Key Parameters

Substitute Part Grouping Explanation

Substitution of the 41640 is based on the following critical parameters:

Frequency Coverage: The substitute part must operate within or encompass the 7 GHz to 11 GHz operating band of the original component.

Isolation Performance: The substitute must meet or exceed the 16 dB minimum isolation specification to maintain signal separation characteristics.

VSWR Performance: The substitute must achieve comparable or superior VSWR performance to ensure impedance matching in the application circuit.

Physical Form Factor: The substitute must be available as a module package to maintain mechanical compatibility with existing mounting and integration requirements.

Regulatory Compliance: The substitute must maintain equivalent REACH and ECCN classifications to ensure regulatory continuity.

The PWD-5526-02-SMA-79 from Cinch Connectivity Solutions Midwest Microwave satisfies these substitution criteria through extended frequency coverage (6 GHz to 18 GHz), superior isolation performance (18 dB minimum), and module packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The PWD-5526-02-SMA-79 is the designated manufacturer-recommended substitute for the 41640. This component maintains active product status, ensuring ongoing availability and supply chain continuity. Both parts share identical REACH and ECCN classifications, eliminating regulatory transition requirements.

The substitute part demonstrates performance improvements across measured parameters: insertion loss is reduced from 0.7 dB to 0.5 dB, and isolation performance is enhanced from 16 dB to 18 dB minimum. The extended frequency range (6 GHz to 18 GHz) provides operational coverage beyond the original 7 GHz to 11 GHz specification, supporting broader application flexibility.

Both components maintain MSL 1 (Unlimited) moisture sensitivity classification and module packaging configuration, preserving mechanical and environmental handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the PWD-5526-02-SMA-79 directly replace the 41640 in existing applications?

A: The PWD-5526-02-SMA-79 is the manufacturer-recommended substitute and meets or exceeds all critical performance parameters within the 7 GHz to 11 GHz operating band. Physical dimensions differ slightly, requiring verification of mechanical mounting compatibility in the specific application.

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

A: The substitute provides lower insertion loss (0.5 dB versus 0.7 dB) and higher isolation (18 dB versus 16 dB minimum). The extended frequency range (6 GHz to 18 GHz) offers additional operational bandwidth beyond the original specification.

Q: Are there any compliance or regulatory differences?

A: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), eliminating regulatory transition requirements. The substitute maintains MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the significance of the 41640 being obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by TTM Technologies. The PWD-5526-02-SMA-79 is an active product with ongoing manufacturer support and supply availability.

Q: Are physical dimensions compatible between these parts?

A: The 41640 measures 1.200" L × 1.000" W × 0.370" H, while the PWD-5526-02-SMA-79 measures 1.000" L × 1.000" W. Mechanical mounting compatibility must be verified for the specific application before implementation.
