Equivalent & Substitute Parts for Bourns 4606X-102-124

Part Overview

The Bourns 4606X-102-124 is a 120k Ohm isolated 3-resistor network array in 6-SIP packaging, 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 The 4600X series has been superseded by active production alternatives that maintain electrical and mechanical compatibility while offering improved compliance status.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-102-124 is determined by the following criteria:

Primary Substitution Criteria (Must Match):

• Resistance value: 120k Ohm
• Tolerance: ±2%
• Number of resistors: 3
• Circuit type: Isolated
• Power per element: 300mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 6-SIP Through Hole
• Pin count: 6

Secondary Considerations:

• RoHS compliance status (compliance preferred for new designs)
• Product status (active vs. obsolete)
• Packaging format (Bulk vs. Tube)
• Physical dimensions (minor variations acceptable within tolerance)

All listed substitutes meet the primary electrical and mechanical criteria. Differences in product status, RoHS compliance, and packaging reflect manufacturing evolution rather than functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Select 4606X-102-124LF or 4306R-102-124LF. Both parts are active production items with ROHS3 compliance, meeting current regulatory requirements for new product development. The 4606X-102-124LF maintains the original 4600X series designation and is the direct active equivalent.

For Legacy System Maintenance: The 4606X-102-124 (original obsolete part) can be replaced with 4606X-102-124LF without design modification. Electrical and mechanical parameters are identical; the LF suffix indicates lead-free compliance.

For Cross-Series Substitution: The 4306R series (4306R-102-124 and 4306R-102-124LF) provides functional equivalence with minor physical dimension variations. These parts are suitable when 4600X series availability is constrained. The 4306R-102-124LF is preferred for new designs due to ROHS3 compliance.

Compliance Considerations: Parts with "LF" designation (4606X-102-124LF, 4306R-102-124LF) are lead-free and ROHS3 compliant. Non-LF variants remain available for legacy applications where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can I use 4606X-102-124LF as a direct replacement for 4606X-102-124? A: Yes. Both parts have identical electrical specifications (120k Ohm, ±2%, 300mW, ±100ppm/°C) and 6-SIP through-hole packaging. The LF suffix indicates lead-free manufacturing; no circuit design changes are required.

Q: What is the difference between the 4600X and 4300R series? A: Both series provide 120k Ohm isolated 3-resistor networks in 6-SIP packaging with identical electrical ratings. Physical dimensions differ slightly (4600X: 15.19mm × 2.49mm vs. 4300R: 14.83mm × 2.16mm), but both fit standard 6-SIP footprints. The 4300R series has a specified resistor-ratio-drift of 50ppm/°C, while the 4600X does not specify this parameter.

Q: Which part should I specify for a new design? A: Specify 4606X-102-124LF. It is an active production part with ROHS3 compliance and represents the current manufacturing standard for this function.

Q: Are there packaging differences between these parts? A: Yes. 4606X-102-124LF is supplied in Bulk packaging, while 4306R-102-124 and 4306R-102-124LF are supplied in Tube packaging. Bulk packaging is typical for high-volume procurement; Tube packaging is standard for lower-volume orders. Electrical and mechanical specifications remain unchanged.

Q: Can I substitute 4306R-102-124LF for 4606X-102-124LF? A: Yes, for applications where the minor physical dimension variation is acceptable. Both parts meet the electrical specifications and are ROHS3 compliant. Verify PCB footprint compatibility before design release.

Q: What does the "LF" suffix mean? A: LF indicates lead-free (RoHS3 compliant) manufacturing. These parts use lead-free solder and meet EU RoHS Directive requirements. Non-LF variants contain lead and are restricted in certain markets.
