Substitute Part Grouping Explanation

The DT04-12PA-C017 manufactured by TE Connectivity Deutsch Connectors qualifies as a direct substitute for the AT04-12PA-SS01 based on the following critical parameters:

Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 12
• Number of Rows: 2
• Contact Type: Male Pin
• Contact Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Holder
• Color: Gray
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The substitute part maintains electrical and mechanical compatibility through identical position count, row configuration, contact type, and termination method. Both parts operate within the same temperature range and meet the same regulatory compliance standards. The substitute part is available in box packaging with higher current inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-12PA-SS01 and DT04-12PA-C017 are Active status products with ROHS3 compliance and REACH Unaffected status, qualifying them for current production use. The selection between these parts should be based on:

Availability: The DT04-12PA-C017 substitute offers higher inventory availability (1216 pieces versus 1070 pieces), providing supply chain flexibility.

Packaging Format: The main part is supplied in bulk packaging, while the substitute is supplied in box packaging. Packaging selection depends on assembly line requirements and inventory management protocols.

Material Composition: The main part uses thermoplastic insulation material, while the substitute uses polyamide (PA) nylon with glass filling. Both materials support the identical operating temperature range and regulatory compliance requirements.

Regulatory Compliance: Both parts meet ROHS3 compliance and REACH Unaffected status, ensuring equivalent environmental and regulatory standing for production applications.

Frequently Asked Questions (FAQ)

Q: Can the DT04-12PA-C017 be used as a direct replacement for the AT04-12PA-SS01?

A: Yes. Both parts share identical electrical and mechanical specifications including 12-position configuration, 2-row layout, male pin contact type, crimp termination, free-hanging mounting, and latch holder fastening. Operating temperature ranges and regulatory compliance are equivalent.

Q: What are the key compatibility factors for these rectangular connectors?

A: The critical compatibility parameters are connector type (receptacle), position count (12), row configuration (2), contact type (male pin), termination method (crimp), mounting style (free-hanging in-line), and fastening mechanism (latch holder). These parameters determine mechanical and electrical interchangeability.

Q: Are there differences in insulation material between these parts?

A: Yes. The AT04-12PA-SS01 uses thermoplastic insulation, while the DT04-12PA-C017 uses polyamide (PA) nylon with glass filling. Both materials support the operating temperature range of -55°C to 125°C and meet all specified compliance requirements.

Q: Does packaging format affect connector performance?

A: No. Packaging format (bulk versus box) does not affect connector electrical or mechanical performance. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Are both parts suitable for new production designs?

A: Yes. Both parts maintain Active product status and ROHS3 compliance, qualifying them for current production applications and new design implementations.

Q: What is the pitch specification for these connectors?

A: The AT04-12PA-SS01 does not specify pitch in the provided parameters. The DT04-12PA-C017 specifies a pitch of 0.359" (9.12mm). Pitch information should be confirmed with connector contact specifications for complete assembly compatibility.
