ELM54753SRC LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The ELM54753SRC is a 3mm through-hole LED circuit board indicator manufactured by Bivar Inc. in the ELM5 series. This single red diffused LED features a 1.7V operating voltage, 20mA current rating, and 60mcd brightness output with a 20° viewing angle. The component is actively produced and ROHS3 compliant, designed for applications requiring compact panel-mount or circuit board indicator functionality. Substitute parts are identified when equivalent optical, electrical, and mechanical parameters are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM54753SRC are identified based on the following substitution criteria:

Primary Matching Parameters:

• Lens size: 3mm, T-1 form factor
• Lens style: Round with domed top geometry
• Color: Red spectral output
• Configuration: Single LED element
• RoHS3 compliance status
• MSL rating of 1 (Unlimited)

Secondary Compatibility Factors:

• Wavelength range within red spectrum (635nm–645nm acceptable)
• Lens type: Diffused optical characteristics
• Brightness output: Comparable millicandela rating for visibility equivalence
• Viewing angle: Application-dependent tolerance

Electrical Parameter Flexibility: Substitute parts may operate at different voltage and current ratings than the primary part, provided the substitute is suitable for the target application circuit. Voltage and current are not absolute substitution barriers but rather application-specific selection criteria.

Mounting Consideration: The ELM54753SRC is a through-hole component. Substitutes with alternative mounting types (wire leads, snap-in panel mount) are listed when optical and electrical parameters align, with the understanding that mechanical integration requires circuit design adaptation.

Engineering Selection Recommendations

ELM54753SRC Selection Criteria:

• Primary choice for through-hole PCB assembly applications
• Suitable for low-voltage circuits (1.7V operating voltage)
• Appropriate for applications requiring 60mcd brightness output
• Narrow 20° viewing angle for directed indicator applications
• ROHS3 compliant; MSL 1 rating permits standard storage and handling

5580102007F Selection Criteria:

• Alternative for applications with 5V circuit voltage availability
• Suitable for lower current consumption requirements (12mA vs. 20mA)
• Wire lead termination requires manual soldering or connector integration
• Wider 60° viewing angle for omnidirectional visibility applications
• Significantly lower brightness output (4mcd); not suitable for high-visibility requirements
• ROHS3 compliant; MSL 1 rating permits standard storage and handling

Substitution Feasibility: The 5580102007F presents optical and electrical parameter differences that require application-level evaluation. The 15-fold brightness reduction (60mcd to 4mcd) and 3-fold viewing angle increase (20° to 60°) represent distinct functional characteristics. Substitution is valid only when the target application circuit operates at 5V, accepts 12mA current draw, accommodates wire lead termination, and does not require the original brightness specification.

Frequently Asked Questions (FAQ)

Q: Can the 5580102007F directly replace the ELM54753SRC in a through-hole PCB assembly?

A: No. The ELM54753SRC is a through-hole component with leads designed for PCB insertion. The 5580102007F features 14-inch wire leads intended for manual soldering or connector-based termination. Direct PCB hole substitution is not possible without circuit board redesign or external wiring adaptation.

Q: What is the significance of the 645nm vs. 635nm wavelength difference?

A: Both wavelengths fall within the red spectrum and produce visually equivalent red color perception. The 10nm difference reflects manufacturing variation between suppliers and does not affect functional color indication in typical applications.

Q: Why is the brightness rating so different between these parts (60mcd vs. 4mcd)?

A: Brightness output is determined by LED die characteristics, lens design, and optical efficiency. The ELM54753SRC is designed for high-visibility indicator applications, while the 5580102007F is optimized for lower-power panel mount applications. Brightness selection is application-specific and cannot be overlooked during substitution evaluation.

Q: Can I use the 5580102007F in a 1.7V circuit?

A: No. The 5580102007F is rated for 5V operation. Applying 1.7V will result in insufficient LED forward voltage and no light output. Conversely, applying 5V to an ELM54753SRC rated for 1.7V will cause component failure.

Q: Are both parts suitable for industrial or automotive applications?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, indicating suitability for standard industrial storage and handling. Specific automotive or harsh-environment qualification requires verification against application-specific standards not provided in the component specifications.

Q: What does the 20° vs. 60° viewing angle difference mean for my application?

A: Viewing angle defines the cone of light emission. The ELM54753SRC with 20° produces a narrow, directed light beam suitable for front-facing indicator panels. The 5580102007F with 60° produces a wider light distribution, suitable for applications where the indicator must be visible from multiple angles or positions.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry identical MSL 1 ratings. No compliance or certification differences exist based on provided specifications. Both are actively manufactured and available for procurement.
