SN10GE156 Equivalent & Substitute Parts

Part Overview

The SN10GE156 is a 156.25 MHz XO (Standard) PECL Oscillator manufactured by Diodes Incorporated, designed for applications requiring precision frequency generation with enable/disable functionality. Operating at 3.3V supply voltage with ±50ppm frequency stability, this component is housed in a 6-SMD, No Lead package measuring 7.00mm x 5.00mm.

The SN10GE156 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this oscillator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN10GE156 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• Frequency: 156.25 MHz (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Base Resonator Type: Crystal XO (Standard)

Secondary Compatibility Factors:

• Output signal type (PECL or LVPECL acceptable for signal-level compatibility)
• Enable/Disable functionality (where applicable)
• RoHS and REACH compliance status
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria: the NX72F62009 (manufacturer-recommended alternative) and the ECS-PEC33-1562.5-BN (direct equivalent from alternative manufacturer).

Parameter Comparison

Engineering Selection Recommendations

NX72F62009 (Diodes Incorporated - Manufacturer Recommended): This part is the manufacturer-recommended substitute, maintaining the same manufacturer lineage within the Diodes Incorporated product portfolio. It operates at identical frequency, voltage, and temperature specifications. The primary difference is the output type (LVPECL versus PECL), which represents a lower-voltage variant of the same signal family. This part carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection of this part is appropriate when maintaining single-manufacturer sourcing is a design priority.

ECS-PEC33-1562.5-BN (ECS Inc. - Direct Equivalent): This part provides a direct functional equivalent with identical PECL output type, enable/disable functionality, and frequency stability specification (±50ppm). It matches all critical mechanical and electrical parameters of the original SN10GE156. The maximum supply current specification (90mA) is higher than the original (70mA), which may require verification in power budget calculations for current-constrained applications. This part carries Active product status and ROHS3 compliance. Selection of this part is appropriate when direct output-type matching and frequency stability specification are design requirements.

Both substitute parts are suitable for replacing the obsolete SN10GE156 based on provided specifications and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the NX72F62009 replace the SN10GE156 directly in the circuit?

A: The NX72F62009 matches all critical electrical and mechanical parameters (frequency, voltage, temperature range, package dimensions). The output type difference (LVPECL versus PECL) represents a signal-level variant within the same family. Direct substitution is possible if the receiving circuit is designed to accept LVPECL signal levels. Verification of signal integrity with the downstream receiver is recommended during design validation.

Q: What is the difference between PECL and LVPECL outputs?

A: Both are differential signal standards. PECL (Positive Emitter Coupled Logic) and LVPECL (Low Voltage PECL) differ in signal voltage levels. LVPECL operates at lower voltage swings, reducing power consumption. Compatibility depends on the input specifications of the receiving circuit. The ECS-PEC33-1562.5-BN maintains the original PECL output type for direct signal compatibility.

Q: Are both substitute parts available in the same packaging?

A: The ECS-PEC33-1562.5-BN explicitly matches the 6-SMD, No Lead package with 7.00mm x 5.00mm dimensions. The NX72F62009 maintains the same package dimensions (7.00mm x 5.00mm). Both parts are surface-mount compatible with the original PCB layout.

Q: What is the impact of the higher supply current in the ECS-PEC33-1562.5-BN?

A: The ECS-PEC33-1562.5-BN specifies maximum supply current of 90mA compared to 70mA for the SN10GE156. This 20mA difference should be evaluated against the power supply capacity and thermal design of the application. For current-constrained systems, the NX72F62009 may be preferable if supply current specifications are available.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the NX72F62009 and ECS-PEC33-1562.5-BN carry ROHS3 compliance certification, meeting current regulatory requirements. The original SN10GE156 carried RoHS Compliant status. All three parts are REACH Unaffected.

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

A: For new designs, either Active-status substitute part is appropriate. The ECS-PEC33-1562.5-BN provides direct output-type matching and explicit frequency stability specification. The NX72F62009 offers manufacturer continuity within the Diodes Incorporated product line. Selection should be based on circuit requirements for output signal type, power budget constraints, and supply chain preferences.
