Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC8253F is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Resistance value: 825 kOhms (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)
• Moisture resistance: Required
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Substitute parts must satisfy all criteria listed above to ensure functional and regulatory equivalence in automotive and industrial applications.

Engineering Selection Recommendations

RK73H1HTTCM8253F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains all electrical and mechanical specifications identical to the main part and carries Active product status. However, this variant does not include moisture-resistant properties, which were specified in the original RK73H1HTTC8253F. Selection of this part is appropriate only when moisture resistance is not a design requirement.

AC0201FR-07825KL (YAGEO): This part is a direct cross-reference substitute manufactured by YAGEO. It matches all critical parameters including resistance, tolerance, power rating, package, composition, temperature coefficient, operating temperature range, AEC-Q200 automotive qualification, moisture resistance, RoHS compliance, and MSL rating. The AC0201FR-07825KL carries Active product status and is suitable for direct replacement in applications requiring full parameter equivalence.

For applications where the original RK73H1HTTC8253F is no longer available, the AC0201FR-07825KL provides complete functional and regulatory equivalence. The RK73H1HTTCM8253F may be considered only if moisture resistance is not critical to the application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8253F be used as a direct replacement for RK73H1HTTC8253F?

A: RK73H1HTTCM8253F matches all electrical and mechanical specifications. However, it lacks the moisture-resistant property of the original part. Use this substitute only if moisture resistance is not required by your application specifications.

Q: Is AC0201FR-07825KL a complete equivalent to RK73H1HTTC8253F?

A: Yes. AC0201FR-07825KL matches all electrical parameters (825 kOhms ±1%, 0.05W), mechanical specifications (0201 package), composition (thick film), temperature characteristics (±200ppm/°C, -55°C ~ 155°C), automotive qualification (AEC-Q200), moisture resistance, RoHS compliance (ROHS3), and MSL rating (MSL 1). It is a complete functional equivalent.

Q: Why is RK73H1HTTC8253F marked as Not For New Designs?

A: This designation indicates the part is in end-of-life status. For new designs, select from active alternatives such as AC0201FR-07825KL or RK73H1HTTCM8253F (if moisture resistance is not required).

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. Both RK73H1HTTCM8253F and AC0201FR-07825KL carry AEC-Q200 automotive qualification, meeting the same automotive reliability standards as the original part.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All parts listed maintain this rating.

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

A: Yes, all substitute parts use the identical 0201 (0603 Metric) package with matching footprint dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and height (0.010" / 0.26mm maximum). They are mechanically interchangeable in PCB assembly processes.

Q: What is the difference between RK73H1HTTC8253F and RK73H1HTTCM8253F?

A: The primary difference is moisture resistance. RK73H1HTTC8253F includes moisture-resistant properties, while RK73H1HTTCM8253F does not. All other electrical and mechanical parameters are identical.
