Substitute Part Grouping Explanation

The Molex 0347970202 can be substituted with the Molex 0347970201 based on strict parametric equivalence within the MX150 34797 series. Both parts share identical electrical and mechanical specifications:

• Same connector type (Plug) and contact configuration (Male Blade, 2-position)
• Identical pitch specification (0.138" / 4.60mm)
• Matching mounting method (Free Hanging In-Line)
• Identical termination method (Crimp) and fastening mechanism (Locking Ramp)
• Same series designation (MX150 34797)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

The primary difference is color (Natural vs. Black) and product status (Obsolete vs. Active). Color variation does not affect electrical or mechanical compatibility when the connector housing is used in applications where color is not a functional requirement.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0347970201 is the direct parametric equivalent for the obsolete Molex 0347970202. Both parts maintain identical electrical and mechanical specifications within the MX150 34797 series and carry equivalent regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected).

Selection of the 0347970201 is supported by its active product status, ensuring continued availability and supply chain reliability. The color difference (Black vs. Natural) represents the only functional distinction and does not impact electrical performance or mechanical compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0347970201 directly replace the 0347970202 in existing assemblies?

A: Yes. Both parts are parametrically equivalent within the MX150 34797 series, sharing identical connector type, position count, pitch, contact configuration, mounting method, and termination specifications. Substitution is valid from an electrical and mechanical standpoint.

Q: Does the color difference between Natural (0347970202) and Black (0347970201) affect compatibility?

A: Color is a cosmetic attribute and does not affect electrical or mechanical performance. Substitution is appropriate unless color specification is a documented functional requirement in the application design.

Q: Why is the 0347970202 listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The active status of the 0347970201 indicates that Molex continues to support this connector series through the black variant, making it the recommended choice for new procurement and ongoing system support.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) ratings. Regulatory and environmental compliance requirements are met equally by either part.

Q: What is the significance of the base product number 034797?

A: The base product number identifies the core connector design family. Both the 0347970202 and 0347970201 share the same base product number, confirming they are variants within the same product line with identical core specifications.
