Engineering Selection Recommendations

RK73H1HTTCM93R1F (KOA Speer Electronics, Inc.) - Manufacturer Recommended Upgrade

This part is the direct manufacturer upgrade path from RK73H1HTTC93R1F. Both components are from the same manufacturer and RK73H series family. RK73H1HTTCM93R1F carries Active product status, indicating ongoing production and long-term availability. All electrical and mechanical parameters are identical. This substitution is recommended for new designs and production transitions requiring KOA sourcing continuity.

AC0201FR-0793R1L (YAGEO) - Cross-Manufacturer Alternative

This YAGEO component provides a direct electrical and mechanical equivalent with Active product status. All critical parameters match the original specification, including resistance, tolerance, power rating, package dimensions, temperature coefficient, operating range, AEC-Q200 automotive qualification, moisture resistance, and RoHS compliance. This substitution is valid for applications where multi-source qualification is required or when YAGEO supply chain preference is established.

Both substitute parts maintain full compatibility with the original design specifications and automotive compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM93R1F be used as a direct replacement for RK73H1HTTC93R1F?

A: Yes. RK73H1HTTCM93R1F is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. All electrical specifications (93.1 Ohms ±1%, 0.05W), package dimensions (0201), thermal characteristics (±200ppm/°C, -55°C ~ 155°C), and compliance certifications (AEC-Q200, ROHS3, MSL 1) are identical. The primary difference is product status: RK73H1HTTCM93R1F is Active, while the original is Not For New Designs.

Q: Is AC0201FR-0793R1L from YAGEO compatible with designs using RK73H1HTTC93R1F?

A: Yes. AC0201FR-0793R1L meets all electrical and mechanical requirements. Resistance, tolerance, power rating, package, temperature coefficient, operating range, AEC-Q200 rating, moisture resistance, and RoHS compliance are fully matched. The component is from a different manufacturer but carries Active product status and is suitable for applications requiring cross-manufacturer qualification.

Q: What is the significance of "Not For New Designs" status on RK73H1HTTC93R1F?

A: This status indicates the part has been superseded by the manufacturer and is no longer recommended for new product development. Existing inventory remains available, but long-term supply cannot be guaranteed. Transitioning to RK73H1HTTCM93R1F or AC0201FR-0793R1L ensures design continuity and sustained component availability.

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

A: RK73H1HTTC93R1F and AC0201FR-0793R1L both specify moisture-resistant construction. RK73H1HTTCM93R1F does not explicitly state moisture resistance in the provided specifications, though both KOA parts share the same RK73H series designation and MSL 1 rating. For applications with critical moisture sensitivity requirements, AC0201FR-0793R1L or RK73H1HTTC93R1F are explicitly qualified.

Q: Do all substitute parts meet automotive AEC-Q200 qualification?

A: Yes. RK73H1HTTCM93R1F and AC0201FR-0793R1L both carry AEC-Q200 automotive qualification, matching the original RK73H1HTTC93R1F specification. All three parts are suitable for automotive applications requiring this certification level.

Q: What is the difference between 0201 and 0603 Metric package designations?

A: These are equivalent designations for the same physical package. 0201 is the imperial designation (0.024" L x 0.012" W), while 0603 Metric is the metric equivalent (0.60mm x 0.30mm). All substitute parts use this identical package with matching dimensions and termination count (2 terminations).
