Substitute Part Grouping Explanation

The GPS-TMG-HR-26NCM has been identified as the manufacturer-recommended substitute for GPS-TMG-HR-26PMSCL-A. The substitution is based on the following alignment criteria:

• Manufacturer: Both parts are manufactured by PCTEL, Inc., ensuring consistent design philosophy and quality standards
• Application Domain: Both serve GNSS/GPS timing and navigation applications
• Antenna Classification: Both are RF antennas designed for GPS frequency bands
• Compliance Profile: Both maintain RoHS compliance, supporting modern procurement and environmental regulations
• Active Status: GPS-TMG-HR-26NCM is Active, providing long-term availability and supply chain stability

The GPS-TMG-HR-26NCM operates at 1.575 GHz center frequency with a 1.565–1.585 GHz frequency range, which aligns with standard GPS L1 band specifications. The N Type Female termination and pole mount configuration provide mechanical and electrical compatibility for typical GPS antenna installations.

Engineering Selection Recommendations

Primary Substitute: GPS-TMG-HR-26NCM

The GPS-TMG-HR-26NCM is the manufacturer-recommended equivalent and should be the primary selection for new designs or system redesigns requiring GPS antenna functionality. This part offers:

• Active product status ensuring continued availability and manufacturer support
• Full RoHS compliance meeting current regulatory requirements
• Higher inventory availability (1309 units) compared to the obsolete part
• Documented specifications for 1.575 GHz GPS L1 band operation
• Standard N Type Female connector and pole mount configuration suitable for typical GPS installations

Connector Compatibility Consideration: The original part specifies a 4.3-1 connector, while the substitute uses N Type Female. Mechanical and electrical interface verification is required during integration to ensure compatibility with existing RF transmission line infrastructure.

Frequently Asked Questions (FAQ)

Q: Why is GPS-TMG-HR-26PMSCL-A classified as obsolete?

A: The part has reached end-of-life status with PCTEL, Inc. Obsolete classification indicates that the manufacturer no longer produces this model and will not provide ongoing support or replenishment beyond existing inventory.

Q: Is GPS-TMG-HR-26NCM a direct replacement?

A: GPS-TMG-HR-26NCM is the manufacturer-recommended substitute. Both parts are PCTEL GPS antennas designed for GNSS/GPS applications. However, the connector type differs (4.3-1 versus N Type Female), requiring mechanical interface verification before deployment.

Q: What are the key differences in specifications?

A: The substitute part provides documented frequency specifications (1.575 GHz center, 1.565–1.585 GHz range) and gain rating (4.6 dBic). The original part number encodes gain (26 dB) but does not provide detailed frequency or performance data in the available documentation. Both maintain RoHS compliance and Not Applicable MSL ratings.

Q: Can I use remaining inventory of GPS-TMG-HR-26PMSCL-A?

A: Yes. The 856 units in stock can be used for existing systems or legacy applications. However, for new designs or long-term deployments, GPS-TMG-HR-26NCM is recommended due to its active status and assured supply chain continuity.

Q: What connector type should I specify for new installations?

A: GPS-TMG-HR-26NCM uses N Type Female termination with pole mount configuration. Verify that your RF transmission line and mounting infrastructure support this standard connector type before finalizing procurement.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain RoHS compliance. GPS-TMG-HR-26PMSCL-A is ROHS3 Compliant, while GPS-TMG-HR-26NCM is RoHS Compliant. Both have Not Applicable MSL ratings, indicating no moisture sensitivity concerns for storage or handling.
