Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 2112973010 is determined by the following critical parameters:

RF Functional Compatibility: The substitute part must support 4G, GPS, and BeiDou frequency bands. The Taoglas MA140.A.LB.001 meets this requirement through its multi-band coverage including 2G, 3G, 4G, GLONASS, GPS, and LTE standards across frequency ranges of 698MHz–960MHz, 1.575GHz–1.61GHz, 1.71GHz–2.17GHz, and 2.5GHz–2.8GHz.

Environmental and Compliance Requirements: Both parts maintain MSL 1 (Unlimited) rating, ensuring equivalent moisture sensitivity performance. The substitute part carries RoHS3 compliance and REACH Unaffected status, meeting regulatory requirements for equivalent deployment.

Physical and Mechanical Compatibility: The substitute antenna is a dome-type RF antenna with panel mount configuration and SMA Male (2) termination, providing mechanical compatibility for integration into systems designed for the original part.

Performance Specifications: The substitute part delivers specified gain values (1.58dBi, 2dBic, 2.7dBi, 1.11dBi) and VSWR ratings (3, 1.5, 1.5, 3, 3) across its supported frequency bands, with maximum power handling of 5W.

Parameter Comparison

Engineering Selection Recommendations

Product Status Alignment: Both the Molex 2112973010 and Taoglas MA140.A.LB.001 maintain Active product status, ensuring continued manufacturer support and availability for production environments.

Compliance and Certification: The Taoglas MA140.A.LB.001 substitute carries RoHS3 compliance and REACH Unaffected designation, meeting regulatory requirements equivalent to or exceeding those of the original part. Both components maintain MSL 1 rating, confirming equivalent environmental performance.

Frequency Band Coverage: The substitute part extends frequency coverage beyond the original specification, supporting 2G and 3G standards in addition to 4G, GPS, and GLONASS navigation systems. This broader band support provides design flexibility for multi-standard applications.

Inventory Availability: The Taoglas MA140.A.LB.001 is available in higher inventory quantity (1889 Pcs) compared to the Molex part (907 Pcs), supporting supply chain continuity and production scheduling.

Frequently Asked Questions (FAQ)

Q: Can the Taoglas MA140.A.LB.001 directly replace the Molex 2112973010 in existing designs?

A: The Taoglas MA140.A.LB.001 provides functional RF coverage for 4G, GPS, and navigation standards required by the original part. However, physical form factor differences exist: the original is a top-stick external antenna while the substitute is a dome-type panel mount antenna. Integration feasibility depends on mechanical mounting constraints and available board space in the target application.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by frequency band coverage, gain specifications, VSWR performance, and maximum power handling. The Taoglas substitute supports the required 4G and GPS frequency bands with specified gain and VSWR values across all supported bands, meeting electrical performance requirements.

Q: Are there differences in environmental performance between these parts?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental performance. The Taoglas substitute includes IP67 ingress protection specification, providing additional environmental sealing capability not specified for the original part.

Q: What packaging considerations apply to the substitute part?

A: The Taoglas MA140.A.LB.001 is supplied in Bag packaging, compared to standard packaging for the original part. This affects receiving, storage, and handling procedures but does not impact functional performance or electrical characteristics.

Q: Does the substitute part support the same termination interface?

A: The Taoglas MA140.A.LB.001 features SMA Male (2) termination. Original part termination specifications are not provided in the reference data. Termination compatibility must be verified against the specific connector requirements of the target application.

Q: What is the significance of the extended frequency range in the substitute part?

A: The Taoglas MA140.A.LB.001 supports additional frequency bands including 2G and 3G standards beyond the 4G and GPS coverage of the original part. This extended coverage enables the substitute to function in legacy network environments and provides backward compatibility for multi-generational wireless systems.
