Engineering Selection Recommendations

For New Designs: Select either RK73H1HTTCM1241F (KOA Speer Electronics) or AC0201FR-071K24L (YAGEO). Both components carry Active product status and meet all electrical, mechanical, and compliance requirements. RK73H1HTTCM1241F maintains manufacturer continuity with the original part series. AC0201FR-071K24L provides an alternative from an established automotive-qualified supplier.

For Existing Production (Legacy Support): The RK73H1HTTC1241F remains available with 1224 units in stock. Transition to an Active equivalent is recommended for long-term supply chain stability.

Compliance Considerations: All listed parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, suitable for automotive and industrial applications without additional handling restrictions.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1241F replace RK73H1HTTC1241F directly? A: Yes. Both parts are electrically and mechanically identical with 1.24 kOhms ±1% resistance, 0.05W power rating, 0201 package, and AEC-Q200 automotive qualification. RK73H1HTTCM1241F is the active production equivalent.

Q: What is the difference between RK73H1HTTC1241F and RK73H1HTTCM1241F? A: The primary difference is product status. RK73H1HTTC1241F is Not For New Designs, while RK73H1HTTCM1241F is Active. The main part includes moisture-resistant construction; the substitute does not explicitly specify this feature in the provided data.

Q: Is AC0201FR-071K24L compatible with automotive applications? A: Yes. AC0201FR-071K24L carries AEC-Q200 qualification, moisture-resistant construction, and operates across -55°C ~ 155°C, meeting automotive requirements.

Q: Are all substitutes available in Tape & Reel packaging? A: RK73H1HTTC1241F and AC0201FR-071K24L are confirmed Tape & Reel (TR) packaged. RK73H1HTTCM1241F packaging type is not specified in the provided data.

Q: Do these parts require special handling due to moisture sensitivity? A: No. All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these resistors in high-temperature applications? A: Yes. All parts operate across -55°C ~ 155°C with ±200ppm/°C temperature coefficient, suitable for automotive and industrial high-temperature environments.
