Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB-A100SRW is determined by the following critical parameters:

Mechanical Compatibility Parameters:

• Lens size: 8.89mm x 3.81mm (must match exactly for PCB layout compatibility)
• Lens style: Rectangle with Flat Top (physical form factor requirement)
• Mounting type: Through Hole (assembly process compatibility)
• Configuration: Bar - Single, DIP (electrical interface requirement)

Optical Parameters:

• Color: Red (visual indication function)
• Lens type: Diffused, White (light distribution characteristic)

Electrical Parameters:

• Voltage rating and current specifications must fall within acceptable operating ranges for the target application circuit

Compliance Parameters:

• RoHS3 compliance status
• REACH compliance status
• Moisture Sensitivity Level classification

The KB-A100SURKW qualifies as a substitute based on matching mechanical form factor, optical characteristics, mounting methodology, and regulatory compliance requirements. Electrical parameter variations (voltage and current) represent design differences within the KB-A100 base product family.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: KB-A100SURKW

The KB-A100SURKW is the manufacturer-recommended substitute for the obsolete KB-A100SRW. Both components share identical mechanical form factors, mounting methodologies, and regulatory compliance certifications. The KB-A100SURKW maintains active product status, ensuring ongoing availability and supply chain reliability.

Compliance Verification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for new designs and production environments.

Electrical Parameter Considerations: The KB-A100SURKW operates at 1.95V with a maximum current rating of 185mA, compared to the KB-A100SRW specification of 1.85V at 30mA. The substitute part exhibits higher current capacity and marginally elevated voltage specification. Circuit design must accommodate these electrical characteristics through appropriate current-limiting resistor selection and power supply voltage verification.

Optical Characteristics: Peak wavelength differs between parts (645nm for KB-A100SURKW versus 660nm for KB-A100SRW). Both wavelengths fall within the red spectrum range. The KB-A100SURKW provides 75mcd brightness compared to 100mcd for the original part. Visual indication performance remains suitable for standard circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the KB-A100SURKW be used as a direct replacement for KB-A100SRW in existing PCB designs?

A: Mechanical and mounting compatibility is confirmed. The identical lens size (8.89mm x 3.81mm), rectangular flat-top profile, and through-hole mounting type ensure physical interchangeability. Circuit design review is required to verify that the higher current rating (185mA) and elevated voltage specification (1.95V) are compatible with existing current-limiting resistor values and power supply voltage levels.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), electrical specifications (voltage and current ratings), optical brightness (100mcd versus 75mcd), and peak wavelength (660nm versus 645nm). Mechanical form factor, lens type, mounting methodology, and regulatory compliance are identical.

Q: Are there any packaging differences between KB-A100SRW and KB-A100SURKW?

A: Yes. The KB-A100SRW is supplied in bulk packaging, while the KB-A100SURKW is supplied in tube packaging. This difference affects handling, storage, and component counting procedures but does not impact electrical or mechanical performance.

Q: Does the wavelength difference (660nm to 645nm) affect visual indication performance?

A: Both wavelengths are within the red spectrum range. The shift from 660nm to 645nm represents a minor spectral adjustment. Visual perception of red indication remains consistent for standard circuit board indicator applications. Specific color-matching requirements for specialized applications should be evaluated against actual application parameters.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both KB-A100SRW and KB-A100SURKW maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for manufacturing and distribution in regulated markets.

Q: What is the Moisture Sensitivity Level for these components?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
