Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Renesas Electronics 767-125-3 is determined by strict equivalence across the following critical parameters:

Frequency matching at 125 MHz, identical HCMOS output configuration, 3.3V supply voltage requirement, Enable/Disable function capability, ±50ppm frequency stability tolerance, operating temperature range of -40°C to 85°C, 4-SMD No Lead package format, surface mount mounting type, and compliance certifications (RoHS3, REACH Unaffected, EAR99 ECCN classification).

The ECS-3963-1250-BN-TR meets all substitution criteria. Physical dimensions vary slightly (ECS: 5.00mm x 3.20mm vs. Renesas: 5.15mm x 3.35mm) and maximum supply current differs (ECS: 35mA vs. Renesas: 47mA), but these variations remain within acceptable mechanical and electrical tolerance for direct substitution in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Renesas Electronics 767-125-3 and ECS ECS-3963-1250-BN-TR are Active products with identical RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. Selection between these parts should be based on availability, lead time, and supply chain requirements. The ECS part offers lower maximum supply current (35mA vs. 47mA), which may provide marginal power efficiency benefits in applications with tight power budgets. Physical dimensions are comparable with the ECS part being slightly more compact. Both parts maintain equivalent electrical performance across all specified parameters and are suitable for direct substitution in 125 MHz HCMOS oscillator applications requiring 3.3V operation with Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can the ECS-3963-1250-BN-TR directly replace the Renesas 767-125-3 in existing designs?

A: Yes. Both parts share identical frequency (125 MHz), output type (HCMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-40°C to 85°C), and package format (4-SMD, No Lead). Physical dimensions differ slightly but remain compatible with standard PCB layouts for this package type.

Q: What are the key differences between these two parts?

A: The primary differences are maximum supply current (Renesas: 47mA, ECS: 35mA) and physical dimensions (Renesas: 5.15mm x 3.35mm, ECS: 5.00mm x 3.20mm). The ECS part is slightly more compact and draws less current. Both maintain identical electrical specifications and compliance certifications.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS3 compliant, REACH Unaffected, and classified as EAR99 under ECCN. Both share the same HTSUS code (8542.39.0001) and MSL rating (1 - Unlimited).

Q: What packaging options are available?

A: The Renesas 767-125-3 is available in standard packaging. The ECS-3963-1250-BN-TR is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Are there any temperature or frequency stability concerns with substitution?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and maintain the same frequency stability specification (±50ppm), ensuring equivalent performance in all rated operating conditions.
