Bourns 4606X-102-183 18kΩ Resistor Array Equivalent & Substitute Parts

Part Overview

The Bourns 4606X-102-183 is a 3-resistor isolated network array with 18kΩ resistance per element, rated at 300mW power dissipation per element, and ±2% tolerance. This component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts from the active product portfolio is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-102-183 is determined by the following critical parameters: resistance value (18kΩ), tolerance (±2%), number of resistors (3), circuit configuration (isolated), power rating per element (300mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), pin count (6), and package type (6-SIP through-hole).

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in product status (active vs. obsolete), RoHS compliance, packaging format (bulk vs. tube), and dimensional tolerances are secondary considerations that do not affect functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

For new designs and procurement, the 4606X-102-183LF is the primary recommended substitute. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. The bulk packaging format accommodates high-volume manufacturing requirements.

The 4306R series (4306R-102-183 and 4306R-102-183LF) provides functional equivalence with all critical electrical parameters matched. The 4306R-102-183LF variant is suitable for applications requiring ROHS3 compliance. Both 4306R variants are supplied in tube packaging, appropriate for lower-volume or manual assembly operations.

Selection between 4606X-102-183LF and 4306R-102-183LF should be based on packaging requirements (bulk vs. tube) and supply chain availability. Both parts satisfy the core electrical and mechanical requirements of the obsolete 4606X-102-183.

Frequently Asked Questions (FAQ)

Q: Can the 4606X-102-183LF directly replace the 4606X-102-183 in existing designs?

A: Yes. The 4606X-102-183LF maintains identical electrical specifications (18kΩ, ±2% tolerance, 300mW per element, ±100ppm/°C temperature coefficient) and package configuration (6-SIP through-hole). The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

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

A: Both series meet the specified electrical parameters for this application. The 4306R series specifies a resistor-ratio-drift of 50ppm/°C, whereas the 4606X series does not provide this specification. Physical dimensions differ slightly: 4306R measures 0.584" L × 0.085" W (14.83mm × 2.16mm) with 0.195" maximum seated height, compared to 4606X at 0.598" L × 0.098" W (15.19mm × 2.49mm) with 0.200" maximum seated height. Both use identical 6-SIP through-hole packages.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The 4606X-102-183LF is supplied in bulk packaging, suitable for automated assembly and high-volume production. The 4306R-102-183 and 4306R-102-183LF are supplied in tube packaging, appropriate for manual assembly or lower-volume applications. Packaging selection should align with manufacturing process requirements.

Q: Which substitute part offers the best compliance profile?

A: Both 4606X-102-183LF and 4306R-102-183LF are ROHS3 compliant. The 4306R-102-183LF is REACH affected, while the 4606X-102-183LF is REACH unaffected. Compliance requirements specific to your application should guide final selection.

Q: Is the 4606X-102-183 still available for procurement?

A: The 4606X-102-183 is classified as obsolete. Current inventory exists but is limited. For new procurement and long-term supply assurance, transition to an active substitute part is recommended.
