Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3339P-1-504 are identified based on matching all critical electrical and mechanical parameters: resistance value (500 kOhms), power rating (0.5W), 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), and physical dimensions (0.300" diameter). The primary distinction between the main part and its substitute relates to RoHS compliance status and lead finish specifications, which do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 3339P-1-504LF serves as a direct electrical and mechanical substitute for the 3339P-1-504. Both parts maintain identical performance characteristics across all functional parameters. The primary distinction is RoHS3 compliance status of the 3339P-1-504LF, which is relevant for applications subject to RoHS directives. Selection between these parts should be based on regulatory requirements applicable to the end application and current inventory availability. Both parts are active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Are the 3339P-1-504 and 3339P-1-504LF electrically interchangeable?

A: Yes. Both parts have identical resistance values (500 kOhms), power ratings (0.5W), tolerance (±10%), temperature coefficients (±100ppm/°C), and all other electrical specifications. They are direct functional equivalents.

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

A: The 3339P-1-504LF carries ROHS3 compliance certification, while the 3339P-1-504 is RoHS non-compliant. The "LF" suffix typically indicates lead-free termination. Electrical and mechanical performance are identical.

Q: Can I use the 3339P-1-504LF in place of the 3339P-1-504 in existing designs?

A: Yes, provided your application does not have specific requirements for the non-compliant version. The RoHS3 compliant variant is suitable for all applications where RoHS compliance is required or preferred.

Q: Are the physical dimensions identical?

A: Yes. Both parts are Round - 0.300" Dia (7.62mm) with identical mounting and termination specifications. They are mechanically interchangeable.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there inventory differences between these parts?

A: The 3339P-1-504 has 832 units in stock, while the 3339P-1-504LF has 714 units available. Inventory levels may vary based on current demand and supply conditions.
