C102316832E1

Product Overview

The C102316832E1 is one of the thinnest push-push microSD card sockets on the market today. With a total height of just 1.25 mm, a reliable self-eject mechanism, and a built-in NC detection switch, it delivers full functionality in the smallest possible footprint. Designed as a direct replacement for the JAE ST11S008V4HR2000, it allows engineers to swap components without any PCB or tooling changes. The metal shield shell provides EMI protection while reinforced hold-down tabs ensure solder joint reliability under vibration and thermal stress. Manufactured by VITALCONN in Shenzhen, China, it offers short lead times of 2-4 weeks with competitive pricing.

FAQ

Q1: Is the C102316832E1 compatible with standard Micro SD cards?

A: Yes. The C102316832E1 accepts standard Micro SD (TF) cards conforming to the SD Association specification, including SDHC and SDXC cards up to the maximum supported capacity of the host device.

Q2: Does it support hot-swapping?

A: The mechanical design supports card insertion and removal during powered operation (hot-swapping). However, please follow your device manufacturer’s hot-swap guidelines to ensure data integrity and prevent host controller damage.

Q3: What is the recommended reflow profile for SMT mounting?

A: The C102316832E1 is compatible with standard Pb-free IR reflow soldering (JEDEC J-STD-020). For specific profile parameters, please refer to the full datasheet or contact VITALCONN technical support at support@vitalconn.com.

Q4: How does the NC card detection switch work?

A: The NC (Normally Closed) detect switch is mechanically actuated by card insertion. When no card is present, the switch is closed (conducting). When a card is fully inserted, the switch opens, signaling the host controller that a card is present. This eliminates the need for a separate external detect circuit.

Q5: What is the mechanical lifespan?

A: The push-push ejection mechanism is rated for a minimum of 5,000 insertion/removal cycles under standard test conditions.

Q6: Is there a tray/tape packaging option for SMT assembly?

A: Yes. The C102316832E1 is packaged in standard 7-inch or 13-inch reels with EIA-481 compliant taping. SPQ: 2,000 pcs/reel.

Q7: What is the typical lead time?

A: Standard lead time is 4–6 weeks for production quantities. For large orders or custom configurations, please contact VITALCONN sales at sales@vitalconn.com.
