Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 172-025-282-021 are qualified based on the following critical parameters that must align with the main part:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• Contact Finish: Gold

Substitutes are grouped into two categories:

Direct Equivalent (Same Manufacturer): 172-025-283L021 from NorComp Inc. maintains identical electrical and mechanical specifications with packaging in Tray format.

Cross-Manufacturer Equivalents: Parts from TE Connectivity AMP Connectors (205738-1, 5-827017-1) and Amphenol ICC (FCE17B25SN2D0, FCE17B25SN480, FCE17B25SN4D0) meet core functional requirements with variations in shell finish, current rating, operating temperature, and contact material that remain within acceptable engineering tolerances for D-Sub 25 position receptacle applications.

Parameter Comparison

Engineering Selection Recommendations

172-025-283L021 (NorComp Inc.): This is the primary direct equivalent. It maintains identical specifications to the main part with ROHS3 compliance and identical operating temperature range. Selection is appropriate when packaging in Tray format is acceptable and NorComp supply chain continuity is preferred.

205738-1 (TE Connectivity AMP Connectors): This part meets core D-Sub 25 position receptacle requirements with UL94 V-0 flammability rating and gold contact finish. The higher current rating (6A vs. 5A) and extended lower temperature limit (-55°C vs. -50°C) provide additional margin. However, the upper operating temperature is limited to 105°C compared to 125°C on the main part. RoHS status is not applicable. Selection is appropriate for applications where the reduced upper temperature limit does not conflict with design requirements.

5-827017-1 (TE Connectivity AMP Connectors): Limited specification data is provided for this part. Selection requires confirmation of full electrical and mechanical compatibility with the main part specifications.

FCE17B25SN2D0, FCE17B25SN480, FCE17B25SN4D0 (Amphenol ICC): These three variants from the FCE17 series are functionally equivalent with RoHS compliance and gold contact finish. All three have identical electrical and mechanical specifications with differences only in flange feature configuration (Housing/Shell Unthreaded vs. Board Side 4-40). Operating temperature range is limited to -40°C ~ 85°C. Selection depends on specific mounting requirements and whether the reduced temperature range is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can 172-025-283L021 be used as a direct replacement for 172-025-282-021?

A: Yes. Both parts are manufactured by NorComp Inc., share identical connector specifications (25 position, 2 row, DB shell size, female sockets, solder termination), and maintain the same operating temperature range (-50°C ~ 125°C) and ROHS3 compliance. The only difference is packaging format (Tray vs. standard packaging).

Q: What are the key differences between NorComp and TE Connectivity AMP substitutes?

A: The 205738-1 from TE Connectivity offers a higher current rating (6A vs. 5A) and lower minimum operating temperature (-55°C vs. -50°C), but has a reduced maximum operating temperature (105°C vs. 125°C). Shell finish differs (Yellow Chromate Plated Zinc vs. Nickel Plated), and contact material is Phosphor Bronze instead of Brass. RoHS status is not applicable for this part.

Q: Are the Amphenol ICC FCE17 series parts suitable replacements?

A: The FCE17B25SN2D0, FCE17B25SN480, and FCE17B25SN4D0 are functionally compatible for 25 position D-Sub receptacle applications with RoHS compliance and gold contact finish. However, the operating temperature range is restricted to -40°C ~ 85°C, which is narrower than the main part. Selection requires confirmation that this temperature range meets application requirements. The three variants differ only in flange feature configuration.

Q: What mounting differences exist between substitute parts?

A: The main part and 172-025-283L021 specify Panel Mount with Through Hole and Board Side (4-40) flange. The 205738-1 uses Through Hole mounting with Housing/Shell (Unthreaded) flange. The FCE17 series variants offer two flange options: FCE17B25SN2D0 has Housing/Shell (Unthreaded), while FCE17B25SN480 and FCE17B25SN4D0 have Board Side (4-40). Mounting configuration must align with PCB design requirements.

Q: How do shell finish specifications affect part selection?

A: The main part uses Steel with Nickel Plating. Substitutes vary: 172-025-283L021 matches this specification, 205738-1 uses Yellow Chromate Plated Zinc, and FCE17 series use Tin Plating. Shell finish affects corrosion resistance and environmental durability. Selection should consider the operating environment and any specific finish requirements in the design specification.

Q: Are there temperature limitations when using substitute parts?

A: Yes. The main part operates from -50°C to 125°C. The 205738-1 operates from -55°C to 105°C (lower minimum, higher maximum limit of 105°C). The FCE17 series operates from -40°C to 85°C (higher minimum, lower maximum). Applications requiring the full -50°C to 125°C range must use the main part or 172-025-283L021.

Q: What is the significance of contact material differences?

A: The main part uses Brass contacts, while most substitutes use Phosphor Bronze. Both materials are standard for D-Sub connectors and provide reliable signal transmission. Phosphor Bronze offers slightly different mechanical and electrical properties but is functionally equivalent for standard D-Sub applications. Contact finish (Gold) is consistent across all parts.
