Equivalent & Substitute Parts for 4606X-102-123

Part Overview

The Bourns 4606X-102-123 is a 12k Ohm isolated 3-resistor network array in 6-SIP package configuration, rated for 300mW power per element with ±2% tolerance and ±100ppm/°C temperature coefficient. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The 4600X series has been superseded by active production alternatives that maintain electrical and mechanical compatibility while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-102-123 is determined by matching the following critical parameters: 12k Ohm resistance value, ±2% tolerance, 3-resistor isolated configuration, 300mW power rating per element, ±100ppm/°C temperature coefficient, 6-pin SIP package, and -55°C to 125°C operating temperature range. All substitute parts listed maintain these core electrical specifications and mechanical footprint compatibility.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Series): 4606X-102-123LF maintains identical specifications with improved RoHS3 compliance status and active product status.

Functional Equivalent (Alternative Series): 4306R-102-123 and 4306R-102-123LF provide the same electrical performance with minor dimensional variations and enhanced temperature stability through reduced resistor-ratio-drift specification (50ppm/°C vs. unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

For new designs and procurement of replacement components, 4606X-102-123LF is the primary recommended substitute. It maintains identical electrical specifications and mechanical compatibility while offering active product status and ROHS3 compliance, eliminating obsolescence risk and regulatory concerns associated with the original 4606X-102-123.

The 4306R series (4306R-102-123 and 4306R-102-123LF) provides functional equivalence with improved temperature stability through specified resistor-ratio-drift of 50ppm/°C. These parts are suitable for applications where enhanced temperature performance is beneficial. The 4306R-102-123LF variant is preferred for new designs due to ROHS3 compliance status.

Selection between 4606X-102-123LF and 4306R variants should account for dimensional constraints, as the 4306R series has slightly reduced footprint dimensions (14.83mm length vs. 15.19mm, 2.16mm width vs. 2.49mm, 4.95mm height vs. 5.08mm). REACH compliance requirements should be evaluated based on end-use application geography, as 4306R series parts are REACH Affected while 4606X series parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can 4606X-102-123LF be used as a direct replacement for 4606X-102-123?

A: Yes. The 4606X-102-123LF is a direct equivalent with identical electrical specifications (12k Ohm, ±2%, 300mW, ±100ppm/°C), mechanical footprint, and pin configuration. The primary differences are active product status and ROHS3 compliance.

Q: What are the dimensional differences between 4606X and 4306R series?

A: The 4306R series has a slightly smaller footprint: 14.83mm length (vs. 15.19mm), 2.16mm width (vs. 2.49mm), and 4.95mm seated height (vs. 5.08mm). Both maintain 6-SIP through-hole compatibility, but PCB layout spacing should be verified for the 4306R variants.

Q: Are there electrical performance differences between 4606X-102-123LF and 4306R-102-123LF?

A: Both parts meet the core specifications of 12k Ohm ±2%, 300mW per element, and ±100ppm/°C temperature coefficient. The 4306R series specifies resistor-ratio-drift at 50ppm/°C, providing enhanced temperature stability. This specification is not provided for the 4606X series.

Q: Which substitute should be selected for RoHS and REACH compliance?

A: For RoHS3 compliance, select either 4606X-102-123LF or 4306R-102-123LF. For REACH compliance, 4606X-102-123LF is REACH Unaffected, while 4306R variants are REACH Affected. Application geography and regulatory requirements should determine the appropriate selection.

Q: Can 4306R parts be used in existing PCB designs for 4606X-102-123?

A: Electrical substitution is valid. However, the reduced dimensions of the 4306R series (approximately 0.36mm shorter and 0.33mm narrower) may require PCB layout verification to ensure adequate clearance and proper component seating in through-hole positions.
