Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-P145-A is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ECS-P145-AX maintains identical specifications in the following key areas: frequency range (1 MHz ~ 150 MHz), output configuration (HCMOS), supply voltage (5V), frequency stability (±100ppm), enable/disable function, package type (14-DIP, 4 Leads, Full Size Metal Can), through-hole mounting, operating temperature range (0°C ~ 70°C), maximum supply current (45mA), and moisture sensitivity level (MSL 1). Both parts are programmable oscillators with crystal base resonators and are programmed by DiGi Electronics according to specified frequency requirements. The substitute relationship is based on complete electrical and mechanical compatibility within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

The ECS-P145-A and ECS-P145-AX are electrically and mechanically equivalent programmable crystal oscillators. Both components maintain active product status and are available in new original condition with adequate inventory levels. The primary distinction between these parts is regulatory compliance: the ECS-P145-AX is ROHS3 compliant, while the ECS-P145-A is RoHS non-compliant. Selection between these parts should be based on the specific compliance requirements of the target application and end-use market. For applications requiring RoHS3 compliance, the ECS-P145-AX is the appropriate selection. For applications without RoHS compliance mandates, either part is suitable based on availability and supply chain considerations. Both parts carry identical REACH Unaffected and EAR99 ECCN designations. The ECS-P145-AX offers higher current inventory availability at 866 pieces compared to 700 pieces for the ECS-P145-A.

Frequently Asked Questions (FAQ)

Q: Are the ECS-P145-A and ECS-P145-AX pin-compatible?

A: Yes. Both parts use the 14-DIP, 4-lead full-size metal can package with identical physical dimensions (0.815" L x 0.508" W, 20.70mm x 12.90mm) and maximum seated height (0.197" / 5.00mm). They are directly interchangeable at the board level without layout modifications.

Q: What is the primary difference between these two oscillators?

A: The ECS-P145-AX is ROHS3 compliant, while the ECS-P145-A is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use either part interchangeably in my design?

A: Interchangeability depends on your application's compliance requirements. If RoHS3 compliance is mandatory, use the ECS-P145-AX. If no RoHS compliance is required, either part functions identically. Verify your end-use market and customer requirements before final selection.

Q: What frequency range is available for both parts?

A: Both the ECS-P145-A and ECS-P145-AX support programmable frequencies from 1 MHz to 150 MHz. Frequency is specified during order placement through DiGi Electronics's web order notes system.

Q: Are there any differences in operating conditions?

A: No. Both parts operate identically across the 0°C to 70°C temperature range with ±100ppm frequency stability, 5V supply voltage, 45mA maximum supply current, and Enable/Disable functionality.

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without moisture control requirements.

Q: Can these parts be used in new designs?

A: Yes. Both the ECS-P145-A and ECS-P145-AX maintain active product status and are suitable for new design implementations. The ECS-P145-AX is recommended for new designs requiring RoHS3 compliance.
