CT-94W-202 Equivalent & Substitute Parts

Part Overview

The CT-94W-202 is a 2 kOhms 0.5W through-hole trimmer potentiometer with cermet resistive material, 18-turn top 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 relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-94W-202 is determined by strict equivalence across the following critical parameters:

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

The substitute parts identified below meet these core electrical and mechanical requirements. Variations in number of turns and physical dimensions are noted where they occur, as these parameters may affect circuit performance and PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

CT-94EW202 (Direct Substitute): This part is the primary equivalent for the CT-94W-202. It maintains identical electrical specifications, physical dimensions, and number of turns. The CT-94EW202 is manufactured by Nidec Components Corporation and carries active product status with RoHS3 compliance, making it suitable for new designs and production environments with RoHS requirements.

3296W-1-202 (MFR Recommended Alternative): This Bourns Trimpot® 3296 sealed trimmer potentiometer meets all core electrical parameters but differs in two aspects: it features 25 turns instead of 18, and physical dimensions vary slightly (0.375" x 0.190" versus 0.378" x 0.189"). The increased turn count provides finer adjustment resolution. This part is active and available but remains RoHS non-compliant. PCB layout verification is required due to dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can CT-94EW202 be used as a direct replacement for CT-94W-202?

A: Yes. The CT-94EW202 is electrically and mechanically equivalent to the CT-94W-202. Both parts share identical resistance, power rating, tolerance, temperature coefficient, number of turns, and physical dimensions. The primary difference is product status: CT-94EW202 is active and RoHS3 compliant, whereas CT-94W-202 is obsolete.

Q: What is the impact of using 3296W-1-202 instead of CT-94W-202?

A: The 3296W-1-202 meets all electrical specifications but introduces two considerations. First, it has 25 turns versus 18 turns, providing finer adjustment granularity. Second, physical dimensions differ slightly (0.375" x 0.190" versus 0.378" x 0.189"), which may affect PCB layout compatibility. Verify footprint clearance before substitution.

Q: Are there RoHS compliance implications?

A: The CT-94W-202 is RoHS non-compliant. The CT-94EW202 substitute is RoHS3 compliant, making it preferable for applications subject to RoHS regulations. The 3296W-1-202 remains RoHS non-compliant.

Q: How do packaging options differ?

A: CT-94EW202 is supplied in bulk packaging, while 3296W-1-202 is supplied in tube packaging. Packaging selection depends on production volume and handling requirements.

Q: Can these parts be used interchangeably in existing designs?

A: CT-94EW202 is a direct interchange with no design modifications required. The 3296W-1-202 requires PCB layout verification due to dimensional differences and should be evaluated for turn-count impact on circuit performance.
