Substitute Part Grouping Explanation

Substitution for the M22-2582205 is determined by the following critical parameters:

Pitch and Position Count: All substitutes maintain 0.079" (2.00mm) mating pitch with 44 positions in 2 rows
Connector Type: Substitutes are headers with male pins for through-hole mounting
Contact Configuration: All maintain unshrouded, board-to-board or cable style with solder termination
Electrical Performance: Mating contact finish (gold), contact material (phosphor bronze or copper alloy), and current/voltage ratings must support the application
Environmental Compliance: RoHS3 compliance and UL94 V-0 flammability rating are maintained across all substitutes
Mechanical Compatibility: Overall contact length, insulation height, and row spacing determine physical fit

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents)

The Molex 0877584450 and Samtec MTMM-122 series variants are the preferred substitutes for the M22-2582205. All three manufacturers provide active product status with ROHS3 compliance and UL94 V-0 flammability certification. The Samtec MTMM-122 series offers extended operating temperature range (-55°C to 125°C) and higher current rating (3A per contact) compared to the original part, providing enhanced performance margin for new designs.

Secondary Substitutes (Amphenol ICC Minitek Series)

The Amphenol ICC 10075024-G01-22ULF and 10075024-F01-22ULF are functionally equivalent with active product status and RoHS compliance. These parts feature higher current rating (2A per contact) and specified voltage rating (200V AC/DC). The primary distinction is packaging format: 10075024-F01-22ALF is supplied in Tape & Reel format for automated assembly, while 10075024-F01-22ULF is supplied in Tube format for manual handling.

Reduced Position Variant

The Amphenol ICC 10075024-F01A22ULF provides a 22-position configuration with 21 positions loaded. This variant is suitable only for applications requiring reduced pin count and should not be used as a direct substitute for 44-position requirements.

Samtec MTMM-122 Series Selection

Within the Samtec MTMM-122 family, selection depends on contact finish and mating length requirements:

MTMM-122-02-F-D-195: Gold mating finish, 0.195" (4.95mm) contact length
MTMM-122-02-G-D-190: Gold mating and post finish, 0.190" (4.83mm) contact length
MTMM-122-02-S-D-190: Gold mating finish, tin post finish, 0.190" (4.83mm) contact length
MTMM-122-02-T-D-190: Tin mating finish, 0.190" (4.83mm) contact length, -55°C to 105°C operating range
MTMM-122-03-G-D-155: Gold mating and post finish, 0.155" (3.94mm) contact length

All Samtec variants maintain cuttable header construction, phosphor bronze contact material, and liquid crystal polymer insulation.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10075024-F01A22ULF (22-position) be used as a substitute for the M22-2582205 (44-position)?

A: No. The 10075024-F01A22ULF is a 22-position connector with only 21 positions loaded. It is not a direct substitute for applications requiring 44 positions. Use this part only when the application design specifically requires 22 positions.

Q: What is the difference between the Samtec MTMM-122-02-F-D-195 and MTMM-122-02-G-D-190?

A: Both parts maintain 44 positions at 2.00mm pitch with phosphor bronze contacts and LCP insulation. The primary differences are contact length (0.195" versus 0.190") and contact finish. The MTMM-122-02-F-D-195 has gold mating finish only, while the MTMM-122-02-G-D-190 has gold finish on both mating and post contacts.

Q: Are the Amphenol ICC Minitek parts (10075024-G01-22ULF and 10075024-F01-22ULF) electrically equivalent to the M22-2582205?

A: Yes. Both Minitek parts maintain 44 positions at 2.00mm pitch with male pins, through-hole solder termination, and gold-plated mating contacts. The Minitek series provides higher current rating (2A per contact versus 1A) and specified voltage rating (200V AC/DC). Contact material differs (copper alloy versus phosphor bronze) and insulation material is thermoplastic rather than nylon, but electrical performance is equivalent or superior.

Q: What is the difference between Tape & Reel (10075024-F01-22ALF) and Tube (10075024-F01-22ULF) packaging for the Amphenol ICC Minitek series?

A: Both parts are electrically and mechanically identical. Tape & Reel packaging is designed for automated pick-and-place assembly equipment, while Tube packaging is suitable for manual handling and lower-volume assembly. Select packaging based on assembly process requirements.

Q: Does the Molex 0877584450 have the same contact length as the M22-2582205?

A: No. The M22-2582205 has overall contact length of 0.346" (8.80mm), while the Molex 0877584450 has overall contact length of 0.378" (9.60mm). The mating contact length differs (0.197" versus 0.217") and post length differs (0.091" versus 0.102"). Verify mechanical fit in the application before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS compliant. The Samtec MTMM-122 series and Molex 0877584450 are specifically ROHS3 compliant. The Amphenol ICC Minitek series is RoHS compliant. Verify specific compliance requirements for your application.

Q: What is the operating temperature range for the Amphenol ICC Minitek substitutes?

A: Operating temperature range is not specified in the provided data for the Amphenol ICC Minitek series (10075024-G01-22ULF and 10075024-F01-22ULF). The original M22-2582205 operates from -40°C to 105°C. The Samtec MTMM-122 series provides extended range (-55°C to 125°C, except MTMM-122-02-T-D-190 which is -55°C to 105°C). Contact the manufacturer for Amphenol ICC operating temperature specifications if this parameter is critical for your application.
