Substitute Part Grouping Explanation

The substitute part TE Connectivity AMP Connectors 2347091-1 is identified as a direct equivalent based on the following critical parameters that determine substitution validity:

Matching Parameters:

• Number of Positions: 56 (identical)
• Pitch: 0.079" (2.00mm) (identical)
• Connector Type: Header, Male Pins (identical)
• Mounting Type: Through Hole (identical)
• Current Rating: 1.5 A (identical)
• Voltage Rating: 500VAC (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Termination Method: Press-Fit (compatible with Through Hole mounting)

The substitute part 2347091-1 maintains all critical electrical and mechanical parameters required for functional equivalence. The transition from the obsolete Erni series to the active TE Connectivity AMP Connectors Z-PACK series ensures continued availability and compliance with current manufacturing standards.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The TE Connectivity AMP Connectors 2347091-1 is the designated active substitute for the obsolete 204976. This part maintains electrical and mechanical compatibility while providing:

• Active Product Status: Ensures long-term availability and continued manufacturing support
• ROHS3 Compliance: Meets current environmental and regulatory requirements
• Defined Specifications: Gold contact finish and Press-Fit termination provide enhanced reliability documentation
• Standard Packaging: Tube packaging facilitates integration into modern manufacturing workflows

For Legacy System Maintenance: Existing inventory of 204976 (18,905 units) remains available for direct replacement in established applications. However, transition to 2347091-1 is recommended for new production runs and system redesigns to eliminate future obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Are the 204976 and 2347091-1 mechanically interchangeable?

A: Yes. Both connectors feature 56 positions at 0.079" (2.00mm) pitch with Through Hole mounting. The 7-row configuration of 2347091-1 accommodates the 56-position requirement identically to the original design.

Q: What is the difference in contact finish between these parts?

A: The substitute part 2347091-1 specifies Gold contact finish, which is not documented for the obsolete 204976. Gold plating enhances corrosion resistance and electrical conductivity, providing improved long-term reliability.

Q: Does the Press-Fit termination of 2347091-1 differ from the original 204976?

A: The termination method for 204976 is not specified in available documentation. Press-Fit termination in 2347091-1 is a standard Through Hole mounting technique compatible with PCB assembly processes.

Q: Is 2347091-1 RoHS compliant?

A: Yes. The 2347091-1 is ROHS3 Compliant, meeting current environmental regulations. RoHS compliance status for the obsolete 204976 is not documented.

Q: What is the Moisture Sensitivity Level (MSL) of the substitute part?

A: The 2347091-1 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are there inventory considerations when transitioning from 204976 to 2347091-1?

A: Current inventory of 204976 is 18,905 units (new original stock), while 2347091-1 inventory is 957 units. For high-volume applications, lead time and availability should be evaluated with the supplier.

Q: What electrical parameters remain constant between these parts?

A: Current Rating (1.5 A), Voltage Rating (500VAC), and Operating Temperature Range (-55°C ~ 125°C) are identical, ensuring electrical compatibility in all specified operating conditions.
