Engineering Selection Recommendations

RK73H1HTTCM3091F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It carries Active product status, indicating ongoing manufacturer support and availability. All electrical and mechanical parameters are identical to the RK73H1HTTC3091F. This option is preferred for applications requiring continuity within the same manufacturer's product line while transitioning away from the obsolescent RK73H1HTTC3091F designation.

AC0201FR-073K09L (YAGEO)

This part is a direct cross-reference substitute from YAGEO with Active product status. All electrical specifications, package dimensions, automotive certifications (AEC-Q200), and compliance ratings (ROHS3, MSL 1) are identical to the original part. This option provides an alternative source from a different manufacturer while maintaining full electrical and mechanical compatibility. Packaging is supplied in Tape & Reel (TR) format.

Both substitute parts satisfy all substitution criteria and are suitable for direct replacement in applications currently using the RK73H1HTTC3091F.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3091F be used as a direct replacement for RK73H1HTTC3091F?

A: Yes. Both parts share identical electrical parameters (3.09 kOhms ±1%, 0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and automotive certifications (AEC-Q200). The primary difference is product status: RK73H1HTTCM3091F is Active while RK73H1HTTC3091F is Not For New Designs.

Q: What is the difference between RK73H1HTTC3091F and RK73H1HTTCM3091F?

A: The part numbers differ only in the suffix designation (C versus CM). Both are manufactured by KOA Speer Electronics, Inc. and meet identical electrical and mechanical specifications. The CM variant represents the current active product line designation.

Q: Can AC0201FR-073K09L replace RK73H1HTTC3091F in automotive applications?

A: Yes. AC0201FR-073K09L is manufactured by YAGEO and carries AEC-Q200 automotive qualification identical to the original part. All electrical parameters, package dimensions, temperature range, and compliance certifications match the RK73H1HTTC3091F specification.

Q: Are there any differences in packaging between the substitute parts?

A: RK73H1HTTC3091F and AC0201FR-073K09L are both supplied in Tape & Reel (TR) format. RK73H1HTTCM3091F packaging format is not specified in available documentation. Confirm packaging requirements with your procurement department before finalizing part selection.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All three parts (RK73H1HTTC3091F, RK73H1HTTCM3091F, and AC0201FR-073K09L) are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is MSL 1 (Unlimited) for all parts.

Q: What is the temperature coefficient specification and why does it matter?

A: All parts have a temperature coefficient of ±200ppm/°C. This specification defines the maximum change in resistance value per degree Celsius across the operating temperature range. Matching this parameter ensures consistent circuit performance across the -55°C to 155°C operating range.
