Bourns 3319P-1-202 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3319P-1-202 is a 2 kOhm, 0.2W through-hole trimmer potentiometer with PC pin termination, featuring carbon resistive material and top adjustment capability. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The 1-turn adjustment mechanism and rectangular form factor (11.00mm x 9.00mm) define its application scope in compact circuit board layouts requiring precision resistance adjustment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3319P-1-202 is determined by the following critical parameters:

• Resistance Value: Must be 2 kOhms
• Termination Style: Must be PC Pins for direct PCB mounting compatibility
• Mounting Type: Must be Through Hole
• Adjustment Type: Must be Top Adjustment
• Number of Turns: Must be 1-turn
• Power Rating: Must meet or exceed 0.2W minimum requirement
• Form Factor Compatibility: Physical dimensions must accommodate existing PCB layouts

The TT Electronics/BI 36PR2KLF meets all substitution criteria. While it features Cermet resistive material (versus carbon in the original) and improved specifications (0.3W power rating, ±20% tolerance, ±250ppm/°C temperature coefficient), these represent performance enhancements rather than incompatibilities. The 36PR2KLF maintains identical resistance, termination, mounting, and adjustment characteristics while offering superior environmental stability and power handling.

Engineering Selection Recommendations

The TT Electronics/BI 36PR2KLF is the qualified substitute for the obsolete Bourns 3319P-1-202. Selection is based on:

• Functional Equivalence: Identical resistance value, termination style, mounting type, and adjustment mechanism ensure direct functional replacement in existing circuit designs.
• Compliance Alignment: Both components maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements for new production.
• Active Product Status: The 36PR2KLF is actively manufactured and stocked, eliminating supply chain risk associated with the obsolete 3319P-1-202.
• Performance Enhancement: The substitute provides superior specifications (higher power rating, tighter tolerance, improved temperature stability) without introducing incompatibility.
• Physical Accommodation: The smaller footprint (8.20mm x 6.80mm versus 11.00mm x 9.00mm) requires PCB layout verification to confirm fit within existing mounting holes and clearance zones.

Frequently Asked Questions (FAQ)

Q: Can the 36PR2KLF be used as a direct drop-in replacement for the 3319P-1-202?

A: Electrically and functionally, yes. The 36PR2KLF provides identical resistance, termination, and adjustment characteristics. However, the smaller physical dimensions (8.20mm x 6.80mm versus 11.00mm x 9.00mm) require confirmation that existing PCB mounting holes and component clearances accommodate the substitute without modification.

Q: What is the significance of the resistive material difference (Carbon versus Cermet)?

A: Cermet material in the 36PR2KLF provides superior temperature stability (±250ppm/°C versus ±1000ppm/°C) and improved power handling (0.3W versus 0.2W). This represents a performance upgrade with no negative impact on circuit compatibility.

Q: Are both components RoHS compliant?

A: Yes. The 3319P-1-202 is ROHS3 compliant, and the 36PR2KLF is RoHS compliant. Both satisfy regulatory requirements for electronic component manufacturing and use.

Q: What tolerance difference exists between these components?

A: The 3319P-1-202 has ±25% tolerance, while the 36PR2KLF has ±20% tolerance. The tighter tolerance of the substitute provides improved resistance accuracy without affecting circuit compatibility.

Q: Is the 36PR2KLF currently available?

A: Yes. The 36PR2KLF is classified as active product status with documented inventory availability, ensuring reliable procurement for new designs and production runs.
