Molex 0010894247 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010894247 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This unshrouded, 24-position header with 2.54mm pitch and male pin contacts serves general purpose, automotive, lighting, medical, and telecommunications applications. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010894247 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly
• Contact Type: Male Pin — must match exactly
• Mounting Type: Through Hole, Right Angle — must match exactly
• Termination: Solder — must match exactly
• Connector Type: Header, Breakaway — must match exactly
• Number of Rows: 2 — must match exactly
• Row Spacing - Mating: 0.100" (2.54mm) — must match exactly
• Contact Finish - Mating: Gold — must match exactly
• Material Flammability Rating: UL94 V-0 — must match exactly

The TE Connectivity AMP Connectors part 4-102979-0 shares these critical parameters. However, the number of positions differs (80 positions versus 24 positions), which affects physical footprint and application scope. This difference must be evaluated against specific board layout and connector requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 4-102979-0 shares critical electrical and mechanical parameters with the Molex 0010894247, including pitch, contact type, mounting configuration, and flammability rating. Both parts maintain active product status.

Key considerations for selection:

Position Count Difference: The TE Connectivity part provides 80 positions compared to 24 positions in the Molex part. This difference requires evaluation against specific board layout constraints and connector requirements.

Compliance Differences: The Molex 0010894247 is ROHS3 compliant, while the TE Connectivity 4-102979-0 is RoHS non-compliant. Applications subject to RoHS requirements must use the Molex part or identify alternative compliant substitutes.

Contact Finish - Post: The Molex part uses Tin finish, while the TE Connectivity part uses Tin-Lead finish. This difference may affect soldering characteristics and environmental exposure considerations.

Insulation Material: The Molex part uses Polyester, Glass Filled insulation, while the TE Connectivity part uses Thermoplastic insulation. Material selection affects mechanical and thermal properties.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-102979-0 directly replace the Molex 0010894247?

A: Direct replacement depends on application requirements. Both parts share identical pitch (2.54mm), contact type (male pin), mounting type (through hole, right angle), and flammability rating (UL94 V-0). However, the 80-position TE Connectivity part differs from the 24-position Molex part in physical footprint and connector capacity. Board layout compatibility must be verified before substitution.

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

A: Substitution compatibility is determined by: mating pitch (0.100" / 2.54mm), contact type (male pin), mounting type (through hole, right angle), termination method (solder), connector type (header, breakaway), number of rows (2), row spacing (0.100" / 2.54mm), mating contact finish (gold), and material flammability rating (UL94 V-0). Deviations in any of these parameters indicate incompatibility.

Q: Does the TE Connectivity part meet RoHS requirements?

A: No. The TE Connectivity 4-102979-0 is RoHS non-compliant, while the Molex 0010894247 is ROHS3 compliant. Applications requiring RoHS compliance must use the Molex part or identify alternative RoHS-compliant substitutes.

Q: What is the difference in insulation material between these parts?

A: The Molex 0010894247 uses Polyester, Glass Filled insulation, while the TE Connectivity 4-102979-0 uses Thermoplastic insulation. These materials differ in mechanical strength, thermal properties, and environmental resistance. Application-specific requirements determine which material is appropriate.

Q: Are the contact finishes compatible?

A: Both parts use gold mating contact finish with identical thickness (30.0µin / 0.76µm). The post contact finish differs: Molex uses Tin, while TE Connectivity uses Tin-Lead. This difference affects soldering characteristics and may influence thermal cycling performance.

Q: What is the position count difference, and does it matter?

A: The Molex part provides 24 positions in a 2-row configuration, while the TE Connectivity part provides 80 positions in a 2-row configuration. The position count directly affects physical connector size and board footprint. Substitution requires verification that the larger TE Connectivity connector fits the available board space and meets application requirements.
