Amphenol ICC 72309-8024RLF USB 2.0 Stacked Receptacle Connector

Part Overview

The Amphenol ICC 72309-8024RLF is an active USB-A stacked receptacle connector designed for through-hole, right-angle mounting applications. This 8-position connector supports USB 2.0 specifications with a current rating of 1.5A per contact and operates across the industrial temperature range of -55°C to 85°C. The connector features board lock functionality, shielded construction, and gold-plated GXT™ contact finish for reliable signal integrity and durability across 1500 mating cycles. Alternative part numbers are necessary when specific packaging requirements, inventory constraints, or insulation color specifications differ from the primary part designation.

Key Parameters

Substitute Part Grouping Explanation

The 72309-3045RPLF qualifies as a parametric equivalent to the 72309-8024RLF based on the following critical substitution criteria:

Matching Parameters:

• Connector Type: USB-A (USB TYPE-A), Stacked
• Number of Contacts: 8
• Gender: Receptacle
• USB Specifications: USB 2.0
• Mounting Type: Through Hole, Right Angle
• Number of Ports: 2
• Current Rating: 1.5A per Contact
• Operating Temperature Range: -55°C to 85°C
• Mating Cycles: 1500
• Shielding: Shielded
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters:

• Packaging: 72309-8024RLF supplied in Tape & Reel (TR); 72309-3045RPLF supplied in Cut Tape (CT)
• Insulation Color: 72309-8024RLF features white insulation; 72309-3045RPLF features black insulation
• Contact Finish: 72309-8024RLF specifies Gold, GXT™; 72309-3045RPLF specifies Gold

These differences do not affect electrical or mechanical compatibility. Both parts maintain identical functional performance within the same series (72309) and support equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 72309-8024RLF and 72309-3045RPLF are active products from Amphenol ICC with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

72309-8024RLF (Tape & Reel Packaging): Select this part number when high-volume automated assembly processes require tape and reel packaging. The GXT™ contact finish provides enhanced durability for applications requiring extended mating cycle performance.

72309-3045RPLF (Cut Tape Packaging): Select this part number when lower-volume requirements, manual assembly processes, or inventory management favor cut tape packaging. This variant maintains full electrical and mechanical compatibility while offering alternative packaging logistics.

Both parts comply with RoHS regulations, maintain MSL 1 (unlimited moisture sensitivity), and support identical operating parameters across the -55°C to 85°C temperature range. The choice between white and black insulation color is a cosmetic consideration that does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 72309-8024RLF and 72309-3045RPLF electrically interchangeable?

A: Yes. Both connectors support identical USB 2.0 specifications, current ratings (1.5A per contact), operating temperatures (-55°C to 85°C), and mating cycle ratings (1500 cycles). Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly operations. Both packaging formats contain identical components.

Q: Does the insulation color difference affect connector performance?

A: No. Insulation color (white vs. black) is a cosmetic specification that does not impact electrical performance, mechanical compatibility, or signal integrity. Selection should be based on assembly process requirements or visual identification preferences.

Q: Are both parts RoHS compliant?

A: Yes. Both the 72309-8024RLF and 72309-3045RPLF are RoHS compliant and suitable for applications requiring restricted substance compliance.

Q: What is the difference between Gold and Gold GXT™ contact finishes?

A: Both finishes provide reliable electrical contact and corrosion resistance. The GXT™ designation indicates an enhanced gold plating process that may provide extended durability in high-cycle applications. Both finishes support the rated 1500 mating cycles.

Q: Can I use these connectors in industrial temperature applications?

A: Yes. Both connectors operate across the -55°C to 85°C temperature range, supporting industrial and extended temperature applications.
