Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC4702D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 47 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory adherence)
• Moisture Sensitivity Level 1 (required for handling and storage compatibility)

Substitute parts must satisfy all parameters listed above. The RK73G1HTTCM4702D meets these criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RK73G1HTTCM4702D

The RK73G1HTTCM4702D is the manufacturer-recommended substitute for the RK73G1HTTC4702D. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series and share identical electrical and mechanical specifications. The substitute part carries "Active" product status, ensuring long-term availability and continued manufacturer support.

Compliance Alignment:

Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. No compliance gaps exist between the main part and substitute. The transition from RK73G1HTTC4702D to RK73G1HTTCM4702D does not introduce regulatory or certification risks.

Supply Chain Consideration:

The RK73G1HTTCM4702D is actively produced and supported by the manufacturer, whereas the RK73G1HTTC4702D is designated "Not For New Designs." For applications requiring long-term component availability and manufacturer technical support, the substitute part is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM4702D be used as a direct replacement for RK73G1HTTC4702D in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (47 kOhms), tolerance (±0.5%), power rating (0.05W), package (0201), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). No circuit redesign or board layout modification is required.

Q: What is the difference between these two part numbers?

A: The RK73G1HTTC4702D is designated "Not For New Designs" by the manufacturer, while RK73G1HTTCM4702D carries "Active" status. The substitute part represents the current production equivalent within the RK73G series. Both parts are functionally identical.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both RK73G1HTTC4702D and RK73G1HTTCM4702D carry AEC-Q200 automotive qualification, confirming suitability for automotive applications requiring this certification.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the 0201 package compatible with standard PCB assembly equipment?

A: The 0201 (0603 Metric) package is a standard surface-mount component package. Compatibility depends on specific assembly equipment capabilities. Verify that your manufacturing partner supports 0201 component placement and soldering processes.

Q: Can I mix inventory of both part numbers in production?

A: Yes. Since both parts are electrically and mechanically identical with matching compliance certifications, they can be used interchangeably in the same application without functional or reliability impact.
