Bourns 3296P-1-203 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3296P-1-203 is a 20 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination, designed for side adjustment applications. This sealed Trimpot® 3296 series component features cermet resistive material and 25-turn adjustment capability. The part is currently active in production. Substitute parts are identified when the original part becomes unavailable, when RoHS3 compliance is required, or when alternative series options within equivalent electrical specifications are needed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3296P-1-203 are qualified based on matching the following critical electrical and mechanical parameters:

• Resistance value: 20 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
• Termination style: PC Pins

Two substitute parts meet these criteria: the 3296P-1-203LF (direct variant with RoHS3 compliance) and the PV36P203C01B00 (alternative series with equivalent electrical performance and RoHS3 compliance). Both maintain functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 3296P-1-203LF is the primary direct substitute, offering identical electrical specifications and mechanical form factor while providing ROHS3 compliance. This variant is recommended when RoHS3 certification is required or when the original part number becomes unavailable.

The PV36P203C01B00 represents an alternative series option with equivalent electrical performance and ROHS3 compliance. Face dimensions differ slightly (0.378" x 0.197" versus 0.375" x 0.190"), which may require verification for space-constrained PCB layouts. This part is suitable when the 3296 series is unavailable and dimensional tolerance of approximately 0.003" to 0.007" is acceptable.

All three parts share identical electrical specifications, temperature performance, and termination characteristics. Selection between them depends on availability, RoHS compliance requirements, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3296P-1-203LF be used as a direct replacement for the 3296P-1-203?

A: Yes. The 3296P-1-203LF maintains identical electrical specifications, tolerance, temperature coefficient, number of turns, and physical form factor. The primary difference is ROHS3 compliance status.

Q: What is the difference between the 3296P-1-203 and 3296P-1-203LF?

A: Both parts are from the Trimpot® 3296 sealed series with identical electrical and mechanical parameters. The 3296P-1-203LF carries ROHS3 compliance certification, while the 3296P-1-203 does not.

Q: Can the PV36P203C01B00 replace the 3296P-1-203?

A: The PV36P203C01B00 provides equivalent electrical performance and is mechanically compatible for most applications. However, face dimensions differ by approximately 0.003" to 0.007" in each axis. Verify PCB layout clearances before substitution.

Q: Are all three parts from the same manufacturer?

A: Yes. All three parts are manufactured by Bourns Inc., ensuring consistent quality and performance standards.

Q: What packaging is used for these parts?

A: All three parts are supplied in tube packaging.

Q: Do these parts have moisture sensitivity requirements?

A: No. Moisture Sensitivity Level (MSL) is not applicable for any of these trimmer potentiometers.
