Key Parameters

Substitute Part Grouping Explanation

Substitution of the CNC Tech 3220-08-0300-99 is based on the following critical parameters that must remain consistent:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Arrangement: 8 positions in 2 rows
• Pitch Specification: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount construction
• Shrouding Design: Shrouded 4-wall configuration
• Termination Method: Solder termination
• Fastening Mechanism: Push-Pull fastening
• Regulatory Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The Samtec Inc. SHF-104-01-L-D-SM meets all these critical parameters and is classified as an active product, providing a viable substitute for the obsolete CNC Tech connector.

Parameter Comparison

Engineering Selection Recommendations

The Samtec Inc. SHF-104-01-L-D-SM is a direct substitute for the obsolete CNC Tech 3220-08-0300-99. Both connectors maintain identical mechanical and electrical interface specifications, including pitch, position count, mounting type, and shrouding configuration.

The Samtec connector offers enhanced performance characteristics: extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), increased current rating (3A versus 1A), and improved contact durability through phosphor bronze material with gold plating. Both products meet UL94 V-0 flammability requirements and ROHS3 compliance standards.

The Samtec SHF-104-01-L-D-SM is actively manufactured and maintained in production inventory, ensuring long-term availability and supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Are the CNC Tech 3220-08-0300-99 and Samtec SHF-104-01-L-D-SM mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.050"/1.27mm), position count (8 positions in 2 rows), row spacing, shrouding configuration, and mounting footprint. They are mechanically interchangeable in board-to-cable/wire applications.

Q: What are the key electrical differences between these connectors?

A: The Samtec connector supports higher current (3A versus 1A) and operates across a wider temperature range (-55°C to 125°C versus -40°C to 105°C). Contact material differs: CNC Tech uses brass with tin plating; Samtec uses phosphor bronze with gold plating on mating contacts.

Q: Are both connectors RoHS compliant?

A: Yes. Both the CNC Tech 3220-08-0300-99 and Samtec SHF-104-01-L-D-SM are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the packaging format for the Samtec substitute?

A: The Samtec SHF-104-01-L-D-SM is supplied in tube packaging.

Q: Why is the CNC Tech connector listed as obsolete?

A: The CNC Tech 3220-08-0300-99 has been discontinued by the manufacturer. The Samtec SHF-104-01-L-D-SM remains in active production and is the recommended substitute for ongoing procurement and system support.
