Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794108-2 connector header is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.163" / 4.14mm)
• Row spacing - mating (0.163" / 4.14mm)
• Mounting type (through hole, right angle)
• Shrouding configuration (shrouded - 4 wall)

Electrical Compatibility:

• Connector type (header)
• Contact type (male pin)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 105°C)

Manufacturing Compatibility:

• Termination method (solder)
• Series designation (Mini-Universal MATE-N-LOK)
• Contact material (brass)
• Insulation material (polyamide/nylon)

The substitute part 1-794108-1 maintains identical mechanical and electrical specifications while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 1-794108-1 connector header serves as the direct active equivalent to the obsolete 794108-2. Both components maintain identical mechanical and electrical specifications across all critical mating and mounting parameters, ensuring direct form-fit-function compatibility.

Key Differentiators:

The substitute part 1-794108-1 offers two significant advantages over the main part:

1. Product Status: The 1-794108-1 maintains active product status with TE Connectivity, ensuring ongoing availability, technical support, and supply chain continuity. The 794108-2 is classified as obsolete and subject to discontinuation.

2. Regulatory Compliance: The 1-794108-1 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 794108-2 is RoHS non-compliant, which may present regulatory barriers in applications subject to RoHS directives.

3. Contact Finish - Post: The 1-794108-1 features tin plating on the post termination, while the 794108-2 uses tin-lead plating. This change aligns with lead-free manufacturing standards and RoHS compliance requirements.

For new designs and ongoing production, the 1-794108-1 is the appropriate selection. For legacy system maintenance where the 794108-2 is currently installed, the 1-794108-1 provides direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1-794108-1 be used as a direct replacement for the 794108-2 in existing assemblies?

A: Yes. The 1-794108-1 maintains identical mechanical and electrical specifications including pitch, row spacing, number of positions, mounting type, and voltage rating. Direct substitution is supported without PCB or cable assembly modifications.

Q: What is the difference between the contact finish specifications?

A: The 794108-2 uses tin-lead plating on the post termination, while the 1-794108-1 uses tin plating. Both maintain the same 150.0µin (3.81µm) thickness. The tin finish on the 1-794108-1 aligns with lead-free manufacturing standards and RoHS compliance.

Q: Why is the 794108-2 listed as obsolete?

A: The 794108-2 has been superseded by the 1-794108-1 in TE Connectivity's product portfolio. The newer variant offers improved regulatory compliance and active product support.

Q: Are there packaging differences between these parts?

A: The 794108-2 packaging specification is not provided in the technical data. The 1-794108-1 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts maintain identical voltage rating (600VAC), operating temperature range (-20°C ~ 105°C), and contact specifications.

Q: Can I use the 1-794108-1 in applications originally designed for the 794108-2?

A: Yes. The 1-794108-1 is electrically and mechanically equivalent. It is suitable for all applications where the 794108-2 was specified, with the added benefit of active product status and regulatory compliance.

Q: What is the inventory status for these parts?

A: The 794108-2 has 1095 pieces in stock (obsolete status). The 1-794108-1 has 1249 pieces in stock (active status). For new orders, source the 1-794108-1 to ensure long-term availability.
