Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC562G is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 5.6 kOhms (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 type: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Certification:

• Automotive rating: AEC-Q200 (exact match required)
• RoHS status: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The substitute part RK73B1HTTCM562G meets all electrical, mechanical, and compliance requirements for direct substitution. The primary distinction is product status: the original part is "Not For New Designs" while the substitute is "Active," making it the recommended selection for ongoing applications.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM562G is the direct equivalent substitute for the RK73B1HTTC562G. Both parts are manufactured by KOA Speer Electronics within the RK73B series and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The substitute part carries "Active" product status, indicating ongoing manufacturer support and availability. The original part's "Not For New Designs" classification reflects its supersession in the product line. For applications requiring the 5.6 kOhms ±2% 0.05W 0201 package resistor with AEC-Q200 automotive qualification, the RK73B1HTTCM562G provides full functional and physical compatibility.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical thermal and electrical performance characteristics across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM562G be used as a direct replacement for RK73B1HTTC562G?

A: Yes. The substitute part meets all electrical, mechanical, and compliance specifications. Both components deliver 5.6 kOhms ±2% resistance at 0.05W power rating in 0201 package with AEC-Q200 automotive qualification.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The primary difference is product lifecycle status: RK73B1HTTC562G is classified "Not For New Designs," while RK73B1HTTCM562G is "Active." The substitute represents the current production equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). They are fully interchangeable in PCB layouts designed for 0201 package resistors.

Q: Do both parts meet automotive standards?

A: Yes. Both RK73B1HTTC562G and RK73B1HTTCM562G carry AEC-Q200 qualification and are suitable for automotive applications within the specified -55°C to 155°C operating temperature range.

Q: Is there a packaging difference?

A: The original part is specified as Tape & Reel (TR) packaging. The substitute packaging is not specified in available data. Confirm packaging requirements with the supplier for your specific procurement needs.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.
