Molex 0010883242 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010883242 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 24-position, 2-row header operates at 0.100" (2.54mm) pitch and features male pin contacts with solder termination. The connector is constructed with copper alloy contacts finished in tin and housed in a UL94 V-0 rated polyester glass-filled insulation body.

Substitute parts become necessary when the original part reaches end-of-life status, inventory constraints occur, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0010883242 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Material: Copper Alloy

Secondary Compatibility Factors:

• Connector Type: Header, Breakaway
• Style: Board to Board or Cable
• Shrouding: Unshrouded
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0

The identified substitute part TE Connectivity AMP Connectors 4-103324-0 shares the core electrical and mechanical parameters that define functional interchangeability. However, differences exist in position count, insulation material composition, contact finish specifications, and regulatory compliance status that must be evaluated for specific application requirements.

Engineering Selection Recommendations

Molex 0010883242 (Primary Selection): The Molex 0010883242 maintains active product status and ROHS3 compliance, making it the preferred choice for new designs and applications subject to RoHS regulations. This part is currently in stock with 934 units available. The active status ensures continued manufacturer support and availability for production requirements.

TE Connectivity 4-103324-0 (Substitute Consideration): The TE Connectivity 4-103324-0 is classified as obsolete and RoHS non-compliant. This part should be considered only in legacy system maintenance scenarios where the original Molex part is unavailable and the application does not require RoHS compliance. The 80-position configuration differs significantly from the 24-position main part, requiring circuit board redesign and connector footprint modification. The Tin-Lead contact finish and thermoplastic insulation material differ from the main part specifications.

Compliance Constraints: Applications requiring ROHS3 compliance must use the Molex 0010883242. The TE Connectivity substitute does not meet this regulatory requirement. The contact finish difference (Tin versus Tin-Lead) may affect solderability characteristics and long-term reliability in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103324-0 be used as a direct replacement for the Molex 0010883242?

A: No. While both connectors share identical pitch (0.100" / 2.54mm), row spacing, mounting type, and termination method, the TE Connectivity part has 80 positions compared to 24 positions in the Molex part. This requires complete circuit board redesign and connector footprint modification. Additionally, the TE Connectivity part is obsolete and RoHS non-compliant.

Q: What are the key electrical and mechanical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact type (male pin), mounting type (through hole, right angle), termination method (solder), and contact material (copper alloy). Deviations in these parameters prevent functional interchangeability.

Q: Does the insulation material difference affect performance?

A: The Molex part uses polyester glass-filled insulation while the TE Connectivity substitute uses thermoplastic insulation. Both materials achieve UL94 V-0 flammability rating. Material selection affects mechanical properties, temperature stability, and moisture absorption characteristics. Application-specific environmental conditions determine whether this difference is significant.

Q: What is the impact of the contact finish difference?

A: The Molex part features tin contact finish while the TE Connectivity substitute uses tin-lead finish. This difference affects solderability, contact resistance, and long-term reliability. Tin-lead finishes are associated with older manufacturing standards and may not be suitable for applications requiring lead-free assembly processes.

Q: Why is the TE Connectivity part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. This creates supply chain risk and limits availability for future production runs. The Molex 0010883242 maintains active status with confirmed inventory of 934 units.

Q: Are there packaging differences between these parts?

A: Yes. The Molex 0010883242 is packaged in tubes, while the TE Connectivity 4-103324-0 is supplied in bulk packaging. Packaging affects handling, storage, and component counting procedures in manufacturing environments.

Q: What compliance certifications apply to each part?

A: The Molex 0010883242 is ROHS3 compliant and REACH unaffected. The TE Connectivity 4-103324-0 is RoHS non-compliant with undefined REACH status. Applications subject to environmental regulations must use the Molex part.
