Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L77DFE09SAM4 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting type: Right Angle, Through Hole
• Termination method: Solder

Electrical Performance Parameters:

• Current rating: 7.5A (primary specification; lower ratings indicate reduced capacity)
• Voltage rating: 300V (primary specification; lower ratings indicate reduced capability)
• Operating temperature range: -55°C ~ 155°C (primary specification; narrower ranges indicate reduced environmental capability)

Material and Compliance Parameters:

• Contact finish: Gold
• Material flammability rating: UL94 V-0
• RoHS compliance status

Substitute parts meeting all core compatibility parameters and maintaining equivalent or superior electrical performance are classified as direct substitutes. Parts with reduced current or voltage ratings, narrower operating temperature ranges, or different shell material finishes are identified with specific parameter deviations noted.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical and Environmental Equivalence:

The DEM09S732N (Amphenol ICC FCI) provides complete electrical and environmental equivalence to the L77DFE09SAM4. Both parts maintain 7.5A current rating, 300V voltage rating, and -55°C ~ 155°C operating temperature range. Both are RoHS compliant with UL94 V-0 flammability rating and MSL 1 classification. The DEM09S732N differs in shell material finish (yellow cadmium plated versus tin plated) and packaging format (bulk versus tray). This part is suitable for direct substitution in applications requiring identical electrical performance and environmental capability.

Reduced Electrical Performance Substitutes:

Parts 5745131-1, 5745394-2, and 5745395-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) provide reduced electrical specifications: 6A current rating and 125V voltage rating versus the primary part's 7.5A and 300V. Operating temperature range is narrowed to -55°C ~ 105°C. These parts are suitable for applications where reduced current and voltage requirements are acceptable. All three maintain RoHS compliance and UL94 V-0 flammability rating. Differences among these three parts include flange features (unthreaded housing, 4-40 threaded housing, or female screwlock) and contact finish thickness (flash or 30.0µin).

Limited Electrical Specification Substitute:

The 182-009-213R531 (NorComp Inc., 182 series) provides 5A current rating, the lowest among substitute options, with unspecified voltage rating. Operating temperature range is -55°C ~ 105°C. This part is suitable only for applications with current requirements not exceeding 5A. The part is ROHS3 compliant with UL94 V-0 flammability rating. Shell material is steel with nickel plating. Flange feature includes 4-40 threaded housing and board lock functionality.

Unspecified Current Rating Substitute:

The 5748979-1 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) does not specify current rating. Voltage rating is 125V with operating temperature range -55°C ~ 105°C. This part includes board lock feature and female screwlock flange. Selection of this part requires confirmation of current capacity from the manufacturer prior to application.

Compliance and Regulatory Status:

All substitute parts maintain active product status and RoHS compliance. Parts 5745131-1, 5745394-2, and 182-009-213R531 are ROHS3 compliant. All parts carry ECCN EAR99 and HTSUS 8536.69.4040 classifications. REACH status is unaffected for all parts except 5748979-1, which is vendor undefined.

Frequently Asked Questions (FAQ)

Q: Can the 182-009-213R531 be used as a direct replacement for the L77DFE09SAM4?

A: The 182-009-213R531 is mechanically compatible as a 9-position D-Sub receptacle with right-angle solder termination. However, it provides reduced electrical performance: 5A current rating versus 7.5A, unspecified voltage rating versus 300V, and narrower operating temperature range (-55°C ~ 105°C versus -55°C ~ 155°C). Use this part only in applications where these reduced specifications are acceptable.

Q: What is the primary difference between the TE Connectivity parts (5745131-1, 5745394-2, 5745395-2)?

A: All three TE Connectivity parts share identical electrical specifications (6A current, 125V voltage, -55°C ~ 105°C operating range). Differences are mechanical: flange feature configuration (unthreaded housing, 4-40 threaded housing, or female screwlock) and contact finish thickness (flash or 30.0µin). Selection depends on specific mounting and mating requirements.

Q: Is the DEM09S732N a full equivalent to the L77DFE09SAM4?

A: The DEM09S732N matches all critical electrical and environmental specifications: 7.5A current rating, 300V voltage rating, -55°C ~ 155°C operating temperature, gold contact finish, UL94 V-0 flammability rating, and RoHS compliance. Differences are shell material finish (yellow cadmium plated versus tin plated) and packaging (bulk versus tray). This part is suitable for direct substitution where these material and packaging differences are acceptable.

Q: Why do some substitute parts have lower voltage and current ratings?

A: Substitute parts from different manufacturers employ different design approaches and materials. The TE Connectivity AMPLIMITE HD-20 series parts are designed for 125V and 6A operation, which is lower than the Amphenol ICC design specifications of 300V and 7.5A. Selection must match application requirements.

Q: What is the significance of the backset spacing difference (0.319" versus 0.318")?

A: The backset spacing difference of 0.001" (0.02mm) is within typical manufacturing tolerance for D-Sub connectors. This minor variation does not affect mechanical compatibility or mating performance.

Q: Can the 5748979-1 be used without confirming current rating specifications?

A: No. The 5748979-1 does not specify current rating in available documentation. Prior to application, current capacity must be confirmed directly from TE Connectivity to ensure the part meets circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed maintain RoHS compliance. Parts 5745131-1, 5745394-2, and 182-009-213R531 are ROHS3 compliant. Parts 5745395-2, 5748979-1, and DEM09S732N are RoHS compliant. The L77DFE09SAM4 is RoHS compliant.

Q: What packaging formats are available?

A: The L77DFE09SAM4 and most substitute parts are supplied in tray packaging. The DEM09S732N is supplied in bulk packaging. Packaging selection may affect inventory management and component handling procedures.

Q: Does shell material finish affect electrical performance?

A: Shell material finish (tin plated, nickel plated, or yellow cadmium plated) does not affect electrical performance of the connector. Finish selection is based on environmental corrosion resistance requirements and application-specific specifications.
