Frequently Asked Questions (FAQ)

Q: Can I use a 0.197" (5.00mm) pitch part as a substitute for the 0.200" (5.08mm) pitch original?

A: Yes. The 0.03mm pitch difference is within acceptable mechanical tolerance for terminal block applications. Both pitch specifications are standard in the industry and provide equivalent electrical performance. PCB layout modifications are not required for this substitution.

Q: What is the difference between 2-side and 4-side shrouded terminal blocks?

A: 2-side shrouding provides lateral protection for the connector pins. 4-side shrouding extends protection on all sides, offering enhanced EMI shielding and mechanical robustness. Both configurations are electrically equivalent and mechanically compatible with standard terminal block receptacles.

Q: Are Molex, Adam Tech, and Amphenol PCD parts interchangeable with the original TE Connectivity part?

A: Yes, when matching the specified parameters. All substitute parts listed maintain identical position count, orientation, mounting type, termination style, and flammability rating. Electrical performance is equivalent across all listed substitutes.

Q: Does the housing material change affect performance?

A: No. Polyamide (PA66), Polybutylene Terephthalate (PBT), and Polyamide (PA46) provide equivalent mechanical strength, thermal stability, and electrical insulation properties for terminal block applications. Material selection does not impact electrical functionality or compatibility.

Q: What is the significance of RoHS compliance on these parts?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. All active substitute parts are RoHS compliant, meeting current regulatory requirements for electronics manufacturing and end-of-life disposal.

Q: Can I mix substitute parts from different manufacturers in the same application?

A: Yes. All listed substitute parts meet identical electrical and mechanical specifications. Mixing parts from different manufacturers does not affect performance, provided the pitch specification remains consistent within a single connector assembly.

Q: What is the current and voltage rating for these terminal blocks?

A: All active substitute parts are rated for 15 A at 300 V (UL specification). The original obsolete part does not specify these ratings in the provided data, but the substitute parts provide this electrical performance specification.

Q: How do I determine which substitute is best for my application?

A: Selection depends on three factors: (1) PCB pitch requirement—use exact 0.200" (5.08mm) match if possible; (2) EMI shielding need—select 4-side shroud if required; (3) operating environment—all parts operate -40°C to 105°C. For standard applications without EMI concerns, Molex 0395320005 or Amphenol PCD ELFH05220 provide direct replacement.

Q: Is the contact tail length difference significant?

A: Contact tail length varies between 0.138" (3.50mm) on the original and 0.150" to 0.157" (3.81mm to 4.00mm) on substitutes. These variations are within standard PCB through-hole tolerance and do not affect mechanical or electrical performance.
