Substitute Part Grouping Explanation

Substitute parts for the 72PMR2KLF are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical resistance (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and number of turns (1).

Mechanical Compatibility: All substitutes feature top adjustment, cermet resistive material, through-hole mounting, and PC pin termination.

Functional Interchangeability: Substitutes are grouped by manufacturer series and physical form factor. The 3362 series (rectangular 0.275" × 0.260" face) and 3386 series (square 0.375" × 0.375" face) represent distinct mechanical envelopes. The 3386 series maintains the same square footprint as the 72PMR2KLF, enabling direct mechanical replacement. The 3362 series offers a smaller rectangular form factor and is suitable for space-constrained applications where mechanical envelope differences are acceptable.

Regulatory Compliance: RoHS3 compliance is maintained across all recommended substitutes except 3362P-1-202, which is RoHS non-compliant.

Engineering Selection Recommendations

Direct Mechanical Replacement (Same Form Factor): The 3386 series substitutes (3386F-1-202LF, 3386G-1-202LF, 3386K-1-202LF) maintain the square 0.375" × 0.375" footprint of the 72PMR2KLF and are suitable for applications where PCB layout constraints require identical mechanical envelope. All three are ROHS3 compliant and active in production. The 3386F-1-202LF offers the highest inventory availability at 4817 units.

Space-Optimized Alternative (Smaller Form Factor): The 3362 series substitutes provide a rectangular 0.275" × 0.260" form factor, reducing board space requirements. Among these options, the 3362P-1-202LF is ROHS3 compliant with the highest inventory (30400 units) and is recommended for new designs. The 3362U-1-202LF and 3362R-1-202LF are also ROHS3 compliant alternatives with adequate stock levels. The 3362P-1-202 is RoHS non-compliant and should be avoided in applications subject to RoHS regulations.

Packaging Considerations: Most substitutes are supplied in tube packaging. The 3362U-1-202RLF is available in tape and reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 3362 series be used as a direct replacement for the 72PMR2KLF?

A: The 3362 series is electrically and functionally equivalent but has a smaller rectangular form factor (0.275" × 0.260") compared to the square 0.375" × 0.375" footprint of the 72PMR2KLF. Substitution is possible if PCB layout accommodates the different mechanical envelope.

Q: What is the difference between the 3362 series variants (F, H, P, R, U)?

A: The letter designations represent different mechanical adjustment styles and internal construction. All variants maintain identical electrical specifications (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C). Selection depends on application-specific adjustment requirements and mechanical interface preferences.

Q: Is the 3362P-1-202 suitable for new designs?

A: The 3362P-1-202 is RoHS non-compliant. For applications requiring RoHS3 compliance, use the 3362P-1-202LF variant instead, which is electrically identical and RoHS3 compliant.

Q: Which substitute offers the best availability?

A: The 3362P-1-202LF has the highest inventory at 30400 units and is ROHS3 compliant, making it the optimal choice for applications where form factor differences are acceptable.

Q: Are all substitutes rated for the same power dissipation?

A: Yes. All listed substitutes are rated at 0.5W (1/2W) with identical tolerance (±10%) and temperature coefficient (±100ppm/°C), ensuring equivalent thermal performance.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is suitable for manual assembly and lower-volume applications. Tape and reel packaging (3362U-1-202RLF) is designed for automated pick-and-place assembly processes. Electrical and mechanical specifications are identical.
