Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73H1HTTC5232D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 52.3 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Substitute parts must maintain identical electrical performance, thermal characteristics, and environmental ratings. Physical dimensions, termination count, and regulatory compliance certifications must remain unchanged. Substitutes are grouped based on active product status and manufacturing availability while preserving all functional and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

The RK73H1HTTCM5232D is the direct substitute for the RK73H1HTTC5232D. Both components are manufactured by KOA Speer Electronics, Inc. within the RK73H series and maintain identical electrical, thermal, and mechanical specifications.

The primary distinction is product lifecycle status: the RK73H1HTTC5232D is designated "Not For New Designs," while the RK73H1HTTCM5232D carries "Active" status. This indicates the substitute part receives ongoing manufacturing support, improved supply chain availability, and continued compliance verification.

Both parts satisfy AEC-Q200 automotive qualification requirements, ROHS3 compliance, and REACH regulatory status. The substitute part is suitable for direct replacement in existing designs and is the preferred selection for new applications requiring a 52.3 kOhms ±0.5% 0.05W thick film resistor in 0201 package format with automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM5232D be used as a direct replacement for the RK73H1HTTC5232D?

A: Yes. The RK73H1HTTCM5232D is electrically and mechanically identical to the RK73H1HTTC5232D. All critical parameters including resistance value, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range are equivalent. Both components meet AEC-Q200 automotive standards and ROHS3 compliance requirements.

Q: Why is the RK73H1HTTC5232D marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's active product portfolio. The RK73H1HTTCM5232D represents the current active equivalent. For new designs, the substitute part is recommended to ensure long-term supply availability and continued manufacturing support.

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

A: No. Both components use the identical 0201 (0603 Metric) package format with 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 remain unchanged.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the RK73H1HTTC5232D and RK73H1HTTCM5232D are AEC-Q200 qualified, indicating compliance with automotive-grade reliability and environmental stress testing requirements. Both are suitable for automotive applications requiring high-reliability thick film resistors.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related storage or handling restrictions. Standard component storage practices apply without special desiccant or humidity control requirements.
