Molex 0022436040 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022436040 is a shrouded vertical rectangular connector header with 4 positions at 2.5mm pitch, designed for through-hole mounting in board-to-cable/wire applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The part serves general purpose, automotive, industrial, medical, and telecommunications applications where reliable header connectivity is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022436040 is based on the following critical parameters that must remain constant:

• Pitch - Mating: 0.098" (2.50mm)
• Number of Positions: 4
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Style: Board to Cable/Wire
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The Molex 0099990988 qualifies as a functional equivalent because it maintains all critical mating and mounting parameters. While secondary characteristics differ (shrouding design, contact shape, fastening mechanism, and insulation material composition), these variations do not prevent electrical or mechanical compatibility in applications where the original part was specified.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0099990988 is an active product suitable for replacing the obsolete Molex 0022436040 in new designs and procurement scenarios. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for automotive, industrial, medical, and telecommunications applications.

The substitute part offers improved availability (4368 units in stock versus 1078 units) and active manufacturer support. The Mini-SPOX 5267 series provides enhanced shrouding (4-wall versus 3-wall design) and detent lock fastening, which may provide superior mating security in applications subject to vibration or mechanical stress.

Physical envelope differences exist: the substitute part has a reduced insulation height (5.90mm versus 7.19mm) and slightly different contact post length (4.60mm versus 3.30mm). These dimensional variations require verification against PCB layout and mating connector specifications before implementation.

Frequently Asked Questions (FAQ)

Q: Are the mating pitch and position count identical between these parts?

A: Yes. Both the 0022436040 and 0099990988 maintain 0.098" (2.50mm) pitch and 4-position single-row configuration, ensuring compatibility with existing mating connectors and PCB footprints designed for the original part.

Q: What are the key physical differences between these connectors?

A: The substitute part features 4-wall shrouding compared to 3-wall on the original, a circular contact shape versus square, detent lock fastening instead of push-pull, and reduced insulation height (5.90mm versus 7.19mm). The contact post length also differs slightly (4.60mm versus 3.30mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both.

Q: What is the primary reason for substitution?

A: The original part (0022436040) is classified as obsolete. The 0099990988 is an active product with superior availability and ongoing manufacturer support, making it the appropriate choice for new procurement and design continuity.

Q: Will the substitute part fit existing PCB layouts?

A: The mating interface and pitch are identical, so the substitute will mate with existing connectors. However, the reduced insulation height (5.90mm versus 7.19mm) may affect board clearance. PCB layout verification is necessary before implementation.

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

A: Push-pull fastening uses manual force to connect and disconnect. Detent lock fastening provides mechanical retention through a locking mechanism, offering enhanced security against unintended disconnection in vibration-prone environments.
