TE Connectivity AMP Connectors 794305-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794305-2 is a rectangular connector header designed for through-hole mounting applications. This connector features 8 positions arranged in 2 rows with a 0.165" (4.20mm) pitch, shrouded 4-wall construction, and male pin contacts with gold-plated mating surfaces. The connector is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 794305-2 connector is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Voltage rating (600VAC), operating temperature range (-55°C ~ 105°C), and contact material (Copper Alloy) must remain constant.

Mechanical Parameters: Number of positions (8), number of rows (2), pitch spacing (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), mounting type (Through Hole), shrouding configuration (Shrouded - 4 Wall), and fastening type (Locking Ramp) must be identical.

Contact Specifications: Contact type (Male Pin), contact shape (Square), contact finish on mating surface (Gold), and insulation material (Polyamide/Nylon) must match.

Environmental & Compliance: Insulation color (Natural), material flammability rating (UL94 V-2), and moisture sensitivity level (MSL 1) must be maintained.

Substitute parts are identified only when all parameters listed above are equivalent to the main part specification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-794305-2 is functionally equivalent to the obsolete 794305-2 across all critical electrical and mechanical parameters. The primary distinction between these parts is product status and regulatory compliance.

The main part (794305-2) is classified as obsolete and carries RoHS non-compliant status with undefined REACH classification. The substitute part (1-794305-2) is active in production and carries RoHS Compliant certification with REACH Unaffected status. Both parts share identical connector specifications, contact configurations, and performance ratings.

The contact finish on the post differs between the two parts: the main part uses Tin-Lead while the substitute uses Tin. This difference reflects modern manufacturing standards and regulatory requirements. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance.

For new designs and ongoing procurement, the 1-794305-2 substitute part is the appropriate selection due to its active product status, regulatory compliance, and availability. For legacy system maintenance where the exact original part specification is required, the 794305-2 remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Are the 794305-2 and 1-794305-2 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 8 positions, 2-row configuration, 0.165" (4.20mm) pitch, through-hole mounting, shrouded 4-wall construction, and locking ramp fastening. They occupy the same footprint and mate with identical receptacle connectors.

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

A: The main part uses Tin-Lead finish while the substitute uses Tin finish. Both finishes provide equivalent electrical conductivity and solder joint reliability. The Tin finish on the substitute reflects current manufacturing standards and RoHS compliance requirements.

Q: Can the 1-794305-2 be used as a direct replacement in existing assemblies designed for the 794305-2?

A: Yes. The 1-794305-2 is a direct functional equivalent with identical electrical ratings (600VAC), operating temperature range (-55°C ~ 105°C), and mechanical configuration. It is suitable for replacement in existing designs.

Q: Why is the main part classified as obsolete?

A: The 794305-2 is obsolete due to its RoHS non-compliant status and the availability of the compliant 1-794305-2 alternative. TE Connectivity has transitioned production to the active substitute part.

Q: Are there any performance differences between these connectors?

A: No. Both connectors deliver identical electrical performance, contact reliability, and environmental ratings. The differences are limited to product status, regulatory compliance, and contact post finish material.

Q: What is the significance of RoHS compliance for this connector?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations, eliminating lead and other restricted materials from the manufacturing process. The 1-794305-2 substitute meets these requirements while the original 794305-2 does not.

Q: Can both parts be used in the same production run?

A: From an electrical and mechanical standpoint, yes. However, design documentation and procurement specifications should be updated to reflect the active substitute part (1-794305-2) for consistency and regulatory compliance.

Q: What is the current inventory status for these parts?

A: The main part (794305-2) has 1081 pieces in stock. The substitute part (1-794305-2) has 1107 pieces in stock. Both are available as new original components.
