Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM1501F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the RK73H1HTTC1501F while carrying Active product status. This option is preferred for new procurement when KOA supply chain continuity is required. ROHS3 compliance and AEC-Q200 automotive qualification are maintained.

AC0201FR-071K5L (YAGEO): This part provides cross-manufacturer substitution with equivalent electrical and mechanical parameters. YAGEO's AC series 0201 resistor meets all specified requirements including AEC-Q200 automotive qualification, ROHS3 compliance, and moisture resistance. This option is suitable when multi-source qualification is required or when YAGEO supply availability is preferred. Current inventory levels support immediate procurement.

Both substitute parts are functionally and mechanically interchangeable with the original RK73H1HTTC1501F in applications requiring 1.5 kOhms ±1% 0.05W thick film resistors in 0201 package with automotive-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1501F directly replace RK73H1HTTC1501F in existing designs?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc. and share identical electrical specifications (1.5 kOhms ±1%, 0.05W), physical dimensions (0201 package), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualifications (AEC-Q200). The primary difference is product status; RK73H1HTTCM1501F is Active while the original is Not For New Designs.

Q: Is AC0201FR-071K5L from YAGEO compatible with designs using RK73H1HTTC1501F?

A: Yes. The YAGEO AC0201FR-071K5L meets all critical electrical and mechanical parameters: 1.5 kOhms ±1% resistance, 0.05W power rating, 0201 package dimensions, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, and ROHS3 compliance. Cross-manufacturer substitution is valid when these parameters match.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: resistance value (1.5 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive rating (AEC-Q200), moisture resistance capability, RoHS compliance (ROHS3), and Moisture Sensitivity Level (1).

Q: Are there packaging differences between the substitute parts?

A: RK73H1HTTC1501F and AC0201FR-071K5L are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM1501F packaging type is not specified in available documentation. Confirm packaging requirements with supplier specifications before procurement.

Q: Do all three parts meet automotive standards?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are ROHS3 compliant. All feature moisture-resistant thick film construction with Moisture Sensitivity Level 1 (Unlimited), suitable for automotive applications across the specified operating temperature range of -55°C ~ 155°C.
