Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA679S-GS08 is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode Type: PIN - Single (all substitutes must maintain this classification)
• Voltage - Peak Reverse (Max): Must equal or exceed 30V
• Current - Max: Must equal or exceed 50 mA
• Package / Case: 2-SMD configuration acceptable as functional equivalent
• RoHS Status: ROHS3 Compliant required
• Moisture Sensitivity Level: MSL 1 (Unlimited) required
• Product Status: Active required

Secondary Compatibility Parameters:

• Operating Temperature Range: Substitute must support minimum 125°C junction temperature
• Resistance @ If, F: Lower resistance values indicate improved RF performance
• Power Dissipation: Higher ratings provide design margin for thermal management

The substitute parts listed are MACOM Technology Solutions MA4P series RF PIN diodes. All substitutes meet or exceed the electrical specifications of the BA679S-GS08 while offering enhanced voltage ratings (100V to 600V) and power dissipation capabilities (6W to 11.5W). These parts are functionally equivalent for RF switching applications requiring higher voltage or power handling than the original specification.

Frequently Asked Questions (FAQ)

Q: Can MA4P series diodes directly replace the BA679S-GS08 in existing designs?

A: MA4P series diodes are functionally equivalent PIN diodes with enhanced electrical specifications. All substitutes meet or exceed the 30V voltage rating and 50 mA current requirement of the BA679S-GS08. Physical package compatibility must be confirmed for PCB layout, as the BA679S-GS08 uses SOD-80 MiniMELF while MA4P substitutes use 2-SMD packages.

Q: What is the primary difference between the BA679S-GS08 and MA4P substitutes?

A: The BA679S-GS08 is rated for 30V peak reverse voltage with 50 mA maximum current. MA4P substitutes offer higher voltage ratings (100V to 600V) and higher current ratings (100 mA), with power dissipation specifications ranging from 6W to 11.5W. These enhanced ratings provide design margin for applications with higher voltage or power requirements.

Q: Which substitute should be selected for a 200V application?

A: Three substitutes are rated for 200V: MA4P7002F-1072T (10W), MA4P7101F-1072T (11.5W), and MA4P7102F-1072T (11.5W). MA4P7101F-1072T and MA4P7102F-1072T offer superior RF performance with 500mOhm resistance at 100mA compared to 900mOhm for MA4P7002F-1072T. Selection depends on power dissipation requirements and packaging format preference.

Q: Are all substitutes available in the same packaging format as the BA679S-GS08?

A: No. The BA679S-GS08 uses Tape & Reel (TR) packaging in SOD-80 MiniMELF format. MA4P substitutes use 2-SMD packages with either Tape & Reel (TR) or Cut Tape & Digi-Reel® formats. PCB design and assembly equipment compatibility must be confirmed before substitution.

Q: Do all substitutes meet the same compliance standards as the BA679S-GS08?

A: Yes. All MA4P substitutes are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the BA679S-GS08. All parts are active products with current manufacturing status.

Q: What is the difference between MA4P7101F-1072T and MA4P7102F-1072T?

A: Both parts are rated for 200V with 11.5W power dissipation and 500mOhm resistance at 100mA. MA4P7101F-1072T uses ODS-1072 supplier device package format, while MA4P7102F-1072T does not specify a supplier device package designation. MA4P7102F-1072T has higher inventory availability (17300 units vs. 19180 units).

Q: Which substitute offers the best RF performance characteristics?

A: MA4P7101F-1072T, MA4P7102F-1072T, and MA4P7104F-1072T all feature 500mOhm resistance at 100mA, 100MHz, providing superior RF performance compared to other substitutes with 750mOhm or 900mOhm resistance values. Selection among these three depends on required voltage rating and packaging format.
