Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-2600031-0 connector housing is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 4
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Operating Temperature Range: -55°C ~ 125°C
• RoHS3 Compliance

Acceptable Variation Parameters:

• Series designation (DT-XT to DT)
• Housing color (Black to Gray)
• Insulation material formulation (PA to PA66)
• Pitch specification (when not explicitly defined in substitute)
• Enhanced sealing features (IP68, IP6K9K)

The substitute part DT06-4S meets all mandatory matching criteria while offering improved environmental sealing characteristics and active product status, making it a direct functional equivalent for the obsolete 1-2600031-0.

Parameter Comparison

Engineering Selection Recommendations

The DT06-4S connector housing serves as the direct substitute for the obsolete 1-2600031-0 based on the following engineering criteria:

Functional Equivalence: All critical electrical and mechanical parameters align between the main part and substitute. Both connectors accommodate 4-position, 2-row configurations with identical contact types, termination methods, and fastening mechanisms.

Compliance Alignment: Both parts maintain ROHS3 compliance, ensuring regulatory consistency in applications requiring restricted substance adherence. The substitute part carries REACH Unaffected status, providing additional regulatory clarity.

Product Status Advantage: The DT06-4S holds Active product status, ensuring long-term availability and supply chain stability compared to the Obsolete 1-2600031-0. This transition eliminates future obsolescence risk.

Environmental Performance Enhancement: The DT06-4S incorporates IP68 and IP6K9K sealing ratings, providing superior environmental protection compared to the standard sealed design of the original part. This enhancement maintains backward compatibility while offering improved durability in demanding applications.

Material Specification: The PA66 (Nylon 6/6) formulation in the DT06-4S represents a refined polyamide specification compared to the general PA designation in the 1-2600031-0, maintaining mechanical and thermal performance across the identical operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the DT06-4S directly replace the 1-2600031-0 in existing assemblies?

A: Yes. The DT06-4S meets all mandatory functional parameters: 4-position plug housing with female socket contacts, 2-row configuration, crimp termination, latch lock fastening, and identical operating temperature range (-55°C to 125°C). Both parts are RoHS3 compliant.

Q: What is the significance of the color difference between the two parts?

A: The color variation (Black to Gray) is a cosmetic difference that does not affect electrical or mechanical function. Color selection depends on application-specific requirements or assembly identification schemes. The housing material composition and performance characteristics remain equivalent.

Q: Does the DT06-4S provide any functional improvements over the 1-2600031-0?

A: The DT06-4S incorporates IP68 and IP6K9K environmental sealing ratings, providing enhanced protection against moisture and high-pressure water jets compared to the standard sealed design of the original part. This represents an improvement in environmental durability while maintaining full backward compatibility.

Q: Are the contact specifications identical between these two parts?

A: Both parts specify Female Socket contact type with crimp termination. The 1-2600031-0 documentation notes that contacts are not included; the same applies to the DT06-4S. Contact compatibility depends on the specific contact part numbers used in your assembly, which must be verified separately.

Q: What is the pitch specification for the DT06-4S?

A: The DT06-4S pitch specification is not explicitly defined in the available documentation. The 1-2600031-0 specifies 0.177" (4.50mm) pitch. For applications requiring confirmed pitch alignment, contact the manufacturer or consult detailed mechanical drawings for the DT06-4S.

Q: Is the DT06-4S available in the same packaging as the 1-2600031-0?

A: The DT06-4S is supplied in Bulk packaging, whereas the 1-2600031-0 packaging specification is not defined in the available data. Packaging format does not affect connector function or compatibility; it relates only to order quantity and handling requirements.

Q: What is the difference between the DT-XT and DT series designations?

A: The DT-XT series (1-2600031-0) and DT series (DT06-4S) represent different product generations within the TE Connectivity Deutsch Connectors portfolio. The DT series represents the current active product line, while DT-XT is obsolete. Both series maintain compatible connector specifications for the 4-position housing configuration.
