Substitute Part Grouping Explanation

Substitution eligibility for the 3296P-1-105 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 1 MOhms (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: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

Two substitute parts meet these criteria: the 3296P-1-105LF (direct variant within the same Trimpot® 3296 series) and the PV36P105C01B00 (equivalent from the PV36 series). Both maintain identical electrical specifications and functional performance while differing in compliance status and minor dimensional tolerances.

Parameter Comparison

Engineering Selection Recommendations

The 3296P-1-105LF serves as the direct substitute within the Trimpot® 3296 Sealed series. It maintains identical electrical and mechanical specifications while offering ROHS3 compliance, addressing regulatory requirements in applications subject to RoHS directives. This variant is recommended when compliance certification is a project requirement.

The PV36P105C01B00 represents a cross-series equivalent from the PV36 product line. It delivers identical electrical performance and ROHS3 compliance with a minor dimensional variation (0.378" x 0.197" versus 0.375" x 0.190" face dimensions). This part is suitable for applications where the PV36 series footprint is acceptable and higher inventory availability is advantageous.

Selection between these substitutes depends on compliance obligations, PCB layout constraints, and inventory requirements. All three parts are active products from Bourns Inc. with confirmed stock availability.

Frequently Asked Questions (FAQ)

Q: Can the 3296P-1-105LF be used as a direct replacement for the 3296P-1-105?

A: Yes. The 3296P-1-105LF is electrically and mechanically equivalent. The primary difference is RoHS3 compliance status. Both parts share identical resistance, power rating, tolerance, temperature coefficient, turn count, adjustment mechanism, and termination style.

Q: What is the difference between the 3296P-1-105 and PV36P105C01B00?

A: Both parts are functionally equivalent with identical electrical specifications. The PV36P105C01B00 belongs to the PV36 series and has a slightly larger face dimension (0.378" x 0.197" versus 0.375" x 0.190"). This dimensional difference may affect PCB layout compatibility. Both are ROHS3 compliant.

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

A: Compatibility is maintained across all three parts for electrical function. The only consideration is the dimensional tolerance between the Trimpot® 3296 series (0.375" x 0.190") and the PV36 series (0.378" x 0.197"). Verify PCB footprint and mounting hole spacing before selecting the PV36P105C01B00.

Q: Which substitute should I choose if RoHS compliance is required?

A: Both the 3296P-1-105LF and PV36P105C01B00 are ROHS3 compliant. The 3296P-1-105LF is recommended if you require the same series designation and identical dimensions. The PV36P105C01B00 is an alternative if cross-series compatibility is acceptable.

Q: Is inventory availability a factor in part selection?

A: Yes. Current stock levels are 887 units (3296P-1-105), 1052 units (3296P-1-105LF), and 1235 units (PV36P105C01B00). If supply continuity is critical, the PV36P105C01B00 offers the highest available inventory.
