DC37S065T D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DC37S065T is a 37-position D-Sub receptacle connector with female sockets manufactured by Amphenol ICC (FCI). This connector is designed for signal applications in D-Sub configurations and is currently in active production status. The part is available in new original inventory (642 pcs in stock).

Finding equivalent and substitute parts is necessary to ensure supply chain continuity, optimize procurement across different packaging formats, and maintain design flexibility when the primary part number becomes unavailable or when alternative termination methods are required for specific assembly processes.

Key Parameters

Substitute Part Grouping Explanation

The DC37S065T has one direct substitute part: DC37S065TLF. This substitution is valid based on the following critical parameters that remain constant across both parts:

• Connector Type & Configuration: Both are 37-position D-Sub receptacles with female sockets
• Electrical Specifications: Identical signal contact type, voltage rating (300V), and current rating (5A per contact)
• Mechanical Compatibility: Same shell size (4/DC, C), number of positions (37), and number of rows (2)
• Material & Environmental Compliance: Both use steel shells with tin plating, gold-plated contacts (GXT™), and meet UL94 V-0 flammability requirements
• Operating Conditions: Identical operating temperature range (-55°C ~ 125°C)
• Regulatory Compliance: Both are RoHS Compliant and REACH Affected

The primary difference between these parts is the termination method and packaging format. The DC37S065T uses solder cup termination, while DC37S065TLF also uses solder cup termination but is supplied in tray packaging rather than bulk format.

Parameter Comparison

Engineering Selection Recommendations

Both DC37S065T and DC37S065TLF are functionally equivalent for signal applications requiring 37-position D-Sub receptacle connectors. Selection between these parts should be based on the following criteria:

DC37S065T is appropriate when bulk packaging is preferred or when existing procurement specifications reference this exact part number.

DC37S065TLF is appropriate when tray packaging is required for automated assembly processes or when tray packaging aligns with manufacturing workflow requirements. This part number also has higher current inventory availability (863 pcs vs. 642 pcs).

Both parts meet identical electrical, mechanical, and environmental specifications. Both are RoHS Compliant and REACH Affected, with UL94 V-0 flammability certification. Both operate across the full temperature range of -55°C to 125°C and support 5A per contact at 300V.

Frequently Asked Questions (FAQ)

Q: Are DC37S065T and DC37S065TLF electrically interchangeable?

A: Yes. Both parts are 37-position D-Sub receptacles with identical electrical ratings (300V, 5A per contact), contact materials (copper alloy with gold GXT™ finish), and signal contact type. They can be used interchangeably in circuit designs.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. DC37S065T is supplied in bulk packaging, while DC37S065TLF is supplied in tray packaging. Both use identical solder cup termination and are manufactured by Amphenol ICC (FCI).

Q: Can I substitute DC37S065TLF for DC37S065T in my assembly process?

A: Yes, provided your assembly equipment can accommodate tray packaging. The connector itself is mechanically and electrically identical. Verify that your pick-and-place or manual assembly process is compatible with tray-packaged components.

Q: Are both parts RoHS compliant?

A: Yes. Both DC37S065T and DC37S065TLF are RoHS Compliant and REACH Affected, meeting current environmental regulations for electronic components.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, suitable for industrial and commercial applications requiring extended temperature performance.

Q: Do these connectors require any special handling?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures during storage or handling.
