Bourns 3262X-1-502 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3262X-1-502 is a 5 kOhm, 0.25W through-hole trimmer potentiometer with PC pin termination and side adjustment. This sealed Trimpot® 3262 series component is designed for precision adjustment applications requiring cermet resistive elements and 12-turn resolution. The part is currently active in production. Substitute parts may be required due to inventory availability, RoHS compliance requirements, or specific application constraints such as package dimensions or regulatory status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262X-1-502 is determined by strict equivalence across the following electrical and mechanical parameters: resistance value (5 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

The substitute parts identified fall into two categories:

Direct Manufacturer Equivalent: 3262X-1-502LF maintains identical electrical specifications and series designation (Trimpot® 3262 - Sealed) with the same package footprint. The primary distinction is RoHS compliance status.

Cross-Manufacturer Alternatives: 64PR5KLF and 64XR5KLF are manufactured by TT Electronics/BI and meet all core electrical parameters. These parts differ in package dimensions and regulatory compliance profiles, requiring physical verification for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

3262X-1-502LF is the primary substitute when RoHS3 compliance is required. This part maintains identical electrical performance and package footprint while achieving enhanced regulatory status. It is suitable for direct replacement in new designs or existing assemblies where RoHS compliance is mandatory.

64PR5KLF and 64XR5KLF are viable alternatives when cross-manufacturer sourcing is acceptable. Both parts achieve RoHS compliance and REACH unaffected status. Selection between these two TT Electronics/BI options depends on PCB layout constraints: 64PR5KLF has a square face (0.250" x 0.250"), while 64XR5KLF has a rectangular face (0.250" x 0.165") closer to the original 3262X-1-502 dimensions.

The original 3262X-1-502 remains suitable for applications where RoHS non-compliance is acceptable and REACH affected status does not present regulatory barriers.

Frequently Asked Questions (FAQ)

Q: Can 3262X-1-502LF be used as a direct drop-in replacement for 3262X-1-502?

A: Yes. Both parts share identical electrical specifications (5 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C), the same 12-turn side adjustment mechanism, cermet resistive element, and matching package footprint (0.250" x 0.170" face). The primary difference is RoHS3 compliance status of the LF variant.

Q: What are the dimensional differences between the Bourns and TT Electronics/BI alternatives?

A: The original 3262X-1-502 and 3262X-1-502LF both measure 0.250" x 0.170" (6.35mm x 4.32mm) on the face. The 64PR5KLF has a square footprint of 0.250" x 0.250" (6.35mm x 6.35mm), while the 64XR5KLF measures 0.250" x 0.165" (6.35mm x 4.19mm). PCB layout verification is required when substituting with 64PR5KLF due to its larger square profile.

Q: Are there compliance differences between these parts?

A: Yes. The 3262X-1-502 is RoHS non-compliant and REACH affected. The 3262X-1-502LF achieves RoHS3 compliance but remains REACH affected. Both 64PR5KLF and 64XR5KLF are RoHS compliant and REACH unaffected, making them suitable for applications with stricter regulatory requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: No. The Bourns 3262X series parts (3262X-1-502 and 3262X-1-502LF) list moisture sensitivity as not applicable. The TT Electronics/BI 64 series parts (64PR5KLF and 64XR5KLF) are rated MSL 1 (unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which substitute offers the best inventory availability?

A: The 3262X-1-502LF has the highest inventory at 10,200 pieces. The 64XR5KLF follows with 8,684 pieces. The original 3262X-1-502 has 1,065 pieces, and 64PR5KLF has 1,796 pieces in stock.
