L77DEH09SAM4

Part Overview

The L77DEH09SAM4 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets, right-angle mounting, and solder termination. The product is actively manufactured and widely used in applications requiring reliable D-Sub signal connectivity. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design alternatives when the primary component becomes unavailable or when specific operational parameters align with alternative designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for D-Sub receptacle connectors is determined by alignment of critical electrical and mechanical parameters: connector type (receptacle with female sockets), position count (9), shell size (1/DE/E), mounting configuration (through-hole, right-angle), and termination method (solder). The substitute parts identified maintain these core requirements within the allowable parameter ranges.

Substitute Part 182-009-213R531 (NorComp Inc.) shares the same connector type, position count, shell size, and solder termination. Parameter differences include panel mount capability (in addition to through-hole), lower current rating (5A versus 7.5A), nickel plating on shell finish versus tin, and reduced operating temperature ceiling (-55°C to 105°C versus 125°C).

Substitute Part DEM09S732N (Amphenol ICC / FCI) maintains identical connector type, position count, shell size, mounting type (through-hole right-angle), and termination. This part supports the same 7.5A current rating and 300V voltage rating as the primary part. Key differences include yellow cadmium plating on the shell, extended operating temperature range (-55°C to 155°C), and phosphor bronze contact material versus brass.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (L77DEH09SAM4): Select when tin-plated shell finish, brass contact material, and glass-filled thermoplastic dielectric are specified requirements. This part supports the full operating temperature range (-55°C to 125°C) and is RoHS Compliant with active product status.

Substitute Part 182-009-213R531 (NorComp): Select when panel mount capability is required in addition to through-hole mounting. This part is ROHS3 Compliant and suitable for applications with current requirements up to 5A. Operating temperature range is limited to -55°C to 105°C. NorComp maintains active product status.

Substitute Part DEM09S732N (Amphenol/FCI): Select when extended operating temperature range (-55°C to 155°C) is required or when phosphor bronze contact material is specified. This part maintains 7.5A current rating and 300V voltage rating matching the primary part. RoHS Compliant with active product status.

Frequently Asked Questions (FAQ)

Q: Can 182-009-213R531 be used directly in place of L77DEH09SAM4 in all applications? A: Not unconditionally. The NorComp part has a lower current rating (5A versus 7.5A) and reduced operating temperature maximum (105°C versus 125°C). Applications requiring currents above 5A or sustained operation above 105°C must use the primary part or DEM09S732N.

Q: What is the difference between nickel plating and tin plating on D-Sub connectors? A: Plating material affects corrosion resistance, electrical conductivity, and material compatibility. Tin plating (L77DEH09SAM4) and nickel plating (182-009-213R531) provide different environmental durability profiles. Selection depends on application environment and mating cycles.

Q: Is DEM09S732N suitable for high-temperature applications? A: DEM09S732N is rated to -55°C to 155°C, providing a 30°C higher operating ceiling than the primary part. Applications operating above 125°C can use this substitute part.

Q: What does RoHS Compliant versus ROHS3 Compliant mean? A: Both indicate lead-free construction. ROHS3 refers to RoHS Directive 2011/65/EU with updates (2015/863/EU, restricted substances annex). All parts listed meet current lead-free regulatory requirements.

Q: Are the backset spacing differences between 0.319" and 0.318" significant? A: The 0.001" difference (0.02mm) is within tolerance for D-Sub connectors and does not affect mating compatibility. This represents normal manufacturing variation across different connector designs.

Q: What does "Flash" contact finish thickness mean? A: Flash plating indicates a thin, non-specified thickness of plating applied to provide basic corrosion protection. This differs from the 8.00µin specification on the primary part, which provides defined plating thickness.

Q: Can these connectors be intermated? A: These are receptacle (female socket) parts. Compatibility with the mating plug is determined by shell size (all are 1/DE/E) and position count (all are 9). Receptacle-to-receptacle mating does not apply.
