Molex 0010897243 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010897243 is a vertical rectangular connector header designed for through-hole mounting applications. This 24-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-board and cable interconnection requirements across automotive, medical, telecommunications, and general-purpose applications. The part is currently active in production with 692 units in stock. Substitute parts may be required due to design changes, supply chain considerations, or specific application requirements that align with alternative connector geometries and material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010897243 is determined by strict alignment with the following critical parameters:

• Connector Configuration: 24 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
• Contact Interface: Male pin, square contact shape, solder termination
• Mounting Architecture: Through-hole, push-pull fastening, unshrouded design
• Electrical & Material Compliance: UL94 V-0 flammability rating, MSL 1 classification
• Mechanical Compatibility: Board-to-board or cable style, breakaway or cuttable connector type

The substitute parts listed below meet these core substitution criteria. Variations in contact length, insulation height, contact finish composition, and product status are documented but do not disqualify substitution eligibility when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Molex 0010897243 is the primary specification. This part maintains active production status, ROHS3 compliance, and LCP glass-filled insulation material. Selection of this part is appropriate for new designs and applications requiring current manufacturing support.

TE Connectivity 4-102977-0-12 is classified as obsolete and does not meet ROHS3 compliance requirements. This part is suitable only for legacy system maintenance or repair applications where existing inventory must be matched. The thermoplastic insulation material and tin-lead contact finish differ from the primary specification. New designs should not incorporate this part.

Harwin M20-9761246 maintains active production status and ROHS3 compliance. This part features polyamide (PA6T) nylon 6T insulation and tin mating contact finish, differing from the primary specification. The overall contact length is 0.452" (11.48mm) compared to 0.520" (13.21mm) for the Molex part, and the insulation height is 0.100" (2.54mm) versus 0.090" (2.29mm). These dimensional variations may affect board layout and mating interface geometry. The Harwin part is suitable for applications where these mechanical differences are accommodated by design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-102977-0-12 be used as a direct replacement for the Molex 0010897243?

A: The TE Connectivity part shares the same 24-position, 2-row, 0.100" (2.54mm) pitch configuration and push-pull fastening. However, the part is obsolete and RoHS non-compliant. Substitution is limited to legacy applications where existing inventory must be matched. The thermoplastic insulation and tin-lead contact finish differ from the primary specification.

Q: What are the key dimensional differences between the Molex and Harwin parts?

A: The Harwin M20-9761246 has an overall contact length of 0.452" (11.48mm) compared to 0.520" (13.21mm) for the Molex part. The insulation height is 0.100" (2.54mm) versus 0.090" (2.29mm). These differences affect the mating depth and board-to-board spacing. Verify that PCB layout and mating connector geometry accommodate these variations.

Q: Are all three parts suitable for automotive applications?

A: The Molex 0010897243 is specified for automotive applications. The TE Connectivity part is obsolete and not recommended for new automotive designs. The Harwin M20-9761246 is active but applications are not specified in the provided data. Confirm application suitability with the connector manufacturer before design implementation.

Q: What is the significance of the contact finish differences?

A: The Molex part features gold-plated mating contacts (30.0µin thickness) with tin-plated posts. The TE Connectivity part also uses gold mating contacts but tin-lead posts. The Harwin part uses tin finish on both mating and post contacts. Contact finish affects corrosion resistance, contact resistance, and solderability. Verify compatibility with mating connector specifications and environmental exposure conditions.

Q: Can the Harwin cuttable connector type substitute for the Molex breakaway type?

A: Both connector types support the same 24-position, 2-row configuration with identical pitch and row spacing. The cuttable design allows individual position separation, while the breakaway design provides pre-defined breakaway points. Mechanical compatibility depends on application requirements for connector segmentation and assembly methods.

Q: What compliance certifications apply to each part?

A: The Molex 0010897243 and Harwin M20-9761246 are ROHS3 compliant. The TE Connectivity 4-102977-0-12 is RoHS non-compliant. All three parts meet UL94 V-0 flammability requirements and carry MSL 1 (unlimited) moisture sensitivity classification. Confirm compliance requirements for your specific application before part selection.
