YB16SKW01-01-JB Equivalent & Substitute Parts

Part Overview

The YB16SKW01-01-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with illumination capability. This component is rated for 3A at 125V AC and 30V DC, designed for panel-mount front installation with neon white illumination. The part is currently obsolete, making identification of compatible substitutes essential for system maintenance, repair, and legacy equipment support.

Substitute Part Grouping Explanation

Substitution of the YB16SKW01-01-JB is determined by strict equivalence across electrical and mechanical parameters. The substitute part YB16SKW01-6B-JB maintains compatibility based on the following criteria:

Electrical Equivalence:

• Identical circuit configuration (SPDT)
• Identical switch function (On-On)
• Identical current rating (3A AC/DC)
• Identical voltage ratings (125V AC, 30V DC)

Mechanical Equivalence:

• Identical mounting type (Panel Mount, Front)
• Identical actuator type (Square Button)
• Identical panel cutout dimensions (Circular - 16.00mm Dia)
• Identical termination style (Solder, Quick Connect - 0.110")

Environmental Equivalence:

• Identical operating temperature range (-25°C to 50°C)
• Identical mechanical life (200,000 Cycles)
• Identical electrical life (100,000 Cycles)

Compliance Equivalence:

• Both ROHS3 Compliant
• Both REACH Unaffected
• Both classified as EAR99

The primary difference between these parts is the illumination technology: the main part uses neon white illumination at 110 VAC, while the substitute uses LED white illumination at 3.3 VDC. This difference does not affect the core switching function or electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-6B-JB is the active production equivalent of the obsolete YB16SKW01-01-JB. Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The substitute part is currently in active production status with confirmed inventory availability (1039 Pcs), whereas the main part is obsolete with limited remaining stock (700 Pcs).

Selection of the YB16SKW01-6B-JB is supported by:

• Identical SPDT switching capability and current/voltage ratings
• Identical mechanical form factor and panel cutout dimensions
• Identical termination compatibility for direct installation
• Full ROHS3 compliance and REACH compliance alignment
• Active production status ensuring long-term availability

The illumination technology difference (neon to LED) requires circuit-level evaluation only if the illumination voltage supply (110 VAC vs. 3.3 VDC) differs in the target application. The core switching function remains electrically equivalent.

Frequently Asked Questions (FAQ)

Q: Can YB16SKW01-6B-JB directly replace YB16SKW01-01-JB in existing installations?

A: Yes, for the switching function. Both parts have identical SPDT circuit configuration, current ratings (3A), voltage ratings (125V AC / 30V DC), mounting dimensions, and termination style. The illumination voltage differs (110 VAC vs. 3.3 VDC), so the illumination circuit must be evaluated separately.

Q: What is the primary difference between these two parts?

A: The illumination technology. YB16SKW01-01-JB uses neon white illumination at 110 VAC, while YB16SKW01-6B-JB uses LED white illumination at 3.3 VDC. All switching parameters are identical.

Q: Are both parts mechanically compatible with the same panel cutout?

A: Yes. Both parts require a circular 16.00mm diameter panel cutout and use identical quick-connect termination (0.110" / 2.8mm).

Q: Why is YB16SKW01-01-JB listed as obsolete?

A: The part has been superseded by the YB16SKW01-6B-JB, which uses LED illumination technology instead of neon. NKK Switches has transitioned this product line to the newer LED variant.

Q: What is the inventory status for each part?

A: YB16SKW01-01-JB (obsolete): 700 Pcs available. YB16SKW01-6B-JB (active): 1039 Pcs available.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both YB16SKW01-01-JB and YB16SKW01-6B-JB are ROHS3 Compliant and REACH Unaffected.

Q: What is the mechanical life expectancy for these switches?

A: Both parts are rated for 200,000 mechanical cycles and 100,000 electrical cycles under specified operating conditions (-25°C to 50°C).
