Frequently Asked Questions (FAQ)

Q: Can the A-CCS 044-Z-T be used as a direct replacement for the A-CCS44-Z?

A: Yes. The A-CCS 044-Z-T is a direct manufacturer equivalent from Assmann WSW Components. Both parts share identical PLCC 44-position configuration, 0.050" mating pitch, 0.100" post pitch, tin contact finish, closed frame design, and solder termination. The substitute offers improved contact resistance and is ROHS3 compliant. The operating temperature range is reduced from -55°C ~ 105°C to -40°C ~ 105°C.

Q: What are the key differences between the three substitute parts?

A: The primary differences are manufacturer, contact material, and housing material. A-CCS 044-Z-T uses phosphor bronze contacts with PBT housing. The 54020-44030LF uses copper alloy contacts with PPS housing. The 8444-11B1-RK-TP uses copper alloy contacts with glass-filled PBT housing. All three maintain identical pin configuration, pitch specifications, and electrical ratings. Contact resistance values vary: A-CCS 044-Z-T (15mOhm), 54020-44030LF (20mOhm), and 8444-11B1-RK-TP (not specified).

Q: Are there any compatibility concerns with PCB mounting?

A: Termination post length varies slightly among substitutes: A-CCS44-Z (0.130"), A-CCS 044-Z-T (0.132"), 54020-44030LF (0.126"), and 8444-11B1-RK-TP (0.132"). These variations fall within standard PCB through-hole tolerance ranges and do not affect functional compatibility. Verify PCB design specifications if post length is a critical constraint.

Q: Which substitute offers the best RoHS compliance?

A: All three substitutes are RoHS compliant. A-CCS 044-Z-T and 8444-11B1-RK-TP are ROHS3 compliant. The 54020-44030LF is RoHS compliant. The original A-CCS44-Z is RoHS non-compliant. For applications requiring RoHS3 certification, A-CCS 044-Z-T or 8444-11B1-RK-TP are recommended.

Q: What is the operating temperature difference between the main part and substitutes?

A: The A-CCS44-Z operates from -55°C to 105°C. All three substitutes operate from -40°C to 105°C. The lower temperature limit is raised by 15°C in the substitutes. For applications requiring operation below -40°C, the original A-CCS44-Z specifications must be maintained if available.

Q: Which substitute has the best inventory availability?

A: The A-CCS 044-Z-T offers the highest inventory availability with 10233 pcs in stock, followed by 8444-11B1-RK-TP with 5655 pcs, and 54020-44030LF with 2030 pcs. The original A-CCS44-Z has 727 pcs available but is obsolete.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, all three substitutes are electrically and mechanically interchangeable with the A-CCS44-Z for PLCC 44-position socket applications. The identical pin configuration, pitch specifications, contact finish, and electrical ratings ensure functional compatibility. PCB layout and design files require no modification for substitution.
