Molex 0901200934 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0901200934 is a vertical rectangular connector header designed for through-hole mounting applications. This 14-position, single-row connector operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts for reliable solder termination. The connector is classified as Active product status with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility is required across compatible connector families.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901200934 is determined by the following critical parameters:

• Connector Type: Header configuration with male pin contacts
• Number of Positions: 14-position layout
• Pitch - Mating: 0.100" (2.54mm) standard spacing
• Mounting Type: Through-hole solder termination
• Contact Configuration: Square male pins with gold mating finish
• Shrouding: Unshrouded design
• Fastening Type: Push-Pull mechanism

The Hirose Electric Co Ltd A2-14PA-2.54DSA(71) meets these core substitution criteria. Both connectors share identical pitch, position count, mounting method, and contact type, enabling direct functional replacement in board-to-board and cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0901200934 and Hirose A2-14PA-2.54DSA(71) are Active product status connectors with full RoHS and UL94 V-0 compliance. Selection between these parts should be based on the following factors:

Molex 0901200934 is suitable for applications requiring the extended operating temperature range of -55°C to 125°C. This part features ROHS3 compliance and is available in tray packaging.

Hirose A2-14PA-2.54DSA(71) is suitable for applications operating within -55°C to 85°C temperature limits. This part features standard RoHS compliance and is available in bulk packaging. The Hirose connector includes specified current and voltage ratings (3A at 200V), providing additional electrical performance documentation.

Both connectors maintain identical mechanical and electrical interface specifications for the 14-position, 2.54mm pitch header configuration, ensuring functional interchangeability in board-to-board and cable applications.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A2-14PA-2.54DSA(71) directly replace the Molex 0901200934 in all applications?

A: Direct replacement is possible for applications operating within the Hirose connector's temperature range of -55°C to 85°C. Applications requiring operation above 85°C must use the Molex part to maintain the -55°C to 125°C specification.

Q: What are the key mechanical compatibility factors between these connectors?

A: Both connectors share identical pitch (0.100" / 2.54mm), position count (14), contact type (male pin), and mounting method (through-hole solder). These parameters ensure mechanical and electrical interface compatibility.

Q: Are there differences in contact dimensions between these parts?

A: Yes. The Molex 0901200934 has a contact length of 0.266" (6.75mm) mating and 0.114" (2.90mm) post length. The Hirose A2-14PA-2.54DSA(71) has a contact length of 0.236" (6.00mm) mating and 0.118" (3.00mm) post length. These dimensional differences may affect fit in specific connector housings or mating applications.

Q: What packaging differences exist between these parts?

A: The Molex 0901200934 is supplied in tray packaging, while the Hirose A2-14PA-2.54DSA(71) is supplied in bulk packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Do both connectors meet the same compliance standards?

A: Both connectors are UL94 V-0 rated and RoHS compliant. The Molex part carries ROHS3 compliance, while the Hirose part carries standard RoHS compliance. Both have MSL 1 (Unlimited) moisture sensitivity ratings.
