Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACTPAT184-01-IP is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency band: 1.575GHz center frequency with 1.573GHz ~ 1.583GHz operating range
• Antenna type: Ceramic patch construction
• Termination interface: U.FL (UMCC) / IPEX MHF1 connector
• Mounting configuration: Surface mount
• Application domain: GPS navigation
• Electrical performance: VSWR 1.5 and return loss -10dB

Allowable Variation Parameters:

• Gain specification: Substitute parts may differ in gain performance (measured in dBic)
• Physical height: Substitute parts may have different maximum height dimensions
• Product status: Active products are acceptable replacements for obsolete models
• Packaging format: Variations in packaging (tray vs. other formats) do not affect functional compatibility

The ACTPAT182-01-IP qualifies as a direct substitute based on identical frequency specifications, antenna type, termination standard, and mounting method. Gain and physical dimensions represent acceptable engineering trade-offs within the GPS antenna category.

Engineering Selection Recommendations

ACTPAT182-01-IP as Primary Substitute:

The ACTPAT182-01-IP is the qualified equivalent for ACTPAT184-01-IP replacement. Selection rationale is based on the following engineering factors:

Product Status Alignment: The ACTPAT182-01-IP maintains active product status, ensuring continued manufacturer support, availability, and compliance documentation. The ACTPAT184-01-IP obsolete classification creates supply chain risk and limits access to technical resources.

Compliance Certification: Both parts maintain identical RoHS compliance status and MSL rating (1 - Unlimited), confirming equivalent environmental and moisture handling requirements. The ACTPAT182-01-IP includes documented REACH unaffected status, providing additional regulatory clarity.

Functional Compatibility: Identical frequency specifications (1.575GHz center, 1.573GHz ~ 1.583GHz range), antenna type (ceramic patch), termination interface (U.FL/IPEX MHF1), and mounting configuration (surface mount) establish direct functional equivalence for GPS navigation applications.

Performance Trade-off: The ACTPAT182-01-IP exhibits reduced gain (1dBic vs. 2.5dBic) and lower physical profile (4.90mm vs. 7.00mm). These differences represent acceptable engineering trade-offs within GPS antenna performance parameters. System-level gain requirements must be evaluated against the 1.5dBic gain differential.

Inventory Availability: The ACTPAT182-01-IP demonstrates superior stock availability (1715 pcs vs. 790 pcs), supporting procurement reliability and lead time reduction.

Frequently Asked Questions (FAQ)

Q: Can ACTPAT182-01-IP directly replace ACTPAT184-01-IP in existing GPS applications?

A: Yes. Both antennas operate at identical center frequency (1.575GHz) with matching frequency range (1.573GHz ~ 1.583GHz), VSWR (1.5), return loss (-10dB), and termination interface (U.FL/IPEX MHF1). The primary difference is gain specification (1dBic vs. 2.5dBic). System performance must be evaluated to confirm the 1.5dBic gain reduction is acceptable for the application.

Q: What is the physical dimension difference between these parts?

A: ACTPAT184-01-IP maximum height is 0.276" (7.00mm). ACTPAT182-01-IP maximum height is 0.193" (4.90mm). The substitute part is 2.10mm shorter, which may provide advantages in space-constrained PCB layouts.

Q: Are the connector types identical?

A: Yes. Both parts use U.FL (UMCC) / IPEX MHF1 surface mount termination with 63mm integrated cable and LNA. No connector adapter or modification is required for substitution.

Q: Does the gain difference affect GPS signal reception?

A: Gain difference (1dBic vs. 2.5dBic) represents a 1.5dB reduction in antenna directivity. GPS receiver performance depends on system-level link budget, including receiver sensitivity, signal path losses, and environmental conditions. Engineering analysis of the specific application is required to determine if this gain reduction impacts acquisition or tracking performance.

Q: What is the product status significance?

A: ACTPAT184-01-IP is classified as obsolete, indicating discontinued manufacturing and limited manufacturer support. ACTPAT182-01-IP maintains active status, ensuring ongoing availability, technical documentation, and compliance certifications. Active status is preferred for new designs and long-term supply chain stability.

Q: Are packaging differences significant?

A: ACTPAT184-01-IP uses standard packaging; ACTPAT182-01-IP is supplied in tray packaging. Packaging format does not affect electrical or mechanical performance. Tray packaging may provide handling and storage advantages in high-volume manufacturing environments.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both ACTPAT184-01-IP and ACTPAT182-01-IP are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level). No additional environmental qualification is required for substitution.
