Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC6201F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 6.2 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)
• Height - Seated (Max): 0.010" (0.26mm) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 rating (required for automotive applications)
• RoHS3 compliance (required for regulatory adherence)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

Substitute parts must match all electrical, mechanical, and compliance parameters without exception. Variations in any parameter disqualify a part from substitution consideration.

Engineering Selection Recommendations

The RK73G1HTTCM6201F is the manufacturer-recommended substitute for the RK73G1HTTC6201F. Both parts are manufactured by KOA Speer Electronics, Inc., and maintain identical electrical, mechanical, and compliance specifications across all critical parameters.

Key Selection Factors:

Product Status Transition: The main part RK73G1HTTC6201F is designated "Not For New Designs," while the substitute RK73G1HTTCM6201F carries an "Active" product status. This indicates that KOA Speer Electronics has designated the substitute as the current production equivalent and recommended replacement for ongoing supply and new applications.

Compliance & Certification: Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 rating. No compliance gaps exist between the main part and substitute.

Electrical & Mechanical Equivalence: All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical parameters (package, dimensions, terminations) are identical. Direct substitution is electrically and mechanically sound.

Supply Chain Continuity: The substitute part maintains current production status with documented inventory availability, ensuring reliable supply for both replacement and new production requirements.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM6201F be used as a direct replacement for the RK73G1HTTC6201F in existing designs?

A: Yes. The RK73G1HTTCM6201F is electrically and mechanically equivalent to the RK73G1HTTC6201F. All critical parameters—resistance, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and automotive AEC-Q200 certification—are identical. Direct substitution is supported without circuit redesign or re-qualification.

Q: Why is the main part marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that KOA Speer Electronics has transitioned this part to end-of-life management. The manufacturer recommends using the RK73G1HTTCM6201F for all new applications. Existing designs currently using the main part may continue production with the substitute without modification.

Q: Are there any differences in packaging or handling between these two parts?

A: Both parts are supplied in the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). Both maintain Moisture Sensitivity Level 1 (Unlimited), requiring no special moisture control during storage or handling. Packaging format differences are not specified in the provided data.

Q: What is the significance of the ±50ppm/°C temperature coefficient?

A: The ±50ppm/°C temperature coefficient defines the resistor's stability across the operating temperature range of -55°C to 155°C. This specification ensures predictable resistance variation in automotive environments subject to thermal cycling. Both the main part and substitute maintain identical temperature coefficient performance.

Q: Is the RK73G1HTTCM6201F suitable for automotive applications?

A: Yes. The RK73G1HTTCM6201F carries full AEC-Q200 automotive qualification, identical to the main part. This certification confirms compliance with automotive reliability and performance standards, making it suitable for automotive-grade circuit applications.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates that the RK73G1HTTCM6201F meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. Both the main part and substitute maintain ROHS3 compliance, ensuring regulatory adherence in applicable markets.

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

A: Yes. Both parts are rated for operation across the identical temperature range of -55°C to 155°C with the same ±50ppm/°C temperature coefficient. They are interchangeable in high-temperature automotive and industrial applications within this specified range.
