Nidec 1113T201 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Nidec Components Corporation 1113T201 is a 200 Ohm, 0.75W wirewound trimmer potentiometer with PC pin termination and top adjustment capability. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The 1-turn adjustment design and through-hole mounting configuration are standard for legacy control circuit implementations requiring precision resistance adjustment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1113T201 is determined by the following critical parameters that must remain constant or compatible:

• Resistance Value: 200 Ohms (exact match required)
• Termination Style: PC Pins (mechanical and electrical interface requirement)
• Adjustment Type: Top Adjustment (functional interface requirement)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Resistive Material: Wirewound (performance and stability characteristics)
• Number of Turns: 1 Turn (adjustment range and resolution)
• Temperature Coefficient: ±50ppm/°C (thermal stability requirement)

The Bourns 3345P-1-201 qualifies as a substitute based on matching all critical parameters. Secondary parameters including power rating, tolerance, physical dimensions, and compliance certifications may vary within acceptable engineering margins for component substitution.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 3345P-1-201 is suitable for direct substitution of the obsolete Nidec 1113T201 based on the following engineering criteria:

Compliance & Availability: The Bourns component maintains ROHS3 compliance and active product status, ensuring long-term availability and regulatory alignment. The Nidec part's obsolete status necessitates transition to an active alternative.

Electrical Compatibility: Both components share identical resistance value, temperature coefficient, and adjustment characteristics. The Bourns substitute's higher power rating (1W vs. 0.75W) and tighter tolerance (±5% vs. ±10%) provide improved performance margins without introducing incompatibility.

Mechanical Compatibility: Both components feature identical termination style (PC Pins), mounting type (Through Hole), and adjustment interface (Top Adjustment). The reduced physical diameter of the Bourns component (0.450" vs. 0.531") requires verification of PCB layout clearance but does not affect electrical or functional performance.

Certification Status: Both components carry identical MSL ratings and RoHS compliance certifications, supporting direct substitution in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3345P-1-201 be used as a direct replacement for the Nidec 1113T201?

A: Yes. Both components share identical resistance value, temperature coefficient, number of turns, adjustment type, and termination style. The Bourns substitute's higher power rating and improved tolerance are compatible with applications designed for the Nidec component.

Q: What is the significance of the different power ratings (0.75W vs. 1W)?

A: The Bourns component is rated for higher power dissipation. In applications where the original 0.75W rating was adequate, the 1W-rated substitute will operate with greater thermal margin and is fully compatible.

Q: Does the smaller physical size of the Bourns component affect compatibility?

A: The Bourns 3345P-1-201 has a smaller diameter (0.450" vs. 0.531"). PCB layout clearance must be verified to ensure the reduced size does not create mechanical interference with adjacent components or board features. Electrical and functional compatibility is unaffected.

Q: Are both components RoHS compliant?

A: Yes. Both the Nidec 1113T201 and Bourns 3345P-1-201 are ROHS3 compliant and carry identical MSL ratings of 1 (Unlimited).

Q: Why is the Nidec component listed as obsolete?

A: The Nidec 1113T201 is no longer in active production. The Bourns 3345P-1-201 is an active product with current manufacturing support, making it the recommended choice for new designs and ongoing production requirements.

Q: What tolerance difference exists between these components?

A: The Nidec component carries ±10% tolerance, while the Bourns substitute offers ±5% tolerance. The tighter tolerance of the substitute provides improved precision without introducing incompatibility.
