7M16000348 16 MHz Crystal Equivalent & Substitute Parts

Part Overview

The 7M16000348 is a 16 MHz surface mount crystal oscillator manufactured by TXC CORPORATION. This component operates at a fundamental frequency of 16 MHz with a load capacitance of 20pF and frequency stability of ±50ppm. The part is housed in a 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 0.80mm. The 7M16000348 maintains Active product status and is RoHS Compliant with MSL Level 1 (Unlimited moisture sensitivity). Substitute parts are identified when inventory constraints, lead time requirements, or supply chain considerations necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M16000348 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 16 MHz
• Frequency Stability: ±50ppm
• Load Capacitance: 20pF
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 3.20mm x 2.50mm
• Maximum Seated Height: 0.80mm
• Operating Temperature Range: -20°C ~ 70°C
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute parts identified below satisfy all mandatory matching parameters and compliance requirements. Variations in ESR (Equivalent Series Resistance) and operating mode do not preclude substitution when all electrical frequency characteristics and mechanical package specifications align.

Engineering Selection Recommendations

Both identified substitute parts satisfy the electrical and mechanical requirements for direct substitution with the 7M16000348.

ECS-160-20-33-TR (ECS Inc.): This substitute maintains all critical frequency, load capacitance, and package specifications. The part carries ROHS3 Compliant status and MSL Level 1 rating. Inventory availability is 43,300 pieces. The ESR specification of 80 Ohms is provided for this part.

RH100-16.000-20-5050-TR (Raltron Electronics): This substitute also maintains all critical frequency, load capacitance, and package specifications. The part carries ROHS3 Compliant status and MSL Level 1 rating. Inventory availability is 1,614 pieces. The ESR specification of 70 Ohms is provided for this part.

Selection between the main part and substitutes is based on availability, lead time, and supply chain requirements. All three parts are Active status components with equivalent compliance certifications and operating characteristics.

Frequently Asked Questions (FAQ)

Q: What determines whether a crystal can substitute for the 7M16000348?

A: Substitution is determined by matching frequency (16 MHz), frequency stability (±50ppm), load capacitance (20pF), package type (4-SMD, No Lead), physical dimensions (3.20mm x 2.50mm), maximum seated height (0.80mm), operating temperature range (-20°C ~ 70°C), and compliance status (RoHS Compliant, MSL Level 1, REACH Unaffected).

Q: Are the substitute parts pin-compatible with the 7M16000348?

A: Yes. All substitute parts use the same 4-SMD, No Lead package configuration with identical physical dimensions and mounting specifications, ensuring mechanical and electrical compatibility in PCB layouts designed for the 7M16000348.

Q: Does ESR variation between parts affect substitution eligibility?

A: ESR values are provided for the substitute parts (80 Ohms for ECS-160-20-33-TR and 70 Ohms for RH100-16.000-20-5050-TR) but are not specified for the main part. All parts meet the frequency stability and load capacitance requirements. ESR differences within this range do not preclude substitution when all other electrical and mechanical parameters align.

Q: What is the difference between RoHS and ROHS3 compliance?

A: The main part carries RoHS Compliant status, while both substitute parts carry ROHS3 Compliant status. Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. Both statuses satisfy RoHS compliance requirements.

Q: Can these parts be used interchangeably in production?

A: Yes. All three parts maintain Active product status, identical operating temperature ranges, and equivalent compliance certifications. They are electrically and mechanically interchangeable for applications requiring 16 MHz crystals with 20pF load capacitance in 4-SMD, No Lead packages.

Q: What is MSL Level 1 and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates Unlimited moisture sensitivity, meaning the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. All three parts carry this rating.
