Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMD15-22VRVGC/TR8 are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Electrical Compatibility:

• Dual-color green and red LED configuration with independent operation
• Forward voltage ranges: Green 2.0V to 2.2V, Red 1.7V to 2.8V (compatible with standard 5V logic circuits with appropriate current limiting resistors)
• Test current of 20mA for both colors
• Millicandela ratings within acceptable brightness tolerance (6.5mcd to 25mcd range maintains functional indication capability)

Mechanical Compatibility:

• Surface mount package type (4-SMD, No Lead)
• Physical dimensions: 3.20mm L x 2.70mm W (1206 or 1210 metric equivalent packages)
• Maximum height 1.10mm to 1.30mm (maintains PCB clearance compatibility)
• Rectangle flat-top lens style with clear, colorless lens

Regulatory Compliance:

• ROHS3 compliance required
• REACH unaffected status
• EAR99 export classification

Substitute parts meeting these criteria are grouped into two categories: Active Status Alternatives (current production) and Obsolete Status Alternatives (discontinued but functionally equivalent).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Active Status Parts:

SML-LX1210SRSGC-TR (Lumex Opto/Components Inc.) is the preferred substitute for new designs and long-term procurement. This part maintains active production status, ensuring supply chain continuity. It provides 10mcd green and 15mcd red output, matching the original brightness specification within acceptable tolerance. The 1210 package footprint is mechanically compatible with the original 1206 SMD specification. Forward voltages of 2.2V green and 1.7V red are within standard logic circuit operating ranges. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements. Inventory availability of 12,026 units supports immediate procurement needs.

SML-LX1210IGC-TR (Lumex Opto/Components Inc.) serves as an alternative active-status substitute with identical mechanical compatibility and regulatory compliance. This variant provides 10mcd output for both colors, offering balanced brightness characteristics. Forward voltages of 2.2V green and 2V red maintain circuit compatibility. The higher viewing angle of 160° provides enhanced visibility compared to the original specification.

LTST-C155JCKT (Lite-On Inc.) represents an active-status alternative with superior brightness ratings (16mcd green, 25mcd red). This part maintains 1210 package compatibility and ROHS3 compliance. The lower red forward voltage of 1.8V requires verification against existing current-limiting resistor designs to prevent excessive current draw.

Secondary Recommendation - Obsolete Status Parts (Functional Equivalents):

QTLP650C74TR and QTLP650C24TR (onsemi) provide functionally equivalent alternatives with identical 1210 package dimensions and 3.20mm x 2.70mm footprint. These parts are classified as obsolete but remain available in inventory (826 and 734 units respectively). QTLP650C74TR offers 6.5mcd green and 15mcd red output with forward voltages of 2V green and 1.9V red. QTLP650C24TR provides 6.5mcd green and 4mcd red output with 2V forward voltage for both colors. Selection between these variants depends on specific brightness requirements for red indication.

QTLP600C24TR (onsemi) is not recommended as a direct substitute due to package size incompatibility. This part uses a 0606 package (1.90mm x 1.60mm), which differs from the original 1206 specification and requires PCB layout modification.

Regulatory and Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. Moisture sensitivity levels vary between MSL 1 (unlimited) and MSL 3 (168 hours), requiring adjustment to storage and handling procedures. Parts with MSL 3 rating require baking before reflow soldering if storage exceeds 168 hours at 30°C/60% relative humidity.

Frequently Asked Questions (FAQ)

Q1: Can SML-LX1210SRSGC-TR be used as a direct replacement for CMD15-22VRVGC/TR8 without PCB modification?

A: Yes. The SML-LX1210SRSGC-TR maintains identical physical dimensions (3.20mm L x 2.70mm W) and maximum height (1.10mm) as the original part. The 1210 package footprint is compatible with 1206 SMD land patterns. Forward voltage differences (2.2V green vs. 2.1V, 1.7V red vs. 2.8V) require verification of current-limiting resistor values to ensure proper LED current. The lower red forward voltage may result in higher current draw if resistor values are not adjusted.

