Key Parameters

Substitute Part Grouping Explanation

The CRGCQ2010F680K from TE Connectivity Passive Product qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 680 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.75W
• Identical package designation: 2010 (5025 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical moisture resistance feature
• Identical RoHS3 compliance
• Identical MSL rating: 1 (Unlimited)

Physical dimensions remain within acceptable tolerances for the 2010 package standard, with both parts meeting the same electrical and environmental specifications required for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RK73H2HTTE6803F and CRGCQ2010F680K are active production parts with full AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical performance differences. The CRGCQ2010F680K from TE Connectivity offers higher inventory availability (5217 pieces) compared to the KOA part (1072 pieces). Both parts maintain ROHS3 compliance and identical electrical specifications across the full operating temperature range. The marginal difference in seated height (0.70mm versus 0.65mm) remains within standard 2010 package tolerances and does not affect circuit performance or PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRGCQ2010F680K replace RK73H2HTTE6803F in automotive applications?

A: Yes. Both parts carry identical AEC-Q200 ratings, resistance values, tolerances, power ratings, and operating temperature ranges. They are mechanically compatible within the 2010 package standard.

Q: Are there differences in physical dimensions between these parts?

A: Both parts share identical length and width dimensions (5.00mm x 2.50mm). The seated height differs by 0.05mm (0.70mm versus 0.65mm), which remains within standard 2010 package specifications and does not impact PCB assembly or circuit function.

Q: Do both parts meet moisture resistance requirements?

A: Yes. Both the RK73H2HTTE6803F and CRGCQ2010F680K feature moisture-resistant thick film construction with MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance ensures precise resistance values within a narrow range, critical for automotive circuits requiring stable performance across temperature variations and operating conditions. Both substitute parts maintain this specification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the KOA and TE Connectivity parts are ROHS3 compliant, meeting environmental and hazardous substance restrictions for automotive and industrial applications.

Q: What does the ±100ppm/°C temperature coefficient indicate?

A: This specification defines the resistance change rate per degree Celsius across the operating temperature range. Both parts maintain identical temperature stability characteristics, ensuring consistent circuit performance from -55°C to 155°C.
