Molex 0022283248 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022283248 is a vertical rectangular connector header designed for through-hole mounting applications. This 24-position, single-row connector operates at 0.100" (2.54mm) pitch and features shrouded design with male pin contacts. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity across automotive, medical, telecommunications, and general-purpose applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022283248 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 24
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Contact Length - Mating: 0.295" (7.49mm)
• Contact Length - Post: 0.120" (3.05mm)
• Overall Contact Length: 0.540" (13.72mm)
• Insulation Height: 0.337" (8.56mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Material: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black

The Molex 0022280248 qualifies as a direct substitute based on full alignment with these parameters. The transition from the obsolete KK254 42225 series to the active KK254 42227 series maintains mechanical and electrical compatibility while providing current product availability and active manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280248 is the manufacturer-recommended substitute for the obsolete Molex 0022283248. Both connectors maintain identical mechanical dimensions, contact geometry, and core electrical specifications required for board-to-board or cable interconnection in 24-position, single-row applications at 2.54mm pitch.

The substitute part is actively manufactured and carries current RoHS compliance certification. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with automotive, medical, telecommunications, and general-purpose applications.

Differences in contact finish thickness on mating surfaces and fastening mechanism (Push-Pull versus Friction Lock) do not affect functional interchangeability in applications where the original part was specified. The substitute provides documented operating temperature range (-40°C to 105°C) and voltage rating (600VAC/DC) that were not specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022280248 be used as a direct replacement for the 0022283248 in existing designs?

A: Yes. Both connectors share identical pitch (2.54mm), position count (24), contact geometry, mounting type (through-hole solder), and insulation specifications. The substitute is the manufacturer-recommended active equivalent.

Q: What is the difference between Push-Pull and Friction Lock fastening types?

A: Push-Pull fastening uses a mechanical latch mechanism for secure mating. Friction Lock relies on contact pressure between mating surfaces. Both provide secure connections; the selection depends on application requirements for mating force and disconnect procedure.

Q: Does the thinner gold plating on the substitute part affect contact reliability?

A: Contact finish thickness is specified by the manufacturer for both parts. The substitute's 3.00µin (0.076µm) gold plating on mating surfaces meets Molex specifications for the KK254 42227 series and maintains contact resistance and corrosion protection within design parameters.

Q: Are both parts RoHS compliant?

A: Yes. The original part is ROHS3 compliant. The substitute is RoHS compliant. Both meet regulatory requirements for restricted substance elimination in electronic components.

Q: What is the significance of the glass-filled nylon specification in the original part?

A: The original part specifies glass-filled polyamide for enhanced mechanical strength and dimensional stability. The substitute uses polyamide nylon without the glass-fill specification. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified applications.

Q: Can I use the 0022280248 in medical device applications?

A: Yes. Both the original and substitute parts are listed for medical applications. The substitute maintains identical electrical and mechanical specifications, UL94 V-0 rating, and MSL 1 classification required for medical device interconnection.

Q: What is the inventory status of these parts?

A: The original 0022283248 is obsolete with 715 pieces in stock. The substitute 0022280248 is active with 980 pieces in stock, providing reliable procurement availability for new designs and production continuity.
