Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: connector type (header, breakaway), contact type (male pin), number of positions (20), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole), termination method (solder), fastening type (push-pull), and material flammability rating (UL94 V-0).

Substitute parts are grouped into two categories based on contact geometry and material composition:

Category A - Square Contact Geometry: Parts maintaining square contact shape with phosphor bronze or copper alloy materials. These include 1-826632-0 (TE Connectivity), 2320-6221-TG (3M), 6-146250-0 (TE Connectivity), PBC10DFAN, PBC10DFBN, PEC10DFAN, and PEC10DFCN (Sullins Connector Solutions). These parts preserve the original contact profile while offering variations in contact finish, insulation material, and thermal ratings.

Category B - Circular Contact Geometry: Parts featuring circular contact shape with phosphor bronze material. These include 87215-7 (TE Connectivity), BBD-110-G-A, and BBD-110-T-A (Samtec Inc.). These parts maintain electrical compatibility through equivalent current ratings and contact materials but differ in contact geometry and insulation construction.

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select from 1-826632-0, 6-146250-0, 87215-7, BBD-110-G-A, BBD-110-T-A, PBC10DFAN, PBC10DFBN, PEC10DFAN, or PEC10DFCN. These parts carry ROHS3 Compliant certification. The 77313-122-20LF maintains RoHS Compliant status; 2320-6221-TG is RoHS non-compliant and should not be selected for new designs requiring RoHS3 compliance.

For Extended Thermal Operating Range: Parts rated to -65°C ~ 125°C include PBC10DFAN, PBC10DFBN, PEC10DFAN, and PEC10DFCN (Sullins Connector Solutions). The 77313-122-20LF supports -65°C ~ 130°C, providing the highest upper temperature limit. TE Connectivity parts (1-826632-0, 6-146250-0, 87215-7) and 2320-6221-TG are limited to -65°C ~ 105°C or -55°C ~ 105°C. Samtec BBD series parts support -55°C ~ 125°C.

For Packaging Format: The 77313-122-20LF is supplied in Bulk packaging. Equivalent bulk-packaged substitutes include all TE Connectivity and Sullins parts. Samtec BBD-110-G-A and BBD-110-T-A are supplied in Tube packaging and should be selected only when tube packaging is acceptable for supply chain or handling requirements.

For Contact Geometry Compatibility: Square contact geometry is maintained by 1-826632-0, 2320-6221-TG, 6-146250-0, PBC10DFAN, PBC10DFBN, PEC10DFAN, and PEC10DFCN. Circular contact geometry is used in 87215-7, BBD-110-G-A, and BBD-110-T-A. Contact geometry selection depends on mating connector specifications and PCB layout constraints.

For Current Rating Considerations: The 77313-122-20LF is rated at 3A per contact. The 1-826632-0 (TE Connectivity) provides 5A current rating, offering higher current capacity for applications requiring increased power delivery. All other substitutes maintain 3A rating or do not specify current rating.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 77313-122-20LF with any of these parts directly on my PCB?

A: Direct substitution depends on contact geometry and mating connector specifications. Parts with square contact geometry (1-826632-0, 2320-6221-TG, 6-146250-0, PBC10DFAN, PBC10DFBN, PEC10DFAN, PEC10DFCN) are mechanically compatible with square-contact receptacles. Parts with circular contact geometry (87215-7, BBD-110-G-A, BBD-110-T-A) require circular-contact mating connectors. Verify mating connector specifications before selection.

Q: What is the difference between the Sullins parts (PBC10DFAN, PBC10DFBN, PEC10DFAN, PEC10DFCN)?

A: Sullins parts differ in contact post length and contact finish. PBC10DFAN features 0.120" post length with gold mating finish. PBC10DFBN features 0.220" post length with gold mating finish. PEC10DFAN features 0.120" post length with tin mating finish. PEC10DFCN features 0.320" post length with tin mating finish. Selection depends on PCB thickness and solder joint requirements.

Q: Is the 2320-6221-TG (3M) suitable for new designs?

A: The 2320-6221-TG carries RoHS non-compliant status and is not recommended for new designs requiring RoHS3 compliance. It is suitable only for legacy system maintenance or applications where RoHS compliance is not mandated. For new designs, select from ROHS3 Compliant alternatives.

Q: What is the thermal operating range difference between the 77313-122-20LF and substitute parts?

A: The 77313-122-20LF supports -65°C ~ 130°C. TE Connectivity parts (1-826632-0, 6-146250-0, 87215-7) support -65°C ~ 105°C. The 2320-6221-TG supports -55°C ~ 105°C. Sullins parts support -65°C ~ 125°C. Samtec BBD series supports -55°C ~ 125°C. For applications exceeding 105°C, select the 77313-122-20LF, Sullins parts, or Samtec BBD series.

Q: Does packaging format affect electrical performance?

A: No. Bulk and Tube packaging formats do not affect electrical performance or connector specifications. Packaging selection is determined by supply chain requirements, handling procedures, and inventory management practices.

Q: What contact material is used in the BBD-110-G-A and BBD-110-T-A?

A: Contact material is not specified in the technical data for BBD-110-G-A and BBD-110-T-A. Contact the manufacturer (Samtec Inc.) for detailed material composition if this specification is critical for your application.

Q: Can I use the 1-826632-0 (5A rating) in place of the 77313-122-20LF (3A rating)?

A: Yes, the 1-826632-0 with 5A current rating can be used as a direct substitute for the 77313-122-20LF in applications requiring 3A or less per contact. The higher current rating provides additional design margin. However, verify that the mating connector and PCB trace design support the higher current capacity if future upgrades are planned.
