CT-94P-204 Equivalent & Substitute Parts

Part Overview

The CT-94P-204 is a 200 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 requiring this resistance value and power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CT-94P-204 is determined by strict equivalence in the following critical parameters: resistance value (200 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

The identified substitutes maintain these core electrical and mechanical specifications. Variations in secondary parameters such as number of turns, physical dimensions, and product status are noted but do not prevent functional substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

CT-94EP204 (Nidec Components Corporation) is the direct functional equivalent with active product status and ROHS3 compliance. This substitute maintains all critical electrical parameters and is recommended for applications requiring current manufacturing support and regulatory compliance.

3296P-1-204 (Bourns Inc.) provides functional equivalence with active product status. This substitute differs in turn count (25 turns versus 18 turns) and does not carry RoHS3 compliance. Selection of this part should be based on application requirements regarding adjustment resolution and regulatory environment.

Frequently Asked Questions (FAQ)

Q: Can CT-94EP204 directly replace CT-94P-204 in existing designs? A: Yes. CT-94EP204 maintains identical electrical specifications (200 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical interface (through-hole PC pins, side adjustment, cermet material). Physical dimensions differ slightly (square 9.60mm x 9.60mm versus rectangular 9.60mm x 4.80mm), requiring PCB layout verification.

Q: What is the significance of the 18-turn versus 25-turn difference? A: Turn count affects adjustment resolution. The 3296P-1-204 with 25 turns provides finer adjustment granularity compared to the 18-turn CT-94P-204. Both maintain the same electrical performance and are functionally equivalent for applications where adjustment resolution is not a critical constraint.

Q: Are there RoHS compliance considerations for substitution? A: CT-94EP204 is ROHS3 compliant, making it suitable for applications with RoHS requirements. The original CT-94P-204 and 3296P-1-204 are non-compliant. Regulatory environment and end-use application determine whether RoHS compliance is mandatory.

Q: How do physical dimensions affect substitution? A: CT-94P-204 has a rectangular footprint (9.60mm x 4.80mm), while CT-94EP204 is square (9.60mm x 9.60mm) and 3296P-1-204 is rectangular (9.53mm x 4.83mm). PCB layout and available mounting space must accommodate the selected substitute's physical dimensions.

Q: What packaging formats are available? A: CT-94EP204 is supplied in bulk packaging, while 3296P-1-204 is supplied in tube packaging. Packaging selection depends on procurement volume and handling requirements.
