Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3224X-2-202G are qualified based on matching the following critical parameters: 2 kOhms resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, top adjustment type, Cermet resistive material, and surface mount mounting type. The identified substitutes are the TT Electronics/BI 84WR2KLF and 84WR2KLFTR, which satisfy all electrical specifications. Packaging format differences (Tape & Reel versus Tube) do not affect electrical or mechanical compatibility and represent alternative supply chain options.

Parameter Comparison

Engineering Selection Recommendations

The 84WR2KLFTR represents the closest substitute to the 3224X-2-202G, matching all electrical parameters and offering identical Tape & Reel packaging format. Both components maintain Active product status and satisfy RoHS compliance requirements. The 84WR2KLF provides equivalent electrical performance with alternative Tube packaging, suitable for applications where packaging format flexibility is acceptable. Physical dimension differences between the Bourns Gull Wing termination (4.80mm x 4.60mm) and TT Electronics Surface Mount termination (6.35mm x 4.32mm) require PCB layout verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Are the electrical specifications identical between the main part and substitutes? A: Yes. The 3224X-2-202G, 84WR2KLF, and 84WR2KLFTR share identical resistance (2 kOhms), power rating (0.25W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (12), adjustment type (top adjustment), and resistive material (Cermet).

Q: What is the difference between 84WR2KLF and 84WR2KLFTR? A: Both parts are electrically and mechanically identical. The primary difference is packaging: 84WR2KLF is supplied in Tube format, while 84WR2KLFTR is supplied in Tape & Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Do the physical dimensions differ between parts? A: Yes. The 3224X-2-202G has a face dimension of 0.189" x 0.138" (4.80mm x 4.60mm) with Gull Wing termination. The 84WR2KLF and 84WR2KLFTR have a face dimension of 0.250" x 0.170" (6.35mm x 4.32mm) with Surface Mount termination. PCB layout and footprint compatibility must be confirmed before substitution.

Q: Are compliance certifications equivalent? A: Both the main part (RoHS3 Compliant) and substitutes (RoHS Compliant) meet RoHS requirements. The 3224X-2-202G carries REACH Affected status, while the 84WR series carries REACH Unaffected status. Regulatory requirements for your application should be verified.

Q: Can these parts be used interchangeably in production? A: Electrical interchangeability is confirmed. Physical footprint differences require PCB design verification. Packaging format selection (Tube versus Tape & Reel) depends on assembly equipment and supply chain logistics.
