Key Parameters

Substitute Part Grouping Explanation

The 3362P-1-251LF qualifies as a direct substitute for the PVC6A251A01B00 based on the following critical parameters:

• Identical resistance value: 250 Ohms
• Matching power rating: 0.5W (1/2W)
• Equivalent tolerance: ±10%
• Same temperature coefficient: ±100ppm/°C
• Identical number of turns: 1
• Same adjustment type: Top Adjustment
• Matching mounting type: Through Hole
• Same termination style: PC Pins

The primary difference is the resistive material composition (ceramic versus cermet) and physical dimensions, which remain within acceptable mechanical compatibility for standard PCB layouts. The 3362P series represents the current production equivalent with active status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 3362P-1-251LF is the appropriate substitute for the obsolete PVC6A251A01B00. Selection is based on:

• Product status: The 3362P-1-251LF maintains active production status, ensuring long-term availability and supply chain reliability.
• Compliance: The substitute achieves ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing.
• Electrical equivalence: All critical electrical parameters (resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics) are identical.
• Mechanical compatibility: Physical dimensions are comparable within standard PCB layout tolerances for through-hole components.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-251LF be used as a direct replacement for the PVC6A251A01B00 in existing designs?

A: Yes. The electrical specifications are identical across all critical parameters. PCB footprints require minimal adjustment due to slight dimensional differences (approximately 0.003" variation in width and height), which fall within standard manufacturing tolerances for through-hole component placement.

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

A: Both materials meet the specified electrical parameters for this application. Cermet (ceramic-metal composite) used in the 3362P series offers improved stability and reliability characteristics compared to ceramic, contributing to the active product status and compliance certifications.

Q: Is the 3362P-1-251LF available in the same packaging as the PVC6A251A01B00?

A: The 3362P-1-251LF is supplied in tube packaging, whereas the original part number does not specify packaging format. Both are through-hole components suitable for standard PCB assembly processes.

Q: Why is the PVC6A251A01B00 classified as obsolete?

A: The PVC6 series has been superseded by the Trimpot® 3362 series, which offers improved performance, better compliance status, and active manufacturing support. Bourns Inc. recommends transitioning to the 3362P series for new designs.

Q: Are there any compliance differences between these parts?

A: Yes. The PVC6A251A01B00 is RoHS non-compliant, while the 3362P-1-251LF is ROHS3 compliant. The substitute also carries REACH Affected status compared to REACH Unaffected for the original part. These differences are significant for applications subject to environmental regulations.
