L17HTNCGSOL2RM51C Equivalent & Substitute Parts

Part Overview

The L17HTNCGSOL2RM51C is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features female sockets in a vertical orientation with a 2-row configuration (Shell Size 4, DC layout). The connector is actively produced and widely used in applications requiring robust signal transmission across multiple channels.

Substitute parts are identified when equivalent D-Sub receptacle connectors share the same core electrical and mechanical specifications, enabling direct replacement in circuit designs without functional degradation. Substitution eligibility is determined by matching critical parameters including connector type, position count, mounting method, termination style, and electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L17HTNCGSOL2RM51C are qualified based on the following mandatory matching criteria:

Core Electrical and Mechanical Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 37
• Number of Rows: 2
• Shell Size, Connector Layout: 4 (DC, C)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Type: Signal

Electrical Performance Parameters:

• Current Rating: 5A or greater
• Voltage Rating: 300V or greater
• Operating Temperature Range: Must encompass or overlap with -55°C ~ 150°C

Material and Compliance Parameters:

• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: RoHS Compliant or ROHS3 Compliant

Substitute parts identified in this reference meet all mandatory criteria. Variations in shell finish material (nickel-plated versus tin-plated), contact material composition (copper alloy versus phosphor bronze), and dielectric material formulation are permitted within the scope of substitution, as these do not compromise functional compatibility in standard D-Sub receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed in this reference maintain active product status and meet the mandatory substitution criteria for the L17HTNCGSOL2RM51C. Selection among qualified substitutes is based on application-specific requirements and compliance considerations:

Primary Substitutes (Highest Compatibility):

The parts D37S24A4GV00LF, D37S24A4GX00LF, and D37S24A4PL00LF (Amphenol ICC FCI, Delta D series) provide the closest electrical and thermal performance match. These connectors maintain the full operating temperature range (-55°C ~ 125°C), support 5A per contact current rating, and achieve 300V voltage rating. All three are ROHS3 Compliant or RoHS Compliant. The primary distinction among these three variants is the flange feature configuration: D37S24A4GV00LF features mating-side female screwlock, D37S24A4GX00LF features housing/shell mounting, and D37S24A4PL00LF features housing/shell M3 mounting. Selection depends on mechanical mounting requirements in the target application.

Secondary Substitutes (Conditional Compatibility):

The DC37S364TLF (Amphenol ICC FCI, D series) qualifies as a substitute with equivalent electrical performance (5A per contact, 300V rating, -55°C ~ 125°C operating range) and RoHS Compliance. This connector features an unthreaded housing/shell flange and is suitable for applications where threaded mounting is not required.

The A-DF 37 PP/Z (Assmann WSW Components) qualifies as a substitute but operates at reduced current capacity (3A versus 5A) and lower voltage rating (250V versus 600V). This connector is appropriate for applications with lower electrical demands and operates within a narrower temperature range (-20°C ~ 105°C). ROHS3 Compliance is confirmed.

Limited Substitution (Voltage and Temperature Constraints):

The 09644127235 (HARTING) connector meets core mechanical and connector-type specifications but operates at significantly reduced voltage rating (100V versus 600V) and narrower temperature range (-20°C ~ 125°C). This connector is suitable only for applications with low-voltage signal requirements and moderate temperature environments. Current capacity is rated at 7.5A, exceeding the main part specification.

Frequently Asked Questions (FAQ)

Q: Can D37S24A4GV00LF, D37S24A4GX00LF, and D37S24A4PL00LF be used interchangeably with L17HTNCGSOL2RM51C?

A: These three connectors are electrically and mechanically compatible substitutes. The primary difference is the flange feature configuration. D37S24A4GV00LF includes mating-side female screwlock, D37S24A4GX00LF includes housing/shell 4-40 mounting, and D37S24A4PL00LF includes housing/shell M3 mounting. Selection depends on the mechanical mounting interface required by the application. All three maintain equivalent electrical performance and operating temperature range.

Q: What is the significance of the voltage rating difference between L17HTNCGSOL2RM51C (600V) and substitute parts (300V)?

A: The L17HTNCGSOL2RM51C is rated for 600V operation, while most substitute parts are rated for 300V. Substitution is valid only in applications where the actual operating voltage does not exceed 300V. For applications requiring 600V operation, the L17HTNCGSOL2RM51C or DC37S364TLF (300V) must be evaluated against specific circuit requirements. The A-DF 37 PP/Z is rated for 250V and is suitable only for applications with lower voltage demands.

Q: Are there temperature range limitations when substituting with HARTING 09644127235 or Assmann A-DF 37 PP/Z?

A: Yes. The L17HTNCGSOL2RM51C operates from -55°C to 150°C. The HARTING 09644127235 operates from -20°C to 125°C, and the Assmann A-DF 37 PP/Z operates from -20°C to 105°C. Substitution with these parts is valid only in applications where the operating environment remains within their respective temperature ranges. For applications requiring the full -55°C to 150°C range, use D37S24A4GV00LF, D37S24A4GX00LF, D37S24A4PL00LF, or DC37S364TLF.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant refers to the original RoHS Directive (2002/95/EC), while ROHS3 Compliant refers to the recast directive (2011/65/EU). All substitute parts listed meet current environmental compliance requirements. Selection between RoHS Compliant and ROHS3 Compliant parts depends on customer or regional regulatory requirements.

Q: Can the A-DF 37 PP/Z be used in applications designed for 5A current per contact?

A: No. The A-DF 37 PP/Z is rated for 3A maximum current, while the L17HTNCGSOL2RM51C is rated for 5A. Substitution with A-DF 37 PP/Z is valid only in applications where the actual current per contact does not exceed 3A. For applications requiring 5A per contact capacity, use D37S24A4GV00LF, D37S24A4GX00LF, D37S24A4PL00LF, DC37S364TLF, or HARTING 09644127235 (7.5A).

Q: What packaging formats are available for these substitute parts?

A: The L17HTNCGSOL2RM51C is supplied in Tray packaging. Substitute parts are available in the following packaging formats: HARTING 09644127235 (Bulk), Assmann A-DF 37 PP/Z (Tray), Amphenol FCI D37S24A4GV00LF (Tray), Amphenol FCI D37S24A4GX00LF (Tray), Amphenol FCI D37S24A4PL00LF (Tray), and Amphenol FCI DC37S364TLF (Tray). Packaging format does not affect electrical or mechanical compatibility.

Q: Are all substitute parts actively produced?

A: Yes. All substitute parts listed in this reference maintain active product status with current manufacturers. Inventory availability varies by supplier and part number.
