TC89P-1-102 Equivalent & Substitute Parts

Part Overview

The TC89P-1-102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. as part of the Trimpot® TC89 series. This component features cermet resistive material, PC pin termination, and top adjustment capability with a single turn design. 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 eligibility for the TC89P-1-102 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±20%
• Temperature coefficient: ±250ppm/°C
• Number of turns: 1
• Resistive material: Cermet
• Mounting type: Through hole
• Termination style: PC pins
• Physical dimensions: Rectangular - 0.453" x 0.346" Face (11.50mm x 8.80mm)
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute parts meet all these core electrical and mechanical parameters. Adjustment type (top vs. top and bottom) represents a functional enhancement in substitute options and does not prevent substitution, as top adjustment capability is retained in all alternatives.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the TC89P-1-102, the 409HA102M represents the primary substitute option. This part is currently active in production, ensuring long-term availability and supply chain continuity. It meets all electrical and mechanical specifications of the original component while offering enhanced adjustment capability (top and bottom adjustment vs. top adjustment only). The 409HA102M carries RoHS compliance status designation of "Not applicable," which may require evaluation against specific regulatory requirements of the end application.

The 409HS102M serves as a secondary substitute option. While electrically and mechanically equivalent to the TC89P-1-102, this part shares obsolete product status with the original component. However, it is currently available in inventory (3908 pcs) and maintains ROHS3 compliance certification, matching the regulatory posture of the original part.

Selection between 409HA102M and 409HS102M should be based on application-specific regulatory compliance requirements and long-term supply availability needs.

Frequently Asked Questions (FAQ)

Q: Can the 409HA102M or 409HS102M be used as direct replacements for the TC89P-1-102?

A: Yes. Both substitute parts meet all critical electrical parameters (1 kOhm resistance, 0.5W power rating, ±20% tolerance, ±250ppm/°C temperature coefficient) and mechanical specifications (through-hole mounting, PC pin termination, identical physical dimensions, cermet material). The adjustment type enhancement (top and bottom vs. top only) does not prevent substitution.

Q: What is the difference between the two substitute options?

A: The 409HA102M is currently in active production status, while the 409HS102M is obsolete. Both are electrically and mechanically identical. The 409HA102M is recommended for new designs and long-term applications requiring supply continuity.

Q: Are there compliance differences between the substitute parts?

A: The TC89P-1-102 and 409HS102M are both ROHS3 compliant. The 409HA102M carries "Not applicable" RoHS status. Applications subject to RoHS regulations should verify compliance requirements before selection.

Q: Do the substitute parts have the same physical footprint?

A: Yes. All three parts share identical dimensions: 0.453" x 0.346" face (11.50mm x 8.80mm). PCB layout and mechanical mounting are directly compatible.

Q: What is the moisture sensitivity level for these components?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
