Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

D37P24B4GV00LF (Amphenol ICC, FCI) and D37P24A4PL00LF (Amphenol ICC, FCI) are the most direct substitutes. Both connectors maintain identical connector type, position count, row configuration, shell size, mounting method, and flange feature specifications. Both are rated at 5A per contact with 300V minimum voltage rating, operating temperature range of -55°C to 125°C, and UL94 V-0 flammability rating. D37P24B4GV00LF carries ROHS3 compliance status with REACH affected designation. D37P24A4PL00LF maintains RoHS compliance with REACH unaffected status. Both utilize solder termination with gold-plated contacts and phosphor bronze contact material.

Secondary Substitutes (Acceptable with Parameter Variance):

09654616713 (HARTING) is functionally compatible with higher current rating (6.5A) and identical shell configuration. Operating temperature maximum is reduced to 125°C. ROHS3 compliance is achieved. Contact finish specification is not provided.

5745074-2 (TE Connectivity AMP Connectors) maintains core mechanical compatibility with 6A current rating and gold contact finish. Voltage rating is specified at 125V, which is below the main part specification. Operating temperature maximum is 105°C. RoHS compliance is confirmed with REACH affected status.

Limited Substitution (Parameter Restrictions):

5786534-1 (TE Connectivity AMP Connectors) differs in termination method (Press-Fit instead of Solder) and flange feature (Housing/Shell instead of Mating Side Female Screwlock). Current rating is not specified. This part is suitable only when press-fit termination is acceptable in the application design.

A-DS 37 PP/Z (Assmann WSW Components) has reduced current rating (3A) and voltage rating (250V), both below main part specifications. Operating temperature range is limited to -20°C to 105°C. This part is not recommended for applications requiring the full electrical and thermal performance of the main part.

Compliance Considerations:

The main part L17HTNCHPOL2RM84C is RoHS non-compliant. If RoHS compliance is required for the application, D37P24B4GV00LF, 09654616713, 5745074-2, 5786534-1, and A-DS 37 PP/Z all provide ROHS3 or RoHS compliant alternatives. REACH status varies across substitutes; applications subject to REACH regulations should verify specific substitute compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can D37P24B4GV00LF replace L17HTNCHPOL2RM84C in all applications?

A: D37P24B4GV00LF is mechanically and electrically compatible for applications operating within -55°C to 125°C temperature range and 300V maximum voltage. The main part specification extends to 150°C and 600V. Applications requiring operation above 125°C or above 300V voltage must use the original part or verify substitute suitability through design analysis.

Q: What is the difference between solder and press-fit termination in these D-Sub connectors?

A: Solder termination requires thermal attachment to printed circuit board pads through solder reflow or wave soldering processes. Press-fit termination uses mechanical insertion into plated through-holes without solder. The main part and most substitutes use solder termination. Part 5786534-1 uses press-fit termination and requires different PCB design and assembly procedures.

Q: Why does A-DS 37 PP/Z have a lower current rating than the main part?

A: A-DS 37 PP/Z is rated at 3A per contact, compared to 5A for the main part. This reflects differences in contact material (brass versus copper alloy), contact geometry, and thermal design. Applications requiring 5A per contact must use parts rated for that current level.

Q: Are all substitute parts available in the same packaging as the main part?

A: No. The main part L17HTNCHPOL2RM84C is packaged in Tray. Substitute parts vary: D37P24B4GV00LF and D37P24A4PL00LF are in Tray; 5745074-2 is in Tube; 5786534-1 is in Bulk; 09654616713 is in Tray; A-DS 37 PP/Z is in Tray. Packaging affects handling, storage, and logistics but does not impact electrical or mechanical performance.

Q: What does RoHS non-compliant status mean for the main part?

A: RoHS non-compliant indicates the main part L17HTNCHPOL2RM84C may contain restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, or PBDEs) above specified thresholds. Applications subject to RoHS regulations (primarily European Union markets) must use ROHS3 or RoHS compliant alternatives such as D37P24B4GV00LF, 09654616713, 5745074-2, 5786534-1, or A-DS 37 PP/Z.

Q: Can I use 5745074-2 if my application requires 600V operation?

A: No. Part 5745074-2 is rated at 125V maximum voltage, which is insufficient for 600V applications. The main part L17HTNCHPOL2RM84C and D37P24 series parts (D37P24A4PL00LF and D37P24B4GV00LF) rated at 300V are also below 600V specification. Applications requiring 600V operation must use the original part L17HTNCHPOL2RM84C or verify alternative parts through manufacturer specifications.

Q: What is the significance of contact material differences (copper alloy, brass, phosphor bronze)?

A: Contact material affects electrical conductivity, corrosion resistance, and mechanical durability. Copper alloy and phosphor bronze provide superior electrical and mechanical properties compared to brass. The main part uses copper alloy; D37P24 series uses phosphor bronze; A-DS 37 PP/Z uses brass. For high-reliability applications, copper alloy or phosphor bronze contacts are preferred.

Q: Are the flange features interchangeable between parts?

A: No. The main part features Mating Side Female Screwlock (4-40), which provides threaded mating security. D37P24A4PL00LF features Housing/Shell (M3) threading. A-DS 37 PP/Z features Housing/Shell (Unthreaded). These differences affect mechanical mating and board-level mounting. Substitution requires verification that the flange feature is compatible with the mating connector and mechanical design.
