DEP09S364TLF D-Sub 9 Position Receptacle Connector

Part Overview

The DEP09S364TLF is a 9 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the DP series. This through-hole solder termination connector features female sockets with gold-plated contacts and is designed for signal applications requiring 1000V voltage rating and 7.5A per contact current capacity. The part is currently active in production with 961 units in stock.

Equivalent and substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements permit alternative configurations such as panel mount options or different contact materials while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEP09S364TLF is determined by the following core parameters that must remain consistent:

• Connector Style & Type: D-Sub receptacle with female sockets
• Position Count & Shell Size: 9 positions in DE/E shell size (1)
• Number of Rows: 2 rows
• Termination Method: Solder termination
• Contact Type: Signal contacts
• Electrical Ratings: Voltage and current capacity sufficient for application requirements
• Compliance: RoHS status and material flammability rating (UL94 V-0)

The substitute part 172-009-212R911 (NorComp Inc., M Series) qualifies as an equivalent because it maintains the same connector style, position count, shell size, row configuration, and solder termination. However, this substitute introduces variations in mounting type (panel mount capability), contact material (brass vs. copper alloy), current rating (5A vs. 7.5A), and operating temperature range (-50°C to 100°C vs. -55°C to 125°C). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The DEP09S364TLF remains the preferred selection for new designs and active production due to its active product status, higher current rating (7.5A vs. 5A), extended operating temperature range (-55°C to 125°C vs. -50°C to 100°C), and RoHS Compliant certification.

The 172-009-212R911 substitute is classified as obsolete and should be considered only when the DEP09S364TLF is unavailable and application requirements fall within its reduced electrical and thermal specifications. The lower current rating of 5A per contact and narrower operating temperature range represent functional limitations that must be verified against circuit requirements. The panel mount capability of the substitute may provide mechanical advantages in certain enclosure designs but does not offset its obsolete status for new applications.

Both parts maintain UL94 V-0 flammability rating and solder termination compatibility. The choice between copper alloy (main part) and brass (substitute) contact materials does not present a compatibility barrier for standard signal applications.

Frequently Asked Questions (FAQ)

Q: Can the 172-009-212R911 be used as a direct replacement for the DEP09S364TLF?

A: Mechanical and electrical compatibility exists for the core connector interface (9 positions, DE/E shell, solder termination). However, the substitute's reduced current rating (5A vs. 7.5A) and narrower operating temperature range (-50°C to 100°C vs. -55°C to 125°C) require verification against application specifications. The obsolete status of the substitute makes it unsuitable for new designs.

Q: What are the key differences in mounting between these parts?

A: The DEP09S364TLF is configured for through-hole mounting only. The 172-009-212R911 offers both panel mount and through-hole options, providing additional mechanical flexibility for certain enclosure configurations.

Q: Are there compliance differences between these connectors?

A: Both parts are RoHS compliant (DEP09S364TLF: RoHS Compliant; 172-009-212R911: ROHS3 Compliant) and maintain UL94 V-0 flammability rating. The substitute includes REACH Unaffected status, while the main part does not specify REACH compliance in the provided data.

Q: What is the impact of the contact material difference?

A: The main part uses copper alloy contacts while the substitute uses brass contacts. Both materials are suitable for gold-plated signal applications and do not present compatibility issues for standard D-Sub mating cycles.

Q: Why is the substitute listed as obsolete?

A: The 172-009-212R911 has reached end-of-life status with NorComp Inc. While inventory may remain available through distribution channels, new production is not available. The DEP09S364TLF should be specified for designs requiring long-term supply assurance.
