TE Connectivity AMP Connectors 794470-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794470-1 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 12 positions arranged in 2 rows, utilizing a 0.165" (4.20mm) pitch configuration. The connector is classified as a shrouded 4-wall header with male pin contacts and solder termination, suitable for board-to-board or cable interconnection.

The 794470-1 carries an obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Active substitute parts with identical electrical and mechanical specifications are available to ensure continuity in component sourcing and system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794470-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

Electrical Parameters:

• Contact type (Male Pin)
• Number of positions (12)
• Row configuration (2 rows)
• Mating pitch (0.165" / 4.20mm)
• Row spacing (0.165" / 4.20mm)
• Voltage rating (600VAC)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Parameters:

• Connector type (Header)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation height (0.504" / 12.80mm)
• Contact shape (Square)

Material & Compliance Parameters:

• Insulation material (Polyamide / Nylon)
• Contact material (Copper Alloy)
• Flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

The substitute part 1-794470-1 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-794470-1 is a direct functional equivalent to the obsolete 794470-1 across all critical electrical and mechanical parameters. Both parts are manufactured by TE Connectivity within the AMP-DUAC series and share identical connector specifications, contact configurations, and performance ratings.

Primary Distinction - Contact Finish: The main part (794470-1) features Tin-Lead contact finish, while the substitute part (1-794470-1) features Tin contact finish. Both finishes provide equivalent electrical performance and reliability within the specified operating parameters.

Compliance Advantage: The substitute part 1-794470-1 carries active product status and is RoHS Compliant with REACH Unaffected designation. The main part 794470-1 is classified as obsolete and RoHS non-compliant. For new designs and ongoing procurement, the substitute part 1-794470-1 is the appropriate selection.

Interchangeability: The 1-794470-1 is a direct replacement for the 794470-1 in all applications requiring a 12-position, 2-row rectangular connector header with 0.165" pitch, through-hole solder termination, and shrouded 4-wall configuration. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1-794470-1 substitute directly for the 794470-1 without design changes?

A: Yes. The 1-794470-1 is a direct functional equivalent with identical electrical and mechanical specifications. No PCB layout modifications or connector interface changes are required.

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

A: Both finishes provide equivalent electrical conductivity and contact reliability within the specified operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC). The Tin finish on the substitute part meets modern RoHS compliance requirements.

Q: Why is the main part 794470-1 marked as obsolete?

A: The 794470-1 has been superseded by the 1-794470-1, which maintains identical functionality while offering improved compliance status (RoHS Compliant) and active product availability.

Q: Are there any inventory or lead time differences between these parts?

A: The main part 794470-1 has 906 pieces in stock, while the substitute part 1-794470-1 has 1064 pieces in stock. Both are available as new original components.

Q: What is the significance of the RoHS compliance difference?

A: RoHS Compliance indicates the part meets Restriction of Hazardous Substances regulations. The substitute part 1-794470-1 is RoHS Compliant, making it suitable for applications and markets with RoHS requirements. The main part 794470-1 is RoHS non-compliant due to its Tin-Lead contact finish.

Q: Can both parts be used interchangeably in existing designs?

A: Yes. Both parts share identical connector geometry, pitch, row spacing, mounting configuration, and electrical ratings. Existing designs using the 794470-1 can transition to the 1-794470-1 without modification.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the main part and substitute part carry this designation.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -55°C to 105°C and maintain the same UL94 V-0 flammability rating.
