Substitute Part Grouping Explanation

Substitute parts for the DUSBX are qualified based on strict parametric equivalence across the following critical dimensions:

Connector Architecture: All substitutes maintain USB-A (USB TYPE-A) stacked receptacle configuration with 8-position contact count and receptacle gender, ensuring mechanical and electrical compatibility.

Mounting Specification: All qualified substitutes feature through-hole, right-angle mounting with horizontal mounting feature and solder termination, matching the original part's PCB integration requirements.

Functional Features: Board lock functionality is preserved across all substitutes to maintain mechanical retention during mating cycles.

Electrical & Mechanical Durability: All substitutes meet or exceed the 1500 mating cycle specification and maintain shielded construction for EMI protection.

Regulatory Compliance: All substitutes are ROHS3 compliant and REACH unaffected, matching the environmental and regulatory status of the main part.

Contact & Material Specifications: Gold or gold-palladium contact finish and UL94 V-0 flammability rating are maintained across substitutes where specified.

Moisture Sensitivity: All substitutes maintain MSL 1 (Unlimited) rating, ensuring compatibility with standard storage and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full regulatory compliance (ROHS3, REACH unaffected). Selection among DUSBX, 292323-6, and USB-A-D-F-W-TH is determined by parametric equivalence and availability requirements.

The 292323-6 (TE Connectivity AMP Connectors) provides the most comprehensive electrical specification documentation, including operating temperature range (-55°C ~ 85°C), rated voltage (30VAC), and current rating (1A per contact). This part is suitable for applications requiring explicit thermal and electrical performance verification.

The USB-A-D-F-W-TH (Samtec Inc.) maintains equivalent mechanical and mounting specifications with operating temperature range (-50°C ~ 85°C) and rated voltage (30VAC). The insulation color differs (white versus black), which may be relevant for visual identification in assembly or maintenance contexts.

The DUSBX (Switchcraft Inc.) serves as the primary reference part with confirmed UL94 V-0 flammability rating and black insulation color. All three parts are mechanically and electrically interchangeable within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts share identical connector type (USB-A stacked receptacle), contact count (8), mounting configuration (through-hole, right-angle, horizontal), and board lock features. PCB footprints and mating interfaces are equivalent.

Q: What is the significance of the insulation color difference?

A: Insulation color (black for DUSBX and 292323-6; white for USB-A-D-F-W-TH) is a visual identifier and does not affect electrical or mechanical function. Selection may depend on assembly documentation, color-coding standards, or visual traceability requirements.

Q: Can I substitute based on contact finish alone?

A: No. While contact finish (gold or gold-palladium) affects corrosion resistance and long-term reliability, substitution must be based on the complete parameter set. All three parts meet the shielded, gold-plated contact requirement.

Q: What does "board lock" mean in this context?

A: Board lock is a mechanical retention feature that secures the connector to the PCB during mating and unmating cycles, preventing accidental disconnection. All three parts include this feature.

Q: Are there differences in packaging that affect selection?

A: The DUSBX is listed as "-" (packaging not specified), while 292323-6 and USB-A-D-F-W-TH are supplied in bulk packaging. Packaging differences do not affect component function but may influence procurement quantity and handling procedures.

Q: Which part should I select for high-temperature applications?

A: The 292323-6 specifies operating temperature range -55°C ~ 85°C, providing the widest thermal specification. The USB-A-D-F-W-TH operates -50°C ~ 85°C. The DUSBX does not specify operating temperature. For applications requiring explicit thermal performance, 292323-6 is the documented choice.

Q: Do all parts meet the same mating cycle specification?

A: Yes. All three parts are rated for 1500 mating cycles, ensuring equivalent mechanical durability and connector lifespan.
