3240-24-00 Equivalent & Substitute Parts

Part Overview

The 3240-24-00 is a 24-position ribbon cable DIP header connector manufactured by CNC Tech, designed for IDC (Insulation Displacement Connector) through-hole applications. This connector features a vertical orientation with feed-through capability and gold-plated contacts. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the 3240-24-00 is determined by strict equivalence across the following critical parameters:

  • Connector Configuration: 24-position, 2-row ribbon cable header with IDC termination
  • Pitch Specifications: Cable pitch of 0.025" (0.64mm) and board-side pitch of 0.050" (1.27mm) with matching row spacing
  • Mounting and Orientation: Through-hole vertical mounting with feed-through capability
  • Electrical and Environmental Compliance: ROHS3 compliance and MSL rating compatibility

The FFMD-12-01 from Samtec Inc. meets all these critical parameters, establishing it as a direct functional equivalent despite differences in contact finish material and manufacturer series designation.

Engineering Selection Recommendations

The FFMD-12-01 is suitable as a substitute for the 3240-24-00 based on the following engineering criteria:

Mechanical Compatibility: Both connectors share identical pitch specifications, row configuration, and through-hole mounting geometry, ensuring direct PCB footprint compatibility.

Electrical Compliance: Both parts maintain ROHS3 compliance and support the same IDC termination method with 24-position ribbon cable connectivity.

Product Status Advantage: The FFMD-12-01 is classified as active product status, providing ongoing manufacturer support, availability, and supply chain continuity compared to the obsolete 3240-24-00.

Contact Material Difference: The FFMD-12-01 uses tin contact finish versus the gold finish of the original part. This difference does not affect functional substitution for standard signal and power applications within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Are the 3240-24-00 and FFMD-12-01 mechanically interchangeable?

A: Yes. Both connectors feature identical 24-position, 2-row configurations with 0.025" cable pitch and 0.050" board-side pitch. PCB footprints and mounting hole patterns are equivalent for through-hole installation.

Q: Does the contact finish difference (gold vs. tin) affect substitution?

A: The contact finish difference does not prevent functional substitution. Both finishes provide adequate electrical conductivity for standard signal and power applications. Selection between them depends on specific application requirements for contact resistance and environmental exposure.

Q: What is the significance of the FFMD-12-01 being active product status?

A: Active product status indicates ongoing manufacturer support, documented availability, and supply chain reliability. This is advantageous when replacing obsolete components, as it ensures long-term procurement viability and access to technical documentation.

Q: Are there any packaging differences between these connectors?

A: The 3240-24-00 packaging is not specified in available data. The FFMD-12-01 is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Can the FFMD-12-01 be used in existing designs without PCB modification?

A: Yes, provided the original design accommodates the specified pitch and mounting geometry of the 3240-24-00. The FFMD-12-01 maintains these specifications, eliminating the need for PCB redesign.
