Substitute Part Grouping Explanation

Substitution eligibility for the 4301F25/27 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Color configuration: Green and Yellow bidirectional operation
• Lens size and style: 3mm T-1 diffused round with domed top
• Forward voltage: 2.1V for both green and yellow channels
• Test current: 20mA for both channels
• Luminous intensity: 12.6mcd green and 8.7mcd yellow
• Wavelength specifications: 569nm dominant green, 588nm dominant yellow
• Mounting type: Through-hole radial configuration
• Viewing angle: 80°
• Compliance: ROHS3 compliant

The Lite-On Inc. LTL-14CDJ meets all mandatory matching criteria and qualifies as a direct functional equivalent. This part maintains identical electrical performance, optical characteristics, and mechanical form factor while offering active product status and improved supply availability.

Engineering Selection Recommendations

The LTL-14CDJ from Lite-On Inc. is the qualified substitute for the obsolete 4301F25/27. Selection rationale is based on the following engineering factors:

Product Status Consideration: The 4301F25/27 carries obsolete classification, creating supply risk for new production and long-term support. The LTL-14CDJ maintains active product status, ensuring continued availability and manufacturer support.

Compliance Equivalence: Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements for current manufacturing standards.

Electrical and Optical Equivalence: Complete parameter matching across forward voltage, test current, luminous intensity, and wavelength specifications ensures direct functional replacement without circuit modification or performance degradation.

Mechanical Compatibility: Identical through-hole radial mounting configuration, 3mm T-1 package dimensions, and diffused lens characteristics enable direct PCB layout compatibility.

Supply Chain Advantage: The LTL-14CDJ demonstrates superior inventory availability (965 Pcs versus 684 Pcs), supporting production continuity and reducing procurement lead time risk.

Frequently Asked Questions (FAQ)

Q: Can the LTL-14CDJ be used as a direct replacement for the 4301F25/27 without circuit modifications?

A: Yes. The LTL-14CDJ is electrically and mechanically equivalent across all critical parameters. Forward voltage, test current, luminous intensity, and wavelength specifications are identical. No circuit redesign is required.

Q: What is the primary reason for substitution?

A: The 4301F25/27 is classified as obsolete. The LTL-14CDJ provides equivalent functionality with active product status, ensuring long-term supply availability and manufacturer support.

Q: Are there any differences in mounting or PCB layout requirements?

A: No. Both parts use identical through-hole radial mounting configuration with 3mm T-1 package dimensions. Existing PCB layouts require no modification.

Q: How do the lens characteristics compare?

A: Both parts feature 3mm T-1 diffused round lenses with domed tops, identical viewing angles of 80°, and white lens color. Optical performance is equivalent.

Q: What compliance certifications apply to the substitute part?

A: The LTL-14CDJ maintains ROHS3 compliance, meeting current environmental and regulatory standards equivalent to the original part.

Q: Is there a difference in moisture sensitivity specifications?

A: The 4301F25/27 specifies MSL 2 (1 Year), while the LTL-14CDJ specifies MSL 2A (4 Weeks). Both classifications fall within MSL 2 category. Storage and handling procedures should follow the more stringent MSL 2A requirement for the substitute part.

Q: Can the LTL-14CDJ support the same current and voltage operating conditions?

A: Yes. Both parts operate at 2.1V forward voltage with 20mA test current for both green and yellow channels. Operating parameters are fully equivalent.
