PVC6Q203A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6Q203A01B00 is a 20 kOhms 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, side adjustment, and PC pin termination. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The PVC6 series has been superseded by newer trimmer potentiometer designs that maintain electrical compatibility while offering improved compliance and availability.

Substitute Part Grouping Explanation

Substitution for the PVC6Q203A01B00 is determined by matching the following critical parameters: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn count, side adjustment mechanism, through-hole mounting, and PC pin termination. Two substitute parts meet these electrical and mechanical requirements:

3362M-1-203LF (Bourns Inc., Trimpot® 3362 - Sealed series) is a direct manufacturer equivalent with identical electrical specifications and active product status. The primary difference is the resistive material composition (Cermet instead of Ceramic) and improved RoHS3 compliance.

72XR20KLF (TT Electronics / BI Technologies, 72 series) is a similar substitute meeting all electrical parameters with active product status and RoHS3 compliance. Physical dimensions differ (square 0.375" x 0.375" versus rectangular configurations), requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

3362M-1-203LF is the primary substitute for new designs and production transitions. It maintains Bourns Inc. manufacturing continuity, carries active product status, and achieves ROHS3 compliance. The Cermet resistive material provides equivalent electrical performance to the ceramic material in the obsolete PVC6Q203A01B00. This part is recommended for applications requiring regulatory compliance and long-term supply assurance.

72XR20KLF serves as an alternative substitute when supply constraints or cost considerations apply. As an active product from TT Electronics / BI Technologies with ROHS3 compliance and REACH unaffected status, it meets all electrical specifications. Physical dimensions are larger (square 0.375" x 0.375" footprint), requiring PCB layout compatibility assessment before selection.

Frequently Asked Questions (FAQ)

Q: Can 3362M-1-203LF directly replace PVC6Q203A01B00 without circuit modification?

A: Yes. Both parts share identical electrical specifications (20 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn, side adjustment, PC pins). Physical dimensions differ slightly (0.275" x 0.260" versus 0.315" x 0.272"), requiring PCB footprint verification but no circuit changes.

Q: What is the difference between Ceramic and Cermet resistive materials in these trimmers?

A: Both materials meet the specified electrical parameters for this application. Cermet (ceramic-metal composite) used in the 3362M and 72XR series provides improved stability and is standard in modern trimmer potentiometer designs. The PVC6Q203A01B00 uses ceramic material, which is now obsolete in this product category.

Q: Is 72XR20KLF suitable for space-constrained PCB layouts?

A: No. The 72XR20KLF has a larger square footprint (0.375" x 0.375") compared to the rectangular PVC6Q203A01B00 (0.315" x 0.272"). The 3362M-1-203LF offers a more compact rectangular form factor (0.275" x 0.260") and is preferred for space-limited applications.

Q: What compliance advantages do the substitute parts offer?

A: Both 3362M-1-203LF and 72XR20KLF achieve ROHS3 compliance, addressing regulatory requirements that the obsolete PVC6Q203A01B00 does not meet. The 3362M-1-203LF is REACH Affected, while the 72XR20KLF is REACH Unaffected. Selection depends on specific regulatory requirements for your application region.

Q: Are there packaging differences between these substitutes?

A: Yes. The PVC6Q203A01B00 is supplied in standard packaging (not specified). The 3362M-1-203LF is packaged in Tube format, while the 72XR20KLF is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.
