Key Parameters

Substitute Part Grouping Explanation

Substitution of the L17HTNCP4R1C is determined by strict equivalence across the following critical parameters:

Core Functional Parameters (Must Match):

• Connector type: D-Sub Plug with Male Pins
• Number of positions: 37
• Shell size / connector layout: 4 (DC, C)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Backset spacing: 0.318" (8.08mm)
• Material flammability rating: UL94 V-0

Electrical Parameters (Must Be Compatible):

• Current rating: 5A minimum
• Voltage rating: 300V minimum
• Operating temperature range: Must encompass -55°C to 150°C or be compatible with application requirements

Mechanical Parameters (Flange Feature Considerations): Substitute parts are grouped by flange feature type. The main part features Board Side (4-40) mounting. Substitutes with different flange features (Housing/Shell, Mating Side Female Screwlock) are functionally equivalent for signal transmission but differ in mechanical mounting configuration.

Compliance Parameters: All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent Parts (Highest Compatibility):

The D37P33E4GX00LF and D37P33E4GV00LF (Amphenol ICC FCI, Delta D series) are functionally equivalent to the L17HTNCP4R1C. Both maintain identical connector specifications, current ratings, flammability ratings, and RoHS compliance. The primary difference is flange feature configuration: D37P33E4GX00LF features Housing/Shell (4-40) mounting, while D37P33E4GV00LF features Mating Side Female Screwlock (4-40) mounting. Selection between these variants depends on the specific mechanical mounting requirements of the application.

Secondary Equivalent Parts (Temperature Consideration):

The HARTING parts 09684635812 and 09684637813 provide functional equivalence with higher current ratings (6.5A versus 5A). However, the maximum operating temperature is reduced to 125°C compared to the L17HTNCP4R1C specification of 150°C. These parts are suitable for applications where the 125°C upper temperature limit is acceptable and higher current capacity is beneficial.

NorComp Inc. Series 182 Parts (Temperature and Mounting Consideration):

The NorComp 182-037-113R161, 182-037-113R181, and 182-037-113R531 connectors provide mechanical and electrical equivalence with the following considerations:

• Maximum operating temperature is 105°C, which is lower than the L17HTNCP4R1C specification of 150°C. These parts are suitable only for applications with maximum operating temperatures not exceeding 105°C.
• All three NorComp variants support Panel Mount in addition to Through Hole mounting, providing additional mechanical flexibility.
• Contact material is Brass rather than Copper Alloy, with Gold flash finish maintained.
• Flange features vary: 182-037-113R161 (Housing/Shell, Unthreaded), 182-037-113R181 (Mating Side Female Screwlock), 182-037-113R531 (Housing/Shell with 4-40 threading).

Compliance and Product Status:

All substitute parts maintain active product status and UL94 V-0 flammability rating. RoHS compliance is confirmed across all variants. Parts manufactured by HARTING and NorComp Inc. carry ROHS3 certification, while Amphenol ICC parts carry standard RoHS certification. Both compliance levels are acceptable for equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can the D37P33E4GX00LF be used as a direct replacement for the L17HTNCP4R1C?

A: Yes. Both connectors share identical core specifications: 37 positions, D-Sub configuration, right angle through-hole solder termination, 5A current rating, UL94 V-0 flammability rating, and RoHS compliance. The primary difference is the flange feature (Housing/Shell 4-40 versus Board Side 4-40). Substitution is valid if the Housing/Shell mounting configuration is compatible with the application's PCB layout.

Q: What is the difference between the flange features on these D-Sub connectors?

A: Flange features determine the mechanical mounting interface. Board Side (4-40) mounting places the flange on the component side of the PCB. Housing/Shell (4-40) mounting places the flange on the connector shell itself. Mating Side Female Screwlock (4-40) places the flange on the mating connector interface. Selection depends on the specific mechanical mounting requirements and PCB design of the application.

Q: Why do the HARTING parts have a higher current rating (6.5A) than the L17HTNCP4R1C (5A)?

A: Current rating differences reflect design variations in contact geometry and material composition. The HARTING parts 09684635812 and 09684637813 are rated for 6.5A per contact, while the L17HTNCP4R1C is rated for 5A. Applications designed for 5A operation can use the HARTING parts without concern. Applications requiring the full 6.5A capacity should verify that the L17HTNCP4R1C meets the minimum current requirement.

Q: Are the NorComp 182 series connectors suitable replacements for high-temperature applications?

A: The NorComp 182 series connectors have a maximum operating temperature of 105°C, compared to the L17HTNCP4R1C specification of 150°C. These parts are suitable only for applications where the maximum operating temperature does not exceed 105°C. For applications requiring operation above 105°C, the L17HTNCP4R1C, D37P33E4GX00LF, D37P33E4GV00LF, or HARTING parts (rated to 125°C) are appropriate.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both RoHS and ROHS3 represent compliance with the Restriction of Hazardous Substances directive. ROHS3 is the current iteration of the directive. Parts carrying either certification are acceptable for equivalent substitution in applications requiring RoHS compliance.

Q: Can I substitute a connector with a different contact material (Brass versus Copper Alloy)?

A: Yes. Both Brass and Copper Alloy are acceptable contact materials for D-Sub connectors. The functional performance difference is negligible for signal transmission applications. Both materials support the specified current and voltage ratings when finished with gold plating.

Q: What does "Flash" gold finish thickness mean?

A: Flash gold finish refers to a very thin layer of gold plating applied to the contact surface, typically less than 1 micrometer. This finish provides corrosion resistance and maintains electrical conductivity while minimizing material cost. Flash finish is standard for D-Sub connectors and is functionally equivalent across all listed parts.

Q: Are there any packaging differences between these connectors?

A: Yes. The L17HTNCP4R1C and NorComp parts are supplied in Tray packaging, while HARTING parts are supplied in Bulk packaging. Amphenol ICC FCI parts (D37P33 series) are supplied in Tray packaging. Packaging differences do not affect connector functionality but may impact handling, storage, and ordering procedures.

Q: Which substitute part has the highest inventory availability?

A: The NorComp 182-037-113R531 has the highest inventory with 5354 pieces in stock, followed by D37P33E4GX00LF with 1776 pieces. The L17HTNCP4R1C has 738 pieces available. Inventory levels should be verified at the time of procurement, as stock quantities change continuously.
