Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1007C100MPWST is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Package / Case: 1007 (2518 Metric)
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 105°C
• Self-resonant frequency: 30 MHz

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 165 mA
• DC resistance: Substitute may vary within application requirements
• RoHS and MSL compliance: Must maintain or exceed original specifications

The CBC2518T100M from Taiyo Yuden satisfies all mandatory matching parameters and exceeds the current rating requirement, making it a valid substitute for the obsolete L1007C100MPWST.

Parameter Comparison

Engineering Selection Recommendations

The CBC2518T100M is a direct functional substitute for the L1007C100MPWST. Both components share identical inductance values, package dimensions, core material composition, and operating temperature specifications. The CBC2518T100M provides superior current handling capability (680 mA versus 165 mA), making it suitable for applications where the original part is no longer available.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The higher DC resistance of the CBC2518T100M (468 mOhm maximum versus 250 mOhm) must be evaluated within the context of the specific application circuit to ensure thermal and performance requirements are satisfied.

The L1007C100MPWST is classified as Obsolete, while the CBC2518T100M is classified as Not For New Designs. For new production designs, consultation with component suppliers is necessary to identify currently active alternatives.

Frequently Asked Questions (FAQ)

Q: Can the CBC2518T100M replace the L1007C100MPWST in existing designs?

A: Yes. Both inductors share identical inductance values (10 µH), package dimensions (1007/2518 Metric), core material (ferrite), and operating temperature range (-40°C to 105°C). The CBC2518T100M provides higher current capacity (680 mA versus 165 mA), which is compatible with applications designed for the original part.

Q: What is the significance of the higher DC resistance in the CBC2518T100M?

A: The CBC2518T100M exhibits a maximum DC resistance of 468 mOhm compared to 250 mOhm in the L1007C100MPWST. This difference affects power dissipation and thermal characteristics. Circuit designers must verify that the increased resistance does not compromise performance in current-limiting, filtering, or impedance-matching applications.

Q: Are both parts suitable for high-frequency applications?

A: Both inductors have a self-resonant frequency of 30 MHz, indicating suitability for applications operating below this frequency threshold. Applications requiring operation near or above 30 MHz require detailed impedance analysis.

Q: Do both parts meet current environmental and compliance standards?

A: Yes. Both the L1007C100MPWST and CBC2518T100M are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting standard manufacturing and storage requirements.

Q: What packaging options are available for the CBC2518T100M?

A: The CBC2518T100M is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual and automated assembly processes.
