Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 747100-5 is based on strict equivalence across the following critical parameters:

• Number of Positions: 37 positions (mandatory match)
• Compatible Shell Size: C (mandatory match)
• Compatible D-Sub Size: 37pos and HD62pos (mandatory match)
• Cable Exit Angle: 180° (mandatory match)
• Shielding Configuration: Shielded (mandatory match)
• Plating Specification: Nickel over Copper (mandatory match)
• Mating Hardware: Mating Screws 4-40 (mandatory match)
• Color: Silver (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

The substitute part 5748677-4 meets all critical electrical and mechanical parameters required for direct substitution. Both parts belong to the AMPLIMITE HD-20 series and maintain identical connector compatibility and functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5748677-4 is a direct functional equivalent to the obsolete 747100-5. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 747100-5 is classified as obsolete, while the 5748677-4 maintains active product status with confirmed inventory availability (1381 pieces in stock versus 843 pieces for the obsolete part). Active status ensures continued supply chain access and manufacturer support.

Regulatory Compliance: The 5748677-4 is RoHS compliant, whereas the 747100-5 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Material Specification: The substitute part utilizes Acrylonitrile Butadiene Styrene (ABS) as the primary material, compared to the generic thermoplastic specification of the main part. Both materials are compatible with the connector's functional requirements and environmental specifications (MSL 1).

Hardware Configuration: The main part includes strain relief hardware, while the substitute includes grommets. Both configurations provide equivalent mechanical support and cable protection for the 180° cable exit application.

Electrical and Mechanical Compatibility: All critical parameters—connector position count, shell size, D-Sub compatibility, cable exit angle, shielding, plating, and mating hardware—are identical between the two parts, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 5748677-4 be used as a direct replacement for the 747100-5 in existing designs?

A: Yes. The 5748677-4 meets all critical electrical and mechanical specifications of the 747100-5, including connector position count (37), shell size (C), D-Sub compatibility (37pos and HD62pos), cable exit angle (180°), shielding configuration, plating specification (Nickel over Copper), and mating hardware (4-40 screws). Direct substitution is supported without design modification.

Q: What is the difference in material composition between the two parts?

A: The 747100-5 uses a generic thermoplastic material, while the 5748677-4 specifies Acrylonitrile Butadiene Styrene (ABS). Both materials are compatible with the connector's functional and environmental requirements. ABS provides enhanced material specification documentation and consistency.

Q: Are there differences in hardware configuration?

A: The 747100-5 includes strain relief hardware, while the 5748677-4 includes grommets. Both configurations provide equivalent mechanical support and cable protection for the 180° cable exit application. Selection between these hardware types depends on specific cable management requirements in the end application.

Q: Does the substitute part meet RoHS compliance requirements?

A: Yes. The 5748677-4 is RoHS compliant, whereas the 747100-5 is RoHS non-compliant. Applications requiring RoHS compliance should specify the 5748677-4.

Q: What is the inventory status of each part?

A: The 747100-5 (obsolete) has 843 pieces in stock. The 5748677-4 (active) has 1381 pieces in stock. The active status and higher inventory of the substitute part provide improved supply chain reliability.

Q: Are the export control classifications identical?

A: Yes. Both parts carry the same ECCN classification (EAR99) and HTSUS code (8538.90.8180), ensuring equivalent export control treatment.

Q: What is the packaging difference between the two parts?

A: The 747100-5 packaging is not specified in the available data. The 5748677-4 is supplied in bulk packaging. Confirm packaging requirements with the supplier for specific application needs.
