Key Parameters

Substitute Part Grouping Explanation

The TT Electronics/BI 64PR1KLF qualifies as a direct electrical substitute for the 3262P-1-102LF based on the following critical parameters:

• Identical resistance value: 1 kOhms
• Matching power rating: 0.25W (1/4W)
• Equivalent tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Same number of turns: 12
• Matching adjustment type: Side Adjustment
• Identical resistive material: Cermet
• Same mounting type: Through Hole
• Matching termination style: PC Pins
• Equivalent HTSUS classification: 8533.40.8050

The primary mechanical difference is the face dimension (square 0.250" x 0.250" versus rectangular 0.250" x 0.185"), which does not affect electrical performance or functional compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the 3262P-1-102LF and 64PR1KLF maintain active product status and comply with applicable regulatory frameworks. The 3262P-1-102LF carries ROHS3 compliance and is REACH Affected, while the 64PR1KLF is RoHS Compliant and REACH Unaffected. Selection between these parts should be based on supply chain availability, regulatory requirements specific to the end application, and PCB layout constraints related to the dimensional difference. The rectangular face profile of the 3262P-1-102LF may provide space advantages in compact layouts, whereas the square profile of the 64PR1KLF offers standard footprint characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 64PR1KLF directly replace the 3262P-1-102LF in existing designs?

A: Yes. Both parts share identical electrical specifications (1 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn side adjustment, cermet resistive material, PC pin termination). The dimensional difference (rectangular versus square face) does not affect electrical function or standard through-hole mounting compatibility.

Q: What is the significance of the face dimension difference?

A: The 3262P-1-102LF has a rectangular face (0.250" x 0.185"), while the 64PR1KLF has a square face (0.250" x 0.250"). This affects only the physical footprint on the PCB. Verify available board space before substitution if layout constraints are critical.

Q: Are there compliance differences between these parts?

A: Yes. The 3262P-1-102LF is ROHS3 Compliant and REACH Affected. The 64PR1KLF is RoHS Compliant and REACH Unaffected. Select based on your application's regulatory requirements and supply chain compliance obligations.

Q: Do both parts use the same packaging?

A: Yes. Both are supplied in tube packaging, ensuring consistent handling and storage requirements.

Q: What inventory levels are available?

A: The 3262P-1-102LF has 1028 pieces in stock, while the 64PR1KLF has 2038 pieces in stock. Availability may vary based on current demand and supply conditions.
