Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC7682F is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 76.8 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Package format: 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
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these parameters without exception. Substitutes are classified into two categories: manufacturer-recommended alternatives from KOA Speer Electronics and direct cross-reference parts from alternative manufacturers that provide identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM7682F (KOA Speer Electronics, Inc. - Manufacturer Recommended)

This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains identical electrical specifications and package format while offering Active product status. Selection of this part ensures continuity with the original manufacturer's product line and design intent. The part is ROHS3 compliant and carries AEC-Q200 automotive qualification. Moisture resistance specification is not explicitly stated for this variant, which represents a minor deviation from the original part documentation.

AC0201FR-0776K8L (YAGEO - Direct Cross-Reference)

This YAGEO part provides a direct cross-reference alternative with full electrical and mechanical equivalence to the original RK73H1HTTC7682F. It maintains all critical parameters including 76.8 kOhms resistance, ±1% tolerance, 0.05W power rating, 0201 package format, AEC-Q200 automotive qualification, and moisture-resistant thick film construction. The part carries Active product status and ROHS3 compliance. This option is suitable for applications requiring multi-source component availability or where YAGEO supply chain integration is preferred.

Both substitute parts are qualified for direct replacement in applications currently using the RK73H1HTTC7682F without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7682F be used as a direct replacement for RK73H1HTTC7682F?

A: Yes. Both parts share identical resistance (76.8 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM7682F is Active while the original is Not For New Designs.

Q: What is the difference between RK73H1HTTC7682F and AC0201FR-0776K8L?

A: Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, composition, temperature coefficient, and operating temperature range. The primary differences are manufacturer (KOA Speer vs. YAGEO) and product status (Not For New Designs vs. Active). Both carry AEC-Q200 qualification and ROHS3 compliance.

Q: Are all substitute parts suitable for automotive applications?

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

Q: Does package format remain identical across all substitutes?

A: Yes. All substitute parts use the 0201 (0603 Metric) package format with identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm).

Q: Are moisture-resistant properties maintained in all substitutes?

A: The AC0201FR-0776K8L explicitly specifies moisture-resistant construction. The RK73H1HTTCM7682F does not explicitly state moisture resistance in the provided documentation, though both parts maintain MSL 1 (Unlimited) rating.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates precision-grade resistor performance. All substitute parts maintain this tolerance specification, ensuring equivalent circuit performance and accuracy in applications requiring tight resistance value control.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts maintain electrical equivalence across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Physical package dimensions are identical, enabling direct PCB footprint compatibility without layout modifications.
