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

Part Overview

The Bourns 3262P-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 applications requiring precision variable resistance in compact rectangular form factor (0.250" x 0.185" face). The part is currently active in production. Substitute parts are necessary when the primary part is unavailable, when RoHS compliance is required, or when alternative mechanical configurations better suit specific PCB layout constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3262P-1-502 is determined by matching the following critical parameters: 5 kOhms resistance, 0.25W power rating, 12-turn adjustment, side adjustment mechanism, cermet resistive material, through-hole mounting, and PC pin termination. All listed substitute parts meet these core electrical and mechanical requirements.

The substitute parts are grouped as follows:

Direct Manufacturer Equivalent (Bourns): 3262P-1-502LF differs only in RoHS compliance status (ROHS3 Compliant vs. non-compliant) and remains within the same Trimpot® 3262 series with identical electrical specifications and form factor.

Cross-Manufacturer Substitutes (TT Electronics/BI): 64PR5KLF and 64XR5KLF are functionally equivalent alternatives from a different manufacturer. Both maintain all critical electrical parameters and through-hole PC pin configuration. Mechanical form factors vary slightly: 64PR5KLF uses a square face (0.250" x 0.250"), while 64XR5KLF uses a rectangular face (0.250" x 0.165").

Parameter Comparison

Engineering Selection Recommendations

For RoHS-compliant applications: Select 3262P-1-502LF (Bourns ROHS3 Compliant) or either TT Electronics/BI option (64PR5KLF or 64XR5KLF, both RoHS Compliant). The 3262P-1-502 original part is not suitable for RoHS-regulated designs.

For REACH-unaffected sourcing: Choose 64PR5KLF or 64XR5KLF from TT Electronics/BI. Both parts are REACH Unaffected, whereas the Bourns options (3262P-1-502 and 3262P-1-502LF) are REACH Affected.

For identical form factor retention: Use 3262P-1-502LF to maintain the original 0.250" x 0.185" rectangular face dimension. This ensures no PCB layout modification is required.

For alternative mechanical configurations: 64PR5KLF provides a square 0.250" x 0.250" face, while 64XR5KLF offers a narrower 0.250" x 0.165" rectangular face. Selection depends on available PCB space and mounting constraints.

For maximum inventory availability: 64XR5KLF has the highest stock level (8,684 pcs), followed by 64PR5KLF (1,796 pcs) and 3262P-1-502LF (936 pcs).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The only difference is RoHS compliance status. 3262P-1-502LF is ROHS3 Compliant, while 3262P-1-502 is non-compliant. If RoHS compliance is not required, either part functions identically in the circuit.

Q: What is the primary difference between the Bourns and TT Electronics/BI options?

A: All parts share identical electrical specifications (5 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C, 12-turn cermet). The differences are manufacturer identity, form factor dimensions, and regulatory compliance status. Bourns parts are REACH Affected; TT Electronics/BI parts are REACH Unaffected.

Q: Will 64PR5KLF fit in the same PCB footprint as 3262P-1-502?

A: No. 64PR5KLF has a square 0.250" x 0.250" face, while 3262P-1-502 has a rectangular 0.250" x 0.185" face. PCB layout modification is required. 64XR5KLF (0.250" x 0.165") is closer in profile but still differs in height.

Q: Are all substitute parts rated for the same power dissipation?

A: Yes. All parts are rated at 0.25W (1/4W) and maintain identical temperature coefficient performance (±100ppm/°C).

Q: Which substitute part should be selected for new designs?

A: For new designs, prioritize RoHS-compliant parts: 3262P-1-502LF (Bourns) for form factor consistency, or 64PR5KLF/64XR5KLF (TT Electronics/BI) if REACH compliance is also required. All three are active production parts.

Q: Do the substitute parts have different moisture sensitivity levels?

A: Yes. The original 3262P-1-502 and 3262P-1-502LF have MSL ratings listed as Not Applicable. The TT Electronics/BI parts (64PR5KLF and 64XR5KLF) are rated MSL 1 (Unlimited), indicating superior moisture resistance for storage and handling.
