Engineering Selection Recommendations

The D4V-8166Z-N is the designated substitute for the obsolete D4V-8166Z. Both components maintain identical electrical specifications (5A at 125V AC / 24V DC), mechanical characteristics (90gf operating force, 30.0mm pretravel), and environmental ratings (IP65, -20°C to 60°C). Both parts carry RoHS compliance certification and MSL 1 rating, ensuring compatibility with modern manufacturing and storage requirements.

The transition from D4V-8166Z to D4V-8166Z-N involves no functional or performance trade-offs. The active status of the D4V-8166Z-N ensures continued availability and supply chain stability for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the D4V-8166Z-N directly replace the D4V-8166Z in existing applications?

A: Yes. The D4V-8166Z-N maintains identical electrical ratings (5A, 125V AC / 24V DC), circuit configuration (SPDT), mechanical specifications (90gf operating force, 30.0mm pretravel), and environmental protection (IP65). Both components use screw terminal connections and chassis mount installation. No circuit modifications or mechanical adjustments are required.

Q: What is the difference between the D4V-8166Z and D4V-8166Z-N?

A: The primary difference is product status: D4V-8166Z is obsolete, while D4V-8166Z-N is active. Packaging differs (standard vs. bulk). Electrical and mechanical parameters are equivalent, with pretravel specifications differing by 0.001" (within tolerance). Both are RoHS compliant with MSL 1 rating.

Q: Are there packaging considerations when switching from D4V-8166Z to D4V-8166Z-N?

A: The D4V-8166Z-N is supplied in bulk packaging, whereas the D4V-8166Z used standard packaging. Bulk packaging may require adjustment to receiving and inventory procedures but does not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the D4V-8166Z and D4V-8166Z-N are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory and manufacturing requirements.

Q: What is the operating temperature range for both components?

A: Both parts operate across -20°C to 60°C. This range applies to all electrical and mechanical specifications listed.
