Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-1971773-4 are identified based on strict equivalence of the following critical parameters:

• Connector Type: Plug housing configuration
• Number of Positions: 4-position layout
• Pitch Specification: 0.236" (6.00mm) contact spacing
• Contact Type: Female blade socket contacts
• Contact Termination: Crimp attachment method
• Mounting Configuration: Free hanging in-line orientation
• Operating Temperature Range: -55°C ~ 105°C
• Fastening Type: Latch holder mechanism
• RoHS Compliance: RoHS compliant status
• Moisture Sensitivity Level: MSL 1 (unlimited)

Substitute parts may differ in insulation material composition and color designation while maintaining full electrical and mechanical compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-1971773-4 and 5-1971773-4 are active production parts manufactured by TE Connectivity AMP Connectors with full RoHS compliance and MSL 1 moisture sensitivity ratings. Selection between these parts is determined by application-specific requirements:

2-1971773-4 (Purple, PBT Glass Filled): Select this part when the original design specification requires polybutylene terephthalate insulation material with glass reinforcement and purple housing color identification.

5-1971773-4 (Gray, Polyamide Nylon): Select this substitute when polyamide nylon insulation material is acceptable and gray housing color is compatible with system requirements. This part offers significantly higher inventory availability (8022 pieces versus 867 pieces).

Both parts maintain identical electrical performance, mechanical compatibility, and thermal operating range across the specified -55°C to 105°C temperature envelope. The choice between materials and colors does not affect connector functionality, mating characteristics, or contact performance.

Frequently Asked Questions (FAQ)

Q: Can the 5-1971773-4 directly replace the 2-1971773-4 in existing applications?

A: Yes. Both parts maintain identical connector type, position count, pitch specification, contact configuration, termination method, and operating temperature range. The substitute part is mechanically and electrically compatible for direct replacement.

Q: What is the difference between the insulation materials used in these parts?

A: The 2-1971773-4 uses polybutylene terephthalate (PBT) with glass reinforcement, while the 5-1971773-4 uses polyamide (PA) nylon. Both materials are suitable for the -55°C to 105°C operating temperature range and maintain equivalent mechanical properties for this connector application.

Q: Does the color difference affect connector performance?

A: No. Color designation (purple versus gray) is a visual identification feature only and does not impact electrical performance, mechanical fit, or contact reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2-1971773-4 and 5-1971773-4 are RoHS compliant with MSL 1 moisture sensitivity level ratings.

Q: What is the significance of the series designation difference?

A: The 2-1971773-4 belongs to the Power Triple Lock Standard series, while the 5-1971773-4 belongs to the Power Triple Lock High Temp series. Both series maintain the same operating temperature range and are functionally equivalent for this connector housing specification.

Q: Are contacts included with these connector housings?

A: No. Both parts are connector housings only. Contacts are not included and must be ordered separately.

Q: Which part should be selected for new designs?

A: Selection is based on material and color requirements specific to the application. Both parts are active production items with full compliance certifications. The 5-1971773-4 offers higher inventory availability if supply chain considerations are a factor.
