Substitute Part Grouping Explanation

Substitute parts for the 403WF12012IMR are identified based on strict equivalence of the following critical parameters:

• Frequency: 12 MHz (exact match required)
• Frequency Tolerance: ±10ppm (exact match required)
• Load Capacitance: 4pF (exact match required)
• ESR: 100 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

The ABM8W-12.0000MHZ-4-D1X-T3 from Abracon LLC meets all specified electrical and mechanical parameters, making it a direct parametric equivalent suitable for applications requiring the 403WF12012IMR.

Parameter Comparison

Engineering Selection Recommendations

Both the 403WF12012IMR and ABM8W-12.0000MHZ-4-D1X-T3 are Active products with identical electrical specifications and physical dimensions. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use. Selection between these parts may be based on packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and supplier availability. The ABM8W series carries MSL Not Applicable rating, while the 403W series specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints for either part under standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the ABM8W-12.0000MHZ-4-D1X-T3 be used as a direct replacement for the 403WF12012IMR?

A: Yes. Both parts share identical frequency (12 MHz), frequency tolerance (±10ppm), load capacitance (4pF), ESR (100 Ohms), operating mode (Fundamental), package type (4-SMD, No Lead), physical dimensions (3.20mm x 2.50mm), and operating temperature range (-40°C ~ 85°C). No circuit modifications are required.

Q: What is the difference between the packaging options?

A: The 403WF12012IMR is supplied in Tape & Reel (TR) format, while the ABM8W-12.0000MHZ-4-D1X-T3 is available in Cut Tape (CT) & Digi-Reel® format. Both packaging methods are suitable for automated assembly processes; selection depends on production equipment compatibility and order quantity requirements.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8541.60.0050 HTSUS code. No compliance barriers exist for substitution.

Q: Does moisture sensitivity affect part selection?

A: The 403WF12012IMR specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The ABM8W-12.0000MHZ-4-D1X-T3 lists MSL as Not Applicable. Both parts can be stored and handled under standard conditions without special moisture control measures.

Q: What parameters must remain identical for substitution?

A: Frequency (12 MHz), frequency tolerance (±10ppm), load capacitance (4pF), ESR (100 Ohms), operating mode (Fundamental), package type (4-SMD, No Lead), and physical dimensions (3.20mm x 2.50mm) must all match exactly. Deviations in any of these parameters disqualify a part as a direct substitute.
