Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1623866-0 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 10 kOhms (exact match required)
• Power Rating: 0.75W / 3/4W (exact match required)
• Tolerance: ±10% (exact match required)
• Number of Turns: 15 (exact match required)
• Adjustment Type: Side Adjustment (exact match required)
• Resistive Material: Cermet (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pins (exact match required)

The Bourns 3006P-1-103LF satisfies all critical substitution criteria. Both components share identical electrical specifications, adjustment characteristics, and termination configuration. Dimensional variations remain within acceptable tolerance for standard PCB footprints. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Engineering Selection Recommendations

The Bourns 3006P-1-103LF (Trimpot® 3006 - Sealed series) is the direct functional equivalent for the obsolete TE Connectivity 1-1623866-0. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring availability for current and future procurement cycles. The original part's obsolete classification creates supply risk for ongoing applications.

Electrical Equivalence: All critical electrical parameters—resistance, power rating, tolerance, and temperature coefficient—are matched or exceeded. The substitute's superior temperature coefficient (±100ppm/°C versus ±250ppm/°C) provides enhanced stability across operating temperature ranges.

Compliance and Certifications: The substitute part carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic component procurement. The original part's compliance status is not specified.

Physical Compatibility: Dimensional differences (0.256" x 0.193" versus 0.250" x 0.190") are minimal and remain within standard PCB footprint tolerances for through-hole trimmer potentiometers. PC pin termination and side adjustment configuration are identical.

Packaging and Availability: The substitute is supplied in tube packaging with 26,040 units in current inventory, compared to the original part's obsolete status with limited remaining stock.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3006P-1-103LF be used as a direct replacement for the TE Connectivity 1-1623866-0 in existing designs?

A: Yes. Both components share identical electrical specifications (10 kOhms, 0.75W, ±10% tolerance, 15-turn side adjustment) and termination configuration (PC pins, through-hole mounting). Dimensional variations are within acceptable tolerance for standard PCB footprints.

Q: What is the significance of the temperature coefficient difference between the two parts?

A: The Bourns substitute exhibits a temperature coefficient of ±100ppm/°C compared to the original part's ±250ppm/°C. This indicates superior resistance stability across temperature variations, representing an improvement in performance characteristics.

Q: Are there compliance or regulatory differences between these components?

A: The Bourns 3006P-1-103LF carries ROHS3 compliance and REACH affected status. The original TE Connectivity part does not specify compliance certifications. For applications subject to regulatory requirements, the substitute's documented compliance status is advantageous.

Q: How do the physical dimensions affect PCB layout compatibility?

A: The original part measures 0.256" x 0.193" (6.50mm x 4.90mm), while the substitute measures 0.250" x 0.190" (6.35mm x 4.83mm). These differences are approximately 2% and remain within standard PCB footprint tolerances for rectangular through-hole trimmer potentiometers. No PCB redesign is required.

Q: What is the packaging format for the substitute part?

A: The Bourns 3006P-1-103LF is supplied in tube packaging, suitable for automated assembly processes and standard component handling procedures.

Q: Why is the original part classified as obsolete?

A: The TE Connectivity 1-1623866-0 is no longer in active production. The Bourns 3006P-1-103LF represents the current active equivalent, ensuring long-term supply chain continuity and access to current manufacturing standards.
