Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSF-LXH1071GD is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: Green
• Wavelength - Peak: 565nm
• Configuration: Single
• Current Rating: 20mA
• Millicandela Rating: 20mcd
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole, Right Angle
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Voltage Rating: ±0.2V tolerance
• Viewing Angle: ±20° tolerance

The SSF-LXH100MGD meets all mandatory matching parameters and falls within allowable variation ranges for voltage rating (2.2V vs. 2.1V) and viewing angle (60° vs. 80°). This part is classified as active, ensuring ongoing availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The SSF-LXH100MGD is the direct equivalent substitute for the obsolete SSF-LXH1071GD. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The SSF-LXH100MGD is classified as active, providing assured long-term availability and supply chain continuity compared to the obsolete status of the main part.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring no regulatory barriers to substitution in existing or new designs.

Electrical and Mechanical Compatibility: The substitute part maintains all critical electrical parameters (20mA current, 20mcd brightness, 565nm wavelength) and mechanical specifications (5mm T-1 3/4 through-hole right-angle mounting, diffused tinted domed lens).

Allowable Parameter Variations: The voltage rating difference (2.2V vs. 2.1V) and viewing angle reduction (60° vs. 80°) fall within acceptable engineering tolerances for circuit board indicator applications. The 0.1V increase in forward voltage requires no circuit redesign for standard current-limiting resistor configurations. The 20° reduction in viewing angle maintains adequate visibility for typical indicator applications.

Moisture and Environmental Ratings: Identical MSL 1 (Unlimited) classification ensures equivalent performance in storage, handling, and operational environments.

Frequently Asked Questions (FAQ)

Q: Can SSF-LXH100MGD directly replace SSF-LXH1071GD in existing designs?

A: Yes. The SSF-LXH100MGD is a direct substitute meeting all mandatory electrical and mechanical parameters. The 0.1V voltage increase and 20° viewing angle reduction do not require circuit modifications for standard indicator applications.

Q: What is the primary reason for substitution?

A: The SSF-LXH1071GD is classified as obsolete. The SSF-LXH100MGD is an active product from the same manufacturer, ensuring supply availability and long-term support.

Q: Are there any compliance concerns with this substitution?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. No regulatory barriers exist for this substitution.

Q: How does the 60° viewing angle of the substitute compare to the 80° of the main part?

A: The 20° reduction in viewing angle remains within acceptable tolerance for circuit board indicator applications. Applications requiring the full 80° viewing angle should be evaluated individually.

Q: Is the 2.2V forward voltage of the substitute compatible with existing circuits designed for 2.1V?

A: Yes. The 0.1V difference is within standard tolerance for LED circuit design. Existing current-limiting resistor values will function correctly with the substitute part.

Q: What is the packaging difference between these parts?

A: The SSF-LXH1071GD is listed with standard packaging, while the SSF-LXH100MGD is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: Are both parts RoHS compliant?

A: Yes. Both SSF-LXH1071GD and SSF-LXH100MGD are ROHS3 compliant and REACH unaffected.
