Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13R685C is determined by the following critical parameters:

• Inductance value of 6.8 mH with ±10% tolerance
• Through-hole mounting configuration
• Radial, vertical cylinder package geometry
• Unshielded construction
• Active product status and RoHS3 compliance

The substitute part RLB9012-682KL meets these core substitution criteria. While the substitute exhibits a higher current rating (200 mA versus 130 mA) and increased DC resistance (20.7 Ohm Max versus 14.6 Ohm Max), these parameters remain within acceptable variation for applications where the 13R685C operates below its maximum current specification. The substitute's wider operating temperature range (-55°C ~ 125°C) and ferrite drum core construction provide extended environmental capability.

Parameter Comparison

Engineering Selection Recommendations

Both the 13R685C and RLB9012-682KL maintain Active product status and satisfy RoHS3 compliance requirements. Selection between these components should be based on application-specific current requirements and thermal operating conditions. The 13R685C is suitable for applications operating within -40°C to 85°C with current demands not exceeding 130 mA. The RLB9012-682KL provides extended current capacity (200 mA) and broader temperature operation (-55°C to 125°C), making it applicable to more demanding thermal and electrical environments. Both components are through-hole mounted with identical inductance specifications and package geometry, ensuring mechanical compatibility in standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can RLB9012-682KL replace 13R685C in all applications?

A: Substitution is valid when the application current requirement does not exceed 130 mA, the operating temperature remains within -40°C to 85°C, and the increased DC resistance of 20.7 Ohm Max is acceptable for the circuit design. The RLB9012-682KL's higher current rating and wider temperature range do not create incompatibility in applications within these bounds.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The RLB9012-682KL exhibits 20.7 Ohm Max DC resistance compared to 14.6 Ohm Max in the 13R685C. This 7.2 Ohm difference increases power dissipation proportionally to the square of the current. Applications sensitive to resistive losses should evaluate this parameter against circuit performance requirements.

Q: Are the physical dimensions compatible?

A: Both components use radial, vertical cylinder packaging with similar form factors. The 13R685C measures 0.374" diameter by 0.531" height, while the RLB9012-682KL measures 0.354" diameter by 0.480" height. These dimensional variations are within typical PCB layout tolerances for through-hole radial components.

Q: Do both parts meet regulatory requirements?

A: Yes. Both the 13R685C and RLB9012-682KL are RoHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards for electronic component manufacturing and use.
