ASE-1.8432MHZ-L-R-T Equivalent & Substitute Parts

Part Overview

The ASE-1.8432MHZ-L-R-T is a 1.8432 MHz XO (Standard) CMOS oscillator manufactured by Abracon LLC. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality, housed in a 4-SMD, No Lead package. The part is Active status and ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASE-1.8432MHZ-L-R-T is determined by the following critical parameters:

• Frequency: 1.8432 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Voltage - Supply: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Current - Supply (Max): 7mA (exact match required)
• Current - Supply (Disable) (Max): 10µA (exact match required)

The ASE-1.8432MHZ-L-C-T qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The difference in frequency stability (±50ppm vs. ±25ppm) represents a relaxation of tolerance specification and does not prevent substitution in applications where the tighter stability of the main part is not required.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-1.8432MHZ-L-R-T and ASE-1.8432MHZ-L-C-T are Active status products from Abracon LLC with identical ROHS3 compliance, REACH status, and regulatory classifications. Selection between these parts should be based on application-specific frequency stability requirements and inventory availability.

The ASE-1.8432MHZ-L-R-T with ±25ppm stability is suitable for applications requiring tighter frequency tolerance. The ASE-1.8432MHZ-L-C-T with ±50ppm stability is suitable for applications where the relaxed tolerance specification is acceptable. Both parts maintain identical electrical performance in supply voltage, current consumption, enable/disable functionality, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ASE-1.8432MHZ-L-C-T replace ASE-1.8432MHZ-L-R-T in my design?

A: Yes, provided your application does not require the ±25ppm frequency stability of the main part. The substitute part meets all other electrical and mechanical specifications identically.

Q: What is the difference between these two part numbers?

A: The primary difference is frequency stability specification: ASE-1.8432MHZ-L-R-T specifies ±25ppm, while ASE-1.8432MHZ-L-C-T specifies ±50ppm. All other parameters, including frequency, voltage, current consumption, package dimensions, and operating temperature range, are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the same 4-SMD, No Lead package with dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.047" (1.20mm). They are mechanically interchangeable on the PCB.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS codes.
