Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Mounting type (Free Hanging, In-Line)
• Termination capability (IDC, Discrete Wire)
• Flange feature (Cable Side, Male Jackscrew 4-40)
• Wire gauge compatibility (22-26 AWG)
• Voltage rating (250V)
• Operating temperature range (-55°C ~ 105°C)
• Shell material and finish (Steel, Tin Plated)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)
• Flammability rating (UL94 V-0)

All substitute parts listed maintain identical specifications across these parameters, ensuring mechanical and electrical interchangeability within the AMPLIMITE HDE-20 series.

Engineering Selection Recommendations

For New Designs and Active Production:

The 1-747944-5 is the primary recommended substitute for the obsolete 747944-5. This part maintains full electrical and mechanical equivalence while offering superior supply chain availability (64,420 units in stock) and active product status. The 1-747944-5 is ROHS3 compliant, meeting current environmental and regulatory requirements for new production applications.

For Legacy System Support:

The 1-747944-6 provides an alternative substitute with equivalent specifications and active product status. This part is also ROHS3 compliant and maintains full interchangeability with the original 747944-5. The 1-747944-6 is available in bulk packaging with 1,985 units in stock.

Compliance Considerations:

Both substitute parts (1-747944-5 and 1-747944-6) are ROHS3 compliant, whereas the original 747944-5 is RoHS non-compliant. For applications subject to RoHS regulations, either substitute part satisfies compliance requirements. The original part remains suitable for legacy systems where RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 1-747944-5 and 1-747944-6 mechanically interchangeable with the original 747944-5?

A: Yes. Both substitute parts maintain identical mechanical specifications including connector style, pin configuration (9-position, 2-row), shell size (DE/E), mounting type (free hanging in-line), and flange design (cable-side male jackscrew 4-40). Direct mechanical substitution is supported.

Q: Are the substitute parts electrically equivalent to the original 747944-5?

A: Yes. Both substitute parts maintain identical electrical specifications including voltage rating (250V), operating temperature range (-55°C to 105°C), contact material (phosphor bronze), contact finish (gold), and termination capability (IDC and discrete wire). Electrical interchangeability is confirmed.

Q: What is the difference between 1-747944-5 and 1-747944-6?

A: Both parts are electrically and mechanically equivalent. The primary differences are packaging format (bulk for both) and inventory availability. The 1-747944-5 has significantly higher stock levels (64,420 units) compared to 1-747944-6 (1,985 units). Both are ROHS3 compliant and active products.

Q: Why is the original 747944-5 marked as obsolete?

A: The 747944-5 is classified as obsolete by the manufacturer. The substitute parts 1-747944-5 and 1-747944-6 represent the current active product offerings within the AMPLIMITE HDE-20 series and are recommended for all new applications and ongoing production.

Q: Are there RoHS compliance differences between the original and substitute parts?

A: Yes. The original 747944-5 is RoHS non-compliant. Both substitute parts (1-747944-5 and 1-747944-6) are ROHS3 compliant. For applications requiring RoHS compliance, either substitute part is suitable.

Q: Can the substitute parts be used in legacy systems designed for the 747944-5?

A: Yes. The substitute parts maintain full mechanical and electrical equivalence with the original 747944-5. They are suitable for retrofit applications and legacy system support without design modification.

Q: What wire gauges are supported by these connectors?

A: All parts in this series support wire gauges from 22 to 26 AWG for both IDC and discrete wire termination methods.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. Refer to the specific wire gauge used in your application for precise current rating specifications.
