Engineering Selection Recommendations

Primary Part Selection (L717DB25PAM4): The L717DB25PAM4 maintains active product status with established inventory availability (856 units). This part delivers the specified 7.5A current rating and 300V voltage rating with an operating temperature range of -55°C to 125°C. RoHS compliance and UL94 V-0 flammability certification support deployment in regulated environments. The tin-plated steel shell with gold-plated brass contacts provides corrosion resistance suitable for industrial applications.

Substitute Part Selection (182-025-113R171): The 182-025-113R171 qualifies as a functional substitute when primary sourcing is constrained. This part maintains equivalent D-Sub 25-position configuration, solder termination, and UL94 V-0 certification. ROHS3 compliance exceeds RoHS requirements. However, engineering selection must account for documented parameter reductions: current rating of 5A (versus 7.5A) and maximum operating temperature of 105°C (versus 125°C). The nickel-plated steel shell and flash gold contact finish provide acceptable corrosion protection. Dielectric material composition differs (polyamide PA9T versus glass-filled thermoplastic), which may affect mechanical properties in specific thermal or mechanical stress environments.

Selection Criteria:

• Use L717DB25PAM4 for applications requiring full 7.5A current capacity or operation above 105°C
• Use 182-025-113R171 when current requirements do not exceed 5A and operating temperature remains below 105°C
• Both parts satisfy 25-position D-Sub through-hole right-angle solder applications with equivalent mechanical fit and electrical interface compatibility

Frequently Asked Questions (FAQ)

Q: Can the 182-025-113R171 directly replace the L717DB25PAM4 in all applications?

A: Direct replacement is application-dependent. Both connectors share identical D-Sub 25-position configuration, shell size, and solder termination. However, the 182-025-113R171 has a reduced current rating (5A versus 7.5A) and lower maximum operating temperature (105°C versus 125°C). Replacement is suitable only when application current requirements do not exceed 5A and operating temperature remains below 105°C.

Q: What are the mechanical compatibility considerations?

A: Both connectors feature equivalent shell size 3 (DB, B) and backset spacing within tolerance (0.319" versus 0.318"). The L717DB25PAM4 specifies through-hole right-angle mounting, while the 182-025-113R171 supports panel mount, through-hole, and right-angle configurations. Both are compatible with standard D-Sub 25-position receptacles and mating hardware.

Q: How do the contact finishes differ?

A: The L717DB25PAM4 features gold plating at 8.00µin (0.203µm) thickness, while the 182-025-113R171 specifies flash gold plating. Both provide equivalent electrical conductivity and corrosion resistance for signal transmission. Flash plating is thinner but sufficient for solder termination applications without performance degradation.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The L717DB25PAM4 carries RoHS Compliant status, while the 182-025-113R171 carries ROHS3 Compliant status, which represents an updated compliance standard. Both achieve UL94 V-0 flammability certification. The 182-025-113R171 includes REACH Unaffected designation, providing additional regulatory documentation.

Q: What is the significance of the dielectric material difference?

A: The L717DB25PAM4 uses glass-filled thermoplastic dielectric, while the 182-025-113R171 uses polyamide (PA9T) nylon 9T. Both materials achieve UL94 V-0 flammability rating. Glass-filled thermoplastic typically provides enhanced mechanical rigidity and thermal stability, while polyamide offers good chemical resistance. Material selection should align with specific environmental exposure conditions in the application.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: No. The L717DB25PAM4 operates to 125°C, while the 182-025-113R171 operates to 105°C maximum. For applications requiring sustained operation above 105°C, the L717DB25PAM4 is the required selection. The 182-025-113R171 is suitable only for applications with maximum operating temperature at or below 105°C.

Q: What inventory considerations apply to these parts?

A: The L717DB25PAM4 has 856 units in current stock, while the 182-025-113R171 has 1199 units available. Substitute selection may be driven by inventory availability when primary sourcing is depleted. Both parts maintain active product status with established supply chains.
