PVC6Q503A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6Q503A01B00 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 identification of suitable substitutes necessary for ongoing production and maintenance applications. Equivalent parts must maintain the same electrical specifications, mechanical form factor compatibility, and termination style to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical 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). Parts meeting these criteria are classified as direct substitutes regardless of resistive material composition (ceramic or cermet) or dimensional variations within acceptable mechanical tolerances. The identified substitutes are:

Direct Substitute: 3362M-1-503LF (Bourns Inc., Trimpot® 3362 series, cermet material, active status)

Similar Substitute: RJ-6X503 (Nidec Components Corporation, RJ-6 series, cermet material, active status)

Parameter Comparison

Engineering Selection Recommendations

The 3362M-1-503LF is the primary substitute for the PVC6Q503A01B00. Both parts are manufactured by Bourns Inc., share identical electrical specifications, and feature PC pin termination compatible with existing PCB layouts. The 3362M-1-503LF carries active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original part. The cermet resistive material in the 3362M-1-503LF provides equivalent performance within the specified tolerance and temperature coefficient ranges.

The RJ-6X503 is a secondary substitute manufactured by Nidec Components Corporation. It maintains all critical electrical parameters and mechanical compatibility. The RJ-6X503 is active and ROHS3 compliant. Minor dimensional differences (7.00mm x 6.60mm versus 8.00mm x 6.90mm) fall within acceptable mechanical tolerances for through-hole applications and do not affect electrical performance or PCB mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3362M-1-503LF directly replace the PVC6Q503A01B00 in existing designs?

A: Yes. Both parts share identical electrical specifications (50 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, side adjustment) and PC pin termination. Minor dimensional differences (6.99mm x 6.60mm versus 8.00mm x 6.90mm) do not affect PCB mounting or electrical performance.

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

A: Both ceramic and cermet materials meet the specified tolerance (±10%) and temperature coefficient (±100ppm/°C) for this application. Cermet material, used in the 3362M-1-503LF and RJ-6X503, offers improved stability and is commonly used in sealed trimmer designs.

Q: Is the RJ-6X503 a suitable alternative if the 3362M-1-503LF is unavailable?

A: Yes. The RJ-6X503 meets all critical electrical and mechanical parameters. It is manufactured by Nidec Components Corporation, carries active product status, and is ROHS3 compliant. Dimensional differences are within acceptable tolerances for through-hole applications.

Q: What packaging options are available for these substitutes?

A: The 3362M-1-503LF is supplied in tube packaging. The RJ-6X503 is supplied in bulk packaging. Packaging selection depends on production volume and handling requirements.

Q: Are both substitutes RoHS compliant?

A: Yes. Both the 3362M-1-503LF and RJ-6X503 are ROHS3 compliant, addressing the non-compliance status of the obsolete PVC6Q503A01B00.
