Substitute Part Grouping Explanation

Substitution between the 747905-4 and 5-747905-2 is based on electrical and mechanical parameter equivalence within the D-Sub receptacle connector category. Both parts maintain identical specifications 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)
• Voltage rating (250V)
• Current rating (3A)
• Contact material (Brass)
• Contact finish (Gold, Flash thickness)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Termination method (Solder Cup)
• Flange feature (Housing/Shell, Unthreaded)
• Dielectric material (PBT, Glass Filled)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)

Differentiating Parameters:

• Shell material finish: 747905-4 uses Blue Zinc Plated; 5-747905-2 uses Tin Plated
• Product status: 747905-4 is Obsolete; 5-747905-2 is Active
• RoHS compliance: 747905-4 is non-compliant; 5-747905-2 is ROHS3 compliant
• Packaging: 747905-4 has no specified packaging; 5-747905-2 is supplied in Tray
• Inventory availability: 747905-4 has 700 pcs; 5-747905-2 has 473,277 pcs

Parameter Comparison

Engineering Selection Recommendations

The 5-747905-2 serves as the direct active equivalent to the obsolete 747905-4. Selection between these parts is determined by product lifecycle and regulatory requirements:

Use 747905-4 when:

• Existing inventory of the obsolete part is available and acceptable for the application
• Legacy system maintenance requires exact original part matching
• RoHS compliance is not a requirement for the end application

Use 5-747905-2 when:

• New production designs require active, in-stock components
• RoHS3 compliance is mandated by customer specifications or regulatory standards
• Long-term supply chain continuity is required
• Tray packaging is compatible with assembly processes

Both parts maintain identical electrical and mechanical performance characteristics. The shell material finish difference (Blue Zinc Plated versus Tin Plated) does not affect electrical function but may influence corrosion resistance in specific environmental conditions. The ROHS3 compliance status of 5-747905-2 makes it the preferred choice for applications subject to European Union Restriction of Hazardous Substances regulations.

Frequently Asked Questions (FAQ)

Q: Are the 747905-4 and 5-747905-2 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including voltage rating (250V), current rating (3A), contact material (Brass with Gold flash finish), and operating temperature range (-55°C ~ 105°C). They are electrically interchangeable in all applications.

Q: What is the difference between Blue Zinc Plated and Tin Plated shell finishes?

A: Both finishes provide corrosion protection to the steel shell. Blue Zinc Plated and Tin Plated are different surface treatment methods. The choice between them depends on environmental exposure and specific application requirements. Both finishes are compatible with the same mating connectors.

Q: Why is the 747905-4 listed as obsolete?

A: The 747905-4 has been superseded by the 5-747905-2 in the product line. The 5-747905-2 offers improved compliance status (ROHS3) and maintains active production and inventory support.

Q: Can I use 5-747905-2 as a direct replacement for 747905-4 in existing assemblies?

A: Yes. The 5-747905-2 is mechanically and electrically compatible with the 747905-4. Both connectors share identical connector style, pin count, mounting type, termination method, and performance ratings. The parts are directly substitutable.

Q: What does ROHS3 compliance mean for the 5-747905-2?

A: ROHS3 compliance indicates that the 5-747905-2 meets the European Union Restriction of Hazardous Substances Directive (RoHS 3 / Directive 2011/65/EU). This certification restricts the use of specific hazardous materials in electrical and electronic equipment. The 747905-4 does not carry this certification.

Q: Are there packaging differences between these parts?

A: Yes. The 747905-4 has no specified packaging designation, while the 5-747905-2 is supplied in Tray packaging. Tray packaging is standard for high-volume assembly operations and is compatible with automated pick-and-place equipment.

Q: What is the inventory status for each part?

A: The 747905-4 has limited inventory (700 pcs). The 5-747905-2 has substantial inventory availability (473,277 pcs), making it the preferred choice for new production and ongoing supply requirements.

Q: Do both connectors support the same solder cup termination process?

A: Yes. Both the 747905-4 and 5-747905-2 use solder cup termination. The solder cup design and dimensions are identical, allowing the same soldering procedures and equipment to be used for both parts.

Q: What is the shell size designation "1 (DE, E)" for these connectors?

A: Shell size 1 with DE and E layout designations refers to the standard D-Sub connector shell size used for 9-position configurations. This is the most common D-Sub shell size and is compatible with standard D-Sub mating connectors and backshells.
