Substitute Part Grouping Explanation

Substitution of the Z0201C470CSMST is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Impedance value of 47 Ohms at 100 MHz
• Single signal line filter configuration
• DC resistance maximum of 1 Ohm
• Operating temperature range of -55°C to 125°C

Mechanical Equivalence Requirements:

• 0201 (0603 Metric) package form factor
• Surface mount mounting type
• Physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm)

Compliance Requirements:

• ROHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH Unaffected status

The substitute part BLM03BB750SZ1D from Murata Electronics meets all electrical and mechanical equivalence criteria. The substitute demonstrates a higher current rating (200mA versus 150mA), which represents an enhanced capability within the same package and electrical specification envelope. Both parts maintain identical impedance characteristics, DC resistance, operating temperature range, and package dimensions.
