Key Parameters

Substitute Part Grouping Explanation

Substitution of the 12-675-191 is determined by the following critical parameters that must remain constant:

• Connector Type: Header configuration
• Contact Type: Male pin orientation
• Number of Positions: 12-position arrangement
• Pitch: 0.100" (2.54mm) spacing
• Number of Rows: 2-row configuration
• Row Spacing: 0.300" (7.62mm) inter-row distance
• Mounting Type: Through-hole PCB mounting
• Termination Method: Solder attachment

The identified substitute part 12-680-190T maintains all critical electrical and mechanical parameters. The primary difference is the contact finish material: the substitute uses tin plating instead of gold. Both parts are manufactured by Aries Electronics and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

The 12-680-190T serves as a direct mechanical and electrical substitute for the obsolete 12-675-191. Both connectors maintain identical pitch, row configuration, and mounting specifications required for PCB compatibility.

The substitute part carries active product status, ensuring continued availability and manufacturing support. Both components meet ROHS3 compliance and REACH requirements, satisfying regulatory obligations for new designs and legacy system support.

The contact finish difference—tin versus gold—represents the primary technical distinction. Selection between these finishes depends on application-specific requirements regarding corrosion resistance and signal integrity in the intended operating environment.

Frequently Asked Questions (FAQ)

Q: Can the 12-680-190T directly replace the 12-675-191 on existing PCBs?

A: Yes. Both connectors share identical pitch (0.100"), row count (2), row spacing (0.300"), and through-hole mounting specifications. PCB footprints are mechanically compatible.

Q: What is the functional difference between gold and tin contact finishes?

A: Gold provides superior corrosion resistance and maintains lower contact resistance over extended service life. Tin offers cost efficiency and adequate performance in standard industrial applications. Selection depends on environmental exposure and signal integrity requirements.

Q: Why is the 12-675-191 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 12-680-190T, with active status, represents the current manufacturing equivalent from Aries Electronics.

Q: Are both parts RoHS compliant?

A: Yes. Both the 12-675-191 and 12-680-190T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging is available for the substitute part?

A: The 12-680-190T is supplied in tray packaging, suitable for automated assembly and high-volume production environments.
