Key Parameters

Substitute Part Grouping Explanation

The D4V-8122Z has one manufacturer-recommended substitute: D4V-8122Z-N. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current rating (5A AC/DC)
• Voltage ratings (125V AC, 24V DC)
• Actuator type (Cross Roller Plunger)
• Mounting type (Chassis Mount)
• Termination style (Screw Terminal)
• Ingress protection rating (IP65)
• Operating temperature range (-20°C to 60°C)
• Electrical and mechanical life specifications

The D4V-8122Z-N maintains full electrical and mechanical compatibility with the obsolete D4V-8122Z, with the primary distinction being active product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The D4V-8122Z-N is the manufacturer-recommended substitute for the obsolete D4V-8122Z. Both parts maintain identical electrical specifications, mechanical life ratings, and environmental protection classifications. The D4V-8122Z-N carries active product status, ensuring continued availability and supply chain support. Both parts are RoHS compliant, meeting current environmental regulatory requirements. The negligible variance in operating force (1000gf versus 999gf) and overtravel (0.158" versus 0.157") falls within normal manufacturing tolerances and does not affect functional equivalence. For new designs or system replacements, the D4V-8122Z-N should be specified to ensure long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the D4V-8122Z-N directly replace the D4V-8122Z in existing applications?

A: Yes. The D4V-8122Z-N is electrically and mechanically equivalent to the D4V-8122Z. Both parts share identical circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style. The minor differences in operating force and overtravel are within manufacturing tolerance and do not affect functional performance.

Q: What is the primary reason for substitution?

A: The D4V-8122Z is classified as obsolete product status. The D4V-8122Z-N is the active equivalent, ensuring continued procurement availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: Yes. The D4V-8122Z is supplied in standard packaging, while the D4V-8122Z-N is supplied in bulk packaging. This distinction does not affect electrical or mechanical performance.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the D4V-8122Z and D4V-8122Z-N are RoHS compliant and rated for IP65 ingress protection (dust tight, water resistant). Both operate across the same temperature range of -20°C to 60°C.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on equivalence in circuit configuration (SPDT), switch function (On-Momentary), current rating (5A AC/DC), voltage ratings (125V AC / 24V DC), actuator type (Cross Roller Plunger), mounting type (Chassis Mount), termination style (Screw Terminal), and ingress protection rating (IP65).
