Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-282C-BLKG is determined by the following criteria:

Primary Compatibility Requirements:

• Diode configuration: 1 Pair Series Connection (mandatory)
• Package type: SC-70 / SOT-323 (mandatory for mechanical and thermal compatibility)
• Voltage rating: Must equal or exceed 15V peak reverse voltage
• Current rating: Must support application requirements within specified limits
• Capacitance and resistance characteristics: Must remain within acceptable ranges for RF applications

Substitute Parts Identified:

1. MA4E1338B1-1146T (MACOM Technology Solutions) - Active status, reduced voltage rating (8V), limited current (30mA)
2. 1PS70SB84,115 (Nexperia USA Inc.) - Active status, matching voltage rating (15V), automotive qualified
3. BAT54SWFILM (STMicroelectronics) - Active status, elevated voltage rating (40V), higher current capacity (300mA)

Parameter Comparison

Engineering Selection Recommendations

1PS70SB84,115 (Nexperia USA Inc.) is the primary substitute for direct replacement applications. This part maintains the 15V peak reverse voltage specification of the original HSMS-282C-BLKG, operates within the same SOT-323 package, and is actively manufactured. The part carries AEC-Q100 automotive qualification and ROHS3 compliance, supporting modern supply chain requirements. Operating temperature maximum of 125°C is lower than the original specification but remains suitable for most RF applications.

BAT54SWFILM (STMicroelectronics) is suitable for applications requiring higher voltage margin or increased current capacity. The 40V peak reverse voltage and 300mA current rating provide design headroom beyond the original specification. This part maintains the 150°C maximum operating temperature of the original device and is actively produced with ROHS3 compliance.

MA4E1338B1-1146T (MACOM Technology Solutions) is applicable only in current-limited applications where the 30mA maximum current is sufficient. The 8V peak reverse voltage rating is below the original 15V specification and restricts this part to lower-voltage circuit implementations. This substitute is not recommended for direct replacement in designs requiring the full 15V rating.

Frequently Asked Questions (FAQ)

Q: Can MA4E1338B1-1146T replace HSMS-282C-BLKG in all applications?

A: No. The MA4E1338B1-1146T has a maximum peak reverse voltage of 8V, which is below the 15V rating of the HSMS-282C-BLKG. This part is suitable only for circuits designed to operate at 8V or lower. Current capacity is also limited to 30mA compared to the original 1A specification.

Q: What is the primary advantage of 1PS70SB84,115 as a substitute?

A: The 1PS70SB84,115 maintains electrical parity with the original part at 15V peak reverse voltage and 30mA current rating, operates in the same SOT-323 package, and is actively manufactured with automotive qualification (AEC-Q100) and ROHS3 compliance. It is the most direct functional equivalent.

Q: Is BAT54SWFILM suitable for designs originally specified for HSMS-282C-BLKG?

A: Yes. The BAT54SWFILM exceeds the original specifications with 40V peak reverse voltage and 300mA current capacity, both higher than the 15V and 1A ratings of the HSMS-282C-BLKG. The SOT-323 package and 150°C maximum operating temperature match the original device. This part is suitable for direct substitution with additional design margin.

Q: Are all substitute parts available in the same packaging?

A: Yes. All three substitute parts are supplied in SC-70 / SOT-323 surface mount packaging, identical to the original HSMS-282C-BLKG. Mechanical compatibility is maintained across all alternatives.

Q: What compliance certifications should I verify for my application?

A: The 1PS70SB84,115 and BAT54SWFILM both carry ROHS3 compliance and REACH Unaffected status. If automotive qualification is required, the 1PS70SB84,115 includes AEC-Q100 certification. Verify compliance requirements against your specific application standards before final selection.
