PVC6E203A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6E203A01B00 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 part operates with ±10% tolerance and ±100ppm/°C temperature coefficient across a single turn adjustment range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6E203A01B00 is determined by matching the following critical parameters: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn adjustment, side adjustment type, through-hole mounting, and PC pin termination. The resistive material (ceramic or cermet) and physical dimensions are secondary considerations that do not prevent functional substitution when all primary electrical parameters align. Both substitute parts meet these core requirements and are classified as active products, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

The 3362S-1-203LF is the primary substitute for the PVC6E203A01B00. Both parts are manufactured by Bourns Inc., share identical electrical specifications, and the 3362S-1-203LF is actively produced with ROHS3 compliance. The slightly smaller face dimension (6.99mm x 6.60mm versus 8.00mm x 6.90mm) presents minimal impact on PCB layout compatibility for most applications. The cermet resistive material in the 3362S-1-203LF provides equivalent performance to the ceramic material in the original part across the specified operating parameters.

The 72XR20KLF from TT Electronics / BI Technologies is a secondary substitute option. It maintains all critical electrical parameters and active product status with ROHS3 compliance. The larger square face dimension (9.53mm x 9.53mm) requires verification of available PCB space before selection. This part is suitable for applications where the increased footprint does not present layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3362S-1-203LF directly replace the PVC6E203A01B00 without circuit redesign?

A: Yes. Both parts share identical electrical specifications: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn adjustment, side adjustment, through-hole mounting, and PC pin termination. The face dimension difference (6.99mm x 6.60mm versus 8.00mm x 6.90mm) is minor and typically accommodated within standard PCB design tolerances.

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

A: Both ceramic and cermet materials meet the specified electrical parameters for this application. Cermet (ceramic-metal composite) used in the substitute parts provides equivalent performance across the operating range while offering improved reliability characteristics in active production environments.

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

A: The 72XR20KLF has a larger square footprint (9.53mm x 9.53mm) compared to the original part (8.00mm x 6.90mm). PCB layout verification is required to confirm adequate space availability before selection.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 3362S-1-203LF and 72XR20KLF are ROHS3 compliant, addressing regulatory requirements that the obsolete PVC6E203A01B00 does not meet.

Q: What packaging formats are available for these substitutes?

A: The 3362S-1-203LF is supplied in tube packaging, while the 72XR20KLF is supplied in bulk packaging. Packaging selection depends on production volume and inventory management requirements.
