ECS-P85-B Equivalent & Substitute Parts

Part Overview

The ECS-P85-B is an XO (Standard) programmable crystal oscillator manufactured by ECS Inc. This component operates across a frequency range of 1 MHz to 150 MHz with HCMOS output, 5V supply voltage, and Enable/Disable functionality. The device is housed in an 8-DIP, 4 Leads (Half Size, Metal Can) through-hole package with a frequency stability of ±50ppm and maximum supply current of 45mA. The ECS-P85-B maintains Active product status and is currently available in inventory. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying compliance requirements across different manufacturing and regulatory environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-P85-B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters: Frequency range (1 MHz ~ 150 MHz), output type (HCMOS), supply voltage (5V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (0°C ~ 70°C), and maximum supply current (45mA).

Mechanical Parameters: Package type (8-DIP, 4 Leads Half Size Metal Can), mounting method (Through Hole), physical dimensions (0.520" L x 0.520" W / 13.20mm x 13.20mm), and maximum seated height (0.213" / 5.40mm).

Functional Parameters: Base resonator type (Crystal), oscillator type (XO Standard), and programmable configuration method (Programmed by DiGi Electronics).

Environmental Parameters: Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH status (REACH Unaffected).

The ECS-P85-BX qualifies as a direct substitute based on complete alignment with all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-P85-B and ECS-P85-BX are Active products from ECS Inc. with complete electrical and mechanical equivalence. The primary distinction between these parts is regulatory compliance status.

ECS-P85-B is RoHS non-compliant and suitable for applications where RoHS compliance is not required or where legacy component specifications are mandated.

ECS-P85-BX is ROHS3 compliant and is the appropriate selection for designs requiring adherence to Restriction of Hazardous Substances (RoHS) directives. This part is preferred for new designs, commercial applications subject to RoHS regulations, and supply chains requiring modern compliance certifications.

Both parts maintain identical electrical performance, frequency stability, operating temperature range, and physical package specifications. Selection between these parts should be based solely on the regulatory compliance requirements of the target application and end-use market.

Frequently Asked Questions (FAQ)

Q: Can the ECS-P85-BX be used as a direct replacement for the ECS-P85-B in existing designs?

A: Yes. The ECS-P85-BX is electrically and mechanically equivalent to the ECS-P85-B. All critical parameters including frequency range, output type, supply voltage, stability, operating temperature, current consumption, and physical package dimensions are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the ECS-P85-B and ECS-P85-BX?

A: The primary difference is RoHS compliance status. The ECS-P85-B is RoHS non-compliant, while the ECS-P85-BX is ROHS3 compliant. All other electrical, mechanical, and functional specifications are identical.

Q: Are both parts available in the same frequency range?

A: Yes. Both the ECS-P85-B and ECS-P85-BX support the same programmable frequency range of 1 MHz to 150 MHz. Both are programmed by DiGi Electronics according to customer frequency specifications entered in Web Order Notes.

Q: Do these parts have the same physical dimensions and mounting requirements?

A: Yes. Both parts use the 8-DIP, 4 Leads (Half Size, Metal Can) through-hole package with identical dimensions of 0.520" L x 0.520" W (13.20mm x 13.20mm) and maximum seated height of 0.213" (5.40mm). They are mechanically interchangeable on PCBs designed for either part.

Q: Which part should I select for a new design?

A: For new designs, the ECS-P85-BX is recommended due to its ROHS3 compliance status. This ensures compatibility with current regulatory requirements and modern supply chain standards. The ECS-P85-B should be selected only when RoHS non-compliance is specifically required by design specifications or legacy system requirements.

Q: Are both parts subject to the same environmental and regulatory restrictions?

A: Both parts have identical REACH status (REACH Unaffected) and Moisture Sensitivity Level (MSL 1 - Unlimited). The distinction is RoHS compliance: ECS-P85-B is non-compliant, while ECS-P85-BX is ROHS3 compliant. Both carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
