Key Parameters

Substitute Part Grouping Explanation

The identified substitute part 182-025-113R171 (NorComp Inc.) qualifies as an equivalent alternative based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Connector Style: D-Sub
• Connector Type: Plug, Male Pins
• Number of Positions: 25
• Number of Rows: 2
• Shell Size: 3 (DB, B)
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Termination: Solder
• Contact Type: Signal
• Contact Material: Brass
• Color: Black
• Material Flammability Rating: UL94 V-0
• Backset Spacing: 0.318–0.319" (functionally equivalent)

Variant Parameters (Allowed Substitution Variance):

• Shell Material Finish: Tin Plated (L717DFB25PAM4RM6) vs. Nickel Plated (182-025-113R171)
• Contact Finish Thickness: 20.0µin (L717DFB25PAM4RM6) vs. Flash (182-025-113R171)
• Current Rating: 7.5A (L717DFB25PAM4RM6) vs. 5A (182-025-113R171)
• Operating Temperature: -55°C to 155°C (L717DFB25PAM4RM6) vs. -55°C to 105°C (182-025-113R171)
• Flange Feature: Housing/Shell Unthreaded (L717DFB25PAM4RM6) vs. 4-40 (182-025-113R171)

Parameter Comparison

Engineering Selection Recommendations

Primary Part: L717DFB25PAM4RM6 (Amphenol ICC)

• Active product status with established manufacturing and supply chain
• Supports higher current capacity (7.5A) and broader operating temperature range (-55°C to 155°C)
• RoHS compliant with defined voltage rating (300V)
• Heavier gold contact finish (20.0µin) provides enhanced durability
• Unthreaded shell housing

Substitute Part: 182-025-113R171 (NorComp Inc.)

• Active product status, ROHS3 compliant
• Lower current rating (5A) restricts use to applications with reduced power requirements
• Narrower operating temperature ceiling (105°C maximum) limits use in high-temperature environments
• Flange feature with 4-40 threaded capability provides additional mechanical fastening options
• Flash gold contact finish suitable for standard-duty applications

Selection between these parts depends on specific application requirements for current capacity, temperature operating range, and mechanical fastening configuration. Both meet core D-Sub 25-position connector specifications.

Frequently Asked Questions (FAQ)

Q: What makes 182-025-113R171 a suitable substitute for L717DFB25PAM4RM6? A: Both connectors share identical core specifications: 25-position D-Sub plug configuration with male pins, 2-row layout at shell size 3 (DB, B), panel mount through-hole right-angle solder termination, brass contacts, and UL94 V-0 flammability rating. These parameters define mechanical and electrical interchangeability for standard D-Sub applications.

Q: What are the key differences in operational capability? A: The primary differences are current rating (7.5A vs. 5A), operating temperature range (-55°C to 155°C vs. -55°C to 105°C), and contact finish thickness (20.0µin vs. Flash). Applications requiring sustained current above 5A or operating temperatures exceeding 105°C must use the L717DFB25PAM4RM6.

Q: Does the nickel-plated shell of 182-025-113R171 affect compatibility? A: Shell finish does not affect electrical or mechanical mating compatibility. Nickel plating provides corrosion resistance equivalent to tin plating in most industrial environments. Material selection depends on specific environmental exposure and cost considerations.

Q: Are the backset spacing differences significant? A: The 0.001" (0.02mm) spacing difference between connectors (0.319" vs. 0.318") is within standard manufacturing tolerance and does not affect PCB or panel mount compatibility.

Q: Which part should be selected for high-temperature applications? A: Applications with operating temperatures above 105°C require the L717DFB25PAM4RM6, which supports up to 155°C. The 182-025-113R171 is limited to 105°C maximum.

Q: Can 182-025-113R171 be used in existing designs specified for L717DFB25PAM4RM6? A: Substitution is permissible only when application current requirements do not exceed 5A and operating temperatures remain below 105°C. Verification against specific design specifications is necessary before substitution.
