Substitute Part Grouping Explanation

The DF50-40DP-1V(51) is identified as a manufacturer-recommended substitute for the DF50-40DP-1V(52). Both parts belong to the Hirose DF50 series and share identical electrical and mechanical specifications across all critical parameters that determine connector compatibility and interchangeability.

Substitution is valid based on the following matching criteria:

• Same connector series (DF50)
• Identical number of positions (40) and row configuration (2 rows)
• Identical mating pitch (0.039" / 1.00mm)
• Identical contact type (Male Blade)
• Identical mounting type (Surface Mount)
• Identical termination method (Solder)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical fastening type (Latch Lock)
• Identical electrical ratings (1A current, 100V voltage)
• Identical operating temperature range (-35°C ~ 85°C)
• Identical compliance certifications (UL94 V-0, ROHS3, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

Both the DF50-40DP-1V(52) and DF50-40DP-1V(51) are active production parts from Hirose Electric Co., Ltd. and carry identical compliance certifications including UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. The parts are functionally equivalent for all applications requiring a 40-position, 1.00mm pitch surface mount rectangular connector header with solder termination and latch lock fastening.

Selection between these part numbers may be based on inventory availability and procurement lead times. The DF50-40DP-1V(51) currently maintains higher inventory levels (4247 pcs) compared to the DF50-40DP-1V(52) (1856 pcs), making it a viable alternative when supply chain considerations are relevant.

Frequently Asked Questions (FAQ)

Q: Are DF50-40DP-1V(52) and DF50-40DP-1V(51) fully interchangeable?

A: Yes. Both parts share identical electrical specifications, mechanical dimensions, contact configurations, and compliance certifications. They are direct substitutes within the DF50 series.

Q: What determines compatibility between these connector headers?

A: Compatibility is determined by matching pitch (1.00mm), position count (40), row configuration (2 rows), contact type (Male Blade), mounting method (Surface Mount), and electrical ratings (1A / 100V). Both parts meet all these criteria identically.

Q: Do these parts have different contact finish specifications?

A: The DF50-40DP-1V(51) includes specified contact finish thickness values (2.00µin / 0.051µm) for both mating and post finishes, while the DF50-40DP-1V(52) does not list these thickness specifications in the provided data. Both use gold plating on brass contacts.

Q: Are there any packaging differences?

A: Both parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
