Substitute Part Grouping Explanation

Substitute parts for the 3299Z-1-201 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Resistance value: 200 Ohms (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)
• Manufacturer: Bourns Inc. (exact match required)

Two substitute parts meet all electrical and mechanical criteria:

1. 3296Z-1-201 - Trimpot® 3296 series variant with identical electrical specifications but different physical dimensions (0.395" x 0.190" face vs. 0.395" x 0.240" face)
2. 3299Z-1-201LF - Trimpot® 3299 series variant with identical electrical and physical specifications but with RoHS3 compliance certification

Parameter Comparison

Engineering Selection Recommendations

3299Z-1-201LF is the preferred substitute when RoHS3 compliance is required for end-product certification or regulatory requirements. This part maintains identical electrical performance and physical dimensions to the main part number while providing enhanced environmental compliance status. Both the main part and this substitute are from the same Trimpot® 3299 series.

3296Z-1-201 is a functional electrical equivalent suitable for applications where physical space constraints permit a smaller footprint (0.190" vs. 0.240" face height). This part belongs to the Trimpot® 3296 series and maintains all electrical specifications. PCB layout and mechanical mounting considerations must be evaluated before selection, as the reduced height may affect component placement and accessibility.

Both substitute parts maintain active production status and are available in higher inventory quantities than the primary part number, supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3296Z-1-201 be used as a direct replacement for the 3299Z-1-201?

A: The 3296Z-1-201 is electrically equivalent with identical resistance, power rating, tolerance, temperature coefficient, and turn count. However, it has a smaller physical footprint (0.190" vs. 0.240" face height). Direct substitution is possible only if PCB layout and mechanical mounting accommodate the reduced height dimension.

Q: What is the difference between 3299Z-1-201 and 3299Z-1-201LF?

A: Both parts are from the Trimpot® 3299 series with identical electrical specifications and physical dimensions. The primary difference is RoHS compliance status: 3299Z-1-201 is RoHS non-compliant, while 3299Z-1-201LF is RoHS3 compliant. Select 3299Z-1-201LF for applications requiring RoHS certification.

Q: Are all three parts sealed?

A: Yes, all three parts are sealed variants within their respective Trimpot® series (3299 or 3296), providing protection against environmental contamination.

Q: Do these parts have the same packaging?

A: Yes, all three parts are supplied in tube packaging.

Q: What electrical parameters must match for substitution?

A: Substitution requires exact matching of resistance value (200 Ohms), 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), and termination style (PC pins).
