Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC5249-2.6BMM is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 2.6V fixed output
• Maximum output current: 300mA
• Input voltage rating: 6V maximum
• Dropout voltage: 0.6V @ 300mA
• Package type: 8-MSOP surface mount
• Control features: Enable and Reset functionality
• Protection mechanisms: Over-current, over-temperature, and UVLO protection
• Quiescent current: 200 µA
• PSRR performance: 65dB @ 120Hz

The MIC5249-2.6YMM qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction between these parts is packaging format (bulk versus tube) and product status (discontinued versus active).

Parameter Comparison

Engineering Selection Recommendations

The MIC5249-2.6YMM is the direct parametric equivalent for the discontinued MIC5249-2.6BMM. All electrical and mechanical specifications are identical, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The MIC5249-2.6YMM offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. This part also carries ROHS3 compliance, whereas the original MIC5249-2.6BMM is RoHS non-compliant. For new designs or production transitions, the MIC5249-2.6YMM is the appropriate selection.

Both parts are supplied in 8-MSOP surface-mount packages with identical pinout and thermal characteristics. No circuit modifications are required when transitioning from the MIC5249-2.6BMM to the MIC5249-2.6YMM.

Frequently Asked Questions (FAQ)

Q: Can the MIC5249-2.6YMM be used as a direct replacement for the MIC5249-2.6BMM?

A: Yes. The MIC5249-2.6YMM is electrically and mechanically identical to the MIC5249-2.6BMM. All output voltage, current, dropout, protection, and control specifications match exactly. The parts are pin-for-pin compatible with no circuit modifications required.

Q: What is the difference between the MIC5249-2.6BMM and MIC5249-2.6YMM?

A: The primary differences are packaging format (bulk versus tube) and product status. The MIC5249-2.6YMM is currently active and ROHS3 compliant, while the MIC5249-2.6BMM is discontinued and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-MSOP surface-mount package with 0.118" width (3.00mm). Pinout and thermal characteristics are identical.

Q: Why is the MIC5249-2.6BMM discontinued?

A: The MIC5249-2.6BMM is listed as discontinued at DiGi Electronics. The MIC5249-2.6YMM remains in active production and is the recommended source for ongoing supply.

Q: Does RoHS compliance affect circuit performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. The ROHS3-compliant MIC5249-2.6YMM delivers identical electrical performance to the non-compliant MIC5249-2.6BMM.
