Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0757571432 is determined by the following critical parameters:

• Connector type (Header, Breakaway)
• Number of positions (6) and row configuration (2 rows)
• Pitch specification (0.138" / 4.60mm mating pitch)
• Row spacing (0.236" / 6.00mm)
• Contact type (Male Blade)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Shrouding configuration (Unshrouded)
• Material compliance (UL94 V-0, ROHS3)

The Molex 0757571431 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the MX150 75757 series.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0757571431 is the active equivalent for the obsolete Molex 0757571432. Both components maintain identical electrical and mechanical specifications across all critical mating parameters, including pitch, row spacing, contact configuration, and fastening mechanism.

The primary difference between these parts is the contact post length. The 0757571431 features a shorter post length (0.120" / 3.05mm) compared to the 0757571432 (0.187" / 4.75mm), resulting in a reduced overall contact length. This dimensional variation does not affect mating compatibility or electrical performance when used in applications designed for the MX150 75757 series.

Both parts maintain identical compliance certifications: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. The 0757571431 is currently in active production with established supply availability, making it the appropriate selection for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0757571431 directly replace the 0757571432 in existing applications?

A: Yes. The 0757571431 maintains identical mating pitch (4.60mm), row spacing (6.00mm), contact type, and fastening mechanism. The difference in post length does not affect mating compatibility with standard MX150 75757 series receptacles.

Q: What is the significance of the contact post length difference?

A: The contact post length determines the depth of solder connection on the PCB. The 0757571431 has a shorter post (0.120" vs 0.187"), which may require evaluation of PCB pad design and solder joint geometry. Applications with established PCB layouts should confirm compatibility with the reduced post length.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts carry identical certifications: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: What is the packaging difference?

A: The 0757571432 packaging information is not specified in available data. The 0757571431 is supplied in Tube packaging.

Q: Why is the 0757571432 obsolete?

A: The 0757571432 has been superseded by the 0757571431 within the MX150 75757 series product line. The 0757571431 is the active production equivalent.

Q: Are both parts from the same manufacturer series?

A: Yes. Both components are part of the Molex MX150 75757 series, confirming design compatibility and interchangeability within the series specifications.
