Is there a pin-compatible replacement for NCD1615RG1?

No direct pin-for-pin replacement has been identified. While XL-1615SURSYGC shares the same package and pinout, its different electrical characteristics for the green LED mean it is not a drop-in replacement and requires circuit review.

What risks should I check before replacing NCD1615RG1?

Key risks include: 1) Electrical mismatch: Ensure the replacement's forward voltage is compatible with your driver circuit. 2) Color difference: Verify the replacement's wavelength meets visual requirements. 3) Pinout: Confirm the replacement is also common cathode.

NCD1615RG1 Alternatives, Datasheet & Cross Reference | Ningbo Songle Relay Co., Ltd.

NCD1615RG1 is a dual-color Red/Green LED in a 1615 surface-mount package. Finding a replacement requires matching the common cathode configuration, package size, and forward voltage characteristics for both colors.

AI replacement insight

Electrical riskhigh

Green LED forward voltage mismatch requires resistor change.

Package risklow

Package and pinout configuration are compatible.

Can it be replaced directly?

No direct, drop-in replacement for NCD1615RG1 was found. The closest candidate, XL-1615SURSYGC, requires circuit modification.

Best replacement path

Use XL-1615SURSYGC as a functional alternative, but redesign the series resistor for the green LED channel.

Main risk

The primary risk is electrical incompatibility due to a significant forward voltage difference in the green LED, which could lead to overcurrent and damage if not addressed.

Recommended alternatives

A functional alternative in the same 1615 package, but requires changing the series resistor for the green LED.
