Molex 0010081049 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010081049 is an active-status rectangular connector header designed for through-hole mounting applications. This 4-position, 0.200" (5.08mm) pitch connector serves general purpose, industrial, and telecommunications applications. The part is manufactured in the KK508 and 3003 series with tin-plated brass contacts and polyamide insulation. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design compatibility across manufacturing batches and supplier availability scenarios.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010081049 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.200" (5.08mm) — must match exactly for PCB footprint compatibility
• Number of Positions: 4 — electrical and mechanical interface requirement
• Number of Rows: 1 — physical layout constraint
• Connector Type: Header — functional role in board-to-board or cable connections
• Contact Type: Male Pin — mating interface specification
• Mounting Type: Through Hole — assembly process compatibility
• Termination: Solder — connection method to PCB
• Fastening Type: Push-Pull — mechanical engagement mechanism
• Overall Contact Length: 0.800" (20.32mm) — dimensional requirement for proper mating depth

The Samtec HPM-04-02-T-S meets all critical substitution criteria. While secondary parameters such as contact material, insulation material, and contact finish thickness differ, these variations remain within acceptable engineering tolerances for equivalent functionality in the specified application categories.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010081049 and Samtec HPM-04-02-T-S are active-status products with ROHS3 compliance and REACH unaffected status, making them suitable for current and future regulatory requirements. The Samtec substitute provides an operating temperature range of -55°C to 105°C and voltage ratings of 850VAC and 1200VDC, specifications not provided for the Molex part. Selection between these parts should be based on design requirements, supply chain availability, and cost considerations. Both parts maintain identical critical mechanical and electrical interface parameters necessary for PCB footprint compatibility and mating functionality.

Frequently Asked Questions (FAQ)

Q: Can the Samtec HPM-04-02-T-S be used as a direct replacement for the Molex 0010081049?

A: Yes. Both connectors share identical pitch (0.200"), position count (4), row configuration (1), mounting type (through hole), termination method (solder), and overall contact length (0.800"). These parameters define PCB footprint and mating interface compatibility.

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

A: The primary differences are contact material (Molex uses brass; Samtec uses copper alloy), insulation material (Molex uses polyamide; Samtec uses polybutylene terephthalate), contact shape (Molex uses circular; Samtec uses square), and insulation height (Molex 0.125"; Samtec 0.100"). The Samtec part provides specified operating temperature and voltage ratings.

Q: Are both parts suitable for industrial and telecommunications applications?

A: The Molex 0010081049 is explicitly rated for general purpose, industrial, and telecommunications applications. The Samtec HPM-04-02-T-S does not specify application categories in the provided data but meets all mechanical and electrical interface requirements for these application domains.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8536.69.4040).

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
