TE Connectivity 787745-3 USB-A Stacked Receptacle Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 787745-3 is a USB-A Type-A stacked receptacle connector with 8 positions, designed for through-hole, right-angle mounting applications. This connector features a board lock mechanism, solder termination, and operates across a temperature range of -55°C to 85°C with a current rating of 1A per contact. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 787745-3 are identified based on strict alignment with the following critical parameters: connector type (USB-A stacked receptacle), number of contacts (8 positions), gender (receptacle), mounting configuration (through-hole, right-angle, horizontal), termination method (solder), number of ports (2), current rating capability (minimum 1A per contact), voltage rating (minimum 30VAC), operating temperature range (minimum -55°C to 85°C), shielding (shielded), contact finish (gold-based), flammability rating (UL94 V-0), and mating cycle durability (1500 cycles).

Substitutes are grouped into two categories:

Direct Manufacturer Equivalent: Parts from the same manufacturer (TE Connectivity) that maintain identical or superior electrical and mechanical specifications while offering improved product status or compliance certifications.

Similar Manufacturer Alternative: Parts from alternative manufacturers (Molex) that satisfy all critical functional and mechanical parameters, enabling cross-manufacturer substitution where design constraints permit.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5787745-3 (Direct Manufacturer Equivalent): This part is the primary substitute for the obsolete 787745-3. It maintains identical electrical and mechanical specifications, including the full operating temperature range (-55°C to 85°C), current rating (1A per contact), voltage rating (30VAC), and mating cycle durability (1500 cycles). The 5787745-3 carries active product status and achieves ROHS3 compliance, eliminating regulatory constraints associated with the non-compliant original part. This substitute is suitable for direct replacement in all applications where the 787745-3 was originally specified.

Molex 0672984090 (Similar Manufacturer Alternative): This part provides cross-manufacturer substitution capability with identical mechanical form factor and mounting configuration. The Molex connector exceeds the original current rating specification (1.5A versus 1A per contact) and maintains UL94 V-0 flammability certification. However, the operating temperature range (0°C to 50°C) is narrower than the original specification (-55°C to 85°C), and mating cycle data is not provided. This alternative is suitable for applications operating within the 0°C to 50°C temperature envelope where extended low-temperature or high-temperature performance is not required. The part carries ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5787745-3 be used as a direct replacement for the 787745-3?

A: Yes. The 5787745-3 maintains identical specifications for connector type, contact count, mounting configuration, current rating, voltage rating, operating temperature range, and mating cycle durability. The primary advantage is active product status and ROHS3 compliance, making it the recommended substitute for ongoing production and design updates.

Q: What are the limitations of the Molex 0672984090 as a substitute?

A: The Molex 0672984090 operates within a narrower temperature range (0°C to 50°C) compared to the original part (-55°C to 85°C). Applications requiring operation below 0°C or above 50°C must use the TE Connectivity 5787745-3 instead. Mating cycle data for the Molex part is not specified, whereas the original part is rated for 1500 cycles.

Q: Are there packaging differences between the substitute parts?

A: The TE Connectivity 5787745-3 is supplied in tray packaging. The Molex 0672984090 is also supplied in tray packaging. Both differ from the original 787745-3, which has unspecified packaging. Verify packaging requirements with procurement specifications before finalizing component orders.

Q: Do all substitute parts meet the same compliance standards?

A: The TE Connectivity 5787745-3 and Molex 0672984090 both achieve ROHS3 compliance and carry UL94 V-0 flammability ratings. The original 787745-3 is RoHS non-compliant. For applications subject to RoHS regulations, either substitute part is acceptable. REACH status is unaffected for both substitutes.

Q: What is the difference between the voltage ratings (VAC versus VDC)?

A: The original 787745-3 and TE Connectivity 5787745-3 are rated for 30VAC. The Molex 0672984090 is rated for 30VDC. These represent different voltage specifications. Confirm the voltage type required by your application before selecting a substitute.

Q: Can the higher current rating of the Molex part (1.5A) be used in place of the 1A specification?

A: Yes, from an electrical capacity perspective. The Molex 0672984090 exceeds the original current requirement (1.5A versus 1A per contact), making it suitable for applications where the original 1A rating was specified. However, temperature range limitations must still be observed.
