Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16KKW01 requires matching of critical electrical and mechanical parameters that define functional compatibility. The primary substitution criteria are:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (1A AC/DC minimum)
• Voltage ratings (125V AC, 30V DC minimum)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular 12.30mm Dia)
• Operating temperature range (-25°C ~ 70°C)
• Mechanical and electrical life specifications

The identified substitute part TB16KKW01 from NKK Switches represents an alternative within the manufacturer's product portfolio. However, this substitute differs in circuit function and illumination characteristics, requiring detailed parameter comparison for compatibility assessment.

Engineering Selection Recommendations

The KB16KKW01 is classified as obsolete, necessitating component replacement for new designs or system maintenance. The TB16KKW01 is an active product from the same manufacturer, offering continued availability and supply chain stability.

Selection between these components must be based on:

• Functional circuit requirements (SPDT vs. alternative configurations)
• Illumination requirements (TB16KKW01 includes incandescent LED panel indicator functionality)
• Electrical specifications alignment with system voltage and current demands
• Mechanical mounting compatibility with existing panel cutout dimensions
• Compliance certifications (both parts maintain EAR99 classification and MSL 1 rating)

The TB16KKW01 introduces illumination capability not present in the KB16KKW01, which may represent either an enhancement or a functional deviation depending on application requirements.

Frequently Asked Questions (FAQ)

Q: Can TB16KKW01 directly replace KB16KKW01 in existing applications?

A: Direct replacement requires verification that the illumination feature of TB16KKW01 does not conflict with system design. The incandescent LED panel indicator adds functional capability not present in the original KB16KKW01. Mechanical mounting compatibility (panel cutout dimensions) and electrical specifications must be confirmed for the specific application.

Q: What are the critical parameters for pushbutton switch substitution?

A: Circuit configuration (SPDT), switch function (On-On), current rating (1A minimum), voltage ratings (125V AC / 30V DC), mounting type (Panel Mount, Snap-In), termination style (Solder Lug), and panel cutout dimensions (Circular 12.30mm Dia) are the primary determinants of functional compatibility.

Q: Why is the KB16KKW01 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TB16KKW01 represents an active alternative from the same manufacturer, providing continued component availability.

Q: Are both parts RoHS compliant?

A: The KB16KKW01 is confirmed ROHS3 compliant. RoHS compliance status for TB16KKW01 is not specified in the provided technical data.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management for both parts.
