Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC8201F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 8.2 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 0201 (0603 Metric)
• Number of terminations: 2
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum seated height: 0.010" (0.26mm)

Compliance & Environmental Parameters:

• Automotive rating: AEC-Q200
• Composition: Thick Film
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Substitute parts must match all electrical specifications, mechanical dimensions, and compliance certifications. Deviations in any of these parameters result in incompatibility with the original design requirements.

Engineering Selection Recommendations

RK73H1HTTCM8201F (MFR Recommended Substitute): This part is the manufacturer-recommended alternative from KOA Speer Electronics, Inc. It maintains identical electrical specifications, mechanical dimensions, and automotive AEC-Q200 compliance. The primary distinction is active product status, making it suitable for new designs. However, moisture resistance is not explicitly specified in the provided data for this variant, which may be a consideration if moisture protection is critical to the application.

AC0201FR-078K2L (Direct Substitute): This YAGEO component provides full electrical and mechanical equivalence with explicit moisture-resistant construction. It carries active product status and maintains all required certifications including AEC-Q200, RoHS3 compliance, and MSL 1 rating. This part is suitable for direct substitution in applications requiring moisture-resistant thick film construction.

For new designs, either RK73H1HTTCM8201F or AC0201FR-078K2L is appropriate. Selection between these two should be based on supply chain availability, cost considerations, and any specific manufacturer preferences established in design guidelines. Both parts satisfy all electrical, mechanical, and compliance requirements of the original RK73H1HTTC8201F specification.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8201F be used as a direct replacement for RK73H1HTTC8201F? A: Yes. Both parts share identical resistance (8.2 kOhms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive rating. The primary difference is product status; RK73H1HTTCM8201F is active while the original is not for new designs.

Q: Is AC0201FR-078K2L electrically equivalent to RK73H1HTTC8201F? A: Yes. AC0201FR-078K2L matches all electrical parameters: 8.2 kOhms resistance, ±1% tolerance, 0.05W power rating, ±200ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. It also maintains AEC-Q200 compliance and identical 0201 package dimensions.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC8201F? A: This designation indicates the part is in mature or end-of-life phase. New circuit designs should utilize RK73H1HTTCM8201F or AC0201FR-078K2L, both of which carry active product status and ensure long-term supply availability.

Q: Are all three parts RoHS3 compliant? A: Yes. RK73H1HTTC8201F, RK73H1HTTCM8201F, and AC0201FR-078K2L are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Does moisture resistance differ between the substitute parts? A: RK73H1HTTC8201F and AC0201FR-078K2L both explicitly specify moisture-resistant construction. RK73H1HTTCM8201F does not include moisture resistance in its provided specification. If moisture protection is a design requirement, AC0201FR-078K2L or the original RK73H1HTTC8201F are preferred.

Q: Can these parts be used interchangeably in automated assembly? A: Yes. All three parts share identical 0201 (0603 Metric) package dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm), ensuring compatibility with standard pick-and-place equipment and PCB footprints.

Q: What certifications apply to all substitute parts? A: All three parts carry AEC-Q200 automotive qualification, ROHS3 compliance, REACH unaffected status, and MSL 1 rating. ECCN classification is EAR99 and HTSUS code is 8533.21.0030 for all parts.
