Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE42552MLIB-Z is determined by the following critical parameters:

Circuit topology must remain SPDT to maintain functional equivalence in switching applications. The 50 Ohm impedance is a fundamental requirement for RF matching and cannot be altered. Operating temperature range of -40°C to 85°C establishes the thermal envelope for system compatibility. Surface mount packaging in 16-QFN format ensures mechanical and electrical compatibility with existing PCB layouts.

The PE42553B-Z qualifies as a substitute based on matching circuit topology (SPDT), identical impedance (50 Ohm), compatible operating temperature range (-40°C to 85°C), and identical package format (16-QFN 3x3). The substitute part extends frequency capability to 8 GHz, improves isolation to 45 dB, and reduces insertion loss to 0.85 dB. Supply voltage range expansion from 3V-3.6V to 2.3V-5.5V provides additional design flexibility. The PE42553B-Z is classified as Active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The PE42553B-Z is the qualified substitute for the obsolete PE42552MLIB-Z. Both parts share identical SPDT circuit topology, 50 Ohm impedance, operating temperature range, and 16-QFN (3x3) package format, ensuring direct functional and mechanical compatibility.

The PE42553B-Z offers performance improvements including extended frequency range to 8 GHz, enhanced isolation at 45 dB versus 28 dB, and reduced insertion loss at 0.85 dB versus 1 dB. Supply voltage range expansion to 2.3V-5.5V accommodates broader system requirements. The substitute part maintains Active product status, ensuring long-term availability and manufacturing support.

Compliance certifications differ between the parts. The PE42553B-Z carries ROHS3 compliance and REACH Unaffected status, while the original part lists Vendor Undefined REACH status. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Moisture sensitivity increases from MSL 1 to MSL 3, requiring adherence to 168-hour storage and handling protocols for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the PE42553B-Z directly replace the PE42552MLIB-Z in existing designs?

A: Yes. Both parts maintain identical SPDT circuit topology, 50 Ohm impedance, operating temperature range (-40°C to 85°C), and 16-QFN (3x3) package format. PCB layout and electrical connections remain compatible without modification.

Q: What are the key performance differences between these parts?

A: The PE42553B-Z extends frequency capability from 7.5 GHz to 8 GHz, improves isolation from 28 dB to 45 dB, and reduces insertion loss from 1 dB to 0.85 dB. Supply voltage range expands from 3V-3.6V to 2.3V-5.5V. IIP3 performance is comparable at 65 dBm versus 66 dBm.

Q: Are there packaging considerations when switching to the PE42553B-Z?

A: Both parts use 16-QFN (3x3) surface mount packages. The PE42553B-Z uses 16-VFQFN variant versus 16-WFQFN for the original part. Footprint dimensions remain identical. Moisture sensitivity increases from MSL 1 (Unlimited) to MSL 3 (168 Hours), requiring compliance with extended storage and handling protocols.

Q: What is the supply voltage compatibility range for the substitute part?

A: The PE42553B-Z operates across 2.3V to 5.5V, compared to the original part's 3V to 3.6V range. This expanded range provides design flexibility for systems operating at lower or higher supply voltages while maintaining the original 3V-3.6V operating point.

Q: Are regulatory and compliance certifications equivalent?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The PE42553B-Z carries ROHS3 compliance and REACH Unaffected status. The original part lists Vendor Undefined REACH status. Verify compliance requirements for your specific application and region.

Q: Why is the original PE42552MLIB-Z classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The PE42553B-Z, classified as Active, represents the current production equivalent with enhanced performance characteristics and improved compliance certifications.
