CT-94X-102 Equivalent & Substitute Parts

Part Overview

The CT-94X-102 is a 1 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination, manufactured by Vishay Beyschlag/Draloric/BC Components. This component features cermet resistive material, 18-turn side adjustment, and rectangular form factor (9.60mm x 4.80mm). The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-94X-102 is determined by strict equivalence across the following critical parameters:

• 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)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Adjustment type: Side Adjustment (exact match required)

The substitute parts listed below meet all core electrical and mechanical requirements. Variations in number of turns, face dimensions within tolerance, and packaging format do not preclude substitution when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

CT-94EX102 (Nidec Components Corporation) is the primary direct substitute for CT-94X-102. This part maintains identical electrical specifications, mechanical dimensions, and turn count (18 turns). The CT-94EX102 is currently in active production status and carries RoHS3 compliance, making it suitable for applications requiring modern regulatory adherence.

3296X-1-102 (Bourns Inc.) is an alternative substitute that meets all core electrical requirements but differs in two aspects: it features 25 turns instead of 18 turns, and face dimensions are slightly larger (0.395" x 0.190" versus 0.378" x 0.189"). This part is active and available but carries REACH Affected status. Selection of this alternative requires verification that the increased turn count and dimensional variance are compatible with the target application's mechanical and functional constraints.

Frequently Asked Questions (FAQ)

Q: Can CT-94EX102 be used as a direct replacement for CT-94X-102?

A: Yes. CT-94EX102 matches all critical electrical parameters (1 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, cermet material) and maintains identical mechanical specifications (18 turns, PC pin termination, side adjustment, 9.60mm x 4.80mm face dimension). No circuit modification is required.

Q: What is the difference between CT-94EX102 and 3296X-1-102?

A: Both parts share identical electrical specifications. The primary differences are: CT-94EX102 has 18 turns with 9.60mm x 4.80mm face dimension, while 3296X-1-102 has 25 turns with 10.03mm x 4.83mm face dimension. The increased turn count in 3296X-1-102 provides finer adjustment resolution but requires verification of mechanical fit in the target application.

Q: Why is the CT-94X-102 marked as obsolete?

A: The CT-94X-102 is no longer manufactured by Vishay Beyschlag/Draloric/BC Components. Active substitutes from other manufacturers (Nidec Components Corporation and Bourns Inc.) are available to support continued production and field replacement requirements.

Q: Are there RoHS compliance differences between the substitutes?

A: Yes. CT-94EX102 is RoHS3 compliant, while 3296X-1-102 is RoHS non-compliant. Applications requiring RoHS compliance should specify CT-94EX102. The original CT-94X-102 is also RoHS non-compliant.

Q: Does packaging format affect substitution eligibility?

A: No. CT-94EX102 is supplied in Bulk packaging, while 3296X-1-102 is supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility. Selection should be based on procurement and inventory management requirements.

Q: What is the REACH status difference between the substitutes?

A: CT-94EX102 is REACH Unaffected, while 3296X-1-102 is REACH Affected. Applications subject to REACH regulations should prioritize CT-94EX102. The original CT-94X-102 is REACH Unaffected.
