Substitute Part Grouping Explanation

Substitution of the Molex 0348996021 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical connector type (Plug housing)
• Identical number of positions (6)
• Identical pitch specification (0.157" / 4.00mm)
• Identical contact type (Blade Pin)
• Identical contact termination method (Crimp)
• Identical mounting configuration (Free Hanging, In-Line)
• Identical fastening mechanism (Latch Lock)
• Identical color (Gray)
• Identical moisture sensitivity rating (MSL 1)

The Molex 0348996091 satisfies all substitution criteria as a direct equivalent within the MXP120 34899 series, with the primary distinction being active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0348996091 is the direct functional equivalent for the obsolete 0348996021. Selection of the substitute part is justified on the following basis:

• Complete electrical and mechanical parameter equivalence across all specified dimensions and contact configurations
• Active product status ensuring continued availability and supply chain reliability
• RoHS compliance, meeting current environmental and regulatory requirements for new designs and procurement cycles
• Identical series classification (MXP120 34899) confirming design compatibility within the connector family

For applications currently utilizing the 0348996021, transition to the 0348996091 presents no functional or dimensional constraints.

Frequently Asked Questions (FAQ)

Q: Are the 0348996021 and 0348996091 mechanically interchangeable?

A: Yes. Both parts share identical pitch (0.157" / 4.00mm), position count (6), mounting type (free hanging in-line), and fastening mechanism (latch lock). No mechanical modifications are required for substitution.

Q: What is the primary reason for substituting the 0348996021?

A: The 0348996021 is classified as obsolete. The 0348996091 provides an active, currently manufactured equivalent with identical electrical and mechanical specifications.

Q: Does the substitute part require different contact specifications?

A: No. Both parts use identical blade pin contacts with crimp termination. Existing contact assemblies and termination tooling remain compatible.

Q: What is the significance of the RoHS compliance difference?

A: The 0348996091 is RoHS compliant, meeting current environmental regulations. The 0348996021 is non-compliant. For new designs or procurement requiring regulatory compliance, the 0348996091 is the appropriate selection.

Q: Are there any differences in moisture sensitivity or storage requirements?

A: No. Both parts carry identical MSL 1 (Unlimited) ratings, indicating no moisture sensitivity constraints for storage or handling.

Q: Can the 0348996091 be used in existing assemblies designed for the 0348996021?

A: Yes. Complete parameter equivalence ensures direct substitution without design modifications or re-qualification requirements.
