CB50111207 Equivalent & Substitute Parts Reference

Part Overview

The CB50111207 is a 12-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 CB50111207 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and repairs.

• 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

Secondary Compatibility Factors:

• Wire gauge range must accommodate 18-30 AWG minimum
• Operating temperature range must support -40°C to 105°C minimum
• Physical form factor and flange design must be compatible with existing mounting

The TE Connectivity AMP Connectors part 3STV-12-006 meets all primary and secondary criteria for direct substitution with the CB50111207.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3STV-12-006 is a direct functional equivalent to the obsolete Eaton CB50111207. All critical electrical parameters, mechanical dimensions, and termination methods are identical or exceed the original specification.

Key Selection Factors:

1. Product Status: The CB50111207 is obsolete. The 3STV-12-006 is in active production, ensuring long-term availability and supply chain continuity.

2. Electrical Compatibility: Both parts operate at 10A, 300V with identical wire gauge accommodation (3STV-12-006 supports 16-30 AWG, which exceeds the 18-30 AWG requirement).

3. Mechanical Compatibility: Identical pitch spacing (0.250"), circuit count (12), barrier configuration (3 Wall Tri), and mounting type (Chassis/Panel) ensure direct form-fit-function replacement.

4. Regulatory Compliance: Both parts meet UL94 V-0 flammability requirements. The 3STV-12-006 achieves RoHS compliance, whereas the CB50111207 is RoHS non-compliant.

5. Thermal Performance: The 3STV-12-006 supports -40°C to 120°C operating range, exceeding the CB50111207 specification of -40°C to 105°C.

6. Termination Methods: Screw-based top termination with captive plate and solder turret bottom termination are identical, ensuring compatibility with existing PCB layouts and wire harness assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 3STV-12-006 be used as a direct replacement for CB50111207 in existing designs?

A: Yes. The 3STV-12-006 meets all electrical, mechanical, and functional requirements of the CB50111207. Identical pitch spacing, circuit count, current/voltage ratings, and termination methods ensure direct compatibility without design modification.

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

A: The 3STV-12-006 accepts a wider wire gauge range (16-30 AWG) compared to the CB50111207 (18-30 AWG). This provides additional flexibility for wire selection while maintaining full compatibility with the original 18-30 AWG specification.

Q: Does the higher operating temperature rating of the 3STV-12-006 affect compatibility?

A: No. The 3STV-12-006 supports -40°C to 120°C, which exceeds the CB50111207 range of -40°C to 105°C. This represents an improvement in thermal capability with no negative impact on compatibility.

Q: Are there any RoHS compliance considerations when substituting?

A: The CB50111207 is RoHS non-compliant, while the 3STV-12-006 is RoHS compliant. For new designs or systems requiring RoHS compliance, the 3STV-12-006 is the appropriate selection. For legacy system repairs, both parts are functionally equivalent.

Q: How do the solder turret bottom terminations compare between these parts?

A: Both parts use solder turret bottom termination, ensuring identical PCB mounting and soldering characteristics. No modifications to PCB footprints or assembly processes are required.

Q: Is the 3 Wall (Tri) barrier configuration identical between both parts?

A: Yes. Both the CB50111207 and 3STV-12-006 feature 3 Wall (Tri) barrier configuration, providing identical circuit isolation and electrical safety characteristics.

Q: What is the inventory status of the 3STV-12-006?

A: The 3STV-12-006 is in active production with 1068 pieces available in new original stock, ensuring reliable supply availability for both immediate and future requirements.
