TE Connectivity AMP Connectors 746612-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746612-3 is a 16-position ribbon cable DIP header connector with IDC termination, designed for through-hole mounting applications. This connector features a vertical orientation with dual-row configuration and gold-plated contacts suitable for 28 AWG stranded or 26-30 AWG solid wire gauges.

The 746612-3 carries an obsolete product status, which necessitates identification of active equivalent parts to ensure continued availability and supply chain continuity for new designs and production requirements. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 746612-3 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish direct interchangeability:

Critical Matching Parameters:

• Connector type: Ribbon Cable, DIP Header
• Position count: 16 positions
• Row configuration: 2 rows
• Cable pitch: 0.050" (1.27mm)
• Board-side pitch: 0.100" (2.54mm)
• Row spacing: 0.300" (7.62mm)
• Mounting method: Through Hole
• Termination method: IDC
• Wire gauge compatibility: 28 AWG Stranded; 26-30 AWG Solid
• Contact finish: Gold at 15.0µin (0.38µm)
• Color: Black
• Feed-through capability: Required

Substitute parts must satisfy all parameters listed above without deviation. Parts meeting these specifications are classified as direct equivalents and may be used interchangeably in applications originally designed for the 746612-3.

Parameter Comparison

Engineering Selection Recommendations

The 5746612-3 is the direct functional equivalent to the obsolete 746612-3. All electrical and mechanical parameters are identical, ensuring pin-for-pin and footprint compatibility.

Product Status Consideration: The 746612-3 is classified as obsolete, while the 5746612-3 maintains active product status. Active status ensures ongoing manufacturer support, availability, and supply chain reliability for current and future production requirements.

Compliance Consideration: The 5746612-3 is RoHS compliant, whereas the 746612-3 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 5746612-3 is the appropriate selection. Both parts maintain identical MSL ratings and ECCN classifications.

Inventory Availability: The 5746612-3 is currently available with 1025 pieces in stock, compared to 730 pieces of the obsolete 746612-3. Selection of the active equivalent ensures access to sustained inventory levels.

For new designs and production applications, the 5746612-3 is the recommended selection. For legacy system maintenance requiring exact part matching, the 746612-3 remains functionally equivalent where RoHS compliance is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the 5746612-3 be used as a direct replacement for the 746612-3 in existing designs?

A: Yes. The 5746612-3 is electrically and mechanically identical to the 746612-3. All connector dimensions, pitch specifications, contact configurations, and wire gauge compatibility are equivalent. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the 746612-3 and 5746612-3?

A: The primary differences are product status and RoHS compliance. The 746612-3 is obsolete and RoHS non-compliant. The 5746612-3 is active and RoHS compliant. All functional specifications are identical.

Q: Are there any compatibility concerns when substituting the 5746612-3 for the 746612-3?

A: No compatibility concerns exist. Both connectors feature identical board-side pitch (0.100"), cable pitch (0.050"), row spacing (0.300"), and through-hole mounting configuration. Ribbon cable assemblies designed for the 746612-3 are directly compatible with the 5746612-3.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts maintain identical contact finish specifications (gold at 15.0µin) and electrical characteristics.

Q: What wire gauges are compatible with both connectors?

A: Both the 746612-3 and 5746612-3 accept 28 AWG stranded wire and 26-30 AWG solid wire through IDC termination. Wire gauge compatibility is identical between the two parts.

Q: Is the 5746612-3 available in the same packaging as the 746612-3?

A: Both parts are supplied without specified packaging designation in the provided specifications. Contact the manufacturer for detailed packaging and shipping container information.

Q: Why should I select the 5746612-3 over the 746612-3 for new production?

A: The 5746612-3 is the active equivalent with sustained manufacturer support and supply chain availability. Obsolete parts carry risk of future unavailability. For new designs and ongoing production, the 5746612-3 ensures long-term component access and compliance with modern regulatory requirements.
