Molex 0901200142 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0901200142 is an active-status vertical header connector featuring 22 positions with 0.100" (2.54mm) pitch spacing. This through-hole, unshrouded connector is designed for board-to-board or cable applications with solder termination and push-pull fastening. The component operates across -55°C to 125°C and meets UL94 V-0 flammability requirements with ROHS3 compliance. Substitute parts become necessary when addressing design revisions, supply chain constraints, or when legacy components require modern alternatives with equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901200142 is determined by the following critical parameters: connector type (Header, Breakaway), contact type (Male Pin), pitch spacing (0.100"/2.54mm), mounting method (Through Hole), termination method (Solder), and fastening type (Push-Pull). The substitute part TE Connectivity AMP Connectors 4-103327-0 shares these core electrical and mechanical characteristics, enabling functional equivalence despite differences in position count, series designation, and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0901200142 maintains active product status with current ROHS3 compliance, making it the preferred selection for new designs and applications requiring regulatory adherence. The TE Connectivity 4-103327-0 substitute is classified as obsolete with non-applicable RoHS status, limiting its suitability to legacy system maintenance or applications where regulatory compliance is not mandated. Selection between these parts must account for position count requirements: the Molex connector accommodates 22 positions while the TE Connectivity alternative provides 40 positions. Operating temperature range differs, with the Molex part supporting -55°C to 125°C versus the TE Connectivity part's -65°C to 105°C specification. Contact finish composition also varies, with the Molex part utilizing tin finish and the TE Connectivity part employing tin-lead finish.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103327-0 directly replace the Molex 0901200142 in existing designs?

A: Direct replacement is not recommended without design review. While both connectors share identical pitch spacing (0.100"/2.54mm), connector type, and mounting method, the TE Connectivity part provides 40 positions versus 22 positions in the Molex connector. PCB layout and mating connector compatibility must be verified before substitution.

Q: What are the primary differences affecting substitution decisions?

A: Key differences include position count (22 vs. 40), product status (Active vs. Obsolete), RoHS compliance (ROHS3 vs. Not applicable), operating temperature range (-55°C to 125°C vs. -65°C to 105°C), and contact finish composition (Tin vs. Tin-Lead). These parameters determine suitability for specific applications and regulatory environments.

Q: Is the TE Connectivity part suitable for new product designs?

A: The TE Connectivity 4-103327-0 is classified as obsolete and carries non-applicable RoHS status. For new designs requiring regulatory compliance and long-term supply assurance, the active-status Molex 0901200142 is the appropriate selection.

Q: How do packaging differences affect component procurement?

A: The Molex 0901200142 is supplied in Tray packaging with 994 pieces in stock, while the TE Connectivity 4-103327-0 is supplied in Bulk packaging with 3298 pieces available. Packaging format may influence handling, storage, and assembly line integration requirements.

Q: Are there mechanical compatibility concerns between these connectors?

A: Both connectors feature identical pitch spacing, square contact geometry, unshrouded design, and through-hole mounting. Mechanical compatibility depends on mating connector specifications and PCB footprint design. The position count difference (22 vs. 40) requires verification against circuit board layout and connector cavity requirements.
