Substitute Part Grouping Explanation

Substitution of the obsolete CLLR1-01 BK is based on functional equivalence within the diode rectifier category. The CMR1-01M BK serves as a direct substitute, sharing the same manufacturer (Central Semiconductor Corp) and functional classification as a general-purpose rectifier diode. The substitution logic is grounded in the following criteria:

Key Substitution Parameters:

• Functional category: General-purpose rectifier diode
• Manufacturer alignment: Central Semiconductor Corp
• Active product status: Ensures ongoing availability and manufacturer support
• Electrical performance specifications: Voltage and current ratings suitable for standard rectification applications
• Package compatibility: Surface mount configuration for modern assembly processes

The CMR1-01M BK maintains electrical characteristics appropriate for applications previously served by the CLLR1-01 BK, with documented specifications and active inventory status.

Parameter Comparison

Engineering Selection Recommendations

The CMR1-01M BK is the appropriate substitute for the obsolete CLLR1-01 BK based on the following engineering criteria:

Product Status Alignment: The CMR1-01M BK maintains Active product status with current manufacturer support, ensuring long-term availability and technical documentation access. This contrasts with the CLLR1-01 BK's Obsolete classification, which restricts future procurement and support options.

Regulatory Compliance: The CMR1-01M BK carries EAR99 ECCN classification and REACH Unaffected status, confirming compliance with current export control and environmental regulations. These certifications support deployment in regulated applications and international markets.

Functional Equivalence: Both components serve the general-purpose rectifier diode function within the Central Semiconductor Corp product line. The CMR1-01M BK provides documented electrical specifications (100 V reverse voltage, 1 A average rectified current) suitable for standard rectification circuit requirements.

Manufacturing and Assembly Compatibility: The CMR1-01M BK employs surface mount technology (SMA package, DO-214AC case), aligning with contemporary PCB assembly processes and reducing integration complexity compared to legacy through-hole alternatives.

Frequently Asked Questions (FAQ)

Q: Can the CMR1-01M BK directly replace the CLLR1-01 BK in existing designs?

A: The CMR1-01M BK serves as a functional substitute for the obsolete CLLR1-01 BK within the general-purpose rectifier diode category. Compatibility depends on circuit voltage and current requirements matching the CMR1-01M BK specifications (100 V maximum reverse voltage, 1 A average rectified current). Physical package differences must be evaluated for PCB layout compatibility.

Q: What are the primary electrical differences between these components?

A: The CLLR1-01 BK specifications are not fully documented in available technical data. The CMR1-01M BK provides complete electrical characterization: 100 V DC reverse voltage rating, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, and 5 µA maximum reverse leakage current at 100 V. These parameters define the operating envelope for substitute applications.

Q: Why is the CMR1-01M BK classified as a substitute rather than an exact equivalent?

A: The CLLR1-01 BK's complete electrical specifications are not available in the provided technical documentation. Substitution is established through functional category alignment (general-purpose rectifier diode), manufacturer consistency (Central Semiconductor Corp), and active product status. Full electrical equivalence cannot be confirmed without complete CLLR1-01 BK specifications.

Q: What packaging considerations apply to this substitution?

A: The CMR1-01M BK uses surface mount technology (SMA package, DO-214AC case), which differs from legacy through-hole configurations. PCB design modifications may be required to accommodate the surface mount footprint. Assembly process compatibility with existing manufacturing equipment must be verified.

Q: Are there regulatory or compliance implications for this substitution?

A: The CMR1-01M BK carries EAR99 ECCN classification and REACH Unaffected status, confirming compliance with current export control and environmental regulations. These certifications support deployment in regulated applications. The obsolete CLLR1-01 BK does not carry current regulatory documentation.

Q: How does operating temperature range affect component selection?

A: The CMR1-01M BK operates across a junction temperature range of -65°C to 150°C, suitable for industrial and commercial applications. Operating temperature requirements for the original CLLR1-01 BK are not documented. Circuit thermal management and ambient operating conditions must be evaluated against the CMR1-01M BK's specified temperature range.
