Overview
The EDAC Inc. model 306-035-421-158 is a card edge connector from the 306 series, designed for panel mount installation with through-hole termination. It features a dual female configuration with 35 positions arranged in a single centerline row. The contact spacing is 0.156 inches (3.96 mm), and it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The insulator body is green thermoplastic polyester, and contacts are copper alloy with gold plating. Operating temperature ranges from -40°C to 105°C.
Feature Summary
- Single centerline row design for compact vertical mounting
- Low profile insulator body construction
- Gold-plated copper alloy contacts for reliable signal transmission
- Panel mount installation with flange support
Applications
- Medical interconnect solutions requiring durable connections
- Agricultural technology equipment operating in harsh environments
- Industrial control systems needing reliable board-to-panel interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to ensure correct termination style and flange configuration. Confirm that the target PCB thickness matches the 0.062-inch specification. Check RoHS compliance status if required by project regulations. Ensure the supplier provides official EDAC documentation for quality assurance.
Selection Notes
Choose this component when a single-row, low-profile card edge connector is needed for panel mounting. The 0.156-inch pitch suits applications where space is limited but robust connection is required. Verify compatibility with the mating card's edge thickness and guide rail requirements before finalizing the selection.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various configurations including different contact counts, termination styles, and mounting options. The 306 series is widely used in industrial and medical applications due to its reliability and durability in demanding environments.
Replacement Considerations
Direct substitutes within the same series include parts with identical pitch and position count but different termination or flange options. Cross-series replacements require matching pitch, row configuration, and mounting style. Always verify mechanical dimensions and electrical specifications before substituting.
