Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC3003F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 300 kOhms (exact match required)
• Tolerance: ±1% (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 match all electrical, mechanical, and compliance parameters without exception. Differences in product status (Active vs. Not For New Designs) do not affect functional equivalence but indicate manufacturing lifecycle stage.

Parameter Comparison

Engineering Selection Recommendations

RK73G1HTTCM3003F is the direct equivalent substitute for RK73G1HTTC3003F.

Substitution Basis:

The RK73G1HTTCM3003F maintains complete electrical and mechanical equivalence with the main part across all specified parameters. Both components are manufactured by KOA Speer Electronics, Inc., belong to the RK73G series, and deliver identical performance characteristics: 300 kOhms resistance at ±1% tolerance, 0.05W power rating, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range.

Compliance Alignment:

Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 rating, ensuring regulatory adherence and compatibility with automotive supply chain requirements.

Product Status Consideration:

The substitute part RK73G1HTTCM3003F holds "Active" product status, indicating ongoing manufacturer support and availability. The main part RK73G1HTTC3003F is designated "Not For New Designs," reflecting its superseded lifecycle stage. Selection of the Active substitute ensures long-term supply chain continuity and access to current manufacturing processes.

Packaging & Handling:

Both components utilize identical 0201 (0603 Metric) package dimensions and termination configuration, ensuring direct PCB compatibility without layout or assembly modifications.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM3003F replace RK73G1HTTC3003F in existing designs?

A: Yes. The RK73G1HTTCM3003F is a direct functional equivalent with identical electrical specifications (300 kOhms ±1%, 0.05W, ±50ppm/°C), mechanical package (0201 / 0603 Metric), and automotive certifications (AEC-Q200). No circuit modifications or PCB redesign is required.

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

A: The primary difference is product lifecycle status. RK73G1HTTC3003F is "Not For New Designs," while RK73G1HTTCM3003F is "Active." All electrical, mechanical, and compliance parameters are identical. The suffix variation in the part number reflects the manufacturer's product line evolution.

Q: Are both parts suitable for automotive applications?

A: Yes. Both RK73G1HTTC3003F and RK73G1HTTCM3003F carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry standards for reliability and environmental conformance.

Q: Can I mix these parts in the same production batch?

A: Yes. Identical electrical and mechanical specifications allow interchangeability. Both parts meet the same performance and compliance requirements, supporting mixed-lot assembly without functional or reliability impact.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the RK73G1HTTC3003F has been superseded in the manufacturer's active product portfolio. While existing inventory remains available, new designs should transition to the Active equivalent RK73G1HTTCM3003F to ensure long-term supply availability and manufacturer support.

Q: Are there any handling or storage differences between these parts?

A: No. Both components share identical Moisture Sensitivity Level 1 (Unlimited) rating, requiring no special moisture control during storage or handling. Standard ESD precautions and dry storage conditions apply equally to both parts.

Q: What certifications apply to both parts?

A: Both RK73G1HTTC3003F and RK73G1HTTCM3003F are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. AEC-Q200 automotive qualification applies to both.
