Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 745968-4 is determined by the following critical parameters: connector style (D-Sub), connector type (Plug, Male Pins), number of positions (25), number of rows (2), shell size and layout (3 DB, B), mounting type (through hole), and termination method (solder). All identified substitute parts maintain these core specifications.

Substitute parts are grouped into two categories:

Direct Manufacturer Substitutes (TE Connectivity): Parts 5745968-4 and 745968-2 are manufactured by TE Connectivity within the AMPLIMITE HD-20 series. These parts differ only in packaging format (tube versus bulk) and compliance status, while maintaining identical electrical and mechanical specifications.

Cross-Manufacturer Substitutes (Amphenol ICC): Parts L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 are manufactured by Amphenol ICC within the TS series. These parts maintain the core D-Sub 25-position plug configuration with through-hole solder termination but introduce variations in flange feature design (mating side female screwlock), current rating (5A versus 6A), voltage rating (600V versus 125V), contact material (copper alloy versus brass), and dielectric material (thermoplastic glass-filled versus polyester).

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5745968-4: This part is a direct substitute for the 745968-4, differing only in packaging format (tube instead of bulk). The 5745968-4 maintains identical electrical and mechanical specifications, including 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. The 5745968-4 is RoHS Compliant, whereas the main part is RoHS non-compliant. Selection of this part is appropriate when RoHS compliance is required or when tube packaging is preferred for inventory management.

TE Connectivity 745968-2: This part is a direct substitute for the 745968-4 within the same AMPLIMITE HD-20 series, maintaining identical electrical and mechanical specifications. The 745968-2 is packaged in bulk format, matching the main part's packaging. RoHS status is listed as not applicable. This part is suitable for applications where series consistency and bulk packaging are required.

Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309: These parts are cross-manufacturer substitutes from Amphenol ICC's TS series. Both parts maintain the 25-position D-Sub plug configuration with through-hole solder termination and steel tin-plated shells with gold-plated contacts. However, these parts feature a mating side female screwlock (4-40) flange design, reduced current rating (5A versus 6A), elevated voltage rating (600V versus 125V), copper alloy contact material (versus brass), and thermoplastic glass-filled dielectric material (versus polyester). Both Amphenol ICC parts are RoHS Compliant and support an extended operating temperature range of -55°C to 125°C. The L717TSBH25POL2RM8C309 specifies a defined contact finish thickness of 30.0µin (0.76µm), whereas the L717TSBH25POL2RM8 specifies flash thickness. Selection of Amphenol ICC parts is appropriate when higher voltage rating, extended temperature range, RoHS compliance, or screwlock mating features are required, provided that the reduced 5A current rating is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 5745968-4 be used as a direct replacement for the 745968-4?

A: Yes. The 5745968-4 is a direct electrical and mechanical substitute for the 745968-4. Both parts are manufactured by TE Connectivity within the AMPLIMITE HD-20 series and maintain identical specifications for connector type, position count, shell size, mounting type, termination method, current rating (6A), voltage rating (125V), and operating temperature range (-55°C to 105°C). The only differences are packaging format (tube versus bulk) and RoHS compliance status (compliant versus non-compliant).

Q: What are the key differences between TE Connectivity and Amphenol ICC D-Sub 25-position plugs?

A: TE Connectivity 745968-4, 5745968-4, and 745968-2 are AMPLIMITE HD-20 series connectors with unthreaded housing shells, 6A current rating, 125V voltage rating, brass contacts, and polyester dielectric material. Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 are TS series connectors with mating side female screwlock (4-40) flanges, 5A current rating, 600V voltage rating, copper alloy contacts, and thermoplastic glass-filled dielectric material. The Amphenol ICC parts support an extended operating temperature range of -55°C to 125°C compared to -55°C to 105°C for TE Connectivity parts.

Q: Are the Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 parts interchangeable with each other?

A: Yes. Both Amphenol ICC parts are functionally equivalent within the TS series. The primary difference is contact finish thickness specification: L717TSBH25POL2RM8 specifies flash thickness, while L717TSBH25POL2RM8C309 specifies 30.0µin (0.76µm) thickness. Both parts maintain identical electrical and mechanical specifications, including 5A current rating, 600V voltage rating, mating side female screwlock flanges, and -55°C to 125°C operating temperature range.

Q: What packaging formats are available for these D-Sub 25-position plugs?

A: The 745968-4 is supplied in bulk packaging. The 5745968-4 is supplied in tube packaging. The Amphenol ICC parts L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 are supplied in tray packaging. Packaging selection depends on inventory management requirements and order quantity considerations.

Q: Which substitute parts are RoHS Compliant?

A: The 5745968-4, L717TSBH25POL2RM8, and L717TSBH25POL2RM8C309 are RoHS Compliant. The main part 745968-4 is RoHS non-compliant. The 745968-2 has RoHS status listed as not applicable. Selection of RoHS Compliant parts is necessary for applications subject to RoHS regulations.

Q: Can I use an Amphenol ICC part if my application requires 6A current capacity?

A: No. The Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 parts are rated for 5A maximum current, which is lower than the 6A rating of the TE Connectivity parts. If your application requires 6A current capacity, use TE Connectivity 745968-4, 5745968-4, or 745968-2.

Q: What is the difference in voltage rating between the TE Connectivity and Amphenol ICC parts?

A: TE Connectivity 745968-4, 5745968-4, and 745968-2 are rated for 125V maximum voltage. Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 are rated for 600V maximum voltage. The Amphenol ICC parts support higher voltage applications, but the TE Connectivity parts are suitable for standard 125V applications.

Q: Do the Amphenol ICC parts include any additional mechanical features?

A: Yes. The Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 parts feature mating side female screwlock (4-40) flanges and board lock features, in addition to grounding indents. The TE Connectivity parts feature unthreaded housing shells with grounding indents only. The screwlock and board lock features provide enhanced mechanical retention for the Amphenol ICC parts.

Q: What is the operating temperature range for each part?

A: TE Connectivity 745968-4, 5745968-4, and 745968-2 operate from -55°C to 105°C. Amphenol ICC L717TSBH25POL2RM8 and L717TSBH25POL2RM8C309 operate from -55°C to 125°C. The Amphenol ICC parts support a 20°C higher maximum operating temperature.
