Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC2003D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 200 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)
• 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)
• Number of terminations: 2 (exact match required)

Compliance & Certification:

• Composition: Thick Film (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical interchangeability in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2003D is the manufacturer-recommended substitute for the RK73G1HTTC2003D. Both components are manufactured by KOA Speer Electronics, Inc., and belong to the RK73G series. The substitute part maintains complete electrical and mechanical equivalence across all specified parameters.

The primary distinction between the main part and substitute is product status: the RK73G1HTTC2003D carries "Not For New Designs" classification, while the RK73G1HTTCM2003D is designated as "Active." This status difference reflects manufacturing lifecycle positioning and does not indicate any technical deficiency in the original part.

Both components satisfy identical compliance requirements:

• AEC-Q200 automotive qualification
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status
• EAR99 ECCN classification

For new design implementations and ongoing production, the RK73G1HTTCM2003D is the appropriate selection due to its active product status. Existing designs utilizing the RK73G1HTTC2003D may continue operation without modification, as the substitute provides complete functional and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM2003D be used as a direct replacement for the RK73G1HTTC2003D?

A: Yes. The RK73G1HTTCM2003D is the manufacturer-recommended substitute and provides complete electrical and mechanical equivalence. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package dimensions, and automotive certifications—are identical between the two parts.

Q: What is the significance of the "Not For New Designs" status on the RK73G1HTTC2003D?

A: This designation indicates that the manufacturer has transitioned the part to end-of-life status and recommends using the active substitute (RK73G1HTTCM2003D) for new design implementations. Existing designs may continue using the original part, but new projects should specify the active equivalent.

Q: Are there any differences in the 0201 package specifications between these parts?

A: No. Both components use the identical 0201 (0603 Metric) package with matching physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RK73G1HTTC2003D and RK73G1HTTCM2003D are AEC-Q200 qualified thick film chip resistors suitable for automotive applications. They maintain identical operating temperature ranges of -55°C ~ 155°C and temperature coefficient specifications of ±50ppm/°C.

Q: What is the difference between the packaging designations "Tape & Reel (TR)" and the substitute's "-" packaging notation?

A: The main part specifies "Tape & Reel (TR)" packaging format. The substitute part's packaging information is not explicitly detailed in the provided data. Confirm packaging format requirements with the supplier or component distributor when placing orders.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant and carry identical environmental compliance certifications including REACH Unaffected status and EAR99 ECCN classification.
