Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA277,115 is determined by matching the following critical electrical and mechanical parameters:

• Diode Type: Standard - Single configuration
• Voltage - Peak Reverse (Max): 35V minimum rating
• Current - Max: 100 mA minimum rating
• Power Dissipation (Max): 715 mW minimum rating
• Package / Case: SOD-523 form factor
• Operating Temperature Range: -65°C to 150°C (TJ)
• RoHS Compliance: ROHS3 Compliant status

The BA891,115 meets all substitution criteria with identical ratings across these parameters. Capacitance and resistance characteristics differ slightly but remain within acceptable ranges for standard diode applications where these secondary parameters are not design-critical constraints.

Parameter Comparison

Engineering Selection Recommendations

The BA891,115 is the direct substitute for the BA277,115 based on matching electrical specifications and SOD-523 packaging. The BA891,115 holds active product status with higher inventory availability (6449 pcs vs. 759 pcs), ensuring long-term procurement reliability. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements. Selection of the BA891,115 eliminates obsolescence risk while preserving all critical electrical and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can BA891,115 directly replace BA277,115 in existing designs?

A: Yes. Both parts share identical peak reverse voltage (35V), maximum current (100 mA), power dissipation (715 mW), and SOD-523 packaging. Operating temperature ranges and RoHS compliance are equivalent.

Q: What are the differences between BA277,115 and BA891,115?

A: The primary differences are product status (obsolete vs. active) and packaging format (unspecified vs. Tape & Reel). Capacitance is measured at different bias points (1.2pF @ 6V vs. 0.9pF @ 3V), and BA891,115 includes specified resistance data (500mOhm @ 10mA, 100MHz). These variations do not affect substitution eligibility for standard diode applications.

Q: Why is BA277,115 obsolete?

A: BA277,115 is classified as obsolete by the manufacturer. BA891,115 serves as the active equivalent, ensuring continued availability and design support.

Q: Are there packaging considerations when substituting?

A: Both parts use SOD-523 packaging. BA891,115 is supplied in Tape & Reel format, which is standard for production environments. Verify reel specifications match your assembly process requirements.

Q: Do compliance certifications remain valid with substitution?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1). Regulatory and environmental certifications transfer directly between parts.
