Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-2178029-3 rectangular connector receptacle housing are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are established through the following key parameters:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Blade Socket
• Number of Positions: 3
• Pitch: 0.197" (5.00mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Operating Temperature Range: -40°C ~ 105°C
• Color: Natural

Parts meeting all these parameters are classified as direct parametric equivalents and are suitable for substitution in applications where the 1-2178029-3 is specified. Compliance certifications including RoHS status and MSL rating remain consistent across equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 1-2178029-3 and the substitute part 2178029-3 are active products from TE Connectivity AMP Connectors with identical electrical and mechanical specifications. Both parts maintain RoHS compliance and MSL rating of 1 (Unlimited), confirming suitability for equivalent applications.

The substitute part 2178029-3 demonstrates higher inventory availability (13,746 pieces in stock compared to 800 pieces for the main part), making it a viable alternative for procurement and supply chain planning. The parametric equivalence across all critical connector specifications—including pitch, contact configuration, termination method, and operating temperature range—establishes functional interchangeability.

Selection between these parts should be based on procurement requirements, inventory availability, and lead time considerations. Both parts are suitable for applications requiring a 3-position, 5.00mm pitch rectangular connector receptacle housing with crimp termination and latch lock fastening.

Frequently Asked Questions (FAQ)

Q: Are the 1-2178029-3 and 2178029-3 parts fully interchangeable?

A: Yes. Both parts are parametric equivalents meeting identical specifications for connector type, contact configuration, pitch, mounting method, termination type, and operating temperature range. They are suitable for direct substitution in applications where either part number is specified.

Q: What is the significance of the different part numbers?

A: The part numbers 1-2178029-3 and 2178029-3 represent different catalog designations from TE Connectivity AMP Connectors for the same rectangular connector receptacle housing. Both reference the base product number 2178029 with 3-position configuration.

Q: Does the substitute part maintain the same compliance certifications?

A: Yes. Both parts carry identical RoHS compliance status and MSL rating of 1 (Unlimited), confirming equivalent environmental and regulatory compliance.

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: What mounting configuration do these connectors support?

A: Both parts are configured for free-hanging in-line mounting, suitable for applications requiring flexible positioning without fixed panel mounting.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.197" (5.00mm), representing the center-to-center distance between contact positions. This specification is critical for mechanical compatibility with mating connectors and contact alignment.

Q: What termination method is used for these connector housings?

A: Both parts utilize crimp termination, requiring crimped contacts for wire attachment. This method provides secure electrical connection and is standard for this connector category.

Q: What insulation material is used in these housings?

A: Both parts use Polyamide (PA66), Nylon 6/6 insulation material, providing thermal stability and mechanical durability across the operating temperature range of -40°C to 105°C.
