Equivalent & Substitute Parts for 3296W-1-502ALF

Part Overview

The 3296W-1-502ALF is a 5 kOhm, 0.5W through-hole trimmer potentiometer from Bourns Inc.'s Trimpot® 3296 series. This sealed cermet trimmer features 25-turn top adjustment with PC pin termination and is designed for precision applications requiring manual resistance calibration. The part maintains active product status and is ROHS3 compliant. Alternative models may be required due to packaging constraints, inventory availability, or specific mechanical fit requirements in legacy or space-constrained designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3296W-1-502ALF is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 25 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The identified substitute parts PV36W502C01B00 and PV36Y502C01B00 meet all electrical and mechanical equivalence criteria. Differences in packaging format (Tube vs. Tape & Box) and minor dimensional variations within tolerance do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3296W-1-502ALF, PV36W502C01B00, and PV36Y502C01B00—are functionally equivalent for applications requiring a 5 kOhm, 0.5W cermet trimmer potentiometer with 25-turn top adjustment and PC pin termination. Selection between these parts should be based on:

• Packaging requirements: The 3296W-1-502ALF is supplied in Tape & Box format, while PV36W502C01B00 and PV36Y502C01B00 are supplied in Tube packaging.
• Inventory availability: PV36W502C01B00 offers the highest stock level at 2408 units.
• Mechanical fit: Minor dimensional differences (approximately 0.003" to 0.007" variation in face dimensions) fall within standard manufacturing tolerances and do not affect PCB mounting or functional performance.
• Regulatory compliance: All parts maintain ROHS3 compliance and REACH affected status, suitable for applications subject to these regulations.

Frequently Asked Questions (FAQ)

Q: Can PV36W502C01B00 or PV36Y502C01B00 be used as direct replacements for 3296W-1-502ALF?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters—resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style—are identical. Packaging format differences do not affect functional interchangeability.

Q: What is the difference between PV36W502C01B00 and PV36Y502C01B00?

A: Both parts are electrically identical with matching specifications. The primary difference is the Moisture Sensitivity Level (MSL): PV36W502C01B00 has MSL not applicable, while PV36Y502C01B00 has MSL 1 (Unlimited). This distinction affects storage and handling requirements but does not impact electrical performance or circuit functionality.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Face dimensions vary slightly between the 3296W-1-502ALF (0.375" x 0.190") and the PV36 series (0.378" x 0.197"). These differences are within standard manufacturing tolerances and do not affect PCB mounting hole spacing or functional performance in standard through-hole applications.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant, REACH affected, classified as EAR99, and share the same HTSUS code (8533.40.8050). They are suitable for applications subject to these regulatory frameworks.

Q: Which part should be selected based on inventory availability?

A: PV36W502C01B00 offers the highest inventory level at 2408 units, followed by PV36Y502C01B00 at 1900 units, and 3296W-1-502ALF at 941 units. Selection should align with procurement lead time and supply chain requirements.
