Substitute Part Grouping Explanation

Substitution eligibility for the TP3404V is determined by strict equivalence across the following critical parameters:

• Function: Quad Digital Adapter for Subscriber Loops (QDASL)
• Interface: ISDN
• Number of Circuits: 4
• Package / Case: 28-LCC (J-Lead)
• Supplier Device Package: 28-PLCC (11.51x11.51)
• Voltage - Supply: 4.75V ~ 5.25V
• Current - Supply: 75mA
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount

The substitute part TP3404V/NOPB meets all electrical and mechanical parameters required for direct substitution. Both parts share identical functional specifications, pinout configurations, and package dimensions, enabling seamless integration into existing designs and legacy systems.

Parameter Comparison

Engineering Selection Recommendations

The TP3404V/NOPB is a direct functional equivalent to the TP3404V. Both parts are classified as obsolete and share identical electrical and mechanical specifications across all critical parameters including voltage supply range, current consumption, operating temperature, package configuration, and circuit count.

The primary distinction between these parts is regulatory compliance status. The TP3404V/NOPB carries ROHS3 compliance, whereas the original TP3404V is RoHS non-compliant. Additionally, the TP3404V/NOPB specifies a higher moisture sensitivity level (MSL 3 at 168 hours) compared to the TP3404V (MSL 2A at 4 weeks), which may impact storage and handling requirements depending on manufacturing environment conditions.

For applications where RoHS compliance is required or preferred, the TP3404V/NOPB is the appropriate selection. For legacy systems with no compliance requirements, either part provides equivalent functional performance.

Frequently Asked Questions (FAQ)

Q: Can TP3404V/NOPB be used as a direct replacement for TP3404V?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including ISDN interface capability, four-circuit configuration, 28-PLCC package dimensions, voltage supply range (4.75V ~ 5.25V), current consumption (75mA), and operating temperature range (0°C ~ 70°C).

Q: What is the difference between TP3404V and TP3404V/NOPB?

A: The primary differences are RoHS compliance status and moisture sensitivity level. The TP3404V/NOPB is ROHS3 compliant with MSL 3 (168 hours), while the TP3404V is RoHS non-compliant with MSL 2A (4 weeks). Functional performance and electrical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 28-PLCC (11.51x11.51) package with 28-LCC (J-Lead) case configuration. Pinout and physical dimensions are identical, enabling direct board-level substitution without layout modifications.

Q: Why is the TP3404V classified as obsolete?

A: The TP3404V is an obsolete product from Texas Instruments. The TP3404V/NOPB represents the current equivalent offering with updated compliance certifications.

Q: What are the storage and handling requirements for these parts?

A: The TP3404V/NOPB has a moisture sensitivity level of MSL 3, requiring storage at controlled humidity for up to 168 hours before soldering. The original TP3404V specifies MSL 2A with a 4-week storage window. Verify specific storage conditions with your component supplier based on the part variant selected.

Q: Are both parts REACH compliant?

A: Yes. Both TP3404V and TP3404V/NOPB are listed as REACH Unaffected, indicating compliance with REACH regulations.
