Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73H2HTTE2201F is determined by strict equivalence across the following parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture resistance capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The CRGCQ2010F2K2 manufactured by TE Connectivity Passive Product meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RK73H2HTTE2201F and CRGCQ2010F2K2 are active production parts with identical electrical specifications and automotive compliance. Selection between these parts may be based on:

• Availability: CRGCQ2010F2K2 has significantly higher inventory (214,303 pieces) compared to RK73H2HTTE2201F (760 pieces)
• Seated height: CRGCQ2010F2K2 has a maximum seated height of 0.026" (0.65mm) versus 0.028" (0.70mm) for the KOA part, which may be relevant for space-constrained applications
• Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification
• Both parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions

Frequently Asked Questions (FAQ)

Q: Can CRGCQ2010F2K2 be used as a direct replacement for RK73H2HTTE2201F?

A: Yes. Both parts share identical resistance value (2.2 kOhms), tolerance (±1%), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The electrical and mechanical compatibility is complete.

Q: Are there any dimensional differences between these parts?

A: The length and width are identical at 0.197" L x 0.098" W (5.00mm x 2.50mm). The seated height differs slightly: RK73H2HTTE2201F has a maximum of 0.028" (0.70mm) while CRGCQ2010F2K2 is 0.026" (0.65mm). This minor difference is typically not significant for standard PCB assembly.

Q: Do both parts meet automotive standards?

A: Yes. Both the RK73H2HTTE2201F and CRGCQ2010F2K2 carry AEC-Q200 qualification and are suitable for automotive applications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), meaning they have unlimited shelf life under standard storage conditions and do not require special moisture control during handling or storage.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant.

Q: What is the difference in availability between these two parts?

A: The CRGCQ2010F2K2 has substantially higher inventory availability (214,303 pieces) compared to the RK73H2HTTE2201F (760 pieces), which may influence procurement decisions for high-volume applications.
