If your device is genuinely a LIFEPAK CR Plus, yes, this is the correct pediatric electrode regardless of which specific configuration or software revision your CR Plus unit is running; no CR Plus sub-variant compatibility issue was identified in researching this product.
The distinction that matters is not within the CR Plus line, it is between the CR Plus and its successor, the LIFEPAK CR2. The CR Plus has been discontinued and replaced by the CR2, which uses a different pediatric part number entirely. If you are unsure whether your device is a CR Plus or a CR2, check the model name printed on the front of the unit, or call Total AEDs at (855) 286-6384 with your serial number for confirmation.
