Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Frequency band coverage (1.575GHz and/or 2.4GHz operation)
• Antenna type (Chip or Ceramic Patch)
• Termination method (Solder)
• Mounting configuration (Surface Mount)
• Physical form factor compatibility

Identified Substitute Groups:

Group 1: Dual-Band Chip Antennas (1.575GHz + 2.4GHz)

• SGGP.25.4.A.02 (Taoglas): Ceramic Patch, 1.575GHz/1.602GHz, Solder termination
• SDWA.01 (Taoglas): Chip, 2.4GHz/5.8GHz, Solder termination

Group 2: Navigation-Band Antennas (1.575GHz Primary)

• CGIP.25.4.A.02 (Taoglas): Ceramic Patch, 1.575GHz/1.621GHz GPS/Iridium, Pin termination
• SGGP.12.4.A.02 (Taoglas): Integrated Chip, 1.575GHz/1.602GHz GPS/GLONASS, Solder termination

Group 3: Cellular/Wideband Chip Antennas

• PA.25A (Taoglas): Chip, 850MHz/900MHz/1.7GHz-2.1GHz, Solder termination
• PCS.07.A (Taoglas): Chip, 850MHz/900MHz/1.8GHz-2.1GHz, Solder termination

Parameter Comparison

Engineering Selection Recommendations

For 1.575GHz/2.4GHz Dual-Band Applications: SGGP.25.4.A.02 provides direct frequency band coverage with solder termination and surface mount configuration. Height increase from 1.10mm to 4.00mm requires PCB layout verification. MSL rating downgrade from Level 1 to Level 3 necessitates controlled storage conditions (168-hour limit at 60% RH/30°C).

For 2.4GHz Primary with Extended Frequency Range: SDWA.01 covers 2.4GHz operation with additional 5.8GHz capability. Chip antenna type and minimal height (1.50mm) maintain form factor compatibility. MSL Level 3 rating applies equivalent storage requirements as other Taoglas substitutes.

For 1.575GHz Navigation-Band Applications: SGGP.12.4.A.02 and CGIP.25.4.A.02 both address 1.575GHz operation. SGGP.12.4.A.02 maintains solder termination and integrated chip configuration. CGIP.25.4.A.02 uses pin termination, requiring PCB footprint redesign.

For Cellular/Wideband Coverage: PA.25A and PCS.07.A extend frequency coverage to 850MHz-2.1GHz range. These parts are suitable only for applications requiring cellular band support beyond the W3043 specification.

All substitute parts maintain ROHS3 compliance and Active product status. Selection must account for MSL rating differences and physical height constraints relative to available PCB clearance.

Frequently Asked Questions (FAQ)

Q: Can SGGP.25.4.A.02 directly replace W3043 in all applications? A: SGGP.25.4.A.02 covers the 1.575GHz band but operates at 1.602GHz for the second band instead of 2.4GHz. Frequency band compatibility must be verified against application requirements. Physical height increases from 1.10mm to 4.00mm; PCB layout clearance must be confirmed. MSL rating changes from Level 1 to Level 3, requiring controlled storage at 60% RH/30°C with 168-hour maximum exposure.

Q: What is the impact of MSL rating differences? A: W3043 carries MSL Level 1 (unlimited moisture exposure), while most Taoglas substitutes are MSL Level 3 (168-hour limit at 60% RH/30°C). Level 3 components require sealed packaging and controlled handling during manufacturing. Exposure beyond 168 hours necessitates baking at 125°C for 24 hours before assembly.

Q: Why does CGIP.25.4.A.02 use pin termination instead of solder? A: CGIP.25.4.A.02 is designed for pin-based connection, requiring different PCB footprint and assembly process. This termination type is not interchangeable with W3043 solder termination without circuit board redesign.

Q: Can PA.25A or PCS.07.A substitute for W3043? A: PA.25A and PCS.07.A are cellular-band antennas (850MHz-2.1GHz) with no direct 1.575GHz coverage. These parts are suitable only for applications requiring cellular frequency bands not present in W3043 specification.

Q: What packaging considerations apply to substitutes? A: W3043 is supplied in Tape & Reel (TR) format. CGIP.25.4.A.02 uses Tray packaging, requiring different handling and pick-and-place equipment configuration. All other substitutes maintain TR packaging compatibility.

Q: How do antenna type differences affect performance? A: W3043 is a chip antenna; SGGP.25.4.A.02 and CGIP.25.4.A.02 are ceramic patch types. Ceramic patch antennas typically provide higher gain but require larger PCB footprint and clearance. Chip antennas offer compact form factor with lower profile height.
