Key Parameters

Substitute Part Grouping Explanation

The substitute part 6469152-1 is qualified as a direct equivalent based on the following substitution criteria:

Matching Functional Parameters:

• Connector family: HMZD series
• Configuration: 3PAIR header assembly
• Modular dimension: 37.5MM
• Connector type: Header with male pins and blades
• Mounting method: Through hole
• Termination method: Press-fit

Substitution Logic: The 6469152-1 maintains identical electrical and mechanical interface specifications as the original 973019. Both components serve the same functional role within backplane connector applications. The substitute part is manufactured by TE Connectivity AMP Connectors and carries Active product status with full RoHS3 compliance and EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Ongoing Support:

The 6469152-1 is the qualified substitute for the obsolete 973019. This substitution is supported by:

• Active product status ensuring continued availability and manufacturing support
• RoHS3 compliance meeting current environmental and regulatory requirements
• EAR99 ECCN classification maintaining export control consistency
• Moisture Sensitivity Level 1 indicating no special handling requirements during storage or assembly
• Adequate inventory levels (1137 pieces) supporting production requirements

For Legacy System Maintenance:

Existing installations using 973019 may continue to utilize remaining stock (1066 pieces). When stock depletion occurs, transition to 6469152-1 is the specified path forward based on functional equivalence and connector interface compatibility.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting 973019 with 6469152-1?
