DT04-12PA-P031 Equivalent & Substitute Parts

Part Overview

The DT04-12PA-P031 is a 12-position rectangular receptacle connector housing manufactured by TE Connectivity Deutsch Connectors. This connector is designed for free-hanging, in-line applications with crimp termination and latch holder fastening. The housing is gray plastic with IP68 and IP6K9K protection ratings, suitable for operating temperatures from -55°C to 125°C. The product is active and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the primary part is unavailable or when alternative sourcing is necessary.

Engineering Selection Recommendations

Both the DT04-12PA-P031 and AT04-12PA-P031 are active products with ROHS3 compliance and EAR99 export classification. Selection between these rectangular connectors should be based on:

Product Availability: The AT04-12PA-P031 has 1309 units in stock compared to 837 units for the DT04-12PA-P031, providing greater availability for immediate procurement.

Regulatory Compliance: Both parts meet ROHS3 requirements and share identical ECCN and HTSUS classifications, ensuring equivalent regulatory standing for applications requiring compliance documentation.

Moisture Sensitivity: The AT04-12PA-P031 carries MSL 1 (Unlimited) rating, while the DT04-12PA-P031 lists MSL as Not Applicable. This distinction does not affect substitution eligibility but should be noted for storage and handling protocols.

Protection Features: The DT04-12PA-P031 provides IP68 and IP6K9K ratings. The AT04-12PA-P031 provides IP67 protection with cap (cover) inclusion. Environmental protection requirements should guide final selection.

Frequently Asked Questions (FAQ)

Q: Can the AT04-12PA-P031 directly replace the DT04-12PA-P031 in existing applications?

A: Yes. Both connectors share identical electrical and mechanical specifications including 12-position, 2-row configuration, crimp termination, latch holder fastening, and gray plastic housing. Both operate across -55°C to 125°C and meet ROHS3 compliance.

Q: What are the differences between these two rectangular connectors?

A: The primary differences are manufacturer (TE Connectivity versus Amphenol Sine Systems), contact finish (not specified for DT04-12PA-P031 versus gold for AT04-12PA-P031), protection ratings (IP68/IP6K9K versus IP67 with cap), and moisture sensitivity level classification. Electrical and mechanical form factors are equivalent.

Q: Are there any compatibility concerns when substituting the AT04-12PA-P031 for the DT04-12PA-P031?

A: No compatibility concerns exist for the specified parameters. Both connectors accommodate male pin contacts, use crimp termination, and employ identical latch holder fastening mechanisms. Mating interfaces are equivalent.

Q: What is the significance of the MSL rating difference?

A: The AT04-12PA-P031 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The DT04-12PA-P031 lists MSL as Not Applicable. This affects storage protocols but does not impact functional substitution.

Q: How do the protection ratings affect substitution decisions?

A: The DT04-12PA-P031 provides IP68 and IP6K9K protection, while the AT04-12PA-P031 provides IP67 protection with included cap. Applications requiring IP68 or IP6K9K ratings should retain the DT04-12PA-P031. Applications requiring IP67 or lower can use the AT04-12PA-P031.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the DT04-12PA-P031 and AT04-12PA-P031 operate across -55°C to 125°C, making them functionally equivalent for temperature-dependent applications.

Q: What packaging format is available for both parts?

A: Both connectors are supplied in bulk packaging, suitable for production assembly and integration into larger systems.
