Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H1HTTC8063F are qualified based on the following criteria:

Electrical Parameters: Resistance value (806 kOhms), tolerance (±1%), power rating (0.05W), and temperature coefficient (±200ppm/°C) must be identical.

Mechanical Parameters: Package format (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and maximum seated height (0.010" / 0.26mm) must match exactly.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), automotive AEC-Q200 qualification, RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained.

Composition & Features: Thick film construction and moisture-resistant properties must be present.

Substitutes are grouped into two categories: manufacturer-recommended alternatives from KOA Speer Electronics and direct cross-references from alternative manufacturers meeting identical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RK73H1HTTC8063F remains the baseline reference part with the highest inventory availability (1007 units) and explicit moisture-resistant specification. All electrical, mechanical, and compliance parameters are fully documented.

Manufacturer-Recommended Alternative: RK73H1HTTCM8063F is an active KOA Speer Electronics part meeting all core electrical and mechanical specifications with AEC-Q200 automotive qualification and RoHS3 compliance. This part is suitable for direct substitution in applications where moisture resistance is not explicitly required in the design specification. Inventory availability is 743 units.

Cross-Manufacturer Alternative: AC0201FR-07806KL from YAGEO meets all electrical specifications, mechanical dimensions, automotive AEC-Q200 qualification, and RoHS3 compliance. This part includes explicit moisture-resistant construction matching the primary part. Inventory availability is 800 units. This part is suitable for applications requiring multi-source qualification or when KOA Speer Electronics parts are unavailable.

All three parts maintain identical operating temperature ranges (-55°C ~ 155°C), temperature coefficients (±200ppm/°C), and MSL ratings (1 - Unlimited), ensuring functional equivalence in automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8063F be used as a direct replacement for RK73H1HTTC8063F?

A: RK73H1HTTCM8063F is electrically and mechanically equivalent to RK73H1HTTC8063F. Both parts share identical resistance (806 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), and automotive AEC-Q200 qualification. The primary difference is that moisture resistance is not specified for the RK73H1HTTCM8063F variant. If moisture resistance is a design requirement, the original RK73H1HTTC8063F or AC0201FR-07806KL should be specified.

Q: Is AC0201FR-07806KL from YAGEO compatible with designs using RK73H1HTTC8063F?

A: AC0201FR-07806KL is fully compatible. It matches all critical parameters: 806 kOhms ±1% resistance, 0.05W power rating, 0201 package format, -55°C ~ 155°C operating temperature range, ±200ppm/°C temperature coefficient, AEC-Q200 automotive qualification, RoHS3 compliance, and moisture-resistant construction. Physical dimensions and MSL ratings are identical.

Q: What is the difference between the 0201 package designation and 0603 Metric?

A: 0201 and 0603 Metric refer to the same physical package format. 0201 is the imperial designation (0.024" L x 0.012" W), while 0603 Metric is the metric equivalent (0.60mm x 0.30mm). All three parts use this identical package format.

Q: Are all three parts suitable for automotive applications?

A: All three parts carry AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability and quality standards. All are suitable for automotive applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These parts do not require special moisture control during storage, handling, or assembly. They can be stored and used without time-limited exposure restrictions.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All three parts meet RoHS3 compliance and carry AEC-Q200 automotive qualification. They are functionally equivalent for high-reliability applications. Selection should be based on design-specific requirements such as moisture resistance specification, manufacturer preference, and inventory availability.
