TE Connectivity AMP Connectors 1-794631-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-794631-0 is a rectangular connector header classified as a Micro MATE-N-LOK series component. This through-hole mounted connector features 10 positions arranged in 2 rows with 0.118" (3.00mm) pitch spacing, designed for board-to-cable/wire applications. The connector employs shrouded 4-wall construction with press-fit and solder termination options, supporting a 250V voltage rating across an operating temperature range of -40°C to 105°C.

The 1-794631-0 carries an obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Active substitute components maintain identical electrical and mechanical specifications while offering improved availability and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-794631-0 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 4-794631-0 maintains identical specifications in the following key areas:

Electrical Parameters: Voltage rating of 250V, operating temperature range of -40°C to 105°C, and current rating varying by wire gauge remain unchanged.

Mechanical Parameters: Connector type (Header), contact type (Male Pin), number of positions (10), row configuration (2 rows), mating pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), mounting method (Through Hole), shrouding style (Shrouded - 4 Wall), and termination options (Press-Fit, Solder) are identical.

Physical Dimensions: Contact post length (0.125"/3.18mm), insulation height (0.364"/9.25mm), contact shape (Square), and insulation material (Polyamide/Nylon) match exactly.

Contact Specifications: Contact material (Brass), mating contact finish (Gold at 15.0µin/0.38µm), and post contact finish thickness (100.0µin/2.54µm) are equivalent.

The primary distinction between the main part and substitute relates to product status (obsolete versus active), packaging format, and post-contact finish composition, with no impact on functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 4-794631-0 serves as the direct functional equivalent to the obsolete 1-794631-0 within the Micro MATE-N-LOK rectangular connector series. Both components share identical electrical performance characteristics, mechanical dimensions, and contact specifications, ensuring direct interchangeability in circuit board applications.

The 4-794631-0 is designated as an active product with current manufacturing support, providing supply chain continuity for new designs and production requirements. This substitute carries RoHS Compliant certification, whereas the original part lists RoHS status as not applicable. The post-contact finish differs between the two parts: the 1-794631-0 employs Tin-Lead plating while the 4-794631-0 uses Tin plating. Both finishes maintain the specified 100.0µin (2.54µm) thickness and are compatible with standard solder assembly processes.

Selection of the 4-794631-0 is appropriate for applications requiring compliance with current environmental regulations and access to active manufacturing inventory. The component maintains all critical performance parameters necessary for board-to-cable/wire connectivity in general-purpose applications across the specified -40°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are the 1-794631-0 and 4-794631-0 mechanically interchangeable?

A: Yes. Both components feature identical mounting configurations (through-hole), shrouding geometry (shrouded 4-wall), position count (10 positions in 2 rows), and pitch spacing (0.118"/3.00mm). Physical board layout and mating interface requirements are identical.

Q: What is the difference in contact finish between these two parts?

A: The 1-794631-0 features Tin-Lead post contact finish, while the 4-794631-0 uses Tin post contact finish. Both maintain 100.0µin (2.54µm) thickness. The mating contact finish (Gold at 15.0µin/0.38µm) is identical on both parts. Both finishes are compatible with standard solder assembly processes.

Q: Does the RoHS compliance difference affect compatibility?

A: No. The RoHS Compliant status of the 4-794631-0 indicates compliance with environmental regulations but does not alter electrical or mechanical performance. The component remains functionally equivalent to the 1-794631-0 in all circuit applications.

Q: What is the significance of the product status change from obsolete to active?

A: The active status of the 4-794631-0 indicates current manufacturing support and availability through standard distribution channels. The obsolete status of the 1-794631-0 reflects discontinuation of production. For new designs and ongoing procurement, the 4-794631-0 provides assured supply continuity.

Q: Are the packaging formats interchangeable for assembly operations?

A: The 1-794631-0 packaging is not specified in available documentation, while the 4-794631-0 is supplied in Tray packaging. Assembly operations should confirm packaging compatibility with existing pick-and-place equipment and material handling procedures. The connector itself remains functionally identical regardless of packaging format.

Q: Can the 4-794631-0 be used as a direct replacement in existing designs?

A: Yes. The 4-794631-0 maintains all critical electrical and mechanical specifications required for direct substitution. No circuit design modifications or board layout changes are necessary. The component operates within the same voltage (250V), temperature (-40°C to 105°C), and current rating parameters as the original part.

Q: What applications are these connectors suitable for?

A: Both the 1-794631-0 and 4-794631-0 are designated for general-purpose board-to-cable/wire connectivity applications. The UL94 V-0 flammability rating and 250V voltage specification support use in standard industrial and commercial electronic equipment requiring reliable multi-position interconnection.
