Engineering Selection Recommendations

The 3STV-02-006 from TE Connectivity AMP Connectors qualifies as a direct substitute for the CB50110207. All critical electrical and mechanical parameters match exactly. The substitute part offers the following advantages:

Product Status: The 3STV-02-006 is classified as active, ensuring continued availability and supply chain support, whereas the CB50110207 is obsolete.

Compliance: The 3STV-02-006 is RoHS compliant, meeting current regulatory requirements. The CB50110207 is RoHS non-compliant.

Operating Temperature: The 3STV-02-006 supports an extended operating temperature range of -40°C to 120°C compared to the CB50110207 range of -40°C to 105°C.

Wire Gauge Compatibility: The 3STV-02-006 accepts wire gauges from 16-30 AWG, providing broader compatibility than the CB50110207 specification of 18-30 AWG.

Selection of the 3STV-02-006 is appropriate for applications requiring the CB50110207 specification, with the added benefit of improved regulatory compliance and extended operational parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3STV-02-006 be used as a direct replacement for CB50110207 in existing designs?

A: Yes. The 3STV-02-006 matches all critical electrical and mechanical parameters of the CB50110207, including circuit count, pitch spacing, current and voltage ratings, termination types, and barrier configuration. Physical dimensions and mounting interfaces are compatible.

Q: What is the significance of the wire gauge difference between these parts?

A: The CB50110207 accepts 18-30 AWG wire, while the 3STV-02-006 accepts 16-30 AWG wire. The 3STV-02-006 specification encompasses the full range of the CB50110207, making it compatible with any wire gauge previously used with the original part.

Q: Why is the operating temperature range different?

A: The 3STV-02-006 supports operation to 120°C, while the CB50110207 is rated to 105°C. This represents an extended capability of the substitute part. Applications operating within the CB50110207 temperature range are fully supported by the 3STV-02-006.

Q: What does RoHS compliance mean for this substitution?

A: RoHS compliance indicates the 3STV-02-006 meets restrictions on hazardous substances in electrical and electronic equipment. The CB50110207 is non-compliant. For new designs or applications subject to RoHS requirements, the 3STV-02-006 is the appropriate selection.

Q: Are the flange and mounting configurations identical?

A: Yes. Both parts feature a flange and support chassis and panel mounting types. Physical mounting interfaces are compatible.

Q: Is inventory availability a consideration?

A: The CB50110207 has 741 pieces in stock as new original inventory. The 3STV-02-006 has 781 pieces in stock. Both parts are currently available, though the CB50110207 is obsolete and future availability cannot be assured.

Q: What is the base product number for the 3STV-02-006?

A: The base product number is 3STV, part of the TE Connectivity #3 Buchanan series barrier block connectors.
