Need Part EOL status(Active/Obsolete/discontinued/NRFND)

Hi, Can you please provide Part status for PN's PL-USB-BLASTER-RCN, PL-USB-BLASTER-RB . If Obsolete can you provide drop in replacement? Since 'PL-USB-BLASTER-RCN' is drop in replacement for 'PL-USB-BLASTER-RB', so is PL-USB-BLASTER-RB no longer manufactured?
