Engineering Selection Recommendations

Primary Recommendation: 77313-122-10LF

The 77313-122-10LF is the direct active equivalent from Amphenol ICC. It maintains identical electrical and mechanical specifications to the obsolete 77313-122-10 while offering RoHS compliance and active product status. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendations for Active Designs:

Preci-Dip 450-10-210-00-018101 and 451-80-210-00-003101 are ROHS3 compliant alternatives with extended operating temperature range (-55°C to 125°C) and higher current ratings (3A). These parts are suitable for applications requiring enhanced thermal performance and regulatory compliance.

TE Connectivity 826632-5 offers ROHS3 compliance with increased current capacity (5A per contact) and is available in bulk packaging. This part is appropriate for high-volume production requiring improved electrical performance.

Samtec MTLW-105-08-G-D-318 provides ROHS3 compliance with the highest current rating (5.2A per contact) and extended mating contact length (0.318"). This variant is suitable for applications with demanding electrical requirements and space constraints.

Samtec BBD-105-G-A and BBD-105-T-A offer ROHS3 compliance with alternative contact finishes (gold or tin). These parts are suitable for applications where specific contact finish requirements differ from the original specification.

3M 2310-6221-TB and 2310-6221-TP maintain active product status with 3A current rating and UL94 V-0 flammability rating. These parts are suitable for applications where 3M component qualification is required.

Frequently Asked Questions (FAQ)

Q: Can the 77313-122-10LF be used as a direct replacement for the obsolete 77313-122-10?

A: Yes. The 77313-122-10LF maintains identical pitch (0.100"), position count (10), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination (solder). The primary difference is active product status and RoHS compliance. Mechanical and electrical compatibility is confirmed.

Q: What are the key differences between the Amphenol ICC 77313-122-10LF and the Preci-Dip 450-10-210-00-018101?

A: Both parts share identical pitch, position count, and row spacing. Differences include contact material (phosphor bronze vs. brass), contact finish (gold vs. gold), insulation material composition, and operating temperature range. The Preci-Dip part offers extended temperature range (-55°C to 125°C) and ROHS3 compliance. Mechanical compatibility is confirmed for board-to-board applications.

Q: Are there packaging differences between substitute parts?

A: Yes. The 77313-122-10LF is supplied in bulk packaging. The Samtec BBD-105-G-A and BBD-105-T-A are supplied in tube packaging. Preci-Dip 450-10-210-00-018101 and 451-80-210-00-003101 are supplied in bulk. TE Connectivity 826632-5 is supplied in bulk. Packaging does not affect electrical or mechanical compatibility.

Q: Which substitute part offers the highest current rating?

A: The Samtec MTLW-105-08-G-D-318 offers the highest current rating at 5.2A per contact, followed by the TE Connectivity 826632-5 at 5A per contact. The original 77313-122-10 does not specify a current rating.

Q: What is the difference between the Samtec BBD-105-G-A and BBD-105-T-A?

A: Both parts are identical except for mating contact finish. The BBD-105-G-A features gold mating contact finish, while the BBD-105-T-A features tin mating contact finish. Both maintain identical pitch, position count, and row configuration. Selection depends on application-specific contact finish requirements.

Q: Are all substitute parts RoHS compliant?

A: No. The 3M 2310-6221-TB and 2310-6221-TP are RoHS non-compliant. The Amphenol ICC 77313-122-10LF, Preci-Dip 450-10-210-00-018101, Preci-Dip 451-80-210-00-003101, TE Connectivity 826632-5, Samtec BBD-105-G-A, Samtec BBD-105-T-A, and Samtec MTLW-105-08-G-D-318 are all ROHS3 compliant or RoHS compliant.

Q: Can the Samtec EW-05-09-F-D-200 be used as a substitute?

A: The Samtec EW-05-09-F-D-200 is a Flex Stack variant with integrated spacer functionality. While it maintains the 0.100" pitch and 10-position configuration, it features extended overall pin length (0.730") and integrated stack height (0.200"). This part is suitable only for applications requiring spacer functionality and is not a direct mechanical replacement for standard header applications.

Q: What is the REACH compliance status of substitute parts?

A: The Amphenol ICC 77313-122-10LF, Preci-Dip 450-10-210-00-018101, Preci-Dip 451-80-210-00-003101, and Samtec BBD-105-T-A are REACH Unaffected. The 3M 2310-6221-TB, 3M 2310-6221-TP, Samtec BBD-105-G-A, and Samtec MTLW-105-08-G-D-318 are REACH Unaffected. The TE Connectivity 826632-5 is REACH Unaffected.
