Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC153G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

• Identical resistance value: 15 kOhms
• Identical tolerance: ±2%
• Identical power rating: 0.05W (1/20W)
• Identical package format: 0201 (0603 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: 1 (Unlimited)

Only parts meeting all these parameters are classified as direct equivalents. The primary distinction between the main part and its substitute relates to product lifecycle status and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM153G is the direct equivalent substitute for the RK73B1HTTC153G. Both parts are manufactured by KOA Speer Electronics, Inc. within the RK73B series and maintain identical electrical and mechanical specifications across all parameters.
