Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73B1HTTC564G must satisfy the following criteria to ensure functional and mechanical compatibility:

Electrical Parameters (Critical):

• Resistance value: 560 kOhms
• Tolerance: ±2%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

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

Compliance & Material Parameters (Required):

• Composition: Thick Film
• Automotive rating: AEC-Q200
• RoHS status: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Parts meeting all these parameters are classified as direct substitutes. Variations in product status (active vs. not for new designs) do not affect electrical or mechanical compatibility but may influence long-term availability and supply chain decisions.

Parameter Comparison

Engineering Selection Recommendations

RK73B1HTTCM564G is a direct functional and mechanical equivalent to RK73B1HTTC564G. All critical electrical parameters, mechanical dimensions, and compliance certifications are identical between the two parts.

The primary distinction is product status: RK73B1HTTC564G is classified as "Not For New Designs," while RK73B1HTTCM564G maintains "Active" status. This indicates that RK73B1HTTCM564G represents the current production alternative within the RK73B series.

For applications currently using RK73B1HTTC564G, transition to RK73B1HTTCM564G is supported by:

• Identical electrical performance (560 kOhms ±2%, 0.05W, ±200ppm/°C)
• Identical mechanical compatibility (0201 package, same footprint and height)
• Maintained automotive qualification (AEC-Q200)
• Continued regulatory compliance (ROHS3, REACH Unaffected, MSL 1)
• Same manufacturer (KOA Speer Electronics, Inc.)

No design modifications, PCB layout changes, or thermal analysis revisions are required when substituting RK73B1HTTCM564G for RK73B1HTTC564G.

Frequently Asked Questions (FAQ)
