PVC6M254C01B00 Equivalent & Substitute Parts

Part Overview

The PVC6M254C01B00 is a 250 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, top adjustment, and PC pin termination. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement continuity. The part operates within a 1-turn adjustment range with ±10% tolerance and ±100ppm/°C temperature coefficient, designed for applications requiring precision variable resistance in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6M254C01B00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 250 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1-turn operation
• Adjustment type: Top adjustment
• Mounting type: Through hole
• Termination style: PC pins
• Regulatory compliance: ROHS3 compliant minimum

The 3362U-1-254LF meets all substitution criteria. While the resistive material differs (cermet vs. ceramic), both materials satisfy the electrical performance requirements within the specified tolerance and temperature coefficient ranges. The dimensional variation (rectangular vs. square face) remains within acceptable mechanical envelope tolerances for standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The 3362U-1-254LF is the direct substitute for the obsolete PVC6M254C01B00. Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications across all critical parameters: 250 kOhms resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient.

The 3362U-1-254LF carries active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance, satisfying current regulatory requirements. The cermet resistive material in the 3362U-1-254LF provides equivalent performance to the ceramic material in the original part within the specified tolerance and temperature operating ranges.

Mechanical compatibility is maintained through identical through-hole PC pin termination and comparable face dimensions. The rectangular geometry of the 3362U-1-254LF (0.275" x 0.260") accommodates standard PCB hole spacing designed for the original square geometry (0.272" x 0.272"), with dimensional differences remaining within typical PCB layout tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 3362U-1-254LF directly replace the PVC6M254C01B00 in existing designs?

A: Yes. Both parts share identical electrical specifications (250 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and identical termination style (PC pins through-hole). The dimensional difference between rectangular and square face geometries does not affect electrical performance or standard PCB mounting compatibility.

Q: What is the difference between ceramic and cermet resistive materials in these parts?

A: Ceramic and cermet materials both achieve the specified tolerance (±10%) and temperature coefficient (±100ppm/°C) for this application. Cermet material in the 3362U-1-254LF provides enhanced stability and is used in the active product line. Both materials satisfy the electrical performance requirements within the defined operating parameters.

Q: Why is the original PVC6M254C01B00 marked as obsolete?

A: The PVC6M254C01B00 has been superseded by the 3362U-1-254LF within Bourns Inc.'s product portfolio. The 3362U series represents the current generation of sealed trimmer potentiometers with equivalent electrical performance and improved long-term availability.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. The 3362U-1-254LF carries REACH Affected status, while the original part is REACH Unaffected. Current regulatory requirements should be evaluated based on end-use application and regional compliance obligations.

Q: What packaging options are available for the substitute part?

A: The 3362U-1-254LF is supplied in tube packaging, compared to the original part's standard packaging. Tube packaging is standard for active Bourns trimmer potentiometer products and accommodates typical component handling and assembly processes.
