CT-94P-200 Equivalent & Substitute Parts

Part Overview

The CT-94P-200 is a 20 Ohm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based component features PC pin termination and side adjustment with an 18-turn configuration. The part is currently obsolete, making identification of compatible substitutes essential for ongoing maintenance, repair, and legacy system support. Equivalent parts must maintain the same electrical specifications and physical form factor to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CT-94P-200 is determined by strict equivalence in the following critical parameters:

• Resistance value: 20 Ohms (exact match required)
• Power rating: 0.5W minimum (equal or greater acceptable)
• Termination style: PC Pins (through-hole compatible)
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Physical form factor: Rectangular package compatible with 0.378" x 0.189" footprint tolerance

The 3296P-1-200 from Bourns Inc. qualifies as a direct substitute based on matching resistance, power rating, termination style, adjustment type, and resistive material. Minor variations in turn count (25 vs. 18) and temperature coefficient do not preclude substitution when the application does not require the specific turn count or temperature stability of the original part.

Parameter Comparison

Engineering Selection Recommendations

The 3296P-1-200 is the qualified substitute for the obsolete CT-94P-200. Selection is based on the following engineering criteria:

• Both parts maintain identical electrical specifications for resistance, power rating, and tolerance
• Physical dimensions are within acceptable tolerance for direct PCB mounting
• Both components use cermet resistive material with side adjustment and PC pin termination
• The 3296P-1-200 is an active product with current manufacturing support, addressing the obsolescence of the CT-94P-200
• The substitute exhibits superior temperature stability (±100ppm/°C vs. ±250ppm/°C), providing enhanced performance in temperature-sensitive applications
• Increased turn count (25 vs. 18) provides finer adjustment resolution without affecting electrical equivalence
• Both parts carry identical RoHS non-compliance status, maintaining regulatory consistency in legacy system applications

Frequently Asked Questions (FAQ)

Q: Can the 3296P-1-200 be used as a direct replacement for the CT-94P-200 in existing PCB assemblies?

A: Yes. The 3296P-1-200 is dimensionally and electrically compatible with the CT-94P-200. Face dimensions (0.375" x 0.190" vs. 0.378" x 0.189") are within standard PCB tolerance, and both components use identical PC pin termination and through-hole mounting.

Q: What is the significance of the different turn counts (18 vs. 25)?

A: Turn count affects adjustment resolution. The 3296P-1-200 with 25 turns provides finer adjustment granularity than the 18-turn CT-94P-200. This does not prevent substitution; it enhances adjustment precision in applications where fine tuning is beneficial.

Q: Does the lower temperature coefficient of the 3296P-1-200 affect compatibility?

A: No. The 3296P-1-200 exhibits superior temperature stability (±100ppm/°C vs. ±250ppm/°C). This represents an improvement over the original part and does not compromise substitution compatibility.

Q: Are there packaging differences between these parts?

A: The CT-94P-200 packaging information is not specified in the original documentation. The 3296P-1-200 is supplied in tube packaging. Verify packaging requirements for your procurement process.

Q: What is the regulatory status of the 3296P-1-200 for legacy applications?

A: Both the CT-94P-200 and 3296P-1-200 are RoHS non-compliant. For applications requiring RoHS compliance, alternative parts must be evaluated. Both parts are REACH Unaffected or REACH Affected respectively; verify REACH compliance requirements for your specific application.

Q: Is the 3296P-1-200 available in production quantities?

A: Yes. The 3296P-1-200 is an active product with current manufacturing support, ensuring availability for production and maintenance applications.
