Substitute Part Grouping Explanation

Substitution of the DF1506M is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

Diode Type: Single Phase bridge rectifier
Voltage - Peak Reverse (Max): 600 V minimum
Current - Average Rectified (Io): 1.5 A minimum
Mounting Type: Through Hole
Package compatibility: 4-EDIP form factor

Secondary Considerations:

Operating temperature range: -65°C to 150°C preferred
Forward voltage (Vf): 1.1 V @ rated current
Reverse leakage current: 10 µA @ 600 V
RoHS3 compliance and REACH status

Substitute parts are grouped based on voltage rating and current capacity. Parts meeting or exceeding the 600 V / 1.5 A specification are direct electrical equivalents. Parts with lower current ratings (1 A) require application-level verification but maintain voltage compatibility. Parts with higher voltage ratings (800 V, 1 kV) are backward compatible for 600 V applications.

Engineering Selection Recommendations

Primary Recommendation: DB105-BP

DB105-BP from Micro Commercial Co is the most direct active substitute for DF1506M. It maintains 600 V peak reverse voltage rating and through-hole 4-EDIP mounting. Current rating is 1 A versus the original 1.5 A; applications operating at or below 1 A are fully compatible. DB105-BP is Active status with ROHS3 compliance and REACH Unaffected designation. Package dimensions differ slightly (0.321" versus 0.300"), requiring PCB layout verification for board-level compatibility.

Secondary Recommendation: DF206-G

DF206-G from Comchip Technology provides 600 V / 2 A rating, exceeding DF1506M specifications in current capacity. This part is Active status with ROHS3 compliance. The 2 A rating provides design margin for applications requiring higher current headroom. Package footprint is 4-EDIP (0.321"), consistent with DB105-BP.

Higher Voltage Alternative: DB106-BP

DB106-BP rated at 800 V / 1 A is suitable for applications where voltage margin is required. This part is Active status with full compliance certifications. Current rating of 1 A limits use to lower-power applications.

Obsolete Alternative: DF06M

DF06M from onsemi matches the 600 V / 1.5 A specification and maintains the 0.300" package dimension of the original DF1506M. However, DF06M is classified as Obsolete, offering no advantage over active alternatives for new procurement.

Frequently Asked Questions (FAQ)

Q: Can DB105-BP directly replace DF1506M in all applications?

DB105-BP is electrically compatible at 600 V rating. The current rating difference (1 A versus 1.5 A) requires application verification. If circuit current demand does not exceed 1 A, DB105-BP is a direct substitute. PCB layout must accommodate the 0.321" package dimension versus the original 0.300".

Q: What is the difference between the 4-EDIP (0.300") and 4-EDIP (0.321") packages?

Both are 4-EDIP form factors with identical pin configuration and electrical function. The dimension difference (0.300" versus 0.321") refers to the body width. PCB footprints must be verified for compatibility; 0.321" packages require slightly wider pad spacing.

Q: Is DF206-G suitable for DF1506M replacement?

Yes. DF206-G provides 600 V / 2 A rating, exceeding DF1506M specifications. The higher current capacity (2 A) ensures compatibility with applications rated up to 1.5 A. Package is 4-EDIP (0.321"), requiring PCB layout confirmation.

Q: Why is DF005M listed as a substitute if it is only 50 V rated?

DF005M is not a functional substitute for 600 V applications. It is included in the provided substitute list but is electrically incompatible due to voltage rating mismatch. DF005M is suitable only for 50 V applications.

Q: What compliance certifications should I verify for substitute parts?

All recommended active substitutes (DB105-BP, DF206-G, DB106-BP) carry ROHS3 compliance and REACH Unaffected status, matching the original DF1506M certifications. Verify ECCN and HTSUS codes (both EAR99 and 8541.10.0080) for export and tariff compliance in your supply chain.

Q: Can I use DB106-BP (800 V) in place of DF1506M (600 V)?

Yes, for electrical compatibility. The 800 V rating provides voltage margin for 600 V applications. Current rating is 1 A, limiting use to applications not exceeding 1 A. Package is 4-EDIP (0.321"), requiring PCB verification.
