M22-2011905 Equivalent & Substitute Parts

Part Overview

The M22-2011905 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole board-to-board applications with 19 positions at 2.00mm pitch. This connector features male pins with gold-plated mating contacts, phosphor bronze material, and operates across -55°C to 105°C. The part is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the M22-2011905 is determined by the following critical parameters that must remain consistent:

Pitch - Mating: 0.079" (2.00mm) — determines mechanical and electrical compatibility with mating connectors
Connector Type: Header, Cuttable — maintains board-to-board application capability
Contact Type: Male Pin — ensures proper mating interface
Mounting Type: Through Hole — preserves PCB assembly compatibility
Series: M22 — confirms manufacturer ecosystem compatibility
Operating Temperature Range: -55°C ~ 105°C — maintains thermal performance envelope
Current Rating: 1A per Contact — sustains electrical load capacity
Contact Material & Finish: Phosphor Bronze with Gold plating — preserves electrical and corrosion resistance properties

The M22-2012005 qualifies as a substitute based on these parameters. The primary difference is the number of positions (20 versus 19), which does not affect the fundamental electrical or mechanical compatibility of the connector interface itself. Both parts share identical pitch, contact type, mounting method, temperature range, current rating, and material specifications.

Engineering Selection Recommendations

The M22-2012005 is the designated substitute for the obsolete M22-2011905. Both components maintain identical electrical and mechanical specifications across all critical parameters: pitch, contact type, mounting method, temperature range, current capacity, and material composition. The M22-2012005 offers the additional advantage of active product status, ensuring continued availability and manufacturing support.

The single difference—20 positions versus 19—does not compromise interface compatibility. The connector remains cuttable, allowing position reduction to match legacy 19-position requirements if necessary. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the M22-2012005 directly replace the M22-2011905 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), contact type (male pin), mounting method (through hole), and electrical specifications (1A per contact, -55°C to 105°C). The M22-2012005 provides one additional position (20 versus 19), which does not affect mating interface compatibility.

Q: What is the significance of the "cuttable" designation?

A: Both the M22-2011905 and M22-2012005 are cuttable headers, meaning individual positions can be mechanically separated. This allows the 20-position M22-2012005 to be configured for 19-position applications if required.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Regulatory compliance is equivalent.

Q: Why is the M22-2011905 obsolete?

A: Product obsolescence is determined by the manufacturer. The M22-2012005 remains in active production and serves the same functional requirements.

Q: What are the mated stacking heights?

A: Both connectors support mated stacking heights of 5.9mm and 8.6mm, maintaining identical board-to-board spacing capability.

Q: Is the contact finish identical?

A: Yes. Both parts feature gold-plated mating contacts on phosphor bronze material, providing equivalent electrical conductivity and corrosion resistance.
