Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC8250F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 825 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitutes meet these parameters without exception. Substitution is valid across manufacturers when all electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM8250F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. It carries Active product status, indicating current production and long-term availability. All electrical and mechanical parameters match the main part specification. This option is preferred for new designs and ongoing production requiring KOA sourcing continuity. Note that moisture resistance is not explicitly specified for this variant, though the base RK73H series maintains this characteristic.

AC0201FR-07825RL (YAGEO): This part provides cross-manufacturer substitution with full parameter alignment, including explicit moisture-resistant thick film construction. YAGEO AC series components carry Active product status with established supply chain presence. This option is suitable for applications requiring multi-source qualification or when YAGEO supply chain advantages apply. All automotive and compliance certifications are maintained.

Both substitute parts are qualified for direct replacement in applications currently using RK73H1HTTC8250F, provided that design validation confirms compatibility with the specific application environment and manufacturing process requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8250F be used as a direct replacement for RK73H1HTTC8250F?

A: Yes. Both parts share identical electrical specifications (825 Ohms ±1%, 0.05W), package geometry (0201), temperature performance (±200ppm/°C, -55°C ~ 155°C), and automotive qualification (AEC-Q200). The primary difference is product status: RK73H1HTTCM8250F is Active, while the main part is Not For New Designs. Direct substitution is valid for existing designs and production.

Q: What is the difference between RK73H1HTTC8250F and AC0201FR-07825RL?

A: Both parts are electrically and mechanically identical in all specified parameters. The primary differences are manufacturer (KOA vs. YAGEO) and packaging designation. Both are AEC-Q200 qualified, ROHS3 compliant, and rated for -55°C ~ 155°C operation. AC0201FR-07825RL explicitly specifies moisture-resistant construction, while RK73H1HTTC8250F includes this feature in its detailed description.

Q: Are there any compatibility concerns when switching between KOA and YAGEO parts?

A: No compatibility concerns exist when all electrical and mechanical parameters match. Both manufacturers produce 0201 package resistors with identical footprint dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and height specifications (0.010" max / 0.26mm max). PCB assembly processes and reflow profiles remain unchanged.

Q: What does "Not For New Designs" status mean for RK73H1HTTC8250F?

A: This status indicates the part has been superseded and is no longer recommended for new product development. However, it remains available for existing production and design support. For new designs, RK73H1HTTCM8250F or AC0201FR-07825RL are the recommended alternatives.

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

A: RK73H1HTTC8250F and AC0201FR-07825RL are both specified as Tape & Reel (TR) packaging. RK73H1HTTCM8250F packaging type is not specified in available data. Confirm packaging requirements with the supplier before procurement.

Q: Do all parts meet automotive qualification requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification, making them suitable for automotive and high-reliability industrial applications requiring this certification.
