• Moisture Sensitivity: MSL 1 rating provides superior moisture handling compared to the obsolete variant

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-18DP-2.5DS directly replace DF1BZ-18DP-2.5DS(26)?

A: Yes. Both parts share identical base product number, position count (18), pitch specification (2.50mm), connector type (header), and contact configuration (male pin). The substitute is the active production equivalent.

Q: What is the significance of the (26) designation in the original part number?

A: The (26) suffix in DF1BZ-18DP-2.5DS(26) represents a specific variant or revision code. The substitute DF1BZ-18DP-2.5DS without this suffix is the current production version maintaining the same core specifications.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified in available documentation. The substitute is supplied in bulk packaging. Verify packaging requirements for your application.

Q: What compliance standards apply to the substitute part?

A: The DF1BZ-18DP-2.5DS is RoHS compliant and carries UL94 V-0 material flammability rating, meeting current environmental and safety standards.

Q: Is the operating temperature range suitable for my application?

A: The substitute operates across -35°C to 85°C. Verify this range meets your specific thermal requirements before implementation.

Q: What is the moisture sensitivity level, and does it affect storage?

A: The substitute carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply.
