Bourns 3296X-1-503RLF Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3296X-1-503RLF is a 50 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This component is part of the Trimpot® 3296 sealed series and maintains active product status. Substitute parts become necessary when tape & reel packaging is unavailable or when alternative series configurations are required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3296X-1-503RLF 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 (25), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). Both substitute parts—PV36X503C01B00 and PV36Z503C01B00—meet all these criteria. The primary difference between the main part and substitutes is packaging format (tape & reel versus tube) and minor dimensional variations within acceptable mechanical tolerances. Both substitute parts are manufactured by Bourns Inc. and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance. Selection between the 3296X-1-503RLF and its substitutes depends on packaging requirements and dimensional tolerance acceptance. The 3296X-1-503RLF is supplied in tape & reel format, suitable for automated assembly processes. The PV36X503C01B00 and PV36Z503C01B00 are supplied in tube packaging, appropriate for manual assembly or lower-volume applications. Dimensional differences are minimal and fall within standard mechanical tolerances for through-hole trimmer potentiometers. All parts carry identical electrical specifications and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can PV36X503C01B00 or PV36Z503C01B00 be used as direct replacements for 3296X-1-503RLF?

A: Yes. Both parts are electrically and functionally equivalent. They share identical resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style. The primary difference is packaging format (tube versus tape & reel) and minor face dimensions within acceptable mechanical tolerances.

Q: What is the difference between PV36X503C01B00 and PV36Z503C01B00?

A: Both parts are identical in electrical specifications and mechanical dimensions. The difference lies in the base product number designation (PV36X versus PV36Z), which reflects internal Bourns product line categorization. Both are supplied in tube packaging and maintain equivalent performance.

Q: Are there packaging compatibility considerations?

A: Yes. The 3296X-1-503RLF is supplied in tape & reel format for automated pick-and-place assembly. The PV36X503C01B00 and PV36Z503C01B00 are supplied in tube packaging, requiring manual handling or alternative assembly processes. Verify your assembly equipment compatibility before substitution.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant, REACH affected, and carry identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires equivalence in resistance (50 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (25), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).
