Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACA-107-T is determined by the following critical parameters:

• Antenna Type: Must be Chip configuration
• Termination Method: Must be Solder
• Mounting Type: Must be Surface Mount
• Physical Height: Must not exceed 0.047" (1.20mm) to maintain PCB layout compatibility
• Frequency Coverage: Substitute frequency range must encompass or overlap the 5.2GHz center frequency and support the 3.2GHz ~ 7.2GHz operational band
• Compliance Standards: Must maintain ROHS3 compliance and MSL 1 rating for manufacturing process compatibility

The substitute part 3100AT51A7200001E from Johanson Technology Inc. satisfies all structural and compliance requirements, with extended frequency range coverage suitable for multi-band applications.

Parameter Comparison

Engineering Selection Recommendations

The 3100AT51A7200001E is a direct structural substitute for the obsolete ACA-107-T. Both components share identical physical dimensions, solder termination, surface mount configuration, and compliance certifications (ROHS3, MSL 1). The substitute part maintains active product status with established supply chain availability.

The frequency range of the 3100AT51A7200001E (3.1GHz ~ 10.3GHz) fully encompasses the ACA-107-T operational band (3.2GHz ~ 7.2GHz), ensuring coverage at the 5.2GHz center frequency. The substitute exhibits different gain and return loss characteristics; design validation is required to confirm performance adequacy for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 3100AT51A7200001E directly replace the ACA-107-T in existing designs?

A: Physical and mechanical compatibility is confirmed. Both components feature identical 0.047" (1.20mm) height, solder termination, and surface mount configuration. Electrical performance differences (gain and return loss) require circuit-level evaluation to confirm functional equivalence for your specific application.

Q: What are the key differences between these two chip antennas?

A: The primary differences are center frequency (5.2GHz vs. 6.7GHz), gain (4.16dBi vs. 1.5dBi), and return loss specification (-9.5dB for the substitute). The substitute provides broader frequency coverage (3.1GHz ~ 10.3GHz vs. 3.2GHz ~ 7.2GHz).

Q: Are both parts compliant with current manufacturing standards?

A: Yes. Both the ACA-107-T and 3100AT51A7200001E are ROHS3 compliant with MSL 1 rating, suitable for standard surface mount assembly processes.

Q: What packaging format is available for the substitute part?

A: The 3100AT51A7200001E is supplied in Tape & Reel (TR) format, standard for high-volume surface mount production.

Q: Why is the ACA-107-T listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Abracon LLC. The 3100AT51A7200001E from Johanson Technology Inc. remains in active production with established supply availability.
