Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPTMBP1PMCDF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Data Rate: 100Gbps
• Wavelength: 850nm
• Connector Type: MPO
• Mounting Type: Pluggable, QSFP28
• Application: Ethernet

Compatible Parameter Ranges:

• Supply Voltage: The main part operates at 3.3V. Substitute parts with supply voltage ranges that encompass 3.3V are electrically compatible.
• Moisture Sensitivity Level: MSL 1 (Unlimited) is the baseline; equivalent or superior ratings are acceptable.

The STA-100G-SR4 meets all mandatory matching parameters and operates within a supply voltage range (3.13V ~ 3.47V) that includes the 3.3V specification of the main part, establishing functional equivalence for system integration.

Engineering Selection Recommendations

Primary Substitute: STA-100G-SR4

The STA-100G-SR4 is the qualified substitute for the discontinued SPTMBP1PMCDF. Selection is based on the following engineering criteria:

1. Functional Equivalence: Both parts share identical data rate (100Gbps), wavelength (850nm), connector type (MPO), and form factor (QSFP28 pluggable).

2. Electrical Compatibility: The STA-100G-SR4 supply voltage range of 3.13V to 3.47V encompasses the 3.3V specification of the main part, ensuring direct compatibility with existing power delivery systems.

3. Product Availability: The STA-100G-SR4 maintains active product status with 1178 units in stock, providing supply continuity for ongoing production and replacement requirements.

4. Compliance Status: The STA-100G-SR4 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic components in target markets.

5. Packaging and Handling: Both parts maintain identical MSL 1 (Unlimited) ratings, eliminating moisture sensitivity considerations during storage, handling, and deployment.

Frequently Asked Questions (FAQ)

Q: Can the STA-100G-SR4 directly replace the SPTMBP1PMCDF in existing systems?

A: Yes. Both transceivers operate at 100Gbps with 850nm wavelength, use MPO connectors, and are packaged as QSFP28 pluggable modules. The STA-100G-SR4 supply voltage range (3.13V ~ 3.47V) includes the 3.3V specification of the main part, ensuring electrical compatibility without modification to host systems.

Q: Are there differences in transmission distance or performance specifications?

A: Both parts are designed for 100-meter Ethernet transmission over multimode fiber at 850nm. The provided parameters confirm functional equivalence for this application range.

Q: What is the significance of the supply voltage range on the STA-100G-SR4?

A: The STA-100G-SR4 operates across a voltage range rather than a fixed voltage. This range (3.13V ~ 3.47V) encompasses the 3.3V nominal specification of the SPTMBP1PMCDF, confirming that the substitute part functions correctly within the electrical environment of systems designed for the original part.

Q: Does the ROHS3 compliance of the STA-100G-SR4 affect compatibility?

A: No. ROHS3 compliance is a regulatory certification indicating adherence to hazardous substance restrictions. This certification does not impact electrical or mechanical compatibility and represents an equivalent or superior compliance posture compared to the original part.

Q: Are there any moisture sensitivity considerations when switching to the STA-100G-SR4?

A: No. Both parts carry identical MSL 1 (Unlimited) ratings, indicating unlimited shelf life under standard storage conditions. Handling and storage protocols remain unchanged.

Q: What is the inventory status for the substitute part?

A: The STA-100G-SR4 is currently in active production with 1178 units available in stock, providing reliable supply for immediate and ongoing requirements.
