These parts differ in flange feature configurations and optional board lock features, allowing selection based on specific mounting and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5745589-2

The 5745589-2 is the direct manufacturer equivalent from TE Connectivity AMP Connectors. This part maintains identical electrical and mechanical specifications to the obsolete 745589-2 while offering active product status and ROHS3 compliance. Selection of this part eliminates cross-manufacturer compatibility concerns and maintains supply chain consistency within the TE Connectivity product ecosystem.

Secondary Recommendations: Amphenol ICC L17TF Series

The Amphenol ICC L17TF series connectors provide functional equivalence across all core electrical and mechanical parameters. These parts offer the following advantages:

• Active product status with established supply availability
• RoHS compliance certification
• UL94 V-0 material flammability rating
• Extended operating temperature range (-55°C ~ 125°C)
• Specified current rating (3A) and voltage rating (300V)

Selection within the L17TF series depends on flange feature requirements:

• L17TF3700100: Housing/Shell (Unthreaded) – Direct mechanical equivalent to 745589-2
• L17TF3700101: Housing/Shell (4-40) – For applications requiring 4-40 threaded mounting
• L17TF3700102: Mating Side, Female Screwlock (4-40) – For applications requiring mating-side screwlock with 4-40 threads
• L17TF3700104: Housing/Shell (M3) – For applications requiring M3 threaded mounting
• L17TF3700105: Mating Side, Female Screwlock (M3) – For applications requiring mating-side screwlock with M3 threads
• L17TF3700111: Housing/Shell (4-40) with Board Lock – For applications requiring 4-40 threaded mounting with board lock feature
• L17TF3700114: Housing/Shell (M3) with Board Lock – For applications requiring M3 threaded mounting with board lock feature
• L17TF3700115: Mating Side, Female Screwlock (M3) with Board Lock – For applications requiring mating-side screwlock with M3 threads and board lock feature

Frequently Asked Questions (FAQ)

Q: Can the obsolete 745589-2 be directly replaced with the 5745589-2?

A: Yes. The 5745589-2 is a direct manufacturer substitute from TE Connectivity AMP Connectors with identical electrical and mechanical specifications. The primary differences are active product status and ROHS3 compliance certification.

Q: What are the key differences between TE Connectivity and Amphenol ICC alternatives?

A: Both manufacturers provide 37-position D-Sub receptacles with identical core specifications. TE Connectivity 5745589-2 maintains the original unthreaded housing/shell flange feature. Amphenol ICC L17TF series offers multiple flange feature options (unthreaded, 4-40 threaded, M3 threaded, and screwlock variants) to accommodate different mounting requirements. All Amphenol ICC parts include specified current and voltage ratings and extended temperature range.

Q: Are there packaging differences between these parts?

A: The original 745589-2 packaging is not specified. The 5745589-2 is supplied in Tray packaging. All Amphenol ICC L17TF series parts are supplied in Tray packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the significance of the flange feature variations in the L17TF series?

A: Flange features determine the mechanical mounting interface. Housing/Shell (Unthreaded) provides basic mounting without threaded fasteners. Housing/Shell (4-40) and Housing/Shell (M3) variants include threaded mounting holes for secure fastening. Mating Side, Female Screwlock variants include screwlock mechanisms on the mating connector interface. Board Lock variants provide additional mechanical retention on the PCB. Selection depends on the specific mechanical mounting requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: The original 745589-2 is RoHS non-compliant. The 5745589-2 is ROHS3 compliant. All Amphenol ICC L17TF series parts are RoHS compliant. For applications requiring RoHS compliance, any of the substitute parts are suitable.

Q: What is the operating temperature difference between the main part and substitutes?

A: The 745589-2 operates from -55°C to 105°C. The 5745589-2 maintains this range. All Amphenol ICC L17TF series parts operate from -55°C to 125°C, providing a 20°C extended upper temperature limit. For applications operating above 105°C, the L17TF series is required.

Q: Are the electrical specifications identical across all substitute options?

A: Core electrical specifications (37 positions, 2 rows, signal contact type, gold contact finish) are identical. The Amphenol ICC L17TF series provides additional specified electrical ratings: 3A current rating and 300V voltage rating. The original 745589-2 and 5745589-2 do not specify these ratings. For applications requiring documented electrical ratings, the L17TF series is recommended.

Q: Can L17TF parts be used interchangeably within the series?

A: L17TF parts are interchangeable from an electrical standpoint. Mechanical interchangeability depends on flange feature compatibility with the application's mounting interface. Parts with different flange features (unthreaded, 4-40, M3, screwlock, board lock) are not mechanically interchangeable and must be selected based on specific mounting requirements.
