Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC5230F is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 523 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Substitute parts must satisfy all critical parameters without deviation. Packaging format (Tape & Reel vs. bulk) does not affect electrical or mechanical compatibility. Moisture-resistant construction is a feature present in the main part; substitute parts meeting all other parameters are functionally equivalent regardless of specific moisture-resistant designation variations.

Engineering Selection Recommendations

RK73H1HTTCM5230F (KOA Speer Electronics, Inc. - MFR Recommended Substitute)

This part is the manufacturer-recommended successor to the RK73H1HTTC5230F. It maintains identical electrical specifications, package format, and automotive AEC-Q200 qualification. The primary distinction is active product status, indicating ongoing manufacturing support and availability. This part is the preferred selection for applications requiring KOA Speer sourcing continuity.

AC0201FR-07523RL (YAGEO - Direct Equivalent)

This YAGEO component provides full electrical and mechanical equivalence to the main part. All critical parameters—resistance, tolerance, power rating, package format, temperature coefficient, operating range, and AEC-Q200 automotive qualification—are identical. ROHS3 compliance and MSL 1 rating match the original specification. This part is suitable for applications where multi-source component qualification is acceptable and YAGEO supply chain availability is preferred.

Both substitute parts are active products with confirmed inventory availability and meet all functional requirements for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM5230F be used as a direct replacement for RK73H1HTTC5230F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc. and share identical electrical specifications (523 Ohms ±1%, 0.05W), package format (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status; RK73H1HTTCM5230F is an active product while RK73H1HTTC5230F is marked "Not For New Designs."

Q: What is the difference between RK73H1HTTC5230F and AC0201FR-07523RL?

A: The primary difference is manufacturer: KOA Speer Electronics, Inc. versus YAGEO. All electrical parameters, package specifications, temperature characteristics, and automotive qualifications are identical. Both are thick film 0201 chip resistors rated at 523 Ohms ±1%, 0.05W with AEC-Q200 certification and ROHS3 compliance.

Q: Are there packaging differences between these substitute parts?

A: RK73H1HTTC5230F and AC0201FR-07523RL are both supplied in Tape & Reel (TR) format. RK73H1HTTCM5230F packaging type is not specified in available data. Tape & Reel packaging is standard for automated assembly processes and does not affect electrical or mechanical compatibility.

Q: Do all three parts meet automotive AEC-Q200 requirements?

A: Yes. RK73H1HTTC5230F, RK73H1HTTCM5230F, and AC0201FR-07523RL all carry AEC-Q200 automotive qualification ratings. All three are suitable for automotive applications requiring this certification standard.

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

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture-related degradation concerns. All three parts carry this rating, meaning they do not require special moisture-controlled storage or handling procedures prior to assembly.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your design and supply chain qualification processes permit multi-source component usage. RK73H1HTTCM5230F is the manufacturer-recommended upgrade path. AC0201FR-07523RL is a qualified equivalent from an alternative manufacturer. Both meet all specified electrical, mechanical, and compliance requirements for direct substitution.
