Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC2200F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 220 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package type: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts must maintain identical electrical and mechanical specifications across these parameters to ensure functional and regulatory compatibility in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2200F serves as the direct equivalent substitute for the RK73G1HTTC2200F. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73G series and maintain identical electrical, mechanical, and regulatory specifications.

The primary distinction between these parts is product status: the original RK73G1HTTC2200F is designated "Not For New Designs," while the RK73G1HTTCM2200F maintains "Active" status. This status difference reflects manufacturing lifecycle management and does not indicate any technical deficiency in the original part.

Both components satisfy AEC-Q200 automotive qualification requirements, ROHS3 compliance, and REACH regulatory requirements. The substitute part is suitable for direct replacement in existing designs and for new production applications requiring 220 Ohm ±1% thick film resistors in 0201 package format with automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2200F replace RK73G1HTTC2200F in automotive applications?

A: Yes. Both parts are electrically and mechanically identical, manufactured by the same supplier within the same series, and both carry AEC-Q200 automotive qualification. The substitute part is suitable for direct replacement.

Q: What does "Not For New Designs" mean for the RK73G1HTTC2200F?

A: This designation indicates the part has been transitioned out of the manufacturer's active product line. The RK73G1HTTCM2200F is the active equivalent and should be used for new production designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable in 0201 package footprints.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Is there any difference in electrical performance between these resistors?

A: No. Both parts have identical resistance (220 Ohms), tolerance (±1%), power rating (0.05W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C).
