CSC08A03220RGEK Equivalent & Substitute Parts

Part Overview

The CSC08A03220RGEK is a 220 Ohm isolated 4-resistor network array manufactured by Vishay Dale in an 8-SIP through-hole package. This component is designed for applications requiring matched resistor networks with controlled temperature coefficients and tight tolerance specifications. The part is currently in active production status with 989 units in stock. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and procurement options when the primary part becomes unavailable or when specific packaging or compliance requirements necessitate component substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the CSC08A03220RGEK is determined by strict equivalence across the following critical parameters:

• Resistance value: 220 Ohm (exact match required)
• Tolerance: ±2% (exact match required)
• Number of resistors: 4 elements (exact match required)
• Circuit configuration: Isolated topology (exact match required)
• Power rating per element: 300mW (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package: 8-SIP through-hole (exact match required)

The identified substitute parts meet all these criteria and are therefore functionally and electrically equivalent for direct replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three components—CSC08A03220RGEK, 4308R-102-221LF, and 4608X-102-221LF—are active production parts with ROHS3 compliance and equivalent electrical specifications. Selection between these parts should be based on:

Packaging Format: The CSC08A03220RGEK and 4608X-102-221LF are supplied in bulk packaging, while the 4308R-102-221LF is supplied in tube packaging. Bulk packaging is suitable for high-volume manufacturing, whereas tube packaging provides organized component handling for lower-volume or manual assembly operations.

Compliance Requirements: The CSC08A03220RGEK is REACH Unaffected, while the 4308R-102-221LF is REACH Affected. The 4608X-102-221LF is REACH Unaffected. Applications subject to REACH regulations should verify compliance requirements with the selected substitute.

Inventory Availability: Current stock levels are 989 units (CSC08A03220RGEK), 2479 units (4308R-102-221LF), and 7045 units (4608X-102-221LF). Higher inventory levels may support extended lead times or volume requirements.

Physical Dimensions: Minor dimensional variations exist within the 8-SIP package specification. The CSC08A03220RGEK measures 0.790" L × 0.098" W with 0.195" seated height. The 4308R-102-221LF measures 0.784" L × 0.085" W with 0.195" seated height. The 4608X-102-221LF measures 0.798" L × 0.098" W with 0.200" seated height. These variations remain within standard 8-SIP package tolerances and do not affect PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 4308R-102-221LF and 4608X-102-221LF be used interchangeably with the CSC08A03220RGEK?

A: Yes. Both Bourns parts meet all electrical and mechanical specifications required for direct substitution. The 220 Ohm resistance, ±2% tolerance, 300mW power rating, ±100ppm/°C temperature coefficient, and 8-SIP package configuration are identical across all three parts.

Q: What is the difference between tube and bulk packaging?

A: Tube packaging organizes components in a continuous plastic strip for automated pick-and-place equipment or organized manual handling. Bulk packaging supplies loose components in a container, typically used for high-volume manufacturing environments with component counting and sorting systems.

Q: Are there any PCB layout considerations when substituting these parts?

A: The 8-SIP package footprint is standardized across all three parts. Minor dimensional variations (within 0.014" length and 0.013" width tolerances) do not affect PCB pad spacing or mounting hole alignment. Through-hole mounting remains consistent.

Q: What compliance certifications apply to each part?

A: All three parts are ROHS3 compliant. The CSC08A03220RGEK and 4608X-102-221LF are REACH Unaffected. The 4308R-102-221LF is REACH Affected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: Are there differences in temperature coefficient specifications?

A: The CSC08A03220RGEK specifies ±100ppm/°C. The 4308R-102-221LF specifies 50ppm/°C (without ±). The 4608X-102-221LF does not specify resistor-ratio-drift. All three parts meet the ±100ppm/°C operating temperature coefficient requirement across the -55°C to 125°C range.
