Substitute Part Grouping Explanation

Substitute parts for the SUSB are grouped based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Mechanical Parameters: Connector type (USB-A receptacle), contact count (4 positions), mounting configuration (through-hole, right-angle, horizontal), termination method (solder), and board lock feature presence.

Electrical Parameters: Shielding requirement (shielded), contact finish (gold or gold-palladium), mating cycle rating (1500 cycles), and material flammability (UL94 V-0).

Compliance Considerations: RoHS status and REACH compliance affect suitability for new designs versus legacy system support.

Substitute parts are categorized as:

Direct Manufacturer Substitute: SUSBX (Switchcraft Inc.) — identical specifications with improved RoHS3 compliance
Similar Manufacturer Parts: USB-A-S-F-B-TH (Samtec Inc.) — active product with USB 2.0 specification and extended operating temperature range
Parametric Equivalents: TE Connectivity AMP Connectors (1-292303-2, 1775545-1, 292303-4, 292303-5, 292303-6, 292303-8) and EDAC Inc. (690A104-123-020, 690A104-123-021) — all meeting core mechanical and electrical requirements with active product status

Engineering Selection Recommendations

For Legacy System Support (Obsolete Design Continuation): SUSBX (Switchcraft Inc.) provides the closest functional equivalent to the SUSB with identical mechanical and electrical specifications. SUSBX maintains obsolete product status but offers improved ROHS3 compliance, making it suitable for field service and repair applications where design continuity is required.

For New Designs with Active Product Requirement: TE Connectivity AMP Connectors 292303 series (292303-4, 292303-5, 292303-6, 292303-8) and 1-292303-2 are recommended. These parts maintain all core mechanical parameters, provide active product status, and offer RoHS compliance. The 292303 series variants differ in packaging (bulk, tube) and insulation color (black, natural), allowing selection based on procurement and assembly requirements.

For Extended Operating Temperature Range: USB-A-S-F-B-TH (Samtec Inc.) specifies operating temperature range of -50°C to 85°C, exceeding the SUSB baseline. This part is suitable for applications requiring enhanced thermal performance while maintaining all mechanical and electrical compatibility.

For Higher Current Rating: 690A104-123-020 and 690A104-123-021 (EDAC Inc., 690A series) provide 1.5A current rating per contact, compared to the SUSB baseline. These parts are active products with ROHS3 compliance and are available in white (690A104-123-020) or black (690A104-123-021) insulation color.

Compliance Consideration: The SUSB is RoHS non-compliant. All substitute parts listed are RoHS compliant or ROHS3 compliant, supporting regulatory requirements for new production and export markets.

Frequently Asked Questions (FAQ)

Q: Can SUSBX be used as a direct replacement for SUSB in existing designs? A: Yes. SUSBX maintains identical mechanical and electrical specifications, including 4-position through-hole right-angle configuration, solder termination, board lock feature, shielding, and 1500 mating cycle rating. The primary difference is improved ROHS3 compliance. Footprint and functional compatibility are preserved.

Q: What is the difference between TE Connectivity 292303 variants (292303-4, 292303-5, 292303-6, 292303-8)? A: All 292303 variants share identical electrical and mechanical specifications. Differences are in packaging format (bulk or tube) and insulation color (black or natural). Selection depends on procurement quantity, assembly process requirements, and visual identification needs. All variants are active products with RoHS compliance.

Q: Is USB 2.0 specification required for SUSB replacement? A: USB 2.0 specification is provided in substitute part datasheets but is not a mandatory substitution criterion for the SUSB. The SUSB does not specify USB version. Parts without explicit USB 2.0 designation (such as 1775545-1) remain mechanically and electrically compatible based on core parameters: 4-position receptacle, through-hole right-angle mounting, solder termination, and board lock feature.

Q: Can I use 690A104-123-020 or 690A104-123-021 in place of SUSB? A: Yes, with consideration for current rating. The 690A series provides 1.5A per contact versus unspecified current rating for SUSB. Mechanical compatibility is maintained: 4-position USB-A receptacle, through-hole right-angle, solder termination, board lock, and shielding. Operating temperature range is -40°C to 85°C. Insulation color differs (white or black) but does not affect electrical function.

Q: What is the inventory status for substitute parts? A: SUSBX: 1003 pcs. USB-A-S-F-B-TH: 2326 pcs. TE Connectivity 1-292303-2: 733 pcs. TE Connectivity 1775545-1: 914 pcs. TE Connectivity 292303-4: 3826 pcs. TE Connectivity 292303-5: 1322 pcs. TE Connectivity 292303-6: 6580 pcs. TE Connectivity 292303-8: 976 pcs. EDAC 690A104-123-020: 995 pcs. EDAC 690A104-123-021: 747 pcs. All parts are listed as new original in stock.

Q: Are there packaging considerations when selecting a substitute? A: Yes. SUSBX is supplied in bulk packaging. USB-A-S-F-B-TH is supplied in tray. TE Connectivity 292303-4 and 292303-6 are bulk. TE Connectivity 292303-5 is tube. TE Connectivity 1-292303-2 is bulk. Packaging affects handling, storage, and assembly line integration. Confirm packaging compatibility with your procurement and manufacturing processes.

Q: What compliance certifications apply to substitute parts? A: All substitute parts carry UL94 V-0 material flammability rating, matching the SUSB. RoHS compliance status varies: SUSBX, USB-A-S-F-B-TH, 292303-6, and 690A series are ROHS3 compliant. TE Connectivity 1-292303-2, 1775545-1, 292303-4, 292303-5, and 292303-8 are RoHS compliant. REACH status is unaffected or vendor undefined across all parts. Confirm compliance requirements for your target market and application.
