Substitute Part Grouping Explanation

Substitution of the SN75176BPSRG4 is determined by strict equivalence across the following critical parameters:

  • Protocol compatibility: RS422/RS485 half-duplex operation
  • Electrical specifications: 1/1 driver/receiver configuration, 50 mV receiver hysteresis, 4.75V–5.25V supply voltage range, 0°C–70°C operating temperature
  • Mechanical compatibility: 8-SOIC surface mount package with 0.209" (5.30mm) width
  • Regulatory compliance: ROHS3 compliance, REACH unaffected status, MSL Level 1

The SN75176BPSR meets all substitution criteria as an active equivalent part within the SN75176 product family. Both parts share identical electrical performance, package geometry, and regulatory certifications. The primary distinction is product status and packaging format availability.

Engineering Selection Recommendations

The SN75176BPSR is the direct equivalent substitute for the discontinued SN75176BPSRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical performance, package geometry, and regulatory compliance status. The SN75176BPSR is currently active in production and available through multiple packaging formats (Cut Tape and Digi-Reel), ensuring supply chain continuity for new designs and production replenishment.

Selection of the SN75176BPSR eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs. No design modifications, PCB layout changes, or firmware updates are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the SN75176BPSR be used as a direct replacement for the SN75176BPSRG4?

A: Yes. Both parts are electrically and mechanically identical. The SN75176BPSR is the active production equivalent and requires no design changes for substitution.

Q: Are there differences in package dimensions between these parts?

A: No. Both parts use the 8-SOIC package with identical dimensions (0.209" width, 5.30mm). PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the packaging formats offered?

A: The SN75176BPSRG4 was supplied in Digi-Reel format only. The SN75176BPSR is available in both Cut Tape (CT) and Digi-Reel formats, providing flexibility for different procurement and assembly requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Regulatory certifications are identical.

Q: Why is the SN75176BPSRG4 discontinued?

A: The SN75176BPSRG4 has been discontinued at DiGi Electronics. The SN75176BPSR remains the active production part within the SN75176 product family and is the recommended source for ongoing procurement.
