Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the 3296X-1-503R is determined by matching the following critical parameters:

• Resistance value: 50 kOhms
• Power rating: 0.5W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 25
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

The substitute parts PV36X503C01B00 and PV36Z503C01B00 meet all electrical and mechanical parameters required for direct substitution. Differences exist only in packaging format (tube versus tape and reel) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products from Bourns Inc. with identical electrical specifications and mechanical compatibility. Selection should be based on the following factors:

3296X-1-503R: Select when tape and reel packaging is required for automated assembly processes. This part is suitable for applications where RoHS non-compliance is acceptable.

PV36X503C01B00: Select when ROHS3 compliance is required and tube packaging is acceptable. This variant offers the highest inventory availability at 2687 units.

PV36Z503C01B00: Select when ROHS3 compliance is required, tube packaging is acceptable, and the PV36X variant is unavailable. This part maintains full electrical and mechanical compatibility.

All parts share identical REACH and ECCN classifications (EAR99) and HTSUS codes (8533.40.8050).

Frequently Asked Questions (FAQ)

Q: Can PV36X503C01B00 or PV36Z503C01B00 be used as direct replacements for 3296X-1-503R?

A: Yes. Both substitute parts meet all electrical parameters (50 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C) and mechanical requirements (25-turn side adjustment, cermet material, through-hole PC pin termination). Dimensional differences are negligible (less than 0.1mm variation).

Q: What is the primary difference between the substitute parts?

A: The main differences are packaging format (tube instead of tape and reel) and RoHS compliance status. Both PV36X503C01B00 and PV36Z503C01B00 are ROHS3 compliant, while 3296X-1-503R is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. All three parts use identical PC pin termination and through-hole mounting. Dimensional variations are within standard manufacturing tolerances and do not affect PCB footprint compatibility.

Q: Which substitute part should be selected for new designs?

A: Selection depends on compliance requirements and packaging preferences. For ROHS3-compliant applications, either PV36X503C01B00 or PV36Z503C01B00 is appropriate. PV36X503C01B00 is recommended due to higher inventory availability.

Q: Do the substitute parts have the same temperature performance?

A: Yes. All three parts share identical temperature coefficient specifications of ±100ppm/°C, ensuring equivalent thermal stability across the operating range.
