PVC6D203C01B00 Equivalent & Substitute Parts

Part Overview

The PVC6D203C01B00 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. Active alternatives with identical electrical specifications are available from multiple manufacturers, offering improved availability and extended product lifecycles.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical 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 listed substitutes meet these electrical and mechanical requirements. Resistive material variation (ceramic to cermet) is permitted within this product category as both materials satisfy the specified electrical performance. Physical dimensions vary within acceptable tolerances for through-hole PCB mounting. Product status and compliance certifications are secondary selection criteria based on application requirements.

Engineering Selection Recommendations

Primary Substitutes (Bourns Inc. Trimpot® Series): 3362R-1-203LF and 3329H-1-203LF are direct Bourns alternatives with active product status, ROHS3 compliance, and cermet resistive material. These parts maintain electrical equivalence while offering improved long-term availability. The 3362R-1-203LF provides rectangular form factor (6.99mm x 6.60mm) closest to the original PVC6D footprint. The 3329H-1-203LF offers round form factor (6.35mm diameter) for applications with different PCB layout constraints.

Secondary Substitutes (TT Electronics/BI Series): 25PR20KLF and 72PR20KLF are active alternatives from TT Electronics/BI with identical electrical specifications. The 25PR20KLF maintains square form factor (6.86mm x 6.86mm) compatible with original mounting patterns. The 72PR20KLF features larger square form factor (9.53mm x 9.53mm) suitable for applications with relaxed space constraints.

Alternative Substitute (Nidec Components Corporation): CT-6ETV203 is an active Nidec alternative with square form factor (7.00mm x 7.00mm), ROHS3 compliance, and unlimited moisture sensitivity rating. This part is suitable for applications requiring extended environmental stability.

All substitutes maintain ROHS3 or equivalent compliance status. Selection should prioritize form factor compatibility with existing PCB layouts and supplier availability requirements.

Frequently Asked Questions (FAQ)

Q: Can PVC6D203C01B00 be directly replaced with 3362R-1-203LF? A: Yes. Both parts share identical electrical specifications: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. Physical dimensions are comparable (6.90mm vs 6.99mm x 6.60mm), and both use PC pin through-hole termination. The 3362R-1-203LF is an active product with improved availability.

Q: What is the difference between ceramic and cermet resistive materials in these trimmers? A: Both ceramic and cermet materials meet the specified electrical performance parameters for this application. Cermet (ceramic-metal composite) materials used in substitute parts offer comparable temperature stability and tolerance characteristics while providing enhanced long-term reliability and availability.

Q: Are there form factor considerations when substituting? A: Yes. Physical dimensions vary among substitutes: 3362R-1-203LF (6.99mm x 6.60mm rectangular), 3329H-1-203LF (6.35mm round), 25PR20KLF (6.86mm x 6.86mm square), 72PR20KLF (9.53mm x 9.53mm square), and CT-6ETV203 (7.00mm x 7.00mm square). PCB layout and mounting hole patterns must accommodate the selected substitute's form factor.

Q: Which substitute offers the best availability? A: 3329H-1-203LF (Bourns Trimpot® 3329) currently shows the highest inventory level at 6800 pieces. 3362R-1-203LF (Bourns Trimpot® 3362) offers 1796 pieces. Both are active products with established supply chains.

Q: Are all substitutes RoHS compliant? A: Yes. All listed substitutes are RoHS compliant. The original PVC6D203C01B00 and most substitutes carry ROHS3 certification. The 25PR20KLF carries RoHS compliance status. All parts meet regulatory requirements for restricted substance elimination.

Q: Can 72PR20KLF be used in space-constrained applications? A: No. The 72PR20KLF features the largest form factor (9.53mm x 9.53mm square) among available substitutes. For space-constrained designs, 3329H-1-203LF (6.35mm round) or 3362R-1-203LF (6.99mm x 6.60mm rectangular) are more suitable options.
