PVC6E503A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6E503A01B00 is a 50 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, side adjustment, and PC pin termination. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6E503A01B00 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 (1.0), adjustment type (side adjustment), mounting type (through hole), and termination style (PC pins). Resistive material variation between ceramic and cermet is permitted within this product category, as both materials satisfy the specified electrical performance requirements. Physical dimensions must remain within the rectangular form factor classification. All substitute parts must maintain compatibility with PC pin through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The 3362S-1-503LF is the primary substitute for the PVC6E503A01B00. Both parts are manufactured by Bourns Inc., ensuring design continuity and supply chain consistency. The 3362S-1-503LF maintains all required electrical specifications and offers active product status with ROHS3 compliance. The cermet resistive material provides equivalent performance to the ceramic material in the original part. Physical dimensions are slightly reduced but remain compatible with standard through-hole PCB layouts designed for 50 kOhm trimmer potentiometers.

The RJ-6X503 manufactured by Nidec Components Corporation is an alternative substitute that meets all electrical and mechanical requirements. This part offers active product status and ROHS3 compliance. Physical dimensions are nearly identical to the 3362S-1-503LF, with minimal variation in the mounting face. Selection between the two substitutes depends on supply availability, packaging requirements (tube versus bulk), and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the 3362S-1-503LF directly replace the PVC6E503A01B00 on existing PCBs?

A: Yes. Both parts share identical electrical specifications (50 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and PC pin through-hole termination. Physical dimensions are slightly smaller but compatible with standard through-hole layouts. No circuit modifications are required.

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

A: Both materials meet the specified electrical performance requirements for this application. Cermet material, used in the 3362S-1-503LF and RJ-6X503, offers improved stability and reliability in sealed designs. The original PVC6E503A01B00 uses ceramic material. Selection between materials does not affect circuit functionality when electrical specifications are identical.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 3362S-1-503LF is supplied in tube packaging, while the RJ-6X503 is supplied in bulk packaging. Tube packaging is standard for active production parts and facilitates automated assembly processes. Bulk packaging may require manual handling and sorting.

Q: Does the slightly smaller physical size of the substitutes affect PCB layout compatibility?

A: No. The substitute parts maintain rectangular form factors with dimensions within acceptable tolerances for through-hole trimmer potentiometer footprints. PCBs designed for the PVC6E503A01B00 will accommodate the 3362S-1-503LF and RJ-6X503 without layout modifications.

Q: What compliance certifications should be considered when selecting a substitute?

A: The PVC6E503A01B00 is RoHS non-compliant. Both substitute parts (3362S-1-503LF and RJ-6X503) are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and production runs. The 3362S-1-503LF is REACH affected, while the RJ-6X503 is REACH unaffected.

Q: Why is the PVC6E503A01B00 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. Bourns Inc. has transitioned to the 3362S series (Trimpot® 3362 - Sealed) as the current standard offering, which provides improved compliance certifications and sealed design benefits while maintaining electrical equivalence.
