Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23S4R7C is permissible when the alternative component maintains the following critical parameters: inductance value of 4.7 µH, shielded construction, surface mount configuration, and RoHS3 compliance. The substitute part SRR6603-4R7ML meets these core requirements. Acceptable variations include current rating (1.4 A vs. 1.6 A), DC resistance (60mOhm vs. 44mOhm), and operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), provided the application circuit design accommodates these differences. Physical dimensions and core material differences (drum core ferrite vs. standard wirewound) are acceptable when PCB layout and thermal management allow.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 23S4R7C and SRR6603-4R7ML is determined by application current requirements and thermal constraints. The 23S4R7C supports higher continuous current (1.6 A) with lower DC resistance (44mOhm), making it suitable for applications requiring maximum current capacity. The SRR6603-4R7ML provides extended operating temperature range (-55°C ~ 125°C) and lower profile height (3.00mm vs. 3.20mm), advantageous for temperature-critical or space-constrained designs. Both components maintain identical inductance value, shielded construction, surface mount compatibility, and full RoHS3 compliance. Physical dimension differences require PCB layout verification prior to substitution.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-4R7ML replace 23S4R7C in all applications? A: Substitution is valid when circuit design accommodates the lower current rating (1.4 A vs. 1.6 A) and higher DC resistance (60mOhm vs. 44mOhm). Applications operating at or near 1.6 A continuous current require verification that the substitute part meets thermal and performance requirements.

Q: What are the physical dimension differences? A: The 23S4R7C measures 6.20mm L x 5.60mm W x 3.20mm H. The SRR6603-4R7ML measures 6.60mm L x 4.40mm W x 3.00mm H. PCB layout must accommodate these variations in footprint and height.

Q: Are both parts RoHS3 compliant? A: Yes. Both the 23S4R7C and SRR6603-4R7ML are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the inductance tolerance of the substitute part? A: The SRR6603-4R7ML has an inductance tolerance of ±20%.

Q: Do both parts have identical shielding? A: Both components are shielded inductors. The 23S4R7C uses standard wirewound construction, while the SRR6603-4R7ML uses drum core ferrite wirewound construction. Both provide electromagnetic shielding suitable for surface mount applications.
