L717DFCH37POL2RM5 D-Sub Plug 37 Position Equivalent & Substitute Parts

Part Overview

The L717DFCH37POL2RM5 is a 37 position D-Sub plug connector manufactured by Amphenol ICC, featuring male pins, panel mount through-hole termination, and solder connection. This connector is classified as active product status with full inventory availability (1044 pcs in stock). The connector operates across an industrial temperature range of -55°C to 125°C with a current rating of 7.5A and voltage rating of 300V, making it suitable for signal transmission applications requiring robust environmental performance.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative sourcing reduces procurement costs, or when design requirements permit operation within relaxed electrical parameters. All substitute parts listed maintain core mechanical compatibility through identical 37-position configuration, 2-row layout, shell size 4 (DC, C), and solder termination method.

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFCH37POL2RM5 is determined by the following mandatory parameters:

Core Mechanical Compatibility Requirements:

37 position connector configuration
2-row layout structure
Shell size 4 (DC, C) D-Sub format
Plug connector type with male pins
Solder termination method
Through-hole mounting capability

Electrical Performance Constraints: All substitute parts operate at reduced electrical ratings compared to the main part. The L717DFCH37POL2RM5 specifies 7.5A current rating and 300V voltage rating. All listed substitute parts from TE Connectivity operate at 6A current rating and 125V voltage rating. These reduced ratings establish the upper electrical limits for substitution eligibility. Applications requiring the full 7.5A or 300V specifications cannot use these substitute parts.

Environmental Operating Range: The main part operates across -55°C to 125°C. Substitute parts operate across -55°C to 105°C, establishing a reduced upper temperature limit of 105°C for substitution applications.

Compliance and Regulatory Status: All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. RoHS compliance status varies among substitute parts and must be evaluated against specific procurement requirements.

Engineering Selection Recommendations

Primary Substitution Candidates (RoHS3 Compliant):

The following parts meet current RoHS3 compliance requirements and are recommended for new designs and procurement where regulatory compliance is mandatory:

5747375-8: TE Connectivity AMPLIMITE HD-20 series, 1347 pcs inventory, steel tin-plated shell with grounding indents, housing/shell flange with 4-40 mounting
5747375-2: TE Connectivity AMPLIMITE HD-20 series, 1547 pcs inventory, steel tin-plated shell with grounding indents, unthreaded housing/shell flange
5745074-4: TE Connectivity AMPLIMITE HD-20 series, 1128 pcs inventory, mating side female screwlock flange
5208009-1: TE Connectivity AMPLIMITE HD-20 series, 1179 pcs inventory, unthreaded housing/shell flange
5208009-3: TE Connectivity AMPLIMITE HD-20 series, 772 pcs inventory, unthreaded housing/shell flange
2-5747705-1: TE Connectivity AMPLIMITE HDP-20 series, 1481 pcs inventory, mating side female screwlock flange

Secondary Substitution Candidates (RoHS Compliant, Non-RoHS3):

The following parts maintain RoHS compliance but do not meet RoHS3 specifications:

5745074-1: TE Connectivity AMPLIMITE HD-20 series, 903 pcs inventory, mating side female screwlock flange
5745074-2: TE Connectivity AMPLIMITE HD-20 series, 1629 pcs inventory, mating side female screwlock flange

Not Recommended for New Designs:

208009-1: RoHS non-compliant status disqualifies this part from applications requiring regulatory compliance

Flange Feature Considerations:

Substitute parts differ in flange configuration from the main part. The L717DFCH37POL2RM5 features board-side 4-40 flange. Substitute parts offer three flange options: housing/shell unthreaded, housing/shell 4-40, or mating side female screwlock 4-40. Flange selection must align with mechanical mounting requirements of the target application.

Electrical Derating:

All substitute parts operate at 6A current rating and 125V voltage rating, compared to the main part's 7.5A and 300V ratings. Applications must confirm that circuit requirements do not exceed these reduced electrical specifications.

Temperature Operating Range:

All substitute parts operate to 105°C maximum, compared to the main part's 125°C maximum. Applications requiring sustained operation above 105°C cannot use these substitute parts.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part in an application designed for the L717DFCH37POL2RM5?

A: Substitution is permissible only when the application electrical requirements do not exceed 6A current and 125V voltage, and when the maximum operating temperature does not exceed 105°C. The main part's 7.5A, 300V, and 125°C specifications establish the upper limits. If your application requires any of these higher specifications, the substitute parts are not compatible.

Q: What is the difference between the various flange options on the substitute parts?

A: The L717DFCH37POL2RM5 uses a board-side 4-40 flange for panel mounting. Substitute parts offer three flange configurations: (1) housing/shell unthreaded flange for applications without threaded mounting holes, (2) housing/shell 4-40 flange for panel mounting with threaded holes, and (3) mating side female screwlock 4-40 flange for connector-to-connector locking. Select the flange type matching your mechanical mounting interface.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts are RoHS3 compliant. Part 208009-1 is RoHS non-compliant and should not be used in applications requiring regulatory compliance. For new designs, select from the RoHS3 compliant options: 5747375-8, 5747375-2, 5745074-4, 5208009-1, 5208009-3, or 2-5747705-1.

Q: What is the difference between RoHS and RoHS3 compliance?

A: RoHS3 represents the current regulatory standard with updated substance restrictions. RoHS compliant parts meet earlier RoHS requirements but may not meet current RoHS3 specifications. For procurement requiring current regulatory alignment, specify RoHS3 compliant parts.

Q: Do all substitute parts have the same contact finish specifications?

A: All substitute parts feature gold-plated contacts. The main part specifies 20.0µin (0.51µm) contact finish thickness. Most substitute parts specify flash gold finish thickness, which is thinner than the main part's specification. This difference is acceptable for signal transmission applications but may affect contact wear characteristics in high-cycle mating applications.

Q: Can I use substitute parts interchangeably in the same circuit board?

A: Yes, all substitute parts maintain identical 37-position configuration, 2-row layout, shell size 4 (DC, C), and solder termination. However, flange configuration differences require mechanical verification. If your circuit board design accommodates multiple flange types, parts are interchangeable. If your design specifies a particular flange type, select substitute parts with matching flange configuration.

Q: What inventory levels are available for substitute parts?

A: Inventory availability ranges from 624 pcs (745054-4) to 1629 pcs (5745074-2). The highest inventory availability is 5747375-2 with 1547 pcs and 5745074-2 with 1629 pcs. For large-volume procurement, these parts offer the best availability.

Q: Are there any REACH compliance differences between the main part and substitute parts?

A: The main part is REACH Unaffected. Substitute parts vary: some are REACH Unaffected, some are REACH Affected, and one is Vendor Undefined. For applications requiring REACH compliance documentation, select parts with REACH Unaffected or Vendor Undefined status, or obtain compliance documentation from the manufacturer for REACH Affected parts.

Q: What is the difference between the AMPLIMITE HD-20 and AMPLIMITE HDP-20 series?

A: Both series are TE Connectivity D-Sub plug connectors with 37-position configuration. The HDP-20 series (represented by 2-5747705-1) is a variant within the AMPLIMITE product line. Both series maintain identical electrical and mechanical compatibility for substitution purposes.
