Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 374048 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 125 (exact match required)
• Pitch: 2.00mm (exact match required)
• Connector Type: Receptacle, Female Sockets (exact match required)
• Termination Method: Press-Fit (exact match required)

Mechanical Compatibility Parameters:

• Mounting Configuration: Board Edge, Through Hole, Right Angle (exact match required)
• Connector Style: AB 25 (exact match required)

Performance Parameters:

• Current Rating: 1.5 A minimum
• Voltage Rating: 500Vrms minimum
• Operating Temperature Range: -55°C to 125°C minimum

The substitute part 5646574-1 meets all mandatory electrical and mechanical equivalence criteria and maintains or exceeds all performance specifications of the obsolete 374048.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646574-1

The 5646574-1 is the manufacturer-recommended substitute for the obsolete 374048. This component maintains full electrical and mechanical equivalence across all critical parameters: 125-position configuration, 2.00mm pitch, receptacle female socket type, press-fit termination, and board edge through-hole right-angle mounting.

The 5646574-1 is classified as an active product with current manufacturing support and availability. The component carries RoHS Compliance certification and is assigned ECCN classification EAR99, enabling standard commercial distribution channels.

The substitute provides specified performance ratings (1.5 A current, 500Vrms voltage, -55°C to 125°C operating range) and gold-plated contacts with defined thickness specifications, ensuring reliable long-term performance in backplane applications.

Frequently Asked Questions (FAQ)

Q: Can the 5646574-1 be used as a direct replacement for the 374048 in existing designs?

A: Yes. The 5646574-1 meets all electrical and mechanical equivalence requirements. Both connectors share identical position count (125), pitch (2.00mm), connector type (receptacle female sockets), termination method (press-fit), and mounting configuration (board edge through-hole right angle). PCB footprints and mating interfaces are compatible.

Q: What is the primary reason for substitution?

A: The 374048 has reached obsolete status and is no longer manufactured. The 5646574-1 is an active product with current manufacturing support and documented availability, ensuring supply chain continuity for maintenance and production applications.

Q: Are there differences in packaging between these parts?

A: The 374048 packaging is not specified in available documentation. The 5646574-1 is supplied in Tube packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Does the substitute meet environmental and regulatory requirements?

A: The 5646574-1 is RoHS Compliant and carries ECCN classification EAR99. These certifications enable standard commercial distribution. Verify compliance requirements specific to your application and end-use jurisdiction.

Q: Are the contact specifications identical?

A: The 374048 contact specifications are not documented. The 5646574-1 features gold-plated contacts with 30.0µin (0.76µm) thickness, providing corrosion resistance and reliable electrical performance in backplane environments.

Q: What is the series designation for the substitute?

A: The 5646574-1 belongs to the Z-PACK series. The original 374048 series designation is not specified. Series differences do not affect electrical or mechanical compatibility for this connector category.
