PVC6H502A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6H502A01B00 is a 5 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. in the PVC6 series. This component features ceramic resistive material, side adjustment capability, and PC pin termination for printed circuit board mounting. The product is currently obsolete, making equivalent substitutes necessary for ongoing design requirements and production needs.

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6H502A01B00 is determined by matching the following critical parameters:

• Resistance value: 5 kOhms
• 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

The substitute parts listed below meet all these core electrical and mechanical requirements. Variations in resistive material (ceramic to cermet), physical dimensions, and compliance certifications do not affect functional substitutability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both 3362X-1-502LF and 25SR5KLF are functionally equivalent to the obsolete PVC6H502A01B00 based on electrical and mechanical parameters. Selection between these substitutes should consider the following factors:

3362X-1-502LF (Bourns Trimpot® 3362 - Sealed): This part maintains Bourns manufacturing continuity and is ROHS3 compliant. It is suitable for applications requiring modern regulatory compliance. The sealed design provides enhanced environmental protection. Physical dimensions are slightly smaller than the original part.

25SR5KLF (TT Electronics/BI Series 25): This part is RoHS compliant and REACH unaffected. It offers a square footprint geometry, which may provide different PCB layout advantages compared to the rectangular form factor of the original part. Physical dimensions are comparable to the 3362X-1-502LF variant.

Both substitutes are currently in active production with confirmed inventory availability, ensuring supply chain continuity for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3362X-1-502LF directly replace the PVC6H502A01B00 in existing designs?

A: Yes. The 3362X-1-502LF meets all specified electrical parameters (5 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, side adjustment, through-hole PC pins). Physical dimensions are slightly smaller, but the component will function identically in the circuit. PCB layout verification is recommended to confirm fit within the allocated space.

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 (ceramic-metal composite) offers improved stability and environmental resistance compared to ceramic. The substitute parts use cermet material, which provides enhanced performance characteristics while maintaining electrical equivalence.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 3362X-1-502LF is ROHS3 compliant and REACH affected. The 25SR5KLF is RoHS compliant and REACH unaffected. The original PVC6H502A01B00 is RoHS non-compliant. Selection should align with your product's regulatory requirements.

Q: Do the physical dimension differences affect PCB compatibility?

A: The substitute parts have smaller footprints than the original PVC6H502A01B00. The 3362X-1-502LF measures 0.275" x 0.260" (6.99mm x 6.60mm), and the 25SR5KLF measures 0.270" x 0.270" (6.86mm x 6.86mm), compared to the original 0.315" x 0.272" (8.00mm x 6.90mm). Verify that the reduced dimensions are compatible with your PCB layout and mounting requirements.

Q: Which substitute should I select for new production designs?

A: Both parts are suitable for new designs. The 3362X-1-502LF provides Bourns continuity and ROHS3 compliance. The 25SR5KLF offers an alternative source and REACH unaffected status. Selection depends on your specific regulatory, sourcing, and layout requirements.
