Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 745354-4 is based on electrical and mechanical parameter equivalence within the D-Sub connector category. The substitute part must maintain identical specifications across the following critical parameters:

Electrical Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (37)
• Number of rows (2)
• Shell size and layout (4, DC, C)
• Current rating (6A)
• Voltage rating (125V)
• Contact material (Brass)
• Contact finish (Gold)

Mechanical Parameters:

• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Backset spacing (0.545" / 13.84mm)
• Flange feature (Mating Side, Standard Screws 4-40)
• Shell material and finish (Steel, Tin Plated)
• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)

The substitute part 5745354-4 meets all these criteria and is classified as active product status, providing a direct functional replacement for the obsolete 745354-4.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745354-4 is the direct equivalent substitute for the obsolete 745354-4. Both components are manufactured by TE Connectivity within the AMPLIMITE HDP-20 series and maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, pin count, shell size, termination method, current and voltage ratings, and operating temperature range.

The primary distinction between the main part and substitute is product status and regulatory compliance. The 745354-4 is classified as obsolete, while the 5745354-4 is active product. Additionally, the 5745354-4 achieves ROHS3 compliance, whereas the 745354-4 is RoHS non-compliant. The dielectric material differs between the two parts (Thermoplastic versus Polyamide with glass filling), though both maintain the same UL94 V-0 flammability rating and functional performance characteristics.

For new designs and ongoing production applications, the 5745354-4 is the appropriate selection due to its active status and improved regulatory compliance posture. Existing designs utilizing the 745354-4 can transition to the 5745354-4 without modification to PCB layouts, mating connectors, or electrical circuit parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5745354-4 directly replace the 745354-4 in existing designs?

A: Yes. The 5745354-4 maintains identical electrical and mechanical specifications to the 745354-4 across all critical parameters including pin count, shell size, mounting configuration, current and voltage ratings, and operating temperature range. No design modifications are required for substitution.

Q: What is the difference between the dielectric materials used in these connectors?

A: The 745354-4 uses Thermoplastic dielectric material, while the 5745354-4 uses Polyamide (PA) Nylon with glass filling. Both materials meet the UL94 V-0 flammability rating and maintain equivalent functional performance in the specified operating temperature range of -55°C to 105°C.

Q: Why is the 745354-4 classified as obsolete?

A: The 745354-4 is obsolete product status. The 5745354-4 is the active equivalent component from TE Connectivity and should be used for all new procurement and design applications.

Q: Does the 5745354-4 meet RoHS requirements?

A: Yes. The 5745354-4 is ROHS3 compliant. The original 745354-4 is RoHS non-compliant. If RoHS compliance is a requirement for your application, the 5745354-4 is the appropriate selection.

Q: Are there any packaging differences between these parts?

A: The 745354-4 packaging is listed as unspecified in the provided data. The 5745354-4 is supplied in Bulk packaging. Both parts are available in new original condition with substantial inventory levels.

Q: What is the backset spacing, and why is it important?

A: The backset spacing is 0.545 inches (13.84mm) for both connectors. This measurement defines the distance from the mating face to the rear of the connector body and is critical for PCB layout and mechanical clearance calculations. Both parts maintain identical spacing.

Q: Can these connectors be used interchangeably with other D-Sub 37-position connectors?

A: Interchangeability is determined by matching all electrical and mechanical parameters. The 745354-4 and 5745354-4 are interchangeable with each other. Compatibility with other D-Sub 37-position connectors requires verification of shell size (4, DC, C), mounting type (Through Hole, Right Angle), termination method (Solder), and all electrical ratings.

Q: What is the current and voltage rating for these connectors?

A: Both connectors are rated for 6 Amperes continuous current and 125 Volts maximum voltage. These ratings apply to the overall connector assembly and must be considered in circuit design calculations.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate across the temperature range of -55°C to 105°C. Applications requiring operation outside this range require alternative connector selection.
