TE Connectivity AMP Connectors 4-172211-3 Equivalent & Substitute Parts
Part Overview
The TE Connectivity AMP Connectors 4-172211-3 is a 3-position rectangular connector housing plug designed for applications requiring 0.098" (2.50mm) pitch spacing. This connector operates as a free-hanging, in-line plug housing with crimp contact termination and is constructed from polyamide (PA66) nylon 6/6 material. The part maintains active product status and is RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector specification, enabling component interchangeability in system designs where connector color or inventory availability may vary.

Substitute Part Grouping Explanation
Substitute parts for the 4-172211-3 are identified based on strict equivalence of critical electrical and mechanical parameters. The following parameters must remain constant for substitution validity:
- Connector type (Plug)
- Contact type (Male Pin)
- Number of positions (3)
- Pitch specification (0.098" / 2.50mm)
- Number of rows (1)
- Mounting type (Free Hanging, In-Line)
- Contact termination method (Crimp)
- Insulation material (Polyamide PA66, Nylon 6/6)
- Operating temperature range (-20°C ~ 95°C)
- Series designation (EI)
- RoHS compliance status
- MSL rating (1)
Variations in connector color or inventory levels do not affect functional substitution when all electrical and mechanical parameters remain identical. The base product number 172211 remains consistent across all equivalent parts.

Engineering Selection Recommendations
Both the 4-172211-3 and 172211-3 maintain identical electrical and mechanical specifications within the EI series rectangular connector family. Both parts carry active product status and full RoHS compliance certification. Selection between these parts is determined by application-specific requirements regarding connector housing color and component availability. The substitute part 172211-3 offers significantly higher inventory availability (6852 pieces versus 809 pieces), which may influence procurement decisions for high-volume production requirements. Both parts are suitable for applications operating within the -20°C to 95°C temperature range and maintain unlimited moisture sensitivity classification.
Frequently Asked Questions (FAQ)
Q: Can 172211-3 be used as a direct replacement for 4-172211-3?
A: Yes. Both parts are functionally equivalent rectangular connector plug housings with identical electrical and mechanical specifications. The primary difference is connector housing color (Natural versus Blue) and current inventory levels.
Q: What determines whether a part can substitute for the 4-172211-3?
A: Substitution validity requires equivalence across all critical parameters: 3-position configuration, 0.098" (2.50mm) pitch, male pin contact type, crimp termination, polyamide PA66 insulation material, free-hanging in-line mounting, and -20°C to 95°C operating temperature range. All parts must maintain EI series designation and RoHS compliance status.
Q: Are contacts included with these connector housings?
A: No. Both the main part and substitute are connector housings only. Contacts are not included and must be sourced separately.
Q: Does connector color affect electrical performance?
A: No. Connector color is a cosmetic specification that does not impact electrical or mechanical performance. Both blue and natural color variants maintain identical functional characteristics.
Q: What is the significance of the MSL rating of 1?
A: MSL (Moisture Sensitivity Level) rating of 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling.
Q: Are both parts RoHS compliant?
A: Yes. Both 4-172211-3 and 172211-3 are RoHS compliant and suitable for applications requiring regulatory compliance with RoHS directives.
