Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1007R100MPWRT is determined by strict equivalence across 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
• Self resonant frequency: 30 MHz
• Operating temperature range: -40°C to 105°C
• Inductance test frequency: 2.52 MHz

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 180 mA
• DC resistance: Substitute specifications are application-dependent
• Product status: Obsolete or Not For New Designs status does not preclude substitution

The CBC2518T100M from Taiyo Yuden meets all mandatory matching parameters and exceeds the current rating requirement at 680 mA, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CBC2518T100M from Taiyo Yuden is a direct functional substitute for the obsolete L1007R100MPWRT. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Taiyo Yuden part carries a Not For New Designs status, indicating limited long-term availability; however, it provides immediate substitution capability for existing designs requiring the L1007R100MPWRT.

The CBC2518T100M demonstrates superior current handling capability at 680 mA versus the original 180 mA rating, providing design margin for applications operating at or near the original part's current limits. The increased DC resistance of 468 mOhm maximum compared to 190 mOhm in the original part must be evaluated within the specific circuit application to ensure thermal and performance requirements remain satisfied.

Both parts share identical mechanical dimensions, package configuration, and electrical characteristics for inductance value, tolerance, and frequency response, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the CBC2518T100M be used as a direct replacement for the L1007R100MPWRT in existing designs?

A: Yes. Both components share identical inductance values, tolerances, package dimensions, and operating temperature ranges. The CBC2518T100M provides equivalent electrical performance with enhanced current rating capability.

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

A: The CBC2518T100M exhibits a maximum DC resistance of 468 mOhm compared to 190 mOhm in the L1007R100MPWRT. This difference affects power dissipation and thermal performance. Circuit designers must evaluate whether the increased resistance is acceptable for their specific application requirements.

Q: Are both parts suitable for new designs?

A: The L1007R100MPWRT carries Obsolete status and is not suitable for new designs. The CBC2518T100M carries Not For New Designs status, indicating limited future availability. For new designs, consultation with component suppliers for current production alternatives is recommended.

Q: Do the parts require different PCB footprints or assembly processes?

A: No. Both components use the identical 1007 (2518 Metric) surface mount package with matching dimensions of 0.098" L x 0.071" W and 0.079" maximum seated height. No PCB layout or assembly process modifications are required.

Q: Are there compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No compliance or certification differences exist between the two components.

Q: What is the saturation current specification for the L1007R100MPWRT?

A: The saturation current (Isat) specification is not provided for the L1007R100MPWRT. The CBC2518T100M specifies an Isat of 480 mA, which exceeds the original part's 180 mA current rating.
