Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55917-801LF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: USB-A and Power, Combo
• Number of Contacts: 8
• Gender: Receptacle
• Specifications: USB 2.0
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Features: Board Lock
• Operating Temperature Range: -55°C ~ 85°C
• Number of Ports: 1
• Voltage Rating: 12V
• Mating Cycles: 1500
• Shielding: Shielded
• Contact Finish: Gold, GXT™
• Shell/Shielding Material: Copper Alloy
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Current Rating: 55917-801LF rated at 5A; substitutes rated at 3A are acceptable for applications not requiring the full 5A capacity
• Insulation Color: Teal (original) vs. Black (substitute) — functional equivalence maintained
• Packaging: Bulk or Tray formats acceptable for different procurement workflows
• Product Status: Active alternatives preferred over obsolete original

The substitute parts 55917-501LF and 55917-500LF meet all mandatory matching criteria and differ only in allowable variation parameters.

Parameter Comparison

Engineering Selection Recommendations

55917-501LF (MFR Recommended Substitute): This part is the manufacturer-recommended alternative, maintaining active product status with RoHS and REACH compliance. It is functionally equivalent across all critical parameters with the exception of current rating (3A vs. 5A). Selection of this part is appropriate for applications where the 3A current capacity satisfies system requirements. Bulk packaging supports high-volume production workflows.

55917-500LF (Parametric Equivalent Substitute): This part provides parametric equivalence with identical electrical and mechanical specifications to 55917-501LF, differentiated by insulation color (Black vs. Teal) and packaging format (Tray vs. Bulk). Active product status with RoHS and REACH compliance is maintained. Selection is appropriate where tray packaging aligns with procurement or assembly processes and insulation color variation is acceptable for the application.

Current Rating Consideration: Both substitute parts are rated at 3A, compared to the original 5A rating. Applications requiring sustained current draw exceeding 3A must be evaluated against actual system power requirements. For applications operating within 3A limits, both substitutes provide full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can 55917-501LF and 55917-500LF be used interchangeably with 55917-801LF?

A: Both parts are functionally equivalent substitutes for the 55917-801LF across all critical electrical and mechanical parameters. The primary consideration is current rating: the original part is rated at 5A, while both substitutes are rated at 3A. Selection depends on whether your application requires the full 5A capacity. If your system operates within 3A limits, either substitute provides complete functional compatibility.

Q: What is the difference between 55917-501LF and 55917-500LF?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The differences are: (1) Insulation color — 55917-501LF is Teal, 55917-500LF is Black; (2) Packaging — 55917-501LF is supplied in Bulk format, 55917-500LF in Tray format. Selection between these two depends on packaging requirements and whether insulation color variation is acceptable for your application.

Q: Why is the original 55917-801LF listed as obsolete?

A: The 55917-801LF is obsolete, meaning it is no longer in active production. The manufacturer recommends transitioning to 55917-501LF for new designs and production continuity. Both active alternatives maintain the same connector functionality and form factor.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both 55917-501LF and 55917-500LF are RoHS Compliant and REACH Affected, meeting current environmental and regulatory requirements. The original 55917-801LF compliance status was not specified in available documentation.

Q: What is the current rating difference, and does it affect my design?

A: The original 55917-801LF is rated at 5A, while both substitutes (55917-501LF and 55917-500LF) are rated at 3A. This difference is significant only if your application requires sustained current draw exceeding 3A. For applications operating at or below 3A, the substitutes provide equivalent performance. Review your system power requirements to determine if the 3A rating is sufficient.

Q: Can I mix packaging formats in production?

A: Yes. 55917-501LF (Bulk packaging) and 55917-500LF (Tray packaging) are electrically and mechanically identical. Packaging format selection depends on your procurement, storage, and assembly workflow requirements. Both formats contain the same component.
