PVC6A503A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6A503A01B00 is a 50 kOhms 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. in the PVC6 series. This component features ceramic resistive material, PC pin termination, and top adjustment with a 1-turn configuration. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6A503A01B00 is determined by strict equivalence across the following parameters: resistance value (50 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 substitute parts listed maintain these core electrical and mechanical specifications. Variations in resistive material (ceramic to cermet), physical dimensions, and packaging do not affect functional equivalence within the allowed parameter set. Product status and compliance certifications are secondary considerations for component selection.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the PVC6A503A01B00. Selection should prioritize active product status and current compliance certifications.

The 3362P-1-503LF from Bourns Inc. is the primary substitute, maintaining manufacturer continuity while offering ROHS3 compliance and active production status. This part is available in high inventory (65,900 units) and packaged in tube format.

The TT Electronics/BI alternatives (25PR50KLF, 72PR50KLF, 72PMR50KLF, 82PR50KLF) provide functionally equivalent substitution with active status and RoHS compliance. These parts differ in physical dimensions and packaging configurations. The 25PR50KLF maintains the closest dimensional profile to the original part. The 72-series parts feature larger form factors (0.375" square or 0.250" round), while the 82PR50KLF uses a round configuration.

Component selection should account for printed circuit board layout constraints and available mounting space, as physical dimensions vary among substitutes despite electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-503LF directly replace the PVC6A503A01B00?

A: Yes. Both parts maintain identical electrical specifications: 50 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, and PC pin termination. The primary difference is resistive material (cermet versus ceramic) and compliance status. The 3362P-1-503LF is actively produced and ROHS3 compliant.

Q: What is the difference between the TT Electronics/BI substitute options?

A: All TT Electronics/BI substitutes (25PR50KLF, 72PR50KLF, 72PMR50KLF, 82PR50KLF) are electrically equivalent. Differences exist in physical dimensions and packaging. The 25PR50KLF has a square 0.270" face, the 72-series parts feature a larger 0.375" square form factor, and the 82PR50KLF uses a 0.250" round configuration. Selection depends on available PCB space and mounting requirements.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The original PVC6A503A01B00 is supplied in standard packaging. The 3362P-1-503LF is packaged in tubes (65,900 units available). The TT Electronics/BI parts are supplied in bulk packaging. Packaging format may affect procurement lead times and minimum order quantities.

Q: Does the change from ceramic to cermet resistive material affect performance?

A: Both ceramic and cermet materials meet the specified electrical parameters for this application. Cermet construction in the substitute parts provides improved stability and is standard in current production trimmer potentiometers.

Q: Which substitute offers the best compliance profile?

A: The 3362P-1-503LF and all TT Electronics/BI substitutes (72PR50KLF, 72PMR50KLF, 82PR50KLF) are ROHS3 compliant. The 25PR50KLF is RoHS compliant. All substitutes are REACH unaffected or REACH affected with equivalent regulatory standing. The original PVC6A503A01B00 is RoHS non-compliant and obsolete.
