Molex 0533250960 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0533250960 is a shrouded right-angle header connector with 9 positions at 2.00mm pitch, designed for through-hole board-to-cable/wire applications. This connector features kinked pin solder termination and is classified as obsolete. Due to its obsolete status and limited ongoing availability, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0533250960 is determined by the following critical parameters:

• Pitch and Position Count: 0.079" (2.00mm) pitch with 9 positions in a single row
• Connector Orientation: Right-angle through-hole mounting
• Contact Configuration: Male pin header for board-to-cable/wire connection
• Shrouding Design: Shrouded construction for polarization and mechanical protection
• Electrical Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Termination Compatibility: Solder-based termination for PCB assembly

The TE Connectivity AMP Connectors 440055-9 meets these core substitution criteria. While minor variations exist in shrouding wall count (3 wall vs. 4 wall), contact dimensions, and termination method (press-fit/solder vs. kinked pin/solder), the electrical and mechanical interface compatibility remains within acceptable engineering tolerances for equivalent functionality.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 440055-9 is the primary equivalent substitute for the obsolete Molex 0533250960. Selection is justified on the following basis:

• Product Status Alignment: The TE Connectivity part is active and in production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance, meeting equivalent environmental and safety standards.
• Functional Equivalence: Matching pitch (2.00mm), position count (9), connector type (header), contact type (male pin), and mounting configuration (through-hole right-angle) ensure direct functional compatibility.
• Electrical Specifications: The TE Connectivity substitute provides defined electrical ratings (3A current, 250V voltage) and operating temperature range (-25°C ~ 85°C), establishing clear performance boundaries for circuit design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 440055-9 be used as a direct replacement for the Molex 0533250960 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (9), mounting type (through-hole right-angle), and contact configuration (male pin header). The core electrical and mechanical interface is compatible. Minor physical differences in shrouding wall count and insulation material do not affect functional substitution.

Q: What is the significance of the shrouding difference (4 wall vs. 3 wall)?

A: Shrouding wall count affects mechanical robustness and polarization features. The 4-wall design of the Molex part provides additional structural support, while the 3-wall design of the TE Connectivity part maintains equivalent polarization and protection. Both designs are suitable for board-to-cable/wire applications.

Q: Are there any termination method differences between these parts?

A: Yes. The Molex 0533250960 uses kinked pin solder termination, while the TE Connectivity 440055-9 uses press-fit and solder termination. Both methods are compatible with standard PCB assembly processes. Press-fit termination may offer improved mechanical retention during assembly.

Q: What are the electrical performance differences?

A: The TE Connectivity 440055-9 specifies 3A current rating and 250V voltage rating with an operating temperature range of -25°C ~ 85°C. The Molex part does not provide these specifications. For applications requiring defined electrical performance parameters, the TE Connectivity part establishes clear operational limits.

Q: Is the insulation material difference (PBT glass-filled vs. thermoplastic) significant?

A: Both materials meet UL94 V-0 flammability requirements. PBT glass-filled insulation offers enhanced mechanical strength and thermal stability, while thermoplastic insulation provides adequate performance for general-purpose applications. Material selection depends on specific environmental and mechanical stress requirements of the application.

Q: What is the inventory status for these parts?

A: The Molex 0533250960 is obsolete with 1074 pieces in stock. The TE Connectivity 440055-9 is active with 14168 pieces in stock, providing superior long-term availability and procurement reliability.
