Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-36-S-1 is determined by strict equivalence across the following critical parameters:

Frequency matching at 3.6864 MHz with identical tolerance specifications (±30ppm frequency tolerance and ±50ppm frequency stability) ensures direct functional replacement without circuit redesign. ESR specification of 120 Ohms must be maintained to preserve circuit impedance characteristics. HC-49/U package and through-hole mounting type are mandatory for mechanical and PCB layout compatibility. Operating temperature range of -10°C ~ 70°C and Series load capacitance configuration must remain constant. MSL rating of 1 (Unlimited) and identical physical dimensions (0.447" L x 0.183" W, height 0.530" max) are required for assembly process compatibility.

The ECS-36-S-1X qualifies as a parametric equivalent substitute based on complete alignment with all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ECS-36-S-1 and ECS-36-S-1X are Active status products suitable for direct substitution based on parametric equivalence. The primary distinction is RoHS compliance status: ECS-36-S-1 is RoHS non-compliant, while ECS-36-S-1X is ROHS3 Compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. Both parts carry REACH Unaffected designation and EAR99 ECCN classification. Inventory availability may also influence part selection, with ECS-36-S-1X currently showing higher stock levels (1527 Pcs vs 972 Pcs).

Frequently Asked Questions (FAQ)

Q: Can ECS-36-S-1X directly replace ECS-36-S-1 in existing designs?

A: Yes. Both parts maintain identical electrical specifications (3.6864 MHz frequency, ±30ppm tolerance, 120 Ohms ESR, Fundamental mode operation) and mechanical configuration (HC-49/U package, through-hole mounting, identical dimensions). Direct substitution is supported without circuit modification.

Q: What is the significance of the RoHS compliance difference?

A: ECS-36-S-1 is RoHS non-compliant while ECS-36-S-1X is ROHS3 Compliant. Selection depends on regulatory requirements for the target market and application. ROHS3 compliance is required for products sold in the European Union and certain other regulated markets.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both parts share identical dimensions: 0.447" L x 0.183" W (11.35mm x 4.65mm) with maximum seated height of 0.530" (13.46mm). PCB layout and mechanical assembly compatibility is maintained.

Q: What parameters must remain constant for substitution eligibility?

A: Frequency (3.6864 MHz), frequency tolerance (±30ppm), frequency stability (±50ppm), ESR (120 Ohms), operating mode (Fundamental), temperature range (-10°C ~ 70°C), package type (HC-49/U), mounting type (through-hole), and load capacitance configuration (Series) must all remain unchanged for valid substitution.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts carry MSL rating of 1 (Unlimited), indicating identical moisture handling and storage requirements.
