RK73G1HTTC3602D Equivalent & Substitute Parts

Part Overview

The RK73G1HTTC3602D is a 36 kOhms ±0.5% chip resistor manufactured by KOA Speer Electronics, Inc., rated at 0.05W (1/20W) in a 0201 (0603 Metric) package. This thick film resistor is qualified to the automotive AEC-Q200 standard and operates across the temperature range of -55°C to 155°C. The part is currently classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and transition to active product alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC3602D is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 36 kOhms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• 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 & Certification:

• Automotive AEC-Q200 qualification
• RoHS3 compliance
• Moisture Sensitivity Level 1

A substitute part must match all electrical specifications, maintain the identical 0201 package footprint, and retain AEC-Q200 automotive qualification. Composition (thick film) and manufacturer series (RK73G) are consistent across qualified alternatives.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3602D is the direct substitute for the RK73G1HTTC3602D. Both parts are manufactured by KOA Speer Electronics, Inc., and are members of the RK73G thick film resistor series. The substitute part is electrically and mechanically identical, with all critical parameters matching exactly: 36 kOhms resistance, ±0.5% tolerance, 0.05W power rating, 0201 package, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range.

The primary distinction is product status: the main part is classified as Not For New Designs, while the substitute is Active. This indicates that RK73G1HTTCM3602D represents the current production alternative and is the recommended selection for new designs and ongoing production requirements. Both parts maintain full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility in automotive and high-reliability applications.
