Parameter Comparison

Engineering Selection Recommendations

Both 5660406F and 5660407F are direct functional equivalents to the obsolete 5660406. Selection between these substitutes should be based on the following factors:

Product Status: Both substitute parts carry Active product status, ensuring long-term availability and continued manufacturer support, unlike the obsolete main part.

Compliance Certifications: Both substitutes are ROHS3 compliant, providing improved environmental compliance compared to the non-compliant main part. Both maintain REACH Unaffected status and identical ECCN and HTSUS classifications.

Inventory Availability: 5660406F offers 2200 pieces in stock, while 5660407F provides 1408 pieces. Selection may depend on procurement volume requirements and supply chain considerations.

Packaging: Both substitutes are supplied in bulk packaging, consistent with standard component distribution practices.

Frequently Asked Questions (FAQ)

Q: Can 5660406F and 5660407F be used interchangeably with 5660406?

A: Yes. Both parts maintain identical electrical specifications (2V, 20mA), optical characteristics (635nm peak wavelength, 7.4mcd, 140° viewing angle), and physical form factor (through-hole, right-angle, rectangle flat-top lens). All critical parameters for circuit board integration are equivalent.

Q: What is the primary reason to transition from 5660406 to a substitute part?

A: The 5660406 is classified as obsolete. The substitute parts 5660406F and 5660407F are active products with guaranteed manufacturer support and availability. Additionally, the substitutes offer improved RoHS3 compliance.

Q: Are there packaging differences between the main part and substitutes?

A: The main part 5660406 has unspecified packaging, while both substitutes 5660406F and 5660407F are supplied in bulk packaging. This difference does not affect electrical or mechanical compatibility.

Q: Do the substitute parts require any circuit design modifications?

A: No. The substitute parts maintain identical voltage ratings, current specifications, and mounting configurations. Direct board-level substitution is possible without design changes.

Q: How do compliance certifications differ?

A: The main part 5660406 is RoHS non-compliant. Both substitutes 5660406F and 5660407F are ROHS3 compliant, meeting current environmental regulations. REACH and trade classification status remain unchanged across all three parts.
