Molex 0009624049 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0009624049 is a 4-position receptacle connector with 0.156" (3.96mm) pitch, designed for through-hole PCB mounting with solder termination. This connector is part of the KK396 and 2145 series and is classified as obsolete. The part features gold-plated mating contacts, tin-plated posts, and board hooks for mechanical retention. Due to its obsolete status, identifying active equivalent parts is essential for ongoing production and maintenance applications requiring compatible rectangular connectors in automotive, medical, telecommunications, and general-purpose circuits.

Substitute Part Grouping Explanation

Substitution of the Molex 0009624049 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 4 positions at 0.156" (3.96mm) mating pitch
• Mounting & Termination: Through-hole PCB mounting with solder termination
• Electrical Ratings: 5A current rating and 600V voltage rating
• Contact Finish: Gold-plated mating surface with tin-plated posts
• Mechanical Features: Board hooks for retention and locking ramp fastening
• Environmental Range: -40°C to 105°C operating temperature

The substitute part Molex 0009485045 meets all these criteria and is classified as active, making it a direct functional equivalent for the obsolete 0009624049.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0009485045 is the direct active equivalent for the obsolete Molex 0009624049. Both parts are ROHS3 compliant and share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, current and voltage ratings, and operating temperature range.

The substitute part offers two advantages over the original:

1. Active Product Status: The 0009485045 is currently in active production, ensuring long-term availability and supply chain continuity.

2. Enhanced Flammability Rating: The substitute achieves UL94 V-0 classification compared to the original's UL94 V-2, providing superior material flammability performance.

The insulation material differs (polyester versus polyamide/nylon) and the insulation color is natural rather than white. These differences do not affect electrical performance, mechanical compatibility, or functional equivalence in circuit applications. Both parts maintain identical contact geometry, pitch spacing, and termination characteristics required for PCB assembly and mating with corresponding plug connectors.

Frequently Asked Questions (FAQ)

Q: Can the 0009485045 directly replace the 0009624049 in existing designs?

A: Yes. The 0009485045 is electrically and mechanically equivalent to the 0009624049 across all functional parameters. Both connectors have identical pitch (0.156"), position count (4), current rating (5A), voltage rating (600V), and operating temperature range (-40°C to 105°C). PCB layouts and mating connector specifications require no modification.

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

A: The original 0009624049 uses polyamide (PA) or nylon insulation, while the substitute 0009485045 uses polyester insulation. Both materials meet the same electrical performance requirements and are suitable for the specified operating temperature range and voltage rating. The material change does not affect connector function or compatibility.

Q: Why does the substitute have a better flammability rating?

A: The 0009485045 achieves UL94 V-0 classification while the 0009624049 is rated UL94 V-2. This reflects improvements in material formulation and manufacturing standards. The V-0 rating indicates superior flame resistance and is a benefit when used in applications with enhanced safety requirements.

Q: Are there packaging differences between these parts?

A: The original 0009624049 packaging is not specified in the data. The substitute 0009485045 is supplied in tray packaging. Confirm packaging requirements with your procurement or assembly team to ensure compatibility with your production processes.

Q: What is the inventory status for these parts?

A: The 0009624049 (obsolete) has 1092 pieces in stock. The 0009485045 (active) has 1176 pieces in stock. For long-term production planning, the active part is the recommended choice due to its ongoing availability.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0009624049 and 0009485045 are ROHS3 compliant and suitable for applications requiring RoHS certification.
