Bourns 4610X-101-203 Equivalent & Substitute Parts

Part Overview

The Bourns 4610X-101-203 is a 9-resistor network array with 20kΩ resistance per element, rated at 200mW power dissipation per element, and ±2% tolerance. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 10-SIP through-hole package provides standard PCB integration for applications requiring bussed resistor networks with stable temperature performance across the -55°C to 125°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4610X-101-203 is determined by matching the following critical parameters: 20kΩ resistance value, ±2% tolerance, 9-resistor configuration, bussed circuit topology, 200mW power per element, ±100ppm/°C temperature coefficient, 10-pin through-hole package, and -55°C to 125°C operating temperature range.

The substitute parts are grouped into two categories:

Direct Manufacturer Substitutes (Bourns 4600X Series): Parts maintaining identical electrical specifications and package dimensions with variations in product status and RoHS compliance.

Cross-Manufacturer Substitutes (Bourns 4300R Series and Vishay Dale CSC Series): Parts meeting all critical electrical parameters with minor dimensional variations and different resistor-ratio-drift specifications that remain within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Active Production (Recommended Primary Choice): The 4610X-101-203LF is the direct successor to the obsolete 4610X-101-203. It maintains identical electrical specifications and package dimensions while offering ROHS3 compliance and active product status. This part is the preferred substitution path for new designs and ongoing procurement.

For RoHS3 Compliance Requirement with Alternative Manufacturer: The 4310R-101-203LF provides ROHS3 compliance with active product status. Minor dimensional variations exist (0.984" L x 0.085" W versus 0.998" L x 0.098" W), and resistor-ratio-drift is specified at 50ppm/°C. REACH status is affected. Verify PCB layout compatibility before selection.

For Non-Compliant Legacy Applications: The 4310R-101-203 maintains RoHS non-compliant status matching the original part. Active product status ensures availability. Dimensional and resistor-ratio-drift specifications differ from the original.

For Cross-Manufacturer Substitution: The Vishay Dale CSC10A0120K0GPA meets all critical electrical parameters with active product status and RoHS non-compliant classification. Dimensional variations are minimal (0.990" L x 0.098" W). Resistor-ratio-drift is specified at ±50ppm/°C. REACH status is unaffected.

Frequently Asked Questions (FAQ)

Q: Can the 4610X-101-203LF be used as a direct replacement for the obsolete 4610X-101-203?

A: Yes. The 4610X-101-203LF is electrically and mechanically identical to the 4610X-101-203. The primary differences are active product status and ROHS3 compliance. No circuit redesign is required.

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

A: The "LF" designation indicates lead-free construction, which is associated with RoHS3 compliance. Parts without this suffix use traditional lead-based solder terminations.

Q: Are the 4310R series parts compatible with the original 4610X-101-203?

A: The 4310R-101-203 and 4310R-101-203LF are electrically compatible, meeting all critical specifications. Minor dimensional differences exist (0.984" L x 0.085" W versus 0.998" L x 0.098" W). Verify PCB footprint clearances before substitution.

Q: What is the difference between resistor-ratio-drift and temperature coefficient?

A: Temperature coefficient (±100ppm/°C) describes how individual resistor values change with temperature. Resistor-ratio-drift (50ppm/°C or ±50ppm/°C) describes how the matching between resistors changes with temperature. Both parameters are provided where specified.

Q: Can the Vishay Dale CSC10A0120K0GPA be used in place of the Bourns 4610X-101-203?

A: Yes. The CSC10A0120K0GPA meets all critical electrical specifications and operates within the same temperature range. Dimensional variations are minimal. Verify supplier availability and lead time before committing to cross-manufacturer substitution.

Q: What is REACH status and why does it matter?

A: REACH is a European Union regulation governing chemical substances. "REACH Affected" indicates the part contains substances of concern. "REACH Unaffected" indicates compliance. Selection depends on end-product regulatory requirements and target markets.

Q: Are there inventory considerations for these substitute parts?

A: Inventory levels vary by part and supplier. The 4610X-101-203LF has the highest reported inventory (4658 pcs), followed by 4310R-101-203LF (2491 pcs). Verify current availability with your component supplier before design commitment.
