TC86P-1-103 Equivalent & Substitute Parts

Part Overview

The TC86P-1-103 is a 10 kOhms trimmer potentiometer manufactured by Bourns Inc., part of the Trimpot® TC86 series. This through-hole component features PC pin termination, cermet resistive material, and 0.3W power rating with top adjustment capability. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

The 3306P-1-103 qualifies as a substitute for the TC86P-1-103 based on the following alignment of critical parameters:

• Resistance value: Both rated at 10 kOhms
• Temperature coefficient: Both ±250ppm/°C
• Number of turns: Both single-turn (1 turn)
• Adjustment type: Both top adjustment
• Resistive material: Both cermet
• Mounting type: Both through hole
• Termination style: Both PC pins
• RoHS compliance: Both ROHS3 compliant
• Moisture sensitivity: Both MSL 1 (Unlimited)

The primary difference is power rating: the substitute operates at 0.2W (1/5W) versus the original 0.3W, with a slightly wider tolerance of ±25% compared to ±20%. Physical dimensions show minor variation (8.10mm x 6.80mm versus 7.70mm x 6.80mm).

Parameter Comparison

Engineering Selection Recommendations

The 3306P-1-103 is an active product from Bourns Inc. and represents the primary substitute for the obsolete TC86P-1-103. Both components maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) and share the same HTSUS code (8533.40.8050), confirming regulatory and tariff equivalence.

The substitute maintains critical electrical parameters: identical resistance value, temperature coefficient, and single-turn adjustment mechanism. The reduced power rating (0.2W versus 0.3W) and slightly wider tolerance (±25% versus ±20%) must be evaluated against circuit requirements. The marginally larger physical footprint (0.4mm width increase) requires verification of PCB layout compatibility.

Selection of the 3306P-1-103 is appropriate for applications where the lower power dissipation is acceptable and board space permits the minor dimensional increase.

Frequently Asked Questions (FAQ)

Q: Can the 3306P-1-103 directly replace the TC86P-1-103 in all applications?

A: Direct replacement is possible when circuit power dissipation requirements do not exceed 0.2W and tolerance specifications can accommodate ±25% variation. Physical dimensions must be verified for PCB layout compatibility due to the 0.4mm width increase.

Q: What is the significance of the power rating difference (0.3W versus 0.2W)?

A: Power rating indicates maximum continuous power dissipation. The substitute's lower rating requires confirmation that actual circuit operating conditions remain below 0.2W to ensure reliable long-term performance.

Q: Are there compliance or certification differences between these parts?

A: Both components are ROHS3 compliant, REACH unaffected, and share identical ECCN and HTSUS classifications. No compliance barriers exist for substitution.

Q: How do tolerance differences affect circuit performance?

A: The TC86P-1-103 specifies ±20% tolerance while the 3306P-1-103 specifies ±25%. Applications requiring tighter resistance accuracy must account for this wider tolerance band in the substitute.

Q: Are PC pin terminations identical between both parts?

A: Both components use PC pin termination style suitable for through-hole PCB mounting. Pin configuration and spacing must be verified against original design documentation.

Q: What is the availability status of each component?

A: The TC86P-1-103 is obsolete with limited remaining inventory. The 3306P-1-103 is an active product with current manufacturing availability, making it the recommended long-term solution for new designs and ongoing production.
