PVC6D104A01B00 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The PVC6D104A01B00 is a 100 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material and top adjustment capability. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Active alternatives with comparable electrical specifications and similar form factors are available from both Bourns and TT Electronics/BI Technologies.

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6D104A01B00 is determined by strict equivalence across the following parameters:

Resistance value: 100 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 Turn (exact match required)
Adjustment type: Top Adjustment (exact match required)
Mounting type: Through Hole (exact match required)
Termination style: PC Pins (exact match required)

All substitute parts listed meet these electrical and mechanical criteria. Variations in resistive material (ceramic to cermet), physical dimensions, and product status are noted but do not disqualify substitution eligibility based on functional parameters.

Engineering Selection Recommendations

All listed substitute parts satisfy the electrical and mechanical requirements for direct replacement of the PVC6D104A01B00. Selection among active alternatives should consider the following factors:

Bourns 3362R-1-104LF is the primary direct substitute from the original manufacturer. It maintains Bourns design heritage and is actively produced. ROHS3 compliance and cermet resistive material provide improved environmental performance compared to the obsolete ceramic version.

TT Electronics/BI 25PR100KLF offers active production status with RoHS compliance. The square form factor (0.270" x 0.270") closely matches the original PVC6D dimensions (0.272" x 0.272"), minimizing PCB layout modifications.

TT Electronics/BI 72PR100KLF and 72PMR100KLF are active alternatives with larger square form factors (0.375" x 0.375"), suitable for applications where increased physical size is acceptable or preferred.

TT Electronics/BI 82PR100KLF features a round form factor (0.250" diameter), appropriate for space-constrained designs where circular mounting is advantageous.

All substitute parts carry ROHS3 or RoHS compliance certification, addressing regulatory requirements that the obsolete PVC6D104A01B00 does not meet.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-104LF directly replace the PVC6D104A01B00 in existing designs?

A: Yes. Both parts share identical electrical specifications (100 kΩ, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn top adjustment) and PC pin termination. The primary difference is resistive material (cermet vs. ceramic) and physical dimensions (6.99mm x 6.60mm vs. 6.90mm x 6.90mm), which do not affect functional compatibility in standard applications.

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

A: Both materials meet the specified electrical parameters. Cermet (ceramic-metal composite) offers improved stability and environmental performance, which is why active production parts use this material. The choice between them depends on application-specific requirements not defined by the core electrical specifications.

Q: Are there form factor considerations when selecting a substitute?

A: Yes. The PVC6D104A01B00 has a square face of 6.90mm x 6.90mm. The 3362R-1-104LF (6.99mm x 6.60mm) and 25PR100KLF (6.86mm x 6.86mm) are dimensionally similar. The 72-series parts (9.53mm x 9.53mm square) and 82PR100KLF (6.35mm diameter) have different footprints and may require PCB layout adjustments.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a material composition requirement that does not alter the electrical characteristics specified in this document. All substitute parts maintain the same resistance, power rating, tolerance, and temperature coefficient as the original part.

Q: Which substitute offers the best inventory availability?

A: The 3362R-1-104LF (Bourns) has 7,552 units in stock, the highest among all listed substitutes. The 25PR100KLF has 2,755 units, and the 72PR100KLF has 1,680 units available.
