Hello, I received a message that the HMC540LP3E will be end of life, and the last time buy should be placed before 21 August 2015. The HMC540SLP3E should be the replacement, but information should only array in October. This is too late to assess the component for the all time buy.

Since only the letters change LP3E/SLP3E, can I assume that the differences will be minor?

Is any advance datasheet available?

Will the cost be approximately be equal to the HMC540LP3E, or lower?

(I need about 3500 of these devices)
