Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB50110707 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 7
• Pitch: 0.250" (6.35mm)
• Current rating: 10A
• Voltage rating: 300V
• Top termination: Screws with Captive Plate
• Bottom termination: Solder Turret
• Barrier type: 3 Wall (Tri)
• Mounting type: Chassis, Panel
• Material flammability rating: UL94 V-0

Allowable Variations:

• Wire gauge range: Substitute parts may accommodate equal or broader wire gauge specifications
• Operating temperature: Substitute parts may exceed the original specification
• Product status: Active status preferred for ongoing availability
• RoHS compliance: Enhanced compliance status acceptable
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align

The TE Connectivity AMP Connectors part number 3STV-07-006 meets all mandatory matching criteria and represents a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 3STV-07-006 is a direct functional equivalent to the CB50110707 for applications requiring 7-circuit barrier block connectors with 0.250" pitch, 10A current capacity, and 300V voltage rating.

Selection Basis:

The 3STV-07-006 maintains electrical and mechanical equivalence across all critical parameters. The wire gauge specification of 16-30 AWG provides compatibility with the original 18-30 AWG range while extending capability to smaller gauge conductors. The operating temperature range of -40°C to 120°C exceeds the original -40°C to 105°C specification, providing enhanced thermal margin for demanding applications.

The transition from obsolete to active product status ensures continued component availability and supply chain reliability. The RoHS compliant status of the 3STV-07-006 aligns with modern regulatory requirements while maintaining full functional compatibility with legacy system designs.

Both components share identical electrical ratings, termination methods, barrier configuration, and mounting characteristics, supporting direct substitution in existing designs without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 3STV-07-006 be used as a direct replacement for CB50110707 in existing assemblies?

A: Yes. The 3STV-07-006 maintains equivalent electrical ratings (10A, 300V), identical pitch (0.250"), matching termination methods (screw top, solder turret bottom), and identical barrier configuration (3 Wall Tri). Physical mounting and electrical performance are equivalent.

Q: What is the significance of the wire gauge difference between 18-30 AWG and 16-30 AWG?

A: The 3STV-07-006 specification of 16-30 AWG encompasses the original 18-30 AWG range and extends compatibility to 16 AWG conductors. This represents an allowable variation that does not restrict the original application range.

Q: Why is the operating temperature range different between the two parts?

A: The 3STV-07-006 operates to 120°C maximum versus 105°C for the CB50110707. This represents an enhanced specification that provides additional thermal margin. Applications designed for the original -40°C to 105°C range operate within the 3STV-07-006 specification.

Q: Does RoHS compliance status affect substitution eligibility?

A: RoHS compliance is not a substitution-limiting factor. The 3STV-07-006 RoHS compliant status represents an improvement over the non-compliant CB50110707. Both parts maintain identical electrical and mechanical characteristics.

Q: Are there any packaging or mounting differences between these components?

A: No. Both components feature identical mounting type (Chassis, Panel), flange configuration, and physical form factor. The 3STV-07-006 is a direct mechanical substitute.

Q: What is the basis for determining substitution compatibility?

A: Substitution is based on equivalence of terminal block type, circuit count, pitch, current and voltage ratings, termination methods, barrier configuration, and mounting type. All these parameters are identical between the CB50110707 and 3STV-07-006.
