• Current - Average Rectified (Io): 100 mA
• Voltage - Forward (Vf) (Max) @ If: 450 mV @ 10 mA
• Current - Reverse Leakage @ Vr: 500 nA @ 10 V
• Technology: Schottky

Mechanical & Environmental Specifications:

• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 0603C/SOD-523F
• Mounting Type: Surface Mount
• Operating Temperature - Junction (Max): 125°C
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Only parts matching all of these parameters are classified as direct substitutes. No parameter relaxation or uprating is applied.

Parameter Comparison

Engineering Selection Recommendations

The CDBU0130R is a direct parametric equivalent to the CDBU0130R-HF. Both parts are manufactured by Comchip Technology and carry identical electrical, mechanical, and environmental specifications.

The CDBU0130R demonstrates significantly higher inventory availability (168,545 pcs versus 788 pcs), making it the preferred selection for applications requiring extended lead time assurance or volume procurement.

Selection between these parts is based on supply chain requirements and inventory availability rather than technical performance differentiation. No design modification, circuit re-evaluation, or performance testing is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can CDBU0130R replace CDBU0130R-HF in existing designs?

A: Yes. The CDBU0130R is a direct parametric equivalent with identical electrical specifications (30V reverse voltage, 100mA average rectified current, 450mV forward voltage @ 10mA), identical package (0603C/SOD-523F), and identical compliance ratings (ROHS3, MSL Level 1). No circuit modification is required.

Q: Are there any differences in performance between CDBU0130R-HF and CDBU0130R?

A: No. Both parts share identical specifications across all provided parameters: reverse voltage, forward voltage, reverse leakage current, operating temperature range, and package configuration.

Q: What is the significance of the "-HF" suffix in CDBU0130R-HF?

A: The "-HF" designation is a supplier or packaging variant identifier. The base product number CDBU0130 defines the core electrical and mechanical specifications. Both CDBU0130R-HF and CDBU0130R conform to the same base product specifications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical surface mount packaging (2-SMD, No Lead, 0603C/SOD-523F), identical mounting type (Surface Mount), and identical footprint requirements. No PCB layout modification is necessary.

Q: What compliance certifications apply to both parts?

A: Both CDBU0130R-HF and CDBU0130R are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99 and HTSUS 8541.10.0070.

Q: Which part should be selected for new designs?

A: Selection is based on supply availability. The CDBU0130R offers substantially higher inventory (168,545 pcs) compared to CDBU0130R-HF (788 pcs). For volume production or extended procurement windows, CDBU0130R is the recommended choice. For immediate availability of limited quantities, CDBU0130R-HF may be selected without performance impact.
