PVC6H203C01B00 Equivalent & Substitute Parts

Part Overview

The PVC6H203C01B00 is a 20 kOhms 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 equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates with ±10% tolerance and ±100ppm/°C temperature coefficient across a single turn adjustment range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6H203C01B00 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 20 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 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Two substitute parts meet these criteria: the 3362X-1-203LF (direct manufacturer equivalent from Bourns Inc.) and the 72XR20KLF (equivalent from TT Electronics / BI Technologies). Both parts satisfy all electrical specifications and compliance requirements. Physical dimensions vary between models, requiring PCB layout verification during substitution.

Parameter Comparison

Engineering Selection Recommendations

The 3362X-1-203LF is the primary substitute for the obsolete PVC6H203C01B00. Both components are manufactured by Bourns Inc., ensuring design continuity and performance equivalence. The 3362X-1-203LF maintains active product status and carries ROHS3 compliance. The primary consideration is the reduced face dimension (6.99mm x 6.60mm versus 8.00mm x 6.90mm), which may provide layout advantages in space-constrained applications.

The 72XR20KLF from TT Electronics / BI Technologies is an alternative substitute meeting all electrical specifications and ROHS3 compliance. This part features a larger square footprint (9.53mm x 9.53mm), which may require PCB layout modification. The 72XR20KLF maintains REACH Unaffected status, matching the original part's regulatory profile.

Both substitute parts employ cermet resistive material compared to the ceramic material in the original PVC6H203C01B00. This material difference does not affect electrical performance within the specified tolerance and temperature coefficient ranges.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-203LF directly replace the PVC6H203C01B00 without PCB modification?

A: The 3362X-1-203LF meets all electrical specifications and maintains the same rectangular orientation. However, the reduced face dimension (6.99mm x 6.60mm versus 8.00mm x 6.90mm) requires verification of PCB pad spacing and mounting hole alignment. Physical layout review is necessary before implementation.

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

A: Both materials satisfy the specified tolerance (±10%) and temperature coefficient (±100ppm/°C) for this application. The material difference does not affect electrical performance within the defined operating parameters.

Q: Is the 72XR20KLF suitable for applications with space constraints?

A: The 72XR20KLF features a larger square footprint (9.53mm x 9.53mm) compared to the original rectangular design (8.00mm x 6.90mm). This part is suitable only for applications where the increased footprint does not conflict with PCB layout requirements.

Q: What are the compliance differences between the substitute parts?

A: The 3362X-1-203LF carries REACH Affected status, while the original PVC6H203C01B00 and 72XR20KLF are REACH Unaffected. All three parts maintain ROHS3 compliance. Regulatory requirements for your application determine which substitute is appropriate.

Q: Are there inventory considerations when selecting a substitute?

A: The 3362X-1-203LF has 1204 units in stock, and the 72XR20KLF has 3852 units in stock. Both exceed typical procurement volumes for active production. Selection should prioritize electrical equivalence and compliance requirements over inventory availability.
