Substitute Part Grouping Explanation

Substitution eligibility for the LB15CKW01/C is determined by strict equivalence across the following critical parameters:

  • Electrical Specifications: Circuit configuration (SPDT), current rating (3A AC/DC), voltage ratings (125V AC / 30V DC), and switch function (On-Mom)
  • Mechanical Specifications: Mounting type (Panel Mount, Snap-In), panel cutout dimensions (22.00mm circular), and termination style (Solder, Quick Connect - 0.110")
  • Environmental & Lifecycle: Operating temperature range (-25°C to 70°C), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles)
  • Compliance: RoHS3 compliance and MSL rating (1)

The identified substitutes meet all these criteria. Variations in actuator type (plunger vs. round button) and actuator color do not affect electrical or mechanical compatibility within the LB series.

Engineering Selection Recommendations

LB15CKW01-C is the direct functional equivalent with Active product status. This part maintains identical electrical and mechanical specifications while offering improved procurement continuity. The round button actuator and red color represent design variations that do not affect circuit performance or panel integration.

LB15CKW01/CUL is the manufacturer-recommended alternative, also with Active product status. This part preserves the plunger actuator configuration of the original LB15CKW01/C while providing long-term availability assurance. RoHS compliance status for this variant was not provided in the specification data.

For new designs or long-term production planning, either LB15CKW01-C or LB15CKW01/CUL is suitable. Selection between these two should be based on actuator preference (round button vs. plunger) and any specific compliance documentation requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can LB15CKW01-C replace LB15CKW01/C in existing designs? A: Yes. Both parts share identical electrical ratings (3A/125V AC, 30V DC), circuit configuration (SPDT), mounting specifications (22.00mm panel cutout, snap-in), and termination style (0.110" quick connect). The actuator type difference (round button vs. plunger) does not affect electrical compatibility or panel mounting.

Q: What is the difference between LB15CKW01-C and LB15CKW01/CUL? A: Both are electrically and mechanically equivalent. LB15CKW01-C features a round button actuator with red color. LB15CKW01/CUL retains the plunger actuator configuration. Both are Active status products. Selection depends on actuator preference and panel design requirements.

Q: Why is LB15CKW01/C marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. LB15CKW01-C and LB15CKW01/CUL are active alternatives that provide equivalent functionality for ongoing procurement.

Q: Are all three parts RoHS3 compliant? A: LB15CKW01/C and LB15CKW01-C are confirmed ROHS3 Compliant. RoHS compliance status for LB15CKW01/CUL was not specified in the available data.

Q: Can these switches be used interchangeably in AC and DC circuits? A: Yes. All three parts are rated for both AC (125V) and DC (30V) operation with 3A current capacity, supporting both application types within their respective voltage limits.

Q: What is the mechanical life expectancy? A: All three parts are rated for 1,000,000 mechanical cycles and 100,000 electrical cycles under specified operating conditions (-25°C to 70°C).
