Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745919-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 15
• Compatible Shell Size: A
• Compatible D-Sub Size: 15pos and HD26pos
• Cable Exit Angle: 180°
• Shielding: Shielded
• Primary Material: Metal, Zinc Alloy
• Plating: Nickel over Copper
• Accessory Type: Two Piece Backshell
• Cable Type: Round
• Series: AMPLIMITE HD-20

The substitute part 5745919-2 meets all mandatory matching parameters and is therefore classified as a direct equivalent. The primary distinction between the main part and its substitute is product status: the 745919-2 is obsolete, while 5745919-2 is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The 5745919-2 is the direct equivalent substitute for the obsolete 745919-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 5745919-2 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. The 745919-2 is obsolete and no longer manufactured.

Compliance Status: The 5745919-2 is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components. The 745919-2 is RoHS non-compliant and does not meet modern regulatory standards.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The 5745919-2 provides identical performance characteristics, mechanical fit, and electrical properties as the original 745919-2.

Availability: The 5745919-2 is available in production quantities (1032 pcs in stock) with bulk packaging, supporting both new design implementation and field service requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5745919-2 be used as a direct replacement for the 745919-2 in existing designs?

A: Yes. The 5745919-2 is a direct functional equivalent with identical electrical and mechanical specifications. All critical parameters including position count, shell size, cable exit angle, shielding, material composition, and plating are identical.

Q: What is the primary difference between these two parts?

A: The 745919-2 is obsolete and RoHS non-compliant, while the 5745919-2 is an active product that meets ROHS3 compliance standards. The 5745919-2 is the current production equivalent.

Q: Are there any compatibility concerns when substituting the 5745919-2 for the 745919-2?

A: No compatibility concerns exist. Both parts are compatible with 15-position and HD26-position D-Sub connectors with Shell Size A. The 180° cable exit angle, shielding configuration, and mechanical interface are identical.

Q: What is the difference in packaging between these parts?

A: The 745919-2 packaging is not specified in available documentation. The 5745919-2 is supplied in bulk packaging, suitable for production assembly and field service applications.

Q: Does the RoHS3 compliance of the 5745919-2 affect its electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The 5745919-2 maintains identical electrical characteristics to the 745919-2.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 745919-2 and 5745919-2 are manufactured by TE Connectivity AMP Connectors and are part of the AMPLIMITE HD-20 series.

Q: What is the cable type compatibility for these backshells?

A: Both parts are designed for round cable types with 180° cable exit configuration.
