Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLM2C-RCA-CWBZ0BB3 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Red
• Wavelength - Dominant: 622nm
• Package / Case: 4-PLCC
• Mounting Type: Surface Mount
• Lens Style: Round with Domed Top
• Lens Size: 2.45mm Dia
• Size / Dimension: 3.20mm L x 2.80mm W

Allowable Parameter Variations:

• Voltage - Forward (Vf): 2V to 2.1V (within typical operating range)
• Millicandela Rating: 3500mcd to 4200mcd (brightness variation acceptable for indication applications)
• Height (Max): 3.72mm to 3.86mm (within PCB assembly clearance tolerance)
• Lens Transparency: Clear or Diffused (both suitable for indication)
• Packaging Format: Cut Tape (CT) or Tape & Reel (TR) (assembly process dependent)

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

CLM2C-RCA-CYAZ0BB3 (Parametric Equivalent)

This part is the primary parametric equivalent to the CLM2C-RCA-CWBZ0BB3. It maintains identical electrical specifications (2V forward voltage, 20mA test current) and mechanical dimensions (3.20mm L x 2.80mm W, 3.86mm height). The millicandela rating increases from 3500mcd to 4200mcd, providing enhanced brightness within the same optical package. Both parts share the same base product number (CLM2C) and series designation. The CLM2C-RCA-CYAZ0BB3 carries ROHS3 compliance, representing an updated regulatory status. Packaging differs only in format (Tape & Reel versus Cut Tape), which is a procurement and assembly consideration rather than a functional limitation. This part is designated Last Time Buy, indicating similar lifecycle status to the main part.

CLM2D-RPC-CXAZ0BB3 (Similar Substitute)

This part provides functional substitution with minor parameter variations. Forward voltage increases to 2.1V, requiring circuit verification to confirm acceptable voltage drop within the application. Millicandela rating is 3700mcd, positioned between the main part and the parametric equivalent. The lens transparency is diffused rather than clear, altering the light distribution characteristics and visual appearance. Height is reduced to 3.72mm, providing improved PCB assembly clearance. This part carries Active product status, ensuring ongoing availability and supply continuity. Packaging is Tape & Reel format. The diffused lens characteristic makes this part suitable for applications where light diffusion is acceptable or preferred.

Frequently Asked Questions (FAQ)

Q: Can CLM2C-RCA-CYAZ0BB3 be used as a direct replacement for CLM2C-RCA-CWBZ0BB3?

A: Yes. Both parts share identical forward voltage (2V), test current (20mA), package type (4-PLCC), and mechanical dimensions. The millicandela rating difference (4200mcd versus 3500mcd) represents increased brightness, which is acceptable for indication applications. Packaging format differs (Tape & Reel versus Cut Tape), which affects procurement and assembly processes but not functional performance.

Q: What is the impact of the 2.1V forward voltage in CLM2D-RPC-CXAZ0BB3?

A: The 0.1V increase in forward voltage must be evaluated within the circuit design. If the application uses a current-limiting resistor, the voltage drop across the resistor will decrease by approximately 0.1V, potentially increasing LED current. Circuit simulation or testing is necessary to confirm the LED operates within acceptable current limits.

Q: How does the diffused lens in CLM2D-RPC-CXAZ0BB3 differ from the clear lens in the main part?

A: The diffused lens scatters light over a wider area, reducing peak brightness in the direct viewing direction but improving visibility from off-axis angles. The clear lens concentrates light in a narrower beam. Selection depends on the application's viewing angle requirements and desired light distribution pattern.

Q: Are all three parts RoHS compliant?

A: Yes. CLM2C-RCA-CWBZ0BB3 and CLM2D-RPC-CXAZ0BB3 carry RoHS Compliant status. CLM2C-RCA-CYAZ0BB3 carries ROHS3 Compliant status, representing an updated regulatory certification. Both certifications satisfy RoHS requirements.

Q: What is the significance of Last Time Buy status for CLM2C-RCA-CWBZ0BB3 and CLM2C-RCA-CYAZ0BB3?

A: Last Time Buy indicates the manufacturer has discontinued or will discontinue production. Existing inventory is available for purchase, but no future production is planned. CLM2D-RPC-CXAZ0BB3 carries Active status, meaning the manufacturer continues production and supply is expected to remain available long-term.

Q: Does packaging format (Cut Tape versus Tape & Reel) affect electrical performance?

A: No. Packaging format is a procurement and assembly consideration only. Cut Tape is suitable for manual or small-volume assembly. Tape & Reel is optimized for high-volume automated assembly. Electrical and optical performance is identical regardless of packaging format.

Q: Can height variation (3.72mm versus 3.86mm) affect PCB assembly?

A: The 0.14mm height difference is within typical PCB assembly tolerances and should not affect reflow soldering or component placement. The reduced height of CLM2D-RPC-CXAZ0BB3 provides additional clearance margin for applications with tight vertical space constraints.
