Substitute Part Grouping Explanation

Substitution of the RK73H1HTTC95R3F is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 95.3 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

Substitute parts must match all critical parameters without exception. Manufacturer differences are acceptable provided all electrical and mechanical specifications remain identical. Product status (Active vs. Not For New Designs) does not affect substitution eligibility but influences availability and long-term support considerations.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM95R3F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. It maintains identical electrical specifications and AEC-Q200 automotive qualification. The primary distinction is active product status, ensuring continued manufacturing support and availability. This substitute is preferred for new production runs and long-term supply chain stability. Note that moisture resistance is not explicitly specified in the provided data for this variant.

AC0201FR-0795R3L (YAGEO): This part is a direct cross-reference from YAGEO and provides full electrical and mechanical equivalence to the original RK73H1HTTC95R3F. It carries active product status, AEC-Q200 qualification, and explicit moisture-resistant construction. The AC series from YAGEO meets all critical parameters and is suitable for direct substitution in automotive applications. Current inventory levels support immediate procurement.

Both substitute parts are ROHS3 compliant, MSL 1 rated, and operate across the identical temperature range (-55°C ~ 155°C). Selection between them should be based on existing supply chain relationships, procurement lead times, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM95R3F replace RK73H1HTTC95R3F in existing designs? A: Yes. Both parts share identical electrical specifications (95.3 Ohms ±1%, 0.05W), package geometry (0201), and AEC-Q200 automotive qualification. The primary difference is product status; RK73H1HTTCM95R3F is active while the original is not for new designs.

Q: Is YAGEO AC0201FR-0795R3L a suitable substitute? A: Yes. The AC0201FR-0795R3L meets all critical electrical and mechanical parameters: 95.3 Ohms ±1%, 0.05W, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 qualification. It is an active product with moisture-resistant construction.

Q: What are the key parameters that must match for substitution? A: Resistance (95.3 Ohms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification are non-negotiable. Moisture resistance and RoHS compliance must also be maintained.

Q: Does package size differ between these parts? A: No. All three parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: Are there compliance or certification differences? A: All three parts are ROHS3 compliant, MSL 1 rated, and AEC-Q200 qualified. REACH status is unaffected for all parts. ECCN classification is EAR99 for all variants.

Q: What is the difference between RK73H1HTTC95R3F and RK73H1HTTCM95R3F? A: The primary difference is product status: RK73H1HTTC95R3F is "Not For New Designs" while RK73H1HTTCM95R3F is "Active." Electrical and mechanical specifications are identical. Moisture resistance is explicitly stated for the original but not specified for the M variant in the provided data.

Q: Which substitute should I choose for new production? A: For new designs, either RK73H1HTTCM95R3F or AC0201FR-0795R3L is appropriate. Both are active products with full AEC-Q200 qualification. Selection should be based on supply chain availability, lead times, and procurement preferences.
