• Flammability rating: UL94 V-0
• Compliance: ROHS3 Compliant

Acceptable Variations:

• Mounting type: Panel mount or through hole configurations
• Flange feature: Board side, housing/shell, or unthreaded variations
• Contact form: Stamped or machined
• Dielectric material: Polyamide (PA9T, PA6T) or Polybutylene Terephthalate (PBT)
• Current rating: 3A to 7.5A
• Operating temperature: -50°C to -55°C minimum; 100°C to 125°C maximum
• Packaging: Tray or bulk

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (NorComp Series 171): 171-025-113R911 and 172-E25-113R911 are direct functional equivalents to 171-025-112-911. All three parts share identical electrical and mechanical specifications including 25 positions, panel mount configuration, 5A current rating, and -50°C to 100°C operating range. All are ROHS3 compliant. Selection between these NorComp parts depends on packaging requirements (tray vs. bulk) and dielectric material preference (Polyamide PA9T vs. PA6T).

HARTING Series Substitutes (09653616711, 09653616712, 09653617711, 09663216701, 09663216702, 09663217701, 09663217702): HARTING D-Sub plugs are functionally compatible substitutes with enhanced specifications. These parts maintain the 25-position, 2-row configuration and solder termination. Key differences include through-hole mounting (without panel mount flange), higher current ratings (6.5A to 7.5A), and extended operating temperature range (-55°C to 125°C). All HARTING parts are ROHS3 compliant. Selection among HARTING variants depends on flange feature requirements (M3 vs. 4-40 thread) and contact form preference (stamped vs. machined).

Hirose SDBB-25P(55) Substitute: The Hirose SDBB-25P(55) is a compatible substitute with panel mount configuration matching the original part. This connector maintains 25 positions, solder termination, and nickel-plated steel shell. The current rating is lower at 3A, and operating temperature range is -50°C to 100°C. This part is RoHS compliant. Selection of this part is appropriate for applications with lower current requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute a HARTING connector for the NorComp 171-025-112-911? A: Yes. HARTING D-Sub plugs 09653616711, 09653616712, 09653617711, 09663216701, 09663216702, 09663217701, and 09663217702 are functionally compatible. All maintain 25 positions, 2-row configuration, solder termination, and UL94 V-0 flammability rating. Verify mounting configuration compatibility in your application, as HARTING parts feature through-hole mounting without panel mount flange.

Q: What is the difference between 171-025-113R911 and 172-E25-113R911? A: Both are NorComp 25-position D-Sub plugs with identical electrical and mechanical specifications. The primary differences are dielectric material (PA9T vs. PA6T), contact form (stamped vs. machined), and shell color (black vs. white). Both are ROHS3 compliant and suitable for the same applications.

Q: Can I use the Hirose SDBB-25P(55) as a direct replacement? A: The Hirose SDBB-25P(55) is compatible for applications with current requirements of 3A or less. It maintains panel mount configuration and 25-position layout. The lower current rating and different contact material (phosphor bronze vs. brass) should be evaluated against your application requirements.

Q: Are all substitute parts ROHS3 compliant? A: All NorComp and HARTING substitutes listed are ROHS3 compliant. The Hirose SDBB-25P(55) is RoHS compliant. Verify compliance requirements for your specific application.

Q: What packaging options are available? A: NorComp 171-025-113R911 and 172-E25-113R911 are supplied in tray packaging. HARTING parts 09653616711, 09653617711, 09663216701, 09663216702, 09663217701, and 09663217702 are supplied in bulk packaging. HARTING 09653616712 and Hirose SDBB-25P(55) are supplied in tray packaging. Confirm packaging requirements with your procurement process.

Q: What is the difference between M3 and 4-40 flange features on HARTING connectors? A: The flange feature indicates the mounting hole thread specification. M3 refers to metric M3 threads, while 4-40 refers to UNC (Unified National Coarse) threads. Select based on your panel mounting hardware specifications.
