AT04-08PC Equivalent & Substitute Parts Reference

Part Overview

The AT04-08PC is an 8-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component serves as the housing element in the AT Series™ connector family, designed for applications requiring crimp-terminated connections with latch holder fastening. The part is classified as Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent connectors share identical functional parameters: 8-position configuration, receptacle type with male pin contacts, 2-row arrangement, crimp termination, latch holder fastening, green color, and matching operating temperature range of -55°C to 125°C. Substitutes become necessary when primary part availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer qualification.

Substitute Part Grouping Explanation

Substitution logic for the AT04-08PC is based on strict equivalence across all critical functional parameters. The following parameters must match identically for a part to qualify as a direct substitute:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 8
• Contact Type: Male Pin
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant
• Contact Inclusion: Contacts Not Included (housing only)

Secondary Compatibility Parameters:

• Color: Green (visual consistency)
• Insulation Material: Thermoplastic or Plastic (functionally equivalent)

The DT04-08PC from TE Connectivity Deutsch Connectors satisfies all critical parameters and qualifies as a direct substitute. Both parts are Active status products with identical electrical and mechanical specifications within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

AT04-08PC Selection Criteria:

• Primary choice when Amphenol Sine Systems Corp supply chain is confirmed available
• Preferred for existing designs already qualified to AT Series™ connector family
• Current inventory: 1307 pieces in stock
• MSL 1 rating provides unlimited shelf life storage capability

DT04-08PC Selection Criteria:

• Direct substitute when AT04-08PC availability is constrained
• Suitable for new designs requiring cross-manufacturer flexibility
• Current inventory: 1585 pieces in stock
• Both parts maintain identical electrical performance and environmental specifications
• Both parts satisfy ROHS3 and REACH compliance requirements
• Both parts carry EAR99 export classification

Compliance Verification: Both parts are Active status products with full ROHS3 compliance and REACH Unaffected status. Export classification (EAR99) is identical for both manufacturers. Selection between these parts is determined by supply availability and design qualification status rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can DT04-08PC directly replace AT04-08PC in existing assemblies?

A: Yes. Both parts are 8-position receptacle housings with identical connector type, contact configuration, mounting method, termination type, and fastening mechanism. The parts share matching operating temperature ranges (-55°C to 125°C) and equivalent insulation materials. Substitution is valid at the housing level; however, contact compatibility with existing mated plugs must be verified through the respective connector series specifications.

Q: What is the significance of "Contacts Not Included" in both part specifications?

A: Both AT04-08PC and DT04-08PC are housing-only components. Crimp contacts must be sourced separately and are not supplied with these housings. Contact selection must match the wire gauge specification (14-20 AWG for AT04-08PC) and the respective manufacturer's contact compatibility matrix.

Q: Are there differences in insulation material between the two parts?

A: AT04-08PC specifies Thermoplastic insulation, while DT04-08PC specifies Plastic insulation. Both materials are functionally equivalent for the operating temperature range (-55°C to 125°C) and environmental conditions specified. Material selection does not affect electrical performance or mechanical compatibility.

Q: Do both parts have identical moisture sensitivity ratings?

A: No. AT04-08PC carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. DT04-08PC lists MSL as Not Applicable, which is consistent with plastic housing components that do not absorb moisture. Both ratings indicate unrestricted shelf life storage.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: connector type (Receptacle), position count (8), contact type (Male Pin), row configuration (2 rows), mounting method (Free Hanging In-Line), termination type (Crimp), fastening mechanism (Latch Holder), operating temperature range (-55°C to 125°C), and regulatory compliance (ROHS3 Compliant, REACH Unaffected). All these parameters are identical between AT04-08PC and DT04-08PC.

Q: Can these housings be used interchangeably with different contact types?

A: No. These housings are designed specifically for crimp-terminated male pin contacts. The housing geometry and contact retention mechanism are optimized for this configuration. Contact type substitution is not permitted.

Q: What is the significance of the "Latch Holder" fastening type?

A: Latch Holder fastening provides positive mechanical retention between the plug and receptacle. This mechanism ensures secure mating and prevents accidental disconnection. Both AT04-08PC and DT04-08PC employ identical latch holder fastening, ensuring compatible mating performance.
