Key Parameters

Substitute Part Grouping Explanation

The Abracon LLC APAMS-102 qualifies as a functional equivalent based on the following substitution criteria:

Matching Parameters:

• Antenna type: Flat bar configuration
• Frequency band coverage: 900MHz, 1.8GHz, 1.9GHz, 2.1GHz center frequencies
• Mounting method: Adhesive
• Cable length: 3m
• Form factor: Comparable physical dimensions (6.00mm vs 6.35mm height)
• Frequency group: Wide band multi-band operation

Operational Compatibility: The APAMS-102 covers the required frequency ranges (820MHz–960MHz, 1.71GHz–1.88GHz, 1.85GHz–1.99GHz, 1.9GHz–2.17GHz) which encompass the center frequencies of the original part. The antenna supports CDMA, GPRS, GSM, and UMTS applications, providing broader application coverage than the original specification.

Parameter Comparison

Engineering Selection Recommendations

The APAMS-102 is the designated manufacturer-recommended substitute for the obsolete 76000844. Selection of this alternative is supported by:

Product Status: The APAMS-102 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance & Certifications: The APAMS-102 is RoHS3 compliant and REACH affected, meeting current regulatory requirements for electronic components in most markets. The original 76000844 carries REACH unaffected status, indicating it predates current regulatory frameworks.

Frequency Coverage: The APAMS-102 frequency ranges fully encompass the center frequencies specified for the original part, with extended range capability supporting broader application flexibility.

Physical Compatibility: The substitute maintains comparable form factor with adhesive mounting and 3m cable configuration, supporting direct mechanical integration into existing designs with minimal layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the APAMS-102 directly replace the 76000844 in existing designs?

A: Yes. Both antennas share identical mounting type (adhesive), cable length (3m), frequency band centers (900MHz, 1.8GHz, 1.9GHz, 2.1GHz), and flat bar form factor. The APAMS-102 height of 6.00mm is slightly lower than the original 6.35mm, providing improved space efficiency.

Q: What is the significance of the gain difference (1.5dBi vs. 1–3dBi)?

A: The APAMS-102 is available in multiple gain configurations. Selection of the 1.5dBi or 2dBi variant will match or exceed the performance of the original part. Gain selection depends on specific application requirements and link budget calculations.

Q: Does the SMA Male termination on the APAMS-102 affect compatibility?

A: The termination type must match the connector interface in your system. If the original 76000844 used a different connector type, adapter cables or connector modification may be required. Verify the original termination specification before implementation.

Q: Why is the APAMS-102 listed as REACH affected while the original is REACH unaffected?

A: The original 76000844 predates REACH regulatory requirements. The APAMS-102, as an active production component, is subject to current REACH compliance obligations. Both parts meet applicable regulatory standards for their respective market periods.

Q: Is the APAMS-102 suitable for CDMA, GPRS, GSM, and UMTS applications?

A: Yes. The APAMS-102 explicitly supports these cellular standards through its multi-band frequency coverage and is designed for these application categories.
