AT04-3P-SB01 Equivalent & Substitute Parts

Part Overview

The AT04-3P-SB01 is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp, part of the AT Series™ product line. This component serves as the housing for receptacle connectors in applications requiring reliable electrical connections across industrial and commercial environments. The part is currently in active production status with 871 pieces available in new original inventory.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, when supply chain optimization is required, or when design flexibility permits the use of equivalent components that meet the same functional and electrical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-3P-SB01 is determined by the following critical parameters:

Primary Substitution Criteria:

• Connector type must be receptacle
• Contact type must be male pin
• Number of positions must be 3
• Operating temperature range must encompass -55°C ~ 125°C
• RoHS3 compliance required
• REACH unaffected status required

The substitute part DT04-3P-E008 meets these core functional requirements. While differences exist in secondary parameters such as number of rows, insulation material composition, and additional features, these variations do not prevent functional equivalence when the primary electrical and mechanical interface requirements are satisfied.

Engineering Selection Recommendations

AT04-3P-SB01 Selection Criteria:

• Primary choice when Amphenol Sine Systems Corp sourcing is specified
• Preferred when single-row configuration is required
• Thermoplastic insulation material is specified requirement
• MSL 1 (Unlimited) moisture sensitivity is required

DT04-3P-E008 Selection Criteria:

• Alternative source when AT04-3P-SB01 availability is constrained
• Suitable when two-row configuration is acceptable
• Glass-filled polyamide insulation material meets or exceeds performance requirements
• Enhanced environmental protection features (IP68, IP6K9K) provide additional capability
• Both parts maintain identical operating temperature range and compliance certifications

Both parts are active production items with established supply chains. Selection between these parts should be based on design specification requirements for row configuration and insulation material composition, as well as availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can DT04-3P-E008 directly replace AT04-3P-SB01 in all applications?

A: Both parts share identical core specifications: 3-position receptacle housing with male pin contacts, -55°C ~ 125°C operating temperature, ROHS3 compliance, and REACH unaffected status. The primary difference is the number of rows (1 versus 2) and insulation material composition. Substitution is valid when the application design permits a two-row configuration and glass-filled polyamide insulation material.

Q: What is the significance of the row configuration difference?

A: The AT04-3P-SB01 features a single-row arrangement, while the DT04-3P-E008 features a two-row arrangement. This affects the physical footprint and mounting profile of the connector housing. Applications with space constraints or specific PCB layout requirements may require the single-row configuration.

Q: Are the insulation materials functionally equivalent?

A: The AT04-3P-SB01 uses thermoplastic insulation, while the DT04-3P-E008 uses glass-filled polyamide (PA) nylon. Glass-filled polyamide provides enhanced mechanical strength and thermal stability. Both materials are suitable for the specified operating temperature range of -55°C ~ 125°C.

Q: Do both parts require separate contact procurement?

A: Yes. Both the AT04-3P-SB01 and DT04-3P-E008 are connector housings supplied without contacts included. Contacts must be procured separately and are compatible with the respective connector series.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. These certifications ensure compliance with environmental and hazardous substance regulations applicable to electronic components in regulated markets.

Q: How do the packaging formats differ?

A: The AT04-3P-SB01 packaging format is not specified in available data. The DT04-3P-E008 is supplied in bulk packaging. Packaging format may affect ordering quantities and handling procedures.
