DT04-4P-LE11 Equivalent & Substitute Parts
Part Overview
The DT04-4P-LE11 is a 4-position rectangular connector receptacle housing manufactured by TE Connectivity Deutsch Connectors. This panel-mount receptacle is designed for applications requiring sealed, latch-secured connections with crimp termination. The connector operates across an industrial temperature range of -55°C to 125°C and meets IP68 and IP6K9K ingress protection ratings. The part is actively produced and ROHS3 compliant, making it suitable for current procurement cycles. Substitute parts are identified when original inventory is unavailable, when supply chain constraints occur, or when design flexibility permits cross-manufacturer qualification.

Substitute Part Grouping Explanation
Substitution eligibility for the DT04-4P-LE11 is determined by strict alignment of the following parameters:
Critical Matching Parameters:
- Connector type (Receptacle)
- Number of positions (4)
- Number of rows (2)
- Contact type (Male Pin)
- Mounting type (Panel Mount)
- Contact termination method (Crimp)
- Fastening type (Latch Holder)
- Operating temperature range (-55°C to 125°C minimum)
- Color (Black)
- RoHS compliance status (ROHS3 Compliant)
The AT04-4P-LE11 manufactured by Amphenol Sine Systems Corp satisfies all critical matching parameters. Both connectors are active products with identical electrical and mechanical interface specifications, enabling direct substitution in applications where cross-manufacturer qualification is permitted.

Engineering Selection Recommendations
Both the DT04-4P-LE11 and AT04-4P-LE11 are active products with current manufacturing status and full ROHS3 compliance. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.
The DT04-4P-LE11 (TE Connectivity Deutsch Connectors) is the primary specification. Current inventory reports 726 pieces in stock.
The AT04-4P-LE11 (Amphenol Sine Systems Corp) is a qualified substitute with 836 pieces in stock. This part is suitable for direct replacement when TE Connectivity inventory is constrained or when cross-manufacturer sourcing is permitted by design documentation.
Both connectors meet identical electrical and mechanical interface requirements. Selection should be based on procurement lead time, cost structure, and existing supply chain relationships.
Frequently Asked Questions (FAQ)
Q: Can the AT04-4P-LE11 be used as a direct replacement for the DT04-4P-LE11?
A: Yes. Both connectors share identical specifications for connector type, position count, row configuration, contact type, mounting method, termination type, fastening mechanism, operating temperature range, and compliance status. Direct substitution is permissible when cross-manufacturer qualification is approved.
Q: Are the contacts included with these connector housings?
A: No. Both the DT04-4P-LE11 and AT04-4P-LE11 are supplied as housings only. Contacts must be procured separately and are not included in the package.
Q: What is the difference in insulation material between these two parts?
A: The DT04-4P-LE11 uses Polyamide (PA) Nylon with glass filling. The AT04-4P-LE11 uses Thermoplastic material. Both materials meet the operating temperature range and environmental protection requirements specified for these connectors.
Q: Do these connectors have different moisture sensitivity levels?
A: The DT04-4P-LE11 has MSL listed as Not Applicable. The AT04-4P-LE11 has MSL 1 (Unlimited). This difference does not affect substitution eligibility for sealed connector applications.
Q: What ingress protection ratings does the DT04-4P-LE11 provide?
A: The DT04-4P-LE11 meets IP68 and IP6K9K ratings, providing sealed protection against dust and high-pressure water jets. The AT04-4P-LE11 is specified as sealed, meeting equivalent environmental protection requirements.
Q: Are both parts available in current inventory?
A: Yes. The DT04-4P-LE11 has 726 pieces in stock. The AT04-4P-LE11 has 836 pieces in stock. Both are listed as new original inventory.
