Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC565J is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 5.6 MOhms
• Tolerance: ±5%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package format: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated maximum: 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Quality Parameters:

• Automotive qualification: AEC-Q200
• Composition: Thick Film

Substitute parts must match all electrical specifications, maintain identical package geometry, and retain automotive-grade certification. Product status transition from "Not For New Designs" to "Active" is permissible for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM565J serves as the direct equivalent substitute for the RK73B1HTTC565J. Both components are manufactured by KOA Speer Electronics within the RK73B series and maintain identical electrical, mechanical, and thermal specifications. The primary distinction is product lifecycle status: the original part is designated "Not For New Designs," while the substitute maintains "Active" status.

For applications requiring the 5.6 MOhms ±5% 0.05W 0201 package resistor with AEC-Q200 automotive qualification, the RK73B1HTTCM565J is the appropriate selection. Both parts satisfy ROHS3 compliance requirements and maintain MSL 1 moisture sensitivity classification, indicating no special handling requirements during storage or assembly.

The substitute part demonstrates superior inventory availability (1125 pieces versus 737 pieces), supporting production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM565J be used as a direct replacement for RK73B1HTTC565J in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (5.6 MOhms), tolerance (±5%), power rating (0.05W), package format (0201), temperature coefficient (±200ppm/°C), and operating range (-55°C ~ 155°C). AEC-Q200 automotive qualification is maintained on both components.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: The original part RK73B1HTTC565J is in end-of-life phase and is not recommended for new design implementations. The substitute RK73B1HTTCM565J maintains active production status, ensuring long-term availability and supply chain stability for both new and existing applications.

Q: Are there any package or footprint differences between these parts?

A: No. Both components utilize the 0201 (0603 Metric) package with identical physical dimensions: 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 remain unchanged.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both RK73B1HTTC565J and RK73B1HTTCM565J carry AEC-Q200 certification, qualifying them for automotive applications requiring reliability and performance standards specific to the automotive industry.

Q: What is the moisture sensitivity classification for these resistors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity concerns. Standard storage conditions without specialized dry-pack requirements are acceptable.
