Molex 0022438020 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022438020 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 2-position connector with 2.5mm pitch serves general purpose, automotive, industrial, medical, and telecommunications applications. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022438020 is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (2)
• Pitch - mating (0.098" / 2.50mm)
• Mounting type (Through Hole)
• Style (Board to Cable/Wire)
• Contact material (Brass)
• Contact finish (Tin)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

The Molex 0099990986 satisfies all primary substitution criteria. Both connectors share identical contact configuration, pitch spacing, mounting methodology, and material compliance requirements. Differences in shrouding design (4 Wall vs. 3 Wall), fastening mechanism (Detent Lock vs. Push-Pull), insulation material composition (Polyamide vs. Polyester), and contact geometry (Circular vs. Square) represent secondary design variations that do not prevent functional substitution in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0099990986 is the designated manufacturer substitute for the obsolete Molex 0022438020. Both connectors maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for automotive, industrial, medical, and telecommunications applications.

The substitute part transitions from the SPOX 42267 series to the Mini-SPOX 5267 series, representing an active product line with ongoing manufacturing support. This transition addresses the obsolescence status of the original part while preserving core electrical and mechanical compatibility.

Physical design differences include increased shrouding (4 Wall vs. 3 Wall), modified fastening mechanism (Detent Lock vs. Push-Pull), and altered insulation geometry. These variations do not compromise functional substitution in applications where connector pitch, contact configuration, and material compliance are the primary selection criteria.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0099990986 directly replace the 0022438020 in existing designs?

A: The 0099990986 provides functional equivalence for the core connector interface. However, physical design differences in shrouding height, fastening mechanism, and insulation profile may require mechanical validation in space-constrained applications or systems with specific mating force requirements.

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

A: The primary differences are shrouding design (3 Wall vs. 4 Wall), fastening type (Push-Pull vs. Detent Lock), contact geometry (Square vs. Circular), and insulation material composition (Polyester vs. Polyamide). Contact pitch, position count, mounting type, and material compliance remain identical.

Q: Are both connectors suitable for automotive applications?

A: Both connectors are rated for automotive applications and maintain UL94 V-0 flammability compliance and ROHS3 certification, meeting automotive regulatory requirements.

Q: What is the difference in insulation height between these parts?

A: The 0022438020 has an insulation height of 0.283" (7.19mm), while the 0099990986 measures 0.232" (5.90mm). This 0.051" (1.29mm) reduction may impact board layout and clearance considerations in compact designs.

Q: Does the change in fastening type affect mating reliability?

A: The 0022438020 uses Push-Pull fastening, while the 0099990986 employs Detent Lock fastening. Both mechanisms provide secure mating; however, the detent lock design may offer improved retention in vibration-prone environments typical of automotive and industrial applications.

Q: Are there inventory considerations for these parts?

A: The 0022438020 is obsolete with limited remaining stock (1113 pcs). The 0099990986 is an active product with current inventory availability (1210 pcs), ensuring long-term procurement viability.
