Substitute Part Grouping Explanation

Substitution eligibility for the 3339H-1-202LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 4
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Regulatory compliance: RoHS3 and ECCN EAR99

The substitute part PV12P202A01B00 meets all electrical and mechanical parameters required for direct substitution. Dimensional tolerance (0.299" vs 0.300") remains within acceptable mechanical clearance for standard PCB through-hole layouts. Packaging format differs (Bulk vs Tube) but does not affect functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 3339H-1-202LF and PV12P202A01B00 are Active products manufactured by Bourns Inc. with identical electrical specifications and RoHS3 compliance. Selection between these parts should be based on:

• Packaging requirements: 3339H-1-202LF is supplied in Tube packaging; PV12P202A01B00 is supplied in Bulk packaging
• Inventory availability: PV12P202A01B00 currently has higher stock levels (1228 pcs vs 624 pcs)
• Series preference: 3339H-1-202LF belongs to the Trimpot® 3339 sealed series; PV12P202A01B00 belongs to the PV12 series
• Dimensional tolerance: Both parts are mechanically compatible within standard PCB through-hole specifications

Frequently Asked Questions (FAQ)

Q: Can PV12P202A01B00 be used as a direct replacement for 3339H-1-202LF?

A: Yes. Both parts share identical electrical parameters (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 4-turn adjustment) and mechanical compatibility (through-hole PC pin termination, cermet material, top adjustment). Dimensional difference (0.299" vs 0.300") is within acceptable tolerance for standard PCB layouts.

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging (3339H-1-202LF) provides individual component protection in a reel format suitable for automated assembly. Bulk packaging (PV12P202A01B00) supplies components in loose form, typically for manual assembly or lower-volume applications. Functional performance is identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 3339H-1-202LF and PV12P202A01B00 are RoHS3 compliant and carry EAR99 export classification.

Q: What determines substitution eligibility for this trimmer potentiometer?

A: Substitution is valid when resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style are identical. Packaging format and series designation do not affect electrical or mechanical compatibility.

Q: Can I mix these parts in the same assembly?

A: Yes. Both parts meet identical electrical and mechanical specifications and can be used interchangeably within the same circuit design and PCB layout.
