Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L17TF2510101 are identified based on strict alignment with the following core parameters that define functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Termination Method: Press-Fit
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variations in Substitute Parts:

• Mounting Type: Through Hole or Panel Mount (both support press-fit termination)
• Shell Material Finish: Steel with Tin Plated, Nickel Plated, or Tin-Nickel Plated finishes
• Contact Material: Brass or Phosphor Bronze
• Current Rating: Equal to or greater than 3A per contact
• Voltage Rating: Equal to or greater than 300V
• RoHS Compliance Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited) or Not Applicable

Substitute parts must maintain the same electrical interface (25 positions, 2 rows, DB/B shell size) and environmental specifications (temperature range, flammability rating) to ensure direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

L17TF2510101 (Primary Part): Select this part for applications requiring through-hole mounting with standard current capacity of 3A per contact. This connector is RoHS Compliant with unlimited moisture sensitivity rating, suitable for general industrial and commercial applications with standard environmental conditions.

191-025-123R001 (NorComp Inc. Substitute): This part provides equivalent electrical interface with increased current capacity of 5A per contact. The panel mount configuration offers mechanical flexibility for applications where board-edge mounting is preferred. ROHS3 compliance and nickel-plated steel shell provide enhanced corrosion resistance. Select this part when panel mounting is required or when higher current capacity provides design margin. Note: Voltage rating is not specified in available documentation.

D25P91C4GV00LF (Amphenol ICC / FCI Substitute): This part delivers the highest current capacity at 5A per contact with phosphor bronze contacts and tin-nickel plated steel shell, providing superior contact durability and corrosion resistance. Through-hole mounting maintains mechanical compatibility with the primary part. Board lock feature and mating-side female screwlock provide enhanced mechanical retention. RoHS Compliant with 300V voltage rating. Select this part for applications requiring maximum contact reliability, higher current capacity, or enhanced mechanical locking features.

All three parts maintain identical electrical interface (25 positions, 2 rows, DB/B shell size), operating temperature range (-55°C to 125°C), and UL94 V-0 flammability rating, ensuring functional equivalence in D-Sub connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 191-025-123R001 (panel mount) be used as a direct replacement for the L17TF2510101 (through-hole)?

A: The 191-025-123R001 provides electrical equivalence and maintains the same 25-position, 2-row DB/B shell size interface. However, the mounting type differs: panel mount versus through-hole. Physical board layout and mechanical mounting structure must accommodate the panel mount configuration. Electrical compatibility is confirmed; mechanical integration requires design verification.

Q: What is the significance of the higher current rating (5A) in substitute parts compared to the primary part (3A)?

A: The substitute parts D25P91C4GV00LF and 191-025-123R001 are rated for 5A per contact, compared to 3A for the L17TF2510101. This higher rating provides increased current-carrying capacity and design margin. Substitution is valid for applications operating at or below 3A per contact. Applications requiring current capacity above 3A per contact benefit from the higher-rated substitutes.

Q: Are there differences in contact material between these parts?

A: The L17TF2510101 and 191-025-123R001 use brass contacts, while the D25P91C4GV00LF uses phosphor bronze contacts. Both materials are acceptable for signal-level D-Sub connectors. Phosphor bronze provides enhanced durability and contact resistance stability over extended mating cycles. All three parts feature gold-flashed contact finish for corrosion resistance and low contact resistance.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates conformance to the original Restriction of Hazardous Substances Directive. ROHS3 Compliant indicates conformance to the updated RoHS 3 Directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. Both certifications confirm lead-free and hazardous substance restrictions. ROHS3 represents the current regulatory standard.

Q: Can these connectors be used interchangeably in existing designs?

A: Electrical and environmental specifications are equivalent across all three parts, supporting functional interchangeability within the D-Sub connector category. Physical mounting type (through-hole versus panel mount) and shell finish variations must be evaluated against specific board layout and environmental exposure requirements. Contact material and current rating differences provide design flexibility for applications with varying performance demands.

Q: What does "press-fit termination" mean for these connectors?

A: Press-fit termination is a solderless connection method where wire or PCB traces are inserted into contact cavities under controlled pressure, creating a mechanical and electrical connection. All three parts use press-fit termination, eliminating the need for solder and reducing assembly complexity. This method is suitable for automated assembly processes and provides consistent connection quality.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory levels are: L17TF2510101 (852 units), 191-025-123R001 (806 units), and D25P91C4GV00LF (1271 units). The D25P91C4GV00LF has the highest inventory availability. For high-volume production or long-term supply assurance, inventory levels should be considered alongside technical requirements and lead time commitments from suppliers.
