Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMDA5CG7D1Z is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2.1V nominal operation
• Test current: 20mA standard
• Peak wavelength: 560nm green spectrum

Optical Characteristics:

• Color: Green
• Lens transparency: Diffused
• Lens size: 1.40mm x 1.25mm rectangular profile
• Viewing angle: 150° or greater

Mechanical & Package Compatibility:

• Mounting type: Surface mount
• Package format: 0805 (2012 Metric) standard footprint
• Dimensions: 2.00mm L x 1.25mm W compatible
• Height: ≤0.90mm maximum

Compliance & Environmental:

• RoHS3 compliance required
• MSL rating: 2A or 3 acceptable for standard assembly processes
• REACH unaffected status

Substitute parts are grouped into two categories: Direct Equivalents (matching mounting orientation and electrical parameters) and Similar Alternatives (compatible electrical and optical performance with standard surface mount orientation).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Preferred Substitution:

The 7012X5 (VCC BrightChips™ series) is the primary direct equivalent for the CMDA5CG7D1Z. Both components share identical electrical parameters (2.1V forward voltage, 20mA test current, 560nm peak wavelength, 6.4mcd brightness) and are manufactured by the same supplier. The 7012X5 is active in production with 46,531 units in stock, ensuring procurement continuity. The transition from right-angle to standard surface mount orientation requires PCB layout modification but maintains full electrical compatibility. Both parts are ROHS3 compliant and REACH unaffected.

Compatible Alternatives - Diffused Lens Matching:

The HSME-C170 (Broadcom) provides the closest optical match with identical lens size (1.40mm x 1.25mm), diffused transparency, and matching forward voltage (2.1V). This part offers superior brightness (50mcd versus 6.4mcd) and wider viewing angle (170° versus 150°), with improved MSL rating (2A versus 4). The HSME-C170 is active with 21,400 units available.

The HSMM-C170 and HSMQ-C170 (Broadcom) are diffused lens alternatives with identical lens size and mounting type. These parts operate at higher forward voltages (3.3V and 3.4V respectively) and deliver significantly higher brightness levels (120mcd and 145mcd). Selection of these parts requires circuit redesign to accommodate the elevated voltage requirements.

Alternative with Lens Transparency Variation:

The APT2012SGC (Kingbright) provides a clear lens alternative with compatible electrical parameters (2.2V forward voltage, 20mA test current, 565nm peak wavelength). This part is suitable for applications where diffused lens characteristics are not critical. The APT2012SGC has 3,191 units in stock and is active in production.

Selection Criteria:

• For direct replacement with minimal design modification: 7012X5
• For enhanced brightness with matching voltage: HSME-C170
• For applications requiring higher brightness with circuit redesign: HSMM-C170 or HSMQ-C170
• For clear lens applications: APT2012SGC

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q1: Can the 7012X5 be used as a direct drop-in replacement for the CMDA5CG7D1Z?

A: The 7012X5 is electrically equivalent but requires PCB layout modification. The CMDA5CG7D1Z features right-angle mounting (2-SMD, No Lead package), while the 7012X5 uses standard 0805 (2012 Metric) surface mount orientation. Footprint redesign is necessary, but electrical performance is identical.

Q2: What is the primary difference between the HSME-C170 and HSMM-C170?

A: Both are Broadcom diffused lens green LEDs with identical lens size (1.40mm x 1.25mm) and mounting type. The HSME-C170 operates at 2.1V (matching the original part) with 50mcd brightness, while the HSMM-C170 operates at 3.3V with 120mcd brightness. Forward voltage selection determines circuit compatibility.

Q3: Why do some substitute parts have higher millicandela ratings?

A: Millicandela rating reflects LED brightness output. Higher ratings (HSMQ-C170 at 145mcd versus CMDA5CG7D1Z at 6.4mcd) indicate greater light intensity. Selection depends on application requirements; higher brightness may require current-limiting resistor adjustment in the circuit.

Q4: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts (7012X5, APT2012SGC, HSME-C170, HSMM-C170, HSMQ-C170) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q5: What does MSL rating mean, and why does it vary among substitutes?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions (30°C, 85% relative humidity) before soldering. The CMDA5CG7D1Z has MSL 4 (72 hours), while most substitutes have MSL 2A or 3 (4 weeks to 168 hours). Lower MSL numbers indicate better moisture tolerance and are preferred for standard assembly processes.

Q6: Can the APT2012SGC replace the CMDA5CG7D1Z in all applications?

A: The APT2012SGC is electrically compatible (2.2V forward voltage, 20mA test current) but features a clear lens instead of diffused. Applications requiring diffused light distribution should use HSME-C170, HSMM-C170, or HSMQ-C170 instead.

Q7: What is the inventory status of substitute parts?

A: 7012X5 has 46,531 units in stock; HSME-C170 has 21,400 units; HSMM-C170 has 24,607 units; HSMQ-C170 has 15,540 units; APT2012SGC has 3,191 units. All parts are currently available for procurement.

Q8: Do substitute parts require circuit modifications?

A: The 7012X5 and HSME-C170 require only PCB layout changes due to package format differences. The HSMM-C170 and HSMQ-C170 require circuit redesign to accommodate 3.3V and 3.4V forward voltages respectively. The APT2012SGC requires only layout modification.
