Molex 0022283258 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0022283258 is a vertical rectangular connector header designed for through-hole mounting with 25 positions at 0.100" (2.54mm) pitch. This connector 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 push-pull fastening. Locating functionally equivalent active-status alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022283258 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, breakaway design
• Position Count & Pitch: 25 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Shrouding & Mechanical Form: Single-wall shrouded construction
• Contact Geometry: 0.295" (7.49mm) mating contact length, square contact shape
• Material & Compliance: Polyamide insulation, UL94 V-0 flammability rating, RoHS compliance

The Molex 0022280258 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: the 0022280258 is active, whereas the 0022283258 is obsolete. Secondary differences in fastening mechanism (friction lock vs. push-pull) and contact finish thickness do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022280258 is the recommended substitute for the obsolete Molex 0022283258. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 25-position configuration, 0.100" (2.54mm) pitch, through-hole solder termination, and single-wall shrouded construction.

The 0022280258 offers the advantage of active product status, ensuring ongoing manufacturer support and supply availability. Both parts carry UL94 V-0 flammability certification and RoHS compliance, meeting regulatory requirements for automotive, medical, and telecommunications applications.

The fastening mechanism differs between the two parts (push-pull vs. friction lock); however, this distinction does not affect functional interchangeability in standard board-level applications. The contact finish thickness on the mating surface is reduced in the substitute part (3.00µin vs. 30.0µin), which remains within acceptable engineering tolerances for general-purpose connector applications.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0022283258 and 0022280258 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (25), contact geometry (0.295" mating length, square shape), and mounting configuration (through-hole, single-wall shrouded). Physical form factor compatibility is confirmed.

Q: What is the impact of the fastening type difference (push-pull vs. friction lock)?

A: The fastening mechanism affects mating/unmating force and retention method but does not alter electrical performance or physical fit. Selection between push-pull and friction lock depends on application-specific requirements for connector retention and ease of disconnection.

Q: Does the reduced contact finish thickness on the substitute part affect performance?

A: The mating contact finish thickness is reduced from 30.0µin to 3.00µin on the 0022280258. Both thicknesses provide adequate gold plating for corrosion resistance and electrical conductivity in standard applications. Thickness selection depends on environmental exposure and contact cycling requirements.

Q: Are both parts RoHS compliant?

A: The 0022283258 is ROHS3 compliant. The 0022280258 is RoHS compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What is the operating temperature range for these connectors?

A: The 0022283258 does not specify an operating temperature range. The 0022280258 operates from -40°C to 105°C. For applications requiring temperature specification, the 0022280258 provides documented thermal performance limits.

Q: Can the 0022280258 be used as a direct replacement in existing designs?

A: Yes, provided the application does not depend on the specific fastening mechanism of the original push-pull design. Electrical and mechanical compatibility is confirmed across all standard parameters.
