Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC36R0F is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 36 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 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria without exception. Substitutes are grouped into two categories: manufacturer-recommended alternatives from KOA Speer Electronics and direct cross-reference parts from alternative manufacturers.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM36R0F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains identical electrical and mechanical specifications to the main part while offering Active product status. Selection of this part is appropriate for designs requiring continuity within the KOA Speer RK73H series. The part is ROHS3 compliant and carries AEC-Q200 automotive qualification. Note that moisture resistance is not explicitly specified in the provided data for this variant.

AC0201FR-0736RL (YAGEO)

This part is a direct cross-reference alternative from YAGEO, offering identical electrical specifications, package dimensions, and automotive qualification. The AC0201FR-0736RL maintains Active product status and includes explicit moisture-resistant construction matching the original part. This component is suitable for applications where multi-source qualification is required or where YAGEO supply chain integration is preferred. ROHS3 compliance and AEC-Q200 rating are confirmed.

Both substitute parts are electrically and mechanically interchangeable with the RK73H1HTTC36R0F within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM36R0F be used as a direct replacement for RK73H1HTTC36R0F?

A: Yes. Both parts share identical resistance (36 Ohms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 qualification. The primary difference is product status: RK73H1HTTCM36R0F is Active while the original is Not For New Designs.

Q: What is the difference between RK73H1HTTC36R0F and AC0201FR-0736RL?

A: Both parts are electrically equivalent with matching resistance, tolerance, power rating, package, and automotive qualification. The primary difference is manufacturer: KOA Speer Electronics versus YAGEO. Both are ROHS3 compliant, MSL 1, and include moisture-resistant construction. AC0201FR-0736RL carries Active product status.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and operate across the -55°C ~ 155°C temperature range required for automotive environments.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical 0201 (0603 Metric) package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). They are mechanically and electrically interchangeable.

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

A: This designation indicates that RK73H1HTTC36R0F is in mature or end-of-life phase. For new designs, RK73H1HTTCM36R0F or AC0201FR-0736RL are recommended as both maintain Active status and identical specifications.

Q: Are moisture sensitivity considerations different between these parts?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
