Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 171-025-112-021 are classified based on the following critical parameters that determine functional interchangeability:

Primary Matching 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: Solder
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Factors:

• Mounting Type: Panel Mount or Through Hole configurations
• Shell Material: Steel construction
• Contact Type: Signal
• RoHS Compliance Status

Parts are grouped into two categories: Direct Manufacturer Equivalents (same manufacturer, identical specifications) and Similar Cross-Manufacturer Substitutes (alternative manufacturers with compatible electrical and mechanical parameters).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute): The NorComp Inc. 171-025-113R021 is the direct equivalent to the 171-025-112-021. Both parts share identical electrical specifications, mechanical configuration, and compliance certifications. The 171-025-113R021 offers higher inventory availability (2395 units) and is packaged in trays for improved handling. Both parts are ROHS3 compliant and maintain the same operating temperature range and current rating.

Cross-Manufacturer Alternatives: HARTING parts (09653616711, 09653616712, 09653617711, 09663216701, 09663216702, 09663217701, 09663217702) provide functional substitution with enhanced electrical performance. These parts support higher current ratings (6.5A to 7.5A versus 5A) and extended operating temperature ranges (-55°C to 125°C versus -50°C to 100°C). HARTING substitutes are ROHS3 compliant and maintain UL94 V-0 flammability ratings. Mounting configuration differs; HARTING parts are through-hole only, without panel mount features.

Panel Mount Equivalent: The Hirose Electric Co Ltd SDBB-25P(55) maintains panel mount and through-hole configuration matching the original part. This connector features gold-plated contacts and nickel-plated steel shell. Current rating is lower at 3A, and voltage rating is specified at 350V. This part is suitable for applications with lower current requirements and is RoHS compliant.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 171-025-112-021 with the 171-025-113R021? A: Yes. The 171-025-113R021 is a direct equivalent with identical electrical and mechanical specifications. Both are NorComp 171 series connectors with 25 positions, solder termination, and ROHS3 compliance. The primary difference is packaging format (tray versus standard).

Q: What are the key differences between NorComp and HARTING substitutes? A: NorComp parts maintain panel mount capability with 5A current rating and -50°C to 100°C operating range. HARTING substitutes offer higher current ratings (6.5A to 7.5A) and wider operating temperature range (-55°C to 125°C) but are through-hole only without panel mount features. Both manufacturers provide UL94 V-0 rated connectors with ROHS3 compliance.

Q: Is the Hirose SDBB-25P(55) a suitable replacement? A: The Hirose part maintains panel mount configuration and 25-position D-Sub format. However, the current rating is reduced to 3A compared to the original 5A specification. This part is suitable only for applications with lower current requirements.

Q: What mounting differences exist between substitute options? A: The original 171-025-112-021 and NorComp 171-025-113R021 support both panel mount and through-hole mounting. HARTING substitutes are through-hole only. The Hirose SDBB-25P(55) supports both panel mount and through-hole configurations.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are RoHS compliant. NorComp and HARTING parts are ROHS3 compliant. The Hirose part is RoHS compliant.

Q: What is the difference between stamped and machined contact forms? A: The original part uses stamped contacts (Brass material). HARTING substitutes with higher current ratings (7.5A) use machined contacts (Copper Alloy material) for improved durability and performance. Stamped contacts are suitable for standard applications; machined contacts provide enhanced reliability in high-cycle applications.
