Key Parameters

Substitute Part Grouping Explanation

The 3339W-1-504LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution criteria are determined by the following key parameters:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 4 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Physical dimensions: Rectangular - 0.375" x 0.320" Face (exact match required)
• Series: Trimpot® 3339 - Sealed (exact match required)

The substitute part maintains all functional and mechanical specifications while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 3339W-1-504LF is a direct functional equivalent to the 3339W-1-504. Both parts are active products from Bourns Inc. with identical electrical specifications and physical dimensions. The primary distinction is compliance status: the 3339W-1-504LF carries ROHS3 compliance, while the 3339W-1-504 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both parts maintain REACH Affected status and identical ECCN and HTSUS classifications. Inventory availability is comparable for both variants.

Frequently Asked Questions (FAQ)

Q: Can the 3339W-1-504LF be used as a direct replacement for the 3339W-1-504?

A: Yes. The 3339W-1-504LF is electrically and mechanically identical to the 3339W-1-504. All functional parameters, including resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions, are identical. Both parts are sealed Trimpot® 3339 series components with PC pin termination and side adjustment.

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

A: The primary difference is RoHS compliance status. The 3339W-1-504LF is ROHS3 compliant, while the 3339W-1-504 is RoHS non-compliant. All other specifications, including electrical performance and physical form factor, are identical.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts share identical mounting type (through hole), termination style (PC pins), and physical dimensions (0.375" x 0.320" rectangular face). PCB layout and assembly procedures remain unchanged.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 3339W-1-504LF is the appropriate choice. For applications without RoHS compliance requirements, either part is suitable based on availability and supply chain considerations.

Q: Are both parts currently available?

A: Yes. The 3339W-1-504 has 984 units in stock, and the 3339W-1-504LF has 968 units in stock, both listed as new original inventory.
