Frequently Asked Questions
What is the standard MOQ for this USB Type-C receptacle?
Our standard MOQ for factory-direct bulk orders is typically 1,000 pieces per tape-and-reel. However, we offer flexible prototype quantities (e.g., 500 pieces) to support your New Product Introduction (NPI) phase.
Does this connector support USB Power Delivery (PD) fast charging?
The connector is rated according to the engineering drawing for 100V AC RMS with a current rating of 3.0A on VBUS pins (A4, A9, B4, B9) and 1.25A on signal pins, reliably supporting standard Type-C power profiles up to 60W (20V/3A) alongside high-speed USB 3.2 Gen2 data transfer.
Are there custom plating options available for the contacts?
Absolutely. While standard gold flash is provided, our factory can apply heavier gold plating (e.g., 15µ" or 30µ") for environments that require enhanced corrosion resistance and extreme mating durability.
What compliance and certifications do your connectors meet?
Our USB-C receptacles are manufactured in ISO-certified facilities and fully comply with RoHS and REACH directives. They are also designed to meet the rigorous IPC/WHMA-A-620 criteria for electronic assemblies.
What is the typical lead time for bulk production?
Standard lead times range from 2 to 4 weeks depending on order volume and raw material availability. For urgent engineering needs, rapid prototyping and sampling can be completed in 3-5 days.
Overview and Application Notes
-
Overview: Engineered for reliable high-speed data transmission and durable hardware integration, the EU24F2B3N61358SR is a 24-pin USB Type-C top mount receptacle featuring a 1.60mm center height (CH=1.60mm, total body height 3.16mm). Molded from high-temperature UL94 V-0 thermoplastic, reinforced with an unplated stainless steel mid-plate, and equipped with a nickel-plated stainless steel shell and 24 gold-plated copper alloy contacts, it supports high-speed differential signal transfer and stable power delivery (3.0A on VBUS pins A4, A9, B4, B9; 1.25A on signal pins). Its dual-row SMT surface mount architecture with integrated PCB locating pegs (2-Ø0.52mm) provides excellent alignment, 360-degree EMI suppression, and reliable durability across an industrial operating temperature range of -40°C to +85°C.

Application Notes:
-
Top Mount Layout & Center Height: Features a top-mount configuration with a 1.60mm center height (CH=1.60mm, total connector height 3.16mm); verify PCB edge placement and enclosure cutout clearance against the recommended layout to avoid mechanical interference.
-
Dual-SMT Soldering & Locating Pegs: Utilizes a dual-row SMT contact layout (0.50mm pitch, 0.25mm pad width) paired with 2 molded locating pegs (2-Ø0.52mm holes) and 4 SMT shell grounding pads (0.98×0.70mm); optimize solder stencil apertures to prevent solder bridging.
-
Lead-Free Reflow Compatibility: Molded from high-temperature UL94 V-0 thermoplastic, fully compatible with standard RoHS lead-free IR and convection reflow soldering profiles (peak temperature up to 260°C).
-
Environmental & Dielectric Performance: Rated for an operating temperature range of -40°C to +85°C, relative humidity of 90%–95% (40±2°C), and 100V AC RMS (50Hz, 1 min) dielectric withstanding voltage.
