Substitute Part Grouping Explanation

Substitute parts for the 3299P-1-201 are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (Same Series, Enhanced Compliance): The 3299P-1-201LF maintains identical electrical specifications (200 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C, 25-turn side adjustment, cermet material, through-hole PC pins) and physical dimensions (0.240" x 0.375" face). The primary distinction is RoHS3 compliance certification, making this part suitable for applications requiring enhanced environmental compliance. Both parts belong to the Trimpot® 3299 sealed series.

Similar Alternative (Different Series, Dimensional Variation): The PV36P201C01B00 provides electrical equivalence across all critical parameters (200 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C, 25-turn side adjustment, cermet material, through-hole PC pins) but belongs to the PV36 series with different physical dimensions (0.378" x 0.197" face versus 0.240" x 0.375"). This part is RoHS3 compliant and suitable for applications where the alternative footprint is acceptable.

Critical Substitution Parameters:

• Resistance value and tolerance
• Power rating and temperature coefficient
• Number of turns and adjustment type
• Resistive material composition
• Mounting type and termination style
• Physical dimensions (for PCB layout compatibility)

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select 3299P-1-201LF when designs mandate ROHS3 certification. This part provides identical electrical and mechanical specifications to the primary 3299P-1-201 with enhanced environmental compliance documentation. Both parts maintain the same Trimpot® 3299 sealed series design and identical physical footprint.

For Alternative Footprint Applications: Select PV36P201C01B00 when PCB layout constraints require the smaller 0.378" x 0.197" face dimension instead of the standard 0.240" x 0.375" format. This part maintains all electrical equivalence and includes ROHS3 compliance. Verify PCB hole spacing and mounting clearances before substitution.

For Non-Compliance Applications: The 3299P-1-201 remains suitable for applications where RoHS3 compliance is not required. All three parts are active production items with stable inventory levels.

Frequently Asked Questions (FAQ)

Q: Can 3299P-1-201LF be used as a direct replacement for 3299P-1-201? A: Yes. Both parts share identical electrical specifications (200 Ohms, 0.5W, ±10%, ±100ppm/°C, 25-turn side adjustment, cermet material) and physical dimensions (0.240" x 0.375" face). The primary difference is RoHS3 compliance certification on the LF variant. No circuit redesign or PCB modification is required.

Q: What are the dimensional differences between 3299P-1-201 and PV36P201C01B00? A: The 3299P-1-201 has a face dimension of 0.240" x 0.375" (6.10mm x 9.53mm), while the PV36P201C01B00 measures 0.378" x 0.197" (9.60mm x 5.00mm). Verify PCB hole spacing and mounting clearances before substitution. All other electrical parameters remain equivalent.

Q: Are all three parts electrically interchangeable? A: Yes, for circuit functionality. All three parts provide 200 Ohms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn side adjustment, and cermet resistive material. Physical footprint differences must be evaluated for PCB compatibility.

Q: Which part should be selected for new designs? A: For new designs, 3299P-1-201LF is recommended due to ROHS3 compliance and identical specifications to the primary part. For applications with specific footprint requirements, evaluate PV36P201C01B00 based on PCB layout constraints.

Q: Do all parts share the same packaging? A: Yes. All three parts are supplied in tube packaging and maintain the same through-hole PC pin termination style.
