DT04-3P-LE12 Equivalent & Substitute Parts

Part Overview

The DT04-3P-LE12 is a 3-position rectangular connector receptacle housing manufactured by TE Connectivity Deutsch Connectors. This panel-mount receptacle is designed for applications requiring sealed, latched connections with crimp-style termination. The connector operates across an extended temperature range of -55°C to 125°C and meets IP68 and IP6K9K ingress protection ratings.

Substitute parts are identified when equivalent rectangular connectors share identical functional parameters: connector type (receptacle), contact type (male pin), number of positions (3), mounting configuration (panel mount), termination method (crimp), fastening mechanism (latch holder), and operating temperature range. Product availability, manufacturing source, and design variations may necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DT04-3P-LE12 are identified based on strict equivalence across the following critical parameters:

Electrical Compatibility:

• Connector type: Receptacle housing
• Contact type: Male pin configuration
• Number of positions: 3-position
• Contact termination: Crimp attachment method

Mechanical Compatibility:

• Mounting configuration: Panel mount with flange
• Fastening mechanism: Latch holder
• Number of rows: 2-row arrangement
• Color specification: Black

Environmental & Compliance:

• Operating temperature range: -55°C to 125°C
• RoHS3 compliance status
• MSL rating: 1 (Unlimited)

The AT04-3P-LE12 manufactured by Amphenol Sine Systems Corp satisfies all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the DT04-3P-LE12 and AT04-3P-LE12 are active product status components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by:

Availability and Inventory: Current stock levels and lead times from respective manufacturers and distributors.

Compliance Requirements: Both parts meet identical regulatory standards (RoHS3, REACH unaffected, EAR99 ECCN classification).

Insulation Material Specification: The DT04-3P-LE12 specifies polyamide (PA66) nylon 6/6 glass-filled insulation, while the AT04-3P-LE12 specifies thermoplastic insulation. Material selection depends on application-specific thermal and chemical resistance requirements within the stated operating temperature range.

Feature Set: The AT04-3P-LE12 includes a cap (cover) feature in addition to the mounting flange and sealed design present in both parts. The DT04-3P-LE12 includes IP68 and IP6K9K ingress protection ratings.

Termination Compatibility: Both parts require crimp-style contacts (not included with housing). Ensure contact specifications match the selected housing base product number (DT04 or AT04-3P).

Frequently Asked Questions (FAQ)

Q: Can the AT04-3P-LE12 directly replace the DT04-3P-LE12 in existing assemblies?

A: Direct replacement is possible when the application requirements align with both parts' specifications. Both housings accept 3-position male pin crimp contacts, feature identical mounting configurations (panel mount with latch holder fastening), and operate across the same temperature range (-55°C to 125°C). Verify that the specific contact part numbers are compatible with both the DT04 and AT04-3P base product numbers.

Q: What is the significance of the insulation material difference between these parts?

A: The DT04-3P-LE12 uses polyamide (PA66) nylon 6/6 glass-filled material, while the AT04-3P-LE12 uses thermoplastic insulation. Both materials support the stated operating temperature range and MSL rating. Material selection should be based on application-specific requirements for chemical resistance, mechanical strength, and thermal stability within the -55°C to 125°C operating window.

Q: Are contacts included with these housings?

A: No. Both the DT04-3P-LE12 and AT04-3P-LE12 are receptacle housings only. Contacts must be sourced separately and selected according to the base product number (DT04 or AT04-3P) and the required crimp termination specifications.

Q: What is the difference between IP68 and IP6K9K ratings mentioned for the DT04-3P-LE12?

A: IP68 indicates protection against dust ingress and temporary immersion in water. IP6K9K indicates protection against high-pressure water jets. Both ratings are environmental sealing specifications. The AT04-3P-LE12 is specified as sealed without explicit IP rating notation in the provided parameters.

Q: Do both parts have identical RoHS and REACH compliance status?

A: Yes. Both the DT04-3P-LE12 and AT04-3P-LE12 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification. Compliance status is equivalent for regulatory purposes.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL (Moisture Sensitivity Level) 1 indicates the lowest moisture sensitivity classification. These parts have unlimited shelf life under normal storage conditions and do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: Can these 3-position housings be used in applications requiring different position counts?

A: No. Both the DT04-3P-LE12 and AT04-3P-LE12 are fixed 3-position housings. Applications requiring different position counts require alternative part numbers from the DT or AT series with different position designations.
