PVC6D203A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6D203A01B00 is a 20 kOhms 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, 1-turn top adjustment, and PC pin termination. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain the core electrical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

Resistance value: 20 kOhms
Power rating: 0.5W (1/2W)
Tolerance: ±10%
Temperature coefficient: ±100ppm/°C
Number of turns: 1
Adjustment type: Top Adjustment
Mounting type: Through Hole
Termination style: PC Pins

All listed substitute parts meet these core electrical and mechanical requirements. Variations in resistive material (ceramic vs. cermet), physical dimensions, and compliance certifications do not affect functional substitutability for the specified electrical parameters.

Engineering Selection Recommendations

All substitute parts listed above satisfy the electrical and mechanical requirements of the PVC6D203A01B00. Selection should be based on the following factors:

Product Status: The main part is obsolete. All substitute parts are active, ensuring long-term availability and supply chain continuity.

Compliance Certifications: The PVC6D203A01B00 is RoHS non-compliant. Substitute parts 3362R-1-203LF, 72PR20KLF, 82PR20KLF, and CT-6ETV203 are ROHS3 compliant. Part 25PR20KLF is RoHS compliant. Selection of compliant alternatives is recommended for new designs and applications subject to RoHS regulations.

REACH Status: The main part is REACH unaffected. Substitute 3362R-1-203LF is REACH affected; all other substitutes are REACH unaffected.

Physical Dimensions: Substitute parts vary in size and form factor. Verify PCB layout compatibility before selection. The 72PR20KLF features a larger 0.375" square face; the 82PR20KLF is round with 0.250" diameter; others maintain compact square profiles near 0.27" to 0.276".

Packaging: Availability varies by packaging format (Tube, Bulk, Tape & Box). Confirm packaging requirements for assembly and inventory management.

Frequently Asked Questions (FAQ)

Q: Can I directly replace PVC6D203A01B00 with any of the listed substitutes?

A: Yes. All listed parts meet the core electrical specifications: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, and PC pin through-hole termination. Physical dimensions and resistive material differ but do not affect electrical compatibility.

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

A: Both materials meet the specified electrical parameters. Cermet (ceramic-metal composite) offers improved stability and is used in the active substitute parts. Ceramic is used in the obsolete main part. For applications requiring long-term performance and compliance, cermet-based substitutes are preferred.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. All parts meet identical electrical specifications regardless of RoHS status.

Q: Which substitute should I choose if PCB space is limited?

A: The 25PR20KLF, 3362R-1-203LF, and CT-6ETV203 maintain compact square profiles (0.27" to 0.276" face). The 72PR20KLF is larger (0.375" square), and the 82PR20KLF is round (0.250" diameter). Verify your PCB layout requirements before selection.

Q: Are there packaging considerations for high-volume production?

A: Yes. The 72PR20KLF and 82PR20KLF are supplied in bulk packaging; 3362R-1-203LF and 25PR20KLF are supplied in tubes; CT-6ETV203 is supplied in tape and box format. Confirm packaging compatibility with your assembly process and inventory management system.

Q: Can I use these substitutes in existing designs without modification?

A: Electrical substitution is direct. Verify mechanical fit on your PCB, particularly if dimensions differ from the original part. No circuit modifications are required.
