Key Parameters

Substitute Part Grouping Explanation

Substitution for the PVC6E251C01B00 is determined by the following critical parameters:

• Resistance Value: 250 Ohms (primary functional requirement)
• Power Rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature Coefficient: ±100ppm/°C or better
• Number of Turns: 1 turn
• Adjustment Type: Side Adjustment
• Mounting Type: Through Hole
• Termination Style: PC Pins

The substitute part 3362W-1-252 shares identical electrical specifications for power rating, tolerance, temperature coefficient, number of turns, adjustment type, mounting, and termination. However, it operates at 2.5 kOhms resistance with cermet resistive material instead of ceramic, placing it in a different functional category. This part is suitable only for applications where the 2.5 kOhm resistance value is acceptable and the cermet material properties meet circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 3362W-1-252 is an active product from Bourns Inc. with current manufacturing and availability, addressing the obsolescence of the PVC6E251C01B00. However, direct substitution is not applicable due to the significant resistance value difference (250 Ohms vs. 2.5 kOhms). This part is suitable only for circuits designed for 2.5 kOhm trimmer potentiometers.

For applications requiring the original 250 Ohm specification, alternative sources must be evaluated. The PVC6E251C01B00 remains RoHS3 compliant, while the 3362W-1-252 is RoHS non-compliant, which may impact regulatory requirements depending on end-use application and regional standards.

The cermet resistive material in the 3362W-1-252 provides different performance characteristics compared to the ceramic material in the original part, including variations in frequency response, noise characteristics, and long-term stability.

Frequently Asked Questions (FAQ)

Q: Can the 3362W-1-252 directly replace the PVC6E251C01B00?

A: No. While both parts share identical power ratings, tolerance, temperature coefficient, number of turns, adjustment type, mounting, and termination, the resistance values differ significantly (250 Ohms vs. 2.5 kOhms). Direct substitution is only valid if the circuit is designed for 2.5 kOhm operation.

Q: What are the key differences between these parts?

A: The primary differences are resistance value (250 Ohms vs. 2.5 kOhms), resistive material (ceramic vs. cermet), physical dimensions (8.00mm x 6.90mm vs. 6.99mm x 6.60mm), product status (obsolete vs. active), and RoHS compliance status (RoHS3 compliant vs. non-compliant).

Q: Why is the PVC6E251C01B00 obsolete?

A: The part is classified as obsolete by the manufacturer. The 3362W-1-252 represents an active alternative from the same manufacturer, though at a different resistance value.

Q: Are the physical dimensions compatible?

A: The dimensions are similar but not identical. The PVC6E251C01B00 measures 8.00mm x 6.90mm, while the 3362W-1-252 measures 6.99mm x 6.60mm. PCB layout and mechanical clearance must be verified before substitution.

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

A: Ceramic and cermet materials exhibit different electrical and thermal characteristics. Cermet typically offers better frequency response and lower noise, while ceramic provides different temperature stability profiles. Material selection depends on circuit performance requirements.

Q: Does RoHS compliance affect substitution?

A: RoHS compliance status may be critical depending on the application and regional regulations. The original part is RoHS3 compliant, while the substitute is RoHS non-compliant. Regulatory requirements must be evaluated before substitution.
