Parameter Comparison

Engineering Selection Recommendations

Both the FTMH-110-03-L-DH and BC057-20-A-A-0150-L-C maintain Active product status and are RoHS3 compliant with MSL 1 ratings, confirming long-term availability and suitability for standard manufacturing environments.

The primary differences between these parts are operating temperature range and current rating per contact. The FTMH-110-03-L-DH supports -55°C to 125°C operation with 2.8A per contact, while the BC057-20-A-A-0150-L-C operates from -40°C to 105°C with 1A per contact. Selection between these parts depends on application-specific requirements for temperature extremes and current capacity.

Frequently Asked Questions (FAQ)

Q: Can BC057-20-A-A-0150-L-C replace FTMH-110-03-L-DH in all applications?

A: Both connectors share identical mechanical and electrical interface parameters including pitch, position count, row spacing, mounting type, and contact configuration. Substitution is valid when application requirements fall within the BC057-20-A-A-0150-L-C operating specifications of -40°C to 105°C and 1A per contact maximum.

Q: What are the key differences between these parts?

A: The FTMH-110-03-L-DH provides extended temperature range (-55°C to 125°C) and higher current capacity (2.8A per contact). The BC057-20-A-A-0150-L-C operates within -40°C to 105°C with 1A per contact. All other mechanical and electrical parameters are equivalent.

Q: Are packaging differences significant for substitution?

A: The FTMH-110-03-L-DH is supplied in Tube packaging, while BC057-20-A-A-0150-L-C is available in Cut Tape (CT) and Digi-Reel® formats. Packaging affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity levels. Both maintain Active product status.

Q: What should determine the choice between these connectors?

A: Selection should be based on application requirements for operating temperature range and maximum current per contact. If the application requires temperatures below -40°C or above 105°C, or current exceeding 1A per contact, the FTMH-110-03-L-DH is required. Otherwise, both parts are functionally equivalent.
