Molex 0050361809 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0050361809 is a shrouded vertical header connector from the Mini-Fit Jr 5566 series, designed for board-to-cable/wire applications with 3 positions at 0.165" (4.20mm) pitch. This connector features through-hole solder termination, locking ramp fastening, and tin-plated brass contacts. The part is currently obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Type: Header with Male Pin contacts
• Position Count & Pitch: 3 positions at 0.165" (4.20mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Shrouding & Fastening: Shrouded 4-wall design with locking ramp
• Contact Material & Finish: Brass with tin plating
• Insulation Material: Polyamide/Nylon composition
• Flammability & Compliance: UL94 V-0 rating, ROHS3 compliant

Substitute parts are grouped into two categories: direct Molex Mini-Fit Jr series equivalents (0469990563, 0039305038, 1726470103) and cross-manufacturer alternatives from TE Connectivity VAL-U-LOK series (2029056-3, 2029113-3, 2029167-3). All listed substitutes maintain functional compatibility across the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Molex Mini-Fit Jr Series Substitutes (0469990563, 0039305038, 1726470103)

These parts maintain direct compatibility within the Molex Mini-Fit Jr family. Parts 0469990563 and 0039305038 are active equivalents with identical electrical and mechanical specifications to the obsolete 0050361809, differing only in packaging format (bulk vs. tray) and insulation color. Part 1726470103 from the Mini-Fit Jr 172647 series offers the highest inventory availability (17,635 units) and includes glow wire compliance certification. The insulation height variance (0.492" vs. 0.490") and UL94 V-2 rating (versus V-0) represent minor deviations suitable for general purpose and industrial applications where V-2 flammability compliance is acceptable.

TE Connectivity VAL-U-LOK Series Substitutes (2029056-3, 2029113-3, 2029167-3)

These cross-manufacturer alternatives provide functional equivalence with specified operating temperature ranges (-40°C ~ 105°C), current ratings (9A), and voltage ratings (600VAC). All three maintain UL94 V-0 flammability compliance and ROHS3 certification. Insulation height is marginally increased (0.504" vs. 0.490"), and contact finish thickness is reduced (80.0µin vs. 100.0µin). Part 2029113-3 features glass-filled nylon insulation with white color, while 2029167-3 offers bulk packaging. These parts are suitable for applications requiring explicit thermal and electrical performance specifications.

Selection Criteria

For direct replacement in existing designs, select 0469990563 or 0039305038 to maintain identical Mini-Fit Jr 5566 series compatibility. For new designs requiring documented operating parameters, select from the TE Connectivity VAL-U-LOK series. Part 1726470103 is recommended for high-volume applications due to superior inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050361809 be directly replaced with 0469990563?

A: Yes. Both parts are Molex Mini-Fit Jr 5566 series headers with identical connector type, position count, pitch, mounting method, shrouding, termination, and contact specifications. The primary difference is product status (obsolete vs. active) and packaging format. Electrical and mechanical compatibility is complete.

Q: What is the difference between Molex and TE Connectivity substitutes?

A: Molex substitutes (0469990563, 0039305038, 1726470103) maintain the Mini-Fit Jr series design with identical or near-identical insulation heights and contact specifications. TE Connectivity VAL-U-LOK substitutes (2029056-3, 2029113-3, 2029167-3) are cross-manufacturer alternatives that provide documented operating temperature ranges, current ratings, and voltage specifications not listed for the original part. Both groups maintain functional compatibility for 3-position, 4.20mm pitch, shrouded header applications.

Q: Does the insulation height difference affect compatibility?

A: The insulation height variance between parts (0.490" to 0.504") is within acceptable mechanical tolerance for board-to-cable/wire header applications. This difference does not affect electrical performance or mating compatibility with corresponding receptacle connectors designed for the 4.20mm pitch standard.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the regulatory status of the original 0050361809 part.

Q: What packaging options are available?

A: Molex 0469990563 is supplied in bulk packaging, while 0039305038 and 1726470103 are supplied in tray packaging. TE Connectivity 2029056-3 and 2029113-3 are supplied in tray packaging, and 2029167-3 is supplied in bulk packaging. Packaging selection does not affect electrical or mechanical performance.

Q: Which substitute has the highest inventory availability?

A: Molex 1726470103 has the highest inventory availability at 17,635 units in stock, followed by Molex 0039305038 at 936 units. This makes 1726470103 the preferred choice for high-volume production requirements.

Q: Is the UL94 V-2 rating of part 1726470103 acceptable as a substitute for the V-0 rated original?

A: UL94 V-2 represents a lower flammability classification than V-0. Substitution is acceptable only if the application does not require V-0 compliance. For applications with explicit V-0 requirements, select from parts rated UL94 V-0: 0469990563, 0039305038, 2029056-3, 2029113-3, or 2029167-3.
