Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 973032 is based on the following critical parameters that must align for functional compatibility:

Core Matching Parameters:

• Number of Positions: 120 (exact match required)
• Connector Type: Receptacle, Female Sockets (exact match required)
• Pitch: 0.098" (2.50mm) (exact match required)
• Termination: Press-Fit (exact match required)
• Contact Finish: Gold (exact match required)
• Mounting Type: Through Hole, Right Angle (exact match required)

Allowable Variations:

• Number of Rows: May differ (12 rows in main part vs. 8 rows in substitute) when total position count remains 120
• Number of Columns: May differ (substitute specifies 10 columns) when total position count remains 120
• Operating Temperature Range: Substitute range (-65°C ~ 105°C) represents a subset of the main part range (-55°C ~ 125°C) and is acceptable for applications within the substitute's specified limits
• Series Designation: May differ (ERMET ZD vs. Z-PACK HM-Zd) as long as electrical and mechanical parameters align
• Connector Style: Substitute introduces "High Speed" designation, which is a performance enhancement and does not preclude substitution

The substitute part TE Connectivity AMP Connectors 6469001-1 satisfies all core matching parameters while offering additional specifications including current rating (0.700A), voltage rating (250V), and enhanced flammability rating (UL94 V-0).

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 6469001-1

The TE Connectivity AMP Connectors 6469001-1 is the manufacturer-recommended substitute for the obsolete TE Connectivity Erni 973032. This substitution is supported by the following factors:

Compliance and Status:

• The substitute part maintains active product status, ensuring ongoing availability and manufacturing support
• Both parts are RoHS compliant, meeting current environmental regulations
• Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence

Electrical and Mechanical Compatibility:

• All critical parameters align: 120 positions, 0.098" (2.50mm) pitch, press-fit termination, gold contact finish, through-hole right-angle mounting
• The substitute provides specified electrical ratings (0.700A current, 250V voltage) and enhanced material flammability rating (UL94 V-0), representing performance improvements over the main part
• Both parts maintain unlimited moisture sensitivity level (MSL 1)

Physical Configuration:

• The substitute employs an 8-row by 10-column configuration versus the main part's 12-row layout, while maintaining identical 120-position count
• Board edge mounting capability in the substitute provides additional application flexibility
• Contact layout specification (80 Single Signal, 40 Ground) in the substitute ensures defined signal distribution

Temperature Consideration:

• The substitute operating temperature range (-65°C ~ 105°C) is narrower than the main part (-55°C ~ 125°C). Applications requiring operation above 105°C or below -65°C must retain the original part or identify alternative solutions

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP Connectors 6469001-1 directly replace the TE Connectivity Erni 973032 in all applications?

A: The substitute part satisfies all core electrical and mechanical parameters required for functional replacement. However, applications operating outside the substitute's temperature range (-65°C ~ 105°C) require evaluation against the original part's extended range (-55°C ~ 125°C). The substitute's board edge mounting capability may require PCB layout verification in existing designs.

Q: What is the significance of the different row and column configurations (12 rows vs. 8 rows by 10 columns)?

A: Both configurations deliver 120 total positions with identical 0.098" (2.50mm) pitch. The physical footprint differs due to the alternative arrangement. PCB layout compatibility must be confirmed before substitution, as the connector's mounting pattern and contact positions may require design modification.

Q: Are there compliance or regulatory differences between the main part and substitute?

A: Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications. The substitute provides additional certification (UL94 V-0 flammability rating) not specified for the main part. No regulatory barriers exist for substitution from a compliance standpoint.

Q: Why is the main part classified as obsolete?

A: The TE Connectivity Erni 973032 is no longer in active production. The manufacturer-recommended substitute (6469001-1) represents the current equivalent solution for new designs and ongoing support of existing systems.

Q: What is the significance of the contact layout specification (80 Single Signal, 40 Ground) in the substitute?

A: This specification defines the electrical distribution within the 120-position connector: 80 positions are designated for single-ended signal transmission, and 40 positions are designated for ground connections. This layout ensures proper signal integrity and grounding architecture in backplane applications.

Q: Does the substitute's specified current rating (0.700A) and voltage rating (250V) apply to all 120 positions?

A: The current and voltage ratings represent the electrical specifications for the connector contacts. Application of these ratings depends on the specific signal and power distribution defined by the contact layout and system design requirements.

Q: Is the substitute available in the same packaging as the main part?

A: The substitute is supplied in tube packaging. The main part packaging is not specified in the available data. Packaging format should be confirmed with the supplier for procurement and handling requirements.
