Substitute Part Grouping Explanation

Substitute parts for the 3262W-1-502 are grouped based on electrical parameter equivalence and mechanical compatibility. All identified substitutes maintain identical resistance (5 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

The primary substitution criterion is dimensional compatibility. The main part specifies a face dimension of 0.250" x 0.170" (6.35mm x 4.32mm). Substitute parts from TT Electronics/BI Technologies (64WR5KLF and 64YR5KLF) feature a face dimension of 0.250" x 0.165" (6.35mm x 4.19mm), representing a 0.005" (0.13mm) reduction in the secondary axis. This dimensional variance remains within typical PCB layout tolerances for through-hole component placement.

The direct Bourns substitute 3262W-1-502LF maintains identical dimensions and all electrical parameters while differing in RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

3262W-1-502LF (Bourns Inc.): This part is the direct manufacturer equivalent with identical electrical and mechanical specifications. Selection of 3262W-1-502LF is appropriate when RoHS3 compliance is required or when REACH-affected material sourcing must be avoided. Dimensional compatibility is exact.

64WR5KLF and 64YR5KLF (TT Electronics/BI Technologies): These parts provide RoHS compliance and REACH-unaffected status. Both feature a 0.005" (0.13mm) reduction in the secondary face dimension (0.165" versus 0.170"). Selection is appropriate when compliance certifications are prioritized and PCB layout accommodates the minor dimensional variance. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints.

All substitute parts maintain Active product status and are electrically equivalent within the specified tolerance and temperature coefficient parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. The 3262W-1-502LF maintains identical electrical parameters (5 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C) and mechanical dimensions (0.250" x 0.170" face). The primary difference is RoHS3 compliance status.

Q: What is the dimensional impact of substituting 64WR5KLF or 64YR5KLF?

A: The secondary face dimension is reduced from 0.170" to 0.165" (0.005" or 0.13mm reduction). The primary dimension (0.250") remains unchanged. This variance is within standard PCB layout tolerances for through-hole components.

Q: Are all substitute parts electrically equivalent?

A: Yes. All substitute parts (3262W-1-502LF, 64WR5KLF, 64YR5KLF) maintain identical resistance (5 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), resistive material (cermet), and termination style (PC pins).

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

A: 3262W-1-502LF (ROHS3 Compliant), 64WR5KLF (RoHS Compliant), or 64YR5KLF (RoHS Compliant) are all suitable. Selection depends on dimensional requirements and REACH compliance needs.

Q: What is the difference between 64WR5KLF and 64YR5KLF?

A: Both parts are manufactured by TT Electronics/BI Technologies and maintain identical electrical and mechanical specifications. No functional difference exists between these two part numbers for this application.

Q: Are there moisture sensitivity considerations for substitute parts?

A: The original 3262W-1-502 and 3262W-1-502LF have MSL ratings listed as Not Applicable. The 64WR5KLF and 64YR5KLF have MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
