Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Preferred): RK73H1HTTC6190F remains the specified component with confirmed Active product status, full moisture-resistant specification, and established supply availability at 790 units.

Manufacturer-Recommended Substitute: RK73H1HTTCM6190F is a KOA Speer Electronics variant within the same RK73H series. This part maintains identical electrical and mechanical specifications with higher inventory availability (1064 units). Note that moisture resistance is not explicitly specified for this variant, though it shares the same series designation and AEC-Q200 qualification.

Cross-Manufacturer Equivalent: AC0201FR-07619RL manufactured by YAGEO provides direct electrical and mechanical equivalence with confirmed moisture-resistant construction and AEC-Q200 automotive qualification. This part is available in Tape & Reel packaging with 1173 units in stock. Selection of this substitute is appropriate when KOA supply is constrained or when multi-source qualification is required.

All three parts satisfy identical electrical performance requirements, package compatibility, and automotive compliance standards.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6190F be used as a direct replacement for RK73H1HTTC6190F?

A: RK73H1HTTCM6190F shares identical electrical specifications (619 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C) and mechanical dimensions (0201 package, 0.024" L x 0.012" W). Both parts are AEC-Q200 qualified and RoHS3 compliant. The primary difference is that moisture resistance is not explicitly specified for the M variant, though both are MSL 1 rated. Substitution is valid for applications where the original moisture-resistant specification is not a critical design requirement.

Q: Is AC0201FR-07619RL from YAGEO fully compatible with the KOA RK73H1HTTC6190F?

A: Yes. AC0201FR-07619RL provides complete electrical equivalence (619 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C) and mechanical compatibility (0201 package, identical dimensions). Both parts feature moisture-resistant thick film construction, AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating. The component is suitable for direct substitution in automotive applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Identical resistance value and tolerance (619 Ohms ±1%); (2) Identical power rating (0.05W); (3) Identical package format and physical dimensions (0201, 0.024" L x 0.012" W); (4) Identical temperature coefficient (±200ppm/°C) and operating range (-55°C ~ 155°C); (5) Automotive AEC-Q200 qualification; (6) Thick film composition; (7) RoHS3 compliance; (8) MSL 1 rating. Moisture resistance is specified for the primary part and AC0201FR-07619RL but not explicitly stated for RK73H1HTTCM6190F.

Q: Are there packaging format differences between these substitutes?

A: RK73H1HTTC6190F and AC0201FR-07619RL are both supplied in Tape & Reel (TR) format. RK73H1HTTCM6190F packaging format is not specified in available documentation. All three parts use identical 0201 (0603 Metric) package format with matching physical dimensions, ensuring mechanical compatibility on PCB assemblies regardless of packaging format.

Q: What is the significance of AEC-Q200 qualification for these parts?

A: AEC-Q200 is the automotive industry standard qualification for passive components, including resistors. All three substitute parts carry this qualification, confirming suitability for automotive applications with specified reliability, temperature cycling, and environmental stress testing requirements. This qualification is mandatory for automotive-grade circuit designs.

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

A: All three parts meet identical electrical specifications and carry AEC-Q200 automotive qualification with RoHS3 compliance. Interchangeability in high-reliability applications is supported by matching specifications. However, design documentation should reflect the specific part number used, and any moisture-sensitive application requirements should be verified against the moisture-resistant specification explicitly stated for each part.
