NJM2930F05 Equivalent & Substitute Parts

Part Overview

The NJM2930F05 is a linear voltage regulator IC manufactured by Nisshinbo Micro Devices Inc., designed to deliver a fixed positive 5V output at 150mA in a TO-220-3 package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Linear regulators of this specification are used in applications requiring stable 5V power distribution with moderate current demands and thermal management through through-hole mounting. The obsolete status necessitates evaluation of substitute components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NJM2930F05 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Fixed output voltage of 5V
• Output current capability equal to or greater than 150mA
• Input voltage rating of 25V or higher
• Through-hole TO-220 package configuration
• Positive output configuration

Regulatory & Compliance Requirements:

• RoHS compliance status
• REACH compliance status
• Moisture sensitivity level (MSL 1 or equivalent)

The BA05T from Rohm Semiconductor meets these substitution criteria. While the BA05T provides higher output current (1A versus 150mA) and lower quiescent current (2.5mA versus 7mA), these represent performance enhancements rather than incompatibilities. The device maintains the same fixed 5V output, TO-220-3 package, and regulatory compliance profile.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement:

The BA05T is electrically and mechanically compatible with the NJM2930F05 in through-hole PCB applications. Both devices are housed in TO-220-3 packages and deliver fixed 5V outputs. The BA05T's higher current rating (1A) and lower quiescent current (2.5mA) provide operational margin without introducing incompatibility.

Compliance Considerations:

Both the NJM2930F05 and BA05T maintain RoHS and REACH compliance. The BA05T carries ROHS3 certification, representing current regulatory alignment. Both devices have MSL 1 moisture sensitivity ratings, indicating unlimited shelf life under standard storage conditions.

Thermal and Input Voltage Considerations:

The NJM2930F05 is rated for 26V maximum input, while the BA05T is rated for 25V maximum input. In applications operating near the upper input voltage limit, the NJM2930F05 specification provides 1V additional margin. The BA05T's wider operating temperature range (-40°C to 85°C versus -30°C to 75°C) accommodates extended environmental conditions.

Protection Feature Differences:

The BA05T includes over-voltage protection in addition to over-temperature and short-circuit protection. This additional protection may benefit applications subject to transient voltage events, though it does not affect pin-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BA05T directly replace the NJM2930F05 on existing PCBs?

A: Yes. Both devices use identical TO-220-3 through-hole package configurations with the same pin assignments for a 5V linear regulator. No PCB modifications are required.

Q: What is the difference in output current capability?

A: The NJM2930F05 is rated for 150mA output, while the BA05T is rated for 1A (1000mA). The BA05T can supply higher current loads. In applications requiring only 150mA, the BA05T operates well within its design envelope.

Q: Are there differences in quiescent current consumption?

A: Yes. The NJM2930F05 draws 7mA quiescent current, while the BA05T draws 2.5mA. The BA05T consumes less standby power, which may be advantageous in battery-powered or low-power applications.

Q: How do the PSRR specifications compare?

A: The NJM2930F05 provides 60dB PSRR at 120Hz, while the BA05T provides 55dB. The NJM2930F05 offers superior power supply rejection ratio by 5dB. In noise-sensitive analog applications, this difference may be relevant.

Q: What is the significance of the product status difference?

A: Both devices carry legacy status. The NJM2930F05 is marked obsolete, indicating end-of-life status. The BA05T is marked "Not For New Designs," indicating it remains available but is not recommended for new development. Both are suitable for sustaining existing products.

Q: Are there input voltage rating differences I should consider?

A: The NJM2930F05 is rated for 26V maximum input, while the BA05T is rated for 25V. Applications operating at input voltages between 25V and 26V should use the NJM2930F05 or verify that the BA05T's 25V rating is sufficient for the specific design.

Q: Do both devices have the same protection features?

A: No. The NJM2930F05 includes over-temperature and short-circuit protection. The BA05T includes over-current, over-temperature, and over-voltage protection. The additional over-voltage protection in the BA05T does not affect compatibility but provides enhanced transient protection.

Q: What is the operating temperature range difference?

A: The NJM2930F05 operates from -30°C to 75°C, while the BA05T operates from -40°C to 85°C. The BA05T supports a wider temperature range, beneficial for applications in extreme environments.
