PVC6G503A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6G503A01B00 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 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 (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 acceptable tolerance for PCB footprint compatibility. The identified substitutes meet all mandatory electrical and mechanical criteria.

Parameter Comparison

Engineering Selection Recommendations

Both 3362W-1-503LF and RJ-6X503 are qualified substitutes for the obsolete PVC6G503A01B00 based on electrical parameter equivalence. The 3362W-1-503LF offers ROHS3 compliance and active product status from Bourns Inc., the original manufacturer, ensuring design continuity and supply chain reliability. The RJ-6X503 from Nidec Components Corporation provides an alternative source with ROHS3 compliance and active status, reducing single-source dependency. Both substitutes employ cermet resistive material, which provides improved stability characteristics compared to the ceramic material of the original part. Physical dimensions of both substitutes are slightly smaller than the original, requiring verification of PCB layout compatibility before implementation. Selection between substitutes should prioritize supply availability, cost considerations, and existing supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the 3362W-1-503LF and RJ-6X503 be used interchangeably with the PVC6G503A01B00?

A: Both substitutes meet all mandatory electrical specifications: 50 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, through-hole mounting, and PC pin termination. Physical dimensions differ slightly; PCB footprint compatibility must be confirmed before substitution.

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

A: Both ceramic and cermet materials satisfy the specified electrical performance parameters for this application. Cermet material, used in both substitutes, typically offers improved temperature stability and frequency response characteristics.

Q: Why is the original PVC6G503A01B00 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Bourns Inc. Active substitutes ensure continued availability and access to current manufacturing processes and compliance certifications.

Q: Are there compliance differences between the substitutes?

A: The 3362W-1-503LF is REACH Affected, while the RJ-6X503 is REACH Unaffected. Both are ROHS3 compliant. Regulatory requirements for your application determine which compliance profile is appropriate.

Q: Do the smaller dimensions of the substitutes affect PCB design?

A: The 3362W-1-503LF and RJ-6X503 have slightly reduced face dimensions compared to the original part. Verify that existing PCB footprints accommodate these dimensional variations before implementation.
