Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 or RoHS standards. Selection among the substitute options should be based on the following criteria:

Amphenol ICC (FCI) Series (10137064-00011LF, 10152803-00011LF, 10163259-00011LF): These three Amphenol ICC parts are direct parametric equivalents with identical mechanical and electrical interface specifications. Part 10137064-00011LF offers the widest operating temperature range (-55°C ~ 85°C) and supports multiple current ratings (0.25A, 1.25A, 5A). Part 10152803-00011LF is rated for 5A at 5V with a narrower temperature range (-25°C ~ 85°C). Part 10163259-00011LF supports 5A current rating with unspecified temperature and voltage parameters. All three maintain 10000 mating cycles and are available in quantities exceeding 3800 units.

Hirose CX70M-24P2: This Hirose Electric connector extends the operating temperature range to -30°C ~ 105°C and is rated for 48VAC/DC at 5A. The CX70M series designation indicates a mid-mount configuration. This option is suitable for applications requiring extended thermal performance. Inventory availability is 2193 units.

Switchcraft RAHUC31AU1TR and RAHUC31AUTR: Both Switchcraft options are ROHS3 compliant with identical mechanical specifications. The RAHUC31AU1TR is rated for 3A at -30°C ~ 85°C, matching the original part's current rating. The RAHUC31AUTR supports 5A at 20VDC but specifies only 1000 mating cycles (compared to 10000 for the original). Operating temperature range is not specified for the RAHUC31AUTR. Inventory levels are 2661 and 2103 units respectively.

For applications requiring maximum thermal headroom, the Hirose CX70M-24P2 is recommended. For direct current-matched substitution, the Switchcraft RAHUC31AU1TR maintains the 3A rating. For applications requiring 5A capacity, any of the Amphenol ICC parts or the Switchcraft RAHUC31AUTR are suitable, with the Amphenol 10137064-00011LF offering the broadest temperature specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the AUSB1-DFN-HSR1 with any of the listed parts without PCB redesign?

A: Yes. All listed substitute parts share identical mechanical mounting specifications (surface mount, right angle, horizontal orientation) and electrical interface characteristics (USB-C, 24-position, receptacle, solder termination). No PCB layout modifications are required for direct substitution.

Q: What is the significance of the different current ratings among the substitute parts?

A: Current rating indicates the maximum continuous current the connector contacts can safely carry. The original AUSB1-DFN-HSR1 is rated for 3A. Substitute parts rated for 5A (such as 10152803-00011LF, 10163259-00011LF, CX70M-24P2, and RAHUC31AUTR) can handle higher current loads and are backward compatible with 3A applications. The Amphenol 10137064-00011LF offers multiple current ratings (0.25A, 1.25A, 5A), indicating flexible contact configurations.

Q: Are all substitute parts ROHS3 compliant?

A: Six of the seven substitute parts are explicitly ROHS3 compliant. The Hirose CX70M-24P2 is RoHS compliant (not specifically ROHS3). Both designations indicate compliance with Restriction of Hazardous Substances regulations. The Switchcraft parts do not specify flammability ratings, whereas the original and most substitutes are UL94 V-0 rated.

Q: What is the difference between the two Switchcraft options (RAHUC31AU1TR and RAHUC31AUTR)?

A: The RAHUC31AU1TR is rated for 3A current (matching the original part) with a specified operating temperature range of -30°C ~ 85°C. The RAHUC31AUTR is rated for 5A current at 20VDC but specifies only 1000 mating cycles (versus 10000 for the original and most substitutes). Operating temperature is not specified for the RAHUC31AUTR. Select RAHUC31AU1TR for current-matched performance; select RAHUC31AUTR only if higher current capacity is required and the reduced mating cycle specification is acceptable for your application.

Q: Which substitute offers the best thermal performance?

A: The Hirose CX70M-24P2 supports the widest operating temperature range (-30°C ~ 105°C), extending 20°C above the original part's maximum of 85°C. This makes it suitable for applications requiring extended high-temperature operation. The Amphenol 10137064-00011LF offers the lowest minimum temperature (-55°C), making it suitable for extreme cold environments.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are packaged in Tape & Reel (TR) format, matching the original AUSB1-DFN-HSR1 packaging specification. This ensures compatibility with automated assembly equipment and standard component handling procedures.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level (MSL) 1 indicates the lowest moisture sensitivity classification. "Unlimited" means the component can be stored indefinitely without special moisture control measures, provided it remains in its original sealed packaging. All listed parts share this specification, ensuring identical storage and handling requirements.

Q: Can I use the Amphenol 10137064-00011LF if my application only requires 3A?

A: Yes. The Amphenol 10137064-00011LF supports multiple current ratings including 0.25A, 1.25A, and 5A. A 3A application falls within the connector's rated capacity and is fully compatible. The part's wider operating temperature range (-55°C ~ 85°C) provides additional design margin compared to the original.

Q: What is the significance of mating cycles specification?

A: Mating cycles indicate the number of times the connector can be mated and unmated before performance degradation. The original AUSB1-DFN-HSR1 and most substitutes are rated for 10000 cycles. The Switchcraft RAHUC31AUTR is rated for only 1000 cycles, making it unsuitable for applications requiring frequent connection/disconnection cycles. For applications with high mating cycle requirements, avoid the RAHUC31AUTR.
