1208P201 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The 1208P201 is a 200 Ohm, 0.5W wirewound trimmer potentiometer manufactured by Nidec Components Corporation. This through-hole component features PC pin termination, side adjustment, and 16-turn resolution. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1208P201 is determined by the following critical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Adjustment Type: Side Adjustment (exact match required)
• Resistive Material: Wirewound (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pins (exact match required)

The 3005P-1-201 from Bourns Inc. meets all critical substitution criteria. Variations in power rating, number of turns, and physical dimensions are acceptable provided the application circuit can accommodate the substitute component's specifications.

Parameter Comparison

Engineering Selection Recommendations

The 3005P-1-201 (Bourns Trimpot® 3005 - Sealed) is a direct functional substitute for the obsolete 1208P201. Both components are ROHS3 compliant and carry MSL rating 1. The substitute maintains identical electrical specifications for resistance, tolerance, and temperature coefficient.

The 3005P-1-201 offers two design advantages: higher power rating (1W versus 0.5W) and increased turn count (20 versus 16), providing greater adjustment range and finer tuning capability. The substitute's slightly larger face dimension (0.310" x 0.160" versus 0.264" x 0.165") requires verification against PCB layout constraints.

The substitute part is currently in active production status with established supply chain availability, eliminating obsolescence risk associated with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 3005P-1-201 be used as a direct replacement for the 1208P201?

A: Yes. Both components share identical resistance (200 Ohms), tolerance (±10%), temperature coefficient (±50ppm/°C), adjustment type (side adjustment), resistive material (wirewound), mounting type (through hole), and termination style (PC pins). PCB layout must accommodate the substitute's slightly larger dimensions.

Q: What is the significance of the different power ratings (0.5W versus 1W)?

A: The substitute's higher power rating indicates greater thermal dissipation capability. In applications where the original 0.5W component operated within its power budget, the 1W substitute will operate at lower temperature rise, extending component life and improving stability.

Q: Why does the substitute have more turns (20 versus 16)?

A: The increased turn count provides finer adjustment resolution. Applications requiring coarse adjustment benefit from this enhanced tuning capability. The adjustment mechanism remains functionally identical.

Q: Are there packaging differences between these components?

A: The 1208P201 is supplied in standard packaging, while the 3005P-1-201 is supplied in tube packaging. Both components are through-hole mounted with PC pin termination and are suitable for automated assembly processes.

Q: What compliance certifications apply to both components?

A: Both the 1208P201 and 3005P-1-201 are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level). The substitute is REACH affected; the original part's REACH status is vendor undefined.
