Engineering Selection Recommendations

PBC16DAAN - Recommended for direct substitution where mechanical envelope constraints allow. This part maintains active product status, offers higher inventory availability (1459 units), and meets all critical electrical and mechanical parameters. The contact post length of 0.120" (3.05mm) is slightly shorter than the main part but remains within acceptable tolerance for standard through-hole PCB applications. ROHS3 compliance exceeds RoHS requirements.

PBC16DACN - Suitable for applications requiring extended post length (0.320" / 8.13mm) for deeper PCB penetration or specialized mounting configurations. Maintains active status and full compliance. Use only where the increased overall contact length (0.650" / 16.51mm) does not create mechanical interference with adjacent components or board features.

PBC16DAGN - Provides maximum post length (0.720" / 18.29mm) for applications requiring extended insertion depth. This part is discontinued at DiGi Electronics; use only if existing inventory is available and long-term supply is not required. Verify mechanical compatibility before selection due to significantly increased overall contact length (1.050" / 26.67mm).

PEC16DAAN - Recommended where tin mating contact finish is acceptable or preferred over gold. This part offers the highest inventory availability (3457 units) and maintains active product status. The tin contact finish (100.0µin / 2.54µm) provides adequate corrosion resistance for standard applications. Select this option when gold plating is not a design requirement and cost optimization is a consideration.

All substitute parts maintain UL94 V-0 flammability rating, 3A current rating per contact, and -65°C minimum operating temperature. Operating temperature maximum is 125°C for all Sullins substitutes versus 130°C for the main part; verify application requirements do not exceed 125°C continuous operation.

Frequently Asked Questions (FAQ)

Q: Can PBC16DAAN be used as a direct drop-in replacement for 77313-102-32LF?

A: PBC16DAAN is electrically and mechanically compatible for standard through-hole PCB applications. The contact post length difference (0.120" versus 0.135") is within typical PCB tolerance ranges. Verify that the slightly shorter post length does not create insufficient solder joint depth for your specific PCB thickness and design requirements.

Q: What is the difference between the four substitute parts?

A: The primary differences are contact post length and contact finish. PBC16DAAN and PEC16DAAN have short posts (0.120" / 3.05mm), PBC16DACN has medium posts (0.320" / 8.13mm), and PBC16DAGN has long posts (0.720" / 18.29mm). PEC16DAAN uses tin mating finish instead of gold. Select based on your PCB thickness and contact finish requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part is RoHS Compliant, and all four substitute parts are ROHS3 Compliant, which exceeds RoHS requirements and ensures compatibility with RoHS-regulated applications.

Q: Can I use PBC16DAGN if I need maximum insertion depth?

A: PBC16DAGN provides the longest post length (0.720" / 18.29mm) and is suitable for applications requiring deep PCB penetration. However, this part is discontinued at DiGi Electronics. Confirm availability through alternative distributors and verify that the overall contact length of 1.050" (26.67mm) does not create mechanical interference with board layout or adjacent components.

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

A: The main part operates from -65°C to 130°C. All Sullins substitute parts operate from -65°C to 125°C. If your application requires continuous operation above 125°C, the main part 77313-102-32LF is required.

Q: Should I select PEC16DAAN for cost savings?

A: PEC16DAAN offers the highest inventory availability and tin mating contact finish. Select this part if your application does not require gold plating and cost optimization is a priority. Tin finish provides adequate corrosion resistance for standard indoor and controlled environment applications.

Q: Are the contact materials identical across all parts?

A: Yes. All parts use Phosphor Bronze contact material with tin post finish. The main difference in contact finish is the mating surface: the main part and three Sullins PBC series parts use gold mating finish, while PEC16DAAN uses tin mating finish.
