• Tolerance: ±2% (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Power 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)
• RoHS3 compliance: Required for regulatory compatibility

The identified substitute parts meet all electrical and mechanical parameters specified above, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CSC08A03100RGEK, 4308R-102-101LF, and 4608X-102-101LF—maintain Active product status and meet ROHS3 compliance requirements. Selection between these parts should be based on:

Availability and Lead Time: Inventory levels vary across manufacturers. The 4308R-102-101LF (Bourns) offers 2902 units in stock, while the 4608X-102-101LF (Bourns) provides 2470 units. The original CSC08A03100RGEK (Vishay Dale) maintains 999 units.

Packaging Format: The CSC08A03100RGEK and 4608X-102-101LF are supplied in Bulk packaging, while the 4308R-102-101LF is supplied in Tube packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Regulatory Compliance: The CSC08A03100RGEK and 4608X-102-101LF maintain REACH Unaffected status. The 4308R-102-101LF is REACH Affected, which may impact supply chain considerations in certain regions.

Physical Dimensions: Minor dimensional variations exist within acceptable tolerances. The 4308R-102-101LF measures 0.784" L x 0.085" W with 0.195" seated height. The 4608X-102-101LF measures 0.798" L x 0.098" W with 0.200" seated height. The CSC08A03100RGEK measures 0.790" L x 0.098" W with 0.195" seated height. These variations are within standard PCB layout tolerances for through-hole components.

Frequently Asked Questions (FAQ)

Q: Can the 4308R-102-101LF and 4608X-102-101LF be used interchangeably with the CSC08A03100RGEK?

A: Yes. Both Bourns parts meet all critical electrical parameters: 100 Ohm resistance, ±2% tolerance, 4-resistor isolated configuration, 300mW power per element, ±100ppm/°C temperature coefficient, and -55°C to 125°C operating range. All three parts use identical 8-SIP through-hole packaging and maintain ROHS3 compliance.

Q: What are the key differences between the substitute parts?

A: The primary differences are manufacturer (Vishay Dale vs. Bourns), packaging format (Bulk vs. Tube), REACH classification status, and minor physical dimensions. Electrical performance and functional characteristics are equivalent.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: The dimensional variations between parts are minimal and fall within standard through-hole component tolerances. PCB designs accommodating the CSC08A03100RGEK will accept both substitute parts without layout modifications.

Q: Does REACH classification affect part selection?

A: REACH classification may impact supply chain logistics depending on regional regulations and customer requirements. The CSC08A03100RGEK and 4608X-102-101LF are REACH Unaffected, while the 4308R-102-101LF is REACH Affected. Verify compliance requirements with your supply chain or regulatory team.

Q: What is the significance of the Resistor-Ratio-Drift specification?

A: The CSC08A03100RGEK specifies ±50ppm/°C ratio drift, while the 4608X-102-101LF does not provide this specification. The 4308R-102-101LF specifies 50ppm/°C. For applications requiring tight resistor matching over temperature, the CSC08A03100RGEK and 4308R-102-101LF are preferred.
