Molex 0010894307 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010894307 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This unshrouded, breakaway header features 30 positions across 2 rows with 0.100" (2.54mm) pitch spacing and gold-plated mating contacts. The component is widely used in automotive, general purpose, lighting, medical, and telecommunications applications where reliable solder termination and push-pull fastening are required. Substitute parts may be necessary due to inventory constraints, end-of-life considerations, or specific application requirements that align with the electrical and mechanical parameters of this connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010894307 is determined by strict alignment with the following critical parameters:

• Pitch and Spacing: Mating pitch of 0.100" (2.54mm) and row spacing of 0.100" (2.54mm) are mandatory for mechanical and electrical compatibility
• Connector Type and Contact Type: Header configuration with male pin contacts and breakaway design
• Mounting and Termination: Through-hole, right-angle mounting with solder termination
• Contact Finish: Gold-plated mating contacts for reliable signal transmission
• Fastening Mechanism: Push-pull fastening type for secure mating
• Insulation Material and Flammability: UL94 V-0 rated insulation for safety compliance

The TE Connectivity AMP Connectors part 4-102979-0 is identified as a manufacturer-recommended substitute. While this part operates within the same connector family and shares core electrical and mechanical parameters, specific differences exist in position count, insulation material composition, and compliance certifications that must be evaluated for the intended application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - Molex 0010894307: This connector remains the preferred choice for new designs and applications requiring ROHS3 compliance. The part is active-status with confirmed inventory availability and meets all specified flammability and environmental standards.

Substitute Part - TE Connectivity 4-102979-0: This part is suitable as a substitute only when the following conditions are met:

• The application does not mandate ROHS3 compliance, as this substitute is RoHS non-compliant
• The higher position count (80 vs. 30) does not create mechanical or electrical conflicts in the target application
• The thermoplastic insulation material is compatible with the operating environment
• The tin-lead post finish is acceptable for the solder termination process

The TE Connectivity part provides an active-status alternative with documented operating temperature range (-65°C ~ 105°C) and current rating (3A), parameters not specified for the Molex original. However, the compliance difference is a critical consideration for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-102979-0 be used as a direct replacement for the Molex 0010894307?

A: The TE Connectivity part shares the same mating pitch (0.100"), row spacing (0.100"), connector type (header, breakaway), mounting style (through-hole, right-angle), and fastening mechanism (push-pull). However, it differs in position count (80 vs. 30), insulation material (thermoplastic vs. polyester glass-filled), and RoHS compliance status. Substitution is possible only if these differences are compatible with the target application requirements.

Q: What are the critical parameters that determine substitution compatibility?

A: The following parameters must remain constant for substitution: mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), connector type (header, breakaway), contact type (male pin), mounting type (through-hole, right-angle), termination method (solder), fastening type (push-pull), and contact finish (gold mating surface). Variations in position count, insulation material, and compliance certifications may be acceptable depending on application-specific constraints.

Q: Does the higher position count of the TE Connectivity part affect compatibility?

A: The TE Connectivity 4-102979-0 provides 80 positions compared to the Molex original's 30 positions. This difference does not affect the electrical or mechanical compatibility of individual mating pairs, as the pitch and spacing remain identical. However, the physical footprint and board layout requirements will differ significantly. Substitution is valid only if the application can accommodate the larger connector assembly or if only a subset of positions is utilized.

Q: What is the significance of the insulation material difference?

A: The Molex part uses polyester glass-filled insulation, while the TE Connectivity substitute uses thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements. The choice between these materials may affect mechanical properties, temperature stability, and chemical resistance in specific operating environments. Application-specific environmental conditions should be evaluated before substitution.

Q: Why is RoHS compliance status important for this substitution?

A: The Molex 0010894307 is ROHS3 compliant, while the TE Connectivity 4-102979-0 is RoHS non-compliant. For applications subject to RoHS regulations (particularly in automotive, medical, and telecommunications sectors), the compliance status is a mandatory selection criterion. The Molex part is required for regulated applications; the TE Connectivity part is suitable only for applications without RoHS mandates.

Q: Are there differences in contact finish specifications between these parts?

A: Both parts feature gold-plated mating contacts with identical finish thickness (30.0µin / 0.76µm). The post finish differs: the Molex part uses tin, while the TE Connectivity part uses tin-lead. This difference may affect solder joint formation and long-term reliability in specific thermal cycling or vibration environments. Solder process parameters may require adjustment when switching between these finishes.
