Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between M22-1920046 and its substitutes depends on application-specific requirements:

M22-1900005 (Gold contact, Black) and M22-1920005 (Gold contact, Red) provide enhanced corrosion resistance through gold plating at reduced thickness (5.11µin versus 118.1µin tin). These are suitable for applications requiring superior contact reliability in corrosive environments or extended service life.

M22-1900046 (Tin contact, Black) maintains identical contact finish specifications to the main part while offering alternative color coding for circuit board identification or visual circuit tracing.

M22-1910005 (Gold contact, Blue) combines gold contact finish with blue housing for applications requiring specific color-coded jumper identification schemes.

All parts are electrically and mechanically interchangeable within the M22 series 2-position, 0.079" pitch connector family.

Frequently Asked Questions (FAQ)

Q: Can M22-1920046 be replaced with M22-1920005?

A: Yes. Both parts share identical electrical ratings (250V, 2A), mechanical dimensions (0.138" height, 0.079" pitch), and housing material (Polyester, Glass Filled). The difference is contact finish: M22-1920046 uses tin (118.1µin), while M22-1920005 uses gold (5.11µin). Both are ROHS3 compliant and Active status.

Q: What is the difference between tin and gold contact finishes in these connectors?

A: Tin contact finish (M22-1920046, M22-1900046) provides standard electrical conductivity with 118.1µin thickness. Gold contact finish (M22-1900005, M22-1910005, M22-1920005) offers enhanced corrosion resistance with 5.11µin thickness. Both finishes meet the 250V, 2A electrical requirements.

Q: Are color variations electrically equivalent?

A: Yes. Red (M22-1920046, M22-1920005), Black (M22-1900005, M22-1900046), and Blue (M22-1910005) housings are functionally identical. Color differences serve only for visual identification and circuit board documentation purposes.

Q: Can these connectors be used interchangeably on the same circuit board?

A: Yes, provided the 0.079" (2.00mm) pitch spacing and 0.138" (4.60mm) height match the PCB design. All listed parts maintain these specifications and are mechanically compatible within the M22 series.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates these connectors meet Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed substitute parts maintain ROHS3 compliance.

Q: Is there a difference in availability between these parts?

A: Inventory levels vary. M22-1900005 has 58,530 units in stock, M22-1920005 has 14,484 units, M22-1910005 has 23,214 units, and M22-1900046 has 4,703 units. Availability should be confirmed at time of procurement.
