Engineering Selection Recommendations

RK73H1HTTCM7151F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the main part while carrying Active product status. Selection of this part ensures continuity within the same manufacturer's product line and supports long-term component availability.

AC0201FR-077K15L (YAGEO): This part is a direct cross-reference from YAGEO and meets all electrical and mechanical parameter requirements. It carries Active product status and includes explicit moisture-resistant construction specification. This part provides an alternative source for the 7.15 kOhm 0201 package resistor with AEC-Q200 automotive qualification.

Both substitute parts are ROHS3 compliant, carry MSL 1 rating, and operate within the specified -55°C to 155°C temperature range. Selection between these options depends on supply chain requirements, inventory availability, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7151F be used as a direct replacement for RK73H1HTTC7151F?

A: Yes. RK73H1HTTCM7151F meets all electrical and mechanical parameter requirements for direct substitution. Both parts share identical resistance (7.15 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive rating. The primary difference is product status: RK73H1HTTCM7151F is Active while the main part is Not For New Designs.

Q: Is AC0201FR-077K15L compatible with applications designed for RK73H1HTTC7151F?

A: Yes. AC0201FR-077K15L meets all electrical and mechanical parameter requirements. Both parts share identical resistance, tolerance, power rating, package format, composition, temperature coefficient, operating range, and AEC-Q200 automotive rating. AC0201FR-077K15L is manufactured by YAGEO and carries Active product status.

Q: What are the key parameters that determine substitutability for this resistor?

A: Substitutability is determined by exact matching of: resistance value (7.15 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive rating (AEC-Q200), RoHS compliance (ROHS3), and moisture sensitivity level (MSL 1).

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both RK73H1HTTCM7151F and AC0201FR-077K15L carry AEC-Q200 automotive qualification, matching the main part specification. Both are ROHS3 compliant and rated for -55°C to 155°C operation.

Q: What is the difference between the main part and RK73H1HTTCM7151F?

A: The primary difference is product status. RK73H1HTTC7151F is marked "Not For New Designs" while RK73H1HTTCM7151F is Active. All electrical and mechanical parameters are identical. RK73H1HTTCM7151F represents the current production equivalent from the same manufacturer.

Q: Can these parts be used interchangeably in the same circuit board assembly?

A: Yes. All three parts (main part and both substitutes) share identical package format (0201), footprint dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and height specifications (0.010" max / 0.26mm max). They are mechanically and electrically interchangeable at the board level.
