Bourns 4608X-102-473 47kΩ Resistor Array 8-SIP Equivalent & Substitute Parts

Part Overview

The Bourns 4608X-102-473 is a 4-resistor isolated network array with 47kΩ resistance per element, rated at 300mW power dissipation per element, and ±2% tolerance. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates across -55°C to 125°C with ±100ppm/°C temperature coefficient in an 8-SIP through-hole package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4608X-102-473 is determined by the following critical parameters: resistance value (47kΩ), tolerance (±2%), number of resistors (4), circuit configuration (isolated), power rating per element (300mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), pin count (8), and package type (8-SIP through-hole).

Substitute parts are grouped into two categories:

Direct Manufacturer Substitutes (Bourns 4600X Series): Parts that maintain identical electrical specifications and are manufactured by the original supplier. The 4608X-102-473LF represents the active production equivalent with RoHS3 compliance.

Cross-Manufacturer Substitutes (Bourns 4300R Series and Vishay Dale): Parts that meet all core electrical parameters but originate from alternative manufacturers or product lines. These include the 4308R-102-473, 4308R-102-473LF (Bourns 4300R series), CSC08A0347K0GPA, and MSP08A0347K0GEJ (Vishay Dale). Minor dimensional variations exist within acceptable mechanical tolerances for 8-SIP packages.

Parameter Comparison

Engineering Selection Recommendations

For New Designs with RoHS3 Compliance Requirements: Select 4608X-102-473LF (Bourns, active production, bulk packaging) or MSP08A0347K0GEJ (Vishay Dale, active production, tube packaging). Both parts maintain full electrical equivalence and meet current regulatory compliance standards.

For Legacy System Maintenance (Non-RoHS Environments): The 4308R-102-473 (Bourns, active production) provides functional equivalence with established supply availability. This part is suitable for applications where RoHS compliance is not mandated.

For Cost-Optimized Procurement: The 4308R-102-473 and CSC08A0347K0GPA offer active production status with established inventory levels, reducing lead time risk compared to the obsolete 4608X-102-473.

For Packaging Considerations: Bulk packaging (4608X-102-473LF, CSC08A0347K0GPA) is appropriate for high-volume manufacturing. Tube packaging (4308R-102-473LF, MSP08A0347K0GEJ) suits lower-volume or mixed-component assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 4608X-102-473 be directly replaced with 4608X-102-473LF? A: Yes. The 4608X-102-473LF is the direct active production equivalent manufactured by Bourns. It maintains identical electrical specifications (47kΩ, ±2%, 300mW per element, ±100ppm/°C) and 8-SIP package configuration. The primary difference is RoHS3 compliance status and active product status versus obsolete classification.

Q: What are the mechanical differences between Bourns 4600X and 4300R series? A: Both series use 8-SIP through-hole packages with compatible pinouts. The 4600X series (4608X) measures 0.798" L × 0.098" W with 0.200" seated height. The 4300R series (4308R) measures 0.784" L × 0.085" W with 0.195" seated height. These dimensional variations remain within standard 8-SIP package tolerances and do not affect electrical performance or PCB footprint compatibility.

Q: Are Vishay Dale parts (CSC08A0347K0GPA, MSP08A0347K0GEJ) electrically equivalent? A: Yes. Both Vishay Dale parts meet all core electrical specifications: 47kΩ resistance, ±2% tolerance, 300mW power per element, ±100ppm/°C temperature coefficient, and -55°C to 125°C operating range. They are functionally interchangeable with Bourns equivalents in isolated 4-resistor network applications.

Q: Which substitute part has the best supply availability? A: The 4608X-102-473LF (Bourns, 9412 pcs in stock) and 4308R-102-473 (Bourns, 2890 pcs in stock) demonstrate the highest inventory levels. For Vishay Dale alternatives, the CSC08A0347K0GPA (799 pcs) and MSP08A0347K0GEJ (812 pcs) provide active production support with established supply chains.

Q: Does the resistor-ratio-drift specification affect substitution? A: The main part specifies ±100ppm/°C temperature coefficient without resistor-ratio-drift data. Substitute parts from the 4300R series and Vishay Dale specify ±50ppm/°C resistor-ratio-drift, indicating tighter matching stability. This represents an improvement over the original specification and does not restrict substitution compatibility.

Q: What compliance considerations apply to RoHS non-compliant parts? A: Parts marked as RoHS non-compliant (4608X-102-473, 4308R-102-473, CSC08A0347K0GPA) are suitable only for applications and markets where RoHS compliance is not required. For EU market distribution or applications subject to RoHS3 regulations, select RoHS3-compliant alternatives: 4608X-102-473LF, 4308R-102-473LF, or MSP08A0347K0GEJ.
