Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC6H504A01B00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1.0 Turn
• Adjustment type: Side Adjustment
• Mounting type: Through Hole
• Termination style: PC Pins

The 3362X-1-504LF meets all functional and electrical requirements for direct substitution. While the resistive material differs (Cermet vs. Ceramic) and physical dimensions are slightly smaller, these variations remain within acceptable mechanical and electrical compatibility parameters for through-hole PC pin applications.

Parameter Comparison

Engineering Selection Recommendations

The 3362X-1-504LF is the direct functional equivalent for the obsolete PVC6H504A01B00. Selection of this substitute is supported by:

• Active product status ensuring continued availability and supply chain stability
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Identical electrical specifications across all critical parameters
• Smaller physical footprint, which may provide PCB layout advantages
• Cermet resistive material construction, which provides enhanced stability characteristics compared to ceramic

The substitute part is suitable for direct replacement in applications where the original PVC6H504A01B00 was specified, provided PCB layout accommodates the reduced dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-504LF be used as a direct replacement for the PVC6H504A01B00?

A: Yes. Both parts share identical electrical specifications: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn adjustment, side adjustment type, through-hole mounting, and PC pin termination. The substitute is mechanically compatible with existing PCB designs.

Q: What is the difference between Ceramic and Cermet resistive materials in these trimmers?

A: Both materials are used in precision trimmer potentiometers. Cermet (ceramic-metal composite) construction in the 3362X-1-504LF provides enhanced stability and performance characteristics. The electrical specifications remain equivalent for the specified parameters.

Q: Are there packaging differences between these parts?

A: The PVC6H504A01B00 is obsolete with no current packaging specification. The 3362X-1-504LF is supplied in Tube packaging as an active product.

Q: Does the smaller physical size of the 3362X-1-504LF affect compatibility?

A: The 3362X-1-504LF has a smaller face dimension (0.275" x 0.260" vs. 0.315" x 0.272"). This reduction is typically accommodated in through-hole PCB designs. Verify PCB layout clearances before implementation.

Q: What compliance advantages does the substitute provide?

A: The 3362X-1-504LF is ROHS3 compliant and REACH affected, addressing modern regulatory requirements. The original PVC6H504A01B00 is RoHS non-compliant and REACH unaffected.
