PVC6G251A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6G251A01B00 is a 250 Ohm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, side adjustment, and PC pin termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The primary driver for substitution is the discontinued product status, which restricts availability for new procurement and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

The 3362W-1-251LF qualifies as a direct substitute based on the following matching parameters:

• Resistance value: 250 Ohms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1.0 Turn (identical)
• Adjustment type: Side Adjustment (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)

The primary difference is the resistive material composition: the substitute uses Cermet instead of Ceramic. Both materials meet the specified electrical performance parameters and are acceptable for this application category.

Parameter Comparison

Engineering Selection Recommendations

The 3362W-1-251LF is the recommended substitute for the obsolete PVC6G251A01B00. Selection is justified by:

• All critical electrical parameters match exactly (resistance, power rating, tolerance, temperature coefficient, number of turns)
• Identical functional characteristics (side adjustment, through-hole mounting, PC pin termination)
• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance status provides regulatory advantage over the non-compliant original part
• Cermet resistive material maintains performance specifications within the defined tolerance and temperature coefficient ranges

Physical dimensions show minor variation (approximately 12% reduction in face area), which requires verification against PCB layout constraints and mechanical clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 3362W-1-251LF be used as a direct replacement for the PVC6G251A01B00?

A: Yes, provided that PCB layout accommodates the smaller face dimensions (0.275" x 0.260" versus 0.315" x 0.272"). All electrical parameters and functional characteristics are equivalent.

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

A: Both materials deliver identical electrical performance within the specified tolerance (±10%) and temperature coefficient (±100ppm/°C). Cermet construction in the 3362W series provides enhanced reliability and is used in the active product line.

Q: Does the RoHS compliance difference affect substitution?

A: The 3362W-1-251LF is ROHS3 compliant, whereas the PVC6G251A01B00 is non-compliant. For applications subject to RoHS regulations, the substitute is the required choice. For legacy systems without RoHS requirements, both parts meet the electrical specification.

Q: Are there packaging considerations for procurement?

A: The PVC6G251A01B00 is supplied in bulk packaging, while the 3362W-1-251LF is supplied in tube packaging. Verify that tube packaging is compatible with assembly line equipment and handling procedures.

Q: What inventory status should be considered for production planning?

A: The PVC6G251A01B00 shows 930 pieces in stock but is obsolete with no future availability. The 3362W-1-251LF is active with 998 pieces in stock, supporting both immediate and ongoing procurement requirements.
