Bourns 3339P-1-101 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3339P-1-101 is a 100 Ohm, 0.5W through-hole trimmer potentiometer with cermet resistive material, designed for PC pin termination and top adjustment. This sealed Trimpot® 3339 series component is currently active in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative compliance certifications are required.

Substitute Part Grouping Explanation

Substitution eligibility for the 3339P-1-101 is determined by strict equivalence across the following critical parameters: resistance value (100 Ohms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (4), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical size compatibility (round package approximately 0.300" diameter).

Two substitute parts meet these criteria:

3339P-1-101LF - Direct equivalent within the same Trimpot® 3339 series, identical electrical and mechanical specifications, with RoHS3 compliance certification (versus non-compliant status of the primary part).

PV12P101A01B00 - Alternative from the Bourns PV12 series, matching all electrical parameters and mechanical form factor with minor dimensional tolerance (0.299" vs 0.300" diameter), RoHS3 compliant, with different REACH and MSL classifications.

Parameter Comparison

Engineering Selection Recommendations

3339P-1-101LF is the primary substitute for the 3339P-1-101. Both parts are from the same sealed Trimpot® 3339 series with identical electrical and mechanical specifications. The 3339P-1-101LF carries RoHS3 compliance certification, whereas the original part is RoHS non-compliant. Selection of the 3339P-1-101LF is appropriate for applications requiring RoHS compliance or when the original part is unavailable.

PV12P101A01B00 is an alternative substitute from the Bourns PV12 series. All electrical parameters match the primary part. The physical diameter differs by 0.001" (0.299" versus 0.300"), which falls within standard manufacturing tolerances for round potentiometer packages. This part carries RoHS3 compliance and REACH Unaffected status. Selection of PV12P101A01B00 is appropriate when cross-series compatibility is acceptable and enhanced regulatory compliance is required.

All three parts share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications, supporting consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can 3339P-1-101LF be used as a direct replacement for 3339P-1-101?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and package size. The primary difference is RoHS3 compliance certification on the 3339P-1-101LF.

Q: What is the significance of the 0.001" diameter difference between 3339P-1-101 and PV12P101A01B00?

A: The diameter difference (0.300" versus 0.299") is within standard manufacturing tolerances for round potentiometer packages and does not affect electrical performance or mechanical fit in standard through-hole PCB applications.

Q: Are there any compliance differences between the three parts?

A: Yes. The 3339P-1-101 is RoHS non-compliant and REACH Affected. Both 3339P-1-101LF and PV12P101A01B00 are RoHS3 compliant. Additionally, PV12P101A01B00 is REACH Unaffected, whereas the other two parts are REACH Affected.

Q: Which substitute should be selected for new designs?

A: Selection depends on regulatory requirements and series preference. For RoHS compliance within the same Trimpot® 3339 series, use 3339P-1-101LF. For cross-series compatibility with enhanced REACH status, use PV12P101A01B00. Both are electrically equivalent.

Q: Do all three parts have the same MSL rating?

A: No. The 3339P-1-101 and 3339P-1-101LF both have MSL 1 (Unlimited). The PV12P101A01B00 has MSL Not Applicable, indicating different moisture sensitivity classification.

Q: Are packaging and inventory considerations the same across all three parts?

A: All three parts are supplied in Tube packaging. Inventory levels vary: 3339P-1-101 (892 pcs), 3339P-1-101LF (1110 pcs), and PV12P101A01B00 (1239 pcs). Availability should be confirmed with the supplier for current procurement.
