Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3269W-1-502 are qualified based on matching the following critical parameters: resistance value (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 (surface mount), and physical dimensions (0.250" x 0.170" face). The identified substitutes are the TT Electronics/BI 84WR5KLF and 84WR5KLFTR, which maintain electrical equivalence while differing in termination style (surface mount vs. Gull Wing) and packaging format (Tube vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The 84WR5KLF and 84WR5KLFTR are electrically and mechanically equivalent to the 3269W-1-502. Both substitute parts offer improved compliance status: RoHS Compliant and REACH Unaffected, compared to the main part's non-compliant and REACH Affected status. Both substitutes also provide superior moisture sensitivity ratings (MSL 1, Unlimited) versus the main part (MSL 2, 1 Year). Selection between 84WR5KLF and 84WR5KLFTR depends on packaging requirements: Tube packaging for 84WR5KLF or Tape & Reel for 84WR5KLFTR. The termination style difference (Gull Wing vs. Surface Mount) must be evaluated for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Are the 84WR5KLF and 84WR5KLFTR electrically identical to the 3269W-1-502?

A: Yes. Both substitute parts match all critical electrical parameters: 5 kOhms resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, Cermet material, and identical physical dimensions (0.250" x 0.170" face).

Q: What is the difference between 84WR5KLF and 84WR5KLFTR?

A: The primary difference is packaging format. The 84WR5KLF is supplied in Tube packaging, while the 84WR5KLFTR is supplied in Tape & Reel (TR) format. Both parts are electrically and mechanically identical.

Q: Can the 84WR series parts replace the 3269W-1-502 on existing PCBs?

A: Termination style compatibility must be verified. The 3269W-1-502 uses Gull Wing termination, while the 84WR5KLF and 84WR5KLFTR use Surface Mount termination. PCB pad design and soldering process compatibility must be assessed before substitution.

Q: What compliance advantages do the substitute parts offer?

A: The 84WR5KLF and 84WR5KLFTR are RoHS Compliant and REACH Unaffected, whereas the 3269W-1-502 is RoHS non-compliant and REACH Affected. The substitutes also provide improved moisture sensitivity (MSL 1, Unlimited vs. MSL 2, 1 Year).

Q: Are there inventory considerations for these substitutes?

A: The 84WR5KLFTR (Tape & Reel) has higher inventory availability (2464 Pcs) compared to 84WR5KLF (Tube, 1221 Pcs). The main part 3269W-1-502 has 853 Pcs in stock.
