Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM7501F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and package format as the main part. The component carries Active product status, ensuring long-term availability and supply chain continuity. All compliance certifications (ROHS3, AEC-Q200, MSL 1) are maintained. The primary distinction is the absence of explicit moisture-resistant designation in the specification, though MSL 1 rating indicates unlimited moisture tolerance. This substitute is suitable for direct replacement in existing designs.

AC0201FR-077K5L (YAGEO)

This part is a cross-manufacturer substitute from YAGEO that meets all electrical and mechanical parameters. It maintains the 7.5 kOhms ±1% specification, 0.05W power rating, 0201 package format, and AEC-Q200 automotive qualification. The component includes explicit moisture-resistant construction and carries Active product status. All compliance requirements (ROHS3, MSL 1) are satisfied. This substitute provides an alternative sourcing option with higher current inventory availability (12531 Pcs).

Both substitutes are electrically and mechanically interchangeable with the RK73H1HTTC7501F within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7501F be used as a direct replacement for RK73H1HTTC7501F?

A: Yes. Both parts share identical resistance (7.5 kOhms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and automotive rating (AEC-Q200). Both are ROHS3 compliant with MSL 1 rating. The RK73H1HTTCM7501F is the manufacturer-recommended substitute and carries Active product status.

Q: What is the difference between RK73H1HTTC7501F and AC0201FR-077K5L?

A: Both parts are electrically and mechanically equivalent across all specified parameters: 7.5 kOhms ±1%, 0.05W, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 rating. The primary difference is manufacturer: KOA Speer Electronics, Inc. versus YAGEO. Both are ROHS3 compliant with MSL 1 rating and carry Active product status.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the -55°C ~ 155°C operating temperature range required for automotive environments.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means unlimited floor life. These components do not require special moisture control during storage, handling, or assembly processes.

Q: Can I mix these parts in the same production batch?

A: All three parts meet identical electrical specifications (7.5 kOhms ±1%, 0.05W, ±200ppm/°C) and package requirements (0201). They are functionally interchangeable within the specified parameters and can be used interchangeably in circuit designs.

Q: Why is RK73H1HTTC7501F marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. For new design work, the Active-status substitutes RK73H1HTTCM7501F or AC0201FR-077K5L are recommended to ensure long-term supply availability.
