MPC962305EF-1HR2 Equivalent & Substitute Parts

Part Overview

The MPC962305EF-1HR2 is a Fanout Buffer (Distribution) Zero Delay Buffer IC manufactured by Renesas Electronics Corporation. This 8-SOIC surface mount device operates at a maximum frequency of 133.33MHz with a 1:5 input-to-output ratio, designed for clock distribution applications requiring LVCMOS signal levels. The product is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MPC962305EF-1HR2 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) — ensures mechanical and electrical pin compatibility
• Ratio - Input:Output: 1:5 — maintains functional distribution capability
• Voltage - Supply: 3V ~ 3.6V — ensures power supply compatibility
• Frequency - Max: ≥133.33MHz — guarantees operational frequency support
• Type: Zero Delay Buffer or Fanout Buffer — confirms functional equivalence

Acceptable Parameter Variations:

• Input/Output signal types may vary (LVCMOS, LVTTL, CMOS, TTL) provided the receiving circuit supports the output levels
• Operating temperature range may differ; selection depends on application requirements
• Moisture Sensitivity Level (MSL) may vary; handling procedures must be adjusted accordingly
• Product status may transition from obsolete to active, improving availability

Two substitute parts meet these criteria: the 2305-1HDCG8 (Renesas Electronics Corporation, active status) and the SL2305SI-1H (Skyworks Solutions Inc., obsolete status).

Parameter Comparison

Engineering Selection Recommendations

2305-1HDCG8 (Renesas Electronics Corporation): This part is the primary substitute option. It maintains identical supply voltage (3V ~ 3.6V), package configuration (8-SOIC), and input-to-output ratio (1:5). The maximum frequency of 133MHz meets the operational requirement of 133.33MHz. The part holds active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance provides environmental regulatory alignment. The operating temperature range (0°C ~ 70°C) is narrower than the original part; applications requiring extended temperature operation below 0°C or above 70°C must be evaluated separately. Moisture Sensitivity Level 1 (Unlimited) offers superior handling flexibility compared to the original MSL 3 specification.

SL2305SI-1H (Skyworks Solutions Inc.): This part provides an alternative substitute with identical supply voltage, package, and input-to-output ratio. The maximum frequency of 140MHz exceeds the original specification, providing operational margin. Operating temperature range (-40°C ~ 85°C) matches the original part exactly. However, the product is classified as obsolete, limiting long-term procurement viability. Moisture Sensitivity Level 2A (4 Weeks) requires more stringent handling procedures than the 2305-1HDCG8 but is less demanding than the original MSL 3.

For new designs and long-term support, the 2305-1HDCG8 is the recommended substitute due to active product status and RoHS3 compliance. The SL2305SI-1H serves as a secondary option when the 2305-1HDCG8 is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 2305-1HDCG8 directly replace the MPC962305EF-1HR2 in existing designs?

A: Yes, the 2305-1HDCG8 is mechanically and electrically compatible. Both parts use the 8-SOIC package, operate at 3V ~ 3.6V supply voltage, and provide 1:5 input-to-output distribution. The input signal type differs (LVTTL vs. LVCMOS), but LVTTL inputs accept LVCMOS signal levels. The output supports LVCMOS, matching the original specification. Verify that the operating temperature range (0°C ~ 70°C) meets application requirements.

Q: What is the significance of the different operating temperature ranges?

A: The MPC962305EF-1HR2 and SL2305SI-1H operate from -40°C to 85°C, while the 2305-1HDCG8 operates from 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use the SL2305SI-1H or the original part. Applications within the 0°C to 70°C range can use any of the three parts.

Q: How do the different Moisture Sensitivity Levels affect component handling?

A: Moisture Sensitivity Level (MSL) determines the maximum time a component can remain outside controlled humidity conditions after packaging. The original MPC962305EF-1HR2 (MSL 3, 168 hours) requires more careful handling than the 2305-1HDCG8 (MSL 1, unlimited). The SL2305SI-1H (MSL 2A, 4 weeks) falls between these two. Lower MSL values provide greater flexibility in storage and handling procedures.

Q: Are there differences in signal compatibility between the substitute parts?

A: The MPC962305EF-1HR2 accepts LVCMOS input and produces LVCMOS output. The 2305-1HDCG8 accepts LVTTL input and can produce CMOS, LVCMOS, or TTL output. LVTTL inputs are compatible with LVCMOS signal levels, and LVCMOS output is available. The SL2305SI-1H accepts Clock input and produces LVCMOS output. All three parts are compatible with standard 3.3V logic systems.

Q: What is the advantage of the 2305-1HDCG8 regarding product status?

A: The 2305-1HDCG8 holds active product status, meaning the manufacturer continues production and supports the part. This ensures long-term availability, stable pricing, and access to technical support. Both the MPC962305EF-1HR2 and SL2305SI-1H are obsolete, indicating discontinued production and potential supply constraints.

Q: Does the higher maximum frequency of the SL2305SI-1H provide any advantage?

A: The SL2305SI-1H operates at 140MHz maximum frequency, compared to 133.33MHz for the original part and 133MHz for the 2305-1HDCG8. This provides operational margin but does not enhance performance in applications designed for 133MHz operation. The frequency difference is not a determining factor for substitution in this application.
