Substitute Part Grouping Explanation

Substitute parts for the AT06-4S are grouped into two categories based on allowed electrical and mechanical parameters:

Parametric Equivalents (Amphenol Sine Systems Corp AT Series™): Parts AT06-4S-BLU, AT06-4S-BRN, AT06-4S-GRN, AT06-4S-ORG, and AT06-4S-YEL are direct parametric equivalents that maintain identical electrical and mechanical specifications. These parts differ only in housing color, which serves as a visual identification mechanism in circuit design and system integration. All parametric equivalents share the same base product number (AT06-4S), connector type, contact configuration, termination method, fastening mechanism, operating temperature range, and compliance certifications. Color variation does not affect functional compatibility or electrical performance.

Direct Manufacturer Equivalent (TE Connectivity Deutsch Connectors): Part DT06-4S represents a direct manufacturer equivalent from TE Connectivity. While manufactured by a different supplier, this part maintains the same electrical and mechanical interface specifications, including 4-position configuration, female socket contacts, crimp termination, latch lock fastening, and identical operating temperature range. The DT06-4S features enhanced sealing specifications (IP68, IP6K9K) and utilizes polyamide insulation material instead of thermoplastic, representing a higher-performance alternative within the same connector family.

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance with REACH unaffected designation, ensuring regulatory compliance across industrial and commercial applications.

Amphenol AT Series™ Color Variants (AT06-4S-BLU, AT06-4S-BRN, AT06-4S-GRN, AT06-4S-ORG, AT06-4S-RED, AT06-4S-YEL): These parts are functionally identical to the AT06-4S and differ only in housing color. Selection among these variants is determined by circuit identification requirements, color-coding standards, or system integration specifications. All variants maintain identical electrical performance, mechanical interface, and environmental specifications. Packaging format varies between bulk (AT06-4S) and box configurations for the color variants.

TE Connectivity DT06-4S: This part represents an alternative manufacturer solution with enhanced environmental sealing specifications (IP68, IP6K9K ratings). The DT06-4S utilizes polyamide insulation material (PA66, Nylon 6/6, Glass Filled) compared to the thermoplastic insulation of AT Series parts. This alternative is suitable for applications requiring higher ingress protection ratings or where polyamide material specifications are mandated. The DT06-4S maintains identical electrical interface and operating temperature range, ensuring direct functional compatibility.

Selection between Amphenol and TE Connectivity options depends on specific environmental protection requirements and material specifications. Both manufacturers' products are in active production with equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can AT06-4S color variants be used interchangeably with the standard AT06-4S?

A: Yes. All AT Series™ color variants (AT06-4S-BLU, AT06-4S-BRN, AT06-4S-GRN, AT06-4S-ORG, AT06-4S-RED, AT06-4S-YEL) are functionally identical to the AT06-4S. Color differences serve only as visual identification markers and do not affect electrical performance, mechanical compatibility, or environmental specifications. Selection is based on circuit identification requirements or system color-coding standards.

Q: Is the DT06-4S from TE Connectivity a direct replacement for the AT06-4S?

A: The DT06-4S maintains identical electrical and mechanical interface specifications, including 4-position configuration, female socket contacts, crimp termination, and latch lock fastening. However, the DT06-4S features enhanced environmental sealing (IP68, IP6K9K) and polyamide insulation material. These differences represent performance enhancements rather than incompatibilities. The DT06-4S is suitable for applications requiring higher ingress protection ratings.

Q: What is the difference between bulk and box packaging for AT Series connectors?

A: Packaging format does not affect connector specifications or performance. The AT06-4S is supplied in bulk packaging, while color variants are supplied in box packaging. Packaging selection is determined by inventory management requirements, order quantities, and supply chain logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed, including AT Series™ color variants and the TE Connectivity DT06-4S, maintain ROHS3 compliance and REACH unaffected status. All parts are suitable for applications subject to environmental and regulatory compliance requirements.

Q: What operating temperature range applies to all substitute parts?

A: All substitute parts operate across the identical temperature range of -55°C to 125°C. This specification is maintained across all Amphenol AT Series™ variants and the TE Connectivity DT06-4S, ensuring thermal compatibility in equivalent applications.

Q: Can contacts from one manufacturer be used with housings from another manufacturer?

A: Contact compatibility between manufacturers is determined by contact specifications and interface geometry. The provided data indicates that contacts are not included with any housing part. Contact selection and compatibility must be verified against specific contact part numbers and manufacturer interface specifications.

Q: What does the "Contacts Not Included" note mean?

A: This designation indicates that the part number references only the connector housing assembly. Crimp contacts must be ordered separately and installed into the housing. Contact part numbers and specifications are determined by wire gauge requirements (14-20 AWG for AT06-4S) and must be selected from the same manufacturer series to ensure proper fit and electrical performance.
