Substitute Part Grouping Explanation

Substitution of the NJM78LR05DU-TE1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Output configuration (Positive)
• Output type (Fixed)
• Output voltage (5V)
• Maximum output current (100mA)
• Input voltage rating (18V maximum)
• Quiescent current (3.4 mA)
• PSRR specification (79dB at 120Hz)
• Control features (Reset function)
• Protection features (Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Equivalence Criteria:

• Package type (SOT-89-5/6)
• Surface mount configuration
• Moisture sensitivity level (MSL 1)

The substitute part NJM78LR05DU-TE1# maintains identical electrical and mechanical specifications while differing in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The NJM78LR05DU-TE1# is the direct substitute for the obsolete NJM78LR05DU-TE1. Both parts are manufactured by Nisshinbo Micro Devices Inc. and share identical electrical and mechanical specifications.

Key Differentiators:

Product Status: The substitute part (NJM78LR05DU-TE1#) carries an Active product status, ensuring ongoing availability and manufacturing support. The main part is classified as Obsolete, limiting future procurement options.

Compliance: The substitute part is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. The main part is RoHS non-compliant, which may present compliance challenges in applications subject to RoHS directives.

Packaging: The substitute is supplied in Tape & Reel (TR) format, standard for automated assembly operations. The main part is supplied in bulk packaging.

Inventory: Both parts are available in stock. The substitute maintains 845 pieces of new original inventory.

For new designs or component replenishment, the NJM78LR05DU-TE1# is the appropriate selection due to active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can NJM78LR05DU-TE1# be used as a direct replacement for NJM78LR05DU-TE1?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage (5V), output current (100mA), package type (SOT-89-5/6), and all electrical specifications including PSRR, quiescent current, and protection features.

Q: What is the difference between NJM78LR05DU-TE1 and NJM78LR05DU-TE1#?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance status (non-compliant vs. compliant), and packaging format (bulk vs. Tape & Reel). Electrical and mechanical specifications are identical.

Q: Why is the main part listed as Obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production of this specific part number. The substitute part NJM78LR05DU-TE1# remains in active production.

Q: Is the SOT-89-5/6 package compatible with existing PCB designs?

A: Yes. Both the main part and substitute use the SOT-89-5/6 surface mount package, ensuring pin-for-pin compatibility and identical PCB footprints.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The NJM78LR05DU-TE1# is RoHS Compliant, meeting the Restriction of Hazardous Substances directive requirements.

Q: Are there any differences in electrical performance between the two parts?

A: No. Both parts deliver identical electrical performance: 5V fixed output, 100mA maximum output current, 3.4mA quiescent current, 79dB PSRR at 120Hz, and identical protection and control features.

Q: What is the MSL rating for these parts?

A: Both parts have an MSL rating of 1 (Unlimited), indicating unlimited shelf life under normal storage conditions.
