Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3292P-1-203 is determined by the following critical parameters:

• Electrical Parameters: Resistance value (20 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must match exactly
• Mechanical Parameters: Number of turns (25), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins) must be identical
• Form Factor: Rectangular package dimensions must accommodate the original footprint or be compatible with the application layout

The PV36P203C01B00 meets all electrical and mechanical criteria for substitution. Both parts share identical resistance, power rating, tolerance, temperature coefficient, turn count, adjustment mechanism, material composition, and termination style. Dimensional variation (9.53mm x 3.81mm versus 9.60mm x 5.00mm) represents a minor increase in face dimensions that does not affect electrical performance or standard PCB mounting compatibility.

Engineering Selection Recommendations

3292P-1-203 is the primary selection when RoHS non-compliant components are acceptable for the application. This part is actively stocked with 997 units available.

PV36P203C01B00 is the recommended substitute when ROHS3 compliance is required. This part offers superior regulatory compliance status and higher inventory availability (2886 units). The minor dimensional increase (0.003" width, 0.047" height) is within typical PCB layout tolerances for through-hole components and does not compromise electrical performance or standard mounting practices.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications and are REACH Affected. Selection between these parts should be based on regulatory requirements and available inventory for your supply chain.

Frequently Asked Questions (FAQ)

Q: Can PV36P203C01B00 replace 3292P-1-203 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, power rating, tolerance, temperature coefficient, turn count, adjustment type, and termination style. The face dimension increase (0.003" x 0.047") is minor and compatible with standard through-hole PCB layouts. Verify that the slightly larger footprint does not conflict with component placement constraints in your specific application.

Q: What is the primary difference between these two parts?

A: The PV36P203C01B00 is ROHS3 compliant, while the 3292P-1-203 is RoHS non-compliant. All electrical and mechanical specifications are identical. The PV36 series also offers higher inventory availability.

Q: Are the PC pin terminations identical between both parts?

A: Yes. Both parts use PC pin termination style suitable for through-hole soldering to standard PCB layouts. No modification to existing solder pads or assembly procedures is required.

Q: Does the dimensional difference affect circuit performance?

A: No. The face dimension variation does not affect electrical performance, resistance accuracy, temperature stability, or adjustment characteristics. Both parts deliver identical functional performance in circuit applications.

Q: Which part should I specify for new designs?

A: Specify PV36P203C01B00 for new designs requiring ROHS3 compliance. For legacy designs or applications without RoHS requirements, either part is acceptable based on inventory and delivery considerations.
