Molex 0022436075 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022436075 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 7-position connector operates at 2.5mm pitch and features kinked pin solder termination with push-pull fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity across automotive, industrial, medical, and telecommunications applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022436075 is determined by the following critical parameters:

• Connector Type & Contact Type: Must be Header with Male Pin contacts
• Pitch & Position Count: Must maintain 0.098" (2.50mm) pitch with 7 positions in single row configuration
• Mounting & Termination: Must support through-hole mounting with solder termination
• Board-to-Cable/Wire Style: Must maintain the same connection topology
• Shrouding: Must provide shrouded design for mechanical protection
• Material & Compliance: Must use brass contacts with tin finish and maintain UL94 V-0 and ROHS3 compliance

The Molex 0099990991 (Mini-SPOX 5267 series) satisfies these substitution criteria while offering an active product status alternative to the obsolete 0022436075.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0099990991 is the designated manufacturer substitute for the obsolete Molex 0022436075. Both connectors maintain identical pitch, position count, and mounting configuration, ensuring mechanical and electrical compatibility at the board interface level.

Key considerations for selection:

• Product Status: The 0099990991 carries active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 0022436075.
• Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for automotive, industrial, medical, and telecommunications applications.
• Shrouding Enhancement: The 0099990991 features 4-wall shrouding versus 3-wall on the original part, providing increased mechanical protection and EMI shielding.
• Fastening Mechanism Difference: The 0099990991 uses detent lock fastening instead of push-pull. This represents a functional change requiring mechanical interface assessment during integration.
• Contact Geometry: The 0099990991 employs circular contacts versus square contacts on the 0022436075. This difference does not affect electrical performance but may impact insertion force characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 0099990991 be used as a direct drop-in replacement for the 0022436075?

A: The 0099990991 maintains identical pitch (2.50mm), position count (7), and through-hole mounting configuration. However, the fastening mechanism differs (detent lock versus push-pull), requiring mechanical interface validation. Contact geometry also differs (circular versus square), which may affect insertion force. Electrical compatibility is confirmed.

Q: What is the significance of the shrouding difference (3-wall versus 4-wall)?

A: The 4-wall shrouding on the 0099990991 provides enhanced mechanical protection and improved EMI shielding compared to the 3-wall design of the 0022436075. This represents an improvement in connector robustness without affecting mating compatibility.

Q: Are both connectors suitable for the same applications?

A: Yes. Both the 0022436075 and 0099990991 are specified for automotive, general purpose, industrial, medical, and telecommunications applications. Both maintain UL94 V-0 flammability certification and ROHS3 compliance.

Q: What is the impact of the different insulation materials?

A: The 0022436075 uses polyester glass-filled insulation, while the 0099990991 uses polyamide (PA66) glass-filled insulation. Both materials provide equivalent electrical insulation and mechanical properties for the specified applications. Polyamide offers slightly improved chemical resistance in certain industrial environments.

Q: Does the contact finish thickness difference affect performance?

A: The 0099990991 specifies 160.0µin (4.06µm) tin finish thickness on both mating and post contacts, compared to 100.0µin (2.54µm) on the 0022436075 mating contacts. The increased thickness on the substitute part provides enhanced corrosion resistance and extended contact life, representing a performance improvement.

Q: Are there any packaging differences between these parts?

A: The 0022436075 is supplied in standard packaging, while the 0099990991 is supplied in bulk packaging. This affects procurement and handling procedures but does not impact connector functionality or performance.
