TE Connectivity Erni 973063 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 973063 is a 60-position backplane connector header with male pins designed for through-hole mounting applications. This component features press-fit termination and operates across an industrial temperature range of -55°C to 125°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs. Substitute parts must maintain electrical compatibility, mechanical fit, and performance characteristics suitable for backplane connector applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 973063 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Compatibility Criteria:

• Number of Positions: 60 (exact match required)
• Pitch: 0.098" (2.50mm) (exact match required)
• Connector Type: Header with male pins (functional equivalence)
• Mounting Type: Through Hole (exact match required)
• Termination Method: Press-Fit (exact match required)
• Contact Finish: Gold (exact match required)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Secondary Considerations:

• Connector Category: Backplane Connectors
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part 6469076-1 satisfies all primary compatibility criteria. While the substitute exhibits different row/column configuration (4 rows × 10 columns versus 6 rows), the total position count of 60 and pitch of 2.50mm remain constant, ensuring mechanical and electrical interchangeability in backplane applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6469076-1 is the designated substitute for the obsolete TE Connectivity Erni 973063 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical pitch (2.50mm) and position count (60), ensuring direct mechanical and electrical interchangeability in backplane connector applications. The substitute provides specified electrical ratings (0.700A current, 250V voltage) that were not documented for the main part.

Regulatory Compliance: Both parts achieve ROHS3 compliance and maintain REACH Unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Product Lifecycle Status: The main part 973063 is classified as obsolete, while the substitute 6469076-1 maintains active product status with documented inventory availability (2200 pieces). This transition ensures continued supply chain viability and manufacturer support.

Thermal Operating Range: The substitute operates across -65°C to 105°C, which overlaps substantially with the main part's -55°C to 125°C range. Applications requiring the full -55°C to 125°C specification should be evaluated against the substitute's -65°C to 105°C capability.

Connector Configuration: The substitute employs a 4-row × 10-column arrangement versus the main part's 6-row configuration. Both configurations deliver 60 total positions at identical 2.50mm pitch, maintaining footprint compatibility for backplane applications.

Frequently Asked Questions (FAQ)

Q: Can the 6469076-1 substitute directly replace the 973063 in existing designs?

A: Yes, for applications within the overlapping operating temperature range (-55°C to 105°C). The 60-position count, 2.50mm pitch, through-hole mounting, and press-fit termination are identical. PCB layout must accommodate the different row/column configuration (4×10 versus 6-row), though the overall connector footprint remains compatible for backplane applications.

Q: What is the primary reason for substitution?

A: The TE Connectivity Erni 973063 is classified as obsolete. The 6469076-1 is an active product from TE Connectivity AMP Connectors with confirmed inventory availability, ensuring reliable procurement for new designs and production continuity.

Q: Are there differences in electrical performance between these parts?

A: The substitute 6469076-1 provides documented electrical specifications: 0.700A current rating and 250V voltage rating. The main part 973063 did not include published electrical ratings. Both parts use gold contact finish and maintain identical pitch and position count.

Q: Does the different row/column arrangement affect compatibility?

A: The row/column configuration differs (4 rows × 10 columns for the substitute versus 6 rows for the main part), but both maintain 60 total positions at 2.50mm pitch. PCB layout and connector mounting patterns must be verified for the specific application, though backplane connector applications typically accommodate this variation.

Q: What is the operating temperature difference, and does it matter?

A: The main part operates -55°C to 125°C; the substitute operates -65°C to 105°C. Applications requiring operation above 105°C or below -65°C must be evaluated separately. For standard industrial applications within -55°C to 105°C, both parts are functionally equivalent.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 973063 and 6469076-1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement and use.

Q: What packaging differences exist between these parts?

A: The main part 973063 is supplied in trays; the substitute 6469076-1 is supplied in tubes. Packaging format should be confirmed with procurement requirements and inventory management systems.

Q: Is the contact finish identical?

A: Both parts feature gold contact finish. The substitute specifies contact finish thickness of 30.0µin (0.76µm), while the main part does not document this specification. The gold finish ensures equivalent electrical performance and corrosion resistance.
