Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC1002F is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Resistance value: 10 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Substitution Categories:

Category 1 - Manufacturer Recommended Equivalent (Packaging Variant): RK73H1HTTCM1002F differs only in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) while maintaining identical electrical and mechanical specifications. This part is Active status, making it the preferred upgrade path.

Category 2 - Direct Cross-Manufacturer Substitute: AC0201FR-0710KL (YAGEO) meets all electrical parameters and maintains AEC-Q200 automotive qualification. Packaging is Cut Tape & Digi-Reel®, matching the original part format.

Category 3 - Similar Substitute with Parameter Variance: RC0201FR-0710KL (YAGEO) matches all core electrical parameters but lacks explicit AEC-Q200 automotive rating and has a reduced operating temperature upper limit of 125°C versus 155°C for the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): RK73H1HTTCM1002F is the manufacturer-recommended equivalent. It maintains identical electrical specifications, AEC-Q200 automotive qualification, and full operating temperature range (-55°C ~ 155°C). The only difference is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®). This part carries Active product status, ensuring long-term availability and supply chain stability.

For Cross-Manufacturer Substitution: AC0201FR-0710KL (YAGEO) provides full electrical and mechanical equivalence with AEC-Q200 automotive qualification maintained. Operating temperature range and packaging format match the original part exactly. This option is suitable for applications requiring automotive-grade components.

For Non-Automotive or Temperature-Limited Applications: RC0201FR-0710KL (YAGEO) is electrically equivalent but lacks AEC-Q200 automotive rating and operates to 125°C maximum instead of 155°C. This part is suitable only for applications where automotive qualification is not required and maximum operating temperature does not exceed 125°C.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1002F be used as a direct replacement for RK73H1HTTC1002F?

A: Yes. RK73H1HTTCM1002F is the manufacturer-recommended equivalent with identical electrical and mechanical specifications. The difference is packaging format only (Tape & Reel vs. Cut Tape & Digi-Reel®). Both parts meet AEC-Q200 automotive qualification and operate across -55°C ~ 155°C.

Q: What is the difference between AC0201FR-0710KL and RC0201FR-0710KL?

A: Both are YAGEO 10 kOhms ±1% 0201 resistors with identical electrical parameters. AC0201FR-0710KL carries AEC-Q200 automotive qualification and operates to 155°C. RC0201FR-0710KL lacks AEC-Q200 rating and operates to 125°C maximum. Select AC0201FR-0710KL for automotive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RK73H1HTTCM1002F, AC0201FR-0710KL, and RC0201FR-0710KL are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) affects only handling, storage, and supply chain logistics. Electrical and mechanical specifications remain identical.

Q: Which substitute should be selected for new automotive designs?

A: RK73H1HTTCM1002F (Active status, KOA manufacturer) or AC0201FR-0710KL (Active status, YAGEO manufacturer). Both maintain AEC-Q200 qualification and full operating temperature range. The original part RK73H1HTTC1002F is marked Not For New Designs.

Q: Can RC0201FR-0710KL be used in automotive applications?

A: RC0201FR-0710KL lacks AEC-Q200 automotive qualification. It is not suitable for applications requiring automotive-grade components. Use AC0201FR-0710KL or RK73H1HTTCM1002F for automotive applications.

Q: What is the significance of MSL 1 (Unlimited)?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All substitute parts carry this rating, ensuring consistent handling and storage procedures.
