• Moisture sensitivity: MSL 1

All identified substitute parts meet these parameters without exception. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RK73H1HTTCM2201F (KOA Speer Electronics)

The RK73H1HTTCM2201F is the manufacturer-recommended direct upgrade from RK73H1HTTC2201F. Both components are manufactured by KOA Speer Electronics and share identical electrical and mechanical specifications. The RK73H1HTTCM2201F carries Active product status, ensuring long-term availability and continued manufacturing support. This part is the preferred choice for new designs and ongoing production requiring continuity with existing designs.

Secondary Recommendation: AC0201FR-072K2L (YAGEO)

The AC0201FR-072K2L provides an alternative from a different manufacturer while maintaining full parameter equivalence. YAGEO's AC series thick film resistor meets all electrical specifications, AEC-Q200 automotive qualification, and RoHS compliance requirements. This part is suitable for applications requiring multi-source qualification or where YAGEO components are already established in the supply chain. Active product status ensures sustained availability.

Selection Criteria:

• For design continuity within the KOA product family: Select RK73H1HTTCM2201F
• For supply chain diversification: Select AC0201FR-072K2L
• For existing inventory management: RK73H1HTTC2201F remains functionally equivalent until stock depletion

All three parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2201F directly replace RK73H1HTTC2201F in existing designs?

A: Yes. Both parts share identical electrical specifications (2.2 kOhms ±1%, 0.05W), mechanical dimensions (0201 package), temperature performance (±200ppm/°C, -55°C to 155°C), and automotive qualification (AEC-Q200). No circuit redesign or validation is required.

Q: What is the difference between RK73H1HTTC2201F and RK73H1HTTCM2201F?

A: The primary difference is product status. RK73H1HTTC2201F is marked "Not For New Designs," while RK73H1HTTCM2201F is Active. Both are manufactured by KOA Speer Electronics with identical performance characteristics. The "M" designation in RK73H1HTTCM2201F indicates the active production variant.

Q: Is AC0201FR-072K2L compatible with designs specified for RK73H1HTTC2201F?

A: Yes. AC0201FR-072K2L meets all mandatory electrical and mechanical parameters: 2.2 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 qualification, and ROHS3 compliance. Cross-manufacturer substitution is valid.

Q: Are there packaging differences between these parts?

A: RK73H1HTTC2201F and AC0201FR-072K2L are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM2201F packaging type is not specified in available data but maintains identical component specifications. Confirm packaging requirements with your supplier if TR format is mandatory.

Q: Do all three parts meet automotive standards?

A: Yes. All three parts carry AEC-Q200 automotive qualification, moisture-resistant thick film construction, MSL 1 rating, and ROHS3 compliance. They are suitable for automotive and industrial applications across the specified temperature range.

Q: Which part should be selected for new design work?

A: RK73H1HTTCM2201F is the recommended choice for new designs, as it carries Active product status and is the manufacturer-designated successor to the obsolete RK73H1HTTC2201F. AC0201FR-072K2L is an acceptable alternative if multi-source qualification is required.
