NorComp 680-044-103L031 D-Sub High Density Connector Equivalent & Substitute Parts

Part Overview

The NorComp 680-044-103L031 is a 44-position D-Sub high density plug connector with male pins, designed for panel mount applications. This connector features solder cup termination, steel nickel-plated shell, and gold-flashed contacts rated for 5A operation across -50°C to 100°C. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NorComp 680-044-103L031 is determined by the following critical parameters that must remain consistent:

• 44-position connector with 3-row configuration
• D-Sub high density shell size (3/DB, B layout)
• Male pin connector type
• Steel nickel-plated shell construction
• UL94 V-0 flammability rating
• ROHS3 compliance
• Polybutylene Terephthalate (PBT) dielectric material
• Brass or copper alloy contact material

The three substitute parts identified differ in specific implementation details while maintaining core electrical and mechanical compatibility:

NorComp 180-044-103L011: Active product from NorComp series 180, maintains panel mount configuration with cable-side flange feature and adds shielding capability.

HARTING 09563617713: Through-hole vertical solder mount variant with board lock feature and female screwlock mating interface, operates at reduced current rating (2A) and narrower temperature range (-40°C to 85°C).

HARTING 09563625812: Through-hole right-angle solder mount variant with board lock feature and housing/shell flange, operates at reduced current rating (2A) and narrower temperature range (-40°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

NorComp 180-044-103L011 is the primary substitute for direct replacement in panel mount applications. This part maintains identical electrical ratings (5A, -50°C to 100°C), identical termination method (solder cup), and identical mounting configuration. The 180 series is active product status, ensuring long-term availability. The addition of shielding capability provides enhanced EMI performance without compromising compatibility.

HARTING 09563617713 and HARTING 09563625812 are suitable substitutes only when application requirements permit reduced current capacity (2A maximum) and narrower operating temperature range (-40°C to 85°C). These parts are appropriate for through-hole PCB mount applications where the original panel mount configuration is not required. Both HARTING variants include board lock features for improved mechanical retention on PCBs.

All three substitute parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 180-044-103L031 be used as a direct replacement for the 680-044-103L031?

A: The NorComp 180-044-103L011 is the closest equivalent. Both are 44-position D-Sub high density plugs with panel mount configuration, solder cup termination, and 5A current rating across -50°C to 100°C. The primary difference is the flange feature location (cable side vs. mating side), which does not affect electrical or mechanical compatibility in most applications.

Q: What are the limitations of the HARTING substitutes?

A: HARTING parts 09563617713 and 09563625812 operate at 2A maximum current (versus 5A for the original) and support a narrower temperature range (-40°C to 85°C versus -50°C to 100°C). These parts are through-hole mount variants, not panel mount. Applications requiring the full 5A rating or extended temperature operation must use the NorComp 180-044-103L011.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The NorComp 180-044-103L011, HARTING 09563617713, and HARTING 09563625812 are all ROHS3 compliant, matching the regulatory status of the original 680-044-103L031.

Q: What is the difference between solder cup and solder termination?

A: Solder cup termination (680-044-103L031 and 180-044-103L011) uses cup-shaped contact ends for wire insertion and solder attachment. Solder termination (HARTING variants) uses flat or formed contacts designed for direct PCB pad soldering. The termination method affects assembly process and is not interchangeable without circuit board redesign.

Q: Can the HARTING right-angle variant (09563625812) be used in place of the straight connector?

A: The right-angle configuration changes the connector orientation relative to the PCB. This is a mechanical form factor change that requires circuit board layout modification. Electrical compatibility exists, but physical installation differs significantly.

Q: What inventory status should be considered for long-term supply?

A: The original 680-044-103L031 is obsolete product status. The NorComp 180-044-103L011 is active product with 825 units in stock. HARTING 09563617713 has 974 units in stock, and HARTING 09563625812 has 795 units in stock. For new designs and long-term support, active product status parts are recommended.
