Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3296W-1-105ALF are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Parameters (Must Match):

• Resistance value: 1 MOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 25

Mechanical Parameters (Must Match):

• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

Compliance Parameters (Must Match):

• RoHS3 Compliant
• REACH Affected status

The substitute parts PV36W105C01B00 and PV36Y105C01B00 meet all electrical, mechanical, and compliance requirements. Differences in packaging format (Tape & Box versus Tube) and minor dimensional variations (within manufacturing tolerance) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with identical RoHS3 and REACH compliance certifications. Selection between the 3296W-1-105ALF and its substitutes should be based on packaging requirements and inventory availability:

• 3296W-1-105ALF (Trimpot® 3296 Series): Tape & Box packaging format. 863 units in stock.
• PV36W105C01B00 (PV36 Series): Tube packaging format. 3265 units in stock.
• PV36Y105C01B00 (PV36 Series): Tube packaging format. 994 units in stock.

All parts are functionally equivalent for circuit applications requiring 1 MOhm, 0.5W, 25-turn cermet trimmer potentiometers with top adjustment and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can PV36W105C01B00 and PV36Y105C01B00 be used interchangeably with 3296W-1-105ALF?

A: Yes. All three parts share identical electrical specifications (1 MOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25 turns), mechanical configuration (top adjustment, cermet material, through-hole mounting, PC pins), and compliance status (RoHS3, REACH). Functional substitution is direct.

Q: What is the difference between the 3296W series and PV36 series?

A: The 3296W belongs to the Trimpot® 3296 sealed series, while PV36W and PV36Y are part of the PV36 series. Both are Bourns Inc. products with equivalent electrical and mechanical parameters for this resistance and power rating. Series designation reflects different product lines within the manufacturer's portfolio.

Q: Does packaging format affect compatibility?

A: Packaging format (Tape & Box versus Tube) affects handling, storage, and automated assembly processes but does not affect electrical or mechanical compatibility. Component selection should account for assembly line requirements and inventory management procedures.

Q: Are dimensional differences significant?

A: The 3296W-1-105ALF has a face dimension of 0.375" x 0.190" (9.53mm x 4.83mm), while PV36W105C01B00 and PV36Y105C01B00 have 0.378" x 0.197" (9.60mm x 5.00mm). These variations fall within standard manufacturing tolerances and do not affect PCB layout compatibility for through-hole applications.

Q: Which part should be selected for new designs?

A: All three parts are active and compliant. Selection should be based on availability, packaging preference, and supply chain strategy. PV36 series parts offer higher inventory levels (3265 and 994 units respectively) compared to 3296W series (863 units).
