Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6Q253A01B00 is determined by matching the following critical parameters: resistance value (25 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (side adjustment), mounting type (through hole), and termination style (PC pins).

The 3362M-1-253LF qualifies as a direct substitute based on these core electrical and mechanical specifications. Both components share identical resistance, power rating, tolerance, temperature coefficient, turn count, adjustment mechanism, mounting configuration, and pin termination. The primary difference is the resistive material composition: the PVC6Q uses ceramic while the 3362M uses cermet. This material difference does not affect functional compatibility within the specified electrical parameters. Physical dimensions vary slightly (0.275" x 0.260" versus 0.315" x 0.272"), which must be evaluated against PCB layout constraints.

Parameter Comparison

Engineering Selection Recommendations

The 3362M-1-253LF is the qualified substitute for the PVC6Q253A01B00. Selection should be based on the following factors:

Product Status: The PVC6Q253A01B00 is obsolete, while the 3362M-1-253LF is active. Active product status ensures continued availability and manufacturing support.

Regulatory Compliance: The 3362M-1-253LF is ROHS3 compliant, whereas the PVC6Q253A01B00 is non-compliant. For applications subject to RoHS regulations, the 3362M-1-253LF is the required choice.

Physical Dimensions: The 3362M-1-253LF is smaller (0.275" x 0.260" versus 0.315" x 0.272"). Verify that the reduced footprint accommodates existing PCB layout and mechanical constraints.

Resistive Material: The cermet material in the 3362M-1-253LF provides sealed construction compared to the ceramic material in the PVC6Q253A01B00. This offers enhanced environmental protection in applications exposed to moisture or contaminants.

Electrical Equivalence: All critical electrical parameters are identical, ensuring functional interchangeability within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can the 3362M-1-253LF directly replace the PVC6Q253A01B00 in existing designs?

A: Yes, the 3362M-1-253LF is electrically equivalent across all specified parameters: 25 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, through-hole mounting, and PC pin termination. Physical dimensions must be verified against PCB layout constraints.

Q: What is the significance of the resistive material difference between ceramic and cermet?

A: Both ceramic and cermet materials meet the specified electrical parameters. Cermet construction in the 3362M-1-253LF provides sealed design characteristics, offering improved resistance to environmental factors such as moisture and contamination compared to ceramic construction.

Q: Why is the 3362M-1-253LF smaller than the PVC6Q253A01B00?

A: The 3362M-1-253LF (0.275" x 0.260") represents a more compact design iteration within the Trimpot® 3362 series. The reduced dimensions do not affect electrical performance but require confirmation that the component fits within existing PCB footprints and mechanical assemblies.

Q: Is the 3362M-1-253LF suitable for RoHS-regulated applications?

A: Yes, the 3362M-1-253LF is ROHS3 compliant. The PVC6Q253A01B00 is non-compliant. For applications subject to RoHS directives, the 3362M-1-253LF is the appropriate selection.

Q: Are there any packaging differences between these parts?

A: The PVC6Q253A01B00 packaging information is not specified in the available data. The 3362M-1-253LF is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What is the availability status of each part?

A: The PVC6Q253A01B00 is obsolete with 994 pieces in current inventory. The 3362M-1-253LF is active with 1643 pieces in current inventory, ensuring ongoing supply chain support.
