Key Parameters

Substitute Part Grouping Explanation

The 3362X-1-253LF qualifies as a direct substitute for the PVC6H253A01B00 based on the following matching parameters:

• Resistance value: 25 kOhms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1 (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 vs. Cermet) and physical dimensions, which do not affect electrical performance within the specified parameters. The substitute part is from the same manufacturer and maintains functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 3362X-1-253LF is the appropriate substitute for the obsolete PVC6H253A01B00. Selection is based on:

• Electrical equivalence across all critical parameters (resistance, power, tolerance, temperature coefficient, turn count)
• Active product status ensuring long-term availability
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Same manufacturer and termination technology, reducing integration risk
• Slightly smaller physical dimensions, which may require PCB layout verification for mechanical fit

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-253LF be used as a direct replacement in existing designs?

A: Yes, provided PCB layout accommodates the slightly smaller dimensions (0.275" x 0.260" vs. 0.315" x 0.272"). All electrical parameters are identical, and PC pin termination is compatible.

Q: What is the difference between Ceramic and Cermet resistive materials in this application?

A: Both materials meet the specified electrical parameters (25 kOhms, ±10% tolerance, ±100ppm/°C). Cermet material in the 3362X series offers improved stability and is used in the sealed Trimpot® 3362 design.

Q: Is the 3362X-1-253LF RoHS compliant?

A: Yes, the 3362X-1-253LF is ROHS3 compliant, whereas the PVC6H253A01B00 is non-compliant. This makes the substitute suitable for applications with RoHS requirements.

Q: Are there packaging differences between these parts?

A: The PVC6H253A01B00 packaging is not specified in available data. The 3362X-1-253LF is supplied in Tube packaging.

Q: What is the impact of the smaller physical size on circuit performance?

A: Physical size does not affect electrical performance. Verification is required only for mechanical fit on the PCB and clearance around the adjustment screw.
