Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC8203F are qualified based on the following electrical and mechanical parameters:

Substitution Criteria:

• Resistance value: 820 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 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)

Parts meeting all these criteria are classified as direct substitutes. Variations in product status (Active vs. Not For New Designs) do not affect electrical or mechanical compatibility but indicate design lifecycle positioning.

Engineering Selection Recommendations

RK73H1HTTCM8203F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and AEC-Q200 automotive qualification. The primary distinction is Active product status, indicating ongoing manufacturing support. This part is suitable for applications requiring continuity with the original RK73H1HTTC8203F design while ensuring long-term supply availability.

AC0201FR-07820KL (YAGEO)

This part is a cross-manufacturer substitute from YAGEO, meeting all electrical and mechanical requirements. It carries Active product status and includes moisture-resistant construction. Selection of this part introduces a secondary source from a different manufacturer, providing supply chain diversification while maintaining full electrical and mechanical compatibility with the original specification.

Both substitute parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity requirements. Selection between them depends on supply chain strategy, preferred supplier relationships, and inventory management objectives.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8203F be used as a direct replacement for RK73H1HTTC8203F?

A: Yes. Both parts share identical electrical specifications (820 kOhms ±1%, 0.05W), package geometry (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The difference in product status does not affect electrical or mechanical compatibility.

Q: What is the difference between RK73H1HTTC8203F and RK73H1HTTCM8203F?

A: Both parts are manufactured by KOA Speer Electronics, Inc., with identical electrical and mechanical specifications. The primary difference is product lifecycle status: RK73H1HTTC8203F is marked "Not For New Designs," while RK73H1HTTCM8203F carries "Active" status, indicating current manufacturing support and recommended use for ongoing production.

Q: Is AC0201FR-07820KL compatible with designs using RK73H1HTTC8203F?

A: Yes. AC0201FR-07820KL meets all specified electrical parameters (820 kOhms ±1%, 0.05W), package requirements (0201), temperature performance (±200ppm/°C, -55°C ~ 155°C), and automotive qualification (AEC-Q200). The manufacturer difference (YAGEO vs. KOA Speer Electronics, Inc.) does not affect compatibility when specifications are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RK73H1HTTCM8203F and AC0201FR-07820KL are both ROHS3 compliant, matching the original RK73H1HTTC8203F specification.

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

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. Storage and handling do not require special moisture control measures, and the part can be used immediately without baking or desiccant storage protocols.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and operate across the required temperature range (-55°C ~ 155°C), making them suitable for automotive circuit applications with equivalent reliability and performance characteristics.
