Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5611201070 is determined by the following critical parameters:

• Color: Yellow (583nm peak wavelength)
• Configuration: Single LED
• Current Rating: 2mA
• Voltage Rating: 1.9V
• Millicandela Rating: 1.8mcd
• Viewing Angle: 50°
• Lens Type: Diffused
• Mounting Type: Through Hole

The substitute part 5611201070F maintains all critical electrical and optical parameters. While the lens size specification differs in the provided data, both parts belong to the same Dialight 561 series and share identical functional characteristics for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5611201070F is the designated substitute for the obsolete 5611201070. Both parts maintain identical electrical specifications (1.9V, 2mA) and optical characteristics (583nm yellow, 1.8mcd, 50° viewing angle, diffused lens). The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The 5611201070F achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement may be required for applications subject to environmental regulations. Both parts maintain unlimited moisture sensitivity rating (MSL 1) and REACH unaffected status.

For new designs or production requiring regulatory compliance, the 5611201070F is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part satisfies the functional requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5611201070F directly replace the 5611201070 in existing circuit designs?

A: Yes. Both parts share identical electrical ratings (1.9V, 2mA), optical output (1.8mcd at 583nm), and through-hole mounting configuration. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The original 5611201070 is classified as obsolete. The 5611201070F maintains all functional specifications while offering active product status and improved RoHS compliance.

Q: Are there packaging differences between these parts?

A: The main part is listed with "-" packaging designation, while the substitute is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the 5611201070 and 5611201070F carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and environmental consideration, not a functional electrical parameter. The 5611201070F's ROHS3 compliance provides regulatory advantage over the non-compliant original part. Compliance requirements depend on your application's regulatory environment.

Q: Are the optical characteristics identical between both parts?

A: Yes. Both parts deliver 1.8mcd brightness at 583nm peak wavelength with a 50° viewing angle and diffused lens type, ensuring equivalent visual performance in circuit board indicator applications.
