Nidec 1309P100 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Nidec Components Corporation 1309P100 is a 10 Ohm, 0.5W wirewound trimmer potentiometer with PC pin termination and side adjustment capability. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The 19-turn adjustment mechanism and through-hole mounting configuration define its primary application scope in legacy electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1309P100 is determined by the following critical parameters that must remain constant or compatible:

• Resistance Value: 10 Ohms (exact match required)
• Termination Style: PC Pins (through-hole connection method)
• Adjustment Type: Side Adjustment (mechanical interface requirement)
• Resistive Material: Wirewound (performance and stability characteristics)
• Mounting Type: Through Hole (PCB integration method)

The Bourns 3290P-1-100 qualifies as a substitute based on matching all critical parameters. Variations in power rating (0.5W to 1W), tolerance (±10% to ±5%), number of turns (19 to 25), and physical dimensions are permissible within the substitution framework, as these parameters do not prevent functional compatibility in the application circuit. The substitute part offers enhanced specifications in power handling and tolerance, with active product status and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 3290P-1-100 is the qualified substitute for the obsolete Nidec 1309P100. Selection is supported by the following factors:

• Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.
• The substitute part carries active product status with established supply chain availability, addressing the obsolescence of the original component.
• Bourns 3290P-1-100 includes REACH compliance, providing enhanced regulatory documentation for applications requiring extended traceability.
• Electrical parameters (resistance, temperature coefficient, termination method) are identical, ensuring circuit-level compatibility.
• The increased power rating (1W versus 0.5W) and improved tolerance (±5% versus ±10%) represent performance enhancements without introducing incompatibility.
• Physical dimension variation (rectangular versus square face) requires PCB layout verification to confirm mounting clearance and mechanical fit within the assembly.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3290P-1-100 be used as a direct replacement for the Nidec 1309P100?

A: The Bourns 3290P-1-100 is electrically and mechanically compatible as a substitute. Both components share identical resistance, termination style, adjustment type, and resistive material. Physical dimensions differ (rectangular versus square face), requiring confirmation that the PCB layout accommodates the substitute part's footprint.

Q: What is the significance of the power rating difference (0.5W to 1W)?

A: The substitute part's higher power rating (1W) provides additional thermal margin and is fully compatible with applications designed for the original 0.5W component. No circuit modification is required.

Q: Does the tolerance difference (±10% to ±5%) affect substitution?

A: The substitute part's tighter tolerance (±5%) represents an improvement over the original specification (±10%). This change enhances accuracy and does not introduce incompatibility.

Q: Why does the number of turns differ (19 to 25)?

A: The increased turn count (25 versus 19) provides finer adjustment resolution. This parameter does not prevent substitution but may affect adjustment sensitivity in the application circuit.

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

A: Both components are ROHS3 compliant with unlimited MSL rating. The substitute part includes REACH compliance, providing additional regulatory documentation. No compliance barriers exist for substitution.

Q: What should be verified before implementing the substitute part?

A: Confirm PCB layout compatibility with the rectangular face dimension (0.375" x 0.150") of the substitute part, as the original component features a square face (0.374" x 0.374"). Verify that mounting clearance and mechanical fit are acceptable for the assembly.
