Substitute Part Grouping Explanation

The identified substitute parts (10090928-P264VLF and 10090928-P264XLF) are qualified alternatives based on the following critical parameters that determine substitution eligibility:

Matching Parameters:

• 26 Position D-Sub High Density Plug, Male Pins configuration
• 3-row connector layout with DA/A shell size
• Through Hole solder termination
• 250V voltage rating
• -55°C ~ 105°C operating temperature range
• RoHS Compliance and REACH Unaffected status
• Thermoplastic, Glass Filled dielectric material
• EAR99 ECCN classification
• Black color housing

Allowed Variations:

• Flange Feature: Main part uses Housing/Shell (Unthreaded); substitutes use Board Side (4-40) with Mating Side Female Screwlock (4-40)
• Shell Finish: Main part (Tin Plated) differs from substitutes (Nickel Plated); both provide corrosion protection within connector category specifications
• Contact Material: Main part (Brass) differs from substitutes (Copper Alloy); both meet electrical conductivity requirements for signal contacts
• Current Rating: Main part rated at 3A; substitutes rated at 2.5A per Contact
• Contact Finish Thickness: Main part (16.0µin/0.41µm) differs from substitutes (Flash); both provide gold plating within acceptable parameters for this connector type

Parameter Comparison

Engineering Selection Recommendations

L777HDA26POL2 is the primary specification part with Active product status and immediate availability (1145 units in stock). This part features tin-plated steel shell finish and brass contacts with specified gold plating thickness (16.0µin), providing established performance baseline for applications requiring these specific material properties.

10090928-P264VLF and 10090928-P264XLF are active alternatives from the Amphenol ICC (FCI) product line with confirmed RoHS and REACH compliance. Both parts share identical functional D-Sub HD 26-position connector architecture and electrical specifications (250V, -55°C to 105°C). Selection between these substitutes depends on flange configuration requirements: the P264VLF includes board-side locking features with mating-side female screwlock (4-40), while the P264XLF provides board-side mounting without mating-side screwlock.

The 2.5A current rating per contact in both substitute parts (versus 3A in the main part) requires evaluation against circuit load specifications. Nickel plating on substitutes provides equivalent corrosion resistance to tin plating for the D-Sub connector category. Copper alloy contacts in substitutes meet conductivity requirements for signal applications.

10090928-P264XLF carries explicit UL94 V-0 flammability rating, aligning with the main part specification.

Frequently Asked Questions (FAQ)

Q: Are these three connectors electrically interchangeable? A: Yes. All three parts share identical 26-position D-Sub HD configuration, 250V rating, and -55°C to 105°C operating range. The 2.5A per contact rating in substitutes must be verified against circuit current requirements; if total current per contact does not exceed 2.5A, substitutes are electrically equivalent.

Q: What is the primary difference between the three parts? A: The main differences are: flange mounting style (unthreaded housing versus board-side 4-40 mounting with optional mating-side screwlock), shell plating material (tin versus nickel), and contact base material (brass versus copper alloy). Functionally, these variations address different PCB mounting and mechanical retention requirements.

Q: Can I substitute 10090928-P264VLF or 10090928-P264XLF for L777HDA26POL2 if my PCB is already designed for unthreaded housing? A: Direct mechanical substitution requires flange compatibility. The substitute parts feature board-side 4-40 mounting holes; if your PCB is designed only for unthreaded housing interface, mechanical adaptation is necessary. Electrical performance remains equivalent once mechanically secured.

Q: Which substitute part should I use if I need mating-side screwlock capability? A: 10090928-P264VLF includes female screwlock (4-40) on the mating side, providing mechanical retention during mating. 10090928-P264XLF does not include this feature.

Q: Is the flash gold plating on substitute parts adequate? A: Flash gold plating on 10090928-P264VLF and 10090928-P264XLF meets specification for signal contact applications in D-Sub connectors. The specified 16.0µin thickness on L777HDA26POL2 provides additional gold layer; both plating levels are within acceptable ranges for this connector category, provided contact force and electrical requirements are met.

Q: Are there any compliance or regulatory differences between these parts? A: All three parts are RoHS Compliant, REACH Unaffected, and carry EAR99 ECCN classification. 10090928-P264XLF and L777HDA26POL2 both specify UL94 V-0 flammability rating. 10090928-P264VLF does not include specified flammability rating in provided data; flammability requirements must be confirmed with supplier if application-critical.

Q: What inventory availability should I expect? A: L777HDA26POL2 has 1145 units in stock, 10090928-P264VLF has 1738 units, and 10090928-P264XLF has 687 units available from current inventory.
