Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 4-1393483-9 with the active part 5-747912-2 is based on strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility:

• Identical connector style (D-Sub) and type (Plug, Male Pins)
• Matching position count (25 positions) and row configuration (2 rows)
• Equivalent shell size and connector layout (3, DB, B)
• Identical mounting type (Free Hanging, In-Line)
• Matching termination method (Solder Cup)
• Equal current rating (3A)
• Same contact material (Brass) and finish (Gold)
• Identical dielectric material classification (Polybutylene Terephthalate, PBT)
• Same series designation (AMPLIMITE HD-20)
• Matching flange feature (Housing/Shell, Unthreaded)
• Identical contact type (Signal)
• Same moisture sensitivity level (MSL 1, Unlimited)

Compliance and Status:

• The substitute part 5-747912-2 is active and currently in production
• Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications
• The substitute part carries ROHS3 compliance certification

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-747912-2 is a direct functional equivalent to the obsolete 4-1393483-9 across all critical electrical and mechanical parameters. Selection of the substitute part is supported by the following factors:

Product Status and Availability: The substitute part maintains active production status with significantly higher inventory availability (379,020 units versus 907 units), ensuring long-term supply chain continuity.

Compliance and Certification: The substitute part carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in regulated markets. Both parts share identical export control classifications (EAR99) and tariff codes (8536.69.8000).

Electrical and Mechanical Compatibility: All critical parameters determining connector function and interchangeability are identical between the main part and substitute, including position count, shell size, termination method, current rating, and contact materials.

Operating Conditions: The substitute part operates across a temperature range of -55°C to 105°C, which encompasses the lower end of the main part's specified range (-55°C to 125°C). For applications requiring operation above 105°C, the main part specifications must be retained.

Physical Differences: The substitute part features a black housing color compared to the gray housing of the main part. The dielectric material composition differs (glass-filled PBT versus polyester-based PBT), and the substitute part specifies contact finish thickness at 8.00µin (0.203µm). These differences do not affect functional equivalence for standard D-Sub connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-747912-2 be used as a direct replacement for the 4-1393483-9 in existing designs?

A: Yes. The substitute part 5-747912-2 is electrically and mechanically equivalent to the 4-1393483-9 across all critical parameters including connector type, position count, shell size, termination method, and current rating. Both parts are 25 Position D-Sub Plugs with identical mounting and electrical specifications.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), housing color (gray versus black), dielectric material composition (polyester-based PBT versus glass-filled PBT), and operating temperature upper limit (125°C versus 105°C). The substitute part also includes specified contact finish thickness and carries ROHS3 compliance certification.

Q: Are there temperature limitations when substituting the 5-747912-2 for the 4-1393483-9?

A: The substitute part 5-747912-2 is rated for operation from -55°C to 105°C. If the application requires sustained operation above 105°C, the original part specifications must be retained or alternative components evaluated.

Q: Does the housing color difference affect connector function?

A: No. The housing color difference (gray versus black) is a cosmetic distinction and does not affect electrical performance, mechanical fit, or functional compatibility.

Q: What is the significance of the glass-filled dielectric material in the substitute part?

A: The glass-filled PBT dielectric material in the substitute part provides enhanced mechanical strength and dimensional stability compared to polyester-based formulations. This material composition is standard in current production D-Sub connectors and does not affect electrical performance or compatibility.

Q: Is the substitute part RoHS compliant?

A: Yes. The substitute part 5-747912-2 carries ROHS3 compliance certification. The original part status is listed as not applicable for RoHS compliance.

Q: What is the packaging difference between these parts?

A: The main part packaging is not specified in available documentation. The substitute part 5-747912-2 is supplied in tray packaging, which is standard for high-volume production applications.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 4-1393483-9 and 5-747912-2 are manufactured by TE Connectivity AMP Connectors and are part of the AMPLIMITE HD-20 series.

Q: What is the inventory status for each part?

A: The original part 4-1393483-9 has 907 units in stock. The substitute part 5-747912-2 has 379,020 units in stock, providing significantly greater availability for new production and field service requirements.

Q: Are the contact finish specifications equivalent?

A: Both parts feature gold-plated contacts. The substitute part specifies contact finish thickness at 8.00µin (0.203µm). The original part does not include finish thickness specification. Both finishes meet standard D-Sub connector contact requirements.
