Engineering Selection Recommendations

The ASEMPLV-156.250MHZ-LR-T is the qualified substitute for the obsolete ASEMPLV-156.250MHZ-EC-T. Both parts maintain identical electrical and mechanical specifications for frequency, output type, supply voltage, function, and package form factor, ensuring direct compatibility at the circuit board level.

The substitute part offers enhanced specifications: frequency stability improves from ±50ppm to ±25ppm, operating temperature range expands from -20°C to 70°C to -40°C to 85°C, and current supply ratings increase marginally. These improvements do not introduce incompatibility and are suitable for applications requiring the original part's performance envelope.

Both parts maintain equivalent compliance certifications: ROHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications. The substitute part's Active product status ensures procurement availability and manufacturer support for new designs and production replenishment.

Frequently Asked Questions (FAQ)

Q: Can the ASEMPLV-156.250MHZ-LR-T be used as a direct replacement for the ASEMPLV-156.250MHZ-EC-T?

A: Yes. Both parts share identical frequency (156.25 MHz), output type (LVDS), supply voltage range (2.25V ~ 3.6V), function (Enable/Disable), and package specifications (6-SMD, No Lead, 3.20mm × 2.50mm). The substitute part is electrically and mechanically compatible without circuit modification.

Q: What are the key differences between these parts?

A: The substitute part provides improved frequency stability (±25ppm versus ±50ppm), expanded operating temperature range (-40°C to 85°C versus -20°C to 70°C), and slightly higher current ratings. The substitute maintains Active product status, ensuring ongoing availability.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, Moisture Sensitivity Level 1, REACH Unaffected status, and matching ECCN and HTSUS classifications.

Q: Does the improved frequency stability of the substitute part affect circuit design?

A: No. The substitute part's tighter frequency tolerance (±25ppm) is a performance improvement that does not require design changes. Circuits designed for the original ±50ppm specification will operate within acceptable parameters with the substitute part.

Q: Is the substitute part available in the same packaging format?

A: Yes. The ASEMPLV-156.250MHZ-LR-T is available in Cut Tape (CT) and Digi-Reel® packaging, maintaining the same 6-SMD, No Lead surface mount package and footprint dimensions as the original part.
