Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5558342-1

The 5558342-1 is the direct successor to the 558342-1 within the TE Connectivity product line. It maintains identical mechanical and electrical specifications with the exception of Cat5e rating (versus Cat5) and active product status. The 5558342-1 carries RoHS compliance and REACH unaffected status, providing regulatory advantages for new designs. Contact finish thickness remains at 50.0µin (1.27µm), matching the original specification. This part is the preferred substitute for direct replacement applications.

Secondary Substitutes: Assmann WSW A-2004 Series

The Assmann WSW A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, and A-2004-2-3-LP/FS-N connectors provide full mechanical and electrical compatibility. These parts differ primarily in contact finish thickness (15.0µin, 30.0µin, and 50.0µin respectively). All three variants feature polyester housing, phosphor bronze contacts with gold finish, and operating temperature range of -40°C ~ 85°C. All carry ROHS3 compliance and REACH unaffected status. The A-2004-2-3-LP/FS-N variant with 50.0µin finish thickness provides the closest match to the original specification.

Alternative Substitutes: Amphenol ICC (FCI) 94910-001MLF and 95678-001LF

The Amphenol ICC 94910-001MLF (Cat3) and 95678-001LF (Cat5) connectors provide functional compatibility with enhanced EMI shielding through integrated EMI fingers. Both feature phosphor bronze contacts with gold finish and board lock features. Operating temperature range is -40°C ~ 70°C, which is 15°C lower than the original specification. These parts carry RoHS compliance but have REACH affected status. The 95678-001LF maintains Cat5 rating and is suitable for applications where the reduced temperature range is acceptable.

Alternative Substitute: Würth Elektronik 61500814221

The Würth Elektronik 61500814221 provides mechanical compatibility with Cat3 rating. This part features copper alloy contacts with gold finish and polybutylene terephthalate (PBT) housing. Operating temperature range matches the original at -40°C ~ 85°C. ROHS3 compliance and REACH unaffected status are provided. The Cat3 rating represents a lower performance tier suitable for legacy or non-critical applications.

Compliance Considerations:

For new designs requiring regulatory compliance, the 5558342-1, A-2004 series, and 61500814221 are preferred due to RoHS3 compliance and REACH unaffected status. The Amphenol ICC parts carry REACH affected status and require additional regulatory review for certain applications.

Temperature Range Considerations:

Applications requiring the full -40°C ~ 85°C operating range should prioritize the 5558342-1, A-2004 series, or 61500814221. The Amphenol ICC parts are limited to -40°C ~ 70°C.

Frequently Asked Questions (FAQ)

Q: Can the 5558342-1 directly replace the 558342-1?

A: Yes. The 5558342-1 maintains identical mechanical and electrical specifications including 8p8c configuration, 90° right-angle orientation, through-hole solder termination, shielded design, and operating temperature range of -40°C ~ 85°C. The primary difference is Cat5e rating (versus Cat5) and active product status with RoHS compliance.

Q: What is the difference between the Assmann WSW A-2004 variants?

A: The A-2004-2-1-LP/FS-N, A-2004-2-2-LP/FS-N, and A-2004-2-3-LP/FS-N differ only in contact finish thickness: 15.0µin (0.38µm), 30.0µin (0.76µm), and 50.0µin (1.27µm) respectively. All other specifications are identical. The A-2004-2-3-LP/FS-N with 50.0µin thickness matches the original 558342-1 specification.

Q: Are the Amphenol ICC parts suitable for the full temperature range?

A: No. The Amphenol ICC 94910-001MLF and 95678-001LF are rated for -40°C ~ 70°C, which is 15°C lower than the original 558342-1 specification of -40°C ~ 85°C. These parts are suitable only for applications within the reduced temperature range.

Q: What is the significance of EMI fingers in the Amphenol ICC parts?

A: EMI fingers provide enhanced electromagnetic interference shielding through additional contact points with the shielding structure. This feature improves signal integrity in high-noise environments but does not affect mechanical compatibility or pin configuration.

Q: Which substitute part has the best regulatory compliance?

A: The TE Connectivity 5558342-1, Assmann WSW A-2004 series, and Würth Elektronik 61500814221 all carry ROHS3 compliance and REACH unaffected status. The Amphenol ICC parts carry REACH affected status and require additional regulatory review.

Q: Can Cat3-rated parts replace Cat5-rated connectors?

A: Cat3-rated parts (61500814221 and 94910-001MLF) are mechanically and electrically compatible but represent a lower performance tier. They are suitable for legacy applications or non-critical installations but do not support the full bandwidth capabilities of Cat5 networks.

Q: What packaging options are available?

A: The 5558342-1 is supplied in Tray packaging. The Assmann WSW A-2004 series is supplied in Tray packaging. The Amphenol ICC parts are supplied in Tube packaging. The Würth Elektronik 61500814221 is supplied in Tray packaging. Packaging selection depends on production volume and handling requirements.

Q: Are all substitute parts through-hole solder termination?

A: Yes. All listed substitute parts feature through-hole solder termination, matching the original 558342-1 specification.

Q: What is the inventory status of substitute parts?

A: The 5558342-1 has the highest inventory at 2668 pieces. The Würth Elektronik 7499010122 has 4058 pieces available. The Assmann WSW variants range from 768 to 937 pieces. The Amphenol ICC parts range from 749 to 1003 pieces. Inventory levels support immediate availability for production requirements.
