Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-102-07-T-S-240 and 929834-01-02-RK are active products with UL94 V-0 flammability ratings and RoHS compliance, establishing baseline suitability for modern electronic applications.

The MTSW-102-07-T-S-240 supports a wider operating temperature range (-55°C to 105°C) and higher current rating (3A), making it the preferred choice for applications requiring extended low-temperature performance or higher current capacity.

The 929834-01-02-RK operates within -40°C to 105°C and carries a 2.5A current rating. This substitute is suitable for applications where the lower temperature limit and reduced current capacity do not present constraints. The breakaway connector type offers design flexibility compared to the cuttable design of the primary part.

Both parts share identical pitch, position count, mounting method, and termination approach, ensuring mechanical and electrical compatibility at the board interface level. The minor dimensional variations in contact length fall within typical manufacturing tolerances for this connector category and do not affect mating performance.

Frequently Asked Questions (FAQ)

Q: Can the 929834-01-02-RK directly replace the MTSW-102-07-T-S-240 in all applications?

A: Direct replacement is possible for applications operating within -40°C to 105°C and requiring maximum current of 2.5A. Applications requiring the full -55°C lower temperature limit or 3A current capacity require the original MTSW-102-07-T-S-240.

Q: What is the significance of the connector type difference (Cuttable vs. Breakaway)?

A: Cuttable connectors allow individual positions to be separated by cutting, while breakaway connectors feature pre-scored sections for position separation. Both achieve the same functional result; the choice depends on assembly process requirements and design preferences.

Q: Are the contact length variations between these parts critical?

A: The contact length differences (0.240" vs. 0.235" mating length) are minor and within standard tolerances for this connector class. These variations do not affect mating performance or electrical characteristics when used with compatible receptacles.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the MTSW-102-07-T-S-240 and 929834-01-02-RK are RoHS compliant and carry UL94 V-0 flammability ratings, meeting current regulatory standards for electronic component use.

Q: What is the inventory availability difference between these parts?

A: The MTSW-102-07-T-S-240 has 777 pieces in stock, while the 929834-01-02-RK has 4131 pieces available. The 3M part offers significantly higher inventory availability for immediate procurement needs.
