Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 973046 is based on the following critical parameters that must align for functional compatibility:

Primary Matching Criteria:

• Number of Positions: 60 (exact match required)
• Pitch: 0.098" (2.50mm) (exact match required)
• Connector Type: Receptacle, Female Sockets (exact match required)
• Termination: Press-Fit (exact match required)
• Contact Finish: Gold (exact match required)
• Mounting Type: Through Hole, Right Angle (exact match required)

Secondary Compliance Criteria:

• RoHS3 Compliance (required for regulatory alignment)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

The substitute part TE Connectivity AMP Connectors 6469028-1 satisfies all primary matching criteria and maintains compliance with secondary requirements. While the substitute exhibits differences in row/column configuration (4 rows × 10 columns versus 6 rows), contact layout specification (40 Signal, 20 Ground), and operating temperature range, these variations do not preclude functional substitution when the mechanical and electrical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The TE Connectivity Erni 973046 is classified as obsolete. The substitute part TE Connectivity AMP Connectors 6469028-1 carries an active product status, ensuring ongoing availability, manufacturing support, and compliance with current industry standards.

Regulatory Compliance

Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement and deployment.

Inventory and Supply Chain

The substitute part 6469028-1 maintains significantly higher inventory levels (24,863 pieces in stock) compared to the main part (4,275 pieces), providing improved supply chain reliability and reduced lead times for procurement.

Functional Compatibility

The substitute maintains critical interface parameters: 60-position count, 0.098" (2.50mm) pitch, press-fit termination, gold contact finish, and through-hole right-angle mounting. These parameters ensure mechanical and electrical compatibility with existing mating components and PCB layouts designed for the original part.

Operating Conditions

The substitute part operates across a temperature range of -65°C to 105°C, which encompasses the lower bound of the original part's range (-55°C) but does not extend to the upper limit (125°C). Applications requiring operation above 105°C require evaluation against specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP Connectors 6469028-1 be used as a direct replacement for the TE Connectivity Erni 973046?

A: The substitute part satisfies the critical interface requirements: 60 positions, 0.098" (2.50mm) pitch, press-fit termination, gold contacts, and through-hole right-angle mounting. Compatibility depends on whether the application can accommodate the differences in row configuration (4 rows × 10 columns versus 6 rows) and the specified contact layout (40 Signal, 20 Ground).

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) row/column configuration—the substitute uses 4 rows × 10 columns versus 6 rows for the original; (2) mounting style—the substitute specifies board edge mounting in addition to through-hole; (3) operating temperature range—the substitute operates to 105°C maximum versus 125°C for the original; (4) electrical specifications—the substitute provides rated current (0.700A) and voltage (250V) not specified for the original.

Q: Are both parts RoHS compliant?

A: Yes, both the TE Connectivity Erni 973046 and the TE Connectivity AMP Connectors 6469028-1 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or deployment.

Q: Does the substitute part have better availability?

A: Yes, the substitute part 6469028-1 is classified as active product status with 24,863 pieces in stock, compared to the obsolete main part with 4,275 pieces available. This provides improved long-term supply chain reliability.

Q: Can I use the substitute in applications requiring operation above 105°C?

A: The substitute part is rated for operation up to 105°C maximum. Applications requiring sustained operation above this temperature require evaluation of alternative solutions or confirmation that peak temperatures remain within the substitute's operating range.

Q: What is the contact finish thickness of the substitute part?

A: The substitute part TE Connectivity AMP Connectors 6469028-1 specifies a contact finish thickness of 30.0µin (0.76µm) gold plating.

Q: Are the termination methods compatible?

A: Yes, both connectors use press-fit termination, ensuring compatibility with existing PCB design and assembly processes.
