403WF30012IMR 30 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 403WF30012IMR is a 30 MHz fundamental mode crystal manufactured by CTS-Frequency Controls, designed for surface mount applications requiring precise frequency control. This Active product is specified at ±10ppm frequency tolerance with 4pF load capacitance and 40 Ohms equivalent series resistance (ESR). The component is packaged in a 4-SMD, No Lead configuration measuring 3.20mm × 2.50mm with a maximum seated height of 0.75mm.

Equivalent and substitute parts are identified when designs require alternative sourcing, inventory optimization, or when the primary manufacturer part becomes unavailable while maintaining functional compatibility within the specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the 403WF30012IMR is determined by strict equivalence in the following critical parameters:

• Frequency: 30 MHz (exact match required)
• Frequency Tolerance: ±10ppm (exact match required)
• Load Capacitance: 4pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)

Substitute parts are classified into two categories based on ESR and physical dimensions:

Parametric Equivalent (ESR 40 Ohms, Identical Dimensions): ABM8W-30.0000MHZ-4-D1X-T3 matches all critical electrical parameters and physical footprint of the 403WF30012IMR.

Compatible Substitutes (ESR Variation, Smaller Footprint): ABM10W-30.0000MHZ-4-D1X-T3 (60 Ohms ESR, 2.50mm × 2.00mm) and ABM11W-30.0000MHZ-4-D1X-T3 (80 Ohms ESR, 2.00mm × 1.60mm) maintain all critical electrical specifications while offering reduced physical dimensions and higher ESR values.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical and Mechanical Specifications): The ABM8W-30.0000MHZ-4-D1X-T3 is the parametric equivalent to the 403WF30012IMR, matching all critical electrical parameters and physical dimensions. Both components are ROHS3 Compliant and Active products suitable for direct substitution in existing designs without PCB layout modifications.

Space-Optimized Alternatives: The ABM10W-30.0000MHZ-4-D1X-T3 and ABM11W-30.0000MHZ-4-D1X-T3 provide reduced footprint options while maintaining all critical electrical specifications. These alternatives are suitable for designs where PCB real estate optimization is required. The increased ESR values (60 Ohms and 80 Ohms respectively) remain within acceptable operating parameters for 30 MHz fundamental mode crystal applications.

All substitute parts maintain ROHS3 Compliance and Active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ABM10W-30.0000MHZ-4-D1X-T3 or ABM11W-30.0000MHZ-4-D1X-T3 be used as direct drop-in replacements for 403WF30012IMR?

A: The ABM10W and ABM11W series maintain all critical electrical specifications (frequency, tolerance, load capacitance, operating temperature range) required for functional compatibility. However, their reduced physical dimensions (2.50mm × 2.00mm and 2.00mm × 1.60mm respectively) require PCB footprint verification before implementation. The increased ESR values do not affect circuit operation within the specified frequency and temperature parameters.

Q: What is the significance of ESR variation among these parts?

A: ESR (Equivalent Series Resistance) affects crystal startup characteristics and power consumption in oscillator circuits. The 403WF30012IMR and ABM8W-30.0000MHZ-4-D1X-T3 both specify 40 Ohms ESR. The ABM10W (60 Ohms) and ABM11W (80 Ohms) variants have higher ESR values. Circuit design must accommodate these ESR specifications; however, all values remain within acceptable ranges for 30 MHz fundamental mode operation.

Q: Are there any compliance or regulatory differences between these parts?

A: All parts are ROHS3 Compliant and carry EAR99 ECCN classification. The 403WF30012IMR specifies MSL 1 (Unlimited), while Abracon substitutes list MSL as Not Applicable. This difference does not affect functional compatibility or regulatory compliance for end-use applications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on PCB layout constraints and ESR requirements. For designs with existing footprints matching 3.20mm × 2.50mm dimensions, the ABM8W-30.0000MHZ-4-D1X-T3 provides identical electrical and mechanical specifications. For space-constrained applications, the ABM10W or ABM11W series offer reduced footprints while maintaining all critical electrical parameters.
