Substitute Part Grouping Explanation
Substitution of the B3B-PH-SM3-TB is determined by strict equivalence across the following critical parameters:
- Connector type, contact type, and series (Header, Male Pin, PH series)
- Number of positions and pitch (3 positions, 2.00mm)
- Mounting method (Surface Mount)
- Shrouding configuration (Shrouded - 4 Wall)
- Electrical ratings (2A current, 100V voltage)
- Operating temperature range (-25°C ~ 85°C)
- Termination method (Solder)
- Mechanical dimensions (Contact length, insulation height, mated stacking height)
The B3B-PH-SM4-TB meets all these criteria and is identified as a direct substitute. Differences in contact finish material (Tin-Lead vs. Tin) and insulation material (Polyamide PA46 vs. PA6T) do not affect functional compatibility within the specified electrical and mechanical parameters. The substitute part is in active production status with full RoHS3 compliance.

Engineering Selection Recommendations
The B3B-PH-SM4-TB is the direct substitute for the obsolete B3B-PH-SM3-TB. Selection of the substitute part is supported by:
- Identical electrical and mechanical specifications across all critical parameters
- Active production status ensuring long-term availability
- RoHS3 compliance, addressing regulatory requirements that the original part does not meet
- Equivalent performance within the specified operating conditions and environmental ratings
For applications requiring RoHS compliance or long-term supply chain stability, the B3B-PH-SM4-TB is the appropriate selection. The substitute part maintains full functional compatibility with existing designs using the B3B-PH-SM3-TB.
Frequently Asked Questions (FAQ)
Q: Can the B3B-PH-SM4-TB be used as a direct replacement for the B3B-PH-SM3-TB?
A: Yes. The B3B-PH-SM4-TB is a direct substitute. Both parts share identical connector type, pitch, number of positions, mounting method, electrical ratings, and mechanical dimensions. The parts are functionally equivalent for all applications within the specified operating parameters.
Q: What are the differences between the B3B-PH-SM3-TB and B3B-PH-SM4-TB?
A: The primary differences are product status and regulatory compliance. The B3B-PH-SM3-TB is obsolete and RoHS non-compliant, while the B3B-PH-SM4-TB is in active production and RoHS3 compliant. Additionally, the contact finish material differs (Tin-Lead vs. Tin) and the insulation material composition varies (Polyamide PA46 vs. PA6T). These differences do not affect electrical or mechanical compatibility.
Q: Are there packaging differences between these parts?
A: The B3B-PH-SM3-TB packaging information is not specified. The B3B-PH-SM4-TB is available in Cut Tape (CT) and Digi-Reel® packaging options. Verify packaging requirements for your specific procurement and assembly processes.
Q: What is the pitch specification for these connectors?
A: Both parts have a mating pitch of 0.079 inches (2.00mm), which is the standard spacing between contact positions in the PH series.
Q: Are these parts suitable for high-temperature applications?
A: Both parts operate within the temperature range of -25°C to 85°C. Applications requiring operation outside this range require alternative component selection.
Q: What is the current-carrying capacity of these connectors?
A: Both parts are rated for 2A continuous current at 100V maximum voltage. Design calculations must account for these electrical limits.
