MDF27-1822PCF Equivalent & Substitute Parts

Part Overview

The MDF27-1822PCF is a crimp contact terminal manufactured by Hirose Electric Co Ltd, designed for wire-to-board applications with 18-22 AWG wire gauge compatibility. This component features tin plating on brass contacts and is classified as a through-board, locking terminal. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF27-1822PCF is determined by the following critical parameters:

• Wire Gauge Compatibility: The substitute must accommodate wire gauges within or overlapping the 18-22 AWG range
• Contact Material & Finish: Brass with tin plating ensures equivalent electrical and corrosion resistance properties
• Terminal Type: Wire-to-board configuration with appropriate contact geometry
• Insulation Diameter Range: Must accept the specified insulation diameter range or a compatible subset
• Compliance Standards: RoHS compliance and MSL rating must meet or exceed the original specification

The Molex 1722490200 qualifies as a substitute based on these parameters. While its wire gauge range (18-20 AWG) is narrower than the original specification, it falls entirely within the MDF27-1822PCF operating range and maintains all other critical electrical and mechanical characteristics.

Engineering Selection Recommendations

The Molex 1722490200 is the designated manufacturer-recommended substitute for the obsolete MDF27-1822PCF. Selection of this alternative is supported by the following factors:

• Active Product Status: The Molex component is currently in active production, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both components maintain MSL 1 rating and RoHS compliance, with the Molex part meeting the more stringent ROHS3 standard
• Electrical Equivalence: Identical contact material (brass) and finish (tin) provide equivalent electrical performance and corrosion resistance
• Wire Gauge Coverage: The 18-20 AWG range of the substitute fully encompasses the most common wire gauges within the original 18-22 AWG specification
• Mechanical Compatibility: Wire-to-board terminal configuration with overlapping insulation diameter range supports direct functional replacement in most applications

Frequently Asked Questions (FAQ)

Q: Can the Molex 1722490200 directly replace the MDF27-1822PCF in all applications?

A: The Molex substitute is functionally equivalent for applications using 18-20 AWG wire gauges. Applications specifically requiring 20-22 AWG wire gauge support should be evaluated for compatibility with the narrower gauge range of the substitute.

Q: What is the significance of the insulation diameter difference between the two parts?

A: The MDF27-1822PCF accepts insulation diameters from 0.083" to 0.114" (2.11mm to 2.90mm), while the Molex 1722490200 accepts 0.071" to 0.083" (1.80mm to 2.11mm). The overlap at 0.083" (2.11mm) ensures compatibility for wire gauges within the shared range. Larger insulation diameters associated with 22 AWG wire may not be accommodated by the substitute.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both components meet RoHS requirements and maintain MSL 1 rating. The Molex part carries ROHS3 compliance, which represents a more recent regulatory standard. Both components are classified under the same HTSUS code (8536.90.4000) and ECCN (EAR99).

Q: What packaging format is available for the substitute part?

A: The Molex 1722490200 is supplied in Cut Tape (CT) packaging, with 302,040 pieces available in current inventory.
