Substitute Part Grouping Explanation

Substitution eligibility for the 3296P-1-505 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria must be met for a part to serve as a direct substitute:

• Resistance value: 5 MOhms (exact match)
• Power rating: 0.5W / 1/2W (exact match)
• Tolerance: ±10% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Number of turns: 25 (exact match)
• Adjustment type: Side Adjustment (exact match)
• Resistive material: Cermet (exact match)
• Mounting type: Through Hole (exact match)
• Termination style: PC Pins (exact match)
• Physical dimensions: Rectangular - 0.375" x 0.190" Face (exact match)
• Series: Trimpot® 3296 - Sealed (exact match)

The 3296P-1-505LF meets all substitution criteria and differs only in RoHS compliance status, making it a valid direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 3296P-1-505LF is a direct functional equivalent to the 3296P-1-505. Both parts maintain identical electrical performance and mechanical compatibility. The primary distinction is RoHS3 compliance status of the 3296P-1-505LF, which makes it the preferred selection for applications subject to RoHS directives or customer specifications requiring lead-free termination. Both parts carry Active product status and are manufactured by Bourns Inc. under the same Trimpot® 3296 sealed series designation. Selection between these parts should be based on regulatory and compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the 3296P-1-505LF replace the 3296P-1-505 in existing designs?

A: Yes. The 3296P-1-505LF is electrically and mechanically identical to the 3296P-1-505. Both parts share the same resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment mechanism, resistive material, mounting type, termination style, and physical dimensions. Direct substitution is possible without circuit or layout modifications.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance. The 3296P-1-505 is RoHS non-compliant, while the 3296P-1-505LF is ROHS3 compliant. All other specifications are identical.

Q: Which part should I specify for new designs?

A: Specify the 3296P-1-505LF for new designs unless legacy compatibility with the non-compliant version is explicitly required. The LF variant provides RoHS3 compliance while maintaining full electrical and mechanical equivalence.

Q: Are there any package or inventory considerations?

A: Both parts are supplied in tube packaging. The 3296P-1-505 has 833 units in stock, while the 3296P-1-505LF has 1314 units in stock. Availability should be confirmed with your supplier for production quantities.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. The identical through-hole PC pin termination, rectangular form factor (0.375" x 0.190" face), and mounting type ensure mechanical and electrical interchangeability on the same PCB without any modifications to footprints or assembly procedures.
