Substitute Part Grouping Explanation

Substitution of the PVC6M251A01B00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 250 Ohms (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: Top adjustment
• Mounting type: Through hole
• Termination style: PC pins

The substitute part 3362U-1-251RLF meets all functional and electrical requirements. While the resistive material differs (cermet vs. ceramic), both materials satisfy the specified electrical performance parameters. The substitute maintains identical resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics, with compatible physical dimensions for through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

The 3362U-1-251RLF is a direct functional substitute for the obsolete PVC6M251A01B00. Both components are manufactured by Bourns Inc. and provide identical electrical performance across all specified parameters. The substitute part offers the additional advantage of active product status, ensuring continued availability and supply chain support.

The 3362U-1-251RLF carries ROHS3 compliance, whereas the original part is non-compliant. For applications subject to RoHS regulations, the substitute part satisfies regulatory requirements. The cermet resistive material in the substitute provides equivalent performance to the ceramic material in the original part within the specified tolerance and temperature coefficient ranges.

Physical dimensions are compatible for through-hole PCB mounting, with both parts featuring PC pin termination suitable for standard solder attachment.

Frequently Asked Questions (FAQ)

Q: Can the 3362U-1-251RLF directly replace the PVC6M251A01B00 in existing designs?

A: Yes. Both parts share identical electrical specifications (250 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1.0 turn, top adjustment, through-hole mounting, PC pins). Physical dimensions are compatible for PCB mounting.

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

A: Both materials meet the specified electrical performance parameters for this application. Cermet (ceramic-metal composite) in the 3362U-1-251RLF provides equivalent resistance stability and temperature coefficient performance as the ceramic material in the PVC6M251A01B00.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 3362U-1-251RLF is ROHS3 compliant. The original PVC6M251A01B00 is non-compliant. For applications requiring RoHS compliance, the substitute part satisfies regulatory standards.

Q: What is the packaging difference between these parts?

A: The PVC6M251A01B00 is supplied in standard packaging. The 3362U-1-251RLF is supplied in Tape & Reel (TR) format, which is standard for active production parts and provides advantages for automated assembly processes.

Q: Is the 3362U-1-251RLF currently available?

A: Yes. The 3362U-1-251RLF carries active product status with documented inventory availability, whereas the PVC6M251A01B00 is obsolete.
