Substitute Part Grouping Explanation

The LB16SKW01-28-JB can be substituted with LB16SKW01-6B-JB based on the following electrical and mechanical compatibility criteria:

Matching Parameters (Substitution Basis):

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 3A (AC/DC)
• Voltage rating - AC: 125 V
• Voltage rating - DC: 30 V
• Mounting type: Panel Mount, Snap-In
• Panel cutout dimensions: Square - 16.20mm x 16.20mm
• Actuator type: Square, Button
• Termination style: Solder, Quick Connect - 0.110" (2.8mm)
• Operating temperature range: -25°C ~ 50°C
• Mechanical life: 200,000 Cycles
• Electrical life: 100,000 Cycles
• RoHS compliance: ROHS3 Compliant

Differing Parameter:

• Illumination type and voltage: The substitute part uses LED white illumination at 3.3 VDC instead of incandescent white illumination at 28 VAC/DC

The substitute maintains identical electrical switching characteristics and mechanical form factor, with the primary difference being the illumination technology and required supply voltage.

Parameter Comparison

Engineering Selection Recommendations

The LB16SKW01-6B-JB is a direct functional substitute for the obsolete LB16SKW01-28-JB. Both components maintain identical electrical switching performance, mechanical form factor, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The primary consideration for substitution is the illumination technology transition from incandescent to LED. This change requires modification of the illumination supply voltage from 28 VAC/DC to 3.3 VDC. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can LB16SKW01-6B-JB directly replace LB16SKW01-28-JB without circuit modifications?

A: The switching function and mechanical interface are identical. However, the illumination circuit requires modification due to the voltage difference (28 VAC/DC to 3.3 VDC) and technology change (incandescent to LED). The switch contacts themselves operate identically.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both parts require a square panel cutout of 16.20mm x 16.20mm and use identical snap-in mounting mechanisms.

Q: What is the impact of switching from incandescent to LED illumination?

A: LED illumination provides longer operational life, lower power consumption, and different brightness characteristics compared to incandescent. The supply voltage requirement changes from 28 VAC/DC to 3.3 VDC, necessitating circuit redesign for the illumination circuit only.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both LB16SKW01-28-JB and LB16SKW01-6B-JB are ROHS3 Compliant and REACH Unaffected.

Q: What is the difference in product availability?

A: LB16SKW01-28-JB is classified as obsolete, while LB16SKW01-6B-JB is in active production status, ensuring continued availability and supply chain support.

Q: Do the electrical ratings (current and voltage) differ between these parts?

A: No. Both parts maintain identical electrical ratings: 3A (AC/DC), 125V AC, and 30V DC. The switching characteristics are equivalent.
