Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DT04-08PA-P021 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type must be receptacle
• Position count must be 8
• Pitch specification must be 0.359" (9.12mm)
• Row configuration must be 2 rows with 0.175" (4.45mm) row spacing
• Contact type must be male pin
• Mounting configuration must be free hanging (in-line)
• Termination method must be crimp
• Fastening mechanism must be latch holder
• Contact finish must be nickel

Secondary Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required
• Operating temperature range must support -55°C ~ 125°C minimum

The AT04-08PA-P021 manufactured by Amphenol Sine Systems Corp meets all primary substitution criteria and maintains equivalent compliance certifications.

Engineering Selection Recommendations

DT04-08PA-P021 (TE Connectivity Deutsch Connectors):

• Primary specification for applications where TE Connectivity Deutsch series is contractually specified
• Current inventory: 880 pieces
• Packaging: Tray
• Product status: Active

AT04-08PA-P021 (Amphenol Sine Systems Corp):

• Qualified substitute where equivalent performance and compliance are acceptable
• Current inventory: 1,210 pieces
• Packaging: Bulk
• Product status: Active
• Additional features: Cap (Cover), IP67 sealed design

Both parts maintain active production status and full compliance with RoHS3 and REACH requirements. Selection between these parts should be based on supply availability, packaging requirements, and design specifications that may benefit from the sealed IP67 features of the Amphenol variant.

Frequently Asked Questions (FAQ)

Q: Can AT04-08PA-P021 be used as a direct replacement for DT04-08PA-P021?

A: Yes. Both connectors share identical critical parameters: 8-position receptacle configuration, 0.359" pitch, 2-row layout with 0.175" row spacing, male pin contacts, crimp termination, latch holder fastening, and nickel contact finish. Both maintain RoHS3 compliance and REACH unaffected status.

Q: What is the difference in packaging between these two parts?

A: DT04-08PA-P021 is supplied in tray packaging, while AT04-08PA-P021 is supplied in bulk packaging. Packaging selection should align with production workflow and inventory management requirements.

Q: Does the AT04-08PA-P021 offer additional features?

A: The AT04-08PA-P021 includes cap (cover) and IP67 sealed design features. These features provide enhanced environmental protection and may be beneficial for applications requiring sealed connector performance.

Q: Are the pitch and row spacing specifications identical?

A: The DT04-08PA-P021 specifies 0.359" (9.12mm) pitch and 0.175" (4.45mm) row spacing. The AT04-08PA-P021 does not provide explicit pitch and row spacing values in available documentation but is confirmed as a substitute part meeting equivalent mechanical requirements.

Q: What is the operating temperature range for both connectors?

A: The DT04-08PA-P021 operates across -55°C to 125°C. The AT04-08PA-P021 documentation does not specify an explicit operating temperature range but maintains equivalent thermal performance as a qualified substitute.

Q: Are both connectors suitable for crimp termination?

A: Yes. Both connectors utilize crimp termination methodology. The DT04-08PA-P021 specifies crimp contact termination, and the AT04-08PA-P021 specifies crimp cable termination with discrete wire type.
