3296W-1-503ALF Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The 3296W-1-503ALF is a 50 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. as part of the Trimpot® 3296 sealed series. This component is an active product with ROHS3 compliance and is designed for applications requiring precision resistive adjustment in compact form factors. Substitute parts become necessary when the original packaging format (Cut Tape) is unavailable, when alternative series options are preferred for supply chain optimization, or when inventory constraints require sourcing from equivalent product lines that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3296W-1-503ALF is determined by strict equivalence across the following critical parameters: resistance value (50 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (25), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All substitute parts must maintain identical electrical performance characteristics and mechanical compatibility with the original design. Packaging format differences (Cut Tape versus Tube) do not affect functional substitution but may impact procurement and assembly workflows. Series designation changes (Trimpot® 3296 to PV36) are permissible when all electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3296W-1-503ALF, PV36W503C01B00, and PV36Y503C01B00—are active products from Bourns Inc. with identical electrical specifications and ROHS3 compliance. Selection between these parts should be based on packaging requirements and availability. The 3296W-1-503ALF is supplied in Cut Tape format, suitable for automated pick-and-place assembly. The PV36W503C01B00 and PV36Y503C01B00 are supplied in Tube packaging, appropriate for manual assembly or alternative procurement workflows. Dimensional variations between the Trimpot® 3296 series (9.53mm x 4.83mm) and PV36 series (9.60mm x 5.00mm) are minimal and do not affect PCB layout compatibility for standard through-hole applications. All parts maintain REACH compliance and equivalent regulatory status.

Frequently Asked Questions (FAQ)

Q: Can PV36W503C01B00 or PV36Y503C01B00 be used as direct replacements for 3296W-1-503ALF?

A: Yes. All three parts share identical electrical parameters: 50 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, top adjustment type, cermet resistive material, through-hole mounting, and PC pin termination. Functional substitution is complete.

Q: What is the difference between PV36W503C01B00 and PV36Y503C01B00?

A: Both parts are electrically and mechanically identical. The difference lies in the base product number designation (PV36W versus PV36Y), which may reflect internal Bourns manufacturing or series classification. No functional distinction exists for circuit design or performance.

Q: Are there dimensional compatibility concerns when substituting between series?

A: Dimensional differences are negligible. The 3296W-1-503ALF measures 9.53mm x 4.83mm, while PV36 series parts measure 9.60mm x 5.00mm. These variations fall within standard PCB layout tolerances for through-hole components and do not require design modifications.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) and Tube packaging formats are logistics and assembly considerations only. Electrical and mechanical specifications remain identical regardless of packaging.

Q: Are all parts compliant with current regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH affected, meeting current environmental and regulatory standards for electronic components.
