Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC6200F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 620 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

All identified substitute parts meet these parameters without exception. Substitutes are grouped into two categories: manufacturer-recommended alternatives from KOA Speer Electronics, Inc., and direct cross-reference parts from alternative manufacturers that maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM6200F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended successor to the RK73H1HTTC6200F. It maintains identical electrical specifications and package format while carrying Active product status. Selection of this part is appropriate for applications requiring continuity with the original KOA Speer Electronics, Inc. supply chain and is the preferred choice for new procurement within existing designs.

AC0201FR-07620RL (YAGEO): This YAGEO part provides direct electrical and mechanical equivalence to the RK73H1HTTC6200F. It carries Active product status and meets all automotive AEC-Q200 requirements, RoHS3 compliance, and moisture resistance specifications. This part is suitable for applications where multi-source qualification is required or where YAGEO supply chain integration is preferred.

Both substitute parts are qualified for automotive applications and carry unlimited moisture sensitivity ratings, making them suitable for deployment in environments matching the original part's intended use.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6200F be used as a direct replacement for RK73H1HTTC6200F?

A: Yes. The RK73H1HTTCM6200F is electrically and mechanically identical to the RK73H1HTTC6200F across all specified parameters. The primary difference is product status: RK73H1HTTCM6200F is Active, while RK73H1HTTC6200F is Not For New Designs. Both parts are manufactured by KOA Speer Electronics, Inc. and are suitable for direct substitution.

Q: Is AC0201FR-07620RL compatible with designs specified for RK73H1HTTC6200F?

A: Yes. The AC0201FR-07620RL meets all electrical and mechanical requirements of the RK73H1HTTC6200F, including 620 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package format, AEC-Q200 automotive qualification, and moisture resistance. The manufacturer difference (YAGEO vs. KOA Speer Electronics, Inc.) does not affect functional compatibility.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC6200F?

A: This status indicates the part has been superseded by the manufacturer and is no longer recommended for new product designs. However, it remains available for existing applications and production support. For ongoing production of established designs, either the RK73H1HTTCM6200F or AC0201FR-07620RL should be specified to ensure long-term supply continuity.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. Both RK73H1HTTCM6200F and AC0201FR-07620RL carry AEC-Q200 automotive qualification, matching the original RK73H1HTTC6200F specification.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture handling precautions are required during storage or assembly.

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

A: Yes. All parts maintain the same operating temperature range of -55°C to 155°C and identical temperature coefficient of ±200ppm/°C, ensuring consistent performance across the specified thermal envelope.
