Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTL-42M1NHDP1 are identified based on the following critical parameters that determine functional equivalence:

• Lens size and style (3mm, T-1, round with domed top)
• Dual-level configuration (2 High)
• Color and wavelength (Green, 565nm peak)
• Voltage rating (2.1V)
• Millicandela rating (12.6mcd)
• Viewing angle (60°)
• Lens type (Diffused, Tinted)

Two substitute parts meet these core electrical and mechanical criteria: LTL-42M4NH106 (Lite-On Inc., active status) and 5530122200F (Dialight, active status). Both maintain identical optical and electrical performance specifications within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

LTL-42M4NH106 is the primary substitute for the obsolete LTL-42M1NHDP1. Both components are manufactured by Lite-On Inc., share identical electrical and optical specifications, and the substitute maintains active product status with ROHS3 compliance. This part provides direct functional equivalence with improved supply chain availability.

5530122200F (Dialight) serves as an alternative substitute with identical optical performance and electrical ratings. This part operates at reduced current (20mA versus 120mA), features through-hole right-angle mounting configuration, and offers superior moisture sensitivity characteristics (MSL 1 versus MSL 2A). Selection of this part requires verification of circuit design compatibility with the lower current specification and mounting orientation requirements.

Frequently Asked Questions (FAQ)

Q: Can LTL-42M4NH106 be used as a direct replacement for LTL-42M1NHDP1?

A: Yes. Both parts share identical lens size, configuration, color, wavelength, voltage rating, current, millicandela rating, viewing angle, and lens type specifications. The primary difference is product status: LTL-42M4NH106 is active while LTL-42M1NHDP1 is obsolete.

Q: What is the key difference between LTL-42M4NH106 and 5530122200F?

A: The primary electrical difference is current rating: LTL-42M4NH106 operates at 120mA while 5530122200F operates at 20mA. Additionally, 5530122200F features through-hole right-angle mounting, whereas mounting type is not specified for LTL-42M4NH106. Moisture sensitivity also differs: LTL-42M4NH106 is MSL 2A (4 Weeks) while 5530122200F is MSL 1 (Unlimited).

Q: Can 5530122200F be used in applications designed for 120mA operation?

A: No. The 5530122200F is rated for 20mA operation. Circuit design compatibility must be verified before substitution, as the lower current rating may affect circuit performance and brightness output.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both LTL-42M4NH106 and 5530122200F are ROHS3 compliant.

Q: What packaging formats are available for these substitute parts?

A: LTL-42M4NH106 is supplied in Tray packaging. 5530122200F is supplied in Bulk packaging.
