Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC10R2F is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to function as a direct substitute:

Electrical Parameters:

• Resistance value: 10.2 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated (max): 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Quality Parameters:

• Automotive rating: AEC-Q200
• Composition: Thick Film
• Moisture resistance: Required
• RoHS status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Identified substitute parts meet all these criteria and are therefore functionally and mechanically interchangeable with the original component.

Engineering Selection Recommendations

RK73H1HTTCM10R2F (KOA Speer Electronics, Inc.) - Manufacturer Recommended Substitute:

This part is the manufacturer-recommended alternative to the RK73H1HTTC10R2F. It maintains identical electrical specifications, package dimensions, and AEC-Q200 automotive compliance. The primary distinction is active product status, indicating ongoing manufacturing support and availability. This substitute is preferred for applications requiring continued supply chain reliability. Note that moisture resistance is not explicitly specified in the available data for this variant, though it shares the same series designation and core specifications.

AC0201FR-0710R2L (YAGEO) - Direct Equivalent Substitute:

This YAGEO component provides full electrical and mechanical equivalence to the original KOA part. It meets all critical parameters including 10.2 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, and moisture-resistant construction. The part maintains ROHS3 compliance and MSL 1 rating. Active product status ensures availability for production applications.

Both substitute parts are suitable for direct replacement in automotive applications where the original RK73H1HTTC10R2F is specified, provided that supply chain and procurement requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM10R2F be used as a direct replacement for RK73H1HTTC10R2F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical specifications (10.2 Ohms ±1%, 0.05W), package dimensions (0201), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), and AEC-Q200 automotive rating. The primary difference is product status; RK73H1HTTCM10R2F is active, while the original is not for new designs.

Q: Can YAGEO AC0201FR-0710R2L replace the KOA RK73H1HTTC10R2F?

A: Yes. The YAGEO AC0201FR-0710R2L meets all critical electrical and mechanical parameters: 10.2 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, and moisture-resistant construction. Cross-manufacturer substitution is valid when all specifications align.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires exact matching of: resistance value (10.2 Ohms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive rating (AEC-Q200), moisture resistance, RoHS compliance (ROHS3), and MSL rating (1).

Q: Does package type affect substitution?

A: Yes. The 0201 package (0603 metric) is a critical parameter. All substitute parts must use the identical 0201 package with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm) to ensure PCB compatibility and assembly process compatibility.

Q: Are there differences in moisture resistance between the substitute parts?

A: The RK73H1HTTC10R2F and AC0201FR-0710R2L are both specified as moisture resistant. The RK73H1HTTCM10R2F does not explicitly specify moisture resistance in the available data, though it shares the same series designation and core specifications as the original part. All three parts maintain MSL 1 (Unlimited) rating.

Q: What is the significance of AEC-Q200 rating for these parts?

A: AEC-Q200 is an automotive qualification standard that certifies the component for use in automotive applications. All three parts (original and substitutes) carry this rating, confirming suitability for automotive environments including temperature cycling, vibration, and reliability requirements specific to automotive electronics.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that procurement and supply chain requirements are satisfied. Both RK73H1HTTCM10R2F and AC0201FR-0710R2L are functionally and mechanically equivalent to RK73H1HTTC10R2F. Selection between them should consider manufacturer preference, supply availability, lead time, and cost factors.
