Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3ATMZ-HT are identified based on the following substitution criteria:

Primary Substitution Criteria:

• Transceiver Module category classification
• ROHS3 compliance or equivalent environmental certification
• Moisture Sensitivity Level compatibility (MSL 1)
• Pluggable, SFP+ mounting type
• LC connector configuration
• Operating voltage range compatibility

Substitute Classification:

1. MFR Recommended Substitute: AFCT-57G5MZ (Broadcom Limited) – Active product status with enhanced specifications
2. Similar Substitute: AFCT-57F3ATMZ-HT-C (ATGBICS) – Direct form-factor equivalent with active product status

Both substitutes maintain the core transceiver module functionality and physical form factor while offering active product support and availability.

Parameter Comparison

Engineering Selection Recommendations

For Broadcom Limited Ecosystem Continuity:

The AFCT-57G5MZ is the manufacturer-recommended substitute. This part maintains Broadcom Limited manufacturing lineage, carries Active product status, and provides ROHS3 compliance identical to the original component. The higher data rate specification (28.05Gbps versus unspecified original) and dual-voltage supply range (3.1V ~ 3.5V) provide enhanced operational flexibility. Unlimited MSL rating ensures equivalent handling and storage requirements.

For Form-Factor and Voltage Compatibility:

The AFCT-57F3ATMZ-HT-C provides direct part-number similarity and maintains the same wavelength specification (1310nm). This substitute carries Active product status and RoHS compliance. The fixed 3.3V supply specification and lower data rate (16Gbps) require verification against system voltage regulation and bandwidth requirements. Significantly higher inventory availability (10711 units) supports procurement continuity.

Selection Basis:

• Both substitutes are Active products with current manufacturer support
• Both maintain SFP+ pluggable form factor and LC connector configuration
• Both comply with environmental and RoHS standards
• Voltage supply specifications differ and must be evaluated against system design parameters
• Data rate specifications differ and must be evaluated against link requirements

Frequently Asked Questions (FAQ)

Q: Why is the AFCT-57F3ATMZ-HT classified as Obsolete?

A: The AFCT-57F3ATMZ-HT has reached end-of-life status with Broadcom Limited. Manufacturer support, design updates, and new production have been discontinued. Substitute parts provide equivalent functionality with active manufacturer support.

Q: What is the primary difference between the two substitute options?

A: The AFCT-57G5MZ is the manufacturer-recommended substitute from Broadcom Limited with higher data rate capability (28.05Gbps). The AFCT-57F3ATMZ-HT-C is a similar substitute from ATGBICS with lower data rate (16Gbps) but significantly higher inventory availability.

Q: Are the substitute parts pin-compatible with the original AFCT-57F3ATMZ-HT?

A: Both substitutes maintain the SFP+ pluggable form factor and LC connector configuration. Physical compatibility is established through these standardized interfaces. Electrical compatibility requires verification of voltage supply specifications against system design parameters.

Q: What is the significance of the MSL rating difference?

A: The original part and AFCT-57G5MZ both carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The AFCT-57F3ATMZ-HT-C lists MSL as Not Applicable, indicating different moisture handling classification. This difference does not affect functional compatibility but may impact storage protocol requirements.

Q: Can I use either substitute interchangeably?

A: Interchangeability depends on system-specific requirements for data rate and supply voltage. The AFCT-57G5MZ supports higher data rates (28.05Gbps) and wider voltage range (3.1V ~ 3.5V). The AFCT-57F3ATMZ-HT-C operates at fixed 3.3V with 16Gbps data rate. System design parameters must determine which substitute is appropriate.

Q: What packaging format is used for the substitute parts?

A: Both substitute parts are supplied in Tray packaging. Original packaging specification for AFCT-57F3ATMZ-HT was not provided in technical documentation.

Q: Are both substitutes RoHS compliant?

A: Yes. AFCT-57G5MZ carries ROHS3 compliance identical to the original part. AFCT-57F3ATMZ-HT-C carries RoHS compliance. Both meet environmental regulatory requirements for electronic component manufacturing and use.
