L77HDAG26SOL2

Part Overview

The L77HDAG26SOL2 is a 26-position D-Sub High Density receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole mounted component features female sockets with solder termination and is classified as Active status. Finding substitute parts is necessary due to inventory availability, lead time constraints, or preferred supplier consolidation while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution criteria for D-Sub High Density receptacle connectors are determined by the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Connector configuration: 26-position, 3-row, High Density layout (Shell Size 2, DA/A)
• Receptacle, female socket type with through-hole mounting
• Solder termination method
• Voltage rating of 250V or greater
• Operating temperature range encompassing -55°C to 105°C
• UL94 V-0 flammability compliance
• RoHS compliance status
• Gold contact finish (flash thickness)

The substitute parts 10090929-S264VLF and 10090929-S264XLF meet these critical mechanical and electrical parameters. Both are Amphenol ICC (FCI) products with identical connector configuration, mounting type, and shell size. Variations in contact current rating (2.5A per contact versus 3A) and shell material finish (nickel plated versus tin plated) represent acceptable parameter deviations within the D-Sub High Density category when application requirements allow.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with RoHS compliance and UL94 V-0 flammability certification, ensuring continued supply chain viability and regulatory compliance. The L77HDAG26SOL2 primary part and both substitute parts (10090929-S264VLF and 10090929-S264XLF) are manufactured by Amphenol ICC, confirming established supplier quality and manufacturing standards.

The substitute parts 10090929-S264VLF and 10090929-S264XLF are electrically and mechanically interchangeable within the parameter allowances of D-Sub High Density receptacle applications. The current rating difference (3A versus 2.5A per contact) requires circuit-level verification to confirm adequacy for the intended application. The shell material finish difference (tin plated versus nickel plated) does not affect functional compatibility, though environmental exposure conditions should be considered. The Board Lock feature present on the substitute parts provides additional mechanical retention without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 10090929-S264VLF and 10090929-S264XLF fully compatible with the L77HDAG26SOL2?

A: Both substitute parts meet the critical mechanical and electrical parameters for D-Sub High Density receptacle connectors. The 26-position, 3-row configuration with High Density layout, through-hole mounting, solder termination, 250V voltage rating, and operating temperature range are identical. Verification of the 2.5A per contact current rating against application requirements is necessary.

Q: What is the difference between the two substitute parts?

A: The 10090929-S264VLF includes a female screwlock feature at the mating side (4-40), while the 10090929-S264XLF does not specify this feature. Both parts are otherwise functionally equivalent and share identical electrical and mechanical specifications.

Q: Does the nickel plating on the substitute parts affect performance compared to tin plating?

A: Shell material finish does not affect the electrical performance of the connector within the specified voltage and current parameters. Nickel plating provides equivalent corrosion resistance to tin plating in standard operating environments. Environmental exposure conditions, such as aggressive chemical or salt spray environments, require application-specific evaluation.

Q: Can these connectors be used interchangeably in the same circuit board design?

A: Yes. All three parts share identical through-hole mounting footprints, solder termination compatibility, and connector layout. PCB designs using the L77HDAG26SOL2 may substitute either 10090929-S264VLF or 10090929-S264XLF without modification to the board layout or assembly process, provided that the current rating difference (2.5A per contact) meets application requirements.

Q: What does the Board Lock feature on the substitute parts provide?

A: The Board Lock feature mechanically secures the connector to the printed circuit board, preventing accidental removal during handling and assembly operations. This feature is additive and does not introduce incompatibility with applications not requiring mechanical retention.
