Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC10R7F are qualified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 10.7 Ohms (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 compliance: 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)

Substitutes are grouped into two categories: manufacturer-recommended alternatives and direct cross-reference parts from alternative suppliers. All identified substitutes maintain identical electrical performance, thermal characteristics, and environmental ratings.

Engineering Selection Recommendations

RK73H1HTTCM10R7F (KOA Speer Electronics, Inc.) - Manufacturer-Recommended Substitute

This part represents the active-status successor within KOA's RK73H series. It maintains identical electrical specifications, thermal performance, and automotive compliance as the original RK73H1HTTC10R7F. The primary distinction is product status: RK73H1HTTCM10R7F is classified as Active, making it the preferred choice for new designs and ongoing production. Both parts share the same series designation (RK73H) and are manufactured by the same supplier, ensuring process consistency and supply chain continuity. Current inventory availability is 1090 pieces.

AC0201FR-0710R7L (YAGEO) - Direct Cross-Reference Substitute

This YAGEO component provides an alternative from a different manufacturer while maintaining complete electrical and mechanical equivalence. The AC0201FR-0710R7L meets all specified parameters including 10.7 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package format, AEC-Q200 automotive rating, and moisture-resistant thick film construction. This part is classified as Active and carries current inventory of 1142 pieces. Selection of this substitute is appropriate when supply diversification or YAGEO-specific supply chain requirements are factors.

Both substitutes are fully qualified replacements based on identical compliance certifications (ROHS3, AEC-Q200, MSL 1) and matching environmental operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM10R7F be used as a direct replacement for RK73H1HTTC10R7F in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 10.7 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 rating, and moisture-resistant thick film construction. The primary difference is product status; RK73H1HTTCM10R7F is Active while the original is Not For New Designs.

Q: What is the difference between RK73H1HTTC10R7F and RK73H1HTTCM10R7F?

A: Both parts are from KOA's RK73H series with identical electrical and mechanical specifications. The designation difference (HTTC vs. HTTCM) reflects manufacturing or packaging variations within KOA's product line, but all critical parameters remain equivalent. RK73H1HTTCM10R7F is the current active product.

Q: Can YAGEO AC0201FR-0710R7L replace KOA parts in automotive applications?

A: Yes. The AC0201FR-0710R7L meets all automotive requirements including AEC-Q200 certification, identical operating temperature range (-55°C to 155°C), and equivalent electrical specifications. It is suitable for automotive applications where the original KOA part was specified.

Q: Are there any package or footprint differences between these three parts?

A: No. All three parts use the 0201 (0603 Metric) package format with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints are interchangeable.

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

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life under standard storage conditions and do not require special moisture-control handling or baking procedures prior to soldering.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: Which part should be selected for new design work?

A: For new designs, either RK73H1HTTCM10R7F (KOA, Active status) or AC0201FR-0710R7L (YAGEO, Active status) are appropriate selections. The original RK73H1HTTC10R7F is designated Not For New Designs and should not be used in new development.
