• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Flange Feature: Board Side (M3), Housing/Shell (Unthreaded), Mating Side Female Screwlock (4-40), or Board Side (4-40)
• Shell Material Finish: Steel with Tin Plated, Nickel Plated, or Tin-Nickel Plated finishes
• Contact Material: Copper Alloy, Brass, or Phosphor Bronze
• Current Rating: 3A to 6A (within signal application tolerance)
• Voltage Rating: 125V to 600V (application dependent)
• Operating Temperature: -55°C to -20°C minimum; 100°C to 125°C maximum
• Contact Form: Stamped or Machined

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The D37P24A4PL00LF and D37P24B4GV00LF from Amphenol ICC (FCI) Delta D series represent the closest functional equivalents to the L717TSCG37POL2RM5. Both maintain identical operating temperature range (-55°C to 125°C), equivalent current rating (5A per contact), and RoHS compliance. The D37P24A4PL00LF features Housing/Shell (M3) flange configuration matching the main part, while D37P24B4GV00LF includes Mating Side Female Screwlock (4-40) with Board Lock feature. Both utilize Phosphor Bronze contacts with PBT dielectric material and are rated for 300V operation.

Secondary Substitutes (Acceptable with Application Review):

The 5745074-2 from TE Connectivity AMPLIMITE HD-20 series maintains through-hole solder termination and operates across -55°C to 105°C. Current rating is 6A, exceeding the main part specification. Voltage rating is 125V, which is lower than the main part's 600V rating. This substitute is suitable for applications not requiring the full voltage specification of the main part.

The 5786534-1 from TE Connectivity features Press-Fit termination rather than solder, representing a different assembly methodology. Operating temperature range matches the 5745074-2 (-55°C to 105°C). This part is suitable only for applications where press-fit termination is acceptable.

Tertiary Substitutes (Limited Compatibility):

The NorComp 172-E37 series (172-E37-113R001, 172-E37-113R011, 172-E37-113R911) includes Panel Mount capability in addition to through-hole mounting. Operating temperature range is -50°C to 100°C, which does not extend to the -55°C minimum or 125°C maximum of the main part. These parts are suitable for applications operating within the -50°C to 100°C window.

The A-DS 37 PP/Z from Assmann WSW Components operates at -20°C to 105°C, limiting low-temperature performance to -20°C. Current rating is 3A, which is lower than the main part's 5A specification. Voltage rating is 250V. This substitute is appropriate for lower-current signal applications within the specified temperature range.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating. RoHS compliance is present across all options (RoHS Compliant or ROHS3 Compliant). Moisture sensitivity level MSL 1 (Unlimited) is maintained by all parts except the NorComp series, which lists MSL as Not Applicable. REACH status varies: Amphenol ICC parts are REACH Unaffected, TE Connectivity parts are REACH Affected, NorComp parts are REACH Unaffected, and Assmann WSW is REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can the D37P24B4GV00LF replace the L717TSCG37POL2RM5 in all applications?

A: The D37P24B4GV00LF is functionally equivalent for applications requiring the full operating temperature range (-55°C to 125°C) and 5A current rating. The primary difference is the flange configuration: D37P24B4GV00LF features Mating Side Female Screwlock (4-40) with Board Lock, while L717TSCG37POL2RM5 features Board Side (M3). Verify that the mating receptacle and PCB mounting requirements are compatible with the screwlock configuration before substitution.

Q: What is the significance of the flange feature differences?

A: Flange features determine how the connector is mounted and secured. Board Side (M3) uses M3 threaded holes on the PCB for mechanical retention. Board Side (4-40) uses 4-40 threaded holes. Housing/Shell (Unthreaded) provides no threaded mounting. Mating Side Female Screwlock (4-40) includes threaded inserts on the mating connector for cable-side locking. Selection depends on PCB layout, mechanical retention requirements, and whether cable-side locking is necessary.

Q: Are the NorComp 172-E37 series parts suitable for aerospace or military applications?

A: The NorComp 172-E37 series operates at -50°C to 100°C, which does not meet the full temperature specification of the main part (-55°C to 125°C). If the application requires operation at -55°C or above 100°C, these parts are not suitable. Verify application temperature requirements before selection.

Q: What is the difference between solder and press-fit termination?

A: Solder termination requires manual soldering of wire leads to connector contacts during assembly. Press-fit termination (5786534-1) uses mechanical insertion of wire leads into contact cavities without soldering. Press-fit termination offers faster assembly but requires precise wire gauge and insertion force control. Solder termination provides more robust mechanical connection for high-vibration environments. Select based on assembly process capability and application mechanical requirements.

Q: Can the A-DS 37 PP/Z be used in high-current applications?

A: The A-DS 37 PP/Z is rated for 3A current, which is lower than the main part's 5A specification. This part is suitable only for applications requiring 3A or less per contact. For applications requiring 5A or higher current capacity, use the main part or higher-rated substitutes (D37P24A4PL00LF, D37P24B4GV00LF, or 5745074-2).

Q: What does RoHS Compliant versus ROHS3 Compliant mean?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive (2002/95/EC). ROHS3 Compliant indicates compliance with the recast directive (2011/65/EU), which includes additional restricted substances and stricter requirements. Both designations indicate lead-free and hazardous substance-restricted manufacturing. ROHS3 Compliant parts meet current EU regulatory requirements and are preferred for new designs.

Q: Is the 5745074-2 suitable for applications requiring 600V operation?

A: The 5745074-2 is rated for 125V operation, which is significantly lower than the main part's 600V rating. This part is not suitable for applications requiring 600V or higher voltage operation. For high-voltage applications, use the main part L717TSCG37POL2RM5 or equivalent parts rated for 300V or higher (D37P24A4PL00LF or D37P24B4GV00LF).

Q: What packaging options are available for these connectors?

A: Packaging varies by part number. L717TSCG37POL2RM5, NorComp 172-E37 series, A-DS 37 PP/Z, and Amphenol ICC Delta D series are supplied in Tray packaging. TE Connectivity 5745074-2 is supplied in Tube packaging. TE Connectivity 5786534-1 is supplied in Bulk packaging. Verify packaging compatibility with receiving and storage procedures before ordering.

Q: Can substitute parts be mixed in the same assembly?

A: All substitute parts maintain identical 37-position, 2-row D-Sub configuration and are mechanically compatible with standard D-Sub receptacles. However, mixing different contact materials (Copper Alloy, Brass, Phosphor Bronze) or shell finishes (Tin Plated, Nickel Plated, Tin-Nickel Plated) in the same assembly may introduce galvanic corrosion risk in high-humidity environments. Maintain consistency of contact material and shell finish within a single assembly when possible.
