Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-101-203 is determined by the following critical parameters: resistance value (20kΩ), tolerance (±2%), number of resistors (5), power rating per element (200mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), circuit topology (bussed), pin count (6), and package type (6-SIP through-hole).

Substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): Parts maintaining identical electrical specifications and package dimensions with updated compliance status or packaging format.

Functional Equivalent (Alternative Manufacturer): Parts from different manufacturers meeting all critical electrical and mechanical parameters within specified tolerances, enabling direct circuit board replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 4606X-101-203LF

The 4606X-101-203LF is the direct equivalent of the obsolete 4606X-101-203, manufactured by Bourns Inc. under the same 4600X series. This part maintains identical electrical specifications and package dimensions while offering active product status and ROHS3 compliance. The LF suffix indicates lead-free construction, aligning with modern manufacturing standards. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: 4306R-101-203LF

The 4306R-101-203LF, also from Bourns Inc., provides an alternative within the 4300R series. This part meets all critical electrical parameters and maintains the same 6-SIP through-hole package. The 4306R-101-203LF offers active product status and ROHS3 compliance. Minor dimensional variations exist (0.584" L x 0.085" W versus 0.598" L x 0.098" W), which remain within acceptable PCB layout tolerances for through-hole mounting. This part is suitable for applications where the 4606X-101-203LF is unavailable.

Tertiary Recommendation: CSC06A0120K0GPA

The CSC06A0120K0GPA from Vishay Dale represents a cross-manufacturer functional equivalent. This part satisfies all critical electrical specifications and operates within the same temperature range. The CSC series maintains the 6-SIP through-hole package with compatible pin configuration. Dimensional variations are minimal (0.590" L x 0.098" W). This part is suitable for applications requiring multi-source qualification or when Bourns parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 4606X-101-203LF be used as a direct replacement for the 4606X-101-203?

A: Yes. The 4606X-101-203LF is electrically and mechanically identical to the 4606X-101-203, with the primary difference being active product status and ROHS3 compliance. No circuit modifications are required.

Q: What are the dimensional differences between the 4606X-101-203 and 4306R-101-203?

A: The 4606X-101-203 measures 0.598" L x 0.098" W (15.19mm x 2.49mm) with a maximum seated height of 0.200" (5.08mm). The 4306R-101-203 measures 0.584" L x 0.085" W (14.83mm x 2.16mm) with a maximum seated height of 0.195" (4.95mm). These differences are within standard PCB layout tolerances for through-hole components.

Q: Are there electrical performance differences between the Bourns 4606X and 4306R series?

A: Both series maintain identical resistance value (20kΩ), tolerance (±2%), power rating (200mW per element), and temperature coefficient (±100ppm/°C). The 4306R series specifies a resistor-ratio-drift of 50ppm/°C, whereas the 4606X series does not specify this parameter. This difference does not affect functional compatibility in standard applications.

Q: Can the Vishay Dale CSC06A0120K0GPA be used interchangeably with Bourns parts?

A: Yes. The CSC06A0120K0GPA meets all critical electrical specifications and maintains the same 6-SIP through-hole package. Dimensional variations are minimal and compatible with standard PCB layouts. This part is suitable for applications requiring cross-manufacturer sourcing.

Q: What is the significance of the "LF" suffix in part numbers?

A: The "LF" suffix indicates lead-free construction, compliant with ROHS3 standards. Parts with this designation use lead-free solder and are suitable for applications requiring RoHS compliance.

Q: Are there packaging format differences among these substitute parts?

A: The 4606X-101-203LF is supplied in bulk packaging, while the 4306R-101-203 and 4306R-101-203LF are supplied in tube packaging. Packaging format does not affect electrical or mechanical performance and is determined by procurement requirements.
