Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC6801F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 6.8 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)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height - Seated (Max): 0.010" (0.26mm) (exact match required)

Compliance & Certification:

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

Substitute parts must match all parameters listed above. Deviations in any electrical, mechanical, or compliance specification disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM6801F is a direct electrical and mechanical equivalent to the RK73G1HTTC6801F. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73G series and share identical specifications across all critical parameters: 6.8 kOhms resistance, ±1% tolerance, 0.05W power rating, ±50ppm/°C temperature coefficient, -55°C to 155°C operating range, and 0201 package dimensions.

The primary distinction is product status: the main part (RK73G1HTTC6801F) is designated "Not For New Designs," while the substitute (RK73G1HTTCM6801F) maintains "Active" status. Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 rating, ensuring compatibility in automotive and regulated applications.

The substitute part is suitable for direct replacement in existing designs, production continuity, and maintenance applications where the main part is no longer available through standard procurement channels.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM6801F be used as a direct replacement for RK73G1HTTC6801F?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) and mechanical specifications (package, dimensions, height) match exactly. Both carry AEC-Q200 automotive qualification and ROHS3 compliance.

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

A: The primary difference is product lifecycle status. RK73G1HTTC6801F is classified "Not For New Designs," while RK73G1HTTCM6801F is "Active." The "M" designation in the substitute part number indicates an active production variant. All functional and compliance specifications remain identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RK73G1HTTC6801F and RK73G1HTTCM6801F meet AEC-Q200 automotive qualification standards and are rated for the full automotive temperature range of -55°C to 155°C.

Q: Can I use these parts interchangeably on PCBs?

A: Yes. Both parts share identical 0201 (0603 Metric) package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). They are mechanically and electrically interchangeable for PCB assembly.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Are these parts RoHS compliant?

A: Yes. Both RK73G1HTTC6801F and RK73G1HTTCM6801F are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for restricted substance compliance.
