TE Connectivity 1379029-3 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1379029-3 is a 4-position receptacle housing connector from the Micro Quadlok series, designed for 0.100" (2.54mm) pitch applications. This connector features a blue polybutylene terephthalate (PBT) glass-filled housing with female socket contacts, latch lock fastening, and crimp termination. The part is actively manufactured and maintains full ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, allowing for functional interchangeability in applications where housing color does not impose design constraints.

Substitute Part Grouping Explanation

Substitute parts for the 1379029-3 are identified within the Micro Quadlok series based on electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Substitution-Determining Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 4
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled
• Operating Temperature Range: -40°C to 85°C
• Series: Micro Quadlok

Non-Substitution-Determining Parameters:

• Housing Color: Blue (1379029-3), Black (1379029-1), Brown (1379029-6)

All three parts maintain identical electrical and mechanical specifications. Housing color variation does not affect connector functionality, mating capability, or performance characteristics. Substitution is valid when color selection is not a design requirement.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1379029-3, 1379029-1, and 1379029-6—are active products manufactured by TE Connectivity and maintain full ROHS3 compliance. Selection between these parts is determined by application-specific color requirements.

1379029-3 (Blue Housing): Select when blue color coding is required for circuit identification, wiring harness organization, or design specification. Current inventory: 1,164 pieces.

1379029-1 (Black Housing): Select when black color coding is required or when color specification is not constrained. This part maintains the highest inventory availability at 13,500 pieces, supporting high-volume production requirements.

1379029-6 (Brown Housing): Select when brown color coding is required for specific application standards or design protocols. Current inventory: 3,564 pieces.

All parts support identical electrical performance, mating cycles, and environmental operating ranges. Substitution between any of these three parts is valid from an electrical and mechanical standpoint when housing color does not impose design constraints.

Frequently Asked Questions (FAQ)

Q: Can 1379029-1 (black) be used in place of 1379029-3 (blue)?

A: Yes. Both parts are electrically and mechanically equivalent 4-position receptacle connectors with identical pitch, contact type, termination method, and operating temperature range. Substitution is valid when housing color is not a design requirement.

Q: What is the primary difference between these three connector housings?

A: The only difference is housing color: blue (1379029-3), black (1379029-1), and brown (1379029-6). All other electrical, mechanical, and environmental specifications are identical.

Q: Are contacts included with these connector housings?

A: No. All three parts are housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). The 1379029-3 and 1379029-1 have confirmed REACH Unaffected status. The 1379029-6 REACH status is listed as Vendor Undefined.

Q: Which part should be selected for maximum inventory availability?

A: The 1379029-1 (black housing) offers the highest inventory level at 13,500 pieces, supporting immediate fulfillment of large-volume orders.

Q: Are these connectors suitable for high-temperature applications?

A: These connectors operate within the -40°C to 85°C temperature range. Applications requiring operation outside this range require alternative connector selection.

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

A: The pitch is 0.100" (2.54mm), which defines the center-to-center spacing between connector positions. This specification must match the mating connector and PCB layout to ensure proper alignment and electrical connection.
