Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 57496-101LF is determined by strict alignment across the following critical parameters:

• Connector Type: USB-A and Power combo configuration
• Gender: Plug orientation
• Specifications: USB 2.0 compliance
• Mounting Type: Free Hanging (In-Line)
• Termination: Solder attachment
• Operating Temperature Range: -55°C ~ 85°C
• Current Rating: 1.5A and 3A support
• Mating Cycles: 1500 minimum
• Shielding: Shielded construction
• Material Flammability: UL94 V-0

The substitute parts 74233-3029LF and 74233-302LF meet all critical electrical and mechanical parameters. Both are active products from Amphenol ICC (FCI) with identical USB 2.0 specifications, operating temperature ranges, current ratings, mating cycles, and shielding characteristics. The primary difference is contact count (8 positions versus 9 positions in the main part) and shell material composition (steel/stainless versus copper alloy). Both substitutes carry RoHS compliance and REACH compliance status, providing regulatory advantages over the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both 74233-3029LF and 74233-302LF are suitable substitutes for the obsolete 57496-101LF based on electrical and mechanical parameter alignment. The primary selection criterion is product status: both substitutes are active products with current manufacturing support, whereas the main part is obsolete.

The 74233-3029LF and 74233-302LF both carry RoHS compliance certification, providing regulatory advantage for applications subject to RoHS directives. The 74233-3029LF additionally carries REACH compliance status. Both substitutes feature enhanced contact finish (Gold with GXT™) compared to the main part's standard gold finish, and employ stainless steel shielding material instead of copper alloy.

The contact count difference (8 versus 9 positions) must be evaluated against specific application requirements. If the design utilizes all 9 positions of the main part, pin mapping and functional compatibility must be assessed before substitution.

Frequently Asked Questions (FAQ)

Q: Can 74233-3029LF and 74233-302LF be used interchangeably with 57496-101LF?

A: Both substitutes meet the critical electrical and mechanical parameters of the main part, including USB 2.0 specifications, operating temperature range, current ratings, and shielding requirements. However, the contact count difference (8 versus 9 positions) requires design verification to confirm pin mapping compatibility.

Q: What is the significance of the contact count difference?

A: The main part 57496-101LF has 9 contacts, while both substitutes have 8 contacts. This difference must be evaluated against the specific pin assignments in your application. If all 9 positions are utilized in the original design, functional compatibility must be confirmed before substitution.

Q: Why are the substitute parts listed as active while the main part is obsolete?

A: The 57496-101LF has reached end-of-life status and is no longer manufactured. The substitute parts 74233-3029LF and 74233-302LF are current production items from the same manufacturer, ensuring ongoing availability and manufacturing support.

Q: What are the compliance advantages of the substitute parts?

A: Both substitutes carry RoHS compliance certification. The 74233-3029LF additionally carries REACH compliance status. These certifications provide regulatory compliance for applications subject to environmental and hazardous substance directives.

Q: How do the shell materials differ between the main part and substitutes?

A: The main part uses copper alloy shielding material, while both substitutes employ stainless steel. Both materials maintain UL94 V-0 flammability rating and provide equivalent shielding performance for USB 2.0 applications.

Q: Are the contact finishes equivalent?

A: The main part features standard gold contact finish. Both substitutes feature gold with GXT™ enhancement, providing improved durability and contact reliability characteristics.
