Key Parameters

Substitute Part Grouping Explanation

Substitution for the 4606X-102-103 is determined by matching the following critical parameters: resistance value (10kΩ), tolerance (±2%), number of resistors (3), circuit configuration (isolated), power rating per element (300mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), package type (6-SIP), and through-hole mounting compatibility.

Substitute parts are grouped into two categories:

Direct Substitutes (Same Series): Parts maintaining identical electrical specifications and the same base product line (4600X series). The 4606X-102-103LF is a direct substitute with active product status and improved RoHS3 compliance.

Compatible Alternatives (Different Series): Parts from alternative manufacturers or product lines (4300R series and Vishay Dale CSC series) that maintain all critical electrical parameters but may differ in physical dimensions, resistor-ratio-drift specifications, or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The 4606X-102-103LF is the primary recommended substitute. It maintains identical electrical specifications to the original 4606X-102-103 while offering active product status and ROHS3 compliance, eliminating obsolescence risk and meeting modern regulatory requirements.

For RoHS3 Compliance Requirements: Both 4606X-102-103LF and 4306R-102-103LF satisfy ROHS3 compliance. The 4606X-102-103LF preserves the original 4600X series lineage, while 4306R-102-103LF provides an alternative from the 4300R series with identical electrical performance.

For Applications with Tighter Resistor Matching Requirements: The 4306R-102-103 and 4306R-102-103LF specify resistor-ratio-drift of 50ppm/°C, providing enhanced stability compared to the original part. The CSC06A0310K0GPA from Vishay Dale offers equivalent drift specification at ±50ppm/°C.

For Space-Constrained PCB Layouts: The 4306R series (4306R-102-103 and 4306R-102-103LF) and CSC06A0310K0GPA offer reduced physical dimensions compared to the 4606X series, with maximum seated heights of 4.95mm versus 5.08mm.

For REACH Compliance: The 4606X-102-103LF is REACH Unaffected. The 4306R series and CSC06A0310K0GPA are REACH Affected; verify compliance requirements for your specific application jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can the 4606X-102-103LF be used as a direct replacement for the 4606X-102-103?

A: Yes. The 4606X-102-103LF maintains identical electrical specifications, package type, and pin configuration. The primary differences are active product status and ROHS3 compliance. PCB layout and schematic integration remain unchanged.

Q: What is the difference between the 4600X and 4300R series?

A: Both series provide 3-resistor isolated networks with identical resistance values, tolerance, power ratings, and temperature coefficients. The 4300R series specifies resistor-ratio-drift at 50ppm/°C, while the 4600X series does not specify this parameter. Physical dimensions differ slightly, with 4300R components being more compact.

Q: Are the Vishay Dale CSC06A0310K0GPA and Bourns parts electrically interchangeable?

A: Yes, for the specified electrical parameters. All parts maintain 10kΩ resistance, ±2% tolerance, 300mW power per element, ±100ppm/°C temperature coefficient, and -55°C to 125°C operating range. Physical dimensions and manufacturer-specific certifications differ.

Q: Which substitute should I select if PCB space is limited?

A: The 4306R-102-103LF or CSC06A0310K0GPA offer the smallest footprint with maximum seated heights of 4.95mm compared to 5.08mm for the 4606X series. Verify PCB layout compatibility before selection.

Q: Does the resistor-ratio-drift specification affect my application?

A: Resistor-ratio-drift determines how the ratio between resistors changes with temperature. If your circuit requires stable resistor ratios across the operating temperature range, the 4306R series (50ppm/°C drift) or CSC06A0310K0GPA (±50ppm/°C drift) provide tighter specifications than the original 4606X-102-103.

Q: What is the impact of RoHS compliance on part selection?

A: ROHS3-compliant parts (4606X-102-103LF and 4306R-102-103LF) meet current environmental regulations and are required for many applications in regulated markets. RoHS non-compliant parts may face supply restrictions or regulatory barriers depending on end-use jurisdiction.
