PV37W504C01B00 Equivalent & Substitute Parts

Part Overview

The PV37W504C01B00 is a 500 kOhms, 0.25W through-hole trimmer potentiometer manufactured by Bourns Inc. in the PV37 series. This cermet-based, 12-turn top-adjustment component is designed for precision applications requiring manual resistance tuning in compact form factors. The part maintains Active product status with full RoHS3 compliance and REACH affected designation. Substitute parts are identified when electrical specifications, mechanical mounting characteristics, and regulatory compliance align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PV37W504C01B00 is determined by strict alignment of the following parameters:

• Resistance value: 500 kOhms
• Power rating: 0.25W (1/4W)
• Tolerance: ±10%
• Number of turns: 12
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Product status: Active

The 64WR500KLF from TT Electronics/BI meets all substitution criteria. Minor variations in temperature coefficient (±100ppm/°C vs. ±150ppm/°C) and physical dimensions (0.250" x 0.165" vs. 0.252" x 0.157") remain within acceptable tolerance ranges for equivalent functionality. Both components share identical electrical specifications for resistance, power, tolerance, and turn count.

Parameter Comparison

Engineering Selection Recommendations

Both the PV37W504C01B00 and 64WR500KLF maintain Active product status, ensuring continued availability and manufacturing support. The PV37W504C01B00 carries RoHS3 compliance with REACH affected designation. The 64WR500KLF provides RoHS compliance with REACH unaffected status, offering regulatory flexibility in applications where REACH compliance is a primary consideration.

Selection between these components should be based on:

• Supply chain availability and lead time requirements
• Packaging preference (Bulk vs. Tube)
• Regulatory environment and REACH compliance requirements
• Physical space constraints within the application (dimensional tolerance of ±0.002" to ±0.008")
• Temperature coefficient precision needs (±100ppm/°C vs. ±150ppm/°C)

Both components are electrically and mechanically equivalent for standard 500 kOhms, 0.25W trimmer potentiometer applications.

Frequently Asked Questions (FAQ)

Q: Can the 64WR500KLF directly replace the PV37W504C01B00 in existing designs?

A: Yes. Both components share identical electrical specifications (500 kOhms, 0.25W, ±10% tolerance, 12-turn cermet construction) and mechanical mounting characteristics (through-hole PC pins, top adjustment). Physical dimensions differ by less than 0.01 inches, which is acceptable for standard PCB layouts.

Q: What is the significance of the temperature coefficient difference?

A: The PV37W504C01B00 has a temperature coefficient of ±150ppm/°C, while the 64WR500KLF is ±100ppm/°C. The 64WR500KLF exhibits superior temperature stability. For applications operating across wide temperature ranges or requiring tighter resistance tolerance over temperature, the 64WR500KLF is the preferred choice.

Q: How do packaging differences affect component selection?

A: The PV37W504C01B00 is supplied in Bulk packaging, while the 64WR500KLF is supplied in Tube packaging. Tube packaging provides better component protection during storage and handling. Selection depends on inventory management practices and handling procedures.

Q: Are there compliance differences between these parts?

A: The PV37W504C01B00 is RoHS3 compliant and REACH affected. The 64WR500KLF is RoHS compliant and REACH unaffected. For applications in regions with strict REACH compliance requirements, the 64WR500KLF may be advantageous.

Q: What are the critical parameters for substitution?

A: Substitution is valid when resistance (500 kOhms), power rating (0.25W), tolerance (±10%), turn count (12), adjustment type (top), material (cermet), mounting (through-hole), and termination (PC pins) remain constant. Deviations in any of these parameters disqualify a component as a direct substitute.
