Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0050361678 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Plug with male pin contacts
• Position Count & Row Configuration: 2 positions, 2 rows
• Row Spacing: 0.165" (4.20mm)
• Contact Termination: Crimp
• Fastening Mechanism: Locking Ramp
• Compliance Standards: ROHS3 Compliant, MSL 1

Three substitute parts meet these core electrical and mechanical requirements. However, substitutes differ in mounting type and series designation, which affects physical integration into existing designs.

Parameter Comparison

Engineering Selection Recommendations

Molex 0469930211 is the primary substitute for panel mount applications. This part maintains identical mounting type (panel mount) and color (black) as the original 0050361678, ensuring direct mechanical compatibility in existing PCB layouts. Both parts share the same HTSUS classification (8536.69.4030), confirming equivalent electrical and mechanical characteristics. The 0469930211 is active with substantial inventory availability (22,790 pcs).

Molex 0469990275 is functionally equivalent but requires design modification due to free hanging (in-line) mounting type. This part is suitable only when the application can accommodate in-line connector orientation. It maintains the Mini-Fit Jr 5559 series designation and black color. Inventory availability is high (20,472 pcs).

Molex 0039013029 is functionally equivalent but differs in both mounting type (free hanging) and color (natural). This part is suitable only when application design permits in-line mounting and color variation is acceptable. It shares the Mini-Fit Jr 5559 series with the original part. Inventory availability is adequate (11,036 pcs).

All three substitutes are ROHS3 compliant with MSL 1 rating, matching the original part's compliance profile.

Frequently Asked Questions (FAQ)

Q: Can 0469930211 be used as a direct replacement for 0050361678?

A: Yes. Both parts are panel mount connectors with identical row spacing (0.165"), 2-position configuration, male pin contacts, crimp termination, and locking ramp fastening. Both are black and ROHS3 compliant. No PCB layout modification is required.

Q: What is the difference between panel mount and free hanging (in-line) mounting?

A: Panel mount connectors are designed for perpendicular insertion into PCB edge connectors or mating receptacles mounted on the same board. Free hanging (in-line) connectors are designed for cable-to-board or cable-to-cable applications where the connector remains in-line with the cable. Substituting panel mount with in-line requires design modification.

Q: Why does 0039013029 have a different color (natural) than the original?

A: Color is a cosmetic specification that does not affect electrical or mechanical function. Natural (undyed) polyamide is the default material color, while black requires pigmentation. If color matching is required for assembly or identification purposes, 0469930211 or 0469990275 (both black) are preferred.

Q: Are all substitutes compatible with the same crimp contacts?

A: All substitutes use crimp termination with identical row spacing and position count. Contact compatibility depends on the specific contact part number used in the original design. Verify contact part numbers with Molex documentation to ensure mechanical fit within the housing cavity.

Q: What is the significance of the different insulation materials (PA6 vs PA66)?

A: Both polyamide 6 (PA6) and polyamide 6/6 (PA66) are engineering thermoplastics suitable for connector housings. PA66 offers slightly higher thermal stability and rigidity. Both materials are ROHS3 compliant. Material selection does not affect electrical performance for this connector category.

Q: Is inventory availability a factor in part selection?

A: Inventory levels indicate supply continuity. 0469930211 has the highest inventory (22,790 pcs), followed by 0469990275 (20,472 pcs) and 0039013029 (11,036 pcs). For long-term production, higher inventory provides supply security.
