Equivalent & Substitute Parts Reference: L717HDD78POL2

Part Overview

The L717HDD78POL2 is an Amphenol ICC 78-position D-Sub High Density plug connector with male pins, designed for through-hole solder termination. This connector is rated for 3A current and 250V operation, with an operating temperature range of -55°C to 155°C. The part carries an active product status and is RoHS compliant. Substitute parts may be required due to inventory availability, design revision changes, or specific mounting configuration requirements in circuit board layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters across all parts:

• Connector Configuration: 78 positions, 4 rows, D-Sub High Density (Shell Size 5)
• Connector Type: Plug with Male Pins
• Termination Method: Solder
• Contact Type: Signal
• Flammability Rating: UL94 V-0 compliance
• Basic Compliance: RoHS or ROHS3 compliance status

The identified substitute parts maintain these core electrical and mechanical characteristics. Variations exist in secondary attributes including shell material finish (tin-plated vs. nickel-plated), contact finish (gold vs. unspecified), mounting configuration (through-hole only vs. panel mount with through-hole options), operating temperature ranges, and current ratings. These variations define specific application suitability but do not preclude functional substitution where the primary connector architecture is preserved.

Parameter Comparison

Engineering Selection Recommendations

Primary Application Match: The L717HDD78POL2 is the baseline reference. All four substitute parts maintain active product status and UL94 V-0 flammability compliance, qualifying them for equivalent electrical function in D-Sub High Density 78-position applications.

For Temperature-Critical Applications: The L717HDD78POL2 supports the widest operating temperature envelope (-55°C to 155°C). The HARTING 09565617712 operates within -40°C to 85°C, and the NorComp parts operate within -50°C to 100°C. Selection of the original L717HDD78POL2 is required for applications requiring the full -55°C lower limit or the 155°C upper limit.

For Current-Limited Applications: The L717HDD78POL2 and all NorComp variants (180-078-113R001, 180-078-113R011, 180-078-113R031) support 3A current rating. The HARTING 09565617712 supports 2A current rating and must not be substituted in circuits exceeding 2A per contact.

For Mounting Configuration: The L717HDD78POL2 supports through-hole mounting only. The NorComp variants offer panel mount configurations in addition to through-hole, providing design flexibility for panel-mounted applications. Mounting type selection depends on board layout requirements.

For Voltage Applications: The L717HDD78POL2 specifies 250V rating. Substitute parts do not specify voltage rating and should be evaluated against specific circuit voltage requirements.

For Compliance Continuity: All substitute parts carry RoHS3 compliance. The L717HDD78POL2 carries RoHS compliance. The NorComp parts include REACH Unaffected status, providing additional regulatory assurance in REACH-restricted markets.

Frequently Asked Questions (FAQ)

Q: Can 09565617712 (HARTING) be used as a direct substitute for L717HDD78POL2?

A: Functional substitution is constrained by current rating. The HARTING part supports 2A maximum, while the original supports 3A. Substitution is valid only when circuit current requirements do not exceed 2A per contact. The narrower operating temperature range (-40°C to 85°C vs. -55°C to 155°C) further restricts substitution to applications within this temperature envelope.

Q: What is the difference between the three NorComp substitutes (180-078-113R001, 180-078-113R011, 180-078-113R031)?

A: All three NorComp variants share identical electrical specifications (78 positions, 4 rows, 3A current, UL94 V-0, brass contacts with gold flash finish, -50°C to 100°C temperature range). The distinction lies in flange configuration: 180-078-113R001 features unthreaded housing shell, 180-078-113R011 features board-side 4-40 threads, and 180-078-113R031 features mating-side 4-40 threads. Panel mount hole placement differs accordingly. Selection depends on mechanical mounting requirements in the target circuit board design.

Q: Are these substitutes electrically equivalent if voltage and current requirements are satisfied?

A: Yes. All parts maintain the core D-Sub High Density 78-position plug architecture with male pins, solder termination, signal contact type, and UL94 V-0 flammability rating. Electrical equivalence is established when operating parameters (current, voltage, temperature) fall within the rated specifications of the substitute part. Mechanical mounting configurations differ and must align with board design.

Q: What compliance status applies when substituting with NorComp parts?

A: The NorComp parts (180-078-113R series) carry ROHS3 compliance and REACH Unaffected status. For applications requiring RoHS certification continuity, these parts satisfy ROHS3 requirements. The original L717HDD78POL2 carries RoHS compliance. When substituting for regulatory compliance purposes, confirm that ROHS3 equivalence satisfies design and market requirements.

Q: Is shell material finish (tin-plated vs. nickel-plated) electrically significant for signal integrity?

A: Both finishes provide corrosion protection and electrical conductivity. The original part features tin plating; substitute parts feature nickel plating. No electrical performance difference exists for signal transmission in D-Sub High Density applications. Selection can be driven by environmental exposure, assembly process compatibility, or supply chain availability.
