Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC1650F is determined by strict equivalence across the following parameters:

Electrical Specifications: Resistance value (165 Ohms), tolerance (±1%), and power rating (0.05W) must be identical. Temperature coefficient (±200ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package format must be 0201 (0603 Metric) with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and height (0.010" maximum seated height / 0.26mm).

Composition & Construction: Thick film construction is required. Moisture-resistant properties must be maintained.

Compliance & Ratings: AEC-Q200 automotive qualification is mandatory. RoHS3 compliance and MSL 1 rating must be present. REACH unaffected status applies to all identified substitutes.

Substitutes are grouped by manufacturer origin and packaging configuration while maintaining all electrical and mechanical equivalence criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RK73H1HTTC1650F): This KOA Speer part maintains full specification equivalence with moisture-resistant properties and Tape & Reel packaging. Suitable for direct component replacement in automotive applications requiring AEC-Q200 compliance.

Manufacturer Alternative (RK73H1HTTCM1650F): This KOA Speer variant provides identical electrical and thermal specifications with higher inventory availability (1114 units). Note that moisture-resistant properties are not specified for this variant. Selection should account for application moisture exposure requirements. Packaging configuration is not specified.

Cross-Manufacturer Substitute (AC0201FR-07165RL): The YAGEO AC series part provides complete electrical, mechanical, and compliance equivalence with moisture-resistant construction and Tape & Reel packaging. All AEC-Q200, RoHS3, and MSL 1 requirements are met. This part is suitable for applications where manufacturer diversification is acceptable.

All three parts maintain active production status and are immediately available for procurement.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1650F be used as a direct replacement for RK73H1HTTC1650F?

A: Electrical and thermal specifications are identical. However, moisture-resistant properties are not specified for the RK73H1HTTCM1650F variant. Selection depends on application environment. Both parts carry AEC-Q200 qualification and RoHS3 compliance. Packaging configuration differs (not specified versus Tape & Reel).

Q: Is AC0201FR-07165RL from YAGEO fully compatible with the KOA RK73H1HTTC1650F?

A: Yes. The YAGEO AC0201FR-07165RL meets all electrical specifications (165 Ohms ±1%, 0.05W), mechanical dimensions (0201 package), thermal performance (±200ppm/°C, -55°C ~ 155°C), and automotive compliance (AEC-Q200). Moisture-resistant properties and Tape & Reel packaging are present on both parts.

Q: What determines whether a part can substitute for RK73H1HTTC1650F?

A: Substitution requires matching resistance value (165 Ohms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Moisture resistance and RoHS3 compliance are required attributes.

Q: Are all substitute parts available in Tape & Reel packaging?

A: RK73H1HTTC1650F and AC0201FR-07165RL are confirmed Tape & Reel (TR) packaged. RK73H1HTTCM1650F packaging configuration is not specified in available data.

Q: Do all parts meet automotive qualification standards?

A: Yes. RK73H1HTTC1650F, RK73H1HTTCM1650F, and AC0201FR-07165RL all carry AEC-Q200 automotive qualification ratings.

Q: What is the difference in moisture handling between these parts?

A: RK73H1HTTC1650F and AC0201FR-07165RL are specified as moisture-resistant. RK73H1HTTCM1650F does not specify moisture-resistant properties. All three parts carry MSL 1 (Unlimited) moisture sensitivity level ratings.
