Substitute Part Grouping Explanation

Substitution eligibility for the 3362M-1-503 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.275" x 0.260" Face (6.99mm x 6.60mm)
• Series: Trimpot® 3362 - Sealed

The 3362M-1-503LF is classified as a direct manufacturer equivalent. Both parts are manufactured by Bourns Inc. and share identical electrical and mechanical specifications. The primary distinction is RoHS compliance status, with the 3362M-1-503LF meeting ROHS3 compliance requirements while the original part is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 3362M-1-503 and 3362M-1-503LF are active production parts manufactured by Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3362M-1-503LF is the preferred choice for applications subject to RoHS3 compliance mandates, as it meets ROHS3 requirements. The original 3362M-1-503 remains suitable for applications where RoHS compliance is not a requirement or where legacy component specifications are maintained.

Both parts are REACH Affected and carry EAR99 export classification. Inventory availability should be evaluated based on procurement timelines and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3362M-1-503LF be used as a direct replacement for the 3362M-1-503?

A: Yes. Both parts are electrically and mechanically identical. The 3362M-1-503LF differs only in RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant). Direct substitution is valid from a functional and dimensional perspective.

Q: What is the significance of the "LF" suffix in the 3362M-1-503LF part number?

A: The "LF" suffix indicates lead-free construction and ROHS3 compliance. This designation reflects the manufacturing process and material composition used to meet RoHS3 regulatory requirements.

Q: Are there any dimensional or mounting differences between these parts?

A: No. Both parts share identical physical dimensions (Rectangular - 0.275" x 0.260" Face, 6.99mm x 6.60mm) and through-hole PC pin termination. PCB layout and mounting procedures are identical.

Q: Which part should be selected for new designs?

A: Selection depends on applicable regulatory requirements. For designs subject to RoHS3 compliance mandates, the 3362M-1-503LF is the appropriate choice. Both parts are active production items suitable for new designs.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts provide 50 kOhms resistance with ±10% tolerance, 0.5W power rating, ±100ppm/°C temperature coefficient, and 1-turn side adjustment. Electrical performance is equivalent across all specified parameters.
