Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SUSBX are identified based on strict alignment with the following critical parameters:

Core Compatibility Criteria:

• Connector Type: USB-A (USB TYPE-A) receptacle
• Number of Contacts: 4 positions
• Gender: Receptacle
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Features: Board Lock
• Mating Cycles: 1500 cycles minimum
• Material Flammability Rating: UL94 V-0

Substitute Parts Identified:

1. 87520-0010ALF (Amphenol ICC / FCI) – Direct manufacturer substitute with active product status, USB 2.0 specification, and full parameter alignment including shielded construction and gold contact finish.

2. USB-A-S-F-B-TH (Samtec Inc.) – Similar manufacturer substitute with active product status, USB 2.0 specification, shielded construction, and equivalent mechanical and electrical characteristics.

Both substitute parts maintain the same connector type, contact count, mounting configuration, and board lock feature as the SUSBX, ensuring direct functional equivalence in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

87520-0010ALF (Amphenol ICC / FCI): This part is recommended as the primary direct substitute for the SUSBX. It maintains active product status with full RoHS compliance and carries USB 2.0 specification. The part is available in high inventory (7386 pcs) and provides equivalent mechanical and electrical performance. The unshielded construction differs from the SUSBX; applications requiring EMI shielding should evaluate this difference against specific design requirements.

USB-A-S-F-B-TH (Samtec Inc.): This part serves as an alternative substitute with active product status and ROHS3 compliance matching the SUSBX. It retains shielded construction, making it suitable for applications with EMI sensitivity. The operating temperature range (-50°C ~ 85°C) and 30VAC voltage rating are provided specifications. Inventory availability is 2326 pcs.

Both substitute parts satisfy the core mechanical and electrical requirements of the SUSBX and are suitable for direct replacement in through-hole PCB designs with board lock retention.

Frequently Asked Questions (FAQ)

Q: Can the 87520-0010ALF replace the SUSBX directly? A: Yes. Both connectors share identical connector type, contact count, mounting configuration, and board lock features. The primary difference is shielding: the 87520-0010ALF is unshielded while the SUSBX is shielded. Evaluate EMI requirements for your application.

Q: What is the difference between the two substitute parts? A: Both 87520-0010ALF and USB-A-S-F-B-TH are functionally equivalent to the SUSBX. The 87520-0010ALF is unshielded; the USB-A-S-F-B-TH is shielded. Select based on EMI shielding requirements and packaging availability (Cut Tape vs. Tray).

Q: Are the substitute parts RoHS compliant? A: Yes. The 87520-0010ALF is RoHS Compliant. The USB-A-S-F-B-TH is ROHS3 Compliant. Both meet regulatory requirements for lead-free manufacturing.

Q: What is the mating cycle rating for these connectors? A: All three connectors (SUSBX, 87520-0010ALF, and USB-A-S-F-B-TH) are rated for 1500 mating cycles, ensuring equivalent mechanical durability.

Q: Can I use these connectors in high-temperature applications? A: The 87520-0010ALF operates from -55°C to 85°C. The USB-A-S-F-B-TH operates from -50°C to 85°C. Verify your application's temperature requirements against these ranges.

Q: What packaging options are available? A: The SUSBX is supplied in Bulk packaging. The 87520-0010ALF is available in Cut Tape (CT). The USB-A-S-F-B-TH is available in Tray. Select based on production volume and assembly requirements.
