Substitute Part Grouping Explanation

Substitution of the TE Connectivity 406526-1 is based on strict equivalence across all critical electrical and mechanical parameters. The identified substitute part, 5406526-1, maintains identical specifications in the following key areas:

Electrical Equivalence:

• 8p8c (RJ45/Ethernet) contact configuration
• Cat5 performance rating
• Phosphor bronze contacts with 50.0µin gold finish
• Unshielded design

Mechanical Equivalence:

• 90° right-angle orientation
• Through-hole mounting
• Solder termination
• Thermoplastic housing with board guide feature
• Tab direction (up)

Environmental & Compliance Equivalence:

• Operating temperature range: -40°C ~ 85°C
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8536.69.4040

The primary difference between the main part and substitute is packaging format: 406526-1 is supplied in standard packaging, while 5406526-1 is supplied in tray packaging. This distinction does not affect functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (406526-1): The TE Connectivity 406526-1 is the specified part number and remains the primary selection for applications requiring standard packaging. This part is active in production, ROHS3 compliant, and maintains full regulatory compliance with ECCN EAR99 classification.

Substitute Selection (5406526-1): The 5406526-1 substitute part is functionally and electrically equivalent to the main part across all critical parameters. Selection of this substitute is appropriate when:

• Tray packaging format is acceptable for assembly operations
• Higher inventory availability (4691 pieces) addresses supply chain requirements
• REACH Unaffected status provides additional regulatory clarity compared to the main part's Vendor Undefined status
• Cost or logistics considerations favor bulk tray packaging

Both parts are active products with identical electrical performance, mechanical compatibility, and environmental operating specifications. The choice between them is determined by packaging requirements and regulatory documentation preferences, not by functional or performance differences.

Frequently Asked Questions (FAQ)

Q: Can 5406526-1 be used as a direct replacement for 406526-1 in production assemblies?

A: Yes. The 5406526-1 is electrically and mechanically equivalent to 406526-1 across all critical parameters including connector type, pin configuration, orientation, termination method, and operating temperature range. The only difference is packaging format (tray versus standard). Both parts are ROHS3 compliant and maintain identical contact specifications.

Q: What is the difference between standard packaging and tray packaging?

A: Standard packaging and tray packaging differ only in the physical container format used for shipment and storage. Tray packaging (5406526-1) is typically used for higher-volume orders and automated assembly processes. Standard packaging (406526-1) is used for smaller quantities. The connector itself is identical in both cases.

Q: Are there any compatibility issues when substituting 5406526-1 for 406526-1?

A: No compatibility issues exist. Both parts feature identical 8p8c (RJ45/Ethernet) pin configurations, 90° right-angle orientation, through-hole mounting, and solder termination. PCB layout, assembly processes, and electrical performance remain unchanged.

Q: Does the REACH status difference affect substitution eligibility?

A: The REACH status difference (Vendor Undefined for 406526-1 versus REACH Unaffected for 5406526-1) does not affect functional substitution. The 5406526-1 provides clearer regulatory documentation. Both parts comply with applicable environmental regulations for their respective classifications.

Q: What is the operating temperature range for both parts?

A: Both 406526-1 and 5406526-1 operate across the identical temperature range of -40°C to 85°C. This specification is maintained regardless of packaging format.

Q: Are both parts suitable for Cat5 Ethernet applications?

A: Yes. Both parts are rated for Cat5 performance and feature identical contact materials (phosphor bronze), contact finish (gold, 50.0µin thickness), and unshielded design. They are functionally equivalent for Cat5 networking and telecommunications applications.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements. This applies to both 406526-1 and 5406526-1.

Q: Can these connectors be used in high-temperature environments?

A: Both connectors are rated for operation up to 85°C. Applications requiring operation above this temperature require alternative connector specifications outside this product family.
