Molex 0022283345 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022283345 is a vertical rectangular connector header designed for through-hole mounting with 34 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement. The KK254 series connector provides board-to-board or cable connectivity with shrouded single-wall construction and kinked pin solder termination. Due to its obsolete status, sourcing active alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the Molex 0022283345 is determined by strict equivalence across the following critical parameters:

• Connector pitch and position count: 0.100" (2.54mm) spacing with 34 positions
• Connector type and contact configuration: Header with male pins, single row, breakaway design
• Mounting and termination method: Through-hole mounting with kinked pin solder termination
• Shrouding configuration: Shrouded single-wall construction
• Contact finish specification: Gold-plated mating surface with tin-plated post
• Insulation material and flammability: Polyamide nylon glass-filled material rated UL94 V-0
• Environmental compliance: RoHS3 compliance and MSL 1 rating

The Molex 0022280345 meets all these substitution criteria as an active product within the KK254 series family, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280345 is the recommended substitute for the obsolete Molex 0022283345. Both connectors share identical mechanical and electrical interface specifications, ensuring direct compatibility in existing designs. The substitute part is classified as active product status, providing assured long-term availability and supply chain continuity.

The substitute part carries RoHS compliance certification and maintains the same environmental rating (MSL 1, Unlimited). Both components are rated for identical application domains: automotive, general purpose, medical, and telecommunications environments. The substitute provides documented operating temperature range (-40°C to 105°C) and voltage rating (600VAC/DC) specifications, offering enhanced technical documentation compared to the original part.

The fastening mechanism differs between the two parts: the original uses push-pull fastening while the substitute employs friction lock fastening. This distinction does not affect mating interface compatibility but should be evaluated within the context of the specific application's connector retention requirements.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0022283345 and 0022280345 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (34), contact geometry, insulation height, and mounting configuration. Through-hole PCB footprints are compatible between the two parts.

Q: What is the primary reason for substitution?

A: The Molex 0022283345 is classified as obsolete. The Molex 0022280345 is an active product within the same KK254 series, ensuring ongoing availability and manufacturing support.

Q: Do the connectors have the same contact finish specifications?

A: Yes. Both parts feature gold-plated mating contacts (with differing thickness specifications: 30.0µin versus 3.00µin) and tin-plated posts at 100.0µin thickness. The mating surface finish material is identical.

Q: What is the difference in fastening type between these parts?

A: The original part uses push-pull fastening, while the substitute uses friction lock fastening. Both methods provide secure mating but operate through different mechanical principles. Application-specific connector retention requirements should be evaluated.

Q: Are both parts RoHS compliant?

A: Yes. The original part is ROHS3 compliant, and the substitute is RoHS compliant. Both meet environmental regulatory requirements for restricted substance use.

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

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

Q: Can the substitute part be used in automotive applications?

A: Yes. Both connectors are specified for automotive applications, along with general purpose, medical, and telecommunications use cases.
