Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-794308-1 serves as a functional substitute for the obsolete 794307-2 within the AMP-DUAC series. Both connectors maintain identical mechanical and electrical specifications across pitch, row spacing, mounting configuration, shrouding design, and operating parameters.

Primary Substitution Basis:

The 1-794308-1 is an active product, addressing the obsolescence status of the 794307-2. The substitute maintains full compatibility with the core connector architecture, including through-hole mounting, solder termination, locking ramp fastening, and 600VAC voltage rating across the -55°C to 105°C operating range.

Specification Variations:

The 1-794308-1 accommodates 14 positions compared to the 12 positions of the 794307-2, with both maintaining 2-row configuration and identical pitch spacing. Contact finish specifications differ, with the substitute utilizing tin plating on mating contacts (118.1µin / 3.00µm) and tin post finish, compared to the original gold mating finish (30.0µin / 0.76µm) and tin-lead post finish.

Compliance Considerations:

The 794307-2 is classified as RoHS non-compliant, while the 1-794308-1 is REACH Affected. Both connectors maintain UL94 V-2 flammability rating and MSL 1 moisture sensitivity classification. Selection between these parts depends on regulatory requirements and compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 1-794308-1 directly replace the 794307-2 in existing designs?

A: The 1-794308-1 shares identical mechanical and electrical core specifications with the 794307-2, including pitch, row spacing, mounting type, and operating temperature range. However, the substitute provides 14 positions versus 12 positions in the original. Direct replacement is feasible only if the application design accommodates the additional 2 positions or if those positions remain unloaded.

Q: What are the differences in contact finish between these connectors?

A: The 794307-2 features gold-plated mating contacts (30.0µin / 0.76µm thickness) with tin-lead post finish. The 1-794308-1 utilizes tin-plated mating contacts (118.1µin / 3.00µm thickness) with tin post finish. Both finishes are compatible with solder termination and maintain electrical performance within the 600VAC rating.

Q: Are there compatibility concerns with mating connectors?

A: Both the 794307-2 and 1-794308-1 are headers within the AMP-DUAC series with identical pitch (0.165" / 4.20mm) and row spacing. Mating connectors designed for the AMP-DUAC series are compatible with both parts. Position count differences require verification that mating connectors accommodate the respective pin counts.

Q: What is the significance of the product status difference?

A: The 794307-2 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1-794308-1 is active, ensuring ongoing availability and manufacturing support. For new designs or long-term procurement requirements, the active substitute is the appropriate selection.

Q: How do RoHS and REACH compliance statuses affect part selection?

A: The 794307-2 is RoHS non-compliant, while the 1-794308-1 is REACH Affected. Compliance requirements vary by application and regulatory jurisdiction. Applications subject to RoHS directives require evaluation of the 1-794308-1 compliance status. Applications with no specific compliance mandates can utilize either part based on availability and design requirements.

Q: Are the operating temperature ranges identical?

A: Both the 794307-2 and 1-794308-1 operate across the identical temperature range of -55°C to 105°C. Thermal performance and reliability specifications are equivalent between the two connectors.

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

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
