3386P-1-204TLF Equivalent & Substitute Parts

Part Overview

The 3386P-1-204TLF is a 200 kOhms trimmer potentiometer manufactured by Bourns Inc. in the Trimpot® 3386 series. This sealed through-hole trimmer potentiometer is rated at 0.5W power dissipation with cermet resistive material and top finger adjustment. The part is currently active in production with ROHS3 compliance and is suitable for applications requiring precision resistance adjustment in compact form factors. Substitute parts may be required due to inventory constraints, lead time considerations, or design flexibility across compatible product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386P-1-204TLF is determined by the following critical parameters:

• Resistance Value: 200 kOhms (exact match required)
• Power Rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature Coefficient: ±100ppm/°C or better
• Number of Turns: 1 turn
• Resistive Material: Cermet
• Mounting Type: Through Hole
• Termination Style: PC Pins
• Regulatory Compliance: ROHS3 Compliant

The M63M204KB30T607 from Vishay Spectrol meets all critical electrical and mechanical parameters. The primary difference is the adjustment type (side adjustment versus top finger adjustment) and physical dimensions, which do not affect electrical performance or circuit compatibility when PCB layout accommodates the slightly larger footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386P-1-204TLF and M63M204KB30T607 are active production parts with ROHS3 compliance and EAR99 classification. Selection between these parts should be based on:

1. PCB Layout Compatibility: The M63M204KB30T607 has a slightly larger footprint (10.03mm vs 9.53mm). Verify available board space before substitution.

2. Adjustment Access: The 3386P-1-204TLF provides top finger adjustment, while the M63M204KB30T607 uses side adjustment. Confirm that the application's mechanical design accommodates the adjustment method of the selected part.

3. Electrical Equivalence: Both parts are electrically identical across all specified parameters and will function identically in circuit operation.

4. Regulatory Compliance: Both parts meet ROHS3 requirements and are suitable for applications with equivalent compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the M63M204KB30T607 be used as a direct replacement for the 3386P-1-204TLF?

A: Yes, from an electrical standpoint. Both parts have identical resistance, power rating, tolerance, temperature coefficient, and termination style. However, the adjustment method differs (top versus side), and the physical dimensions are slightly larger. PCB layout and mechanical access must be verified before substitution.

Q: What is the difference between top finger adjustment and side adjustment?

A: Top finger adjustment allows the potentiometer to be tuned from above the PCB, while side adjustment requires access from the side. The choice depends on the application's mechanical design and accessibility requirements during assembly and field adjustment.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are active production components with ROHS3 compliance. Suitability for high-reliability applications depends on specific application requirements beyond the parameters provided.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification indicates the resistance change per degree Celsius across the operating temperature range. Both parts have identical temperature stability, ensuring consistent performance across temperature variations.

Q: Does the slightly larger footprint of the M63M204KB30T607 affect circuit performance?

A: No. The footprint difference does not affect electrical performance. It only impacts PCB layout and mechanical fit. Verify that the application's PCB design accommodates the larger dimensions.
