Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-5322146 is based on the following critical parameters that must remain consistent:

• Pitch and Row Spacing: 0.079" (2.00mm) mating pitch and row spacing are fundamental to PCB footprint compatibility
• Connector Type: Header, cuttable configuration for board-to-board applications
• Contact Type: Male pin configuration
• Mounting Type: Surface mount assembly requirement
• Termination Method: Solder termination
• Series Compatibility: M22 series maintains mechanical and electrical consistency
• Operating Temperature: -40°C ~ 105°C range
• Current Rating: 1A per contact minimum
• Compliance Standards: RoHS3 and UL94 V-0 flammability rating

The M22-5322205 qualifies as a substitute based on these parameters. The primary difference is position count (44 vs. 42), which represents a compatible extension within the same series architecture. Both parts share identical pitch, row spacing, mounting type, termination method, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The M22-5322205 is the designated substitute for the obsolete M22-5322146. Selection is based on the following factors:

Product Status: The M22-5322146 is obsolete, while the M22-5322205 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: Both parts maintain identical RoHS3 compliance and UL94 V-0 flammability ratings, meeting regulatory requirements for equivalent applications.

Electrical and Mechanical Compatibility: The substitute maintains all critical parameters including pitch, row spacing, contact configuration, mounting type, and termination method. The identical operating temperature range (-40°C ~ 105°C) and current rating (1A per contact) ensure functional equivalence in thermal and electrical performance.

Position Count Difference: The M22-5322205 provides 44 positions compared to 42 in the main part. This represents a compatible extension within the M22 series architecture. Applications requiring exactly 42 positions may utilize the cuttable header feature to achieve the required configuration, or PCB design may accommodate the additional 2 positions without functional impact.

Contact Finish Variation: The substitute features gold contact finish on mating surfaces compared to tin on the main part. Gold finish provides enhanced corrosion resistance and contact reliability, representing an improvement in long-term performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the M22-5322205 directly replace the M22-5322146 in existing designs?

A: Direct replacement is possible when PCB footprint and connector cavity accommodate the 44-position configuration. The identical pitch (2.00mm), row spacing, and mounting specifications ensure mechanical compatibility. If the design requires exactly 42 positions, the cuttable header feature allows trimming to the required length.

Q: What is the significance of the contact finish difference between tin and gold?

A: Both tin and gold finishes are acceptable for the 2.00mm pitch application. Gold finish on the M22-5322205 provides superior corrosion resistance and contact reliability over extended service life, particularly in environments with moisture or thermal cycling.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical current rating (1A per contact), operating temperature range (-40°C ~ 105°C), and contact material (phosphor bronze). Electrical performance is equivalent.

Q: What does "cuttable" mean for these header connectors?

A: The cuttable feature allows the connector strip to be mechanically separated at defined positions along the length. This enables customization of the final position count to match specific application requirements without requiring a unique part number.

Q: Are both parts suitable for high-reliability applications?

A: Yes. Both parts meet UL94 V-0 flammability requirements and maintain RoHS3 compliance. Moisture sensitivity level 1 (unlimited) indicates no special handling requirements. Both are suitable for industrial and commercial applications within the specified operating temperature range.

Q: What is the inventory status for these parts?

A: The M22-5322146 (obsolete) has 828 pieces in stock. The M22-5322205 (active) has 679 pieces in stock. For new designs, the active M22-5322205 is recommended to ensure continued availability.
