• Temperature coefficient: ±100ppm/°C
• Number of turns: 4
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical size: Round - 0.300" Dia (7.62mm)
• Series family: Trimpot® 3339 - Sealed

The 3339P-1-502LF meets all electrical and mechanical specifications required for direct substitution. The primary distinction is product status and packaging configuration, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The 3339P-1-502LF is the direct functional equivalent of the 3339P-1-502. Selection between these parts should be based on the following factors:

Product Availability: The 3339P-1-502 is discontinued at DiGi Electronics. The 3339P-1-502LF maintains active product status with current inventory availability.

Regulatory Compliance: The 3339P-1-502LF carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant. For applications subject to RoHS requirements, the 3339P-1-502LF is the appropriate selection.

Packaging Configuration: The 3339P-1-502LF is supplied in tube packaging. Verify packaging compatibility with receiving and assembly processes.

Electrical and Mechanical Equivalence: All functional parameters—resistance, power rating, tolerance, temperature coefficient, adjustment mechanism, and physical dimensions—are identical between both parts.

Frequently Asked Questions (FAQ)

Q: Can the 3339P-1-502LF be used as a direct replacement for the 3339P-1-502?

A: Yes. The 3339P-1-502LF meets all electrical and mechanical specifications of the original part. Both components share identical resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting configuration, termination style, and physical dimensions.

Q: What is the difference between these two part numbers?

A: The primary differences are product status, RoHS compliance level, and packaging. The 3339P-1-502 is discontinued and RoHS non-compliant, while the 3339P-1-502LF is active, ROHS3 compliant, and supplied in tube packaging.

Q: Are there any compatibility concerns when substituting the 3339P-1-502LF for the 3339P-1-502?

A: No compatibility concerns exist from an electrical or mechanical standpoint. Verify that tube packaging is compatible with your assembly process if the original part was supplied in different packaging.

Q: Does the RoHS compliance difference affect circuit performance?

A: RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical functional characteristics in circuit operation.

Q: What is the physical footprint of these trimmer potentiometers?

A: Both parts feature a round form factor with 0.300" diameter (7.62mm). Through-hole PC pin termination is standard for both components.
