L717DD50POL2 Equivalent & Substitute Parts

Part Overview

The L717DD50POL2 is a 50-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features male pins in a DD shell size (5) configuration with three rows of contacts. The connector is designed for signal applications requiring 300V operation and 7.5A current capacity per contact across an operating temperature range of -55°C to 125°C. The part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design alternatives while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DD50POL2 is determined by strict alignment of the following critical parameters: connector style (D-Sub), connector type (Plug, Male Pins), number of positions (50), number of rows (3), shell size (5/DD), mounting type (through hole), termination method (solder), contact type (signal), material flammability rating (UL94 V-0), contact material (brass), and contact finish (gold). Voltage rating, current rating, and operating temperature range establish the electrical performance envelope within which substitutes must operate. All identified substitute parts meet these core mechanical and electrical criteria. Variations in secondary parameters such as packaging format, shell material finish, contact finish thickness specification, dielectric material composition, and regulatory compliance status are noted but do not preclude substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

L717DD50POL2 (Primary Part): This connector is the baseline reference. It maintains active product status with full RoHS compliance and REACH unaffected status. The 300V/7.5A rating and -55°C to 125°C operating range establish the maximum electrical and thermal performance envelope.

5208010-2 (TE Connectivity AMPLIMITE HD-20): This substitute provides full mechanical compatibility with identical shell size, position count, row configuration, and through-hole solder termination. The part achieves RoHS compliance and REACH unaffected status, matching the regulatory profile of the primary part. The 125V/6A rating and -55°C to 105°C operating range represent reduced electrical and thermal performance compared to the primary part. This substitute is suitable for applications operating within its specified voltage, current, and temperature limits.

208010-2 (TE Connectivity AMPLIMITE HD-20): This substitute provides identical mechanical configuration to 5208010-2 with equivalent electrical ratings (125V/6A, -55°C to 105°C). However, this part carries RoHS non-compliant and REACH affected status. Selection of this part requires verification of regulatory requirements for the end application.

DDMS50P300 (Amphenol ICC/FCI DM HE501): This substitute maintains the 300V/7.5A electrical rating and -55°C to 125°C operating range of the primary part, providing equivalent performance envelope. Mechanical compatibility is confirmed through identical shell size, position count, row configuration, and solder termination. The part carries RoHS non-compliant status. The flange feature differs (board side versus housing/shell unthreaded), which may affect mechanical mounting compatibility depending on application design. Selection requires verification of flange mounting requirements and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can 208010-2 or 5208010-2 be used as direct replacements for L717DD50POL2 in high-voltage applications?

A: No. The 208010-2 and 5208010-2 are rated for 125V maximum, while the L717DD50POL2 is rated for 300V. These substitutes are suitable only for applications operating at 125V or below. Applications requiring 300V operation must use L717DD50POL2 or DDMS50P300.

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

A: Both parts are mechanically and electrically identical (125V/6A, -55°C to 105°C, AMPLIMITE HD-20 series). The primary difference is regulatory compliance: 5208010-2 is RoHS compliant and REACH unaffected, while 208010-2 is RoHS non-compliant and REACH affected. Selection depends on application regulatory requirements.

Q: Is DDMS50P300 a suitable substitute for applications requiring 300V and 7.5A?

A: DDMS50P300 meets the 300V/7.5A electrical requirements and -55°C to 125°C operating range. However, the flange feature differs (board side versus housing/shell unthreaded). Mechanical mounting compatibility must be verified for the specific application design before substitution.

Q: What packaging differences exist among these parts?

A: L717DD50POL2 and DDMS50P300 are supplied in trays. 208010-2 and 5208010-2 are supplied in tubes. Packaging format affects handling, storage, and assembly processes but does not affect electrical or mechanical connector performance.

Q: Are all substitute parts RoHS compliant?

A: No. L717DD50POL2 and 5208010-2 are RoHS compliant. 208010-2 and DDMS50P300 are RoHS non-compliant. Applications subject to RoHS requirements must use L717DD50POL2 or 5208010-2.

Q: Can these connectors be used interchangeably in the same circuit board design?

A: Mechanical and electrical interchangeability depends on application-specific requirements. All parts share identical shell size (5/DD), position count (50), row configuration (3), and solder termination. Voltage, current, and temperature operating ranges must be verified against application requirements. Flange mounting type differences (DDMS50P300 board side versus others housing/shell unthreaded) may require design modification.

Q: What is the current rating difference between L717DD50POL2 and the TE Connectivity substitutes?

A: L717DD50POL2 and DDMS50P300 are rated for 7.5A per contact. 208010-2 and 5208010-2 are rated for 6A per contact. Applications requiring current levels between 6A and 7.5A must use L717DD50POL2 or DDMS50P300.

Q: What is the operating temperature difference between these parts?

A: L717DD50POL2 and DDMS50P300 operate across -55°C to 125°C. 208010-2 and 5208010-2 operate across -55°C to 105°C. Applications requiring operation above 105°C must use L717DD50POL2 or DDMS50P300.
