Molex 0015445146 Equivalent & Substitute Parts

Part Overview

The Molex 0015445146 is a 46-position receptacle connector featuring 0.100" (2.54mm) pitch through-hole mounting with gold-plated mating contacts. This connector is designed for board-to-board or cable applications and is actively manufactured. The part operates across a wide temperature range of -40°C to 125°C and is rated for 2.5A at 500VAC, making it suitable for automotive, medical, telecommunications, and general-purpose applications. Identifying equivalent substitute parts is necessary when the primary part is unavailable or when alternative sourcing options are required for procurement optimization.

Substitute Part Grouping Explanation

Substitution of the Molex 0015445146 is determined by the following critical parameters:

Mandatory Matching Parameters:

Number of positions: 46
Pitch - mating: 0.100" (2.54mm)
Number of rows: 2
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through hole
Contact finish - mating: Gold
Termination: Solder

Allowable Variation Parameters:

Connector type: Receptacle or Header (both support board-to-board connectivity)
Current rating: Minimum 2.5A (substitute may exceed this specification)
Voltage rating: Minimum 500VAC (substitute may exceed this specification)
Operating temperature: Minimum -40°C to 125°C range (substitute may have narrower range if it encompasses the required operating window)
Insulation material: May vary (LCP or Polyester acceptable)
Contact finish thickness: May vary (Flash or plated thickness acceptable)

The Sullins Connector Solutions PPPC232LFBN-RC qualifies as a substitute based on these criteria.

Engineering Selection Recommendations

The Sullins Connector Solutions PPPC232LFBN-RC is an active product with ROHS3 compliance and UL94 V-0 flammability rating, matching the regulatory and compliance profile of the Molex 0015445146.

When evaluating this substitute, the following considerations apply based on provided specifications:

The substitute connector exceeds the current rating requirement (3A versus 2.5A). However, the voltage rating of the substitute (250V) is below the primary part specification (500VAC). The operating temperature range of the substitute (-40°C to 105°C) is narrower than the primary part (-40°C to 125°C), excluding operation above 105°C.

Selection of the Sullins substitute is appropriate only when the application requirements do not exceed 250VAC and do not require operation above 105°C. Both parts share identical mechanical dimensions, pitch, row configuration, and gold-plated mating contacts, ensuring physical and electrical compatibility within these voltage and temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can the Sullins PPPC232LFBN-RC directly replace the Molex 0015445146 in all applications?

A: No. While both connectors share identical mechanical and pitch specifications, the Sullins substitute has a lower voltage rating (250V versus 500VAC) and a narrower operating temperature range (-40°C to 105°C versus -40°C to 125°C). Substitution is valid only when application requirements remain within these electrical and thermal limits.

Q: What is the difference between a receptacle and header connector in this context?

A: The Molex part is a receptacle (socket), while the Sullins part is a header (pin). Both are designed for board-to-board connections and are mechanically compatible at the 0.100" (2.54mm) pitch. The functional difference lies in the contact gender, not in substitution capability for this application.

Q: Are the insulation materials interchangeable?

A: The Molex part uses glass-filled Liquid Crystal Polymer (LCP), while the Sullins part uses Polyester. Both materials are UL94 V-0 rated. Material selection depends on specific application requirements such as chemical resistance, dimensional stability, and thermal properties, which are not specified in the provided parameters.

Q: What is the significance of the contact finish specifications?

A: Both parts feature gold-plated mating contacts. The Molex part specifies 30.0µin (0.76µm) thickness, while the Sullins part specifies flash plating. Both finishes provide corrosion resistance and reliable electrical contact. Flash plating is thinner but adequate for standard applications.

Q: Can I use the Sullins connector in automotive applications?

A: The Molex part explicitly lists automotive applications. The Sullins part does not specify applications in the provided data. Automotive use requires validation against specific automotive standards and environmental requirements not included in the provided parameters.
