Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC6Q254C01B00 is determined by the following critical parameters:

• Electrical Specifications: Resistance value (250 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must remain constant
• Mechanical Configuration: Through-hole mounting, PC pin termination, side adjustment mechanism, and single-turn operation are required
• Resistive Material: The original ceramic material may be substituted with cermet, provided all electrical parameters remain within specification
• Compliance: RoHS3 compliance is mandatory; REACH status may differ between active and obsolete parts

The 3362M-1-254LF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 3362M-1-254LF is the qualified substitute for the PVC6Q254C01B00 based on the following factors:

• All critical electrical parameters (resistance, power rating, tolerance, temperature coefficient) are identical
• Mechanical configuration (through-hole, PC pins, side adjustment, single turn) matches exactly
• RoHS3 compliance is maintained, ensuring regulatory alignment
• Active product status provides superior long-term availability and supply chain stability compared to the obsolete PVC6Q254C01B00
• Cermet resistive material offers equivalent performance within the specified tolerance and temperature coefficient ranges
• ECCN and HTSUS classifications remain consistent with export and tariff requirements

Frequently Asked Questions (FAQ)

Q: Can the 3362M-1-254LF be used as a direct replacement for the PVC6Q254C01B00 in existing designs?

A: Yes. All critical electrical and mechanical parameters are identical. The resistive material change from ceramic to cermet does not affect performance within the specified tolerance and temperature coefficient limits.

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

A: Both materials meet the specified ±10% tolerance and ±100ppm/°C temperature coefficient. Cermet construction in the 3362M series provides enhanced reliability and consistency, particularly in sealed configurations.

Q: Are there any dimensional differences between these parts?

A: Yes. The PVC6Q254C01B00 has a face dimension of 0.315" x 0.272" (8.00mm x 6.90mm), while the 3362M-1-254LF measures 0.275" x 0.260" (6.99mm x 6.60mm). Both are rectangular through-hole packages with PC pin termination and will fit standard PCB layouts designed for single-turn side-adjustment trimmers in this resistance and power class.

Q: Does the packaging format affect substitution?

A: The PVC6Q254C01B00 is supplied in standard packaging, while the 3362M-1-254LF is supplied in tube packaging. This difference does not affect electrical or mechanical compatibility; it only impacts handling and inventory management.

Q: Is REACH compliance a concern when substituting these parts?

A: The PVC6Q254C01B00 is REACH Unaffected, while the 3362M-1-254LF is REACH Affected. Both are compliant with applicable regulations. Verify your specific supply chain requirements if REACH status is a critical factor in your procurement process.
