Key Parameters

Substitute Part Grouping Explanation

Substitution for the FTMH-110-03-L-DH is determined by strict alignment of the following electrical and mechanical parameters:

• Connector type (Header) and contact type (Male Pin)
• Mating pitch of 0.039" (1.00mm)
• 20-position configuration in 2-row arrangement
• Row spacing of 0.039" (1.00mm)
• Surface mount, right-angle mounting orientation
• Solder termination with push-pull fastening
• Liquid Crystal Polymer insulation material
• Gold-plated mating contacts
• UL94 V-0 flammability rating
• ROHS3 compliance

The BC057-20-A-A-0150-L-C from GCT meets these core substitution criteria and is classified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BC057-20-A-A-0150-L-C is the manufacturer-recommended substitute for the FTMH-110-03-L-DH. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

The substitute part is currently in active production status with 3424 units available in inventory, compared to the discontinued status of the original part. Both connectors share identical mating pitch, position count, row configuration, and mounting orientation, ensuring mechanical and electrical compatibility in board-to-board applications.

Differences in operating temperature range (-40°C ~ 105°C versus -55°C ~ 125°C) and current rating per contact (1A versus 2.8A) should be evaluated against specific application requirements. Contact material differs (Copper Alloy versus Phosphor Bronze), and mating contact length is 0.059" (1.50mm) compared to 0.065" (1.65mm), with corresponding insulation height variation of 0.122" (3.10mm) versus 0.125" (3.18mm).

Frequently Asked Questions (FAQ)

Q: What determines if BC057-20-A-A-0150-L-C can substitute for FTMH-110-03-L-DH?

A: Substitution is based on matching connector type, contact type, mating pitch (1.00mm), position count (20), row configuration (2 rows), row spacing (1.00mm), mounting type (surface mount right-angle), termination method (solder), fastening type (push-pull), insulation material (LCP), contact finish (gold), and flammability rating (UL94 V-0). Both parts meet these criteria.

Q: Are there differences in electrical performance between these parts?

A: The current rating per contact differs: FTMH-110-03-L-DH is rated at 2.8A per contact, while BC057-20-A-A-0150-L-C is rated at 1A per contact. Operating temperature ranges also differ: -55°C ~ 125°C versus -40°C ~ 105°C. These differences should be evaluated against application specifications.

Q: Will the BC057-20-A-A-0150-L-C fit in the same PCB footprint?

A: Mating pitch and row spacing are identical (0.039" / 1.00mm), ensuring compatible PCB footprints. Minor dimensional variations exist in contact length (0.059" versus 0.065") and insulation height (0.122" versus 0.125"), which may affect mating depth and clearance considerations in specific board designs.

Q: What is the availability status of the substitute part?

A: BC057-20-A-A-0150-L-C is in active production status with 3424 units currently in stock, compared to the discontinued status of FTMH-110-03-L-DH.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both connectors.
