DDML50P300 D-Sub 50 Position Plug Connector - Equivalent & Substitute Parts

Part Overview

The DDML50P300 is a 50 position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This through-hole solder termination connector features male pins with a 3-row configuration in shell size 5 (DD, D) layout. The connector is rated for 7.5A at 300V with an operating temperature range of -55°C to 155°C and carries UL94 V-0 material flammability certification. Currently in active production status with 879 units in stock, this connector serves as a standard interface component in industrial and commercial applications. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and compatibility options for applications where the primary part may be unavailable or where specific performance parameters require adjustment.

Substitute Part Grouping Explanation

Substitution eligibility for the DDML50P300 is determined by strict alignment with the following core parameters: connector type (plug, male pins), number of positions (50), number of rows (3), shell size and layout (5 DD, D), mounting type (through hole), and termination method (solder). All identified substitute parts match these fundamental specifications, ensuring mechanical and electrical compatibility at the connector interface level.

The substitute parts are grouped into two categories based on compliance and performance characteristics:

Category 1: TE Connectivity AMPLIMITE HD-20 Series (208010-2 and 5208010-2) — These parts maintain identical mechanical configuration and contact material (brass with gold finish). Both operate within reduced electrical parameters (6A current rating, 125V voltage rating) and narrower temperature range (-55°C to 105°C) compared to the main part. The distinction between these two TE parts is RoHS compliance status: 208010-2 is RoHS non-compliant, while 5208010-2 is RoHS compliant.

Category 2: Amphenol ICC SD Series (L717SDDH50POL2RM8) — This part maintains the same manufacturer family (Amphenol ICC) with identical mechanical positioning and solder termination. It features enhanced mechanical features (board lock, grounding indents) and operates at reduced current rating (3A) with intermediate voltage rating (250V) and temperature range (-55°C to 125°C). This part is RoHS compliant.

All substitute parts share the same shell material category requirements, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1).

Engineering Selection Recommendations

Selection among the DDML50P300 and its substitute parts must be based on application-specific electrical requirements and regulatory compliance mandates.

For applications requiring maximum electrical performance: The DDML50P300 remains the primary choice, offering the highest current rating (7.5A) and voltage rating (300V) with the widest operating temperature range (-55°C to 155°C). This part is suitable for high-power signal distribution and industrial environments with extended temperature excursions.

For RoHS-compliant designs: The 5208010-2 (TE Connectivity) and L717SDDH50POL2RM8 (Amphenol ICC) are the only substitute options meeting RoHS compliance requirements. The 5208010-2 provides the closest electrical performance match to the main part within RoHS constraints (6A, 125V), while the L717SDDH50POL2RM8 offers additional mechanical features (board lock, grounding indents) at reduced electrical ratings (3A, 250V).

For non-RoHS applications with reduced electrical requirements: The 208010-2 (TE Connectivity, non-compliant) provides an alternative with 6A current rating and 125V voltage rating, suitable for lower-power signal applications.

For supply chain flexibility: All substitute parts maintain active production status with higher inventory levels (1164–1374 units) compared to the main part (879 units), providing improved availability for procurement planning.

All substitute parts carry identical UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1), ensuring compliance with standard industrial safety and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 208010-2 or 5208010-2 be used as direct replacements for the DDML50P300?

A: Both TE Connectivity parts are mechanically compatible as direct replacements at the connector interface level. However, they operate at reduced electrical ratings (6A vs. 7.5A current; 125V vs. 300V voltage) and narrower temperature range (-55°C to 105°C vs. -55°C to 155°C). Substitution is valid only if the application electrical requirements fall within these reduced parameters.

Q: What is the difference between 208010-2 and 5208010-2?

A: Both parts are identical in mechanical configuration, electrical ratings, and performance characteristics. The sole difference is regulatory compliance: 208010-2 is RoHS non-compliant, while 5208010-2 is RoHS compliant. Selection depends on whether the end application or regional market requires RoHS compliance certification.

Q: Is the L717SDDH50POL2RM8 suitable for high-current applications?

A: No. The L717SDDH50POL2RM8 is rated for 3A maximum current, significantly lower than the DDML50P300 (7.5A) and the TE Connectivity alternatives (6A). This part is appropriate only for signal-level applications with current requirements below 3A. It is not suitable for power distribution or high-current signal paths.

Q: Do all substitute parts use the same solder termination process?

A: Yes. All substitute parts employ solder termination identical to the DDML50P300, ensuring compatibility with standard PCB assembly processes and reflow soldering profiles.

Q: What are the packaging differences among these parts?

A: The DDML50P300 and L717SDDH50POL2RM8 are supplied in trays, while both TE Connectivity parts (208010-2 and 5208010-2) are supplied in tubes. Packaging affects handling, storage, and bulk ordering considerations but does not impact electrical or mechanical performance.

Q: Are all substitute parts certified to UL94 V-0?

A: Yes. All substitute parts carry UL94 V-0 material flammability certification, matching the main part specification and meeting standard industrial safety requirements.

Q: Which substitute part offers the best compliance profile for modern applications?

A: The 5208010-2 combines RoHS compliance with the highest electrical performance among compliant alternatives (6A, 125V). The L717SDDH50POL2RM8 also offers RoHS compliance but with significantly reduced current rating (3A), making it suitable only for signal-level applications.
