Bourns 4606X-102-151 Equivalent & Substitute Parts

Part Overview

The Bourns 4606X-102-151 is a 150 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 component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Active alternatives from the Bourns 4600X and 4300R series provide functional equivalence with improved product status and compliance options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-102-151 is determined by matching the following critical parameters: 150 Ohm resistance value, ±2% tolerance, 3-resistor isolated configuration, 300mW power rating per element, 6-pin SIP package, and -55°C to 125°C operating temperature range. All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Series): 4606X-102-151LF maintains identical specifications within the 4600X series, differing only in packaging format and compliance status.

Cross-Series Alternatives (4300R Series): 4306R-102-151 and 4306R-102-151LF provide electrical equivalence with minor dimensional variations and enhanced resistor-ratio-drift specification (50ppm/°C vs. unspecified for 4606X).

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select 4606X-102-151LF or 4306R-102-151LF. Both parts meet ROHS3 compliance standards, addressing regulatory requirements for new designs and procurement in restricted substance environments.

For Immediate Obsolescence Mitigation: 4606X-102-151LF is the primary substitute, maintaining identical electrical specifications and package dimensions while offering active product status and improved compliance posture.

For REACH-Compliant Applications: 4606X-102-151LF is preferred, as it maintains REACH Unaffected status. The 4300R series alternatives (4306R-102-151 and 4306R-102-151LF) carry REACH Affected designation and require additional compliance verification for specific applications.

For Dimensional Constraints: Verify PCB layout tolerance. The 4300R series (4306R-102-151, 4306R-102-151LF) exhibits slightly reduced footprint dimensions (14.83mm length, 2.16mm width, 4.95mm height) compared to the 4600X series (15.19mm length, 2.49mm width, 5.08mm height). Confirm mechanical clearance before substitution.

Frequently Asked Questions (FAQ)

Q: Can 4606X-102-151LF be used as a direct replacement for 4606X-102-151?

A: Yes. The 4606X-102-151LF maintains identical electrical specifications (150 Ohm, ±2%, 300mW, ±100ppm/°C) and package configuration (6-SIP). The primary differences are packaging format (Bulk vs. standard) and compliance status (ROHS3 Compliant vs. non-compliant). Electrical and mechanical compatibility is confirmed.

Q: What are the differences between the 4600X and 4300R series substitutes?

A: Both series provide 150 Ohm, ±2%, 3-resistor isolated networks in 6-SIP packages with identical electrical ratings. The 4300R series specifies resistor-ratio-drift at 50ppm/°C, whereas the 4600X series does not specify this parameter. The 4300R series exhibits slightly smaller physical dimensions and carries REACH Affected status, while the 4600X series maintains REACH Unaffected status.

Q: Are there any PCB layout considerations when substituting with 4300R series parts?

A: Yes. The 4300R series (4306R-102-151, 4306R-102-151LF) has reduced footprint dimensions compared to the 4600X series. Length is 0.36mm shorter (14.83mm vs. 15.19mm), width is 0.33mm narrower (2.16mm vs. 2.49mm), and seated height is 0.13mm lower (4.95mm vs. 5.08mm). Verify PCB pad spacing and component clearance before substitution.

Q: Which substitute part should be selected for new designs?

A: For new designs, 4606X-102-151LF is recommended. It provides active product status, ROHS3 compliance, identical electrical and mechanical specifications, and maintains REACH Unaffected status. This ensures long-term availability and regulatory alignment.

Q: Can 4306R-102-151 or 4306R-102-151LF be used in applications requiring REACH compliance?

A: The 4300R series carries REACH Affected designation. Applications with REACH compliance requirements should prioritize 4606X-102-151LF, which maintains REACH Unaffected status. Verify specific REACH substance restrictions applicable to your application before selecting 4300R alternatives.
