Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0050291663 are qualified based on the following critical parameters that determine functional interchangeability:

• Connector Type & Contact Type: All substitutes maintain plug configuration with male pin contacts
• Position Count & Pitch: All substitutes provide 3 positions at 0.165" (4.20mm) pitch
• Contact Termination & Fastening: All substitutes use crimp termination with locking ramp fastening
• Electrical & Environmental Compliance: All substitutes maintain ROHS3 compliance and MSL 1 rating

Substitutes are differentiated by:

• Series designation (Mini-Fit Jr 5559 vs. Mini-Fit Jr 172646)
• Mounting configuration (Panel Mount vs. Free Hanging)
• Housing color (Black vs. Natural)
• Packaging format (Bulk vs. Tray)
• Product status (Active vs. Obsolete)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Molex 0469990290

This part provides direct functional equivalence to the 0050291663 within the same Mini-Fit Jr 5559 series. Both maintain identical electrical and mechanical specifications including 3-position, 4.20mm pitch, panel mount configuration, and black housing. The 0469990290 carries active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance.

Alternative Substitute: Molex 1726460313

This part offers functional equivalence with transition to the newer Mini-Fit Jr 172646 series. It maintains all critical parameters: 3-position, 4.20mm pitch, panel mount, crimp termination, and locking ramp fastening. The 1726460313 is active status with ROHS3 compliance and represents a modern series alternative with significantly higher inventory availability.

Conditional Substitute: Molex 0039014037

This part maintains electrical and mechanical compatibility but differs in mounting configuration (free hanging in-line versus panel mount) and housing color (natural versus black). Selection of this part requires design verification that free hanging mounting is acceptable for the application. This part is active status with ROHS3 compliance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -40°C to 105°C operating temperature range, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can Molex 0469990290 directly replace 0050291663 in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications within the Mini-Fit Jr 5559 series: 3-position, 0.165" pitch, male pin contacts, crimp termination, locking ramp fastening, and panel mount configuration. The primary difference is product status (active versus obsolete) and packaging format.

Q: What is the key difference between 0469990290 and 1726460313?

A: Both provide functional equivalence but represent different series generations. The 0469990290 remains within Mini-Fit Jr 5559 series, while 1726460313 transitions to Mini-Fit Jr 172646 series. Both maintain identical position count, pitch, contact type, and mounting configuration. Series transition may require design review depending on connector interface specifications.

Q: Why is Molex 0039014037 listed as a substitute if the mounting type differs?

A: The 0039014037 maintains all critical electrical and contact specifications (3-position, 4.20mm pitch, male pin, crimp termination, locking ramp). However, the free hanging in-line mounting differs from the panel mount configuration of the original part. This substitute is applicable only when the application design can accommodate in-line mounting or when the connector will be used in a different assembly context.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes (0469990290, 0039014037, 1726460313) carry ROHS3 compliance certification, matching the regulatory status of the original 0050291663 part.

Q: What packaging options are available for these substitutes?

A: The 0469990290 and 0039014037 are supplied in bulk packaging, while 1726460313 is supplied in tray packaging. Packaging selection may impact procurement logistics and handling procedures but does not affect electrical or mechanical performance.

Q: Do all substitutes operate across the same temperature range?

A: Yes. All substitute parts operate across -40°C to 105°C, matching the original part specification and ensuring thermal compatibility in equivalent applications.
