Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HSMH-C120 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Red wavelength indication (639nm dominant wavelength range)
• Mounting Type: Surface Mount, Right Angle configuration
• Current Rating: 20mA test current compatibility
• Voltage Range: Forward voltage within acceptable circuit design tolerance
• Viewing Angle: Minimum 150° for wide-angle indication applications
• RoHS3 Compliance: Environmental and regulatory alignment

Substitution Logic: The HSMH-C120 has two identified substitutes that maintain red LED indication functionality with surface mount right-angle mounting. Both substitutes operate at compatible test currents and maintain red wavelength specifications. Variations in millicandela rating, lens transparency, and specific package dimensions are documented to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

HSMH-H120 (Broadcom Limited): This substitute maintains the same manufacturer lineage and identical lens size (1.20mm x 0.60mm) with matching 155° viewing angle. The part is Active status, ensuring procurement availability. Forward voltage increases from 1.8V to 2.1V, requiring circuit design verification for voltage drop compatibility. Millicandela rating decreases to 7.2mcd, suitable for applications where lower brightness is acceptable. Moisture sensitivity level remains 2A (4 Weeks), maintaining equivalent handling requirements. RoHS3 compliance status is not specified in available data.

APGA1602SEC/E/KA (Kingbright): This substitute provides Active product status with significantly higher brightness at 120mcd, suitable for applications requiring enhanced visibility. Forward voltage of 2.05V falls between the main part and HSMH-H120, requiring circuit design evaluation. The component features a larger lens size (1.60mm x 0.90mm) and reduced maximum height (0.30mm), enabling compact PCB layouts. Viewing angle specification includes 150° and 120° options. Moisture sensitivity level is 3 (168 Hours), requiring extended dry storage protocols compared to the main part. RoHS3 compliance is confirmed. Package designation is 0603 (1608 Metric), differing from the main part's 2-SMD, No Lead specification.

Selection between substitutes depends on brightness requirements, circuit voltage tolerance, and PCB space constraints. Both substitutes maintain red wavelength indication and 20mA test current compatibility with the HSMH-C120.

Frequently Asked Questions (FAQ)

Q: Can HSMH-H120 be used as a direct replacement for HSMH-C120?

A: HSMH-H120 maintains the same manufacturer (Broadcom Limited), identical lens size (1.20mm x 0.60mm), and matching 155° viewing angle. The primary design consideration is the forward voltage increase from 1.8V to 2.1V, which requires circuit verification to ensure adequate current limiting and voltage headroom. Brightness reduction to 7.2mcd must be evaluated against application visibility requirements.

Q: What are the key differences between HSMH-H120 and APGA1602SEC/E/KA?

A: HSMH-H120 is a Broadcom part with lower brightness (7.2mcd) and maintains the original lens size. APGA1602SEC/E/KA is a Kingbright part with significantly higher brightness (120mcd), larger lens dimensions (1.60mm x 0.90mm), and lower profile height (0.30mm). The Kingbright part uses 0603 (1608 Metric) package designation versus the Broadcom 2-SMD, No Lead specification. Forward voltage differs slightly (2.05V vs 2.1V).

Q: Are there packaging differences that affect assembly?

A: HSMH-C120 uses 2-SMD, No Lead packaging. HSMH-H120 packaging details are not specified in available data. APGA1602SEC/E/KA uses 0603 (1608 Metric) package designation with Chip LED supplier device package. Physical dimensions vary: HSMH-C120 is 1.60mm L x 1.00mm W x 0.70mm H maximum; APGA1602SEC/E/KA is 1.60mm L x 0.90mm W x 0.30mm H maximum. PCB footprint and assembly process compatibility must be verified before implementation.

Q: Do all substitutes meet RoHS3 compliance?

A: HSMH-C120 and APGA1602SEC/E/KA are confirmed ROHS3 Compliant. HSMH-H120 RoHS3 compliance status is not specified in available data and must be verified with the manufacturer or distributor.

Q: What is the impact of moisture sensitivity level differences?

A: HSMH-C120 and HSMH-H120 both specify MSL 2A (4 Weeks), requiring storage in dry conditions with a 4-week floor life after moisture exposure. APGA1602SEC/E/KA specifies MSL 3 (168 Hours), requiring extended dry storage protocols with a 168-hour floor life. This affects component handling, storage procedures, and reflow process planning. Higher MSL ratings require more stringent moisture control during manufacturing.

Q: How does brightness rating affect circuit design?

A: HSMH-C120 provides 17mcd brightness. HSMH-H120 reduces this to 7.2mcd, suitable for indicator applications where lower visibility is acceptable. APGA1602SEC/E/KA increases brightness to 120mcd, enabling high-visibility indication in bright ambient conditions. Brightness selection depends on application requirements, viewing distance, and ambient light conditions. Current limiting resistor values may require adjustment based on brightness selection.
