PVC6E501C01B00 Equivalent & Substitute Parts

Part Overview

The PVC6E501C01B00 is a 500 Ohm, 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. Active alternatives with compatible electrical and mechanical specifications are available from Bourns Inc. and TT Electronics/BI.

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6E501C01B00 is determined by the following mandatory parameters:

Resistance value: 500 Ohms
Power rating: 0.5W (1/2W)
Tolerance: ±10%
Temperature coefficient: ±100ppm/°C
Number of turns: 1
Adjustment type: Side Adjustment
Mounting type: Through Hole
Termination style: PC Pins
RoHS3 compliance

All substitute parts listed meet these core electrical and mechanical requirements. Variations in resistive material (ceramic to cermet), physical dimensions, and product status are noted but do not prevent functional substitution within the specified parameter envelope.

Engineering Selection Recommendations

All three substitute parts (3362S-1-501LF, 3362W-1-501LF, and 72XR500LF) satisfy the electrical parameter requirements of the PVC6E501C01B00. Selection should be based on the following factors:

Bourns Inc. Substitutes (3362S-1-501LF and 3362W-1-501LF): Both are active products from the original manufacturer with ROHS3 compliance. These parts feature smaller physical dimensions (6.99mm x 6.60mm) compared to the original part, which may require PCB layout verification for through-hole mounting clearance. Both use cermet resistive material instead of ceramic, providing improved stability characteristics.

TT Electronics/BI Substitute (72XR500LF): This active product offers ROHS3 compliance with REACH unaffected status. The larger square footprint (9.53mm x 9.53mm) may require PCB layout adjustment. This option provides supply diversity from an alternative manufacturer.

Dimensional compatibility with existing PCB designs is the primary consideration when selecting among these substitutes.

Frequently Asked Questions (FAQ)

Q: Can the PVC6E501C01B00 be directly replaced with 3362S-1-501LF or 3362W-1-501LF?

A: Yes, from an electrical standpoint. Both parts meet all specified electrical parameters (500 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, side adjustment, through-hole mounting, PC pins). However, the smaller physical dimensions (6.99mm x 6.60mm versus 8.00mm x 6.90mm) require verification that the PCB layout accommodates the reduced footprint.

Q: What is the difference between the 3362S-1-501LF and 3362W-1-501LF?

A: Both parts are electrically and mechanically identical. The difference lies in the base product number designation (3362S versus 3362W), which may reflect internal Bourns classification. Electrical specifications, dimensions, and performance characteristics are equivalent.

Q: Why does the 72XR500LF have a larger footprint?

A: The 72XR500LF is manufactured by TT Electronics/BI and uses a square form factor (9.53mm x 9.53mm) compared to the rectangular designs of the Bourns alternatives. This larger footprint is inherent to the 72 series design but does not affect electrical compatibility.

Q: Are there compliance differences between these substitutes?

A: All substitutes are ROHS3 compliant. The 3362S-1-501LF and 3362W-1-501LF are REACH affected, while the 72XR500LF is REACH unaffected. The PVC6E501C01B00 is REACH unaffected. For applications with REACH compliance requirements, the 72XR500LF is the preferred substitute.

Q: What changed from ceramic to cermet resistive material in the substitutes?

A: The substitute parts use cermet (ceramic-metal composite) instead of ceramic. This material change is within the allowed parameter envelope and does not affect the specified electrical characteristics (resistance, tolerance, temperature coefficient, power rating).

Q: Can I use these substitutes in new designs?

A: Yes. The 3362S-1-501LF, 3362W-1-501LF, and 72XR500LF are all active products suitable for new designs. The PVC6E501C01B00 is obsolete and should not be used in new designs.
