The substitute parts listed below meet the mandatory matching parameters and electrical requirements. Variations in shell material finish, contact material composition, and flange features are noted where they differ from the main part specification.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical and Mechanical Compatibility:

The following parts provide complete compatibility with the L17HTNCGPOL2RM54C across all specified electrical and mechanical parameters:

• D37P24A4PL00LF (Amphenol ICC FCI, Delta D Series): Matches current rating (5A per contact), exceeds voltage rating (300V vs. 600V requirement), operates within -55°C ~ 125°C range, maintains UL94 V-0 compliance, and is RoHS Compliant. Solder termination and Housing/Shell (M3) flange feature provide direct mechanical compatibility.

• D37P24B4GV00LF (Amphenol ICC FCI, Delta D Series): Identical electrical specifications to D37P24A4PL00LF with ROHS3 Compliant status. Features mating-side female screwlock (4-40) flange, requiring mechanical accommodation in applications designed for housing/shell mounting.

Elevated Current Rating Alternatives:

• 09654616713 (HARTING): Provides 6.5A current rating, exceeding the 5A requirement. Operating temperature range of -55°C ~ 125°C is within acceptable limits for most applications. UL94 V-0 compliance and ROHS3 Compliant status are maintained. Voltage rating is not specified; applications requiring 600V operation require confirmation.

• 5745074-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 Series): Provides 6A current rating with gold contact finish. Voltage rating of 125V is below the 600V specification; this part is suitable only for applications with lower voltage requirements. Operating temperature range of -55°C ~ 105°C is acceptable for most industrial applications.

Reduced Current Rating Alternative:

• A-DS 37 PP/Z (Assmann WSW Components): Provides 3A current rating, which is below the 5A specification. Voltage rating of 250V is below the 600V requirement. Operating temperature range of -20°C ~ 105°C does not encompass the full -55°C lower limit. This part is suitable only for applications with reduced electrical and thermal requirements.

Press-Fit Termination Alternative:

• 5786534-1 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 Series): Features press-fit termination instead of solder. Current rating and voltage rating are not specified. Operating temperature range of -55°C ~ 105°C is acceptable. This part requires design review to confirm compatibility with press-fit assembly processes and electrical performance requirements.

Compliance Status:

All substitute parts maintain UL94 V-0 material flammability compliance and MSL 1 (Unlimited) moisture sensitivity rating. RoHS compliance is maintained across all candidates, with several offering ROHS3 Compliant status for enhanced regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can D37P24A4PL00LF be used as a direct replacement for L17HTNCGPOL2RM54C?

A: D37P24A4PL00LF is mechanically and electrically compatible. Both parts feature 37-position D-Sub plug configuration with male pins, 2-row layout, shell size 4 (DC, C), through-hole mounting, and solder termination. Current rating matches at 5A per contact. Operating temperature range of -55°C ~ 125°C covers the primary operating window, though the main part extends to 150°C. Voltage rating of 300V is lower than the 600V specification; applications operating below 300V are fully compatible.

Q: What is the difference between housing/shell flange and mating-side screwlock flange?

A: Housing/shell flange (M3 or unthreaded) mounts directly to the printed circuit board or panel. Mating-side female screwlock (4-40) flange provides threaded connection points on the connector face for mechanical locking with mating connectors. Parts with mating-side screwlock require different mechanical accommodation in the application design.

Q: Why does A-DS 37 PP/Z have a lower current rating of 3A?

A: Current rating is determined by contact material composition, contact cross-sectional area, and thermal design. A-DS 37 PP/Z uses brass contacts with flash gold finish, whereas the main part uses copper alloy contacts with 30.0µin gold plating. The 3A rating reflects the electrical performance characteristics of this specific contact design. Applications requiring 5A operation must use parts with 5A or higher current ratings.

Q: Can 5786534-1 with press-fit termination replace the solder-terminated L17HTNCGPOL2RM54C?

A: Press-fit and solder termination are fundamentally different assembly processes. Press-fit termination requires precision-drilled holes and specialized insertion equipment, whereas solder termination uses standard PCB pads and wave or reflow soldering. Mechanical and electrical performance are equivalent when each termination type is properly executed. Substitution requires confirmation that the application assembly process supports press-fit technology.

Q: What is the significance of ROHS3 Compliant versus RoHS Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 Compliant indicates compliance with the most recent regulatory requirements. RoHS Compliant indicates compliance with earlier versions of the standard. Both are acceptable for new designs; ROHS3 Compliant parts provide enhanced regulatory alignment for long-term supply chain stability.

Q: Is the 600V rating of L17HTNCGPOL2RM54C critical for all applications?

A: Voltage rating indicates the maximum voltage the connector can safely withstand without electrical breakdown. Applications operating at voltages below the connector's rated voltage are compatible. For example, a 300V application can use either the 600V-rated main part or the 300V-rated D37P24A4PL00LF. Applications requiring 600V operation must use parts with 600V or higher ratings.

Q: Why do some substitute parts have unspecified voltage or current ratings?

A: Unspecified ratings indicate that the parameter was not provided in the available technical documentation. When ratings are unspecified, the part cannot be confirmed for applications with specific electrical requirements. Contact the manufacturer for complete electrical specifications before selecting parts with unspecified ratings.

Q: What packaging formats are available for these D-Sub connectors?

A: L17HTNCGPOL2RM54C is supplied in Tray packaging. Substitute parts are available in Tray (D37P24A4PL00LF, D37P24B4GV00LF, A-DS 37 PP/Z, 09654616713), Tube (5745074-2), and Bulk (5786534-1) packaging. Packaging format affects handling, storage, and automated assembly compatibility. Confirm packaging requirements with assembly and logistics specifications.

Q: Are all substitute parts available in equivalent stock quantities?

A: Stock availability varies by part number and supplier. Current inventory levels are: L17HTNCGPOL2RM54C (1,017 units), D37P24B4GV00LF (1,157 units), 5745074-2 (1,629 units), 09654616713 (964 units), 5786534-1 (922 units), D37P24A4PL00LF (807 units), and A-DS 37 PP/Z (780 units). Inventory levels are subject to change; confirm availability with suppliers for production requirements.
