Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5975213407F are qualified based on the following criteria:

Electrical Compatibility: Forward voltage (1.9V) and test current (20mA) must match to ensure proper circuit operation without redesign of current-limiting resistor networks.

Optical Specifications: Dominant wavelength (605nm) and diffused lens transparency must be identical to maintain color consistency and light distribution characteristics in the application.

Package Compatibility: 0603 (1608 Metric) package with surface mount configuration ensures mechanical fit on printed circuit boards without layout modifications.

Compliance Requirements: RoHS3 compliance status must be maintained for regulatory alignment.

The identified substitutes (HSML-C190 and HSML-C191 from Broadcom Limited) meet all these criteria while offering variations in millicandela rating, viewing angle, and physical height that may provide performance advantages in specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, confirming suitability for current production environments. The Broadcom HSML-C190 and HSML-C191 substitutes provide identical electrical and optical core specifications (1.9V forward voltage, 605nm dominant wavelength, 20mA test current) with enhanced luminous intensity (90mcd versus 65mcd) and wider viewing angle (170° versus 152°).

Height variations exist: the Dialight 5975213407F measures 0.70mm maximum height, while HSML-C190 reaches 0.80mm and HSML-C191 is 0.60mm. These differences require verification against specific PCB clearance and assembly constraints. Moisture sensitivity differs, with the Dialight part rated MSL 3 (168 hours) and Broadcom parts rated MSL 2A (4 weeks), affecting storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can HSML-C190 or HSML-C191 be used as direct replacements for the Dialight 5975213407F?

A: Yes, both Broadcom parts are electrically and optically compatible. They share identical forward voltage (1.9V), test current (20mA), dominant wavelength (605nm), and package format (0603). No circuit modifications are required. Physical height differences must be evaluated against PCB layout constraints.

Q: What is the significance of the higher millicandela rating in the Broadcom substitutes?

A: The Broadcom HSML-C190 and HSML-C191 deliver 90mcd compared to the Dialight part's 65mcd. This represents increased luminous intensity at the same forward voltage and test current, resulting in brighter indication at identical drive conditions. Applications requiring higher visibility benefit from this characteristic.

Q: How do viewing angle differences affect substitution?

A: The Dialight 5975213407F provides 152° viewing angle, while both Broadcom substitutes offer 170°. The wider viewing angle of the Broadcom parts allows light distribution across a larger spatial range. This is beneficial for applications requiring visibility from multiple angles but does not prevent substitution in designs optimized for the narrower angle.

Q: Are there height constraints that affect PCB assembly compatibility?

A: Yes. The Dialight part has 0.70mm maximum height, HSML-C190 has 0.80mm, and HSML-C191 has 0.60mm. Designs with tight vertical clearance requirements must account for these differences. HSML-C191 offers the lowest profile option.

Q: What is the impact of different Moisture Sensitivity Levels?

A: The Dialight 5975213407F is rated MSL 3 (168 hours), while Broadcom parts are MSL 2A (4 weeks). Lower MSL ratings require more stringent moisture control during storage and handling. Substitution requires alignment with existing component storage and assembly protocols.

Q: Do all three parts meet current regulatory requirements?

A: Yes. All parts are RoHS3 compliant and REACH unaffected, confirming compliance with current environmental and regulatory standards for production use.
