Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTC9530F be replaced with AC0201FR-07953RL?

A: Yes. Both parts are 953 Ohm ±1% thick film resistors in 0201 package with AEC-Q200 automotive qualification, identical power rating (0.05W), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and physical dimensions. Both include moisture-resistant construction and ROHS3 compliance.

Q: What is the difference between RK73H1HTTC9530F and RK73H1HTTCM9530F?

A: Both are KOA Speer Electronics parts within the RK73H series with identical electrical specifications (953 Ohms ±1%, 0.05W, ±200ppm/°C) and mechanical dimensions (0201 package). The primary difference is that moisture resistance is explicitly specified for RK73H1HTTC9530F but not documented for RK73H1HTTCM9530F in available technical data.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the -55°C to 155°C operating temperature range required for automotive environments.

Q: Does package format differ among these parts?

A: No. All three parts use 0201 (0603 Metric) package format with identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Are moisture sensitivity levels equivalent?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the design specifies 0201 package format and 953 Ohm ±1% tolerance. All parts are mechanically and electrically equivalent for direct substitution in surface mount applications.
