82PAR2KLF Equivalent & Substitute Parts

Part Overview

The 82PAR2KLF is a 2 kOhm, 0.5W through-hole trimmer potentiometer manufactured by TT Electronics/BI. This cermet-based side-adjustment component features PC pin termination and is designed for applications requiring precision variable resistance in compact rectangular form factors. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 82PAR2KLF is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (2 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must match exactly
• Functional Design: Single-turn (1 turn) side-adjustment mechanism with cermet resistive element
• Physical Interface: Through-hole mounting with PC pin termination
• Regulatory Compliance: ROHS3 compliance required

The 3329W-1-202LF from Bourns Inc. meets all substitution criteria across these parameters, establishing it as a direct functional equivalent despite differences in physical dimensions and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The 3329W-1-202LF is the qualified substitute for the obsolete 82PAR2KLF based on:

• Electrical Equivalence: Identical resistance, power rating, tolerance, and temperature coefficient specifications ensure functional interchangeability in circuit applications
• Active Product Status: The Bourns 3329W-1-202LF maintains active manufacturing status, ensuring long-term availability and supply chain reliability
• Regulatory Alignment: Both components maintain ROHS3 compliance, supporting continued use in regulated applications
• Physical Interface Compatibility: Matching through-hole mounting and PC pin termination enable direct board-level substitution

Physical dimension differences (face size) require verification of available PCB layout space during integration. The substitute component's slightly different rectangular profile may necessitate minor mechanical accommodation in confined mounting areas.

Frequently Asked Questions (FAQ)

Q: Can the 3329W-1-202LF replace the 82PAR2KLF in existing circuit designs?

A: Yes. The electrical specifications, functional design, and termination interface are identical. Physical dimensions differ slightly; confirm available PCB space accommodates the 0.260" x 0.330" face dimension of the substitute.

Q: Are there differences in adjustment mechanism between these components?

A: No. Both components feature single-turn side adjustment with cermet resistive elements, providing equivalent tuning characteristics and mechanical operation.

Q: What is the significance of the product status difference?

A: The 82PAR2KLF is obsolete and no longer manufactured. The 3329W-1-202LF is actively produced by Bourns, ensuring availability for new procurement and ongoing system support.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both are ROHS3 compliant. The 3329W-1-202LF is REACH Affected, while the original part is REACH Unaffected; verify REACH compliance requirements for your specific application jurisdiction.

Q: What packaging format is the substitute available in?

A: The 3329W-1-202LF is supplied in tube packaging. Confirm packaging compatibility with your procurement and assembly processes.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both components specify ±10% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent performance stability across operating temperature ranges.
