TE Connectivity 406549-4 Modular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 406549-4 is an 8-position 8-contact (8p8c) modular jack connector with right-angle orientation, designed for Ethernet and RJ45 applications. This shielded connector features an EMI finger, phosphor bronze contacts with gold finish, and through-hole solder termination. The connector is rated for Cat5 performance and operates across the temperature range of -40°C to 85°C.

The 406549-4 is an active product with 826 units currently in stock. Substitute parts are identified to address packaging variations and compliance requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 406549-4 is determined by strict equivalence across all electrical and mechanical parameters. The identified substitute part maintains identical specifications for connector type, contact configuration, orientation, mounting method, termination style, shielding characteristics, performance rating, contact materials and finish, operating temperature range, housing material, port and row configuration, tab direction, board guide feature, and LED color indication.

The primary distinction between the main part and its substitute is packaging format and compliance certification status. Both parts share the same base product number (406549) and are manufactured by TE Connectivity AMP Connectors as active products.

Key Parameters Determining Substitution:

• 8p8c (RJ45, Ethernet) contact configuration
• 90° right-angle orientation
• Through-hole solder termination
• Shielded design with EMI finger
• Cat5 performance rating
• Phosphor bronze contacts with gold finish (50.0µin thickness)
• Operating temperature range: -40°C to 85°C
• Thermoplastic housing with board guide

Parameter Comparison

Engineering Selection Recommendations

Both the 406549-4 and 2-406549-4 are active products from TE Connectivity AMP Connectors with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

Compliance Requirements: The 2-406549-4 substitute part is RoHS Compliant with REACH Unaffected status, whereas the 406549-4 main part is RoHS non-compliant with Vendor Undefined REACH status. Applications subject to RoHS or REACH regulatory requirements must use the 2-406549-4 substitute.

Packaging Format: The 2-406549-4 is supplied in Tray packaging, while the 406549-4 packaging format is not specified. Packaging selection depends on assembly process requirements and inventory management protocols.

Availability: The 2-406549-4 substitute has higher inventory availability (2100 units) compared to the 406549-4 (826 units), which may influence procurement decisions for high-volume applications.

Both parts maintain identical performance across all electrical and mechanical parameters, including Cat5 rating, operating temperature range, contact configuration, and shielding characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 406549-4 and 2-406549-4 electrically identical?

A: Yes. Both parts are 8p8c (RJ45, Ethernet) modular jack connectors with identical electrical specifications, including Cat5 performance rating, phosphor bronze contacts with 50.0µin gold finish, and shielded design with EMI finger. Operating temperature range, contact configuration, and all electrical parameters are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Tray for 2-406549-4 versus unspecified for 406549-4) and compliance certifications. The 2-406549-4 is RoHS Compliant and REACH Unaffected, while the 406549-4 is RoHS non-compliant with Vendor Undefined REACH status. All mechanical and electrical specifications are identical.

Q: Can I use 2-406549-4 as a direct replacement for 406549-4?

A: Yes, the 2-406549-4 is a direct functional substitute for the 406549-4. Both parts have identical connector type, contact configuration, orientation, mounting method, termination style, shielding, and performance rating. Substitution is valid from an engineering standpoint.

Q: Which part should I select for RoHS-compliant applications?

A: The 2-406549-4 must be used for applications requiring RoHS compliance. The 406549-4 is RoHS non-compliant and is not suitable for RoHS-regulated applications.

Q: Are there any temperature or performance differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and are rated for Cat5 performance. All electrical and thermal specifications are equivalent.

Q: What is the packaging difference, and does it affect compatibility?

A: The 2-406549-4 is supplied in Tray packaging, while the 406549-4 packaging is not specified. Packaging format does not affect electrical or mechanical compatibility. Selection should be based on assembly process requirements and inventory management needs.

Q: Are both parts currently available?

A: Yes, both parts are active products. The 2-406549-4 has 2100 units in stock, while the 406549-4 has 826 units in stock. Availability may vary based on current procurement status.

Q: Do these connectors support the same mounting and termination methods?

A: Yes. Both parts use through-hole mounting with solder termination. The 90° right-angle orientation, board guide feature, and tab direction (Up) are identical across both parts.
