Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNC Tech 3210-24-003-11-00 is determined by the following critical parameters:

• Connector configuration: 24-position, 2-row header with 1.27mm pitch
• Mounting method: Surface mount technology
• Termination type: Solder connection
• Fastening mechanism: Push-pull engagement
• Contact gender: Male pins
• Mating contact finish: Gold plating
• Environmental compliance: ROHS3 compliance and MSL 1 rating

The Samtec Inc. ESHF-112-01-L-D-SM satisfies all critical substitution parameters. Both connectors share identical pitch, position count, row configuration, mounting type, termination method, and fastening type. Both maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings, ensuring compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The Samtec part offers extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C) and active product status, providing improved long-term availability and supply chain continuity. The connector is available in tube packaging with 783 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Are the CNC Tech 3210-24-003-11-00 and Samtec ESHF-112-01-L-D-SM mechanically interchangeable?

A: Yes. Both connectors share identical pitch (1.27mm), position count (24), row configuration (2 rows), and row spacing (1.27mm). Both use surface mount solder termination with push-pull fastening, ensuring mechanical compatibility in equivalent board layouts.

Q: What are the key differences between these connectors?

A: The Samtec part features shrouded 4-wall construction compared to the CNC Tech 2-wall design. The Samtec connector also specifies contact length (0.120"), insulation height (0.215"), and extended operating temperature range (-55°C ~ 125°C). The Samtec part uses phosphor bronze contacts with tin finish on posts, while the CNC Tech part uses brass contacts.

Q: Does the Samtec substitute maintain compliance certifications?

A: Yes. The Samtec ESHF-112-01-L-D-SM is ROHS3 compliant with MSL 1 moisture sensitivity rating, matching the compliance profile of the CNC Tech connector.

Q: What packaging is available for the substitute part?

A: The Samtec ESHF-112-01-L-D-SM is supplied in tube packaging with 783 units currently in inventory.

Q: Are there any thermal performance differences?

A: The Samtec connector operates across a wider temperature range (-55°C ~ 125°C) compared to the CNC Tech part (-40°C ~ 105°C), providing greater thermal margin for extended operating environments.
