Key Parameters

Substitute Part Grouping Explanation

The MTE4600P-C qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Forward current rating (150mA maximum) is identical, ensuring compatible circuit operation without redesign. Forward voltage (2.8V typical) matches exactly, maintaining consistent power supply requirements. Viewing angle (10°) is preserved, sustaining optical performance characteristics. Operating temperature range (-40°C to 100°C) is identical, confirming thermal compatibility across all specified environments. Through-hole mounting type remains unchanged, allowing direct PCB footprint compatibility.

The wavelength specification differs slightly (447nm versus 450nm), representing a 3nm variation within the blue spectrum. Both parts maintain TO-18 metal can packaging with identical mechanical form factors. RoHS compliance and MSL rating (1 - Unlimited) are consistent across both parts.

Parameter Comparison

Engineering Selection Recommendations

The MTE4600P-C is the designated substitute for MTE4600P applications. Selection is based on:

Electrical parameter alignment: Forward current, voltage, and viewing angle specifications are identical, eliminating circuit redesign requirements. Thermal compatibility across the full -40°C to 100°C operating range is maintained. Regulatory compliance: Both parts carry RoHS certification and identical MSL ratings, satisfying compliance requirements for regulated industries. Product status: MTE4600P-C maintains active product status with current inventory availability (783 Pcs), whereas MTE4600P is discontinued. Mechanical compatibility: TO-18 metal can packaging ensures direct PCB footprint compatibility without layout modifications.

The 3nm wavelength variation (447nm versus 450nm) falls within acceptable tolerances for general indicator applications where precise wavelength specification is not critical to system function.

Frequently Asked Questions (FAQ)

Q: Can MTE4600P-C directly replace MTE4600P without circuit modifications?

A: Yes. Electrical parameters (forward current, voltage, viewing angle) and operating temperature range are identical. Direct substitution is possible without circuit redesign.

Q: What is the significance of the 3nm wavelength difference (450nm to 447nm)?

A: Both wavelengths fall within the blue spectrum region. The 3nm variation represents approximately 0.7% deviation and is typically imperceptible in visual indicator applications. Applications requiring precise wavelength specification should evaluate this difference against system requirements.

Q: Are the TO-18-3 and TO-18-2 packages mechanically compatible?

A: Both are TO-18 metal can variants with identical mechanical form factors and through-hole mounting characteristics. PCB footprints and lead spacing are compatible.

Q: What is the inventory status for substitution?

A: MTE4600P is discontinued at DiGi Electronics with 1084 Pcs listed as new original stock. MTE4600P-C is active with 783 Pcs available. Availability should be confirmed with current distributors.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are RoHS compliant with identical MSL ratings (1 - Unlimited) and ECCN classification (EAR99).
