Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2000F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 200 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 ~ 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 and direct cross-reference parts from alternative manufacturers that satisfy identical electrical and mechanical specifications.

Engineering Selection Recommendations

RK73H1HTTCM2000F (KOA Speer Electronics, Inc.) - Manufacturer-Recommended Substitute

This part is the direct manufacturer-recommended equivalent from KOA Speer Electronics. It maintains identical electrical specifications, mechanical dimensions, and automotive qualifications as the RK73H1HTTC2000F. The primary distinction is active product status, indicating ongoing manufacturing support and availability. Selection of this part ensures continuity with the original design intent while securing long-term component availability. Current inventory: 701 units.

AC0201FR-07200RL (YAGEO) - Direct Cross-Reference Substitute

This YAGEO part provides full electrical and mechanical equivalence to the RK73H1HTTC2000F. All critical parameters—resistance, tolerance, power rating, package dimensions, temperature performance, and automotive AEC-Q200 qualification—are identical. YAGEO AC series thick film resistors are established alternatives in automotive applications. This part carries active product status and maintains ROHS3 compliance and MSL 1 rating. Current inventory: 1006 units.

Both substitute parts are suitable for direct replacement in applications where the RK73H1HTTC2000F was originally specified. Selection between them depends on supply chain preferences, inventory availability, and established vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2000F be used as a direct replacement for RK73H1HTTC2000F?

A: Yes. RK73H1HTTCM2000F is the manufacturer-recommended equivalent from KOA Speer Electronics. All electrical parameters (200 Ohms ±1%, 0.05W), mechanical dimensions (0201 package, 0.60mm x 0.30mm), temperature performance (±200ppm/°C, -55°C ~ 155°C), and automotive qualifications (AEC-Q200) are identical. The primary difference is product status: RK73H1HTTCM2000F is active, while RK73H1HTTC2000F is not for new designs.

Q: Is AC0201FR-07200RL compatible with designs using RK73H1HTTC2000F?

A: Yes. AC0201FR-07200RL from YAGEO meets all electrical and mechanical specifications of the RK73H1HTTC2000F. Resistance, tolerance, power rating, package format, temperature coefficient, operating temperature range, AEC-Q200 automotive rating, moisture resistance, RoHS compliance, and MSL rating are fully equivalent. This part is suitable for direct substitution.

Q: What is the significance of "Not For New Designs" status on RK73H1HTTC2000F?

A: "Not For New Designs" indicates that KOA Speer Electronics has superseded this part in their active product line. While existing inventory remains available, the manufacturer recommends using RK73H1HTTCM2000F for new applications. For legacy design support and ongoing production, both substitute parts provide equivalent functionality with active manufacturing status.

Q: Are all substitute parts available in the same packaging format?

A: RK73H1HTTC2000F and AC0201FR-07200RL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM2000F packaging information is not specified in available data but maintains identical 0201 package format. Confirm packaging requirements with your supplier for specific procurement needs.

Q: Do these parts meet automotive qualification requirements?

A: Yes. All three parts—RK73H1HTTC2000F, RK73H1HTTCM2000F, and AC0201FR-07200RL—carry AEC-Q200 automotive qualification. They are suitable for automotive applications requiring this certification standard.

Q: What is the moisture sensitivity level for these resistors?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. These components do not require special storage or handling procedures related to moisture sensitivity.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations.
