Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP.10D.01 is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency Alignment: Center frequency must be 1.575GHz to maintain GPS band compatibility
• Antenna Type: Ceramic patch construction required for form factor and performance consistency
• Mounting Configuration: Surface mount with solder termination to match PCB integration requirements
• Physical Dimensions: Maximum height of 0.157" (4.00mm) to ensure mechanical fit within enclosure constraints
• VSWR Specification: Maximum VSWR of 2 to maintain impedance matching performance
• Compliance Standards: ROHS3 compliance and MSL 3 rating required for manufacturing and storage compatibility

The AP.10H.01 meets all these substitution criteria while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The AP.10H.01 is the qualified substitute for the obsolete AP.10D.01. Both components share identical frequency, antenna type, VSWR, mounting configuration, physical dimensions, and compliance certifications. The AP.10H.01 maintains active product status with established supply chain availability (2414 pcs in stock versus 905 pcs for the obsolete part).

The primary performance difference is gain specification: AP.10H.01 operates at -10dBic compared to -3dBic for the AP.10D.01. The substitute additionally incorporates an integrated filter alongside the LNA, providing enhanced signal conditioning. These enhancements are compatible with GPS navigation applications and do not introduce mechanical or electrical incompatibilities.

Both parts satisfy ROHS3 compliance and MSL 3 moisture sensitivity requirements, ensuring equivalent handling and storage protocols during manufacturing and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can AP.10H.01 directly replace AP.10D.01 in existing designs?

A: Yes. Both antennas share identical frequency (1.575GHz), antenna type (ceramic patch), VSWR (2), mounting type (surface mount), termination method (solder), and physical dimensions (0.157" maximum height). PCB footprints and solder pad configurations are compatible.

Q: What is the significance of the gain difference between -3dBic and -10dBic?

A: Gain specification indicates antenna radiation efficiency. The AP.10H.01 operates at lower gain with integrated filter functionality, providing enhanced selectivity for GPS band reception. This configuration is suitable for GPS navigation applications and does not create incompatibility with existing circuit designs.

Q: Are there packaging differences between these parts?

A: The AP.10D.01 packaging is not specified in available documentation. The AP.10H.01 is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AP.10D.01 and AP.10H.01 are ROHS3 compliant and carry MSL 3 (168 Hours) moisture sensitivity ratings. Storage and handling requirements are identical.

Q: Why is AP.10D.01 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AP.10H.01 represents the active product line continuation with equivalent electrical and mechanical specifications.
