Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC565G is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 5.6 MOhms (exact match required)
• Tolerance: ±2% (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 format: 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 maximum: 0.010" / 0.26mm (exact match required)
• Termination count: 2 (exact match required)

Compliance & Quality Parameters:

• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)
• Composition: Thick Film (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. Parts meeting these criteria are functionally and mechanically interchangeable in applications designed for the RK73B1HTTC565G.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM565G is the designated manufacturer-recommended substitute for the RK73B1HTTC565G. Both components are manufactured by KOA Speer Electronics, Inc., and belong to the RK73B series. The substitute part maintains complete electrical and mechanical equivalence across all specified parameters.

The primary distinction between the two parts is product status: the main part RK73B1HTTC565G is classified as "Not For New Designs," while the substitute RK73B1HTTCM565G maintains Active status. This status difference reflects manufacturing lifecycle management and does not indicate any technical deficiency in the original part.

Both parts satisfy identical compliance requirements:

• AEC-Q200 automotive qualification
• ROHS3 compliance
• MSL 1 moisture sensitivity rating
• REACH unaffected status

Selection of RK73B1HTTCM565G is appropriate for applications requiring active product status, ongoing supply chain continuity, or new design implementations. The substitute part is directly interchangeable in all applications designed for the RK73B1HTTC565G without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM565G be used as a direct replacement for RK73B1HTTC565G?

A: Yes. The RK73B1HTTCM565G is electrically and mechanically identical to the RK73B1HTTC565G across all specified parameters. Both components share identical resistance, tolerance, power rating, package format, temperature characteristics, and automotive qualification. Direct substitution is permissible without circuit modification.

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

A: "Not For New Designs" indicates that the RK73B1HTTC565G has entered the mature phase of its product lifecycle. Manufacturers typically apply this designation to manage inventory and encourage migration to active alternatives. The RK73B1HTTCM565G, with Active status, represents the current production equivalent.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the RK73B1HTTC565G and RK73B1HTTCM565G are packaged in 0201 (0603 Metric) format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are identical.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both components are qualified to AEC-Q200 standards, confirming suitability for automotive applications. This qualification applies to the RK73B1HTTC565G and RK73B1HTTCM565G without distinction.

Q: What is the difference in packaging between the two parts?

A: The main part RK73B1HTTC565G is specified with Tape & Reel (TR) packaging. The substitute part RK73B1HTTCM565G does not specify packaging format in the provided data. Confirm packaging requirements with the supplier for procurement purposes.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 rating, and EAR99 ECCN classification. No compliance re-evaluation is required when substituting between these parts.

Q: What inventory levels are available for each part?

A: The RK73B1HTTC565G has 860 pieces in stock. The RK73B1HTTCM565G has 1138 pieces in stock. Inventory availability should be confirmed with the supplier at the time of procurement.
