Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC241G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical resistance value of 240 Ohms
• Matching tolerance of ±2%
• Equivalent power rating of 0.05W (1/20W)
• Same package configuration: 0201 (0603 Metric)
• Identical thick film composition
• Matching temperature coefficient of ±200ppm/°C
• Identical operating temperature range of -55°C ~ 155°C
• AEC-Q200 automotive qualification
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

The primary distinction between the main part and its substitute is product status. The RK73B1HTTC241G is classified as Not For New Designs, while the substitute part RK73B1HTTCM241G maintains Active status, making it suitable for new design implementations and ongoing production.

Parameter Comparison
