Part Overview

The TE Connectivity 1776139-6 is a 6-position terminal block header with male pins, shrouded on 2 sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. The part operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C. Equivalent alternatives are available from active product lines that maintain electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1776139-6 is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

Number of positions: 6
Pitch: 0.200" (5.08mm) or 0.197" (5.00mm) with mechanical compatibility verification
Header orientation: Vertical
Termination style: Solder
Mounting type: Through hole
Current rating (UL): 15 A minimum
Voltage rating (UL): 300 V minimum
Material flammability rating: UL94 V-0
Contact mating finish: Tin

Secondary Compatibility Factors:

Shrouding configuration (2-side or 4-side acceptable based on application space constraints)
Contact tail length and insulation height (mechanical fit in PCB)
Operating temperature range (must encompass or exceed -40°C to 110°C)
Housing material (polyamide or polybutylene terephthalate acceptable)
Contact material (copper alloy or brass acceptable)

Substitute parts are grouped by pitch specification (5.08mm exact match or 5.00mm near-equivalent) and shrouding configuration. Parts with 4-side shrouding provide enhanced EMI shielding but require verification of PCB layout clearance. All listed substitutes maintain UL94 V-0 flammability compliance and tin contact finish.

Engineering Selection Recommendations

Exact Pitch Match (5.08mm) - Preferred for Direct Substitution:

The Molex Eurostyle ESE 39531 series parts (0395310006, 0395311006, 0395314006) provide exact 0.200" (5.08mm) pitch matching with the original TE Connectivity 1776139-6. These parts are active products with ROHS3 compliance and maintain all critical electrical parameters. Selection between 2-side and 4-side shrouding variants depends on PCB layout constraints and EMI requirements.

0395310006 (Molex): 2-side shrouding, exact pitch match, active status, ROHS3 compliant. Operating temperature -40°C to 105°C meets original specification minimum.
0395311006 (Molex): 4-side shrouding, exact pitch match, active status, ROHS3 compliant. Provides enhanced shielding with same electrical ratings.
0395314006 (Molex): 4-side shrouding, exact pitch match, active status, ROHS3 compliant, extended operating temperature to 140°C. Suitable for high-temperature applications.

Near-Pitch Match (5.00mm) - Secondary Option:

Amphenol PCD ELFH series (ELFH06160, ELFH06180) and Phoenix Contact 1753518 operate at 0.197" (5.00mm) pitch, representing a 0.08mm deviation from the original specification. These parts are active products with RoHS compliance. Mechanical compatibility requires verification of PCB pad spacing and connector mating interface.

ELFH06160 (Amphenol): 2-side shrouding, 5.00mm pitch, RoHS compliant, active status.
ELFH06180 (Amphenol): 4-side shrouding, 5.00mm pitch, RoHS compliant, active status.
1753518 (Phoenix Contact): 2-side shrouding, 5.00mm pitch, ROHS3 compliant, active status. Current rating 12 A (UL) is below original 15 A specification.

Compliance and Availability:

All recommended substitutes maintain UL94 V-0 flammability rating, tin contact finish, and 300 V (UL) voltage rating. Molex parts offer highest inventory availability (939 to 14,953 units) and exact pitch matching. Amphenol and Phoenix Contact parts provide alternative sourcing with active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395310006 directly replace the TE Connectivity 1776139-6?

A: Yes. The Molex 0395310006 matches all critical parameters: 6 positions, 0.200" (5.08mm) pitch, vertical orientation, 2-side shrouding, solder termination, 15 A (UL) current rating, 300 V (UL) voltage rating, UL94 V-0 flammability, and tin contact finish. Operating temperature range (-40°C to 105°C) encompasses the original specification minimum. This part is active and ROHS3 compliant.

Q: What is the difference between 2-side and 4-side shrouding?

A: Shrouding configuration refers to the number of sides of the connector housing that are enclosed. 2-side shrouding provides lateral protection and is suitable for standard applications. 4-side shrouding provides enhanced EMI shielding and mechanical protection on all sides. Selection depends on PCB layout clearance and electromagnetic interference requirements. Both configurations maintain identical electrical ratings.

Q: Why is the Phoenix Contact 1753518 listed as a secondary option?

A: The Phoenix Contact 1753518 operates at 0.197" (5.00mm) pitch rather than the original 0.200" (5.08mm), requiring mechanical compatibility verification. Additionally, the current rating is 12 A (UL), which is below the original 15 A specification. This part is suitable only when the lower current rating is acceptable and PCB pad spacing accommodates the 5.00mm pitch.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS or ROHS3 compliance certification. The original TE Connectivity 1776139-6 lists RoHS status as "Not applicable" due to its obsolete classification. Active substitute parts meet current RoHS requirements.

Q: Can I use a 4-side shrouded part in place of a 2-side shrouded part?

A: Mechanical compatibility must be verified. 4-side shrouding increases the overall connector envelope, potentially requiring additional PCB clearance. Electrical performance is identical between 2-side and 4-side variants. Verify PCB layout and mating connector interface before substitution.

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

A: The original TE Connectivity 1776139-6 operates from -40°C to 110°C. Most Molex substitutes operate to 105°C, which is acceptable for applications not exceeding 105°C. The Molex 0395314006 extends to 140°C, providing margin for high-temperature applications. Verify application temperature requirements before selection.

Q: Are there inventory considerations for these substitute parts?

A: Yes. Molex parts offer substantial inventory availability (939 to 14,953 units in stock). Amphenol ELFH series parts range from 697 to 874 units. Phoenix Contact 1753518 has 1,230 units available. Verify current inventory status with suppliers for procurement planning.

Q: What is the contact material difference between copper alloy and brass?

A: The original TE Connectivity 1776139-6 uses copper alloy contacts. Most Molex and Amphenol substitutes use brass contacts. Both materials provide equivalent electrical conductivity and tin plating compatibility. This difference does not affect electrical performance or compatibility.

Q: Can I mix 5.08mm and 5.00mm pitch connectors in the same application?

A: No. Pitch specifications determine PCB pad spacing and connector mating interface geometry. Mixing different pitches will result in misalignment and connection failure. Select parts with matching pitch specifications for the same application.
