Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM25115AMTX is determined by strict equivalence across the following critical parameters:

• Identical base product number (LM25115) ensuring functional and pin compatibility
• Matching package specification (16-TSSOP with 0.173" width, 4.40mm)
• Equivalent voltage input range (0V ~ 42V)
• Equivalent supply voltage range (4.5V ~ 30V)
• Identical supply current specification (4 mA)
• Matching operating temperature range (-40°C ~ 125°C)
• Surface mount mounting type consistency
• Secondary-side controller application compatibility

The LM25115AMTX/NOPB qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is product status and packaging format, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The LM25115AMTX/NOPB is the direct functional equivalent of the LM25115AMTX. Selection between these parts should be based on the following criteria:

Product Status: The LM25115AMTX is classified as Obsolete, while the LM25115AMTX/NOPB maintains Active status. For new designs or long-term production requirements, the Active status part ensures continued manufacturer support and availability.

Compliance Requirements: The LM25115AMTX/NOPB carries ROHS3 Compliant certification, whereas the original part is RoHS non-compliant. Applications subject to RoHS directives or customer compliance mandates require the LM25115AMTX/NOPB.

Packaging Format: The LM25115AMTX/NOPB is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original part is available in bulk packaging. Packaging selection depends on production volume and assembly methodology.

Regulatory Status: Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications, indicating equivalent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the LM25115AMTX/NOPB be used as a direct replacement for the LM25115AMTX?

A: Yes. Both parts share identical electrical specifications, package dimensions, pin configuration, and functional characteristics. The LM25115AMTX/NOPB is a direct substitute with no circuit modifications required.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates "No Plumbum" (lead-free) construction and is associated with the Tape & Reel packaging format. This suffix reflects the part's RoHS3 compliance status.

Q: Why is the original LM25115AMTX classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LM25115AMTX/NOPB represents the current active equivalent, ensuring access to ongoing supply and manufacturer technical support.

Q: Are there packaging considerations when switching from LM25115AMTX to LM25115AMTX/NOPB?

A: The LM25115AMTX/NOPB is supplied in Tape & Reel format optimized for automated pick-and-place assembly. If your production process requires bulk packaging, alternative sourcing or reeling services may be necessary. The physical package dimensions remain identical.

Q: Do both parts meet the same temperature and voltage specifications?

A: Yes. Both parts operate across the identical temperature range (-40°C to 125°C) and voltage specifications (input 0V to 42V, supply 4.5V to 30V). Thermal and electrical performance characteristics are equivalent.

Q: What compliance certifications differ between these parts?

A: The primary compliance difference is RoHS status. The LM25115AMTX/NOPB is ROHS3 Compliant, while the original is RoHS non-compliant. Both maintain identical REACH Unaffected and EAR99 ECCN classifications.
