TE Connectivity Erni 973056 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 973056 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 a 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 973056 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Compatibility Criteria:

• Number of Positions: 60 positions (fixed requirement)
• Pitch: 0.098" (2.50mm) (fixed requirement for PCB footprint compatibility)
• Connector Type: Header with male pins (functional requirement)
• Mounting Type: Through Hole (assembly process requirement)
• Termination: Press-Fit (manufacturing compatibility)
• Contact Finish: Gold (electrical performance and corrosion resistance)

Secondary Compliance Criteria:

• RoHS3 Compliance (regulatory requirement)
• MSL Rating: 1 (storage and handling compatibility)
• REACH Status: REACH Unaffected (supply chain compliance)

The substitute part TE Connectivity AMP Connectors 6469025-1 satisfies all primary compatibility criteria and secondary compliance requirements. Variations in row/column configuration (4 rows × 10 columns versus 6 rows) are acceptable provided the 60-position count and 2.50mm pitch are maintained, as these determine PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6469025-1 is the designated substitute for the obsolete TE Connectivity Erni 973056 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain 60-position configuration with 0.098" (2.50mm) pitch, ensuring PCB footprint compatibility. The substitute provides specified electrical ratings (0.700A current, 250V voltage) where the original part specifications were not provided.

Mechanical Compatibility: Both connectors utilize through-hole mounting with press-fit termination, maintaining assembly process compatibility. The row/column configuration difference (6 rows versus 4 rows × 10 columns) does not affect functional compatibility as the total position count and pitch remain constant.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Rating 1, satisfying current regulatory and supply chain requirements.

Product Status: The substitute part is active and in production, with 16,754 pieces in stock, providing supply chain continuity for the obsolete original part.

Temperature Operating Range: The substitute operates across -65°C to 105°C, which encompasses the majority of the original part's -55°C to 125°C range. Applications requiring operation above 105°C require design review.

Frequently Asked Questions (FAQ)

Q: Can the 6469025-1 substitute directly replace the 973056 in existing designs?

A: The 6469025-1 maintains the same 60-position count, 0.098" (2.50mm) pitch, through-hole mounting, and press-fit termination as the 973056. PCB footprints designed for the original part are compatible with the substitute. The row/column configuration difference does not affect mechanical or electrical compatibility for backplane connector applications.

Q: What is the significance of the "Male Pins and Blades" designation in the substitute part?

A: The 6469025-1 includes both male pins and blades as contact elements, whereas the 973056 specifies male pins only. This configuration supports high-speed backplane applications with improved signal integrity. The presence of blade contacts does not prevent compatibility with standard male pin receptacles.

Q: Are there temperature range differences between the two parts?

A: The 973056 operates from -55°C to 125°C, while the 6469025-1 operates from -65°C to 105°C. The substitute provides lower minimum temperature capability but does not extend to the original part's maximum temperature. Applications requiring sustained operation above 105°C require alternative component selection.

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

A: The 6469025-1 specifies a gold contact finish thickness of 30.0µin (0.76µm). The original 973056 does not provide contact finish thickness data. This specification ensures consistent electrical performance and corrosion resistance across the connector's operational life.

Q: How does the "High Speed" designation of the substitute part affect compatibility?

A: The 6469025-1 is designated as a high-speed connector within the Z-PACK HM-Zd series, indicating optimized signal integrity characteristics. This enhancement does not compromise compatibility with standard backplane applications. Designs utilizing the original 973056 benefit from improved electrical performance with the substitute part.

Q: What is the current rating specification for the substitute part?

A: The 6469025-1 is rated for 0.700A per contact. The original 973056 does not provide a current rating specification. This rating applies to individual contact elements and must be considered in circuit design calculations for the backplane application.

Q: Are both parts compliant with current regulatory standards?

A: Both the 973056 and 6469025-1 are ROHS3 compliant and REACH unaffected. Both carry MSL Rating 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040 for export and tariff purposes.

Q: What packaging format is provided for the substitute part?

A: The 6469025-1 is supplied in tube packaging. The original 973056 packaging format is not specified in the available data. Tube packaging is standard for backplane connector distribution and is compatible with automated assembly processes.
