Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745036-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector style (D-Sub)
• Connector type (Plug for Male Contacts)
• Number of positions (25)
• Number of rows (2)
• Shell size and connector layout (3, DB, B)
• Mounting type (Free Hanging, In-Line)
• Flange feature (Cable Side with 4-40 mounting)

Material and Physical Parameters:

• Shell material and finish (Steel, Tin Plated)
• Dielectric material composition
• Color (Black)
• Grounding indents feature

Electrical and Environmental Parameters:

• Contact type (Signal)
• Moisture Sensitivity Level (MSL 1)

The substitute part 5745036-2 maintains full equivalence across all mechanical, material, and electrical parameters. The primary distinction between the main part and its substitute is product status (obsolete versus active) and regulatory compliance (RoHS non-compliant versus ROHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

The 5745036-2 is the direct active equivalent for the obsolete 745036-2. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The 745036-2 is classified as obsolete, while the 5745036-2 maintains active product status with TE Connectivity AMP Connectors. Active status ensures continued availability, technical support, and manufacturing consistency.

Regulatory Compliance: The 5745036-2 is ROHS3 compliant and REACH unaffected, whereas the 745036-2 is RoHS non-compliant with undefined REACH status. For applications subject to regulatory requirements in the European Union and other jurisdictions enforcing RoHS directives, the 5745036-2 satisfies compliance obligations.

Mechanical and Electrical Equivalence: Both parts maintain identical specifications across all critical parameters including connector configuration (25-position D-Sub plug), shell size (3, DB, B), mounting type (free hanging, in-line), flange design (cable side, 4-40), and contact type (signal). The grounding indents feature is present in both variants.

Material Specifications: Both parts feature steel shells with tin plating and black color. The 5745036-2 specifies shell finish thickness at 200µin (5.08µm), providing documented coating consistency. Dielectric materials differ in specification format (polyamide/nylon glass-filled versus thermoplastic designation), but both provide equivalent electrical insulation properties for signal contact applications.

Environmental Ratings: Both parts carry MSL 1 (unlimited moisture sensitivity), indicating no moisture-related handling restrictions during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 5745036-2 be used as a direct replacement for the 745036-2 in existing designs?

A: Yes. The 5745036-2 is mechanically and electrically equivalent to the 745036-2 across all critical parameters including connector style, position count, shell size, mounting configuration, and contact type. The parts are interchangeable for applications where the connector housing plug functions identically within the AMPLIMITE HDP-20 series.

Q: What is the primary reason to transition from 745036-2 to 5745036-2?

A: The 745036-2 is classified as obsolete, while the 5745036-2 maintains active product status. Active status ensures component availability, manufacturing continuity, and access to technical documentation. Additionally, the 5745036-2 is ROHS3 compliant, addressing regulatory requirements in jurisdictions enforcing RoHS directives.

Q: Are there differences in dielectric material between the two parts?

A: The 745036-2 specifies polyamide (PA) nylon with glass filling, while the 5745036-2 is designated as thermoplastic. Both materials provide equivalent electrical insulation performance for signal contact applications within the specified operating parameters.

Q: Does the 5745036-2 include the same grounding indents feature?

A: Yes. Both the 745036-2 and 5745036-2 incorporate grounding indents as a standard feature of the connector housing design.

Q: What is the packaging difference between these parts?

A: The 745036-2 packaging is not specified in available documentation. The 5745036-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are contacts included with either part?

A: No. Both the 745036-2 and 5745036-2 are connector housing plugs supplied without contacts. Male contacts must be sourced separately and assembled into the housing.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts carry MSL 1 (unlimited), indicating no moisture-related handling restrictions during storage, transportation, or assembly operations.

Q: What is the shell finish thickness specification for the 5745036-2?

A: The 5745036-2 specifies a shell finish thickness of 200µin (5.08µm) for the tin plating on the steel shell. The 745036-2 does not provide a documented finish thickness specification.

Q: Are both parts classified under the same export control and tariff codes?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, indicating equivalent export control and tariff treatment.

Q: Can the 5745036-2 be used in applications requiring RoHS compliance?

A: Yes. The 5745036-2 is ROHS3 compliant, satisfying RoHS directive requirements. The 745036-2 is RoHS non-compliant and should not be used in applications with RoHS compliance mandates.
