MTSW-103-07-L-S-180 Equivalent & Substitute Parts

Part Overview

The MTSW-103-07-L-S-180 is a vertical through-hole rectangular connector header manufactured by Samtec Inc. in the Flex Stack, MTSW series. This 3-position connector operates at 0.100" (2.54mm) pitch and is designed for board-to-board or cable applications with solder termination and push-pull fastening. The part is currently active in production with 747 units in stock.

Equivalent and substitute parts are identified based on matching electrical and mechanical parameters: 0.100" (2.54mm) pitch, 3-position single-row configuration, through-hole mounting, solder termination, push-pull fastening, square contact shape, UL94 V-0 flammability rating, and 3A current rating. Substitutes must maintain compatibility with these core specifications while accommodating minor variations in contact geometry and finish specifications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

The 68000-403HLF (Amphenol ICC BERGSTIK® II) is the preferred substitute for new designs. It maintains all critical electrical and mechanical parameters, operates across the required temperature range (-65°C to 125°C), carries ROHS3 compliance, and is actively produced. The tin contact finish (100.0µin) provides robust durability for standard applications. Packaging is supplied in bags.

The 0022284030 (Molex KK254) is an alternative active substitute with ROHS3 compliance. It features a slightly longer mating contact (0.240" vs. 0.180") and tin finish. The insulation height is marginally reduced (0.090" vs. 0.100"), which remains within acceptable tolerance for 2.54mm pitch headers. This part is actively produced with high inventory availability (14,125 units).

Secondary Substitutes (Active Status, RoHS Compliant):

The 68000-103HLF, 68000-203HLF, 68001-103HLF, 68001-203HLF, and 68001-403HLF (all Amphenol ICC BERGSTIK® II variants) are active substitutes with RoHS compliance. These parts differ primarily in contact finish thickness and post length. The 68001 series offers extended post length (0.120" vs. 0.095"), accommodating thicker PCB assemblies. Gold-finished variants (68000-103HLF, 68000-203HLF, 68001-103HLF, 68001-203HLF) provide enhanced corrosion resistance; tin-finished variants (68000-403HLF, 68001-403HLF) offer cost efficiency.

Obsolete Substitutes (Not Recommended for New Designs):

The 68000-103 and 68000-403H (Amphenol ICC BERGSTIK® II) are obsolete and RoHS non-compliant. The 69190-103 (Amphenol ICC BERGSTIK® II) is also obsolete and RoHS non-compliant. These parts are suitable only for legacy system maintenance or repair where original specifications must be preserved. New designs should not incorporate these parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute the MTSW-103-07-L-S-180 with the 0022284030 (Molex KK254)?

A: Yes. Both connectors share the critical parameters: 0.100" (2.54mm) pitch, 3-position single-row configuration, through-hole solder termination, push-pull fastening, square male pin contacts, and UL94 V-0 flammability rating. The 0022284030 features tin contact finish and slightly longer mating contact length (0.240" vs. 0.180"), which are acceptable variations. Insulation height is marginally reduced (0.090" vs. 0.100") but remains compatible with standard 2.54mm pitch header applications. Both parts are ROHS3 compliant and actively produced.

Q: What is the difference between the 68000-103HLF and 68001-103HLF?

A: Both are Amphenol ICC BERGSTIK® II headers with identical pitch, position count, and electrical ratings. The primary difference is contact post length: 68000-103HLF has 0.095" post length, while 68001-103HLF has 0.120" post length. The extended post length in the 68001 series accommodates thicker PCB assemblies. Select based on your PCB thickness requirements. Both are active and RoHS compliant.

Q: Can I use the 69190-103 as a substitute?

A: The 69190-103 is electrically and mechanically compatible but is obsolete and RoHS non-compliant. It is suitable only for legacy system maintenance or repair where original specifications must be preserved. For new designs, use active substitutes such as 68000-403HLF or 0022284030.

Q: What is the difference between gold and tin contact finishes?

A: Gold-finished contacts (68000-103HLF, 68000-203HLF, 68001-103HLF, 68001-203HLF, 69190-103) provide superior corrosion resistance and are preferred for high-reliability applications or environments with moisture exposure. Tin-finished contacts (0022284030, 68000-403H, 68000-403HLF, 68001-403HLF) offer cost efficiency and are suitable for standard industrial applications. Both finishes meet the electrical requirements for 3A current rating at 2.54mm pitch.

Q: Does packaging (Bulk vs. Bag) affect compatibility?

A: No. Packaging format (Bulk or Bag) does not affect electrical or mechanical compatibility. It is a logistics consideration only. Select based on your procurement and inventory management requirements.

Q: What is the operating temperature range for these substitutes?

A: The MTSW-103-07-L-S-180 operates from -55°C to 125°C. All identified substitutes operate across -65°C to 125°C or -65°C to 130°C, which exceeds the original specification. All substitutes are suitable for the full operating temperature range of the MTSW-103-07-L-S-180.

Q: Are all substitutes ROHS3 compliant?

A: No. The 68000-403HLF is ROHS3 compliant. The 68000-103HLF, 68000-203HLF, 68001-103HLF, 68001-203HLF, and 68001-403HLF are RoHS compliant. The 0022284030 is ROHS3 compliant. The 68000-103, 68000-403H, and 69190-103 are RoHS non-compliant. For new designs requiring ROHS3 compliance, use 68000-403HLF or 0022284030.
