L77DFE09SAM4VF2 Equivalent & Substitute Parts

Part Overview

The L77DFE09SAM4VF2 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This female sockets connector features right-angle panel mount through-hole termination with solder attachment. The connector is classified as active product status and is designed for signal applications requiring reliable mating interfaces in industrial and commercial equipment.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when inventory optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle connectors is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (9)
• Number of rows (2)
• Shell size and connector layout (1 / DE, E)
• Mounting type (Panel Mount, Through Hole, Right Angle)
• Termination method (Solder)
• Contact type (Signal)
• Material flammability rating (UL94 V-0)

Allowable Variation Parameters:

• Shell material finish (Tin Plated vs. Nickel Plated)
• Contact finish thickness (20.0µin vs. Flash)
• Flange feature design (Mating Side Screwlock vs. Housing/Shell)
• Backset spacing (within 0.001" tolerance: 0.319" vs. 0.318")
• Current rating (7.5A vs. 5A, where lower rating is acceptable in applications not requiring maximum current)
• Operating temperature upper limit (155°C vs. 105°C, where lower limit is acceptable in applications not requiring full range)
• Dielectric material composition (Thermoplastic Glass Filled vs. Polyamide PA9T Nylon 9T)

The substitute part 182-009-213R531 (NorComp Inc.) meets all mandatory matching parameters and operates within allowable variation ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L77DFE09SAM4VF2): Select the original Amphenol ICC part when applications require the full operating temperature range (-55°C to 155°C) or when the higher current rating of 7.5A is necessary. This part maintains active product status with RoHS compliance and is available in current inventory.

Substitute Part Selection (182-009-213R531): The NorComp Inc. part 182-009-213R531 is suitable for applications where operating temperature does not exceed 105°C and current requirements do not exceed 5A. Both parts maintain UL94 V-0 flammability rating and active product status. The substitute part carries ROHS3 compliance and is available in higher inventory quantity (7246 units). The nickel-plated steel shell and polyamide dielectric material provide equivalent performance within the specified parameter ranges.

Compliance Considerations: Both parts are RoHS compliant and carry EAR99 ECCN classification. The substitute part is REACH unaffected. Selection between these parts does not introduce compliance risk when application parameters remain within the substitute part's electrical and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 182-009-213R531 be used as a direct replacement for the Amphenol L77DFE09SAM4VF2?

A: The NorComp part is a functional substitute when application requirements do not exceed 5A current and 105°C operating temperature. Both connectors share identical D-Sub 9-position receptacle configuration, right-angle panel mount through-hole solder termination, and UL94 V-0 flammability rating. Backset spacing differs by 0.001" (within standard tolerance). Verify application current and temperature requirements before substitution.

Q: What are the differences in shell material finish between these parts?

A: The Amphenol part features tin-plated steel shell; the NorComp part features nickel-plated steel shell. Both finishes provide corrosion resistance suitable for signal-level D-Sub applications. Nickel plating offers enhanced durability in certain environmental conditions. Material finish selection does not affect electrical performance for signal applications.

Q: Are there differences in contact finish specifications?

A: The Amphenol part specifies 20.0µin (0.51µm) gold contact finish thickness; the NorComp part specifies flash gold finish. Both provide gold contact surfaces for reliable signal transmission. Flash finish represents minimal gold plating thickness. For signal-level applications, both finishes are functionally equivalent.

Q: What is the significance of the flange feature difference?

A: The Amphenol part features mating-side female screwlock (4-40); the NorComp part features housing/shell mounting (4-40). Both designs provide secure panel mounting with identical screw specification. The flange feature difference reflects design variation between manufacturers but does not affect connector mating or electrical performance.

Q: How do the operating temperature ranges affect substitution?

A: The Amphenol part operates from -55°C to 155°C; the NorComp part operates from -55°C to 105°C. The substitute part is suitable only for applications where maximum operating temperature does not exceed 105°C. Applications requiring operation above 105°C must use the original Amphenol part.

Q: What is the current rating difference and when does it matter?

A: The Amphenol part is rated for 7.5A; the NorComp part is rated for 5A. The substitute part is suitable for applications drawing 5A or less. Applications requiring current between 5A and 7.5A must use the original Amphenol part.

Q: Are both parts available in the same packaging format?

A: The Amphenol part packaging is not specified in available documentation. The NorComp part is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes before finalizing substitution.

Q: Do both parts carry equivalent compliance certifications?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability rating. The Amphenol part is RoHS compliant; the NorComp part is ROHS3 compliant. The NorComp part is REACH unaffected. Both carry EAR99 ECCN classification. Compliance status does not present barriers to substitution.
