DBML25P500 D-Sub Plug 25 Position Right Angle Solder Connector

Part Overview

The DBML25P500 is a 25-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This through-hole, right-angle solder connector is designed for signal applications requiring robust mechanical and electrical performance. The part is currently active in production with 934 units in stock. Equivalent and substitute parts are necessary when addressing supply chain constraints, design revisions, or when alternative manufacturers' components meet the same electrical and mechanical specifications for your application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBML25P500 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 25-position D-Sub plug with male pins, 2-row layout, shell size 3 (DB, B)
• Mounting and Termination: Through-hole, right-angle orientation with solder termination
• Electrical Performance: Current rating of 7.5A per contact (or higher) and voltage rating of 300V (or higher)
• Operating Environment: Temperature range of -55°C to 125°C (or wider)
• Material Compliance: UL94 V-0 flammability rating
• Contact and Shell Materials: Brass contacts with gold finish; steel shell with appropriate plating

The substitute parts listed below meet these core requirements. Variations in dielectric material, flange design, contact form, and shell finish do not preclude substitution when electrical and mechanical parameters remain compatible.

Engineering Selection Recommendations

DBML25P500 (Amphenol ICC / FCI): Original specification. RoHS non-compliant. Suitable for applications where legacy component specifications are required or RoHS exemptions apply.

09643247232 (HARTING): ROHS3 compliant alternative. Operates at reduced temperature range (-20°C to 125°C versus -55°C to 125°C) and lower voltage rating (100V versus 300V). Suitable for applications within the narrower environmental and electrical specifications. Features board lock, filter, grounding indents, and mounting brackets.

09663236803 (HARTING): ROHS3 compliant alternative. Maintains full temperature range (-55°C to 125°C). Voltage rating not specified. Mating side female screwlock flange. Suitable for applications requiring RoHS compliance and extended temperature operation.

09663626813 (HARTING): ROHS3 compliant alternative. Maintains full temperature range (-55°C to 125°C). Voltage rating not specified. Mating side female screwlock flange with board lock feature. Suitable for applications requiring RoHS compliance and extended temperature operation with enhanced mechanical retention.

09663636813 (HARTING): ROHS3 compliant alternative. Maintains full temperature range (-55°C to 125°C). Voltage rating not specified. Mating side female screwlock flange with board lock and grounding indents. Suitable for applications requiring RoHS compliance and extended temperature operation with enhanced mechanical retention and grounding.

5745436-3 (TE Connectivity AMP): ROHS3 compliant alternative. Operates at reduced temperature range (-55°C to 105°C versus -55°C to 125°C) and lower current rating (6A versus 7.5A per contact). Lower voltage rating (125V versus 300V). Suitable for applications within the narrower electrical specifications. Series AMPLIMITE HDP-20. Features grounding indents and mounting brackets.

Frequently Asked Questions (FAQ)

Q: Can I substitute DBML25P500 with any of the listed alternatives?

A: Substitution depends on your application's electrical and environmental requirements. All alternatives maintain the 25-position D-Sub plug configuration with male pins, through-hole right-angle solder termination, and UL94 V-0 flammability rating. However, verify that your application tolerates differences in voltage rating, current rating, operating temperature range, and RoHS compliance status before substitution.

Q: What is the primary difference between DBML25P500 and the HARTING alternatives?

A: The DBML25P500 is RoHS non-compliant with a 300V voltage rating and operates across -55°C to 125°C. The HARTING alternatives (09643247232, 09663236803, 09663626813, 09663636813) are ROHS3 compliant. Part 09643247232 has reduced voltage (100V) and temperature range (-20°C to 125°C). The remaining HARTING parts maintain the full temperature range but have unspecified voltage ratings.

Q: Is the TE Connectivity 5745436-3 a direct replacement?

A: The 5745436-3 is mechanically and functionally compatible as a 25-position D-Sub plug with male pins in right-angle solder configuration. However, it has a lower current rating (6A versus 7.5A per contact), lower voltage rating (125V versus 300V), and reduced maximum operating temperature (105°C versus 125°C). Substitution is valid only if your application operates within these lower electrical and thermal limits.

Q: Do all substitute parts have the same flange design?

A: No. The DBML25P500 features a housing/shell flange (M3). The HARTING parts 09643247232 has a housing/shell flange (4-40), while 09663236803, 09663626813, and 09663636813 feature mating side female screwlock flanges (4-40). The TE Connectivity 5745436-3 has a mating side standard screws flange. Verify mechanical compatibility with your mating connector and mounting requirements.

Q: Are there RoHS-compliant alternatives to DBML25P500?

A: Yes. All substitute parts listed (09643247232, 09663236803, 09663626813, 09663636813, and 5745436-3) are ROHS3 compliant. Select based on your specific voltage, current, and temperature requirements.

Q: What is the inventory status of these substitute parts?

A: Current inventory levels are: 09643247232 (761 units), 09663236803 (1228 units), 09663626813 (729 units), 09663636813 (1192 units), and 5745436-3 (877 units). Verify availability with your supplier for your required lead time and quantity.
