CT6X254 Equivalent & Substitute Parts

Part Overview

The CT6X254 is a 250 kOhms 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based, single-turn side-adjustment component features PC pin termination and is designed for applications requiring precision resistance adjustment in compact rectangular form factors.

The CT6X254 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for systems utilizing this trimmer potentiometer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CT6X254 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance Value: 250 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)
• Number of Turns: 1 Turn (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)

The 3386H-1-254LF manufactured by Bourns Inc. meets all specified electrical parameters and functional requirements. Physical dimensions differ slightly (square 0.375" × 0.375" versus rectangular 0.323" × 0.276"), but both maintain through-hole PC pin termination compatible with standard PCB layouts designed for single-turn cermet trimmer potentiometers.

Parameter Comparison

Engineering Selection Recommendations

The 3386H-1-254LF is the qualified substitute for the CT6X254 based on complete electrical parameter equivalence and functional compatibility. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 3386H-1-254LF achieves ROHS3 compliance, whereas the CT6X254 is non-compliant. For applications subject to RoHS regulatory requirements, the Bourns substitute provides compliance alignment. Both parts maintain identical electrical performance characteristics and through-hole PC pin termination, supporting direct functional replacement in circuit designs.

Physical dimension differences (rectangular versus square footprint) require PCB layout verification to confirm mechanical fit within existing mounting constraints. Pin spacing and termination geometry remain compatible with standard through-hole assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 3386H-1-254LF directly replace the CT6X254 in existing designs?

A: Yes, provided PCB layout accommodates the square 0.375" × 0.375" footprint of the Bourns part. Electrical parameters are identical, and PC pin termination is compatible with standard through-hole assembly. Physical dimensions must be verified against available board space.

Q: What is the primary reason for substitution?

A: The CT6X254 is obsolete. The 3386H-1-254LF is an active production part with equivalent electrical specifications, ensuring component availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Yes. The 3386H-1-254LF is ROHS3 compliant, while the CT6X254 is non-compliant. For applications requiring RoHS certification, the Bourns substitute is the appropriate selection.

Q: Do the parts have identical electrical performance?

A: Yes. Both parts specify 250 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, side adjustment type, cermet resistive material, and PC pin termination.

Q: What packaging is available for the substitute part?

A: The 3386H-1-254LF is supplied in tube packaging, with 1090 pieces available in current inventory.
