Environmental Rating: Both parts carry MSL 1 (Unlimited) classification, indicating identical moisture sensitivity performance and storage requirements.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Original inventory of the DF50-40DP-1H(76) remains available for immediate requirements, with the DF50-40DP-1H(51) providing long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between DF50-40DP-1H(76) and DF50-40DP-1H(51)?

A: The primary difference is product status. The DF50-40DP-1H(76) is obsolete, while the DF50-40DP-1H(51) is active in production. Both parts share identical electrical and mechanical specifications for the 40-position, 1.00mm pitch connector configuration. The suffix designation (76 vs. 51) indicates different manufacturing variants within the DF50 series.

Q: Are these parts electrically interchangeable?

A: Yes. Both parts maintain identical contact count (40 positions), mating pitch (1.00mm), and series designation (DF50). They are designed to mate with the same connector interfaces and carry identical electrical ratings (1A current, 100V voltage).

Q: What are the packaging differences?

A: The DF50-40DP-1H(76) packaging specification is not provided in the technical data. The DF50-40DP-1H(51) is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly operations.

Q: Do both parts meet current regulatory requirements?

A: The DF50-40DP-1H(51) carries RoHS Compliance certification and maintains EAR99 export classification. Both parts share identical HTSUS tariff code (8536.69.4040) and MSL 1 (Unlimited) environmental rating.

Q: What is the inventory status for each part?

A: The DF50-40DP-1H(76) has 1074 pieces in stock as new original inventory. The DF50-40DP-1H(51) has 1809 pieces in stock as new original inventory, providing greater supply availability for ongoing production requirements.

Q: Can the DF50-40DP-1H(51) be used in new designs?

A: Yes. The DF50-40DP-1H(51) is active in production and carries current regulatory compliance certifications. It is suitable for new design implementations requiring 40-position, 1.00mm pitch rectangular connectors in the DF50 series.

Q: Are there any mechanical mounting differences?

A: The DF50-40DP-1H(51) is specified as Surface Mount, Right Angle with solder termination and latch lock fastening. The mounting specification for DF50-40DP-1H(76) is not provided in the available technical data.
