Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717DFB25P is determined by strict equivalence across the following critical parameters: connector style (D-Sub), connector type (plug with male pins), position count (25), row configuration (2), shell size and layout (3/DB/B), termination method (solder cup), shell material and finish (steel, tin plated), contact finish (gold), voltage rating (300V), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0).

The substitute parts DB25P064TXLF, DB25P064HTXLF, DB25P065TXLF, and DB25P065HTXLF meet these core electrical and mechanical requirements. Differences in mounting type (free hanging versus panel mount), packaging format (bulk or tray versus bag), contact finish thickness, and current rating per contact do not preclude substitution when application requirements permit alternative mounting configurations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and RoHS compliance, ensuring regulatory alignment with the original L717DFB25P. The DB25P064TXLF and DB25P064HTXLF variants provide equivalent electrical performance with flash gold contact finish, suitable for applications where contact finish thickness variation is acceptable. The DB25P065TXLF and DB25P065HTXLF variants offer enhanced contact durability through GXT™ gold plating at 30.0µin thickness, exceeding the original specification of 20.0µin.

Selection between substitute parts depends on application-specific requirements regarding mounting configuration. The L717DFB25P panel mount design differs from the free hanging (in-line) configuration of all substitute parts. Applications requiring panel mount installation must retain the L717DFB25P. Applications permitting free hanging installation may select substitute parts based on packaging availability, inventory levels, and contact finish specifications.

The DB25P065TXLF provides the highest inventory availability (1,043 units) with enhanced contact finish specifications and REACH Unaffected status. The DB25P064TXLF offers 2,697 units in stock with flash gold finish and REACH Affected status. Both DB25P064HTXLF and DB25P065HTXLF include shielding features not present in the original specification.

Frequently Asked Questions (FAQ)

Q: Can DB25P064TXLF substitute for L717DFB25P in all applications?

A: DB25P064TXLF meets all core electrical and mechanical parameters including connector style, position count, shell size, termination method, voltage rating, and operating temperature. However, the mounting type differs: L717DFB25P is panel mount while DB25P064TXLF is free hanging (in-line). Substitution is valid only for applications that do not require panel mount installation.

Q: What is the difference between DB25P064 and DB25P065 series?

A: Both series are 25 position D-Sub plugs with equivalent electrical specifications. The primary difference is contact finish thickness: DB25P064 variants feature flash gold finish, while DB25P065 variants feature 30.0µin (0.76µm) GXT™ gold plating. DB25P065 provides enhanced contact durability and corrosion resistance.

Q: Does the flash gold finish on DB25P064 variants meet the same performance requirements as the 20.0µin finish on L717DFB25P?

A: Flash gold finish and 20.0µin gold finish are distinct specifications. Flash finish provides minimal gold plating thickness for cost efficiency. The 20.0µin specification on L717DFB25P provides greater contact durability. Selection between these finishes depends on application requirements for contact wear resistance and service life.

Q: Are the shielded variants (DB25P064HTXLF and DB25P065HTXLF) compatible with unshielded applications?

A: Shielded variants include grounding indents and shielding features not present in the original L717DFB25P specification. Shielded connectors are mechanically and electrically compatible with unshielded applications but provide additional electromagnetic interference protection. Shielding does not preclude substitution in applications where the original connector is unshielded.

Q: What packaging formats are available for substitute parts?

A: L717DFB25P is supplied in bag packaging (878 units in stock). DB25P064TXLF and DB25P064HTXLF are supplied in bulk packaging (2,697 and 1,603 units respectively). DB25P065TXLF and DB25P065HTXLF are supplied in tray packaging (1,043 and 832 units respectively). Packaging format does not affect connector performance or compatibility.

Q: Is REACH compliance status a factor in substitution decisions?

A: DB25P064TXLF, DB25P064HTXLF, and DB25P065HTXLF are REACH Affected. DB25P065TXLF is REACH Unaffected. Applications subject to REACH regulations should prioritize DB25P065TXLF. Applications without REACH requirements may select any substitute part based on other performance criteria.

Q: What is the current rating difference between L717DFB25P and substitute parts?

A: L717DFB25P is rated at 7.5A total current. Substitute parts are rated at 5A per contact. Applications requiring the full 7.5A capacity of the original connector must retain L717DFB25P. Applications operating at or below 5A per contact may use substitute parts without current rating limitations.
