Key Parameters

Substitute Part Grouping Explanation

Substitution of the 747303-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1, DE/E)
• Contact material (Phosphor Bronze)
• Contact finish (Gold, 30.0µin thickness)
• Current rating (1.25A)
• Operating temperature range (-55°C to 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Termination method (IDC, Ribbon Cable)
• Shell material and finish (Steel, Tin Plated)
• Flange feature (Housing/Shell, Unthreaded)
• Dielectric material (Thermoplastic)
• Material flammability rating (UL94 V-0)

Environmental & Regulatory Parameters:

• Moisture sensitivity level (1, Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.4051)

The substitute part 1658612-4 maintains full equivalence across all critical parameters, with the primary distinction being product status (active versus obsolete) and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The TE Connectivity 1658612-4 serves as a direct functional equivalent to the 747303-4 across all electrical and mechanical parameters. Both connectors are identical in connector style, pin configuration, termination method, shell construction, contact materials, and operating specifications.

Regulatory and Compliance Considerations:

The 1658612-4 is classified as an active product with ROHS3 compliance and REACH Unaffected status, whereas the 747303-4 is obsolete and RoHS non-compliant. For new designs or systems subject to regulatory compliance requirements, the 1658612-4 is the appropriate selection. For legacy system maintenance where the original 747303-4 remains in service, the 1658612-4 provides functional continuity with improved compliance posture.

Inventory and Availability:

The 1658612-4 is available in bulk packaging with 1490 pieces in current stock, compared to the 747303-4 with 1011 pieces in stock. The active product status of the 1658612-4 ensures continued availability for future procurement.

Frequently Asked Questions (FAQ)

Q: Can the 1658612-4 be used as a direct replacement for the 747303-4 in existing assemblies?

A: Yes. The 1658612-4 is electrically and mechanically equivalent to the 747303-4. Both connectors share identical pin counts (9 positions), shell sizes (DE/E), contact materials (Phosphor Bronze with gold finish), current ratings (1.25A), operating temperature ranges (-55°C to 105°C), and IDC ribbon cable termination specifications. Physical form factor and mounting configuration are identical.

Q: What is the difference in RoHS compliance between these two parts?

A: The 747303-4 is RoHS non-compliant with vendor-undefined REACH status. The 1658612-4 is ROHS3 compliant and REACH Unaffected. For applications subject to RoHS or REACH regulations, the 1658612-4 is the required selection.

Q: Are there packaging differences between the 747303-4 and 1658612-4?

A: The 747303-4 packaging specification is not provided in the technical data. The 1658612-4 is supplied in bulk packaging. Both parts are identical in form and function; packaging differences do not affect connector performance or compatibility.

Q: Why is the 747303-4 classified as obsolete?

A: The 747303-4 is an obsolete product from the AMPLIMITE HDF-20 series. The 1658612-4 represents the current active equivalent within the same series, offering identical functionality with updated compliance certifications.

Q: Can the 1658612-4 be used in applications originally designed for the 747303-4?

A: Yes. The 1658612-4 maintains full electrical and mechanical compatibility with the 747303-4 across all specified parameters. No design modifications or recertification is required for direct substitution in existing applications.

Q: What wire gauge compatibility does the 1658612-4 support?

A: The 1658612-4 supports 26-28 AWG wire gauge in both stranded and solid configurations for IDC ribbon cable termination.
