Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC4752F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 47.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 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: Present (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RK73H1HTTC4752F in applications where these specifications are required.

Engineering Selection Recommendations

RK73H1HTTCM4752F (KOA Speer Electronics, Inc. - MFR Recommended)

This part is the manufacturer-recommended substitute for the RK73H1HTTC4752F. It carries an Active product status, indicating ongoing manufacturing and supply availability. All electrical and mechanical parameters are identical to the original part. This option is preferred for new procurement and design updates where KOA supply chain continuity is prioritized.

AC0201FR-0747K5L (YAGEO - Direct Equivalent)

This part is a direct electrical and mechanical equivalent manufactured by YAGEO. It maintains Active product status with higher current inventory availability (20,973 Pcs in stock). All specified parameters match the original component exactly. This option is suitable for applications where multi-source component qualification is acceptable and YAGEO supply chain access is preferred.

Both substitute parts satisfy all compliance requirements including AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. Selection between these options should be based on established supplier relationships, supply chain strategy, and design documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM4752F be used as a direct replacement for RK73H1HTTC4752F?

A: Yes. The RK73H1HTTCM4752F is the manufacturer-recommended substitute. All electrical parameters (47.5 kOhms, ±1% tolerance, 0.05W power rating, ±200ppm/°C temperature coefficient), mechanical dimensions (0201 package, 0.024" L x 0.012" W), and compliance ratings (AEC-Q200, ROHS3, MSL 1) are identical. The primary difference is product status: RK73H1HTTCM4752F is Active while the original is Not For New Designs.

Q: Is AC0201FR-0747K5L compatible with designs specified for RK73H1HTTC4752F?

A: Yes. The AC0201FR-0747K5L meets all electrical and mechanical specifications required for substitution. Resistance, tolerance, power rating, package format, temperature coefficient, operating temperature range, and all compliance certifications are identical. The component is manufactured by YAGEO rather than KOA Speer Electronics, Inc., but maintains equivalent performance characteristics.

Q: What are the key parameters that determine substitutability for this 0201 resistor?

A: Substitutability is determined by exact matching of: resistance value (47.5 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 qualification (AEC-Q200), moisture resistance, RoHS compliance (ROHS3), and moisture sensitivity level (MSL 1). Any deviation in these parameters disqualifies a part from direct substitution.

Q: Why is the original RK73H1HTTC4752F marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's active product line. The RK73H1HTTCM4752F serves as the active replacement. Existing designs using RK73H1HTTC4752F remain supported, but new designs should specify the active equivalent to ensure long-term supply availability and manufacturing continuity.

Q: Are there any packaging differences between these three parts?

A: All three parts use identical 0201 (0603 Metric) package format with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). The RK73H1HTTC4752F and AC0201FR-0747K5L are supplied in Tape & Reel (TR) packaging. Packaging information for RK73H1HTTCM4752F is not specified in available data.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability and quality standards. They are suitable for automotive circuit applications where this qualification is required. MSL 1 rating indicates unlimited shelf life without moisture sensitivity concerns.
