Molex 0901522340 Equivalent & Substitute Parts

Part Overview

The Molex 0901522340 is a 40-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle board-to-board applications. This connector features gold-plated mating contacts, tin-plated posts, and is rated for 3A at 350V. The part is Active status and RoHS3 compliant, making it suitable for automotive, medical, telecommunications, and general-purpose applications. Equivalent parts are identified when functional requirements demand alternative sourcing due to inventory constraints, supply chain considerations, or application-specific compliance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901522340 is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish functional equivalence:

Critical Parameters for Substitution:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (40 positions) and pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" row spacing)
• Mounting style (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish at mating interface (Gold plating)
• Insulation material (Polyester, Glass Filled)

The TE Connectivity AMP Connectors part 2-535512-5 meets all critical substitution parameters. Both connectors share identical position counts, pitch specifications, row configurations, mounting orientations, and contact materials. Both employ push-pull fastening and solder termination. The gold-plated mating contacts and polyester glass-filled insulation are common to both parts, ensuring mechanical and electrical compatibility in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0901522340 is the primary specification for applications requiring RoHS3 compliance and tin-plated posts. This part is Active status with 862 units in stock and meets all automotive, medical, and telecommunications regulatory requirements.

The TE Connectivity 2-535512-5 serves as a functional substitute for applications where RoHS compliance is not mandated. This part is also Active status with higher inventory availability (1,528 units). The TE part supports an extended operating temperature range (-55°C to 125°C versus -105°C for Molex) and features UL94 V-0 flammability rating. However, the TE part is RoHS non-compliant and carries tin-lead post plating, making it unsuitable for regulated industries.

Current rating differences (3A for Molex versus 2A for TE) must be evaluated against circuit requirements. The TE part's lower current rating may limit its use in high-current applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-535512-5 be used as a direct replacement for the Molex 0901522340?

A: Mechanical and electrical compatibility exists for board-to-board applications due to matching position counts, pitch spacing, row configurations, and contact materials. However, regulatory compliance differs. The Molex part is RoHS3 compliant with tin plating; the TE part is RoHS non-compliant with tin-lead plating. Selection depends on application requirements and regulatory mandates.

Q: What are the key differences between these connectors?

A: The primary differences are RoHS compliance status, post plating composition (tin versus tin-lead), current rating (3A versus 2A), operating temperature upper limit (105°C versus 125°C), and flammability rating (TE part has UL94 V-0). Mechanical dimensions are nearly identical with minor variations in insulation height and contact post length.

Q: Are there any PCB layout considerations when switching between these parts?

A: Both connectors use identical 0.100" (2.54mm) pitch spacing and 2-row configuration. PCB footprints are compatible. Minor dimensional differences in insulation height (0.230" versus 0.238") and post length (0.114" versus 0.115") are within standard manufacturing tolerances and do not require PCB redesign.

Q: Which part should be selected for automotive applications?

A: The Molex 0901522340 is recommended for automotive applications due to RoHS3 compliance and tin plating, which align with automotive industry standards. The TE part's RoHS non-compliance and tin-lead plating make it unsuitable for most automotive specifications.

Q: What is the impact of the current rating difference?

A: The Molex part is rated for 3A while the TE part is rated for 2A. Applications requiring sustained currents above 2A must use the Molex part. For applications operating below 2A, both parts are functionally equivalent from a current-handling perspective.
