Engineering Selection Recommendations

The 6469286-1 substitute part is suitable for direct replacement of the obsolete 973099 based on the following engineering criteria:

Product Status Alignment: The original part 973099 carries obsolete status, indicating discontinued production and limited future availability. The substitute 6469286-1 maintains active product status within the TE Connectivity AMP Connectors product line, ensuring continued supply, technical support, and manufacturing consistency.

Compliance & Certification: The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components. These certifications support long-term system compliance and reduce regulatory risk in new designs or system updates.

Electrical & Mechanical Equivalence: All critical electrical parameters (current rating, voltage rating, contact configuration) and mechanical specifications (pitch, mounting type, termination method) are identical between the original and substitute parts. This equivalence ensures direct functional replacement without circuit redesign or mechanical modification.

Connector Series: The substitute part belongs to the Z-PACK HM-Zd series, representing the current generation of high-speed board edge connectors from TE Connectivity, providing access to updated manufacturing processes and quality standards.

Frequently Asked Questions (FAQ)

Q: Can the 6469286-1 be used as a direct replacement for the 973099 in existing applications?

A: Yes. The substitute part maintains identical electrical ratings (0.700A, 250V), mechanical configuration (144 positions, 0.098" pitch, board edge right-angle mounting), and contact specifications (gold finish, press-fit termination). No circuit modifications or mechanical redesign is required.

Q: What is the primary reason for substitution?

A: The original part 973099 is classified as obsolete and no longer in production. The 6469286-1 substitute provides equivalent functionality while maintaining active product status and continued availability from TE Connectivity.

Q: Are there packaging differences between the original and substitute parts?

A: The original part 973099 packaging is not specified in available documentation. The substitute 6469286-1 is supplied in tube packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The 6469286-1 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Q: What is the operating temperature range for the substitute part?

A: The 6469286-1 operates across -65°C to 105°C, matching the original part specification and supporting applications across industrial, commercial, and extended temperature environments.

Q: Are there any differences in contact finish specifications?

A: Both parts feature gold contact finish. The substitute specifies 30.0µin (0.76µm) contact finish thickness, ensuring consistent electrical performance and corrosion resistance.

Q: What is the connector usage classification for the substitute part?

A: The 6469286-1 is classified for daughtercard connector usage, supporting modular system architectures and board-to-board interconnection applications.
