PVC6A203A01B00 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The PVC6A203A01B00 is a 20 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material and top adjustment capability. This part is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. Substitute parts maintain the core electrical specifications while offering improved availability and compliance status through active product lines from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6A203A01B00 is determined by strict equivalence across the following parameters: resistance value (20 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), mounting type (through hole), and termination style (PC pins). All identified substitute parts meet these core electrical and mechanical requirements. Variations in resistive material (ceramic to cermet), physical dimensions, and packaging format do not affect functional substitutability within the specified parameter set. Product status and compliance certifications are secondary considerations that inform selection priority but do not disqualify parts from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, the 3362P-1-203LF is the primary substitute, offering active product status, ROHS3 compliance, and continued manufacturer support from Bourns Inc. This selection maintains supply chain consistency with the original part manufacturer while ensuring regulatory compliance.

For applications requiring alternative sourcing, the 25PR20KLF, 72PR20KLF, and 82PR20KLF from TT Electronics/BI provide equivalent electrical performance with active status and RoHS compliance. These options expand supplier diversity and availability.

The CT-6ETV203 from Nidec Components Corporation represents a third-source alternative with active status and ROHS3 compliance, suitable for applications where multi-source qualification is required.

All substitute parts maintain electrical equivalence to the PVC6A203A01B00 across the specified parameter set. Selection among substitutes should prioritize active product status and compliance certifications for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-203LF directly replace the PVC6A203A01B00 in existing designs?

A: Yes. Both parts share identical electrical specifications: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, and PC pin termination. Physical dimensions differ slightly (0.275" x 0.260" versus 0.272" x 0.272"), requiring PCB layout verification for through-hole mounting compatibility.

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

A: Both materials meet the specified electrical parameters. Cermet (ceramic-metal composite) offers improved stability and is used in the active substitute parts. Material substitution does not affect functional performance within the defined parameter tolerances.

Q: Are all substitute parts RoHS compliant?

A: The 3362P-1-203LF, 25PR20KLF, 72PR20KLF, 82PR20KLF, and CT-6ETV203 are all RoHS compliant. The original PVC6A203A01B00 is RoHS non-compliant, making substitution necessary for applications requiring regulatory compliance.

Q: Do packaging differences affect substitutability?

A: Packaging format (Tube, Bulk, Tape & Box) does not affect electrical or mechanical substitutability. Packaging selection depends on procurement volume and handling requirements. All parts are functionally equivalent regardless of packaging.

Q: Which substitute offers the best long-term availability?

A: The 3362P-1-203LF (Bourns Trimpot® 3362 series) and 25PR20KLF (TT Electronics 25 series) are established active product lines with high inventory levels, providing optimal long-term supply assurance.
