4606X-102-102 Equivalent & Substitute Parts

Part Overview

The Bourns 4606X-102-102 is a 1k Ohm isolated 3-resistor network array in 6-SIP package with ±2% tolerance and 300mW power per element. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from Bourns and Vishay Dale provide direct functional equivalence while offering improved compliance status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following core parameters: resistance value (1k Ohm), tolerance (±2%), circuit type (Isolated), power per element (300mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), number of resistors (3), pin count (6), and package type (6-SIP through hole).

Substitutes are grouped into two categories:

Direct Substitutes maintain identical specifications across all critical parameters and differ only in packaging format or compliance status. These include 4606X-102-102LF (Bourns, active, RoHS3 compliant), CSC06A031K00GPA (Vishay Dale, active), and CSC06A031K00GEK (Vishay Dale, active, RoHS3 compliant).

Similar Substitutes meet all core electrical and mechanical requirements but introduce minor variations in resistor-ratio-drift specification or physical dimensions. The 4306R series (4306R-102-102 and 4306R-102-102LF) specifies resistor-ratio-drift at 50ppm/°C versus the original part's unspecified drift, and feature slightly reduced physical dimensions (0.584" L x 0.085" W versus 0.598" L x 0.098" W).

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select 4606X-102-102LF (Bourns, active, bulk packaging) or CSC06A031K00GEK (Vishay Dale, active, bulk packaging). Both parts meet ROHS3 compliance and maintain identical electrical specifications to the original part.

For Bourns Product Line Continuity: The 4606X-102-102LF is the direct active equivalent within the Bourns 4600X series, offering identical specifications with improved compliance status and active product support.

For Alternative Manufacturer Sourcing: The Vishay Dale CSC series (CSC06A031K00GPA or CSC06A031K00GEK) provides functional equivalence with active status. CSC06A031K00GEK is preferred for RoHS3 compliance.

For Tighter Resistor Matching Requirements: The 4306R series (4306R-102-102 or 4306R-102-102LF) specifies resistor-ratio-drift at 50ppm/°C, providing defined temperature stability for matching-critical applications. The 4306R-102-102LF variant offers RoHS3 compliance. Note that physical dimensions are slightly reduced (14.83mm L x 2.16mm W versus 15.19mm L x 2.49mm W).

For Obsolescence Mitigation: All listed substitutes carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete 4606X-102-102.

Frequently Asked Questions (FAQ)

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

A: Yes. The 4606X-102-102LF is a direct substitute with identical electrical and mechanical specifications. The primary differences are active product status and RoHS3 compliance. The "LF" designation indicates lead-free construction.

Q: What is the difference between the 4606X and 4306R series?

A: Both series meet all core electrical requirements (1k Ohm, ±2%, 300mW, ±100ppm/°C). The 4306R series specifies resistor-ratio-drift at 50ppm/°C, whereas the 4606X does not specify this parameter. The 4306R has slightly smaller physical dimensions (14.83mm L x 2.16mm W versus 15.19mm L x 2.49mm W). Both mount identically in 6-SIP through-hole footprints.

Q: Are Vishay Dale CSC parts compatible with Bourns 4606X footprints?

A: Yes. All parts use identical 6-SIP through-hole package specifications with 6 pins. Physical dimensions are within acceptable tolerance for standard PCB footprints. CSC06A031K00GEK dimensions are 14.99mm L x 2.49mm W, which align with standard 6-SIP spacing.

Q: Which substitute should I select for new designs?

A: For new designs, select an active part with appropriate compliance status. 4606X-102-102LF (Bourns) or CSC06A031K00GEK (Vishay Dale) are recommended for RoHS3 compliance. If resistor matching stability is critical, specify the 4306R-102-102LF variant.

Q: What is the impact of the 50ppm/°C resistor-ratio-drift specification in the 4306R series?

A: Resistor-ratio-drift defines how the matching between individual resistors changes with temperature. The 4306R series specifies this at 50ppm/°C, providing defined performance for applications requiring stable resistor ratios across the operating temperature range. The original 4606X does not specify this parameter.

Q: Are there packaging format differences between substitutes?

A: Yes. 4606X-102-102 is supplied in tube packaging. 4606X-102-102LF is supplied in bulk. 4306R series parts are supplied in tube. Vishay Dale CSC parts are supplied in bulk. Packaging format does not affect electrical or mechanical compatibility.

Q: Can I mix different substitute parts in the same production run?

A: All listed substitutes are electrically and mechanically compatible. However, for consistency and traceability, maintain a single part number per production batch unless design documentation explicitly allows substitution.
