Key Parameters

Substitute Part Grouping Explanation

Substitution for the M22-2022305 is determined by the following critical parameters:

Primary Substitution Criteria:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Shape: Square

Acceptable Variations:

• Number of Positions: 46 or 48 (position count may vary based on application requirements)
• Insulation Material: Polyamide (PA6T) or Liquid Crystal Polymer (LCP)
• Contact Finish - Mating: Gold or Tin
• Operating Temperature: -40°C to 105°C or -55°C to 125°C (extended range acceptable)
• Current Rating: 1A or higher per contact

Substitute parts must maintain electrical and mechanical compatibility through identical pitch, row configuration, contact geometry, and termination method.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Same Manufacturer: M22-2022405 is the manufacturer-recommended substitute from Harwin Inc. This part maintains identical electrical and mechanical specifications to the M22-2022305 with the exception of position count (48 vs. 46). The M22-2022405 is active in production status, ensuring long-term availability and supply chain stability. Both parts share identical pitch, row spacing, contact material, and termination characteristics. Selection of M22-2022405 is appropriate when the additional 2 positions do not conflict with board layout constraints.

Alternative Substitutes - Cross-Manufacturer: The Samtec TMM-123 series provides functionally equivalent alternatives with enhanced electrical performance. All TMM-123 variants maintain the critical 0.079" (2.00mm) pitch and 2-row configuration required for mechanical compatibility. The TMM-123 series offers higher current rating (3.2A per contact vs. 1A), extended operating temperature range (-55°C to 125°C), and Liquid Crystal Polymer insulation material. These characteristics provide superior performance margins in demanding applications.

Contact Finish Considerations:

• TMM-123-02-G-D and TMM-123-06-G-D: Gold mating finish, matching the M22-2022305 specification
• TMM-123-02-S-D and TMM-123-06-S-D: Gold mating finish with tin post finish
• TMM-123-06-L-D: Gold mating finish with tin post finish, lower gold thickness
• TMM-123-06-T-D: Tin mating finish, suitable for cost-optimized applications

Contact Length Variations: TMM-123-06 variants feature extended post length (0.192" vs. 0.134") compared to TMM-123-02 variants (0.118"). Selection depends on PCB thickness and solder joint requirements.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can M22-2022405 be used as a direct replacement for M22-2022305? A: M22-2022405 is mechanically and electrically compatible with M22-2022305. The primary difference is position count: 48 positions versus 46. Direct substitution is possible if the additional 2 positions do not create board layout conflicts. Both parts share identical pitch (0.079"), row spacing, contact material, and termination method.

Q: What are the key differences between Harwin M22 and Samtec TMM-123 series? A: Both series maintain the critical 0.079" (2.00mm) pitch and 2-row configuration. Primary differences include: current rating (1A vs. 3.2A per contact), operating temperature range (-40°C to 105°C vs. -55°C to 125°C), insulation material (Polyamide vs. Liquid Crystal Polymer), and contact length options. TMM-123 series provides enhanced electrical performance and wider temperature range.

Q: Are all substitute parts cuttable like the M22-2022305? A: The M22-2022305 and M22-2022405 are specified as cuttable headers. The Samtec TMM-123 series is specified as standard headers without explicit cuttable designation. Verify cuttability requirements with application specifications before selection.

Q: What is the significance of contact finish variations in the TMM-123 series? A: Contact finish affects corrosion resistance and solderability. Gold finish (TMM-123-02-G-D, TMM-123-06-G-D, TMM-123-06-L-D, TMM-123-06-S-D) provides superior corrosion resistance. Tin finish (TMM-123-06-T-D) offers cost optimization with adequate performance in standard environments. Gold thickness varies: 20.0µin (0.51µm), 10.0µin (0.25µm), or 30.0µin (0.76µm) depending on part number.

Q: How do contact length differences affect PCB design? A: TMM-123-02 variants feature shorter post length (0.118" to 0.134") suitable for standard PCB thickness. TMM-123-06 variants feature extended post length (0.192") for thicker PCBs or applications requiring deeper solder joints. Overall contact length ranges from 0.323" to 0.377" depending on variant selection.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (M22-2022405 and all TMM-123 variants) are ROHS3 compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, eliminating special storage or handling requirements.

Q: What is the inventory status of substitute parts? A: M22-2022405 has 1066 pieces in stock. Samtec TMM-123 variants range from 665 to 846 pieces in stock across all finishes and contact length options, ensuring adequate supply for production requirements.
