Key Parameters

Substitute Part Grouping Explanation

The M22-2012305 is identified as a manufacturer-recommended substitute for the M22-2012246. Substitution eligibility is determined by the following parameters:

Matching Parameters:

• Manufacturer: Harwin Inc.
• Series: M22
• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature: -55°C ~ 105°C
• Current Rating: 1A per Contact
• Material Flammability Rating: UL94 V-0
• Insulation Material: Polyamide (PA6T), Nylon 6T
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters:

• Number of Positions: 22 (M22-2012246) vs. 23 (M22-2012305)
• Contact Finish - Mating: Tin (M22-2012246) vs. Gold (M22-2012305)
• Product Status: Obsolete (M22-2012246) vs. Active (M22-2012305)

Parameter Comparison

Engineering Selection Recommendations

The M22-2012305 is the manufacturer-designated substitute for the obsolete M22-2012246. Both components maintain ROHS3 compliance and identical electrical and thermal specifications. The M22-2012305 is currently in active production status with confirmed inventory availability.

The primary design consideration is the position count difference: the M22-2012305 provides 23 positions compared to the 22 positions of the original part. Applications requiring exactly 22 positions must account for this additional position in PCB layout and connector mating design.

The contact finish difference—gold plating on the M22-2012305 versus tin on the M22-2012246—provides enhanced corrosion resistance and contact reliability in the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the M22-2012305 directly replace the M22-2012246 in existing designs?

A: Direct replacement requires PCB layout modification to accommodate the additional 23rd position. The connector pitch, mounting type, and electrical specifications are identical, but the physical position count differs.

Q: What is the significance of the contact finish difference?

A: The M22-2012305 features gold-plated mating contacts, while the M22-2012246 uses tin finish. Gold plating provides superior corrosion resistance and is suitable for applications with higher environmental demands or extended shelf life requirements.

Q: Are both parts compatible with the same mating connectors?

A: Both parts use identical 2.00mm pitch and male pin contact configuration. Mating connectors designed for the M22 series at 2.00mm pitch are mechanically compatible with both parts, subject to position count accommodation.

Q: What is the inventory status for these parts?

A: The M22-2012246 is obsolete with 955 pieces in stock. The M22-2012305 is active production with 680 pieces available.
