The TPME687M006R0018 is a molded tantalum capacitor from KYOCERA AVX's TPM series, offering 680 µF at 6.3 V with a very low 18 mΩ ESR. That ESR figure is the key selection parameter here — it keeps ripple heating under control when the cap is used as a bulk decoupling element on a 3.3 V or 1.8 V rail, where the ripple current can reach several amps without exceeding the part's self-heating limit.
The order codes TPME687M006R0018 and TPME687M006R0015 both belong to the same TPM series and share the same capacitance (680 µF), voltage (6.3 V), and case size (E code / 2917). The difference is in the ESR rating — the '0018 suffix indicates 18 mΩ, while the '0015 variant carries a different ESR value. They are not drop-in equivalents unless the circuit's ripple current and ESR tolerance match the alternate part's spec.
The TPM series is listed as a General Purpose molded tantalum capacitor. KYOCERA AVX typically ships these as RoHS-compliant, but the evidence does not carry an explicit RoHS status for this order code. Confirm the compliance marking on the reel label or request a RoHS certificate of compliance with the RFQ.
