Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 354148 is based on alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Pitch: 0.079" (2.00mm)
• Mounting type: Through Hole, Right Angle
• Termination method: Press-Fit
• Connector style: B 22
• Shielding capability: Present

Position Count Consideration: The substitute part TE Connectivity AMP Connectors 5352152-1 provides 120 positions (110 signal + 10 ground) compared to the 110 positions of the main part. This configuration maintains full compatibility with the original 110-position signal requirement while adding dedicated ground positions, which is a standard design evolution in backplane connector technology.

Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory standing.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5352152-1 serves as the active equivalent for the obsolete TE Connectivity Erni 354148. Selection of this substitute is supported by the following factors:

Product Status Alignment: The substitute part maintains active production status, ensuring long-term component availability and supply chain continuity. The main part's obsolete classification creates supply risk that the substitute directly addresses.

Compliance Certification: Both components maintain identical ROHS3 compliance and MSL 1 ratings, confirming equivalent environmental and regulatory standing for applications requiring these certifications.

Functional Compatibility: The substitute maintains all critical mechanical and electrical parameters: identical pitch (2.00mm), mounting configuration (through-hole right-angle), termination method (press-fit), and connector style (B 22). The addition of 10 dedicated ground positions represents a design enhancement rather than a functional deviation.

Electrical Specifications: The substitute provides specified electrical ratings (1.5 A current, 500Vrms voltage, -55°C to 125°C operating range) that establish a defined performance envelope for applications where the main part lacked published specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5352152-1 directly replace the TE Connectivity Erni 354148 in existing designs?

A: Yes, the substitute maintains identical pitch (2.00mm), mounting type (through-hole right-angle), termination method (press-fit), and connector style (B 22). The 120-position configuration accommodates the original 110-position requirement with additional ground positions.

Q: What is the significance of the additional 10 ground positions in the substitute part?

A: The substitute provides 110 signal positions plus 10 dedicated ground positions, totaling 120 positions. This configuration maintains full compatibility with the original 110-position signal requirement while providing enhanced grounding capability, which is standard in modern backplane connector design.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is not specified. The substitute is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Yes, both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming equivalent regulatory and environmental standing.

Q: What electrical performance specifications apply to the substitute part?

A: The substitute is rated for 1.5 A current, 500Vrms voltage, and operates across -55°C to 125°C temperature range. The main part does not provide published electrical specifications.

Q: Are the shielding configurations equivalent?

A: Both parts incorporate shielding. The main part is specified as shielded, while the substitute features an upper shield configuration. Both provide electromagnetic shielding for backplane applications.

Q: What is the contact finish specification for the substitute?

A: The substitute features gold-plated contacts with 30.0µin (0.76µm) thickness. The main part does not specify contact finish.
