TC89P-1-201 Equivalent & Substitute Parts

Part Overview

The TC89P-1-201 is a 200 Ohm, 0.5W trimmer potentiometer manufactured by Bourns Inc. as part of the Trimpot® TC89 Open Frame series. This through-hole component features PC pin termination, cermet resistive material, and top adjustment capability with a single turn design. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC89P-1-201 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 200 Ohms (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: Rectangular - 0.453" x 0.346" Face / 11.50mm x 8.80mm (exact match required)

The TE Connectivity Passive Product 409HA201M meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 409HA201M from TE Connectivity Passive Product is a direct functional substitute for the obsolete TC89P-1-201. All critical electrical and mechanical parameters match exactly. The 409HA201M offers the additional feature of top and bottom adjustment capability, which provides enhanced flexibility without compromising compatibility with applications designed for top adjustment only.

The 409HA201M is currently in active production status, ensuring long-term availability and supply chain reliability. The part carries RoHS3 compliance equivalent to the original component and maintains the same ECCN and HTSUS classifications, supporting regulatory and procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the 409HA201M be used as a direct replacement for the TC89P-1-201?

A: Yes. The 409HA201M meets all electrical and mechanical specifications of the TC89P-1-201, including resistance value, power rating, tolerance, temperature coefficient, number of turns, resistive material, mounting type, termination style, and physical dimensions.

Q: What is the difference in adjustment capability between these parts?

A: The TC89P-1-201 provides top adjustment only. The 409HA201M provides both top and bottom adjustment. This difference does not prevent substitution; applications requiring top adjustment will function identically with the 409HA201M.

Q: Why is the TC89P-1-201 obsolete?

A: The TC89P-1-201 is listed as obsolete by the manufacturer. The 409HA201M is the active equivalent from TE Connectivity Passive Product and is currently manufactured and stocked.

Q: Are there any compliance or certification differences?

A: The TC89P-1-201 is ROHS3 compliant. The 409HA201M carries RoHS status as not applicable but maintains equivalent ECCN (EAR99) and HTSUS (8533.40.8050) classifications. Both parts are REACH unaffected.

Q: Will the 409HA201M fit in the same PCB footprint?

A: Yes. Both parts share identical physical dimensions of 0.453" x 0.346" face (11.50mm x 8.80mm) and use PC pin through-hole termination, ensuring mechanical and electrical compatibility with existing PCB layouts.
