SR4C005 Equivalent & Substitute Parts Reference

Part Overview

The SR4C005 is an RF antenna manufactured by Antenova, designed as a PCB trace antenna for multi-band cellular applications. This component operates across four frequency bands: 892MHz, 1.9GHz, 2.4GHz, and 2.6GHz, supporting GSM, LTE, and WCDMA standards. The part is currently in active production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified frequency ranges and mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR4C005 is determined by the following electrical and mechanical parameters:

Frequency Coverage: The substitute part must support the four center frequencies (892MHz, 1.9GHz, 2.4GHz, 2.6GHz) and maintain coverage across the specified frequency ranges (824MHz ~ 960MHz, 1.71GHz ~ 2.17GHz, 2.3GHz ~ 2.4GHz, 2.5GHz ~ 2.69GHz).

Antenna Type and Mounting: Surface mount termination with solder connection is required. Physical height constraints must not exceed the maximum specified dimension.

Electrical Performance: Gain, VSWR, and return loss values must be compatible with the application requirements for GSM, LTE, and WCDMA standards.

Compliance and Status: Active product status and RoHS compliance are baseline requirements for substitution consideration.

The PA.711.A from Taoglas Limited meets these substitution criteria through equivalent frequency band coverage, surface mount configuration, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the SR4C005 and PA.711.A maintain active product status with current RoHS compliance certifications. The SR4C005 is RoHS Compliant, while the PA.711.A is ROHS3 Compliant, indicating both meet current environmental and hazardous substance restrictions.

The PA.711.A provides extended frequency coverage beyond the SR4C005 specification, supporting additional center frequencies at 700MHz, 850MHz, and 2.1GHz. The frequency ranges specified for both parts overlap across the critical bands: 824MHz ~ 960MHz, 1.71GHz ~ 2.17GHz, 2.3GHz ~ 2.4GHz, and 2.5GHz ~ 2.69GHz.

Key differences in physical form factor exist: the SR4C005 is a PCB trace antenna with 1.60mm maximum height, while the PA.711.A is a chip antenna with 5.00mm maximum height. This dimensional difference may impact PCB layout and available mounting space.

Electrical performance characteristics differ: the SR4C005 provides 3.2dBi gain with 3.9 VSWR, while the PA.711.A offers variable gain (1.0dBi to 4.1dBi) with improved VSWR of 3. The PA.711.A also specifies maximum power handling at 5W.

Moisture sensitivity differs: the SR4C005 carries MSL 1 (unlimited), while the PA.711.A carries MSL 3 (168 hours), affecting storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can PA.711.A directly replace SR4C005 in all applications?

A: Both parts support the required frequency bands (892MHz, 1.9GHz, 2.4GHz, 2.6GHz) and GSM, LTE, WCDMA standards. However, physical form factor differences must be evaluated: SR4C005 is a PCB trace antenna (1.60mm height), while PA.711.A is a chip antenna (5.00mm height). PCB layout compatibility must be confirmed before substitution.

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

A: The SR4C005 provides fixed 3.2dBi gain with 3.9 VSWR and -6dB return loss. The PA.711.A offers variable gain (1.0dBi to 4.1dBi depending on band) with superior VSWR of 3. Both parts support the specified frequency ranges with adequate performance for cellular applications.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. The SR4C005 is RoHS Compliant, while PA.711.A is ROHS3 Compliant. Both maintain active product status. Moisture sensitivity differs: SR4C005 is MSL 1 (unlimited storage), while PA.711.A is MSL 3 (168-hour storage limit).

Q: What packaging options are available?

A: The SR4C005 packaging is not specified in the provided data. The PA.711.A is supplied in Tape & Reel (TR) packaging format.

Q: How do the frequency ranges compare?

A: Both parts cover the critical frequency ranges: 824MHz ~ 960MHz, 1.71GHz ~ 2.17GHz, 2.3GHz ~ 2.4GHz, and 2.5GHz ~ 2.69GHz. The PA.711.A extends coverage to 698MHz ~ 960MHz and 2.49GHz ~ 2.69GHz, providing additional bandwidth at the lower and upper frequency limits.

Q: What is the impact of different antenna types?

A: The SR4C005 PCB trace design integrates directly into the PCB layout with minimal height (1.60mm), suitable for space-constrained applications. The PA.711.A chip antenna requires discrete component placement with greater height (5.00mm), affecting board real estate and design flexibility.
