Parameter Comparison

Engineering Selection Recommendations

For New Designs: Select RK73H1HTTCM84R5F (KOA Speer Electronics) or AC0201FR-0784R5L (YAGEO). Both parts carry Active product status and maintain full compliance with AEC-Q200 automotive qualification and ROHS3 requirements. RK73H1HTTCM84R5F is the manufacturer-recommended upgrade within the KOA product line. AC0201FR-0784R5L provides cross-manufacturer equivalence with identical electrical and environmental specifications.

For Existing Production / Maintenance: RK73H1HTTC84R5F remains available with 10,349 units in stock. Transition planning to active alternatives is recommended for long-term supply chain stability. RK73H1HTTCM84R5F offers the lowest transition risk as a direct KOA family upgrade with 1,134 units available.

Compliance Considerations: All listed parts satisfy ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings. Automotive applications requiring AEC-Q200 qualification are fully supported by all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM84R5F directly replace RK73H1HTTC84R5F in existing designs?

A: Yes. Both parts are KOA Speer Electronics products with identical electrical specifications (84.5 Ohms ±1%, 0.05W, 0201 package), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM84R5F is Active, while RK73H1HTTC84R5F is Not For New Designs.

Q: What is the difference between RK73H1HTTC84R5F and RK73H1HTTCM84R5F?

A: Both parts share identical electrical and mechanical parameters. RK73H1HTTCM84R5F does not list moisture resistance in its detailed description, while RK73H1HTTC84R5F explicitly specifies moisture-resistant construction. For applications requiring moisture resistance, verify RK73H1HTTCM84R5F specifications with KOA Speer Electronics before substitution.

Q: Is AC0201FR-0784R5L (YAGEO) a suitable cross-manufacturer substitute?

A: Yes. AC0201FR-0784R5L matches all critical parameters: 84.5 Ohms ±1%, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 qualification, moisture resistance, ROHS3 compliance, and MSL 1 rating. It is an Active product with 961 units in stock.

Q: Are there packaging differences between these substitutes?

A: RK73H1HTTC84R5F and AC0201FR-0784R5L are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM84R5F packaging is not specified in available data. Confirm packaging requirements with the supplier before procurement.

Q: Do all substitutes meet automotive AEC-Q200 requirements?

A: Yes. RK73H1HTTC84R5F, RK73H1HTTCM84R5F, and AC0201FR-0784R5L all carry AEC-Q200 qualification and are suitable for automotive applications within the specified operating temperature range of -55°C ~ 155°C.

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

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations and does not require special moisture control during storage, handling, or assembly. All three substitute parts carry this rating, eliminating moisture-related supply chain constraints.
