PVC6D501A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6D501A01B00 is a 500 Ohm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, 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 comparable electrical and mechanical specifications are available from Bourns Inc. and TT Electronics/BI.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following core parameters: resistance value (500 Ohms), 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 functional requirements. Physical dimensions vary across substitute options, requiring verification of available board space during component selection. Resistive material differs between the main part (ceramic) and substitutes (cermet), but both materials satisfy the specified electrical performance criteria.

Engineering Selection Recommendations

The 3362R-1-501LF from Bourns Inc. is the primary direct substitute, offering active product status, ROHS3 compliance, and sealed construction within the Trimpot® 3362 series. This part maintains manufacturer continuity and provides enhanced environmental protection compared to the obsolete PVC6D501A01B00.

For applications requiring alternative manufacturers, the 25PR500LF, 72PR500LF, 72PMR500LF, and 82PR500LF from TT Electronics/BI are all active products with RoHS compliance. Selection among these options depends on available printed circuit board space, as physical dimensions vary: the 25PR500LF maintains a square 0.270" x 0.270" footprint similar to the original part, while the 72-series options feature larger 0.375" x 0.375" square or 0.250" diameter round packages.

All substitutes satisfy the core electrical specifications and functional requirements of the original part. Component selection should prioritize active product status and compliance certifications appropriate for the target application environment.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-501LF directly replace the PVC6D501A01B00 without circuit modification?

A: Yes. Both parts share identical electrical specifications (500 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, through-hole mounting, PC pin termination). Physical dimensions are comparable (0.275" x 0.260" versus 0.272" x 0.272"), and the 3362R-1-501LF is sealed for enhanced reliability.

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

A: Both materials meet the specified electrical performance criteria for this application. Cermet (ceramic-metal composite) used in the substitute parts offers improved stability and environmental resistance compared to ceramic material in the original part.

Q: Which substitute should I select if board space is limited?

A: The 25PR500LF maintains the smallest footprint at 0.270" x 0.270" square, matching the original part's dimensional class. The 82PR500LF offers a round 0.250" diameter option for circular mounting patterns.

Q: Are all substitutes RoHS compliant?

A: The 3362R-1-501LF, 72PR500LF, 72PMR500LF, and 82PR500LF are ROHS3 compliant. The 25PR500LF is RoHS compliant. The original PVC6D501A01B00 is RoHS non-compliant.

Q: What packaging options are available for these substitutes?

A: The 3362R-1-501LF is supplied in tube packaging. The 25PR500LF is supplied in tube packaging. The 72PR500LF, 72PMR500LF, and 82PR500LF are supplied in bulk packaging.
