33-HC975-35 Equivalent & Substitute Parts Reference

Part Overview

The 33-HC975-35, manufactured by Calian, is a triple band antenna supporting Beidou, Galileo, GLONASS, GPS, and LTE. Mechanically, it utilizes a helical antenna type with an SMA Male connector mount and provides a gain of 35dB. The antenna operates in the UHF frequency group (1GHz ~ 2GHz), with center frequencies at 1.202GHz and 1.5655GHz, and specific frequency ranges of 1.164GHz ~ 1.24GHz and 1.525GHz ~ 1.606GHz. The ingress protection rating is IP67, the mounting type is connector mount, and its maximum height is 2.457” (62.40mm). The part status is Obsolete, necessitating the identification of direct alternatives to ensure design continuity, RoHS3 compliance, and inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Calian 33-HC975-35 is determined based on the following parameters: frequency group, frequency (center/band), frequency range, antenna type, number of bands, VSWR, gain, termination style, ingress protection rating, mounting type, height, application, RoHS compliance, MSL rating, ECCN, and product status. Acceptable substitutes must match these specified values to ensure electrical and mechanical compatibility within the product category. All listed substitute part numbers meet or align with these criteria as provided in the input.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute models for 33-HC975-35 is governed by product status, RoHS3 compliance, moisture sensitivity level (1 – Unlimited), and export controls as defined by ECCN 7A994 and HTSUS 8529.10.4040. Both 33-HC882-35 and 33-HC977-35 substitutes are listed as RoHS3 compliant, MSL 1 (Unlimited), and conform with the specified ECCN and HTSUS codes. As the original part is obsolete, only substitute parts with identical or tighter compliance and availability are considered.
