Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-794632-4 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.118" / 3.00mm)
• Row spacing - mating (0.118" / 3.00mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Press-Fit, Solder)

Electrical Compatibility Parameters:

• Voltage rating (250V)
• Operating temperature range (-40°C ~ 105°C)
• Series designation (Micro MATE-N-LOK)

Physical Compatibility Parameters:

• Contact shape (Square)
• Insulation material (Polyamide / Nylon)
• Insulation height (0.364" / 9.25mm)
• Contact post length (0.125" / 3.18mm)
• Contact post thickness (100.0µin / 2.54µm)

Substitute parts must maintain identical values across all listed parameters to ensure direct functional and mechanical interchangeability without design modification or board rework.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-794632-4 is the direct substitute for the obsolete 2-794632-4 connector header. Both parts share identical mechanical and electrical specifications across all critical parameters, including connector type, position count, pitch, mounting configuration, voltage rating, and operating temperature range.

Product Status Advantage: The 5-794632-4 maintains active product status with significantly higher inventory availability (18,302 pieces in stock versus 1,112 pieces for the obsolete 2-794632-4). This ensures reliable supply chain access for ongoing production and replacement applications.

Compliance Improvement: The 5-794632-4 is RoHS Compliant, whereas the 2-794632-4 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part provides enhanced regulatory alignment.

Contact Finish Consideration: The primary technical difference is the contact post finish: the 2-794632-4 uses Tin-Lead, while the 5-794632-4 uses Tin. Both finishes maintain the same thickness specification (100.0µin / 2.54µm) and are functionally equivalent for solder and press-fit termination applications. The Tin finish in the substitute part aligns with lead-free manufacturing standards.

Packaging: The 5-794632-4 is supplied in Tray packaging, providing standard handling and storage compatibility with modern assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 5-794632-4 be used as a direct replacement for the 2-794632-4 without PCB modification?

A: Yes. The 5-794632-4 is mechanically and electrically identical to the 2-794632-4 across all critical parameters. No PCB rework or design changes are required. The connector footprint, mounting hole pattern, and electrical performance are fully compatible.

Q: What is the significance of the contact post finish difference (Tin-Lead versus Tin)?

A: Both finishes provide equivalent solder wetting and press-fit contact performance. The Tin finish in the 5-794632-4 reflects modern lead-free manufacturing practices and is functionally interchangeable with the Tin-Lead finish of the 2-794632-4 for all standard termination methods.

Q: Why is the 2-794632-4 listed as obsolete?

A: The 2-794632-4 has been superseded by the 5-794632-4 in the TE Connectivity product line. The substitute part offers improved compliance status (RoHS Compliant), active product support, and superior inventory availability.

Q: Are there any electrical performance differences between these parts?

A: No. Both connectors are rated for 250V operation, support the same current capacity (varies by wire gauge), and operate across the identical temperature range of -40°C to 105°C. Electrical performance is fully equivalent.

Q: What packaging options are available for the substitute part?

A: The 5-794632-4 is supplied in Tray packaging. This is the standard packaging format for this connector series and is compatible with automated assembly equipment.

Q: Is the 5-794632-4 suitable for applications requiring RoHS compliance?

A: Yes. The 5-794632-4 is RoHS Compliant, making it suitable for applications and markets with RoHS regulatory requirements. The 2-794632-4 is RoHS non-compliant.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The mechanical and electrical specifications are identical, allowing both parts to be used interchangeably in the same design without functional impact. However, the 5-794632-4 is recommended for new designs and ongoing production due to its active status and improved compliance profile.

Q: What is the mating pitch for these connectors?

A: Both connectors feature a 0.118" (3.00mm) mating pitch with identical row spacing of 0.118" (3.00mm), ensuring compatibility with standard Micro MATE-N-LOK receptacle connectors.
