CB50110307 Equivalent & Substitute Parts Reference

Part Overview

The CB50110307 is a 3-circuit barrier block connector manufactured by Eaton Electronics Division, part of the Magnum® CB5000 series. This component functions as a chassis/panel-mounted terminal block with 0.250" (6.35mm) pitch spacing, designed for applications requiring screw-based wire termination with solder turret bottom connections.

The CB50110307 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CB50110307 must satisfy the following mandatory electrical and mechanical parameters:

Critical Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 3
• Pitch spacing: 0.250" (6.35mm)
• Current rating: 10A minimum
• Voltage rating: 300V minimum
• Top termination method: Screws with Captive Plate
• Bottom termination method: Solder Turret
• Barrier configuration: 3 Wall (Tri)
• Mounting configuration: Chassis/Panel compatible
• Insulation material: Thermoplastic
• Flammability rating: UL94 V-0

Allowable Variations:

• Wire gauge range may extend to accommodate the original specification (18-30 AWG minimum)
• Operating temperature maximum may exceed the original specification
• RoHS compliance status may differ
• Product status may transition from obsolete to active

The TE Connectivity AMP Connectors part 3STV-03-006 satisfies all critical matching parameters and allowable variations for direct substitution.

Engineering Selection Recommendations

The 3STV-03-006 from TE Connectivity AMP Connectors qualifies as a direct substitute for the CB50110307 based on complete electrical and mechanical parameter alignment.

Selection Basis:

1. Functional Equivalence: All critical electrical parameters (current rating, voltage rating, wire gauge accommodation) and mechanical parameters (pitch, circuit count, termination methods, barrier configuration) are identical or superior.

2. Product Status Advantage: The substitute part carries active product status, ensuring ongoing availability and supply chain support compared to the obsolete CB50110307.

3. Compliance Enhancement: The 3STV-03-006 achieves RoHS compliance, providing improved environmental and regulatory alignment for new designs or system updates.

4. Thermal Performance: The substitute part's maximum operating temperature of 120°C exceeds the original specification of 105°C, providing additional thermal margin for demanding applications.

5. Physical Compatibility: Identical pitch spacing (0.250"), circuit configuration (3-circuit), and mounting methodology (chassis/panel) ensure direct mechanical interchangeability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 3STV-03-006 be used as a direct replacement for CB50110307 in existing designs?

A: Yes. The 3STV-03-006 matches all critical electrical and mechanical parameters of the CB50110307, including pitch spacing, circuit count, current/voltage ratings, termination methods, and barrier configuration. Physical mounting and electrical performance are directly compatible.

Q: What is the significance of the wire gauge difference (18-30 AWG vs. 16-30 AWG)?

A: The 3STV-03-006 accommodates a wider wire gauge range by including 16 AWG capability. This represents an extension of the original specification and does not restrict compatibility. Applications using 18-30 AWG wire operate within both specifications.

Q: Does the higher operating temperature rating of the 3STV-03-006 affect compatibility?

A: No. The 120°C maximum operating temperature of the 3STV-03-006 exceeds the original 105°C specification. This provides additional thermal margin and does not compromise compatibility with applications designed for the original temperature range.

Q: What is the impact of RoHS compliance differences?

A: The CB50110307 is RoHS non-compliant, while the 3STV-03-006 is RoHS compliant. For new designs or systems subject to RoHS requirements, the 3STV-03-006 provides regulatory compliance. For legacy systems, both parts function identically from an electrical and mechanical standpoint.

Q: Are there any packaging or inventory considerations?

A: The CB50110307 has 822 pieces in stock (obsolete status), while the 3STV-03-006 has 747 pieces in stock (active status). The active status of the substitute part ensures continued availability for future procurement cycles.

Q: How do the series designations differ?

A: The CB50110307 belongs to the Eaton Magnum® CB5000 series, while the 3STV-03-006 belongs to the TE Connectivity #3 Buchanan series. Despite different manufacturer series classifications, both parts satisfy identical functional and mechanical requirements for barrier block terminal applications.
