TE Connectivity AMP Connectors 794472-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794472-2 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 24 positions arranged in 2 rows, utilizing a 0.165" (4.20mm) pitch configuration. The connector is classified as a shrouded 4-wall header with board lock functionality, suitable for board-to-board or cable interconnection.

The 794472-2 carries an obsolete product status, which necessitates identification of active equivalent alternatives to ensure continued design support and component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 794472-2 rectangular connector header is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Contact type (male pin), pitch configuration (0.165" / 4.20mm mating pitch), row spacing (0.165" / 4.20mm), number of positions (24), number of rows (2), contact material (copper alloy), contact finish on mating surface (gold), voltage rating (600VAC), and operating temperature range (-55°C ~ 105°C).

Mechanical Parameters: Connector type (header), shrouding configuration (shrouded 4-wall), mounting method (through hole), termination type (solder), fastening mechanism (locking ramp), insulation material (polyamide/nylon), insulation height (0.504" / 12.80mm), contact shape (square), and material flammability rating (UL94 V-0).

Compliance Parameters: Series designation (AMP-DUAC), base product number (794472), and ECCN/HTSUS classifications.

Substitutes are grouped based on active product status and regulatory compliance improvements, specifically RoHS and REACH compliance status, while maintaining full backward compatibility with the original 794472-2 specification.

Parameter Comparison

Engineering Selection Recommendations

The 1-794472-2 substitute part is a direct functional equivalent to the obsolete 794472-2 connector header. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, shrouding, mounting method, and operating characteristics.

The primary distinction between the original and substitute part is product status and regulatory compliance. The 794472-2 is classified as obsolete with RoHS non-compliant status and vendor-undefined REACH compliance. The 1-794472-2 is an active product with ROHS3 compliance certification and REACH unaffected status, indicating improved alignment with current regulatory requirements.

The contact finish on the post differs between the two parts: the original 794472-2 uses tin-lead finish, while the 1-794472-2 uses tin finish. This variation reflects the transition away from lead-based materials in electronic components and is compatible with standard solder reflow processes.

For new designs and production applications, the 1-794472-2 is the appropriate selection due to its active product status and improved compliance posture. For legacy system maintenance where the original 794472-2 is specified, the 1-794472-2 provides full backward compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are the 794472-2 and 1-794472-2 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shrouding configuration (4-wall), mounting type (through hole), insulation height (0.504" / 12.80mm), contact shape (square), and fastening mechanism (locking ramp). They are directly interchangeable in board-to-board and cable applications.

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

A: The original 794472-2 features tin-lead finish on the post, while the 1-794472-2 uses tin finish. Both finishes are compatible with standard solder reflow processes. The tin finish in the substitute part reflects compliance with lead-free manufacturing standards.

Q: Are the electrical specifications identical between 794472-2 and 1-794472-2?

A: Yes. Both parts maintain identical electrical specifications: 24 positions in 2 rows, 0.165" (4.20mm) pitch, male pin contacts with gold mating finish, 600VAC voltage rating, and -55°C ~ 105°C operating temperature range.

Q: Why is the 794472-2 listed as obsolete?

A: The 794472-2 has been superseded by the 1-794472-2, which offers improved regulatory compliance including ROHS3 certification and REACH unaffected status. TE Connectivity maintains the 1-794472-2 as the active product for this connector configuration.

Q: Can I use the 1-794472-2 as a direct replacement in existing designs?

A: Yes. The 1-794472-2 is a direct replacement for the 794472-2 with no design modifications required. All electrical, mechanical, and dimensional specifications are identical, ensuring full compatibility with existing PCB layouts and mating connectors.

Q: What is the significance of the ROHS3 compliance on the 1-794472-2?

A: ROHS3 compliance indicates that the 1-794472-2 meets the Restriction of Hazardous Substances Directive requirements, specifically the restriction on lead and other hazardous materials. This is a regulatory requirement for products sold in the European Union and many other markets.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 794472-2 and 1-794472-2 operate across the identical temperature range of -55°C to 105°C, ensuring equivalent thermal performance in all environmental conditions.

Q: What is the contact material composition for both connectors?

A: Both connectors use copper alloy as the contact material with gold plating on the mating surface (30.0µin / 0.76µm thickness) to ensure reliable electrical contact and corrosion resistance.
