• MSL rating: 1 (Unlimited)

All substitute parts listed below meet these exact specifications. Substitution is valid only when all parameters align with the original component requirements.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM13R3F (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 original RK73H1HTTC13R3F while carrying Active product status. This part is suitable for new production and ongoing applications. The primary distinction is that moisture resistance is not explicitly specified in the available data, though all other parameters remain equivalent.

AC0201FR-0713R3L (YAGEO): This part is a direct cross-reference alternative from YAGEO with Active product status. It meets all critical electrical parameters, maintains AEC-Q200 automotive qualification, includes moisture resistance capability, and carries full RoHS3 compliance. The AC0201FR-0713R3L is suitable for applications requiring a second-source component or where YAGEO supply chain availability is preferred.

Both substitute parts are qualified for automotive applications and carry unlimited moisture sensitivity levels, making them suitable for deployment in environments matching the original component's intended use.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM13R3F directly replace RK73H1HTTC13R3F in production?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share identical resistance (13.3 Ohms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), AEC-Q200 rating, and RoHS3 compliance. The RK73H1HTTCM13R3F carries Active product status, making it the preferred choice for ongoing production.

Q: Is AC0201FR-0713R3L compatible with applications designed for RK73H1HTTC13R3F?

A: Yes. The AC0201FR-0713R3L meets all specified electrical and mechanical parameters: 13.3 Ohms ±1%, 0.05W power rating, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive qualification, moisture resistance, and RoHS3 compliance. It is suitable for direct substitution in automotive and industrial applications.

Q: What is the significance of "Not For New Designs" status on the original part?

A: This designation indicates the RK73H1HTTC13R3F is in mature or end-of-life phase and should not be selected for new product designs. Substitute parts with Active status (RK73H1HTTCM13R3F and AC0201FR-0713R3L) are recommended for new designs while maintaining full compatibility with existing applications.

Q: Are there differences in moisture resistance between the substitute parts?

A: The RK73H1HTTC13R3F and AC0201FR-0713R3L both explicitly specify moisture resistance. The RK73H1HTTCM13R3F does not include moisture resistance in its specification data. For applications requiring confirmed moisture resistance capability, AC0201FR-0713R3L or the original RK73H1HTTC13R3F are preferred.

Q: Do all parts carry the same packaging format?

A: RK73H1HTTC13R3F and AC0201FR-0713R3L are supplied in Tape & Reel (TR) format. RK73H1HTTCM13R3F packaging type is not specified in available data. Confirm packaging requirements with the supplier before procurement.

Q: What compliance certifications apply to all substitute parts?

A: All three parts carry AEC-Q200 automotive qualification, RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity level. All are classified under ECCN EAR99 and HTSUS 8533.21.0030.
