TE Connectivity AMP Connectors 144473-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 144473-3 is a 2-position rectangular connector receptacle housing with 5.00mm pitch, designed for free-hanging in-line mounting applications. This component belongs to the Junior Power Timer series and is classified as an active product. The receptacle housing accommodates female socket contacts via crimp termination and operates across a temperature range of -40°C to 100°C. Substitute parts are necessary when specific color requirements, material specifications, or inventory availability necessitate alternative housing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector receptacle housings 144473-3 is determined by strict adherence to the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (2), pitch (5.00mm), number of rows (1), mounting type (free hanging in-line), and contact termination method (crimp). All substitute parts listed maintain these core electrical and mechanical specifications. Variations in housing color, insulation material composition, and operating temperature range do not affect functional interchangeability within the connector system. RoHS compliance status and moisture sensitivity level remain consistent across all substitutes. Series designation and packaging format represent secondary differentiators that do not impact electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS compliance, ensuring regulatory conformity for current applications. The 144473-3 operates within -40°C to 100°C, while substitute part 928343-2 extends the upper temperature limit to 110°C, providing additional thermal margin for elevated-temperature environments. Substitute part 4-963210-1 utilizes polybutylene terephthalate (PBT) glass-filled insulation material, differing from the polyamide (PA66) nylon 6/6 composition of the primary part. Parts 826008-1 and 827551-3 employ glass-filled polyamide variants, offering enhanced mechanical properties compared to unfilled polyamide. Selection between substitutes should prioritize application-specific requirements regarding insulation material performance, operating temperature demands, and color coding standards. All parts maintain identical electrical and mechanical interface specifications, ensuring direct functional interchangeability within the connector system.

Frequently Asked Questions (FAQ)

Q: Can substitute parts be used interchangeably with the 144473-3 in existing assemblies?

A: Yes. All substitute parts maintain identical connector type (receptacle), contact type (female socket), position count (2), pitch (5.00mm), row configuration (1), mounting type (free hanging in-line), and crimp termination specifications. Electrical and mechanical compatibility is preserved across all listed substitutes.

Q: What are the primary differences between the substitute parts?

A: Differences exist in housing color, insulation material composition, and operating temperature range. The 144473-3 features red polyamide (PA66) nylon 6/6 housing with -40°C to 100°C operation. Substitute 4-963210-1 uses brown polybutylene terephthalate (PBT) glass-filled material. Substitute 826008-1 provides gray polyamide (PA66) nylon 6/6. Substitute 827551-3 offers black polyamide (PA66) nylon 6/6 glass-filled material. Substitute 928343-2 provides natural polyamide (PA66) nylon 6/6 with extended -40°C to 110°C temperature range.

Q: Does insulation material variation affect connector performance?

A: Insulation material differences do not affect electrical performance or mechanical fit. Material selection impacts mechanical durability, chemical resistance, and thermal stability. Glass-filled variants (4-963210-1, 827551-3) provide enhanced mechanical properties. Selection should align with application environmental conditions and material compatibility requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS compliance status. The 144473-3 is RoHS Compliant, while 4-963210-1 is ROHS3 Compliant. Parts 826008-1, 827551-3, and 928343-2 are RoHS Compliant. All parts satisfy current regulatory requirements.

Q: What is the significance of the operating temperature range differences?

A: The 144473-3 operates from -40°C to 100°C. Substitute 928343-2 extends the upper limit to 110°C, providing 10°C additional thermal margin. This difference is relevant only for applications requiring operation near or above 100°C. For standard applications within -40°C to 100°C, all parts perform identically.

Q: How does packaging format affect part selection?

A: Packaging format (bulk versus standard) does not affect electrical or mechanical specifications. Packaging selection depends on procurement volume requirements and inventory management practices. The 144473-3 packaging format is not specified, while 4-963210-1, 827551-3, and 928343-2 are supplied in bulk packaging.

Q: Are contacts included with these connector housings?

A: No. All listed parts are connector housings only. Contacts are not included and must be procured separately. The note "Contacts Not Included" applies to all parts in this substitution group.
