Substitute Part Grouping Explanation

The DF1BZ-18DP-2.5DS serves as the active equivalent to the obsolete DF1BZ-18DP-2.5DS(27). Substitution is valid based on the following matching parameters:

• Identical base product number (DF1BZ)
• Matching connector type (Header)
• Identical contact type (Male Pin)
• Same number of positions (18) and rows (2)
• Identical mating pitch (0.098" / 2.50mm)
• Matching row spacing (0.098" / 2.50mm)
• Same mounting configuration (Through Hole, Right Angle)
• Identical termination method (Solder)
• Matching fastening type (Push-Pull)
• Same shrouding configuration (Shrouded - 4 Wall)
• Identical operating temperature range (-35°C ~ 85°C)
• Same voltage rating (150V)
• Matching contact finish (Tin)
• Identical insulation material (Polyamide/Nylon)
• Same flammability rating (UL94 V-0)

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-18DP-2.5DS is the direct active equivalent for the obsolete DF1BZ-18DP-2.5DS(27). Selection of this substitute part is based on:

• Complete electrical and mechanical parameter alignment across all critical specifications
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance certification maintained in the active equivalent
• UL94 V-0 flammability rating preserved for safety-critical applications
• EAR99 export classification for the active part supports broader distribution channels
• Moisture Sensitivity Level classification (MSL 1) indicates unlimited shelf life without special storage requirements

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-18DP-2.5DS directly replace DF1BZ-18DP-2.5DS(27) in existing designs?

A: Yes. All electrical and mechanical parameters are identical. The active part maintains the same connector type, pitch, position count, mounting configuration, and electrical ratings. The primary difference is product status (active vs. obsolete) and MSL classification.

Q: What is the significance of the MSL difference between the two parts?

A: The obsolete part lists MSL as "Not Applicable," while the active equivalent is classified as MSL 1 (Unlimited). MSL 1 indicates the component has unlimited shelf life and requires no special moisture-controlled storage conditions, providing practical advantages for inventory management.

Q: Are there packaging differences between these parts?

A: The obsolete part packaging is listed as unspecified. The active equivalent DF1BZ-18DP-2.5DS is supplied in Bulk packaging.

Q: Does the ECCN classification change affect procurement?

A: The obsolete part carries an OBSOLETE ECCN designation. The active equivalent is classified as EAR99, which is a standard export classification for commercial electronic components and does not impose additional export restrictions for most applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the obsolete and active parts maintain RoHS compliance certification, ensuring compatibility with RoHS-regulated applications and markets.

Q: What is the contact finish specification for mating surfaces?

A: Both parts feature tin contact finish on mating surfaces with a thickness of 39.4µin (1.00µm), providing consistent electrical contact characteristics and corrosion resistance.
