All substitute parts listed below meet these parameters without exception. Substitutes are grouped by manufacturer and product status to facilitate procurement decisions based on availability and design phase requirements.

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Support and Maintenance: The RK73H1HTTC7152F remains available with 19,827 pieces in current inventory. This part maintains full compliance with AEC-Q200 automotive standards and ROHS3 requirements. Selection of this part is appropriate for repair, rework, and field replacement of existing assemblies where the original specification is maintained.

For Active Production and New Designs: The RK73H1HTTCM7152F is the manufacturer-recommended successor from KOA Speer Electronics, Inc. This part carries "Active" product status and is the preferred selection for new designs and ongoing production. It maintains identical electrical and thermal specifications while ensuring long-term supply continuity. Current inventory of 691 pieces supports production requirements.

For Multi-Source Supply Strategy: The AC0201FR-0771K5L from YAGEO provides a cross-manufacturer equivalent with full parameter equivalence. This part is rated "Active" and carries 1,117 pieces in inventory. Selection of this part enables supply chain diversification and reduces single-source dependency. Both moisture-resistant and AEC-Q200 automotive certifications are maintained.

All three parts are suitable for direct substitution based on electrical performance, thermal characteristics, and automotive compliance ratings. Selection should be based on procurement availability, supply chain strategy, and design phase requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7152F be used as a direct replacement for RK73H1HTTC7152F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc. and share identical electrical specifications: 71.5 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are AEC-Q200 rated and ROHS3 compliant. The primary difference is product status: RK73H1HTTCM7152F is Active, while RK73H1HTTC7152F is Not For New Designs. RK73H1HTTCM7152F is the recommended choice for new designs and ongoing production.

Q: Is AC0201FR-0771K5L from YAGEO electrically equivalent to the KOA parts?

A: Yes. AC0201FR-0771K5L meets all critical electrical and mechanical parameters: 71.5 kOhms ±1%, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 rating, and ROHS3 compliance. This part enables cross-manufacturer substitution while maintaining full specification compliance.

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

A: This designation indicates the RK73H1HTTC7152F has been superseded in the manufacturer's active product line. The part remains available and fully functional for existing designs, maintenance, and field replacement. However, new designs should specify the active successor RK73H1HTTCM7152F to ensure long-term supply availability and manufacturer support.

Q: Are all substitute parts available in Tape & Reel packaging?

A: RK73H1HTTC7152F and AC0201FR-0771K5L are both specified as Tape & Reel (TR) packaging. RK73H1HTTCM7152F packaging type is not specified in available documentation. Confirm packaging requirements with the supplier before procurement.

Q: Do all parts meet automotive AEC-Q200 requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification. All are suitable for automotive applications requiring this certification standard.

Q: What is the difference in moisture resistance between the parts?

A: RK73H1HTTC7152F and AC0201FR-0771K5L are both specified as moisture-resistant. RK73H1HTTCM7152F does not include moisture resistance in its specification. All three parts carry MSL 1 (Unlimited) moisture sensitivity level rating. For applications requiring explicit moisture-resistant construction, specify either RK73H1HTTC7152F or AC0201FR-0771K5L.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts share identical 0201 (0603 Metric) package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). Physical footprint and PCB layout compatibility are identical across all three parts.
