Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3329P-DK9-102 are qualified based on electrical parameter equivalence: identical resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). Physical dimensions may vary within the constraints of through-hole mounting compatibility. All substitute parts maintain active product status and are available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and functional requirements for 1 kOhm, 0.5W through-hole trimmer potentiometer applications. Selection between the 3329P-DK9-102 and its substitutes should consider regulatory compliance requirements. The 25PR1KLF and 82PR1KLF offer RoHS compliance and REACH unaffected status, which may be advantageous for applications subject to environmental regulations. The 82PR1KLF maintains identical physical dimensions to the 3329P-DK9-102 (round 0.250" diameter), while the 25PR1KLF uses a square form factor (0.270" x 0.270"). Physical form factor compatibility with PCB layout and mechanical constraints should be verified during design integration.

Frequently Asked Questions (FAQ)

Q: Can the 25PR1KLF be used as a direct replacement for the 3329P-DK9-102?

A: The 25PR1KLF is electrically equivalent and functionally compatible. However, it uses a square form factor (0.270" x 0.270") compared to the round 0.250" diameter of the 3329P-DK9-102. PCB layout and mechanical clearance must accommodate the different physical geometry.

Q: What is the difference between the 25PR1KLF and 82PR1KLF substitutes?

A: Both parts are electrically identical to the 3329P-DK9-102. The primary differences are physical form factor (25PR1KLF is square; 82PR1KLF is round) and packaging (25PR1KLF supplied in tube; 82PR1KLF supplied in bulk). The 82PR1KLF maintains the same round 0.250" diameter as the original part.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The 3329P-DK9-102 is RoHS non-compliant and REACH affected. Both substitute parts (25PR1KLF and 82PR1KLF) are RoHS compliant and REACH unaffected, which may be required for certain applications or markets.

Q: Which substitute part should I select for direct PCB layout compatibility?

A: The 82PR1KLF maintains identical round form factor and 0.250" diameter dimensions as the 3329P-DK9-102, making it the preferred choice for direct PCB layout substitution without mechanical redesign.

Q: Are all parts available in production quantities?

A: Yes. The 3329P-DK9-102 has 713 units in stock, the 25PR1KLF has 12,299 units in stock, and the 82PR1KLF has 2,806 units in stock.
