Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2202F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 22 kOhms
• 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
• AEC-Q200 automotive qualification
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 compliance

All identified substitute parts meet these parameters without exception. Substitution is based on functional and environmental equivalence, not on product status or inventory availability.

Engineering Selection Recommendations

RK73H1HTTCM2202F (KOA Speer Electronics, Inc.):

This part is the manufacturer-recommended substitute within the KOA Speer RK73H series. It maintains identical electrical and mechanical specifications to the RK73H1HTTC2202F while carrying Active product status. Both parts share the same series designation (RK73H) and are manufactured by the same supplier. This substitute is appropriate for applications requiring continuity within the KOA Speer product line and for new production runs where the original part is no longer available.

AC0201FR-0722KL (YAGEO):

This part is a direct cross-reference substitute from YAGEO's AC series. It provides functional and environmental equivalence across all critical parameters, including AEC-Q200 automotive qualification, identical resistance, tolerance, power rating, and package specifications. The AC0201FR-0722KL carries Active product status and represents a qualified alternative from a different manufacturer. This substitute is suitable for applications where multi-source component strategies are required or where YAGEO supply chain availability is preferred.

Both substitutes are fully compliant with ROHS3 regulations, maintain MSL 1 (Unlimited) moisture sensitivity ratings, and operate across the identical temperature range. Selection between these substitutes should be based on supply chain requirements, procurement preferences, and existing qualification documentation for the target application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2202F be used as a direct replacement for RK73H1HTTC2202F in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance (22 kOhms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM2202F is Active, while RK73H1HTTC2202F is Not For New Designs.

Q: What is the difference between RK73H1HTTC2202F and RK73H1HTTCM2202F?

A: Both parts are manufactured by KOA Speer Electronics and belong to the RK73H series. The designations differ in their product lifecycle status. RK73H1HTTCM2202F is the current Active production variant, while RK73H1HTTC2202F is designated Not For New Designs. All electrical, mechanical, and environmental specifications are identical.

Q: Can AC0201FR-0722KL from YAGEO replace the KOA part in automotive applications?

A: Yes. AC0201FR-0722KL meets all equivalent specifications including AEC-Q200 automotive qualification, identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. It is suitable for automotive applications where the original KOA part was specified.

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

A: No. All three parts use the 0201 package (0603 Metric) with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are footprint-compatible and require no PCB layout modifications.

Q: Do all substitutes maintain the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Which substitute should be selected for new production designs?

A: Either RK73H1HTTCM2202F or AC0201FR-0722KL is appropriate for new production, as both carry Active product status. Selection should be based on supply chain strategy, existing supplier relationships, and procurement cost considerations. Both parts are fully qualified for automotive applications.
