Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC2000D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Temperature coefficient: ±200ppm/°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 reliability)

Substitute parts must match all electrical and mechanical parameters without exception. Variations in product status (Active vs. Not For New Designs) do not affect functional substitutability but indicate design lifecycle positioning.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM2000D is a direct functional equivalent to the RK73H1HTTC2000D. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73H series, and share identical electrical specifications, mechanical dimensions, and compliance certifications.

Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and high-reliability applications without additional qualification requirements.

The difference in product status does not affect electrical performance, thermal characteristics, or mechanical fit. Selection between these parts should be based on supply chain requirements and design lifecycle considerations.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2000D replace RK73H1HTTC2000D in existing designs?

A: Yes. The RK73H1HTTCM2000D is electrically and mechanically identical to the RK73H1HTTC2000D. All critical parameters—resistance, tolerance, power rating, package dimensions, temperature range, and automotive certification—are equivalent. Direct substitution is supported without circuit redesign or re-qualification.

Q: What is the significance of "Not For New Designs" status on the RK73H1HTTC2000D?

A: "Not For New Designs" indicates the part is in the mature or end-of-life phase of its product lifecycle. Existing designs using this part remain supported, but new designs should utilize the RK73H1HTTCM2000D, which carries Active status and ensures long-term availability.

Q: Are there any differences in moisture handling between these parts?

A: No. Both the RK73H1HTTC2000D and RK73H1HTTCM2000D are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Both incorporate moisture-resistant thick film construction and are suitable for standard storage and handling without special precautions.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance. They are suitable for automotive applications without additional testing or certification.

Q: What is the physical footprint compatibility?

A: Both parts use the 0201 package (0603 Metric) with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB layout and assembly processes require no modification.

Q: Are there packaging differences between these parts?

A: The RK73H1HTTC2000D is specified as Tape & Reel (TR) packaging. The RK73H1HTTCM2000D packaging specification is not provided in the available data. Confirm packaging requirements with the supplier before procurement.
