Key Parameters

Substitute Part Grouping Explanation

The substitute parts DEP09S064TLF and DEP09S065TLF are Amphenol ICC (FCI) series connectors that share critical parameters with the L77DFE09S1ACH, enabling functional substitution in specific contexts. Substitution eligibility is determined by the following matched parameters:

Matched Parameters Enabling Substitution:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Contact type: Signal
• Shell material and finish: Steel, Tin Plated
• Contact material: Copper Alloy
• Contact finish: Gold-based
• Material flammability rating: UL94 V-0
• Current rating: 7.5A per contact
• RoHS compliance: RoHS Compliant
• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99

Key Differences Affecting Substitution Scope:

• Mounting type differs: L77DFE09S1ACH is panel mount, through-hole, right-angle; substitutes are free hanging (in-line)
• Termination method differs: L77DFE09S1ACH uses solder; substitutes use solder cup
• Voltage rating differs: L77DFE09S1ACH is rated 300V; substitutes are rated 1000V
• Operating temperature upper limit differs: L77DFE09S1ACH operates to 155°C; substitutes operate to 125°C
• Contact finish specifications differ in thickness and coating variants

These differences establish that DEP09S064TLF and DEP09S065TLF are functional substitutes only where mounting configuration and termination method changes are acceptable.

Parameter Comparison

Engineering Selection Recommendations

L77DFE09S1ACH Selection Criteria: The L77DFE09S1ACH is the appropriate choice for applications requiring panel-mount, through-hole solder termination with right-angle orientation. Its active product status and RoHS compliance support modern supply chain requirements. The 300V voltage rating and 155°C maximum operating temperature accommodate standard industrial signaling applications.

DEP09S064TLF and DEP09S065TLF Selection Criteria: These substitutes are applicable when free-hanging, in-line mounting orientation and solder cup termination are acceptable for the target application. Both parts maintain RoHS compliance and UL94 V-0 flammability certification. The 1000V voltage rating provides enhanced electrical safety margin in high-voltage environments. However, the 125°C maximum operating temperature ceiling may restrict use in applications exceeding this thermal requirement. Packaging differences (DEP09S064TLF in tray; DEP09S065TLF in bulk) accommodate varying production and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can DEP09S064TLF or DEP09S065TLF directly replace L77DFE09S1ACH in existing designs? A: Direct mechanical replacement is not possible. The main part features panel-mount, through-hole, right-angle solder termination, while the substitutes are free-hanging, in-line solder cup connectors. Design-level modifications are required for successful substitution.

Q: What are the primary electrical differences between these parts? A: The voltage ratings differ significantly: L77DFE09S1ACH is rated 300V, while DEP09S064TLF and DEP09S065TLF are rated 1000V. All three support identical 7.5A current per contact. Operating temperature ranges differ by 30°C at the upper limit.

Q: Do all three parts meet RoHS and UL94 V-0 requirements? A: Yes. All three parts are RoHS Compliant with UL94 V-0 material flammability ratings, satisfying modern regulatory and safety standards.

Q: What is the difference between DEP09S064TLF and DEP09S065TLF? A: These parts are electrically and functionally identical. The primary differences are packaging (DEP09S064TLF supplied in trays; DEP09S065TLF supplied in bulk) and contact finish thickness specification (DEP09S064TLF flash; DEP09S065TLF 30.0µin / 0.76µm).

Q: Are the solder cup terminals compatible with through-hole solder joints? A: Solder cup terminals accept wire insertion and are designed for solder-filled joint formation. This differs from the direct PCB through-hole solder termination of the main part, requiring distinct assembly processes.

Q: Do all parts share the same 9-position, 2-row DE/E shell layout? A: Yes. All three parts feature identical 9-position, 2-row configuration with shell size and layout designation 1 (DE, E), ensuring mating connector compatibility.
