HARTING 09684635813 D-Sub Plug 37-Position Right Angle Solder Connector

Part Overview

The HARTING 09684635813 is a 37-position D-Sub plug connector with right-angle solder termination, designed for through-hole PCB mounting. This connector features male pins, a 4-position shell size (DC, C layout), and mating-side female screwlock fastening. The part is actively manufactured and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable signal connectivity.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component standardization across multiple suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09684635813 is determined by strict alignment of the following critical parameters:

Connector Configuration: 37-position D-Sub plug with male pins
Shell Size and Layout: 4 (DC, C) geometry
Mounting Orientation: Right-angle through-hole configuration
Termination Method: Solder attachment
Backset Spacing: 0.318" (8.08mm)
Flange Type: Mating-side female screwlock (4-40) fastening

Substitute parts must maintain these core specifications to ensure mechanical fit and electrical performance. Secondary parameters such as contact finish thickness, shell material finish, and dielectric material may vary within acceptable engineering tolerances provided that the primary electrical and mechanical characteristics remain equivalent.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS regulations, ensuring long-term availability and environmental compliance.

Primary Substitutes (Highest Compatibility)

NorComp 182-037-113R181 and Amphenol D37P33E4GV00LF are the closest functional equivalents to the HARTING 09684635813. Both maintain the mating-side female screwlock (4-40) flange configuration, identical shell geometry, and solder termination. The Amphenol part extends the operating temperature range to 125°C, matching the original specification. Both parts are actively manufactured with substantial inventory availability.

Secondary Substitutes (Acceptable with Design Consideration)

NorComp 182-037-113R531 and Amphenol D37P33E4GX00LF feature housing-shell (4-40) flange mounting instead of mating-side screwlock. These parts maintain all other critical parameters and are suitable for applications where flange configuration flexibility exists. The Amphenol part maintains the full -55°C to 125°C operating range.

Limited Substitutes (Application-Dependent)

NorComp 182-037-113R161 features an unthreaded housing/shell flange and operates to 105°C, reducing compatibility for applications requiring mating-side screwlock fastening or extended high-temperature operation.

Mercury 621-037-260-013 operates to only 85°C and carries a reduced current rating of 3A per contact, making it unsuitable for applications requiring the full 6.5A capability or extended temperature performance of the original part.

Frequently Asked Questions (FAQ)

Q: Can I substitute NorComp 182-037-113R181 for HARTING 09684635813 in my design?

A: Yes. Both parts share identical 37-position D-Sub plug configuration, 4 (DC, C) shell size, right-angle through-hole mounting, solder termination, and mating-side female screwlock (4-40) flange. Operating temperature ranges differ slightly (-55°C to 105°C versus -55°C to 125°C), so verify your application's thermal requirements.

Q: What is the difference between the Amphenol D37P33E4GV00LF and D37P33E4GX00LF?

A: Both parts are mechanically and electrically equivalent 37-position D-Sub plugs with identical operating temperature (-55°C to 125°C) and current ratings (5A per contact). The primary difference is flange configuration: D37P33E4GV00LF features mating-side female screwlock (4-40), while D37P33E4GX00LF features housing-shell (4-40) mounting. Select based on your PCB layout and fastening requirements.

Q: Why does Mercury 621-037-260-013 have a lower current rating?

A: Mercury 621-037-260-013 is rated at 3A per contact compared to 6.5A for the HARTING part. This reduced rating reflects the contact design and material specifications of that particular connector series. Use this part only in applications where current requirements do not exceed 3A per contact.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 or RoHS compliance certification, ensuring compatibility with environmental regulations and long-term supply chain stability.

Q: What packaging formats are available?

A: HARTING 09684635813 is supplied in bulk packaging. NorComp parts (182 series) are supplied in trays. Amphenol parts (Delta D series) are supplied in trays. Mercury 621-037-260-013 is supplied in bulk. Verify packaging requirements with your procurement process.

Q: Can I use these parts interchangeably on the same PCB?

A: Mechanical interchangeability depends on flange configuration. Parts with identical flange types (mating-side screwlock or housing-shell) are directly interchangeable. Parts with different flange configurations require PCB layout modifications. Verify backset spacing (all parts maintain 0.318" / 8.08mm) and contact pin assignments before substitution.
