Substitute Part Grouping Explanation

Substitution of the obsolete 8121J84CLE92 is determined by strict equivalence across electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Mom), current rating (1A AC/DC), voltage ratings (120V AC / 28V DC), and electrical life (60,000 cycles).

Mechanical Parameters: Mounting type (Panel Mount, Snap-In), actuator type (Square, Button, Flush), termination style (PC Pin), and panel cutout dimensions (Rectangular - 15.24mm x 12.70mm).

Environmental Parameters: Operating temperature range (-30°C to 75°C), moisture sensitivity level (1 - Unlimited), and RoHS compliance status.

The substitute part 8121J84CRE92 meets all these criteria while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The C&K 8121J84CRE92 serves as the direct substitute for the obsolete 8121J84CLE92. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in all circuit applications.

The substitute part offers the following advantages:

Product Status: The 8121J84CRE92 maintains active product status, ensuring long-term availability and continued manufacturing support compared to the obsolete main part.

Compliance Enhancement: The substitute part carries ROHS3 compliance certification, representing an updated compliance standard relative to the RoHS Compliant status of the main part. Both parts satisfy RoHS requirements.

Additional Certification: The 8121J84CRE92 includes REACH Affected status documentation, providing enhanced regulatory traceability for applications requiring comprehensive material compliance records.

Packaging Consideration: The substitute part is supplied in Tray packaging, whereas the main part packaging format is not specified. This represents a packaging difference only and does not affect electrical or mechanical performance.

Feature Addition: The substitute part includes tactile feedback as a documented feature, providing enhanced user interface feedback during switch actuation.

Selection of the 8121J84CRE92 is appropriate for all applications currently specified for the 8121J84CLE92, with the added benefit of active product availability and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 8121J84CRE92 directly replace the 8121J84CLE92 in existing designs?

A: Yes. The 8121J84CRE92 maintains identical electrical ratings (1A at 120V AC / 28V DC), mechanical configuration (Panel Mount, Snap-In with 15.24mm x 12.70mm cutout), circuit topology (SPDT), and operating parameters (-30°C to 75°C). Direct substitution is supported without design modification.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the RoHS directive. The 8121J84CRE92 carries the updated ROHS3 certification, while the main part carries the earlier RoHS Compliant designation. Both satisfy RoHS requirements.

Q: Does the packaging difference (Tray vs. unspecified) affect component performance?

A: No. Packaging format affects only logistics, storage, and handling procedures. Electrical and mechanical performance characteristics remain identical regardless of packaging type.

Q: What does the tactile feedback feature on the 8121J84CRE92 provide?

A: Tactile feedback is a mechanical characteristic that provides perceptible resistance and response during switch actuation. This feature enhances user interface feedback but does not alter electrical switching performance or circuit compatibility.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both the 8121J84CLE92 and 8121J84CRE92 are rated for 1A (AC/DC) at 120V AC and 28V DC. They support identical electrical load specifications and circuit requirements.

Q: What does the Moisture Sensitivity Level 1 (Unlimited) rating indicate?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. The part does not require special moisture control during storage, handling, or assembly processes.

Q: Is the 8121J84CRE92 available in the same quantity as the main part?

A: Inventory levels differ. The main part 8121J84CLE92 has 1119 pieces in stock, while the substitute 8121J84CRE92 has 923 pieces in stock. Both are available as new original components.
