PVC6H253C01B00 Equivalent & Substitute Parts

Part Overview

The PVC6H253C01B00 is a 25 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, side adjustment, and PC pin termination. This component is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement continuity. The part operates with ±10% tolerance and ±100ppm/°C temperature coefficient across a single turn adjustment range.

Key Parameters

Substitute Part Grouping Explanation

The 3362X-1-253LF qualifies as a direct substitute for the PVC6H253C01B00 based on the following critical parameters:

• Identical resistance value: 25 kOhms
• Matching power rating: 0.5W (1/2W)
• Equivalent tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Same number of turns: 1
• Matching adjustment type: Side Adjustment
• Identical mounting type: Through Hole
• Matching termination style: PC Pins
• Equivalent RoHS3 compliance

The primary difference is the resistive material composition (Cermet vs. Ceramic) and physical dimensions. The 3362X-1-253LF features a slightly smaller footprint (0.275" x 0.260" vs. 0.315" x 0.272") and uses Cermet material instead of ceramic, which does not affect electrical performance for the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The 3362X-1-253LF is the appropriate substitute for the obsolete PVC6H253C01B00. Both components are manufactured by Bourns Inc. and maintain identical electrical specifications across all critical parameters: resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics.

The 3362X-1-253LF offers the advantage of active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance, supporting regulatory requirements for new designs and manufacturing processes.

The dimensional difference (smaller footprint on the 3362X-1-253LF) requires PCB layout verification to confirm mechanical fit within existing designs. The shift from ceramic to Cermet resistive material does not impact electrical performance for the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-253LF be used as a direct replacement for the PVC6H253C01B00?

A: Yes. Both components share identical electrical specifications: 25 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and single-turn side adjustment with PC pin termination. PCB layout must accommodate the slightly smaller physical dimensions of the 3362X-1-253LF.

Q: What is the difference between ceramic and Cermet resistive materials in this application?

A: Both materials meet the specified electrical parameters. Cermet (ceramic-metal composite) used in the 3362X-1-253LF provides enhanced stability and is the material used in the active Trimpot® 3362 series. The ceramic material in the PVC6H253C01B00 is no longer produced.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant. The 3362X-1-253LF is REACH Affected, while the PVC6H253C01B00 is REACH Unaffected. Verify REACH compliance requirements for your specific application and end-use market.

Q: What is the impact of the dimensional difference on PCB design?

A: The 3362X-1-253LF is approximately 0.04" smaller in both width and height. Existing PCB layouts designed for the PVC6H253C01B00 require verification to confirm mechanical clearance and mounting hole alignment remain acceptable.

Q: Is the 3362X-1-253LF available in the same packaging as the PVC6H253C01B00?

A: The 3362X-1-253LF is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.
