical specifications and physical dimensions. This part is manufactured by Nidec Components Corporation and maintains active product status with RoHS3 compliance, making it suitable for applications requiring modern regulatory compliance.

3296Z-1-102 is a manufacturer-recommended alternative from Bourns Inc. with identical electrical specifications. This part features 25 turns instead of 18 turns and slightly larger physical dimensions (0.395" x 0.190" versus 0.378" x 0.189"). The increased turn count provides finer adjustment resolution. Physical dimension differences require PCB layout verification before implementation. This part maintains active product status but is RoHS non-compliant.

Selection between CT-94EZ102 and 3296Z-1-102 depends on regulatory requirements (RoHS compliance), available PCB space for the slightly larger footprint, and adjustment resolution needs.

Frequently Asked Questions (FAQ)

Q: Can CT-94EZ102 be used as a direct replacement for CT-94Z-102?

A: Yes. CT-94EZ102 matches all electrical parameters (1 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 18 turns) and physical dimensions (0.378" x 0.189" face). No PCB layout modifications are required.

Q: What is the difference between CT-94EZ102 and 3296Z-1-102?

A: Both parts share identical electrical specifications. The primary differences are: 3296Z-1-102 has 25 turns versus 18 turns (finer adjustment), slightly larger physical dimensions (0.395" x 0.190" versus 0.378" x 0.189"), and different manufacturer (Bourns versus Nidec). PCB layout verification is required for 3296Z-1-102 due to dimension differences.

Q: Does the number of turns affect electrical performance?

A: Number of turns affects adjustment resolution and mechanical characteristics, not electrical performance. Both 18-turn and 25-turn versions deliver identical resistance, power rating, tolerance, and temperature coefficient specifications.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. CT-94EZ102 is RoHS3 compliant. CT-94Z-102 and 3296Z-1-102 are RoHS non-compliant. Select CT-94EZ102 for applications requiring RoHS compliance.

Q: Can 3296Z-1-102 be used in the same PCB footprint as CT-94Z-102?

A: Physical dimension verification is required. 3296Z-1-102 is 0.395" x 0.190" versus CT-94Z-102 at 0.378" x 0.189". The 0.017" width and 0.001" height differences may affect PCB layout depending on component spacing and clearance requirements.
