Key Parameters

Substitute Part Grouping Explanation

The 3362R-1-254LF qualifies as a direct substitute for the PVC6D254A01B00 based on the following critical parameters:

• Identical resistance value: 250 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 1.0 Turn
• Identical adjustment type: Top Adjustment
• Identical mounting type: Through Hole
• Identical termination style: PC Pins

The primary difference is the resistive material composition (Cermet vs. Ceramic) and physical dimensions, which remain within acceptable mechanical compatibility for PC pin through-hole applications. The 3362R-1-254LF is an active product with current manufacturing status, addressing the obsolescence issue of the original part.

Parameter Comparison

Engineering Selection Recommendations

The 3362R-1-254LF is the appropriate substitute for the PVC6D254A01B00 based on the following factors:

All critical electrical parameters are identical, ensuring functional equivalence in circuit applications. The 3362R-1-254LF maintains active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete PVC6D254A01B00. The substitute achieves ROHS3 compliance, addressing regulatory requirements for new designs and production environments where RoHS compliance is mandated. Physical dimensions are comparable within standard through-hole PCB mounting tolerances. The Cermet resistive material in the substitute provides equivalent performance characteristics within the specified tolerance and temperature coefficient ranges.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-254LF be used as a direct replacement for the PVC6D254A01B00 in existing designs?

A: Yes. All electrical parameters—resistance, power rating, tolerance, temperature coefficient, and number of turns—are identical. Physical dimensions are comparable for through-hole PC pin mounting. No circuit redesign is required.

Q: What is the difference between Ceramic and Cermet resistive materials in this application?

A: Both materials meet the specified tolerance (±10%) and temperature coefficient (±100ppm/°C) for this 250 kOhms trimmer potentiometer. Cermet material in the 3362R-1-254LF provides equivalent electrical performance within the defined parameters.

Q: Does the RoHS compliance difference affect substitution?

A: The 3362R-1-254LF is ROHS3 compliant, while the PVC6D254A01B00 is non-compliant. For new production or designs subject to RoHS regulations, the 3362R-1-254LF is the required choice. For legacy systems without RoHS requirements, both parts are electrically equivalent.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: The face dimensions differ slightly (0.272" vs. 0.275" width; 0.272" vs. 0.260" height). These variations are within standard through-hole PCB mounting tolerances. Verify specific PCB footprint requirements for your application.

Q: What is the packaging difference between these parts?

A: The PVC6D254A01B00 is supplied in standard packaging, while the 3362R-1-254LF is supplied in Tube packaging. This does not affect electrical or mechanical compatibility.
