Substitute Part Grouping Explanation

Substitution between the TE Connectivity 350833-2 and 350833-4 is based on identical electrical and mechanical parameters that define functional compatibility. Both parts share the same base product number (350833) and maintain equivalence across all critical connector specifications.

The following parameters are identical between the main part and substitute, establishing direct substitutability:

• Connector type (Header)
• Contact type (Female Socket)
• Number of positions (4)
• Pitch - mating (0.250" / 6.35mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish - mating (Gold at 30.0µin / 0.76µm thickness)
• Insulation material (Polyamide/Nylon)
• Insulation height (0.550" / 13.97mm)
• Contact length - post (0.215" / 5.46mm)
• Contact shape (Circular)
• Contact material (Phosphor Bronze)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 - Unlimited)
• Series designation (Universal MATE-N-LOK)

Differences between parts are limited to packaging format and post-side contact finish specification, neither of which affects electrical or mechanical compatibility in the application interface.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 350833-2 and 350833-4 are active products suitable for direct substitution in applications requiring 4-position header connectors with 0.250" pitch and through-hole solder termination.

The 350833-4 offers RoHS compliance certification, making it the appropriate selection for applications subject to RoHS regulatory requirements. The 350833-2 carries "Not applicable" RoHS status, indicating it does not fall under RoHS scope or has not been certified for compliance.

The post-side contact finish differs between parts: the 350833-2 features tin-lead plating while the 350833-4 uses tin plating. This distinction reflects the RoHS compliance difference, as tin-lead finishes are restricted under RoHS directives. Both finishes are suitable for solder termination applications.

Packaging format differs between the two parts, with the 350833-2 supplied in standard packaging and the 350833-4 in bulk packaging. Selection between these options depends on procurement and inventory management requirements.

Both parts maintain identical electrical and mechanical specifications across all mating interface parameters, fastening mechanisms, and insulation properties. Selection between them should be based on regulatory compliance requirements and packaging preferences rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 350833-4 be used as a direct replacement for the 350833-2 in existing designs?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting method, and termination specifications. The electrical and mechanical interfaces are fully compatible. Selection between them depends on RoHS compliance requirements and packaging format preferences.

Q: What is the difference between the contact finishes on these two parts?

A: The 350833-2 uses tin-lead plating on the post-side contacts, while the 350833-4 uses tin plating. This difference corresponds to the RoHS compliance status of each part. Both finishes are compatible with solder termination processes. The mating-side contact finish (gold) is identical on both parts.

Q: Why does the 350833-4 have RoHS Compliant status while the 350833-2 does not?

A: The RoHS status difference reflects the post-side contact finish specification. The 350833-4 uses RoHS-compliant tin plating, while the 350833-2 uses tin-lead plating, which is restricted under RoHS directives. The RoHS status of the 350833-2 is listed as "Not applicable," indicating it does not meet RoHS requirements.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical specifications for connector type, contact material (phosphor bronze), contact finish thickness on the mating side (30.0µin), insulation material, and all other electrical interface parameters. Performance in the application is equivalent.

Q: What packaging formats are available for these parts?

A: The 350833-2 is supplied in standard packaging, while the 350833-4 is supplied in bulk packaging. Packaging selection depends on procurement volume and inventory management requirements. Both packaging formats contain the same connector specification.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS compliance requirements, the 350833-4 is the appropriate selection. For applications without RoHS requirements, either part is functionally equivalent. Verify regulatory requirements for your specific application before final part selection.

Q: Are the insulation and mechanical dimensions identical between these parts?

A: Yes. Both parts share identical insulation height (0.550"), contact length (0.215"), contact shape (circular), and all other mechanical dimensions. The physical form factor and mounting interface are identical.
