Engineering Selection Recommendations
Preferred Substitutes (Active Product Status):
DF005M and DF2005-G are the recommended substitutes for new designs and ongoing procurement. DF005M maintains the original 50V rating with 1A current capacity and preserves the 0.300" (7.62mm) package footprint of the DF15005M, ensuring direct PCB compatibility. DF2005-G provides enhanced current capacity at 2A while maintaining 50V voltage rating, offering design margin for applications requiring higher current delivery.
DB105-BP and DB106-BP from Micro Commercial Co provide active product status with voltage ratings exceeding the original 50V specification. These parts accommodate higher voltage stress conditions while maintaining 1A current capacity and through-hole mounting compatibility.
Secondary Substitutes (Not For New Designs):
DB101-BP through DB104-BP are classified as Not For New Designs but remain available for legacy system support. These parts maintain electrical compatibility at their respective voltage ratings (50V to 400V) with 1A current capacity.
Obsolete Alternatives:
DF06M is classified as Obsolete and should not be selected for new applications despite matching the 1.5A current rating at 600V.
Compliance Considerations:
All recommended substitutes maintain ROHS3 compliance and EAR99 export classification consistent with the original DF15005M specification.
Frequently Asked Questions (FAQ)
Q: Can DB101-BP directly replace DF15005M in all applications?
A: DB101-BP provides electrical compatibility at the 50V voltage rating but with reduced current capacity (1A versus 1.5A). Substitution is valid only when circuit design accommodates the lower current rating. Package dimensions differ slightly (0.321" versus 0.300" pin spacing), requiring PCB layout verification.
Q: What is the primary difference between DF005M and DF2005-G?
A: DF005M maintains 1A current capacity at 50V with 0.300" package spacing, providing direct footprint compatibility with DF15005M. DF2005-G increases current capacity to 2A at 50V but uses 0.321" package spacing, requiring PCB layout adjustment. Both are Active products suitable for new designs.
Q: Why are DB105-BP and DB106-BP listed as substitutes if they have higher voltage ratings?
A: Higher voltage ratings provide design margin and are electrically compatible with 50V applications. These parts are suitable for circuits where voltage stress conditions may exceed the original 50V specification or where standardization on higher-voltage components is preferred. Both are Active products from Micro Commercial Co.
Q: Can DF06M be used as a substitute despite Obsolete status?
A: DF06M is not recommended for new designs due to Obsolete classification. While it matches the 1.5A current rating and provides 600V voltage capability, Active alternatives such as DF005M or DF2005-G should be prioritized for procurement and design continuity.
Q: What package compatibility considerations apply to substitute selection?
A: The original DF15005M uses 4-EDIP (0.300", 7.62mm) spacing. DF005M and DF06M maintain this spacing for direct PCB compatibility. DB101-BP through DB107-BP and DF2005-G use 4-EDIP (0.321", 8.15mm) spacing, requiring PCB layout verification before substitution. All parts maintain through-hole mounting type.
Q: Are all substitute parts RoHS3 compliant?
A: All listed substitute parts maintain ROHS3 compliance consistent with the original DF15005M specification, ensuring regulatory compatibility for applications subject to RoHS requirements.
