Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet RoHS compliance and UL94 V-0 flammability requirements, ensuring regulatory alignment with the MTSW-120-07-G-S-240.

Amphenol ICC BERGSTIK® II Series (68000-120HLF, 68001-120HLF, 68001-220HLF) provide the closest electrical and mechanical equivalence with extended operating temperature range to -65°C. Contact finish thickness varies: 68000-120HLF and 68001-120HLF offer 30.0µin mating finish, while 68001-220HLF provides 15.0µin. All three maintain phosphor bronze contacts with gold plating and 3A per contact rating.

Amphenol ICC BERGSTIK® Series (77311-122-20LF, 77311-124-20LF) offer phosphor bronze contacts with gold mating finish (30.0µin) and tin-plated posts. These parts extend operating temperature to -65°C and maintain 3A per contact rating. Contact length specifications differ: 77311-122-20LF provides 0.305" mating length, while 77311-124-20LF provides 0.266" mating length.

TE Connectivity AMPMODU Mod II (2-826926-0) features copper alloy contacts with tin plating and higher current rating of 5A. Operating temperature range is -65°C to 105°C, which does not extend to the upper 125°C limit of the original part. This substitute is suitable for applications not requiring the full upper temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use 2-826926-0 as a direct replacement for MTSW-120-07-G-S-240?

A: The 2-826926-0 meets core substitution criteria including pitch, position count, mounting type, and fastening. However, its maximum operating temperature is 105°C compared to the MTSW-120-07-G-S-240's 125°C upper limit. Use this substitute only in applications where the operating temperature does not exceed 105°C.

Q: What is the difference between the Amphenol BERGSTIK® II and BERGSTIK® series?

A: Both series maintain identical pitch, position count, and electrical ratings. The primary differences are contact length specifications and post finish. BERGSTIK® II parts (68000/68001 series) have shorter overall contact lengths, while BERGSTIK® parts (77311 series) feature tin-plated posts in addition to gold-plated mating surfaces.

Q: Are all substitute parts cuttable like the MTSW-120-07-G-S-240?

A: The MTSW-120-07-G-S-240 is specified as cuttable. The Amphenol BERGSTIK® II parts are specified as standard headers, while the Amphenol BERGSTIK® parts and TE Connectivity part are specified as breakaway headers. Verify mechanical compatibility with your application's specific requirements.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are RoHS compliant and carry UL94 V-0 flammability rating. The MTSW-120-07-G-S-240 is ROHS3 compliant, while Amphenol parts are RoHS compliant. All parts have unlimited moisture sensitivity rating (MSL 1).

Q: What is the difference in contact finish thickness between parts?

A: Contact finish thickness varies across substitutes. The MTSW-120-07-G-S-240 has 10.0µin (0.25µm) gold mating finish. Amphenol BERGSTIK® II parts offer 30.0µin or 15.0µin depending on model. Amphenol BERGSTIK® and TE Connectivity parts have 78.7µin (2.00µm) finish thickness. Thicker finishes provide enhanced durability in high-cycle mating applications.

Q: Can I substitute based on current rating alone?

A: No. While the TE Connectivity 2-826926-0 offers higher current rating (5A vs. 3A), substitution requires matching all critical parameters including pitch, position count, mounting type, termination, and operating temperature range. The 2-826926-0's 105°C upper temperature limit may restrict its use in applications requiring the full -55°C to 125°C range.
