HSMP-482B-BLKG RF PIN Diode Equivalent & Substitute Parts

Part Overview

The HSMP-482B-BLKG is an RF PIN diode manufactured by Broadcom Limited, designed for RF switching and attenuation applications. This single PIN diode operates at a peak reverse voltage of 50V with a maximum current rating of 1A in an SOT-323 package. The product is currently obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMP-482B-BLKG is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Diode Type: PIN - Single (required match)
• Voltage - Peak Reverse (Max): Must equal or exceed 50V
• Current - Max: Must equal or exceed 1A
• Package compatibility: Physical form factor must accommodate circuit board layout

Substitute Parts Identified:

1. CLA4605-085LF (Skyworks Solutions Inc.) - Meets minimum voltage and current requirements with enhanced specifications
2. CLA4608-085LF (Skyworks Solutions Inc.) - Exceeds voltage and current requirements with higher power dissipation capability

Both substitute parts are manufactured by Skyworks Solutions Inc., are in active production status, and meet or exceed the electrical parameters of the obsolete HSMP-482B-BLKG.

Engineering Selection Recommendations

CLA4605-085LF Selection:

• Recommended for direct substitution in applications requiring 50V to 60V operation
• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance meets current environmental regulations
• Higher current rating (1.5A vs 1A) provides design margin
• Lower capacitance at measurement frequency may improve high-frequency performance characteristics

CLA4608-085LF Selection:

• Recommended for applications requiring higher voltage headroom or operating in elevated voltage environments
• 180V peak reverse voltage rating provides significant design margin above the original 50V specification
• Active product status with higher inventory availability
• ROHS3 compliance meets current environmental regulations
• Higher power dissipation rating (2W) accommodates increased thermal requirements
• Lower resistance at measurement frequency may reduce insertion loss in RF switching applications

Both substitute parts are in active production with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory compliance and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can CLA4605-085LF or CLA4608-085LF directly replace HSMP-482B-BLKG in existing designs?

A: Both parts meet or exceed the electrical requirements (voltage, current, diode type). However, package differences must be evaluated. The HSMP-482B-BLKG uses SOT-323 packaging, while substitutes use 3-QFN (2x2) packaging. PCB layout modifications are required.

Q: What is the primary difference between CLA4605-085LF and CLA4608-085LF?

A: The primary difference is voltage rating. CLA4605-085LF is rated for 60V peak reverse voltage, while CLA4608-085LF is rated for 180V. CLA4608-085LF also provides higher power dissipation (2W vs 1W). Selection depends on circuit voltage requirements.

Q: Are both substitute parts available in production quantities?

A: Yes. CLA4605-085LF has 6534 pieces in stock, and CLA4608-085LF has 16543 pieces in stock as new original inventory.

Q: Do the substitute parts meet environmental compliance requirements?

A: Yes. Both CLA4605-085LF and CLA4608-085LF are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: How do the capacitance and resistance characteristics compare?

A: Capacitance values differ due to different measurement conditions. CLA4605-085LF shows 0.45pF at 6V, while HSMP-482B-BLKG shows 0.75pF at 20V. Resistance measurements are taken at different frequencies (100MHz vs 500MHz), making direct comparison dependent on application frequency requirements.
