Equivalent & Substitute Parts for Molex 0010894203

Part Overview

The Molex 0010894203 is an active rectangular connector header designed for through-hole, right-angle mounting applications. This 20-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-board and cable interconnection requirements across automotive, general purpose, lighting, medical, and telecommunications applications. Alternative parts may be required due to inventory constraints, packaging preferences, or specific mechanical requirements in system design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010894203 is determined by strict alignment of the following critical parameters:

• Connector pitch: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Position count and row configuration: 20 positions in 2 rows
• Mounting orientation: Through-hole, right-angle configuration
• Contact type: Male pin headers
• Termination method: Solder termination
• Insulation material: Polyester, glass-filled construction
• Flammability compliance: UL94 V-0 rating
• RoHS compliance: ROHS3 Compliant status

The Samtec Inc. MTSW-110-09-L-D-430-RA meets all critical substitution criteria. Variations in contact length, contact material composition, and packaging format do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010894203 and Samtec MTSW-110-09-L-D-430-RA are active products with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Contact length requirements: The Samtec part features extended mating contact length (0.430" versus 0.320"), which may be advantageous in applications requiring deeper mating depth or higher contact engagement. The Molex part provides shorter post length (0.110" versus 0.090"), which may be preferred in space-constrained PCB designs.

Packaging format: The Molex part is supplied in tube packaging, while the Samtec part is supplied in bulk packaging. Procurement and handling workflows should account for these packaging differences.

Contact material: The Molex part uses copper alloy contacts, while the Samtec part uses phosphor bronze. Both materials are suitable for standard signal and power applications within the specified electrical ratings.

Both parts maintain equivalent insulation height (approximately 0.220"), ensuring compatible mating with standard 0.100" pitch receptacles and connectors.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MTSW-110-09-L-D-430-RA directly replace the Molex 0010894203 in existing designs?

A: Yes, for standard board-to-board applications. Both connectors share identical pitch (0.100"), position count (20), row configuration (2 rows), and row spacing (0.100"). The primary design consideration is contact length: the Samtec part has longer mating contacts (0.430" versus 0.320"), which may require verification in applications with tight mating depth tolerances.

Q: What is the difference between "Breakaway" and "Cuttable" connector types?

A: Both designations indicate the connector can be separated into individual positions or smaller groups. The specific mechanical implementation may differ between manufacturers, but both provide equivalent functionality for applications requiring partial connector use.

Q: Are there electrical rating differences between these parts?

A: The Samtec part specifies an operating temperature range of -55°C to 125°C and a current rating of 3A. The Molex part does not provide these specifications in the available data. For applications requiring confirmed electrical ratings, consult the respective manufacturer datasheets.

Q: Does packaging format affect connector performance?

A: No. Tube and bulk packaging are handling and storage formats only. Both packaging types preserve connector integrity and performance characteristics when stored under standard conditions (MSL 1 - Unlimited moisture sensitivity level).

Q: Are both parts suitable for automotive applications?

A: Yes. Both connectors are listed for automotive applications and maintain ROHS3 compliance and UL94 V-0 flammability certification required in automotive environments.
