Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2940F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 294 Ohms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture resistance: Required
• RoHS compliance: ROHS3
• Moisture sensitivity level: MSL 1

All identified substitute parts meet these parameters without exception. Substitutes are grouped into two categories:

Category 1 - Manufacturer Recommended: RK73H1HTTCM2940F (KOA Speer Electronics, Inc.) - Same manufacturer, active product status, identical electrical and mechanical specifications.

Category 2 - Direct Equivalent: AC0201FR-07294RL (YAGEO) - Alternative manufacturer, active product status, identical electrical and mechanical specifications with equivalent automotive and moisture-resistant certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production: Select RK73H1HTTCM2940F (KOA Speer Electronics, Inc.) as the primary substitute. This part carries active product status from the original manufacturer, ensuring long-term supply availability and design support. It maintains identical electrical specifications and automotive AEC-Q200 qualification.

For Cross-Manufacturer Sourcing: AC0201FR-07294RL (YAGEO) serves as a qualified direct equivalent for applications requiring supply chain diversification. This part is active, meets all electrical and mechanical requirements, and carries equivalent automotive and moisture-resistant certifications. Use this option when KOA Speer supply is constrained or when multi-source qualification is required.

For Existing Inventory Management: The RK73H1HTTC2940F may continue to be used in existing production runs where stock is available (38,398 pcs in inventory). However, new design initiation should transition to RK73H1HTTCM2940F to align with active product lifecycle management.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2940F be used as a direct replacement for RK73H1HTTC2940F? A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share identical resistance (294 Ohms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM2940F is active, while RK73H1HTTC2940F is not for new designs.

Q: Is AC0201FR-07294RL compatible with designs specified for RK73H1HTTC2940F? A: Yes. AC0201FR-07294RL meets all critical electrical and mechanical parameters: 294 Ohms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 automotive qualification. Both parts feature moisture-resistant thick film construction and MSL 1 rating. The manufacturer difference (YAGEO vs. KOA Speer) does not affect functional compatibility.

Q: What is the significance of the "Not For New Designs" status? A: This designation indicates that RK73H1HTTC2940F has been superseded in the manufacturer's product line. While existing inventory may be used for ongoing production, new design initiatives should specify RK73H1HTTCM2940F to ensure long-term supply continuity and manufacturer support.

Q: Are there packaging differences between the substitute parts? A: RK73H1HTTC2940F and AC0201FR-07294RL are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM2940F packaging is not specified in available documentation. Confirm packaging requirements with the supplier before procurement.

Q: Do all substitute parts meet automotive AEC-Q200 requirements? A: Yes. RK73H1HTTCM2940F and AC0201FR-07294RL both carry AEC-Q200 qualification, meeting automotive reliability and qualification standards equivalent to the main part.

Q: What is the moisture sensitivity level for these parts? A: All three parts (main and substitutes) carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements under normal storage conditions.
