ECS-24-32-1 Equivalent & Substitute Parts

Part Overview

The ECS-24-32-1 is a 2.4576 MHz through-hole crystal oscillator in HC-49/U package with 32pF load capacitance and 300 Ohms equivalent series resistance. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent substitute parts is necessary for legacy system maintenance, repair operations, and continued production support where original components are no longer readily available or have limited inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-24-32-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 2.4576 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 300 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/U (exact match required)
• Mounting Type: Through Hole (exact match required)

Two substitute parts meet these criteria. Operating temperature range and RoHS compliance status are secondary considerations that do not affect functional substitutability but influence selection based on application requirements and regulatory constraints.

Parameter Comparison

Engineering Selection Recommendations

Both ECS-24-32-1X and MP024S are functionally equivalent substitutes for the ECS-24-32-1 based on critical electrical and mechanical parameters.

ECS-24-32-1X is the direct parametric equivalent from the same manufacturer (ECS Inc.). It maintains identical specifications while offering Active product status and ROHS3 compliance. This part is preferred for applications requiring manufacturer continuity and maximum inventory availability (38,500 units in stock).

MP024S from CTS-Frequency Controls is a direct manufacturer alternative that meets all substitution criteria. It provides an extended operating temperature range (-20°C to 70°C versus -10°C to 70°C) and ROHS3 compliance. This part is suitable for applications requiring broader temperature performance or supplier diversification.

Selection between these substitutes should be based on application-specific requirements: manufacturer preference, temperature range needs, and supply chain strategy. Both parts are Active status components with current availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can ECS-24-32-1X and MP024S be used interchangeably with ECS-24-32-1?

A: Yes. Both substitute parts match the critical electrical parameters (frequency, tolerance, load capacitance, ESR) and mechanical specifications (HC-49/U package, through-hole mounting) required for direct substitution. Circuit board layout and component footprints remain compatible.

Q: What is the difference between ECS-24-32-1 and ECS-24-32-1X?

A: The ECS-24-32-1X is the current production equivalent from ECS Inc. with identical electrical and mechanical specifications. The primary differences are product status (Active versus Not For New Designs) and RoHS compliance (ROHS3 Compliant versus non-compliant). Inventory availability is significantly higher for the 1X variant.

Q: Why does MP024S have a wider operating temperature range?

A: MP024S is specified for -20°C to 70°C operation, compared to -10°C to 70°C for the ECS variants. This extended lower temperature specification is a design characteristic of the CTS-Frequency Controls MP series and does not affect substitutability for applications within the -10°C to 70°C range.

Q: Are there any physical dimension differences between these parts?

A: All three parts use the HC-49/U package with identical height specifications (0.530" maximum seated height). The ECS-24-32-1 and ECS-24-32-1X have identical length and width (0.447" L x 0.183" W). The MP024S has slightly different length and width dimensions (0.427" L x 0.150" W) but maintains the same HC-49/U package classification and through-hole mounting compatibility.

Q: What is the significance of RoHS compliance for this component?

A: RoHS3 compliance indicates the substitute parts (ECS-24-32-1X and MP024S) meet current environmental and hazardous substance restrictions. The original ECS-24-32-1 is RoHS non-compliant. For new designs or applications with regulatory requirements, the compliant substitutes are required. For legacy system repairs, compliance requirements depend on application jurisdiction and customer specifications.

Q: Which substitute part should I select for new inventory procurement?

A: Selection depends on your supply chain requirements. ECS-24-32-1X offers the highest inventory availability (38,500 units) and manufacturer continuity with ECS Inc. MP024S provides supplier diversification and extended temperature range. Both are Active status components with current manufacturing support and ROHS3 compliance.
