DAM15S300Z D-Sub 15 Position Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The DAM15S300Z is a 15 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the DM series. This vertical solder mount connector features female sockets and is designed for signal applications requiring 300V rating and 7.5A per contact capacity. The part is currently in active inventory with 870 pieces available.

Equivalent and substitute parts are necessary when the original DAM15S300Z becomes unavailable, when design requirements shift between vertical and panel mount configurations, or when alternative material finishes and compliance certifications are required for specific applications.

Engineering Selection Recommendations

Direct Vertical Mount Equivalents (Preferred for Pin-Compatible Replacement):

DAM15S300 (Amphenol ICC, DM HE501 series) is the primary equivalent. It maintains identical mounting orientation, current rating (7.5A), voltage rating (300V), and operating temperature range (-55°C to 125°C). Both parts share RoHS non-compliant status. This part is recommended when maintaining the exact same PCB footprint and mechanical orientation is required.

L77DAH15SU (Amphenol ICC Commercial Products, D series) provides vertical mount compatibility with 7.5A current rating and 300V voltage rating. It features board-side flange mounting and RoHS compliance. This part is suitable for applications requiring RoHS compliance while maintaining vertical orientation.

1757828-2 (TE Connectivity Aerospace, Defense and Marine, AMPLIMITE 109 series) is a military-grade equivalent per MIL-DTL-24308. It maintains vertical through-hole mounting and -55°C to 125°C operating temperature. Current rating is 5A, which is lower than the original part. This part is specified for aerospace, defense, and marine applications requiring military qualification.

Panel Mount Alternatives (For Design Flexibility):

NorComp Inc. 172 series (172-015-212R001, 172-015-212R911) and 172-E series (172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, 172-E15-213R911) provide panel mount configurations with board-side and mating-side flange options. These parts feature 5A current rating and -50°C to 100°C operating temperature. The 172-E series is active and ROHS3 compliant, while the 172 series is obsolete. Panel mount variants are suitable for applications where the connector mounts directly to an enclosure or panel rather than vertically on a PCB.

Compliance Considerations:

For applications requiring RoHS compliance, select L77DAH15SU (RoHS Compliant) or any 172-E series part (ROHS3 Compliant). The original DAM15S300Z and DAM15S300 are RoHS non-compliant and should be replaced with compliant alternatives in new designs subject to RoHS regulations.

For applications requiring military qualification, 1757828-2 meets MIL-DTL-24308 specification and is suitable for aerospace, defense, and marine environments.

Frequently Asked Questions (FAQ)

Q: Can I substitute a panel mount connector for the vertical mount DAM15S300Z?

A: Panel mount connectors from the NorComp 172 and 172-E series share the same 15-position D-Sub receptacle configuration and solder termination. However, they require different PCB layout and mounting hole patterns. Substitution is possible only if your design accommodates panel mount flange geometry and board-side or mating-side screw holes (4-40 thread).

Q: What is the difference between the 172-015-212R911 and 172-E15-213R911 parts?

A: Both parts feature board-side and mating-side female screwlock flanges (4-40) and are panel mount configurations. The primary differences are: 172-015-212R911 is obsolete with tin-plated steel shell and beige color; 172-E15-213R911 is active with nickel-plated steel shell, white color, and ROHS3 compliance. The 172-E series is recommended for new designs.

Q: Does the 1757828-2 military connector have the same current rating as DAM15S300Z?

A: No. The 1757828-2 is rated for 5A per contact, while DAM15S300Z is rated for 7.5A per contact. If your application requires 7.5A per contact, the 1757828-2 is not suitable. Select DAM15S300, L77DAH15SU, or maintain the original DAM15S300Z.

Q: Are the NorComp 172 series parts still available for new designs?

A: The 172-015-212R001 and 172-015-212R911 are marked as obsolete. For new designs requiring panel mount D-Sub 15-position receptacles, use the active 172-E series (172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, or 172-E15-213R911).

Q: What is the difference between board-side and mating-side flange features?

A: Board-side flange (4-40) mounting holes are located on the side facing the PCB, allowing the connector to be secured to the board. Mating-side flange (4-40) mounting holes are on the side facing the mating connector, allowing external panel or enclosure mounting. Unthreaded housing/shell variants have no flange holes and rely on solder termination alone for mechanical retention.

Q: Can I use L77DAH15SU as a direct replacement for DAM15S300Z?

A: L77DAH15SU is mechanically and electrically compatible as a vertical mount through-hole connector with matching 15-position D-Sub receptacle configuration. However, it features a board-side flange (4-40) mounting holes, while DAM15S300Z has an unthreaded housing. If your PCB layout does not accommodate the flange holes, mechanical modification or board redesign is required. Electrically, both parts support 7.5A, 300V, and -55°C to 125°C operation.

Q: What does RoHS non-compliant mean for the DAM15S300Z?

A: RoHS non-compliant indicates the part may contain restricted substances such as lead, cadmium, or hexavalent chromium. The yellow cadmium plating on DAM15S300Z is a restricted substance under RoHS regulations. For applications subject to RoHS directives (EU, California, or customer requirements), substitute with RoHS-compliant alternatives such as L77DAH15SU or the 172-E series.
