Substitute Part Grouping Explanation

Substitute parts for the HLMPQ155AGR are selected based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Mounting Type: Surface Mount (2-SMD, Gull Wing package required)
Color: Red LED indication
Lens Transparency: Clear
Wavelength Range: 635nm–660nm peak wavelength
Voltage - Forward (Vf): 1.6V–2.0V typical operating range
Viewing Angle: 25°–28° (narrow viewing angle applications)
Physical Dimensions: 2.20mm L x 2.10mm W footprint compatibility
Height (Max): 2.88mm–2.92mm clearance compatibility

Substitution Logic: Substitute parts must maintain surface mount gull wing packaging with clear lens red LEDs operating within the specified voltage and wavelength parameters. Parts with diffused lenses or significantly different viewing angles are included where forward voltage and wavelength compatibility exist, as these represent functional alternatives for applications where lens transparency is not critical. Through-hole and alternative lead configurations are excluded from primary substitutes due to mounting incompatibility.

Engineering Selection Recommendations

Primary Substitutes (Gull Wing Configuration):

CMD95-21SRC/TR7 and HLMP-Q105-P0011 are the preferred active substitutes for the HLMPQ155AGR. Both maintain identical footprint dimensions (2.20mm L x 2.10mm W), gull wing packaging, clear lens configuration, and narrow viewing angles (25°–28°). CMD95-21SRC/TR7 operates at 1.7V forward voltage with 100mcd luminous intensity and 660nm peak wavelength, providing the closest spectral match. HLMP-Q105-P0011 operates at 1.8V with 200mcd and 645nm peak wavelength. Both are ROHS3 compliant and actively manufactured.

Secondary Substitutes (Alternative Lead Configurations):

HLMP-6305-L0031 provides Z-Bend lead configuration as an alternative to gull wing mounting. This part maintains 1.8V forward voltage, 40mcd luminous intensity, 635nm peak wavelength, and identical physical dimensions. The Z-Bend configuration accommodates applications where alternative lead geometry is acceptable.

Voltage Tolerance Consideration:

CMD95-21VRC/TR7 operates at 2.0V forward voltage, representing the upper limit of acceptable forward voltage deviation. This part is suitable only for applications where circuit design accommodates the 0.4V increase from the original 1.6V specification.

Compliance Status:

All active substitute parts are ROHS3 compliant and REACH unaffected. The original HLMPQ155AGR carries obsolete status; all recommended substitutes are actively manufactured and stocked.

Frequently Asked Questions (FAQ)

Q: Can CMD95-21SRC/TR7 be used as a direct replacement for HLMPQ155AGR?

A: CMD95-21SRC/TR7 is functionally compatible as a direct replacement. Both parts share identical footprint dimensions (2.20mm L x 2.10mm W), gull wing packaging, clear lens configuration, and 25° viewing angle. Forward voltage increases from 1.6V to 1.7V, and luminous intensity increases from 4mcd to 100mcd. Circuit design must accommodate these parameter changes.

Q: What is the difference between gull wing and Z-Bend lead configurations?

A: Gull wing leads extend horizontally from the component body, suitable for standard surface mount assembly on flat PCBs. Z-Bend leads feature a bent configuration that accommodates specific PCB layout requirements. HLMP-6305-L0031 provides Z-Bend configuration while maintaining electrical compatibility with the original part.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed (CMD95-21SRC/TR7, CMD95-21VRC/TR7, HLMP-6305-L0011, HLMP-6305-L0031, HLMP-Q105-P0011) are ROHS3 compliant. The original HLMPQ155AGR does not specify RoHS status.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The original HLMPQ155AGR carries MSL 1 (unlimited shelf life). Substitute parts carry MSL 2, 2A, or 3 ratings, indicating moisture sensitivity requiring controlled storage conditions. MSL 2 requires 1-year shelf life at specified humidity; MSL 2A requires 4-week shelf life; MSL 3 requires 168-hour shelf life. Storage and handling procedures must comply with the substitute part's MSL rating.

Q: Can HLMP-Q105-P0011 replace HLMPQ155AGR in high-brightness applications?

A: HLMP-Q105-P0011 operates at 200mcd luminous intensity compared to the original 4mcd specification. This 50-fold increase in brightness makes it suitable for applications requiring higher visibility. Forward voltage increases from 1.6V to 1.8V, and peak wavelength shifts from 660nm to 645nm. Circuit design must accommodate these changes.

Q: What are the physical dimension tolerances for PCB footprint compatibility?

A: The original HLMPQ155AGR measures 2.20mm L x 2.10mm W with 2.92mm maximum height. Substitute parts maintain compatible dimensions within 0.12mm variation (2.08mm–2.21mm length, 2.10mm–2.21mm width, 2.88mm–2.92mm height). Standard PCB design tolerances accommodate these variations.

Q: Is CMD95-21VRC/TR7 suitable for direct replacement?

A: CMD95-21VRC/TR7 is functionally compatible but operates at 2.0V forward voltage, representing a 0.4V increase from the original 1.6V specification. This part is suitable only for applications where circuit design accommodates the higher forward voltage. Peak wavelength shifts to 640nm, and luminous intensity is 25mcd.
