Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745171-2 is determined by strict equivalence across all critical mechanical and electrical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Accessory Type: Two Piece Backshell
• Number of Positions: 9
• Compatible Shell Size: E
• Compatible D-Sub Size: 9pos and HD15pos
• Cable Type: Round
• Cable Exit Angle: 180°
• Shielding: Shielded
• Material Composition: Metal, Zinc Alloy
• Plating: Nickel over Copper
• Color: Silver
• Series: AMPLIMITE

The substitute part 5745171-2 meets all of these criteria and is therefore classified as a direct equivalent. Differences in product status, compliance certifications, and packaging do not affect functional interchangeability in the connector assembly.

Parameter Comparison

Engineering Selection Recommendations

The 745171-2 is classified as Obsolete, indicating that TE Connectivity no longer manufactures or supports this part number. The substitute part 5745171-2 provides functional equivalence with the following additional considerations:

Product Status: The 5745171-2 carries Active product status, ensuring ongoing availability and manufacturer support for new applications and replenishment orders.

Compliance Certifications: The 5745171-2 is RoHS Compliant, whereas the 745171-2 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 5745171-2 is the appropriate selection. The 5745171-2 is REACH Affected, indicating compliance with REACH regulatory requirements.

Mechanical and Electrical Equivalence: All functional parameters remain identical between the two part numbers. The 5745171-2 includes mating screws (4-40) and strain relief hardware, providing equivalent assembly functionality.

Packaging: The 5745171-2 is supplied in Bulk packaging, which may differ from the original packaging specification of the 745171-2.

For new designs, maintenance applications, and production requiring regulatory compliance, the 5745171-2 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the 5745171-2 be used as a direct replacement for the 745171-2 in existing assemblies?

A: Yes. The 5745171-2 is mechanically and electrically equivalent to the 745171-2. All critical parameters including connector position count, shell size compatibility, cable exit angle, shielding, material composition, and plating are identical. The parts are functionally interchangeable in D-Sub connector assemblies.

Q: What is the difference between the 745171-2 and 5745171-2?

A: The primary differences are product status and regulatory compliance. The 745171-2 is Obsolete and RoHS non-compliant, while the 5745171-2 is Active and RoHS Compliant. The 5745171-2 also includes mating screws (4-40) and strain relief hardware. All mechanical and electrical specifications are identical.

Q: Why is the 745171-2 listed as Obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued manufacturing of this part number. The 5745171-2 serves as the active equivalent and is the recommended part for ongoing procurement.

Q: Does the 5745171-2 work with 9-position and HD15-position D-Sub connectors?

A: Yes. The 5745171-2 is compatible with both 9-position and HD15-position D-Sub connectors, as specified by the Compatible D-Sub Size parameter of "9pos and HD15pos."

Q: What is the cable exit angle for these backshells?

A: Both the 745171-2 and 5745171-2 feature a 180° cable exit angle, meaning the cable exits in a straight line opposite to the connector mating face.

Q: Are these backshells shielded?

A: Yes. Both parts are shielded backshells constructed from metal (zinc alloy) with nickel over copper plating, providing electromagnetic shielding for the connector assembly.

Q: What is the shell size designation "E"?

A: Shell Size E is the standard designation for 9-position D-Sub connectors in the AMPLIMITE series. This size is compatible with both standard 9-position and HD15-position D-Sub connector configurations.

Q: Is the 5745171-2 RoHS compliant?

A: Yes. The 5745171-2 is RoHS Compliant, meeting the Restriction of Hazardous Substances directive requirements. The original 745171-2 is RoHS non-compliant.

Q: What hardware is included with the 5745171-2?

A: The 5745171-2 includes assembly hardware, cable clamp, mating screws (4-40), and strain relief components for complete backshell assembly.
