Engineering Selection Recommendations

Both the MTSW-105-07-S-D-175 and PEC05DAAN maintain active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on design requirements and supply availability.

The MTSW-105-07-S-D-175 features gold-plated mating contacts with a cuttable header design and operates across -55°C to 125°C. The PEC05DAAN provides a breakaway header configuration with tin-plated mating contacts and extends the lower operating temperature to -65°C. Both connectors support identical pitch, position count, row configuration, and current rating specifications.

Physical dimensions differ slightly: the PEC05DAAN exhibits a longer mating contact length (0.230" versus 0.175") and shorter post length (0.120" versus 0.155"), resulting in a marginally increased overall contact length (0.450" versus 0.430"). Insulation material differs between polyester glass-filled and PBT formulations, both meeting UL94 V-0 requirements.

Frequently Asked Questions (FAQ)

Q: Can PEC05DAAN directly replace MTSW-105-07-S-D-175 in existing designs?

A: Both connectors share identical pitch (0.100"), position count (10), row configuration (2), and current rating (3A) specifications. Physical dimension variations in contact length and overall height require verification against PCB layout and mating connector specifications before implementation.

Q: What is the difference between cuttable and breakaway header types?

A: The MTSW-105-07-S-D-175 features a cuttable design allowing individual position separation through cutting. The PEC05DAAN provides a breakaway configuration with pre-scored sections for position separation. Both achieve equivalent functional performance in board-to-board applications.

Q: Are the contact finish differences significant for substitution?

A: The MTSW-105-07-S-D-175 uses gold-plated mating contacts while PEC05DAAN uses tin-plated mating contacts. Both finishes support 3A current rating and maintain contact reliability. Gold plating provides enhanced corrosion resistance; tin plating offers cost efficiency. Selection depends on environmental exposure and application requirements.

Q: Do operating temperature ranges affect substitution eligibility?

A: The MTSW-105-07-S-D-175 operates -55°C to 125°C while PEC05DAAN operates -65°C to 125°C. Both ranges encompass standard industrial and commercial temperature requirements. The PEC05DAAN provides extended low-temperature capability for applications requiring sub-55°C operation.

Q: Are both parts RoHS3 compliant?

A: Yes, both MTSW-105-07-S-D-175 and PEC05DAAN maintain full ROHS3 compliance and UL94 V-0 flammability certification, supporting equivalent regulatory requirements.
