Bourns 3296P-1-504 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3296P-1-504 is a 500 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment. This sealed Trimpot® 3296 series component is designed for applications requiring precision resistance adjustment in compact form factors. The part is currently active in production with 2300 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required, particularly when RoHS compliance or alternative series options are necessary for procurement or design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3296P-1-504 are identified based on matching the following critical parameters: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, side adjustment type, cermet resistive material, through-hole mounting, and PC pin termination.

Two substitute relationships are established:

Direct Substitute (Same Series): The 3296P-1-504LF maintains identical electrical specifications and mechanical form factor while offering improved RoHS3 compliance status compared to the original part.

Cross-Series Substitute (Alternative Series): The PV36P504C01B00 from the PV36 series provides equivalent electrical performance and mechanical compatibility with minor dimensional variation (9.60mm x 5.00mm versus 9.53mm x 4.83mm face dimensions), while also meeting RoHS3 compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: The 3296P-1-504LF is the preferred direct substitute, maintaining identical specifications and form factor while meeting ROHS3 compliance. This part is recommended when regulatory requirements mandate RoHS3 certification.

For Cross-Series Compatibility: The PV36P504C01B00 provides equivalent electrical performance and is suitable when alternative series sourcing is required. The minor dimensional variation (0.03" and 0.007" increase in face dimensions) must be evaluated against PCB layout constraints. This part also meets ROHS3 compliance requirements.

For Original Specification Matching: The 3296P-1-504 remains the primary selection when RoHS non-compliant status is acceptable and original series continuity is required.

All three parts share identical electrical characteristics, mechanical mounting compatibility, and termination style, ensuring functional interchangeability within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 3296P-1-504LF be used as a direct replacement for the 3296P-1-504?

A: Yes. The 3296P-1-504LF is a direct substitute with identical electrical specifications (500 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C), mechanical dimensions (0.375" x 0.190" face), and mounting configuration. The primary difference is RoHS3 compliance status.

Q: What is the dimensional difference between the 3296P-1-504 and PV36P504C01B00?

A: The PV36P504C01B00 has a slightly larger face dimension of 0.378" x 0.197" (9.60mm x 5.00mm) compared to 0.375" x 0.190" (9.53mm x 4.83mm) for the 3296P-1-504. This 0.03" and 0.007" increase must be verified against PCB layout and mounting hole spacing.

Q: Are all three parts electrically equivalent?

A: Yes. All three parts provide 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, and cermet resistive material. They are electrically interchangeable.

Q: Which substitute should be selected for new designs?

A: Selection depends on compliance requirements. For RoHS3 compliance, either the 3296P-1-504LF (same series) or PV36P504C01B00 (alternative series) are suitable. Verify dimensional constraints for the PV36P504C01B00 due to minor face dimension variation.

Q: What is the packaging format for these parts?

A: All three parts are supplied in tube packaging.
