Substitute Part Grouping Explanation

Substitute parts 10090929-S154VLF and 10090929-S154XLF are identified as electrical and mechanical equivalents based on the following matching criteria:

Matching Electrical Parameters:

• Connector style: D-Sub, High Density
• Connector type: Receptacle, Female Sockets
• Number of positions: 15
• Number of rows: 3
• Shell size and layout: 1 (DE, E) High Density
• Voltage rating: 250V
• Operating temperature range: -55°C ~ 105°C
• Material flammability: UL94 V-0
• Termination method: Solder
• Compliance: RoHS Compliant, REACH Unaffected

Matching Mechanical Parameters:

• Mounting type: Through Hole
• Vertical orientation
• Contact type: Signal
• Color: Black
• Dielectric material: Thermoplastic, Glass Filled
• Contact finish: Gold Flash

Differing Parameters (Allowable Variations):

• Current rating: L77HDEG15SOL2 rated 3A; substitutes rated 2.5A per contact
• Flange design: L77HDEG15SOL2 board-side M3; substitutes board-side 4-40 with optional female screwlock (10090929-S154VLF) or board lock feature (10090929-S154XLF)
• Shell material finish: L77HDEG15SOL2 steel tin-plated; substitutes steel nickel-plated
• Contact material: L77HDEG15SOL2 brass; substitutes copper alloy

These variations are within acceptable substitution parameters for D-Sub High Density connectors in equivalent 15-position configurations.

Parameter Comparison

Engineering Selection Recommendations

All three connectors—L77HDEG15SOL2, 10090929-S154VLF, and 10090929-S154XLF—are active production parts with RoHS compliance and REACH unaffected status. All parts meet UL94 V-0 flammability requirements and operate within the -55°C to 105°C temperature range, supporting equivalent environmental performance.

The L77HDEG15SOL2 features a higher current rating of 3A compared to the 2.5A per contact rating of substitute parts. Applications with current demands at or below 2.5A per contact support use of either substitute. The flange design differs: L77HDEG15SOL2 uses M3 board-side mounting, while substitutes employ 4-40 screw specifications, with 10090929-S154VLF including female screwlock capability and 10090929-S154XLF including board lock feature.

Shell material finish differs: L77HDEG15SOL2 specifies tin plating while substitutes specify nickel plating, both with gold-flash contact finishing. Contact material composition differs: L77HDEG15SOL2 uses brass while substitutes use copper alloy. All parts employ solder termination and identical 15-position high-density receptacle configurations.

Part selection should be based on current rating requirements, flange mounting specifications, and environmental compliance needs for the target application.

Frequently Asked Questions (FAQ)

What makes these parts substitutes for the L77HDEG15SOL2?

The substitute parts maintain electrical and mechanical equivalence through identical connector style (D-Sub High Density), position count (15), row configuration (3), socket type (female receptacle), voltage rating (250V), temperature range (-55°C to 105°C), and termination method (solder). All parts achieve the same UL94 V-0 flammability rating and RoHS compliance status.

Can I use a substitute part if my application requires 3A current rating?

No. The L77HDEG15SOL2 is rated for 3A, while both substitute parts are rated for 2.5A per contact. Applications requiring 3A current must use the L77HDEG15SOL2 or select alternative connectors with appropriate current ratings.

What is the difference between the two substitute parts?

Both 10090929-S154VLF and 10090929-S154XLF share identical electrical specifications and are both FCI-branded parts with 2.5A current ratings. The 10090929-S154VLF includes female screwlock provision on the mating side, while 10090929-S154XLF features a board lock characteristic. Both use 4-40 board-side flange specifications.

Are there compliance differences between the main part and substitutes?

No. All three parts are RoHS Compliant, REACH Unaffected, and carry UL94 V-0 flammability ratings. Moisture sensitivity level is 1 (Unlimited) for all parts, and all carry EAR99 ECCN classification with 8536.69.4040 HTSUS coding.

Why do the substitutes use nickel-plated shells instead of tin-plated?

Shell material finish specifications differ between manufacturing divisions (Commercial Products versus FCI division). Both tin and nickel plating provide corrosion resistance suitable for D-Sub connector applications. Selection should be based on specific environmental or compatibility requirements for your application.

What mounting differences exist between these connectors?

The L77HDEG15SOL2 features M3 board-side flange mounting, while both substitute parts use 4-40 screw-hole specifications. PCB design and mounting hardware compatibility must be verified before substitution.
