CLL4713 BK TIN/LEAD Equivalent & Substitute Parts

Part Overview

The CLL4713 BK TIN/LEAD is a surface mount Zener diode rated at 30 V nominal voltage with 500 mW maximum power dissipation and ±5% tolerance. Manufactured by Central Semiconductor Corp, this component is packaged in DO-213AC (MINI-MELF, SOD-80) format and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts with active availability are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLL4713 BK TIN/LEAD is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Zener voltage: 30 V nominal
• Power rating: 500 mW maximum
• Voltage tolerance: ±5%
• Reverse leakage current: 10 nA @ 22.8 V
• Forward voltage: 1.5 V @ 100 mA

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount
• Package format compatibility

Product Status Consideration:

• Substitute parts must have active product status to ensure long-term availability

The CMHZ4713 BK TIN/LEAD meets all electrical equivalence criteria and maintains active product status. However, the package format differs from the original part, requiring mechanical evaluation during integration.

Parameter Comparison

Engineering Selection Recommendations

CMHZ4713 BK TIN/LEAD as Primary Substitute:

The CMHZ4713 BK TIN/LEAD is electrically equivalent to the CLL4713 BK TIN/LEAD across all critical parameters: 30 V nominal Zener voltage, 500 mW power rating, ±5% tolerance, and identical reverse leakage and forward voltage characteristics. The substitute part carries active product status, ensuring availability for production and future procurement.

Operating Temperature Consideration:

The CMHZ4713 BK TIN/LEAD operates within the range of -65°C to 150°C (TJ), compared to the original part's -65°C to 200°C (TJ). Applications requiring operation above 150°C junction temperature require thermal analysis to confirm the substitute part's suitability.

Package Format Difference:

The substitute part uses SOD-123 packaging instead of the original SOD-80 (DO-213AC, MINI-MELF) format. PCB layout and mechanical mounting modifications are necessary for integration. Both packages are surface mount formats with industry-standard footprints.

Compliance Status:

Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications. The substitute part carries REACH Unaffected status, confirming regulatory compliance for European markets.

Frequently Asked Questions (FAQ)

Q: Can the CMHZ4713 BK TIN/LEAD directly replace the CLL4713 BK TIN/LEAD in existing designs?

A: Electrical substitution is valid. The CMHZ4713 BK TIN/LEAD provides identical Zener voltage, power rating, tolerance, and leakage characteristics. However, the SOD-123 package differs from the original SOD-80 format, requiring PCB layout and footprint modifications.

Q: What is the impact of the operating temperature range difference?

A: The substitute part's maximum junction temperature is 150°C versus the original 200°C. For applications operating below 150°C junction temperature, this difference has no impact. Applications requiring higher junction temperatures must evaluate thermal performance independently.

Q: Are both parts RoHS compliant?

A: The CLL4713 BK TIN/LEAD is RoHS non-compliant. The CMHZ4713 BK TIN/LEAD compliance status is not specified in the provided data. Verify RoHS compliance requirements with the supplier before final selection.

Q: What are the physical differences between SOD-80 and SOD-123 packages?

A: SOD-80 (MINI-MELF) and SOD-123 are both surface mount packages with different footprint dimensions. SOD-123 is a smaller format. PCB design files and assembly specifications must be updated to accommodate the package change.

Q: Is the substitute part available in the same tin/lead finish?

A: Yes, the CMHZ4713 BK TIN/LEAD is specified with the same BK TIN/LEAD finish as the original part.

Q: What inventory status should be considered for production planning?

A: The CLL4713 BK TIN/LEAD has 1333 pieces in stock but is obsolete. The CMHZ4713 BK TIN/LEAD has 699 pieces in stock with active product status, ensuring continued availability for future orders.
