CNC Tech 3230-12-0102-00 Equivalent & Substitute Parts

Part Overview

The CNC Tech 3230-12-0102-00 is a 12-position rectangular socket connector with IDC (Insulation Displacement Contact) termination and gold plating. This connector features a 0.050" (1.27mm) pitch in a 2-row configuration with feed-through and polarizing key capabilities, designed for ribbon cable applications.

The 3230-12-0102-00 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector type.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, providing superior supply chain continuity compared to the obsolete 3230-12-0102-00.

The Samtec FFSD-06-01-N offers the closest functional alignment, retaining the polarizing key feature present in the original part and maintaining ROHS3 compliance. This part is available in high inventory (7279 pcs) and is REACH unaffected.

The Amphenol ICC 20021444-00012T4LF (Minitek127® series) provides an alternative with active product status and substantial inventory availability (1767 pcs). This part is RoHS compliant and REACH affected. The absence of a polarizing key feature should be evaluated against specific application requirements.

Both parts support 30 AWG ribbon cable and maintain gold contact finish specifications suitable for the electrical requirements of the original design.

Frequently Asked Questions (FAQ)

Q: Can the Samtec FFSD-06-01-N directly replace the CNC Tech 3230-12-0102-00?

A: The Samtec FFSD-06-01-N meets all critical electrical and mechanical parameters: 12-position IDC configuration, 0.050" pitch, 2-row arrangement, gold contact finish, and free-hanging in-line mounting. The retention of the polarizing key feature provides additional design compatibility. Physical form factor and mating interface alignment should be confirmed for your specific application.

Q: What is the difference between the two substitute parts?

A: Both parts share identical electrical specifications (12-position, 0.050" pitch, IDC termination, gold finish). The primary difference is the polarizing key feature: the Samtec FFSD-06-01-N includes it, while the Amphenol ICC 20021444-00012T4LF does not. Compliance profiles differ slightly (Samtec is ROHS3/REACH unaffected; Amphenol is RoHS/REACH affected).

Q: Are there wire gauge considerations for substitution?

A: The original part does not specify wire gauge. Both substitute parts are rated for 30 AWG ribbon cable. Confirm that your existing ribbon cable gauge is compatible with 30 AWG specifications.

Q: What is the significance of contact finish thickness differences?

A: The original part specifies flash gold plating. Both substitute parts provide 10.0µin (0.25µm) gold plating, which exceeds flash thickness and provides enhanced durability and contact reliability for IDC termination applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. The Samtec FFSD-06-01-N is ROHS3 compliant, matching the original part's certification. The Amphenol ICC 20021444-00012T4LF is RoHS compliant. Both meet regulatory requirements for restricted substance control.
