Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 406904-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Jack
• Number of Positions/Contacts: 6p4c (RJ11, RJ14)
• Orientation: 90° Angle (Right)
• Mounting Type: Through Hole
• Termination: Solder
• Shielding: Unshielded
• Ratings: Cat3
• Contact Material: Copper Alloy
• Contact Finish: Gold at 50.0µin (1.27µm)
• Operating Temperature Range: -40°C ~ 85°C
• Housing Material: Thermoplastic

The substitute part 5406904-1 maintains full electrical and mechanical compatibility with the original 406904-1 across all specified parameters. The primary distinction is product status: 406904-1 is obsolete, while 5406904-1 is active. Secondary differences include packaging format (Tube for 5406904-1) and mechanical features (Board Lock for 5406904-1 versus Board Guide for 406904-1), along with RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5406904-1 is the direct active equivalent for the obsolete 406904-1 modular connector. Both parts maintain identical electrical and mechanical specifications across all critical parameters including contact configuration, orientation, termination method, and operating temperature range.

Selection Basis:

The 5406904-1 is recommended for new designs and procurement due to active product status. The part provides full functional equivalence with the original 406904-1 while offering improved compliance posture through RoHS compliance certification. The mechanical feature difference (Board Lock versus Board Guide) represents an enhancement in connector retention capability without affecting electrical performance or pin compatibility.

For applications requiring RoHS compliance, the 5406904-1 is the appropriate selection. For legacy systems currently using 406904-1 components, the 5406904-1 provides direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can 5406904-1 be used as a direct replacement for 406904-1 in existing designs?

A: Yes. The 5406904-1 maintains identical electrical and mechanical specifications across all critical parameters. Pin configuration, contact finish, operating temperature range, and solder termination are equivalent. PCB footprint and mounting hole patterns are compatible.

Q: What is the difference between Board Guide and Board Lock features?

A: Board Guide (406904-1) provides basic connector positioning on the PCB. Board Lock (5406904-1) provides enhanced mechanical retention. Both features do not affect electrical performance or contact compatibility.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing standards, not electrical or mechanical performance. Both parts meet identical electrical specifications and operating parameters.

Q: Are the packaging differences significant for component selection?

A: Packaging format (Tube for 5406904-1) affects procurement and handling procedures but does not impact electrical or mechanical compatibility. Component specifications remain identical regardless of packaging format.

Q: Can these connectors be used interchangeably in RJ11 and RJ14 applications?

A: Yes. Both 406904-1 and 5406904-1 are rated for 6p4c (RJ11, RJ14) configurations. The 4-contact configuration supports both RJ11 and RJ14 standard implementations.

Q: What is the contact finish thickness specification?

A: Both parts specify 50.0µin (1.27µm) gold plating over copper alloy base material. This thickness ensures consistent contact resistance and corrosion resistance across the operating temperature range.

Q: Are there any temperature-related limitations for these connectors?

A: Both parts operate across the identical temperature range of -40°C to 85°C. No derating or thermal management modifications are required when substituting between these parts.
