Key Parameters

Substitute Part Grouping Explanation

The 3362P-1-254LF qualifies as a direct substitute for the PVC6A254A01B00 based on the following matching 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 Turn
• Identical adjustment type: Top Adjustment
• Identical mounting type: Through Hole
• Identical termination style: PC Pins

The primary difference is the resistive material composition (ceramic versus cermet) and physical dimensions, which remain within acceptable mechanical compatibility for PC pin through-hole applications. The substitute part is from the same manufacturer and maintains all critical electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 3362P-1-254LF is the appropriate substitute for the obsolete PVC6A254A01B00. Selection is based on:

• Product status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Regulatory compliance: The 3362P-1-254LF meets ROHS3 compliance requirements, whereas the original part is non-compliant. For applications subject to RoHS directives, the substitute is mandatory.
• Electrical equivalence: All critical electrical parameters match exactly, ensuring functional compatibility in circuit applications.
• Mechanical compatibility: Both parts feature PC pin termination and through-hole mounting, maintaining PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-254LF be used as a direct replacement for the PVC6A254A01B00?

A: Yes. The substitute maintains identical electrical specifications (250 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment) and compatible mechanical form factor (through-hole PC pins). Physical dimensions are similar and suitable for standard PCB layouts designed for the original part.

Q: What is the difference between ceramic and cermet resistive materials in this application?

A: Both materials meet the specified electrical parameters for this 250 kOhms trimmer potentiometer. Cermet (ceramic-metal composite) used in the 3362P series offers improved stability and reliability characteristics compared to ceramic material. The electrical performance remains equivalent for the stated tolerance and temperature coefficient specifications.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance restricts hazardous substances in electrical equipment. The original PVC6A254A01B00 is non-compliant, while the 3362P-1-254LF is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute is necessary to meet compliance obligations.

Q: Are there any packaging differences between these parts?

A: The PVC6A254A01B00 is supplied in standard packaging, while the 3362P-1-254LF is supplied in tube packaging. This difference does not affect electrical or mechanical compatibility; it only impacts handling and storage procedures.

Q: What is the inventory status of these parts?

A: The PVC6A254A01B00 has 684 pieces in stock but is obsolete. The 3362P-1-254LF has 10,200 pieces in stock and is an active product, providing superior long-term availability for new designs and production continuity.
