Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 794075-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (16)
• Number of rows (2)
• Pitch spacing (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Locking Ramp)
• Insulation height (0.531" / 13.50mm)
• Contact post length (0.175" / 4.45mm)

Electrical Compatibility Parameters:

• Operating temperature range (-20°C ~ 85°C)
• Voltage rating (600VAC)
• Contact material (Brass)
• Insulation material (Polyamide/Nylon)

Termination & Assembly Parameters:

• Termination method (Solder)
• Board lock feature presence

The substitute part 1-794075-0 maintains full mechanical and electrical equivalence with the 794075-1 across all critical parameters. The primary difference is the contact finish specification: the 794075-1 uses Tin-Lead finish while the 1-794075-0 uses Tin finish. Both finishes meet the 150.0µin (3.81µm) thickness specification and are compatible with solder termination processes.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (794075-1): The 794075-1 is suitable for applications where RoHS non-compliant components are acceptable or required by design specifications. This part maintains active product status and is available in moderate quantities.

Substitute Part Selection (1-794075-0): The 1-794075-0 is the direct substitute for the 794075-1 and is recommended for new designs and applications requiring ROHS3 compliance. This part is functionally equivalent across all mechanical and electrical parameters. The 1-794075-0 offers significantly higher inventory availability (5849 pieces versus 677 pieces) and meets current regulatory compliance requirements.

Contact Finish Consideration: The transition from Tin-Lead to Tin contact finish between the 794075-1 and 1-794075-0 reflects industry-wide compliance with lead-free soldering standards. Both finishes maintain identical thickness specifications (150.0µin / 3.81µm) and are compatible with standard solder termination processes. The Tin finish of the 1-794075-0 is compatible with both lead-free and traditional lead-based solder processes.

Compliance Status: Selection between these parts should consider regulatory requirements. The 1-794075-0 ROHS3 compliance status makes it the preferred choice for applications subject to European Union Restriction of Hazardous Substances regulations or equivalent international standards.

Frequently Asked Questions (FAQ)

Q: Are the 794075-1 and 1-794075-0 mechanically interchangeable?

A: Yes. Both parts are mechanically identical. They share the same connector type, position count (16), row configuration (2 rows), pitch spacing (0.163" / 4.14mm), mounting type (through hole), shrouding (4-wall), and fastening mechanism (locking ramp). Physical dimensions, including insulation height (0.531" / 13.50mm) and contact post length (0.175" / 4.45mm), are identical.

Q: What is the difference between the contact finishes?

A: The 794075-1 uses Tin-Lead contact finish while the 1-794075-0 uses Tin finish. Both finishes are applied at 150.0µin (3.81µm) thickness. The Tin finish of the 1-794075-0 represents a lead-free alternative that complies with current environmental regulations while maintaining electrical and mechanical performance equivalent to the Tin-Lead finish.

Q: Can I use the 1-794075-0 as a direct replacement for the 794075-1?

A: Yes. The 1-794075-0 is a direct substitute for the 794075-1. All electrical parameters (600VAC voltage rating, -20°C to 85°C operating temperature), mechanical specifications, and functional features are identical. The primary consideration is compliance status: the 1-794075-0 is ROHS3 compliant while the 794075-1 is not.

Q: Are there any soldering process differences between these parts?

A: No. Both parts use solder termination and are compatible with standard PCB assembly processes. The Tin finish of the 1-794075-0 is compatible with both lead-free and traditional lead-based solder processes, providing process flexibility.

Q: Which part should I specify for new designs?

A: The 1-794075-0 is recommended for new designs. It offers ROHS3 compliance, higher inventory availability (5849 pieces), and maintains full functional equivalence with the 794075-1. Both parts are active products with ongoing manufacturer support.

Q: What is the board lock feature?

A: The board lock feature is a mechanical retention mechanism present on both the 794075-1 and 1-794075-0. This feature provides positive locking engagement with the mating connector, preventing accidental disconnection during operation or handling.

Q: Are these connectors suitable for general-purpose applications?

A: Yes. Both the 794075-1 and 1-794075-0 are rated for general-purpose applications. The 600VAC voltage rating, -20°C to 85°C operating temperature range, and UL94 V-0 flammability rating support use in standard industrial and commercial applications.

Q: What is the current rating for these connectors?

A: The current rating varies by wire gauge. Consult the connector's detailed specifications or application documentation for current ratings corresponding to specific wire gauge selections used in your assembly.
