Molex 0022436074 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022436074 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 essential for ongoing system support and new design implementations. The substitute part 0099990991 provides equivalent electrical and mechanical functionality while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

The Molex 0099990991 qualifies as a functional substitute for the 0022436074 based on the following critical parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 7
• Number of rows: 1
• Pitch - mating: 0.098" (2.50mm)
• Mounting type: Through hole
• Style: Board to cable/wire
• Contact material: Brass
• Contact finish: Tin
• Insulation material: Glass filled polymer
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Applications: Automotive, General Purpose, Industrial, Medical, Telecommunications

Differences:

• Shrouding: 3 wall (original) vs. 4 wall (substitute)
• Fastening type: Push-pull (original) vs. Detent lock (substitute)
• Contact shape: Square (original) vs. Circular (substitute)
• Insulation height: 0.283" (original) vs. 0.232" (substitute)
• Series designation: SPOX 42249 (original) vs. Mini-SPOX 5267 (substitute)

These differences do not prevent functional substitution in applications where the mating connector accommodates the geometric and fastening variations.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0099990991 is the designated manufacturer substitute for the obsolete 0022436074. Both parts maintain identical electrical and mechanical compatibility at the core interface level: 7-position, 2.5mm pitch, through-hole header configuration with male pins and brass tin-plated contacts.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. Both parts satisfy UL94 V-0 flammability requirements and ROHS3 compliance, making them suitable for automotive, industrial, medical, and telecommunications applications.

The geometric differences—increased shrouding wall count (4 vs. 3), detent lock fastening (vs. push-pull), and reduced insulation height—do not compromise electrical performance. Mechanical compatibility depends on the mating connector design. Systems originally designed for the 0022436074 can accommodate the 0099990991 provided the mating connector accepts the detent lock mechanism and the reduced insulation height does not create clearance conflicts.

Frequently Asked Questions (FAQ)

Q: Can the 0099990991 directly replace the 0022436074 in existing designs?

A: Electrical compatibility is assured due to matching pitch, position count, contact material, and finish specifications. Mechanical compatibility requires verification that the mating connector accommodates the detent lock fastening mechanism and the reduced insulation height of 0.232" versus 0.283".

Q: What is the significance of the shrouding wall count difference?

A: The substitute part features 4-wall shrouding compared to 3-wall on the original. This provides enhanced mechanical protection and keying. The mating connector must be designed to accept this configuration.

Q: Are there differences in contact geometry that affect mating?

A: Yes. The original part has square contacts while the substitute has circular contacts. Both maintain the same mating contact length of 0.138" (4.60mm). The mating connector must accommodate the circular contact geometry.

Q: How do the fastening mechanisms differ?

A: The original uses push-pull fastening while the substitute uses detent lock. These are mechanically distinct engagement methods. The mating connector must be compatible with the detent lock mechanism.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 0022436074 and 0099990991 are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for flammability. Both carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the availability status of each part?

A: The 0022436074 is obsolete with 689 pieces in stock. The 0099990991 is active with 848 pieces in stock, providing superior long-term supply assurance.

Q: Do the insulation material differences affect performance?

A: The original uses polyester glass-filled insulation while the substitute uses polyamide (PA66) nylon 6/6 glass-filled material. Both achieve UL94 V-0 rating. The polyamide material in the substitute offers enhanced chemical resistance and thermal stability typical of nylon-based formulations.
