Engineering Selection Recommendations

CLM2C-ACA-CYBA0343 is the primary parametric equivalent. It maintains identical electrical characteristics (2V, 20mA, 5325mcd) and physical dimensions as the CLM2C-ACA-CYBA0253. Both parts share Last Time Buy status. The CLM2C-ACA-CYBA0343 offers higher inventory availability (3054 pcs vs 1164 pcs) and ROHS3 compliance, providing superior long-term compliance positioning.

CLM2D-APC-CXBZ0253 serves as a functional substitute for applications where diffused lens characteristics are acceptable. This part maintains electrical compatibility (2V, 20mA, 590nm) and identical package footprint. The diffused lens reduces millicandela output to 3920mcd and introduces a white lens color. The CLM2D-APC-CXBZ0253 carries Active product status, ensuring continued availability. Height differential (3.72mm vs 3.86mm) is within typical PCB assembly tolerances.

Selection between substitutes depends on optical performance requirements and product lifecycle strategy. For direct replacement with identical optical output, CLM2C-ACA-CYBA0343 is specified. For applications tolerating reduced brightness with diffused light distribution, CLM2D-APC-CXBZ0253 provides long-term supply continuity through Active status.

Frequently Asked Questions (FAQ)

Q: Can CLM2D-APC-CXBZ0253 directly replace CLM2C-ACA-CYBA0253 in existing designs?

A: Electrical compatibility is confirmed (2V, 20mA, 590nm amber). Physical footprint is identical (3.20mm L x 2.80mm W, 4-PLCC package). The primary difference is optical: CLM2D-APC-CXBZ0253 features a diffused white lens reducing output to 3920mcd versus 5325mcd. Applications requiring identical brightness must use CLM2C-ACA-CYBA0343. Applications tolerating reduced brightness with diffused light distribution can use CLM2D-APC-CXBZ0253.

Q: What is the height difference between substitutes?

A: CLM2C-ACA-CYBA0253 and CLM2C-ACA-CYBA0343 both measure 3.86mm maximum height. CLM2D-APC-CXBZ0253 measures 3.72mm maximum height. This 0.14mm difference is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: Why is CLM2C-ACA-CYBA0343 recommended over the main part?

A: CLM2C-ACA-CYBA0343 is parametrically identical to CLM2C-ACA-CYBA0253 while offering higher inventory (3054 pcs vs 1164 pcs) and ROHS3 compliance versus RoHS compliance. Both carry Last Time Buy status, but CLM2C-ACA-CYBA0343 provides superior availability and regulatory positioning.

Q: Are all substitutes RoHS compliant?

A: Yes. CLM2C-ACA-CYBA0253 and CLM2D-APC-CXBZ0253 are RoHS Compliant. CLM2C-ACA-CYBA0343 is ROHS3 Compliant. All parts meet REACH Unaffected status and carry identical Moisture Sensitivity Level (5A, 24 Hours).

Q: What is the viewing angle difference?

A: CLM2C-ACA-CYBA0253 and CLM2C-ACA-CYBA0343 do not specify viewing angle. CLM2D-APC-CXBZ0253 specifies 30° viewing angle due to diffused lens design. This wider distribution angle is characteristic of diffused lens variants.
