Molex 0901220960 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0901220960 is an 80-position, 2-row rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This unshrouded header features a 0.100" (2.54mm) pitch and is part of the C-Grid III 90122 series. The connector is actively manufactured and widely used in automotive and general-purpose applications. Equivalent parts may be required due to supply chain considerations, design revisions, or specific compliance requirements in target markets.

Key Parameters

Substitute Part Grouping Explanation

The 3M 2380-5121TG qualifies as an equivalent substitute for the Molex 0901220960 based on the following critical parameters:

Matching Parameters:

• 80-position, 2-row configuration
• 0.100" (2.54mm) mating pitch
• 0.100" (2.54mm) row spacing
• Through-hole, right-angle mounting
• Male pin contact type
• Solder termination
• Push-pull fastening
• Unshrouded design
• Gold mating contact finish
• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity

Differences Noted: The substitute part exhibits variations in contact geometry, contact finish thickness specifications, insulation material composition, and compliance certifications. These differences do not affect mechanical or electrical interchangeability for standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Molex 0901220960 is the primary choice for applications requiring ROHS3 compliance and polyester-based insulation material. This part maintains active production status with established supply availability.

3M 2380-5121TG serves as a functional equivalent for applications where RoHS compliance is not mandated. The substitute exhibits identical mechanical and electrical interface characteristics, including pitch, position count, mounting configuration, and contact finish specifications. The thermoplastic insulation material and tin-lead post finish represent the primary material-level differences. Selection between these parts should be based on specific compliance requirements and supply chain constraints rather than functional performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0901220960 and 3M 2380-5121TG mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), position count (80), and mounting configuration (through-hole, right-angle). Physical dimensions and board footprints are compatible for direct substitution.

Q: What is the primary compliance difference between these parts?

A: The Molex 0901220960 is ROHS3 compliant, while the 3M 2380-5121TG is RoHS non-compliant. Applications subject to RoHS regulations must use the Molex part.

Q: Do the different insulation materials affect performance?

A: Both polyester and thermoplastic insulation materials meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. Material selection does not impact electrical or mechanical performance for standard applications.

Q: Can the tin-lead post finish of the 3M part be used in lead-free soldering processes?

A: Post finish composition does not prevent lead-free soldering compatibility. However, applications with specific lead-free requirements should reference the Molex part's tin post finish specification.

Q: What packaging formats are available?

A: The Molex 0901220960 is supplied in standard packaging. The 3M 2380-5121TG is available in bulk packaging format.
