L717DFBH25POL2 D-Sub 25 Position Plug Connector Equivalent & Substitute Parts

Part Overview

The L717DFBH25POL2 is a 25 position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins, panel mount through-hole termination via solder, and is designed for signal applications. The part is currently active in production with 765 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility. This reference provides equivalent and substitute D-Sub 25 position plug connectors that share core functional parameters with the L717DFBH25POL2.

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 25 position plug connectors is determined by the following core parameters:

Primary Compatibility Criteria:

Connector type must be plug with male pins
Position count must be 25
Row configuration must be 2 rows
Shell size and layout must be 3 (DB, B)
Termination method must be solder
Contact type must be signal

Secondary Compatibility Criteria:

Current rating must equal or exceed 7.5A
Voltage rating must equal or exceed 300V
Operating temperature range must encompass -55°C to 125°C or be compatible with application requirements

Mounting Configuration Consideration: The L717DFBH25POL2 specifies panel mount through-hole configuration. Substitute parts may include through-hole only configurations without explicit panel mount designation, provided the flange feature and physical dimensions support equivalent installation methods.

Substitute parts are grouped into two categories: direct equivalents with matching electrical and mechanical specifications, and functional substitutes with acceptable parameter variations that maintain circuit performance within design tolerances.

Engineering Selection Recommendations

Tier 1 Substitutes (Highest Compatibility):

The HARTING 09643227240 and TE Connectivity 1-5745968 series (parts 1-5745968-3, 1-5745968-4, 1-5745968-5, 1-5745968-6) represent the most suitable substitutes. These parts maintain the core D-Sub 25 position plug configuration with solder termination and UL94 V-0 flammability rating. The TE Connectivity AMPLIMITE HD-20 series parts are actively produced with substantial inventory availability (1442 to 3136 units per variant) and carry ROHS3 compliance certification.

Voltage and Current Considerations:

The L717DFBH25POL2 specifies 300V and 7.5A ratings. Substitute parts with lower voltage ratings (100V to 125V) are suitable for applications operating within those voltage envelopes. The HARTING 09643227240 maintains 7.5A current rating. TE Connectivity and NorComp alternatives provide 6A or lower current ratings, which are acceptable for applications not requiring the full 7.5A capacity.

Temperature Range Compatibility:

The L717DFBH25POL2 operates across -55°C to 125°C. The HARTING 09653617713 and TE Connectivity 1-5745968 series maintain this full temperature range. The HARTING 09643227240 operates from -20°C to 125°C, which is suitable for applications not requiring the -55°C lower limit. NorComp parts operate from -50°C to 100°C, which is acceptable for applications within these boundaries.

Mounting Configuration:

The L717DFBH25POL2 specifies panel mount through-hole configuration. Direct panel mount equivalents include NorComp 172-025-112R001 and 172-E25-113R911. TE Connectivity and HARTING through-hole only variants require verification of flange feature compatibility with the intended panel mount application.

Compliance and Regulatory Status:

All substitute parts carry UL94 V-0 flammability certification. RoHS compliance is confirmed across all active parts. REACH status varies: most parts are REACH Unaffected or ROHS3 Compliant. TE Connectivity parts 2-338311-2 and 2-5747704-0 are marked as REACH Affected, requiring evaluation against specific application regulatory requirements.

Product Status Consideration:

NorComp 172-025-112R001 is marked as obsolete. While inventory is available (2444 units), this part should be considered only for replacement or repair applications where design continuity is required. All other substitute parts maintain active production status.

Frequently Asked Questions (FAQ)

Q: Can I substitute a TE Connectivity 1-5745968-3 for the L717DFBH25POL2 in my application?

A: The 1-5745968-3 is compatible if your application operates within 125V and 6A limits, and does not require the full -55°C to 125°C temperature range (this part operates to 105°C maximum). Both parts share the 25 position D-Sub plug configuration, solder termination, and UL94 V-0 rating. Verify that the through-hole mounting configuration with mating side female screwlock flange is compatible with your panel mount requirement.

Q: What is the difference between the HARTING 09643227240 and 09653617713?

A: Both are HARTING 25 position D-Sub plugs with solder termination. The 09643227240 provides 7.5A current rating and operates from -20°C to 125°C with a housing/shell unthreaded flange. The 09653617713 provides 6.5A current rating, operates from -55°C to 125°C, and features a mating side female screwlock flange. Select based on your current requirements and temperature range needs.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed carry RoHS compliance certification (either RoHS Compliant or ROHS3 Compliant). The obsolete NorComp 172-025-112R001 is ROHS3 Compliant. Two TE Connectivity parts (2-338311-2 and 2-5747704-0) are marked as REACH Affected, which requires evaluation against your specific regulatory requirements.

Q: Can I use a substitute part with a lower current rating than the L717DFBH25POL2?

A: Yes, if your circuit design operates at or below the substitute part's current rating. The L717DFBH25POL2 is rated for 7.5A. Substitute parts rated for 6A, 6.5A, or 5A are acceptable for applications drawing current within those limits. Do not use a substitute part with a lower current rating in applications requiring the full 7.5A capacity.

Q: What is the significance of the contact finish thickness specification?

A: The L717DFBH25POL2 specifies 20.0µin (0.51µm) gold contact finish thickness. Substitute parts with flash gold plating or unspecified thickness may have different contact resistance characteristics and wear properties. For applications with stringent contact resistance requirements or high-cycle mating operations, verify that the substitute part's contact finish specification meets your performance criteria.

Q: Why do some substitute parts not specify voltage rating?

A: Voltage rating specifications are not provided for all substitute parts in the available data. This does not indicate inadequate voltage performance. For applications requiring specific voltage ratings, contact the manufacturer directly or consult the detailed product datasheet. The L717DFBH25POL2 specifies 300V; substitute parts with specified ratings of 100V to 125V are suitable for lower voltage applications.

Q: Is the NorComp 172-025-112R001 still available despite being marked obsolete?

A: The part is listed with 2444 units in stock, indicating current availability. However, obsolete status means the manufacturer is not actively producing new units. This part is suitable for replacement or repair applications where design continuity is required, but should not be selected for new designs. Prefer active production alternatives for long-term supply assurance.

Q: What mounting configuration differences exist between substitute parts?

A: The L717DFBH25POL2 specifies panel mount through-hole with board side 4-40 flange. Substitute parts vary: NorComp parts include explicit panel mount designation; TE Connectivity and HARTING parts specify through-hole with different flange features (housing/shell, mating side female screwlock, or board side M3). Verify that the flange feature and physical dimensions of the substitute part are compatible with your panel mount installation method.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: Yes, provided each part meets the electrical and mechanical requirements of its specific connector position. All listed substitute parts share the 25 position D-Sub plug configuration with solder termination. However, for consistency in assembly, testing, and maintenance, using parts from a single manufacturer or product series is recommended.
