PVC6H203A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6H203A01B00 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 part is classified as obsolete, making equivalent substitutes 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 is determined by matching the following critical parameters: resistance value (20 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (side adjustment), mounting type (through hole), and termination style (PC pins).

The substitute parts identified maintain electrical equivalence across all specified parameters. Physical dimensions and resistive material composition (ceramic versus cermet) represent secondary considerations that do not affect electrical functionality within the defined operating parameters. Product status and compliance certifications are documented to support engineering selection decisions.

Parameter Comparison

Engineering Selection Recommendations

The PVC6H203A01B00 is obsolete and no longer in active production. Both substitute parts maintain electrical equivalence and are classified as active products with current manufacturing support.

The 3362X-1-203LF (Bourns Trimpot® 3362 - Sealed series) is ROHS3 compliant and REACH affected. This part offers the closest dimensional profile to the original, with a rectangular face measuring 6.99mm x 6.60mm. The cermet resistive material provides enhanced stability compared to ceramic construction.

The 72XR20KLF (TT Electronics / BI Technologies 72 series) is ROHS3 compliant and REACH unaffected. This part features a larger square face dimension of 9.53mm x 9.53mm and cermet resistive material. Physical space constraints on the PCB should be evaluated when considering this option.

Both substitutes satisfy all electrical parameters and are suitable for applications requiring RoHS compliance. Selection between the two should be based on available PCB space and regulatory requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-203LF directly replace the PVC6H203A01B00?

A: Yes. Both parts maintain identical electrical specifications: 20 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, through-hole mounting, and PC pin termination. The 3362X-1-203LF uses cermet resistive material versus ceramic in the original, which does not affect electrical performance within specified parameters. Physical dimensions differ slightly (6.99mm x 6.60mm versus 8.00mm x 6.90mm), requiring PCB layout verification.

Q: Can the 72XR20KLF directly replace the PVC6H203A01B00?

A: Yes. All electrical parameters are identical. The 72XR20KLF features a larger square face dimension (9.53mm x 9.53mm) compared to the original rectangular profile (8.00mm x 6.90mm). PCB space availability must be confirmed before implementation.

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 construction, used in both substitute parts, provides enhanced temperature stability and reliability in sealed designs. The choice between materials does not affect electrical equivalence for the defined operating parameters.

Q: Are there compliance differences between the substitute parts?

A: The 3362X-1-203LF is REACH affected, while the 72XR20KLF is REACH unaffected. Both are ROHS3 compliant. The original PVC6H203A01B00 is RoHS non-compliant. Regulatory requirements for the end application should guide selection between the two active substitutes.

Q: What packaging formats are available for these substitutes?

A: The 3362X-1-203LF is supplied in tube packaging. The 72XR20KLF is supplied in bulk packaging. Procurement and assembly process requirements should be considered when selecting between these options.
