Substitute Part Grouping Explanation

Substitution for the obsolete TE Connectivity Erni 123757 is based on functional equivalence within the HMZD HRD connector family. The manufacturer-recommended substitute is TE Connectivity AMP Connectors part number 6469046-1, which maintains the same connector designation (HMZD HRD ASSY, 4 PAIR) and belongs to the active Z-PACK HM-Zd series.

The substitution logic is determined by the following key parameters:

• Connector designation and assembly type (HMZD HRD ASSY, 4 PAIR)
• Connector family compatibility (Z-PACK HM-Zd series)
• Electrical performance characteristics (voltage, current, contact configuration)
• Physical form factor and mounting interface
• Termination method and contact materials

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 6469046-1 is the manufacturer-designated substitute for the obsolete TE Connectivity Erni 123757. Selection of this substitute is supported by the following factors:

Product Status: The substitute part 6469046-1 maintains active production status, ensuring long-term availability and supply chain reliability compared to the obsolete original part.

Compliance and Certifications: The substitute part carries RoHS compliance certification and UL94 V-0 material flammability rating, meeting current regulatory requirements for electronic component applications.

Moisture Sensitivity: MSL 1 rating indicates unlimited shelf life without moisture control requirements, simplifying inventory management and reducing handling costs.

Export Classification: EAR99 classification provides standard export treatment without additional licensing restrictions.

The substitute part is suitable for direct replacement in applications where the original 123757 was specified, provided that the mechanical and electrical parameters of the substitute align with system requirements.

Frequently Asked Questions (FAQ)

Q: Why is the TE Connectivity Erni 123757 being discontinued?

A: The 123757 is classified as obsolete. Manufacturers discontinue products to consolidate product lines and transition to newer connector families. The Z-PACK HM-Zd series represents the current active product line for this connector type.

Q: Is the 6469046-1 a direct replacement for the 123757?

A: The 6469046-1 is the manufacturer-recommended substitute. Both parts share the same connector designation (HMZD HRD ASSY, 4 PAIR). Compatibility must be verified against specific application requirements, particularly mechanical mounting interfaces and electrical load specifications.

Q: What are the key electrical differences between the original and substitute?

A: The substitute part 6469046-1 specifies a current rating of 0.700A and voltage rating of 250V. The original part specifications are not provided in available documentation. Verify that these ratings meet or exceed your application requirements.

Q: Does the substitute part require different handling or storage?

A: The substitute part carries MSL 1 rating, indicating no moisture sensitivity. This simplifies storage compared to components with higher MSL ratings. Standard ESD precautions for electronic components remain applicable.

Q: What is the pitch specification for the substitute part?

A: The 6469046-1 features a pitch of 0.098" (2.50mm) with 120 total positions arranged in 8 rows and 10 columns. Verify that your PCB layout accommodates this pitch and position count.

Q: Are there any export restrictions on the substitute part?

A: The 6469046-1 carries EAR99 classification, which is the standard export classification for most commercial electronic components. No additional export licenses are required for standard commercial transactions.
