Molex 0010894143 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0010894143 is a through-hole, right-angle rectangular connector header with 14 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is designed for board-to-board or cable applications in automotive, general purpose, lighting, medical, and telecommunications environments. The part is currently active in production with 763 units in stock. Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements allow for functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010894143 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Header type with breakaway capability, male pin contact type
• Position Count & Arrangement: Exactly 14 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole, right-angle mounting with solder termination capability
• Fastening Mechanism: Push-pull fastening type
• Contact Materials & Finish: Gold-plated mating contacts and tin-plated posts
• Insulation Properties: UL94 V-0 flammability rating and MSL 1 classification

The substitute part TE Connectivity AMP Connectors 5-146311-7 meets all these critical parameters, enabling direct functional substitution in applications where the Molex part is specified.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5-146311-7 is a valid substitute for the Molex 0010894143 based on matching electrical and mechanical specifications. Both parts share identical pitch, position count, row configuration, contact type, and fastening mechanism. Both are UL94 V-0 rated and MSL 1 classified, meeting the same environmental and reliability standards.

The primary consideration is product status: the Molex part is currently active, while the TE Connectivity part is obsolete. Selection should prioritize the active Molex part for new designs and long-term supply assurance. The TE Connectivity substitute is appropriate for legacy system maintenance, repair applications, or situations where existing inventory must be utilized. The TE Connectivity part offers additional press-fit termination capability alongside solder termination, providing design flexibility in certain applications.

Minor dimensional variations exist in contact length (0.002" difference) and insulation height (0.018" difference), which remain within acceptable tolerances for standard board-to-board connector applications. The insulation material difference (polyester versus thermoplastic, both glass-filled) does not affect functional compatibility given the identical flammability rating and environmental classification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146311-7 be used as a direct replacement for the Molex 0010894143 in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (14), row configuration (2 rows), contact type (male pin), mounting style (through-hole right-angle), and fastening mechanism (push-pull). Electrical and mechanical compatibility is confirmed across all critical parameters.

Q: What are the key differences between these two parts?

A: The Molex part is currently active in production, while the TE Connectivity part is obsolete. The TE Connectivity part offers dual termination capability (press-fit and solder) compared to solder-only for the Molex part. Insulation material differs (polyester versus thermoplastic), and minor dimensional variations exist in contact length and insulation height, all within acceptable tolerances.

Q: Are there any compliance or certification differences?

A: Both parts are UL94 V-0 rated and MSL 1 classified. The Molex part is ROHS3 compliant, while the TE Connectivity part is RoHS compliant. Both share the same ECCN (EAR99) and HTSUS code (8536.69.4040), indicating equivalent regulatory treatment.

Q: Which part should be specified for new product designs?

A: The Molex 0010894143 should be specified for new designs due to its active production status and assured long-term availability. The TE Connectivity 5-146311-7 is appropriate for legacy system support and repair applications only.

Q: Are the dimensional differences significant for PCB layout?

A: No. The contact length difference (0.002") and insulation height difference (0.018") are minor and do not affect standard board-to-board connector mounting or mating interface design. Both parts are compatible with the same PCB footprint and mating connector designs.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, supply chain and obsolescence considerations should guide part selection. The active Molex part is preferred for production assemblies, while the obsolete TE Connectivity part may be used for field repairs or legacy system maintenance where existing inventory is available.