Q2: What is the impact of forward voltage differences on circuit design?

A: Forward voltage (Vf) directly affects the voltage drop across the LED and determines the required current-limiting resistor value. The formula is: R = (Vsupply - Vf) / Iled. For example, with a 5V supply and 20mA target current, the original part requires R = (5V - 2.8V) / 20mA = 110Ω for red. The SML-LX1210SRSGC-TR with 1.7V red Vf requires R = (5V - 1.7V) / 20mA = 165Ω. Failure to adjust resistor values may cause excessive current and premature LED failure. Verify resistor calculations before implementation.

Q3: Are there package compatibility issues between 1206 and 1210 designations?

A: The 1206 and 1210 designations refer to metric package sizes. 1206 = 3.20mm x 1.60mm, 1210 = 3.20mm x 2.70mm. The CMD15-22VRVGC/TR8 uses a 1206 package, while most substitutes use 1210. The length (3.20mm) is identical, but the width differs (1.60mm vs. 2.70mm). PCB land patterns must accommodate the wider 1210 package. Verify PCB layout compatibility before component selection. The 1210 package may not fit existing 1206 footprints without modification.

Q4: What is the significance of millicandela (mcd) ratings in substitute selection?

A: Millicandela rating indicates LED brightness at the specified test current (20mA). The original part provides 10mcd green and 20mcd red. Substitutes range from 6.5mcd to 25mcd depending on the variant. Lower mcd ratings (6.5mcd) may result in reduced visibility in high-ambient-light environments. Higher mcd ratings (25mcd) provide enhanced brightness but may cause excessive brightness in low-light applications. Select substitutes with mcd ratings within ±30% of the original specification to maintain consistent visual indication performance.

Q5: How do moisture sensitivity levels (MSL) affect component handling?

A: MSL ratings define maximum storage duration at specified temperature and humidity conditions before baking is required. The original part has MSL 2 (1 Year at 30°C/60% RH). Substitutes with MSL 3 (168 hours) require baking if storage exceeds 168 hours. Baking procedure: 125°C for 24 hours in a dry oven. Failure to bake MSL 3 components before reflow soldering may cause moisture-induced failures such as delamination or solder joint cracking. Verify storage duration and implement baking procedures accordingly.

Q6: Which substitute offers the best long-term supply chain continuity?

A: SML-LX1210SRSGC-TR (Lumex) is recommended for long-term supply continuity. This part maintains active production status with 12,026 units in current inventory. Active-status parts receive ongoing manufacturing support and are less subject to discontinuation. LTST-C155JCKT (Lite-On) and SML-LX1210IGC-TR (Lumex) are alternative active-status options. Obsolete-status parts (QTLP series) should be considered only for legacy system support where new production is not anticipated.

Q7: Are there viewing angle differences between the original and substitute parts?

A: The original CMD15-22VRVGC/TR8 does not specify a viewing angle. Substitutes range from 130° to 160°. Viewing angle defines the cone of light emission; wider angles provide visibility from more oblique positions. The SML-LX1210 series offers 160° viewing angle, providing superior visibility compared to onsemi QTLP series (130° to 140°). For applications requiring wide-angle visibility (e.g., panel-mounted indicators), select substitutes with 160° viewing angle. For narrow-angle applications, 130° to 140° viewing angles are acceptable.

Q8: What compliance certifications are required for substitute parts?

A: All recommended substitutes maintain ROHS3 compliance (Restriction of Hazardous Substances Directive 3) and REACH unaffected status (Registration, Evaluation, Authorization and Restriction of Chemicals). These certifications satisfy EU environmental regulations and are required for products sold in European markets. ECCN classification (EAR99) and HTSUS code (8541.41.0000) are identical across all parts, indicating no export control restrictions. Verify compliance documentation with supplier before procurement to ensure regulatory requirements are met for target markets.
