SLA560EC4T3F Equivalent & Substitute Parts

Part Overview

The SLA560EC4T3F is a blue-green 525nm LED indication component manufactured by Rohm Semiconductor, designed for through-hole mounting applications. This part features a 5mm T-1 3/4 lens with 1500mcd brightness rating and 3.2V forward voltage. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLA560EC4T3F is determined by the following critical parameters:

• Mounting Type: Through Hole (radial configuration)
• Lens Size: 5mm, T-1 3/4 form factor
• Voltage - Forward (Vf): 3.2V nominal operation
• Current - Test: 20mA standard test current
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Wavelength Range: 525nm dominant wavelength (blue-green to green spectrum)
• RoHS Compliance: ROHS3 Compliant
• Regulatory Status: REACH Unaffected, EAR99 classification

The substitute parts listed maintain compatibility across these core parameters while accommodating minor variations in brightness rating (millicandela), forward voltage tolerance, and viewing angle within acceptable operational ranges for LED indication applications.

Engineering Selection Recommendations

SLA560EN4T (MFR Recommended Substitute)

This Rohm Semiconductor part is the manufacturer-recommended replacement. It maintains active product status and ROHS3 compliance. However, the 3mm lens size represents a significant form factor change from the original 5mm T-1 3/4 specification. This substitute is suitable only for applications where PCB layout and mechanical clearance can accommodate the smaller lens diameter.

SLA560EN4T3F (Similar Substitute)

This active Rohm Semiconductor part maintains the 5mm lens size and T-1 3/4 form factor of the original component. Forward voltage (3.2V) and test current (20mA) match the main part specifications. The dominant wavelength (523nm) remains within the green spectrum range. Brightness rating increases to 3000mcd. ROHS3 compliance and regulatory status are maintained. This part provides the closest mechanical and electrical compatibility for direct substitution.

LTL2T3TGK6 (Similar Substitute)

This Lite-On Inc. part maintains the 5mm T-1 3/4 form factor, clear lens transparency, and 20mA test current. Dominant wavelength (525nm) matches the original specification. Forward voltage increases to 4.6V, requiring circuit verification for voltage-sensitive applications. Brightness rating increases to 4500mcd. Viewing angle narrows to 30° compared to the original 40°. ROHS3 compliance and regulatory status are maintained. Height increases to 8.70mm, requiring mechanical clearance verification.

Frequently Asked Questions (FAQ)

Q: Can SLA560EN4T replace SLA560EC4T3F directly?

A: SLA560EN4T is the manufacturer-recommended substitute but features a 3mm lens size versus the original 5mm T-1 3/4 specification. Direct PCB mounting compatibility requires design modification. For form-factor-compatible substitution, SLA560EN4T3F or LTL2T3TGK6 are preferred.

Q: What are the key differences between SLA560EN4T3F and LTL2T3TGK6?

A: Both maintain the 5mm T-1 3/4 form factor and 20mA test current. SLA560EN4T3F matches the original 3.2V forward voltage exactly, while LTL2T3TGK6 operates at 4.6V. LTL2T3TGK6 provides higher brightness (4500mcd versus 3000mcd) but narrower viewing angle (30° versus unspecified for SLA560EN4T3F). Height differs by 1.0mm maximum.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original SLA560EC4T3F.

Q: Does forward voltage variation affect circuit compatibility?

A: Forward voltage differences must be evaluated against circuit design specifications. SLA560EN4T3F maintains 3.2V matching the original part. LTL2T3TGK6 operates at 4.6V, requiring verification that series resistor values and power supply specifications accommodate the increased voltage drop.

Q: What is the impact of brightness rating differences?

A: SLA560EN4T3F (3000mcd) and LTL2T3TGK6 (4500mcd) provide increased brightness compared to the original 1500mcd rating. For indication applications with fixed current limiting, higher brightness may require circuit adjustment to prevent over-illumination or reduce component lifespan.

Q: Are there mechanical clearance concerns with substitute parts?

A: LTL2T3TGK6 maximum height is 8.70mm versus the original 7.70mm, a 1.0mm increase. PCB layout and enclosure design must accommodate this variation. SLA560EN4T3F height specification is not provided; verification with the manufacturer is recommended before final design release.
