Substitute Part Grouping Explanation

Substitution eligibility for the 3339W-1-502 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 4
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.375" x 0.320" Face (9.53mm x 8.13mm)
• Series: Trimpot® 3339 - Sealed

The substitute part 3339W-1-502LF meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status do not affect functional equivalence but may impact regulatory requirements for specific applications or end markets.

Parameter Comparison

Engineering Selection Recommendations

Both the 3339W-1-502 and 3339W-1-502LF are functionally equivalent and electrically interchangeable. Selection between these parts should be based on regulatory and compliance requirements:

The 3339W-1-502LF is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS Directive 2011/65/EU or equivalent regional regulations. The 3339W-1-502 is RoHS non-compliant and should be selected only for applications where RoHS compliance is not required.

Both parts are REACH Affected and carry EAR99 export classification. Moisture sensitivity level 1 (Unlimited) indicates no moisture sensitivity precautions are required during storage or handling.

Frequently Asked Questions (FAQ)

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

A: Yes. The 3339W-1-502LF is electrically and mechanically equivalent to the 3339W-1-502. All electrical parameters, physical dimensions, and functional characteristics are identical. The primary difference is RoHS compliance status.

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

A: The "LF" suffix in 3339W-1-502LF indicates ROHS3 compliance. The base electrical specifications, resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions are identical between both parts.

Q: Which part should I specify for new designs?

A: Specify the 3339W-1-502LF for new designs unless RoHS exemption is explicitly required. ROHS3 compliance ensures compatibility with current regulatory requirements in most markets.

Q: Are there any package or form factor differences?

A: No. Both parts use identical rectangular form factors with 0.375" x 0.320" face dimensions (9.53mm x 8.13mm). Both are packaged in tubes and feature PC pin through-hole termination.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity. Standard handling and storage practices are sufficient.
