Key Parameters

Substitute Part Grouping Explanation

The 3362R-1-253LF is a direct substitute for the 3362R-1-253 based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 25 kOhms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1 (identical)
• Adjustment type: Top Adjustment (identical)
• Resistive material: Cermet (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)
• Physical dimensions: Rectangular - 0.275" x 0.260" Face (6.99mm x 6.60mm) (identical)
• Series: Trimpot® 3362 - Sealed (identical)

The primary distinction between these parts is RoHS compliance status and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 3362R-1-253LF is a direct functional equivalent to the 3362R-1-253. Selection between these parts should be based on the following criteria:

• RoHS Compliance Requirements: Applications subject to RoHS3 regulations must use the 3362R-1-253LF. The 3362R-1-253 is RoHS non-compliant and is unsuitable for such applications.
• Inventory Availability: Both parts are in stock. The 3362R-1-253LF has 895 units available compared to 859 units of the 3362R-1-253.
• Regulatory Status: Both parts are REACH Affected and classified as EAR99 for export control purposes.

No electrical or mechanical performance differences exist between these parts. Selection is determined by compliance requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-253LF be used as a direct replacement for the 3362R-1-253?

A: Yes. All electrical parameters, mechanical dimensions, and functional characteristics are identical. The primary difference is RoHS compliance status.

Q: What is the significance of the "LF" suffix in the 3362R-1-253LF part number?

A: The "LF" designation indicates lead-free construction, which is associated with ROHS3 compliance. The 3362R-1-253 contains lead and is RoHS non-compliant.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical resistance values, power ratings, tolerance, temperature coefficient, adjustment characteristics, and physical dimensions.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use the 3362R-1-253LF. For applications without RoHS requirements, either part is functionally equivalent.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both parts feature PC pin termination and are designed for through-hole mounting with identical footprints.

Q: What is the physical footprint of these trimmer potentiometers?

A: Both parts have a rectangular face measuring 0.275" x 0.260" (6.99mm x 6.60mm).
