Parameter Comparison

Engineering Selection Recommendations

The CB2518T102K from Taiyo Yuden is a qualified substitute for the L1007C102KPWST. Both components share identical inductance specifications, package dimensions, and operating temperature ranges. Both are ROHS3 compliant and carry MSL 1 moisture sensitivity ratings.

The CB2518T102K provides higher current rating capability (75 mA versus 15 mA) and includes specified saturation current (25 mA), offering enhanced performance margin in applications where the original 15 mA rating is utilized. The DC resistance difference (31.2 Ohm Max versus 24 Ohm) must be evaluated within specific circuit requirements.

The L1007C102KPWST carries Obsolete status, while the CB2518T102K carries Not For New Designs status. For ongoing production or repair applications, the CB2518T102K represents the available alternative from established component inventory.

Frequently Asked Questions (FAQ)

Q: Can CB2518T102K be used as a direct replacement for L1007C102KPWST?

A: Yes. Both components share identical inductance (1 mH ±10%), package dimensions (1007/2518 Metric), core type (ferrite unshielded drum core), operating temperature range (-40°C to 105°C), and self-resonant frequency (2.4 MHz). Physical and electrical compatibility is confirmed for surface mount applications.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (KEMET versus Taiyo Yuden), current rating (15 mA versus 75 mA), DC resistance (24 Ohm versus 31.2 Ohm Max), and packaging format (Cut Tape versus Tape & Reel). The CB2518T102K provides higher current capacity and includes specified saturation current data.

Q: Does the higher current rating of CB2518T102K affect compatibility?

A: No. Higher current rating indicates greater performance capability. In applications designed for 15 mA operation, the CB2518T102K operates within safe margins. The component will not be damaged by lower current draw.

Q: Are there packaging considerations when substituting?

A: The L1007C102KPWST is supplied in Cut Tape format, while CB2518T102K is supplied in Tape & Reel format. This affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Both formats contain identical component specifications.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both L1007C102KPWST and CB2518T102K are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and reliability standards.

Q: Why does the DC resistance differ between these parts?

A: DC resistance variation (24 Ohm versus 31.2 Ohm Max) reflects different manufacturing processes and wire gauge specifications between manufacturers. Circuit designs must account for this parameter when precise resistance values are critical to performance.
