ASDMB-8.000MHZ-XY-T Equivalent & Substitute Parts

Part Overview

The ASDMB-8.000MHZ-XY-T is an 8 MHz MEMS oscillator manufactured by Abracon LLC, featuring LVCMOS output with standby power-down functionality. This component operates across a 1.8V to 3.3V supply range and is housed in a compact 4-SMD, No Lead package measuring 2.50mm × 2.00mm. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when packaging format or frequency stability requirements differ from the primary specification while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the ASDMB-8.000MHZ-XY-T are qualified based on the following criteria:

Electrical Compatibility Requirements:

Identical frequency: 8 MHz
Identical output type: LVCMOS
Identical supply voltage range: 1.8V ~ 3.3V
Identical maximum supply current: 16mA
Identical disable current: 15µA
Identical package type: 4-SMD, No Lead
Identical physical dimensions: 2.50mm × 2.00mm × 0.90mm

Allowable Variations:

Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
Frequency stability tolerance (±10ppm vs. ±50ppm)
Operating temperature upper limit (-40°C ~ 105°C vs. -40°C ~ 85°C)

The ASDMB-8.000MHZ-XY-T has two qualified substitutes: ASDMB-8.000MHZ-LY-T and ASDMB-8.000MHZ-LC-T. Both maintain identical electrical performance and physical form factor while differing in packaging delivery method and, in one case, frequency stability specification.

Engineering Selection Recommendations

All three parts—ASDMB-8.000MHZ-XY-T, ASDMB-8.000MHZ-LY-T, and ASDMB-8.000MHZ-LC-T—maintain Active product status and are ROHS3 compliant with identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Selection Criteria:

The ASDMB-8.000MHZ-XY-T is the primary specification with ±10ppm frequency stability and -40°C ~ 105°C operating range. This part is suitable for applications requiring extended high-temperature operation and tighter frequency tolerance.

The ASDMB-8.000MHZ-LY-T is electrically identical to the primary part with identical frequency stability (±10ppm) and differs only in packaging format (Tape & Reel). This substitute is appropriate when Tape & Reel packaging is preferred for automated assembly processes.

The ASDMB-8.000MHZ-LC-T operates within a reduced temperature range (-40°C ~ 85°C) and has relaxed frequency stability (±50ppm). This substitute is suitable for applications where the extended temperature range and tighter stability of the primary part are not required, and Cut Tape packaging is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ASDMB-8.000MHZ-LC-T replace ASDMB-8.000MHZ-XY-T in all applications?

A: No. The ASDMB-8.000MHZ-LC-T has a reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 105°C) and relaxed frequency stability (±50ppm versus ±10ppm). Substitution is valid only for applications that do not require operation above 85°C or the tighter ±10ppm stability specification.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging provides components on a continuous reel suitable for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in smaller quantities on cut tape segments, suitable for lower-volume production or manual assembly. Both formats contain identical components in the same 4-SMD, No Lead package.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the identical 4-SMD, No Lead package with dimensions of 2.50mm × 2.00mm × 0.90mm and are pin-compatible for PCB layout purposes.

Q: Do all substitutes have the same electrical performance?

A: ASDMB-8.000MHZ-XY-T and ASDMB-8.000MHZ-LY-T have identical electrical specifications. ASDMB-8.000MHZ-LC-T differs in frequency stability (±50ppm versus ±10ppm) and maximum operating temperature (85°C versus 105°C).

Q: Are all parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and identical regulatory certifications.
