Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by three critical parameters: resistance value (5.23 kOhms), package type (0402), and power rating (0.063W). All identified substitutes maintain these core specifications. Tolerance and temperature coefficient variations define substitution categories:

Direct Equivalent (Same Tolerance):

• RT0402FRE075K23L (YAGEO): Matches ±1% tolerance and ±50ppm/°C temperature coefficient

Upgrade Options (Improved Tolerance):

• CPF0402B5K23E1 (TE Connectivity): ±0.1% tolerance, ±25ppm/°C temperature coefficient
• RT0402BRD075K23L (YAGEO): ±0.1% tolerance, ±25ppm/°C temperature coefficient
• RT0402BRE075K23L (YAGEO): ±0.1% tolerance, ±50ppm/°C temperature coefficient

All substitutes are thin film composition, ROHS3 compliant, and rated for -55°C ~ 155°C operating range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): RT0402FRE075K23L is the direct equivalent, maintaining identical tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications. This part is suitable for one-to-one substitution with no circuit performance impact.

For Performance Enhancement: CPF0402B5K23E1 and RT0402BRD075K23L both offer improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), reducing circuit drift and improving accuracy in precision applications. These upgrades are compatible with the 0402 package footprint and maintain ROHS3 compliance.

For Temperature Stability with Improved Tolerance: RT0402BRE075K23L provides ±0.1% tolerance while maintaining the original ±50ppm/°C temperature coefficient, offering a middle-ground option for applications requiring tighter tolerance without temperature coefficient modification.

All substitute parts are ROHS3 compliant, MSL 1 rated, and REACH unaffected, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE075K23L replace MCS04020C5231FE000 without circuit redesign? A: Yes. RT0402FRE075K23L is a direct equivalent with identical resistance (5.23 kOhms), tolerance (±1%), power rating (0.063W), and temperature coefficient (±50ppm/°C). The 0402 package footprint is identical.

Q: What is the difference between the upgrade options? A: CPF0402B5K23E1 and RT0402BRD075K23L both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. RT0402BRE075K23L provides ±0.1% tolerance with the original ±50ppm/°C temperature coefficient. Selection depends on whether lower temperature drift is required.

Q: Are all substitutes compatible with the same PCB footprint? A: Yes. All substitutes use the 0402 (1005 Metric) package with identical land pattern dimensions (0.039" L x 0.020" W). Height variations (0.35mm vs 0.37mm maximum) are within standard PCB assembly tolerances.

Q: Do substitute parts meet the same compliance standards? A: Yes. All substitute parts are ROHS3 compliant, MSL 1 rated, and REACH unaffected, matching the original part's regulatory status.

Q: Which substitute offers the best inventory availability? A: RT0402BRD075K23L has the highest inventory at 23,869 pieces, followed by CPF0402B5K23E1 at 15,643 pieces.
