Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-794630-0 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Connector series: Micro MATE-N-LOK
• Number of positions: 10
• Number of rows: 2
• Pitch spacing: 0.118" (3.00mm)
• Voltage rating: 250V
• Operating temperature range: -40°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector type: Header
• Contact type: Male Pin
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Press-Fit, Solder
• Fastening type: Locking Ramp
• Insulation material: Polyamide (PA), Nylon
• Insulation height: 0.364" (9.25mm)
• Contact post length: 0.125" (3.18mm)

Compliance Parameters:

• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 4-794630-0 maintains all critical electrical and mechanical parameters. Variations exist only in packaging format (Tray versus standard packaging) and contact finish composition (Tin versus Tin-Lead), which do not affect functional compatibility in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-794630-0 is a direct functional equivalent to the 1-794630-0 for all board-to-cable/wire connector applications within the specified electrical and mechanical parameters.

Selection Basis:

Both parts maintain identical electrical ratings (250V, -40°C to 105°C operating range), mechanical dimensions (10-position, 2-row, 0.118" pitch), and compliance certifications (UL94 V-0 flammability rating, MSL 1). The substitute part 4-794630-0 carries RoHS compliance certification, while the main part carries ROHS3 compliance. Both certifications satisfy current regulatory requirements for their respective product statuses.

The contact finish difference (Tin-Lead on 1-794630-0 versus Tin on 4-794630-0) does not affect functional compatibility. Both finishes provide equivalent electrical conductivity and corrosion resistance for the specified voltage and temperature operating envelope.

The packaging variation (Tray format for 4-794630-0) represents a logistical difference only and does not impact connector performance or compatibility with mating components.

Selection between these parts should be based on inventory availability, packaging requirements, and supply chain considerations. The 4-794630-0 currently maintains higher inventory levels (6661 pieces versus 958 pieces for the main part).

Frequently Asked Questions (FAQ)

Q: Can the 4-794630-0 be used as a direct replacement for the 1-794630-0 in existing designs?

A: Yes. The 4-794630-0 maintains identical electrical ratings, mechanical dimensions, pitch spacing, and mounting characteristics. No design modifications are required for substitution.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: Both finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating parameters. The contact finish composition does not affect mating performance, current-carrying capacity, or voltage rating for this connector series.

Q: Does the packaging format (Tray versus standard) affect connector functionality?

A: No. Packaging format is a logistics and handling consideration only. The connector itself maintains identical electrical and mechanical specifications regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. The 1-794630-0 is ROHS3 compliant, and the 4-794630-0 is RoHS compliant. Both meet current regulatory requirements for their respective product classifications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can these connectors be used interchangeably with other Micro MATE-N-LOK series headers?

A: Interchangeability is limited to connectors with identical position count (10), row configuration (2 rows), and pitch spacing (0.118"). Verify all mechanical and electrical parameters before substitution.

Q: What termination methods are supported?

A: Both connectors support Press-Fit and Solder termination methods, providing flexibility for through-hole assembly processes.

Q: Is there a difference in current rating between these parts?

A: Current rating varies by wire gauge for both parts. Consult wire gauge specifications and application requirements to determine appropriate current capacity.
