Equivalent & Substitute Parts for 68000-203H

Part Overview

The 68000-203H is a rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® II series. This is a through-hole, vertical-mount connector with 3 positions at 0.100" (2.54mm) pitch, designed for board-to-board applications. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 68000-203H is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 3 positions in a single row
• Connector Configuration: Header type with male pins, through-hole mounting, solder termination
• Electrical Performance: Push-pull fastening, gold-plated mating contacts, 3A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating, operating temperature range -65°C to 125°C
• Physical Compatibility: Board-to-board style, unshrouded design

The Molex 0022284033 (KK254 series) meets these substitution criteria through matching pitch, position count, connector type, mounting method, and termination approach. Both parts maintain equivalent electrical and mechanical interfaces for standard PCB applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022284033 serves as the primary substitute for the obsolete 68000-203H. Key selection factors include:

Product Status: The 68000-203H is obsolete, while the 0022284033 maintains active production status with 24,275 pieces in stock, ensuring long-term availability and supply chain continuity.

Compliance Posture: The 0022284033 is ROHS3 compliant and REACH unaffected, whereas the 68000-203H is RoHS non-compliant. For new designs or applications subject to regulatory requirements, the Molex part provides compliance alignment.

Physical and Electrical Equivalence: Both connectors share identical pitch (0.100"), position count (3), mounting method (through-hole), and termination (solder). Contact finish specifications match at 15.0µin (0.38µm) gold plating on mating surfaces.

Mechanical Compatibility: The Molex KK254 series header maintains push-pull fastening and unshrouded board-to-board configuration, supporting direct PCB layout compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284033 be used as a direct replacement for the 68000-203H in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (3), mounting type (through-hole), and termination method (solder). PCB footprints and mating interface dimensions are compatible. The Molex part includes a breakaway feature, which does not affect standard header functionality.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and insulation material specification (not provided for 68000-203H vs. polyamide nylon glass-filled for 0022284033). Contact geometry and electrical ratings remain equivalent.

Q: Are there any mating interface incompatibilities?

A: No. Both connectors use 0.100" (2.54mm) pitch male pin headers with identical contact finish specifications. Standard 2.54mm pitch receptacles mate with both parts without modification.

Q: What is the significance of the breakaway feature on the Molex part?

A: The breakaway feature allows individual pins to be separated from the header strip if required for specific applications. This does not affect standard board-to-board mating and provides additional design flexibility.

Q: Should RoHS compliance be considered when selecting between these parts?

A: RoHS compliance is a regulatory requirement for many applications, particularly in consumer electronics and EU markets. The Molex 0022284033 (ROHS3 compliant) is recommended for new designs subject to RoHS directives. Legacy systems using the 68000-203H may continue operation without modification.

Q: Is the current rating equivalent between both parts?

A: The 68000-203H specifies 3A per contact. The 0022284033 does not provide a current rating in the available specifications. For applications requiring confirmed current capacity, contact the manufacturer for detailed electrical performance data.
