Bourns 3339H-1-104 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3339H-1-104 is a 100 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination, top adjustment, and cermet resistive material. This sealed Trimpot® 3339 series component is actively produced and stocked at 946 units. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical form factor, and termination compatibility to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (100 kOhms), 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.

The 3339H-1-104 has two identified substitutes:

Direct Equivalent (3339H-1-104LF): Identical electrical and mechanical specifications within the same Trimpot® 3339 series. Differs only in RoHS compliance status (ROHS3 compliant vs. non-compliant).

Cross-Series Substitute (PV12P104A01B00): Bourns PV12 series trimmer with matching electrical parameters and equivalent physical dimensions (0.299" vs. 0.300" diameter). Differs in series designation, RoHS compliance, and REACH status.

Parameter Comparison

Engineering Selection Recommendations

3339H-1-104LF is the primary direct substitute. It maintains identical electrical and mechanical specifications within the same sealed Trimpot® 3339 series and offers improved compliance status (ROHS3 compliant). Selection is appropriate for applications requiring RoHS3 compliance or when the original part is unavailable.

PV12P104A01B00 is a cross-series alternative from the Bourns PV12 family. Physical dimensions are equivalent within manufacturing tolerance (0.299" vs. 0.300" diameter). This substitute is suitable for applications where REACH compliance is required or when Trimpot® 3339 series parts are unavailable. Verify mechanical fit in the PCB layout due to minor dimensional variation.

Both substitutes are actively produced and maintain full inventory availability. Selection between them depends on regulatory compliance requirements and supply chain constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 3339H-1-104LF be used as a direct replacement for 3339H-1-104?

A: Yes. Both parts are identical in electrical specifications (100 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C) and mechanical form factor (through-hole PC pins, top adjustment, cermet material, 4-turn). The primary difference is RoHS compliance status. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the 3339H-1-104 and PV12P104A01B00?

A: Both parts share identical electrical specifications and adjustment characteristics. The PV12P104A01B00 belongs to a different Bourns series (PV12 vs. Trimpot® 3339) and has a marginally smaller diameter (0.299" vs. 0.300"). Physical fit must be verified in the specific PCB layout. The PV12 series offers REACH compliance advantage.

Q: Are there packaging differences between these substitutes?

A: All three parts are supplied in tube packaging. No tape-and-reel or alternative packaging options are specified in the provided data.

Q: Which substitute should be selected for RoHS-compliant applications?

A: Both 3339H-1-104LF and PV12P104A01B00 are ROHS3 compliant. The 3339H-1-104LF is recommended as the primary choice due to identical series and form factor. The PV12P104A01B00 is an alternative if 3339H-1-104LF is unavailable.

Q: Is the 0.01" diameter difference between 3339H-1-104 and PV12P104A01B00 significant?

A: The 0.01" (0.254mm) difference is within typical PCB hole tolerance but must be verified against the specific board design. Confirm that the PV12P104A01B00 mounting holes align with the PCB layout before implementation.
