Key Parameters

Substitute Part Grouping Explanation

The 3362X-1-254LF qualifies as a direct substitute for the PVC6H254A01B00 based on the following matching parameters:

• 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: Side Adjustment (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)

The primary difference is the resistive material composition (ceramic versus cermet) and physical dimensions, which do not affect electrical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The 3362X-1-254LF is the appropriate substitute for the obsolete PVC6H254A01B00. Selection is based on:

• Identical electrical specifications across all critical parameters (resistance, power rating, tolerance, temperature coefficient, adjustment characteristics)
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance, meeting current regulatory requirements for new designs and production
• Same manufacturer (Bourns Inc.) ensuring consistent quality and performance standards
• Functional equivalence in through-hole PC pin applications

The cermet resistive material in the substitute provides equivalent performance to the ceramic material in the original part within the specified tolerance and temperature coefficient ranges.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-254LF be used as a direct replacement for the PVC6H254A01B00 in existing designs?

A: Yes. The electrical specifications are identical, including resistance value, power rating, tolerance, temperature coefficient, and adjustment characteristics. The parts are functionally equivalent for circuit applications.

Q: What is the difference between ceramic and cermet resistive materials in these trimmers?

A: Both materials meet the specified tolerance (±10%) and temperature coefficient (±100ppm/°C) for this application. Cermet material in the 3362X-1-254LF provides the same electrical performance as the ceramic material in the PVC6H254A01B00 within the defined parameters.

Q: Are there physical dimension differences between these parts?

A: Yes. The PVC6H254A01B00 has a face dimension of 0.315" x 0.272" (8.00mm x 6.90mm), while the 3362X-1-254LF has a face dimension of 0.275" x 0.260" (6.99mm x 6.60mm). Both are rectangular through-hole packages with side adjustment and PC pin termination. PCB layout compatibility should be verified for your specific application.

Q: Why is the PVC6H254A01B00 obsolete?

A: The PVC6H254A01B00 is classified as obsolete by the manufacturer. The 3362X-1-254LF from the active Trimpot® 3362 series is the current production equivalent.

Q: Does the 3362X-1-254LF meet current compliance requirements?

A: Yes. The 3362X-1-254LF is ROHS3 compliant and REACH affected, meeting current regulatory standards for electronic components in new designs and manufacturing.
