Molex 0901522334 Equivalent & Substitute Parts

Part Overview

The Molex 0901522334 is a 34-position receptacle connector featuring 0.100" (2.54mm) pitch, through-hole right-angle mounting, and gold-plated mating contacts. This connector is part of the C-Grid III 90152 series and is actively manufactured. The part is widely used in automotive, medical, telecommunications, and general-purpose applications requiring board-to-board connectivity with push-pull fastening.

Substitute parts are identified when product discontinuation, supply constraints, or application-specific requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0901522334 is determined by the following critical parameters:

Connector Type & Position Count: Must be receptacle with 34 positions
Pitch & Row Configuration: 0.100" (2.54mm) mating pitch with 2-row layout and 0.100" row spacing
Mounting & Orientation: Through-hole, right-angle mounting required
Contact Interface: Female socket contacts with gold mating finish
Fastening Mechanism: Push-pull fastening compatibility

The TE Connectivity AMP Connectors 535512-4 meets these core substitution criteria, sharing identical position count, pitch, row configuration, mounting style, contact type, and fastening mechanism.

Engineering Selection Recommendations

Primary Selection: The Molex 0901522334 is the recommended choice for new designs and active production. The part is actively manufactured, ROHS3 compliant, and carries a 3A current rating with a 350V voltage specification.

Substitute Selection: The TE Connectivity AMP Connectors 535512-4 is electrically and mechanically compatible for applications where the Molex part is unavailable. However, the following factors must be evaluated:

RoHS Compliance: The TE part is RoHS non-compliant, which may restrict use in regulated markets or applications with RoHS requirements.
Current Rating: The TE part is rated for 2A versus the Molex 3A rating. Applications requiring 3A operation must use the Molex part.
Product Status: The TE part is discontinued at DiGi Electronics, limiting long-term availability.
Operating Temperature: The TE part supports -55°C to 125°C, providing a wider upper temperature range than the Molex part (-55°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 535512-4 be used as a direct replacement for the Molex 0901522334?

A: The TE Connectivity part is mechanically and electrically compatible for mating and mounting. However, application-specific requirements must be verified. If the circuit requires 3A operation, the Molex part is mandatory. If RoHS compliance is required, the Molex part must be used.

Q: What are the key compatibility criteria for these connectors?

A: Compatibility is determined by: 34-position count, 0.100" (2.54mm) pitch, 2-row configuration with 0.100" row spacing, through-hole right-angle mounting, female socket contacts, gold mating finish, and push-pull fastening. Both parts meet these criteria.

Q: Are there differences in contact finish thickness?

A: The mating contact finish thickness is identical at 30.0µin (0.76µm). The post contact finish differs: Molex uses tin (118.1µin / 3.00µm) while TE uses tin-lead (50.0µin / 1.27µm).

Q: What is the impact of the 1A current rating difference?

A: The Molex part is rated for 3A while the TE part is rated for 2A. For applications requiring continuous current above 2A, the Molex part must be used to ensure safe operation within rated specifications.

Q: Does the TE part's wider operating temperature range make it preferable?

A: The TE part supports operation to 125°C versus the Molex part's 105°C upper limit. For applications requiring sustained operation above 105°C, the TE part provides additional thermal margin. However, this advantage is offset by RoHS non-compliance and lower current rating.

Q: What is the significance of the product status difference?

A: The Molex part is actively manufactured, ensuring ongoing availability and supply chain stability. The TE part is discontinued at DiGi Electronics, which may limit future procurement options and increase lead times through alternative distributors.
