Bourns 3386G-1-501 Equivalent & Substitute Parts

Part Overview

The Bourns 3386G-1-501 is a 500 Ohm, 0.5W through-hole trimmer potentiometer with PC pin termination, top adjustment, and cermet resistive material. This component is classified as Active product status. Alternative equivalent parts may be required due to packaging availability, RoHS compliance requirements, or specific form factor constraints in design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386G-1-501 is determined by matching the following critical parameters: 500 Ohms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, top adjustment type, cermet resistive material, through-hole mounting, and PC pin termination. All listed substitute parts meet these electrical and functional specifications. Physical form factor differences (size and shape) are noted but do not prevent functional substitution in applications where PCB layout permits component repositioning.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (25PR500LF, 72PR500LF, 82PR500LF) are Active status components manufactured by TT Electronics/BI and provide electrical equivalence to the 3386G-1-501. Selection between substitutes depends on specific design constraints:

The 72PR500LF maintains identical physical dimensions (0.375" x 0.375" square) to the original part, making it the most direct form-factor match for existing PCB layouts. The 25PR500LF offers a smaller footprint (0.270" x 0.270" square) and is available in tube packaging. The 82PR500LF provides a round form factor (0.250" diameter) and bulk packaging option.

For applications subject to RoHS or REACH compliance requirements, all three substitute parts offer superior regulatory status compared to the original 3386G-1-501, which is RoHS non-compliant and REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can the 25PR500LF replace the 3386G-1-501 in existing designs? A: The 25PR500LF is electrically equivalent but has a smaller physical footprint (0.270" x 0.270" versus 0.375" x 0.375"). PCB layout verification is required to confirm mounting hole spacing compatibility.

Q: What is the primary difference between the 72PR500LF and 82PR500LF? A: Both are electrically identical 500 Ohm, 0.5W trimmer potentiometers. The 72PR500LF has a square form factor (0.375" x 0.375"), while the 82PR500LF has a round form factor (0.250" diameter). Form factor selection depends on available PCB space and mounting hole configuration.

Q: Are all substitute parts suitable for RoHS-compliant applications? A: Yes. The 25PR500LF, 72PR500LF, and 82PR500LF are all RoHS Compliant or ROHS3 Compliant, whereas the original 3386G-1-501 is RoHS non-compliant.

Q: Does packaging type affect electrical performance? A: No. Tube and Bulk packaging are handling and shipping formats only. Electrical specifications and performance are identical regardless of packaging type.

Q: Which substitute offers the closest mechanical compatibility with the original 3386G-1-501? A: The 72PR500LF matches the original part's square form factor and dimensions (0.375" x 0.375"), providing the highest mechanical compatibility for direct PCB layout substitution.
