Equivalent & Substitute Parts for 3362H-1-102

Part Overview

The Bourns 3362H-1-102 is a 1 kOhms, 0.5W through-hole trimmer potentiometer with cermet resistive material, top adjustment, and PC pin termination. This sealed Trimpot® 3362 series component is actively manufactured and widely used in precision circuit tuning applications. Alternative equivalent parts may be required due to inventory availability, compliance requirements, or specific mechanical constraints in board layout and assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3362H-1-102 is determined by strict equivalence across the following critical parameters: resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All substitute parts listed maintain these electrical and functional specifications. Mechanical dimensions vary across substitute groups, which may affect board layout compatibility but do not alter electrical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The 3362H-1-102LF is the direct equivalent of the 3362H-1-102, maintaining identical electrical specifications and mechanical dimensions while providing ROHS3 compliance. This part is the preferred substitute when RoHS compliance is required for new designs or manufacturing processes.

The 25PR1KLF offers electrical equivalence with a slightly smaller square footprint (0.270" x 0.270") and RoHS compliance. This part is suitable for applications where board space is constrained and the reduced dimensions do not conflict with layout requirements.

The 72PR1KLF and 72PMR1KLF provide electrical equivalence with a larger square footprint (0.375" x 0.375") and ROHS3 compliance. These parts accommodate applications requiring larger adjustment knob access or where the increased size does not present layout constraints.

The 82PR1KLF provides electrical equivalence with a circular footprint (0.250" diameter) and ROHS3 compliance. This part is applicable to designs where circular form factor is preferred or required for mechanical integration.

All substitute parts maintain active product status and are manufactured to the same electrical specifications. Selection should be based on mechanical fit within the printed circuit board layout and compliance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can 3362H-1-102LF be used as a direct replacement for 3362H-1-102?

A: Yes. The 3362H-1-102LF is electrically and mechanically identical to the 3362H-1-102, with the addition of ROHS3 compliance. Both parts share the same resistance value, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions.

Q: What is the primary difference between the Bourns and TT Electronics substitute parts?

A: The Bourns 3362H-1-102LF maintains the original rectangular footprint (0.275" x 0.260"). The TT Electronics parts offer alternative form factors: 25PR1KLF uses a smaller square footprint (0.270" x 0.270"), 72PR1KLF and 72PMR1KLF use a larger square footprint (0.375" x 0.375"), and 82PR1KLF uses a circular footprint (0.250" diameter). All maintain identical electrical performance.

Q: Are there compliance differences between substitute parts?

A: The original 3362H-1-102 is RoHS non-compliant. The 3362H-1-102LF, 72PR1KLF, 72PMR1KLF, and 82PR1KLF are ROHS3 compliant. The 25PR1KLF is RoHS compliant. Selection depends on the compliance requirements of the target application and manufacturing process.

Q: Can I use a larger footprint part in a design that specifies the original dimensions?

A: Larger footprint parts (72PR1KLF, 72PMR1KLF) require verification that the printed circuit board layout accommodates the increased dimensions. The 0.375" x 0.375" footprint is significantly larger than the original 0.275" x 0.260" rectangular or the 0.250" circular form factor. Board layout compatibility must be confirmed before substitution.

Q: What is the difference between 72PR1KLF and 72PMR1KLF?

A: Both parts share identical electrical specifications and the same square footprint (0.375" x 0.375"). The primary difference is packaging: 72PR1KLF is supplied in bulk packaging, while 72PMR1KLF is also supplied in bulk packaging. Both are ROHS3 compliant and maintain the same electrical performance.

Q: Are all substitute parts actively manufactured?

A: Yes. All listed substitute parts maintain active product status with Bourns Inc. and TT Electronics/BI, ensuring continued availability and consistent manufacturing quality.
