Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 354144 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 125 positions
• Pitch specification: 0.079" (2.00mm)
• Row configuration: 5 rows
• Mounting orientation: Through hole, right angle
• Termination technology: Press-fit
• Shielding requirement: Shielded configuration

The substitute part TE Connectivity AMP Connectors 5352069-1 satisfies all mandatory parameters while providing enhanced specifications in contact finish, voltage rating, and current capacity. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5352069-1 serves as the direct substitute for the obsolete TE Connectivity Erni 354144. Both connectors maintain identical mechanical and electrical interface specifications across all critical parameters: 125-position configuration, 2.00mm pitch, 5-row layout, right-angle through-hole mounting, and press-fit termination.

The substitute part provides additional technical specifications not documented for the original part, including gold contact finish with defined thickness, 500Vrms voltage rating, 1.5A current capacity, and -55°C to 125°C operating temperature range. These specifications ensure compatibility with standard backplane connector applications.

Both parts achieve ROHS3 compliance and maintain MSL 1 rating, confirming suitability for standard manufacturing and storage conditions. The substitute part carries active product status, ensuring long-term availability and supply chain continuity. The Z-PACK series designation of the substitute part indicates current production within TE Connectivity's active connector portfolio.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between the TE Connectivity Erni 354144 and its substitute?

A: Compatibility is established through matching of core mechanical and electrical interface parameters: 125-position count, 2.00mm pitch, 5-row configuration, right-angle through-hole mounting, press-fit termination, and shielded design. These parameters ensure direct functional equivalence in backplane connector applications.

Q: Why is the TE Connectivity AMP 5352069-1 recommended as a substitute?

A: The 5352069-1 satisfies all mandatory interface parameters while providing documented electrical specifications and active product status. The original part's obsolete classification necessitates transition to an actively manufactured equivalent.

Q: Are there packaging differences between these connectors?

A: The original part packaging is not specified in available documentation. The substitute part is supplied in tube packaging. Packaging format should be confirmed with procurement requirements for your application.

Q: What is the significance of the shielding difference notation?

A: The original part is specified as shielded. The substitute part specifies upper shield configuration. Both provide electromagnetic interference protection appropriate for backplane connector applications. The specific shield geometry should be verified against mechanical layout requirements.

Q: Do the unspecified parameters on the original part affect substitution validity?

A: No. The substitute part's documented specifications (gold contact finish, 500Vrms rating, 1.5A capacity, -55°C to 125°C range) represent standard performance levels for this connector class and do not introduce incompatibility. These specifications define the electrical operating envelope for the substitute part.

Q: What compliance certifications apply to both parts?

A: Both connectors achieve ROHS3 compliance and maintain MSL 1 (unlimited moisture sensitivity) rating. The substitute part's REACH status is listed as vendor undefined; the original part is REACH unaffected. Both parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.
