Substitute Part Grouping Explanation

Substitution of the Molex 0022282353 is determined by strict equivalence across the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 35 positions in single-row configuration
• Connector Type and Orientation: Header, breakaway design with right-angle through-hole mounting
• Contact Configuration: Male pin contacts with gold-plated mating surfaces and tin-plated posts
• Shrouding and Mechanical Form: Single-wall shrouded construction with square contact shape
• Termination Method: Solder termination with push-pull or friction lock fastening
• Material and Compliance: Polyamide nylon insulation, UL94 V-0 flammability rating, RoHS compliance

The substitute part Molex 0022281352 meets all these criteria while offering active product status and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022281352 is the recommended substitute for the obsolete Molex 0022282353. Both connectors share identical mechanical and electrical interface specifications, ensuring direct form-fit-function compatibility in existing designs.

The substitute part offers the following advantages:

• Active Product Status: The 0022281352 maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Enhanced Electrical Specifications: The substitute provides defined operating temperature range (-40°C ~ 105°C) and voltage rating (600VAC/DC), supporting broader application requirements.
• Compliance Alignment: Both parts maintain UL94 V-0 flammability rating, RoHS compliance, and MSL 1 moisture sensitivity classification, meeting automotive, medical, and telecommunications standards.
• Fastening Mechanism Difference: The substitute employs friction lock fastening instead of push-pull. This represents a functional change in mating security but does not affect electrical or mechanical interface compatibility.

Selection of the 0022281352 is appropriate for new designs and legacy system updates where the 0022282353 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Are the 0022282353 and 0022281352 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (35), mounting orientation (right-angle through-hole), contact dimensions, and shrouding configuration. Direct substitution is mechanically feasible.

Q: What is the difference between push-pull and friction lock fastening?

A: Push-pull fastening uses a mechanical latch mechanism for mating security. Friction lock relies on contact pressure and insertion force. Both methods secure the mated connector pair. The friction lock design in the 0022281352 does not compromise electrical continuity or mechanical retention in standard applications.

Q: Can I use the 0022281352 in automotive applications?

A: Yes. Both parts are rated for automotive applications and maintain equivalent compliance certifications (UL94 V-0, RoHS). The substitute's defined operating temperature range (-40°C ~ 105°C) and voltage rating (600VAC/DC) support automotive environmental and electrical requirements.

Q: What is the significance of the contact finish thickness difference?

A: The main part specifies 30.0µin (0.76µm) gold plating on mating contacts, while the substitute specifies 3.00µin (0.076µm). Both thicknesses provide adequate corrosion resistance and electrical conductivity for the KK254 series application. The thinner plating on the substitute reflects current manufacturing standards for this connector family.

Q: Are there any design considerations when transitioning from the 0022282353 to the 0022281352?

A: The primary design consideration is the fastening mechanism change from push-pull to friction lock. Verify that the mating connector or cable assembly is compatible with friction lock engagement. No changes to PCB layout, contact spacing, or electrical routing are required.

Q: What is the inventory status of these parts?

A: The 0022282353 (obsolete) has 1100 pieces in stock. The 0022281352 (active) has 766 pieces in stock. For long-term procurement, the active part is recommended.
