Substitute Part Grouping Explanation

Substitute parts for the CRCW080552K3FKEAC are qualified based on the following criteria:

• Identical resistance value: 52.3 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.125W (1/8W)
• Same package footprint: 0805 (2012 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance and MSL 1 rating

Parts meeting all these parameters are electrically and mechanically interchangeable in PCB designs without circuit modification.

Engineering Selection Recommendations

MCR10ERTF5232 (Rohm Semiconductor) is electrically and mechanically equivalent to the CRCW080552K3FKEAC but is discontinued at DiGi Electronics. This part should be used only if existing inventory is available and long-term supply is not required.

CR0805-FX-5232ELF (Bourns Inc.) is the recommended substitute. This part maintains all electrical specifications and package compatibility with the CRCW080552K3FKEAC. The CR0805-FX-5232ELF features moisture-resistant thick film construction and is currently in active production with substantial inventory availability. The maximum seated height of 0.026" (0.65mm) for the MCR10ERTF5232 is within acceptable tolerance for standard 0805 PCB designs, though the CR0805-FX-5232ELF and CRCW080552K3FKEAC both maintain 0.024" (0.60mm) maximum height.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF5232 be used as a direct replacement for CRCW080552K3FKEAC?

A: Yes, MCR10ERTF5232 meets all electrical and mechanical specifications for direct substitution. However, this part is discontinued at DiGi Electronics, limiting future availability.

Q: What is the primary advantage of CR0805-FX-5232ELF over the original CRCW080552K3FKEAC?

A: CR0805-FX-5232ELF includes moisture-resistant thick film construction while maintaining identical electrical performance and package footprint. Both parts are in active production.

Q: Are there height differences between these parts that affect PCB assembly?

A: The MCR10ERTF5232 has a maximum seated height of 0.026" (0.65mm), compared to 0.024" (0.60mm) for both CRCW080552K3FKEAC and CR0805-FX-5232ELF. This 0.002" difference is within standard PCB assembly tolerances for 0805 components.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes, CRCW080552K3FKEAC, MCR10ERTF5232, and CR0805-FX-5232ELF are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes, all three parts share identical operating temperature range of -55°C ~ 155°C and temperature coefficient of ±100ppm/°C, ensuring consistent performance across the full temperature spectrum.
