TE Connectivity AMP Connectors 794631-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794631-4 is a rectangular connector header designed for through-hole mounting applications. This connector is a vertical 4-position header with 3.00mm pitch spacing, part of the Micro MATE-N-LOK series. The component features shrouded 4-wall construction with male pin contacts and is rated for 250V operation across a temperature range of -40°C to 105°C.

The 794631-4 carries an obsolete product status, making it necessary to identify equivalent substitute components for ongoing design support and procurement. The primary substitute maintains full electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The 794631-4 and its substitute 3-794631-4 share identical specifications in the following critical areas:

Electrical Parameters: Voltage rating of 250V, operating temperature range of -40°C to 105°C, and current rating that varies by wire gauge ensure electrical compatibility.

Mechanical Parameters: Both connectors maintain 4 positions arranged in 2 rows with 0.118" (3.00mm) pitch spacing in both mating and row spacing dimensions. Through-hole mounting type, shrouded 4-wall construction, and square contact shape are identical across both parts.

Contact Configuration: Male pin contact type with brass material, gold-plated mating surface (15.0µin thickness), and tin or tin-lead post finish (100.0µin thickness) provide equivalent contact performance.

Insulation Specifications: Polyamide (PA) nylon insulation material with UL94 V-0 flammability rating and black insulation color are consistent between both parts.

The substitute relationship is based exclusively on these matching parameters. No additional technical criteria are applied to the substitution determination.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-794631-4 is the direct equivalent for the obsolete 794631-4. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 794631-4 is classified as obsolete, while 3-794631-4 maintains active product status. This distinction is significant for long-term supply chain planning and component availability.

Compliance Certifications: The substitute part 3-794631-4 carries ROHS3 compliance certification, whereas the main part 794631-4 is RoHS non-compliant. The substitute also carries REACH Unaffected status compared to the vendor-undefined status of the main part. These compliance improvements make 3-794631-4 the preferred selection for new designs and ongoing production.

Contact Finish Difference: The primary distinction between the two parts is the post contact finish. The 794631-4 features tin-lead plating, while 3-794631-4 uses tin plating. Both maintain the same thickness specification of 100.0µin (2.54µm) and provide equivalent electrical performance. The tin finish in the substitute part aligns with modern lead-free manufacturing standards.

Packaging: The substitute part 3-794631-4 is supplied in tray packaging, which may differ from the original part's packaging configuration. Packaging selection should be evaluated based on assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are 794631-4 and 3-794631-4 electrically interchangeable?

A: Yes. Both connectors maintain identical voltage ratings (250V), operating temperature ranges (-40°C to 105°C), and current rating specifications (varies by wire gauge). The electrical performance is equivalent across all specified parameters.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both finishes provide equivalent electrical conductivity and contact performance at the specified thickness of 100.0µin (2.54µm). The tin finish in the substitute part aligns with lead-free manufacturing standards and modern environmental regulations. The functional performance in the application remains unchanged.

Q: Can 794631-4 be replaced with 3-794631-4 in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, pitch spacing (0.118" / 3.00mm), mounting type (through-hole), and shrouding configuration (shrouded 4-wall). PCB footprints and mating connector compatibility are preserved.

Q: Why is the RoHS compliance status different between the two parts?

A: The 794631-4 is classified as RoHS non-compliant, while 3-794631-4 is ROHS3 compliant. This reflects the product development timeline and manufacturing standards applied to each part. For applications requiring RoHS compliance, 3-794631-4 is the appropriate selection.

Q: Does packaging affect the technical compatibility of these connectors?

A: No. Packaging format (tray versus other configurations) does not affect electrical or mechanical compatibility. Packaging selection is determined by assembly process requirements, storage conditions, and inventory management practices rather than technical performance.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both 794631-4 and 3-794631-4 are rated for general-purpose applications with identical operating specifications, temperature ranges, and voltage ratings.

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

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