Parameter Comparison

Engineering Selection Recommendations

The DF40C-50DP-0.4V(51) is the direct substitute for the obsolete DF40C-50DP-0.4V(57). Both components share identical electrical and mechanical specifications across all critical parameters: 50-position configuration, 0.40mm pitch, plug connector type with outer shroud contacts, and surface mount technology.

The substitute part offers the following advantages:

• Active Product Status: DF40C-50DP-0.4V(51) maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Enhanced Compliance: ROHS3 compliance and REACH unaffected status provide regulatory alignment with current environmental standards
• Improved Inventory: 38,426 units in stock compared to limited availability of the obsolete variant
• Standardized Packaging: Supplied in Tape & Reel (TR) format for automated assembly processes
• Documented Specifications: Complete technical parameters including contact finish, height above board, and mated stacking heights are fully specified

Both parts maintain identical MSL 1 (Unlimited) moisture sensitivity classification, ECCN EAR99 export control status, and HTSUS tariff classification 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can DF40C-50DP-0.4V(51) be used as a direct replacement for DF40C-50DP-0.4V(57)?

A: Yes. Both connectors share identical electrical and mechanical specifications: 50 positions, 0.40mm pitch, plug configuration with outer shroud contacts, and surface mount mounting type. The substitute part is manufactured by the same supplier (Hirose Electric Co Ltd) and maintains all critical compatibility parameters.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. DF40C-50DP-0.4V(57) is obsolete, while DF40C-50DP-0.4V(51) is active. The suffix designation (57 versus 51) indicates different manufacturing revisions or packaging variants within the same DF40 series. The substitute part includes documented specifications for contact finish (gold), contact finish thickness (2.00µin), and mated stacking heights (1.5mm through 4mm).

Q: Are there any compliance or certification differences?

A: Both parts carry identical ECCN EAR99 and HTSUS 8536.69.4040 classifications. The substitute part includes ROHS3 compliance and REACH unaffected status documentation. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What packaging format is available for the substitute part?

A: DF40C-50DP-0.4V(51) is supplied in Tape & Reel (TR) format, suitable for automated surface mount assembly processes.

Q: Are the mated stacking heights compatible?

A: The substitute part DF40C-50DP-0.4V(51) supports mated stacking heights of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm. Height above board is specified as 0.045" (1.14mm). Verify your application requirements against these specifications.

Q: Is inventory availability a concern?

A: The substitute part DF40C-50DP-0.4V(51) has 38,426 units in stock, providing substantial availability. The original part DF40C-50DP-0.4V(57) has limited inventory (927 units) and obsolete status, making the substitute the preferred selection for new designs and ongoing production.
