Substitute Part Grouping Explanation

Substitute parts for the RK73H2ATTDD2003F are qualified based on the following criteria:

• Resistance value: 200 kOhms
• Tolerance: ±1%
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Qualification: AEC-Q200
• RoHS Compliance: ROHS3 Compliant

The CRCW0805200KFKEA from Vishay Dale meets all electrical and mechanical compatibility requirements. The primary difference is the power rating (0.125W vs. 0.25W), which represents a derating consideration for applications requiring the full 0.25W dissipation capability of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the RK73H2ATTDD2003F and CRCW0805200KFKEA are active production components with AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on power dissipation requirements:

• Use RK73H2ATTDD2003F when circuit design requires the full 0.25W power rating capability.
• Use CRCW0805200KFKEA when circuit power dissipation does not exceed 0.125W, providing an alternative source from Vishay Dale.

Both components share identical electrical specifications (200 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C), package dimensions, and automotive qualification status. Physical height difference (0.60mm vs. 0.50mm) is within typical PCB assembly tolerances for 0805 packages.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805200KFKEA replace RK73H2ATTDD2003F in all applications?

A: Substitution is valid only when circuit power dissipation does not exceed 0.125W. Applications requiring the full 0.25W rating require the original RK73H2ATTDD2003F.

Q: Are the package dimensions identical?

A: Both components use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height differs by 0.004" (0.10mm), which is within standard PCB assembly specifications.

Q: Do both parts meet automotive standards?

A: Yes, both RK73H2ATTDD2003F and CRCW0805200KFKEA are qualified to AEC-Q200 automotive standards and are ROHS3 compliant.

Q: What is the temperature coefficient difference?

A: Both components have identical temperature coefficient specifications of ±100ppm/°C across the operating range of -55°C ~ 155°C.

Q: Are there inventory considerations?

A: RK73H2ATTDD2003F has 10,578 pieces in stock. CRCW0805200KFKEA has 5,100 pieces in stock. Availability should be verified with your supplier for production requirements.
