Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC9313F are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Resistance value: 931 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)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the main part in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM9313F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains the same series designation (RK73H) and carries an Active product status, indicating ongoing manufacturer support. All electrical and mechanical parameters are identical to the main part. This option is preferred for designs requiring continuity within the KOA product family and for applications where manufacturer lineage is a selection criterion.

AC0201FR-07931KL (YAGEO): This part is a direct cross-reference alternative from YAGEO, a qualified automotive resistor manufacturer. It carries Active product status and meets all electrical and mechanical specifications. The AC0201FR-07931KL includes moisture-resistant construction matching the original part specification. This option provides supply chain diversification and is suitable for applications where multi-source qualification is required or where YAGEO components are already qualified in the design.

Both substitutes are fully compliant with AEC-Q200 automotive standards, ROHS3 regulations, and MSL 1 moisture sensitivity requirements, making them suitable for direct replacement in automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM9313F be used as a direct replacement for RK73H1HTTC9313F?

A: Yes. The RK73H1HTTCM9313F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It matches all electrical parameters (931 kOhms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C), mechanical specifications (0201 package), and compliance certifications (AEC-Q200, ROHS3, MSL 1). The primary difference is product status: RK73H1HTTCM9313F is Active, while the original is Not For New Designs.

Q: Is AC0201FR-07931KL electrically equivalent to RK73H1HTTC9313F?

A: Yes. The AC0201FR-07931KL from YAGEO meets all electrical and mechanical requirements: 931 kOhms ±1%, 0.05W power rating, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, 0201 package, AEC-Q200 qualification, ROHS3 compliance, and MSL 1 rating. It is a qualified substitute for automotive applications.

Q: What is the significance of "Not For New Designs" status on the main part?

A: "Not For New Designs" indicates that KOA Speer Electronics, Inc. has discontinued active development and support for this specific part number. While existing inventory remains available, the manufacturer recommends using the Active alternative (RK73H1HTTCM9313F) for new designs to ensure long-term supply availability and continued manufacturer support.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, which is the automotive industry standard for discrete semiconductors and passive components. They are suitable for automotive-grade applications requiring this certification.

Q: What is the difference between the packaging specifications listed?

A: RK73H1HTTC9313F and AC0201FR-07931KL are specified as Tape & Reel (TR) packaging, which is standard for high-volume automated assembly. RK73H1HTTCM9313F does not specify packaging format in the provided data. For procurement purposes, confirm packaging requirements with the supplier, as this affects handling, storage, and assembly processes.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not have specific manufacturer or series requirements. All three parts meet identical electrical specifications (931 kOhms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C), mechanical dimensions (0201 package), and compliance standards (AEC-Q200, ROHS3, MSL 1). Substitution is valid from an engineering standpoint.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 rating have unlimited shelf life and do not require special moisture-control storage or handling procedures. All three parts carry this rating, simplifying inventory management and logistics.
