Substitute Part Grouping Explanation

Substitution eligibility for the PVC6E253A01B00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1.0 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

The 3362S-1-253LF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the resistive material differs (Cermet vs. Ceramic) and physical dimensions vary slightly, these differences do not affect functional equivalence within the specified parameter constraints.

Engineering Selection Recommendations

The 3362S-1-253LF is the qualified substitute for the obsolete PVC6E253A01B00. Selection between these parts should be based on the following factors:

Product Status: The PVC6E253A01B00 is obsolete with no ongoing manufacturing. The 3362S-1-253LF maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The 3362S-1-253LF is ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements. The PVC6E253A01B00 is non-compliant with RoHS and unaffected by REACH, reflecting its legacy status.

Physical Dimensions: The 3362S-1-253LF is slightly smaller (6.99mm x 6.60mm vs. 8.00mm x 6.90mm). PCB layout verification is required to confirm fit within existing mounting footprints.

Resistive Material: The 3362S-1-253LF uses Cermet material versus the ceramic material in the PVC6E253A01B00. Both materials meet the specified electrical parameters and tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3362S-1-253LF directly replace the PVC6E253A01B00 in existing designs?

A: Yes, provided that the smaller physical dimensions (6.99mm x 6.60mm vs. 8.00mm x 6.90mm) are compatible with the PCB layout. All critical electrical parameters—resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics—are identical.

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

A: Both materials meet the specified ±10% tolerance and ±100ppm/°C temperature coefficient. The Cermet material in the 3362S-1-253LF offers improved stability and is used in the active production series.

Q: Does the change in RoHS status affect functionality?

A: No. RoHS compliance is a regulatory and environmental requirement, not a functional parameter. The 3362S-1-253LF's ROHS3 compliance makes it suitable for applications requiring current environmental standards.

Q: Are there packaging differences between these parts?

A: The PVC6E253A01B00 packaging is unspecified, while the 3362S-1-253LF is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What should be verified before implementing the 3362S-1-253LF as a replacement?

A: Verify PCB footprint compatibility given the dimensional difference. Confirm that the tube packaging meets your assembly requirements. No electrical re-qualification is necessary due to parameter equivalence.
