Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB50110407 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier block configuration
• Number of circuits: 4 circuits
• Pitch spacing: 0.250" (6.35mm)
• Current rating: 10A minimum
• Voltage rating: 300V minimum
• Top termination: Screws with captive plate
• Bottom termination: Solder turret
• Barrier type: 3 wall (tri) configuration
• Mounting capability: Chassis and panel mounting

The TE Connectivity AMP Connectors part number 3STV-04-006 satisfies all mandatory matching parameters. This part maintains identical electrical and mechanical specifications while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3STV-04-006 is a direct functional equivalent to the obsolete Eaton CB50110407. Selection of the 3STV-04-006 is supported by the following engineering factors:

Electrical and Mechanical Equivalence: All critical electrical parameters (10A current rating, 300V voltage rating) and mechanical specifications (4-circuit barrier block, 0.250" pitch, screw termination with solder turret) are identical between the two parts.

Product Status: The CB50110407 is classified as obsolete, whereas the 3STV-04-006 is active production. This distinction ensures long-term availability and supply chain continuity for new designs and ongoing maintenance applications.

Compliance Improvement: The 3STV-04-006 is RoHS compliant, addressing regulatory requirements that may apply to end-use applications. The CB50110407 is RoHS non-compliant.

Operating Temperature Range: The 3STV-04-006 supports an extended upper operating temperature limit of 120°C compared to the CB50110407 at 105°C, providing additional thermal margin in applications approaching the upper temperature boundary.

Wire Gauge Compatibility: The 3STV-04-006 accepts wire gauges from 16-30 AWG, compared to 18-30 AWG for the CB50110407. This expanded range provides greater flexibility in wire selection without compromising electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 3STV-04-006 be used as a direct replacement for the CB50110407 in existing designs?

A: Yes. The 3STV-04-006 maintains identical electrical ratings (10A, 300V), mechanical configuration (4-circuit barrier block, 0.250" pitch), and termination methods (screw top, solder turret bottom). Physical dimensions and mounting interfaces are equivalent, enabling direct substitution in existing PCB layouts and chassis assemblies.

Q: What are the key differences between these two parts?

A: The primary differences are product status, compliance, and operating temperature range. The 3STV-04-006 is active production (versus obsolete), RoHS compliant (versus non-compliant), and rated to 120°C (versus 105°C). The 3STV-04-006 also accepts a wider wire gauge range (16-30 AWG versus 18-30 AWG).

Q: Are there any compatibility concerns with PCB mounting or soldering?

A: No. Both parts feature identical solder turret bottom termination and flange-based mounting configuration. Existing PCB footprints, solder pad layouts, and mounting hole patterns are compatible without modification.

Q: Does the extended operating temperature range of the 3STV-04-006 affect electrical performance?

A: No. The extended temperature rating to 120°C does not alter the electrical specifications. Current and voltage ratings remain 10A and 300V respectively across the full operating temperature range.

Q: Is the 3STV-04-006 suitable for applications requiring RoHS compliance?

A: Yes. The 3STV-04-006 is RoHS compliant, meeting the Restriction of Hazardous Substances directive requirements. The CB50110407 is RoHS non-compliant and should not be used in applications with RoHS compliance mandates.

Q: Can wire gauges smaller than 18 AWG be used with the 3STV-04-006?

A: Yes. The 3STV-04-006 accepts wire gauges down to 16 AWG, whereas the CB50110407 minimum is 18 AWG. This expanded range allows use of 16 AWG wire without exceeding the connector's wire gauge specification.
