Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2581346 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 26
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters:

• Operating Temperature Range: -40°C ~ 105°C or equivalent
• Insulation Material: Polyamide (PA6T), Nylon 6T, or Thermoplastic
• Contact Material: Phosphor Bronze or Copper Alloy
• Shrouding: Unshrouded

The substitute parts listed below meet all primary matching criteria and maintain compatibility across secondary parameters. Two substitute parts are identified from Amphenol ICC (FCI) within the Minitek® 2.00mm series, both maintaining the 26-position, 2-row configuration with identical pitch specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (26-Position Configuration):

The parts 10075024-F01-13ULF and 10075024-G01-13ULF from Amphenol ICC (FCI) are active products that maintain full compatibility with the M22-2581346 across all primary matching criteria. Both parts are RoHS compliant and carry UL94 V-0 flammability ratings. The Amphenol ICC parts feature gold-plated mating contacts compared to the tin finish of the original part, and provide higher current ratings (2A versus 1A per contact) with specified voltage ratings (200V AC/DC). These characteristics represent functional improvements suitable for direct substitution in new designs and ongoing production.

Alternative Consideration (20-Position Configuration):

The M22-2581046 from Harwin Inc. is an active product within the same M22 series, maintaining identical pitch, row spacing, and electrical characteristics. However, this part features 20 positions rather than 26, making it suitable only for applications where the reduced position count is acceptable. This part remains within the Harwin product line and shares the same insulation material and contact specifications as the original M22-2581346.

Compliance Status:

All substitute parts maintain ROHS compliance and UL94 V-0 flammability ratings. The Amphenol ICC parts carry REACH Affected status, while the Harwin M22-2581046 maintains REACH Unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 10075024-F01-13ULF and 10075024-G01-13ULF be used interchangeably with the M22-2581346?

A: Both Amphenol ICC parts maintain identical position count (26), row configuration (2 rows), pitch (0.079" / 2.00mm), and all primary connector specifications. The primary differences are contact finish (gold versus tin), contact length dimensions, and higher current/voltage ratings. These parts are direct functional substitutes for the obsolete M22-2581346.

Q: What is the difference between 10075024-F01-13ULF and 10075024-G01-13ULF?

A: Both parts are identical in configuration and electrical specifications. The difference lies in contact finish thickness on the mating surface: 10075024-F01-13ULF has flash gold plating, while 10075024-G01-13ULF has 30.0µin (0.76µm) gold plating. Both maintain the same 78.7µin (2.00µm) tin finish on the post.

Q: Why does the M22-2581046 have fewer positions than the original part?

A: The M22-2581046 is a 20-position variant within the same M22 series. While it shares identical pitch, row spacing, and electrical characteristics, it is designed for applications requiring fewer connection points. This part is suitable only if your application can accommodate the reduced position count.

Q: Are there any mechanical compatibility concerns when substituting with Amphenol ICC parts?

A: The Amphenol ICC Minitek® 2.00mm series parts have slightly shorter overall contact length (0.295" / 7.49mm versus 0.346" / 8.80mm) and shorter mating contact length (0.157" / 4.00mm versus 0.197" / 5.00mm). These dimensional differences must be evaluated against your specific PCB design and mating connector specifications to ensure proper engagement and contact pressure.

Q: What is the significance of the gold plating on the Amphenol ICC parts?

A: Gold plating on the mating contacts provides improved corrosion resistance and contact reliability compared to tin finish. The Amphenol ICC parts offer this enhancement along with higher current ratings (2A versus 1A per contact), making them suitable for applications with more demanding electrical requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The M22-2581046 is ROHS3 compliant. The Amphenol ICC parts (10075024-F01-13ULF and 10075024-G01-13ULF) are RoHS compliant. All parts meet current environmental compliance standards.

Q: What packaging options are available for these substitute parts?

A: The M22-2581046 is supplied in bulk packaging. The Amphenol ICC parts (10075024-F01-13ULF and 10075024-G01-13ULF) are supplied in tube packaging. Packaging selection may impact procurement lead times and handling requirements.
