Substitute Part Grouping Explanation

The 172-E25-113R021 is identified as a substitute part within the NorComp 172-E series family. Substitution between these connectors is based on the following allowed parameters:

• Manufacturer consistency: Both parts are manufactured by NorComp Inc.
• Product family alignment: Both belong to the 172-E series
• Connector category: Both are D-Sub, D-Shaped connectors
• Connector type: Both feature plug configuration with male pins
• Mounting configuration: Both are panel mount, through hole designs
• Termination method: Both use solder termination
• Shell and contact materials: Both feature nickel-plated steel shells with gold-plated contacts
• Environmental compliance: Both meet UL94 V-0 flammability rating and ROHS3 compliance

The primary difference is the number of positions: the main part provides 37 positions, while the substitute provides 25 positions. This substitution is applicable only when circuit design modifications permit the use of a 25-position connector.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 172-E37-101-021 and 172-E25-113R021 must be based on circuit pin count requirements. The 37-position connector accommodates applications requiring 37 signal connections, while the 25-position variant is suitable for designs requiring 25 or fewer connections. Both parts meet ROHS3 compliance and UL94 V-0 flammability standards, ensuring regulatory alignment for industrial and commercial applications. The 172-E25-113R021 offers higher inventory availability at 1216 units. Selection should prioritize the connector that matches the exact pin count specification of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 172-E25-113R021 be used as a direct replacement for the 172-E37-101-021?

A: No. The 172-E25-113R021 provides 25 positions compared to the 37 positions of the main part. Direct substitution is only possible if the application circuit design can operate with 25 connections instead of 37.

Q: Are both connectors compatible with the same mating receptacles?

A: No. D-Sub connectors are position-specific. A 37-position plug requires a 37-position receptacle, and a 25-position plug requires a 25-position receptacle. Mating compatibility is determined by position count and shell size.

Q: What is the difference in packaging between these parts?

A: The 172-E37-101-021 packaging is not specified in the available data. The 172-E25-113R021 is supplied in Tray packaging.

Q: Do both connectors meet the same environmental and compliance standards?

A: The 172-E25-113R021 is specified as ROHS3 compliant with UL94 V-0 flammability rating and operates across -50°C to 100°C. Equivalent specifications for the 172-E37-101-021 are not provided in the available data.

Q: Which part should be selected for new designs?

A: Selection must be based on the required number of signal connections. If 25 connections are sufficient, the 172-E25-113R021 offers higher inventory availability. If 37 connections are required, the 172-E37-101-021 is the appropriate choice.
