Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 966444-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (4)
• Pitch - mating (0.100" / 2.54mm)
• Contact finish - mating (Gold)
• Termination method (Kinked Pin, Solder)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Series designation (AMPMODU HV-100)
• Insulation material (Polyester, Glass Filled)

Regulatory Compliance Parameters:

• RoHS compliance status
• Moisture Sensitivity Level (MSL 1)

The substitute part 5-966444-4 maintains all critical electrical and mechanical parameters while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The 5-966444-4 serves as a direct functional equivalent to the obsolete 966444-4 for all board-to-board rectangular connector applications requiring 4-position, 0.100" pitch receptacle configurations with gold-plated contacts and through-hole solder termination.

Selection Basis:

The substitute part maintains identical electrical and mechanical specifications across all critical parameters: connector type, contact configuration, position count, mating pitch, mounting methodology, and termination approach. Both parts are manufactured by TE Connectivity within the AMPMODU HV-100 series and comply with RoHS regulations and MSL 1 moisture sensitivity requirements.

The primary distinction is product status: the 5-966444-4 maintains active manufacturing status, ensuring long-term availability and supply chain continuity. The main part 966444-4 is classified as obsolete, limiting future procurement options.

For new designs and production applications, the 5-966444-4 is the appropriate selection. For legacy system maintenance where existing inventory of 966444-4 remains available, both parts are electrically and mechanically interchangeable within the same application context.

Frequently Asked Questions (FAQ)

Q: Can the 5-966444-4 directly replace the 966444-4 in existing applications?

A: Yes. Both parts are identical in connector type, contact configuration, position count, mating pitch, mounting type, and termination method. They are mechanically and electrically interchangeable for board-to-board applications.

Q: What is the primary reason for substitution?

A: The 966444-4 is classified as obsolete. The 5-966444-4 is an active product offering equivalent functionality with assured manufacturing continuity.

Q: Are there differences in contact finish specifications?

A: Both parts feature gold-plated mating contacts. The contact finish thickness differs: 966444-4 specifies 5.00µin (0.127µm), while 5-966444-4 specifies 31.5µin (0.80µm). Both thicknesses are within acceptable ranges for gold plating on connector contacts.

Q: Do both parts meet the same regulatory requirements?

A: Both parts comply with RoHS regulations and carry MSL 1 (Unlimited) moisture sensitivity ratings. The main part is ROHS3 compliant; the substitute is RoHS compliant. Both meet ECCN EAR99 and HTSUS 8536.69.4040 classifications.

Q: What is the difference in fastening type specifications?

A: The main part 966444-4 specifies push-pull fastening. The substitute 5-966444-4 does not specify fastening type in the provided data. This does not indicate incompatibility; it reflects data completeness differences between part documentation.

Q: Are both parts available for immediate procurement?

A: Yes. The main part has 1057 pieces in stock; the substitute has 769 pieces in stock. Both are listed as new original inventory.

Q: Which part should be selected for new production designs?

A: The 5-966444-4 should be selected for new designs due to its active product status, ensuring long-term supply chain availability and manufacturing support.
