TC89P-1-202 Equivalent & Substitute Parts

Part Overview

The TC89P-1-202 is a 2 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. as part of the Trimpot® TC89 Open Frame series. This component features cermet resistive material, PC pin termination, and top adjustment capability with a single turn of adjustment. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC89P-1-202 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: ±250ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Physical dimensions: 11.50mm x 8.80mm face (exact match required)

The TE Connectivity 409HA202M meets all critical electrical and mechanical parameters. The primary difference is adjustment capability: the TC89P-1-202 provides top adjustment only, while the 409HA202M provides both top and bottom adjustment. This difference does not affect electrical performance or physical compatibility in applications where only one adjustment axis is utilized.

Parameter Comparison

Engineering Selection Recommendations

The 409HA202M from TE Connectivity Passive Product is a direct functional equivalent for the obsolete TC89P-1-202. Both components are ROHS3 compliant and carry MSL rating 1, meeting identical environmental and regulatory requirements. The 409HA202M maintains active product status, ensuring continued availability and supply chain reliability.

The 409HA202M is suitable for direct substitution in applications currently using the TC89P-1-202. The addition of bottom adjustment capability in the substitute part does not introduce incompatibility; applications requiring single-axis adjustment will function identically to the original design.

Frequently Asked Questions (FAQ)

Q: Can the 409HA202M be used as a direct replacement for the TC89P-1-202?

A: Yes. Both components share identical electrical specifications (2 kOhms, 0.5W, ±20% tolerance, ±250ppm/°C temperature coefficient), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical dimensions (11.50mm x 8.80mm). The 409HA202M provides additional adjustment capability (top and bottom) without affecting electrical performance or physical fit.

Q: What is the significance of the adjustment type difference?

A: The TC89P-1-202 provides top adjustment only, while the 409HA202M provides both top and bottom adjustment. This difference does not affect electrical characteristics or mechanical compatibility. Applications using only one adjustment axis will operate identically with either component.

Q: Are both components RoHS compliant?

A: Yes. Both the TC89P-1-202 and 409HA202M are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the availability status of each component?

A: The TC89P-1-202 is obsolete. The 409HA202M is active and maintains current production status, ensuring ongoing availability for new designs and replacement applications.

Q: Are the physical dimensions identical?

A: Yes. Both components have a rectangular face dimension of 0.453" x 0.346" (11.50mm x 8.80mm), ensuring identical PCB footprint and mounting compatibility.
