Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents):

The HS5A (Tape & Reel variant) is the primary recommended replacement for the discontinued HS5A M6G. This part maintains identical electrical specifications and package configuration while offering active product status. The HS5A is available in higher inventory (931 pcs) compared to the original part.

For applications requiring alternative packaging formats, HS5A R7G (Cut Tape) and HS5A V7G are parametrically equivalent alternatives, though both are discontinued at DiGi Electronics. These variants are suitable only when existing inventory is available and long-term procurement is not required.

Alternative Selection (Similar Parts):

CGRC501-G (Comchip Technology) maintains the 50 V, 5 A specification with active product status and high inventory availability (5344 pcs). This part differs in recovery speed (Standard Recovery >500ns versus Fast Recovery ≤500ns) and forward voltage (1.15 V versus 1 V at 5 A). Selection of CGRC501-G is appropriate for applications where switching speed is not performance-critical and the higher forward voltage drop is acceptable.

For applications where current requirements can be reduced to 3 A, multiple active alternatives are available:

CURC301-G (Comchip Technology) — Fast Recovery characteristics matching the original part, 1 A inventory (1033 pcs)
ES3A-13-F (Diodes Incorporated) — Fast Recovery with superior reverse recovery time (25 ns), highest inventory availability (10300 pcs)
RS3A-13-F (Diodes Incorporated) — Fast Recovery characteristics, active status, 5545 pcs available
RS3A-E3/57T and RS3A-E3/9AT (Vishay General Semiconductor) — Fast Recovery, active status, lower inventory levels

Package Consideration:

ES3AB-13-F differs in package format (DO-214AA SMB versus DO-214AB SMC). This part is suitable only for applications where SMB package footprint is compatible with the circuit board design.

All recommended parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and equivalent thermal operating ranges (-55°C to 150°C or -65°C to 150°C).

Frequently Asked Questions (FAQ)

Q: Can HS5A M6G be directly replaced with HS5A?

A: Yes. The HS5A (Tape & Reel variant) is a parametric equivalent with identical electrical specifications (50 V, 5 A, 1 V forward voltage, 50 ns reverse recovery time) and DO-214AB (SMC) package. The primary difference is packaging format (Tape & Reel versus the original format) and active product status.

Q: What is the difference between HS5A M6G and CGRC501-G?

A: Both parts are rated for 50 V and 5 A in DO-214AB (SMC) packages. CGRC501-G differs in two parameters: recovery speed (Standard Recovery >500ns versus Fast Recovery ≤500ns) and forward voltage (1.15 V versus 1 V at 5 A). CGRC501-G is suitable for applications where switching speed is not critical and the additional forward voltage drop is acceptable.

Q: Can I use a 3 A rated diode instead of the 5 A HS5A M6G?

A: Substitution with 3 A rated parts (CURC301-G, ES3A-13-F, RS3A-13-F, RS3A-E3/57T, RS3A-E3/9AT) is possible only if the circuit design operates at or below 3 A average rectified current. The 50 V reverse voltage rating and DO-214AB (SMC) package remain compatible. This substitution requires circuit analysis to confirm current requirements do not exceed 3 A under all operating conditions.

Q: What is the significance of reverse recovery time (trr)?

A: Reverse recovery time affects switching speed and switching losses in high-frequency applications. The HS5A M6G has 50 ns trr (Fast Recovery). Alternatives with longer trr values (such as RS3A-13-F at 150 ns) are suitable for lower-frequency applications but may increase switching losses in high-frequency circuits. ES3A-13-F offers superior performance with 25 ns trr.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parametric equivalent and similar parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original HS5A M6G specifications.

Q: What is the difference between DO-214AB (SMC) and DO-214AA (SMB) packages?

A: DO-214AB (SMC) and DO-214AA (SMB) are different surface mount package formats with different footprints and land patterns. ES3AB-13-F uses the SMB package and is compatible only with circuit boards designed for SMB footprint. Verify package compatibility with your PCB design before selection.

Q: Which substitute part has the best availability?

A: ES3A-13-F (Diodes Incorporated) offers the highest inventory availability at 10300 pcs. This part is rated for 50 V, 3 A with Fast Recovery characteristics (25 ns trr) and is suitable for applications operating at 3 A or below.

Q: Can I use HS5A R7G or HS5A V7G as replacements?

A: HS5A R7G and HS5A V7G are parametric equivalents with identical electrical specifications to HS5A M6G. However, both are discontinued at DiGi Electronics. These parts are suitable only when existing inventory is available and long-term procurement is not required. For new designs, the active HS5A (Tape & Reel) variant is recommended.
