Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77313-119-24 is determined by the following critical parameters:

• 24-position, 2-row configuration at 0.100" (2.54mm) pitch
• Through-hole solder termination
• Male pin contact type
• Push-pull fastening mechanism
• Board-to-board or cable style
• Unshrouded design
• UL94 V-0 flammability rating

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalents The 77313-119-24LF is the active production equivalent from the same manufacturer and series, differing only in RoHS compliance status and operating temperature specification.

Category 2: Cross-Manufacturer Alternatives Parts from Molex (0702800371) and Samtec Inc. (BBD-112-T-C, BBD-112-G-C, DW-12-09-F-D-402) meet the core functional requirements of 24-position, 2.54mm pitch, through-hole headers with male pins and push-pull fastening. These alternatives accommodate applications requiring active product status or specific compliance certifications.

Category 3: Non-Equivalent Part The 95242-315ALF is a 30-position receptacle with surface-mount termination and does not meet substitution criteria for the 77313-119-24.

Parameter Comparison

Engineering Selection Recommendations

77313-119-24LF (Amphenol ICC) is the primary substitute for the obsolete 77313-119-24. Both parts share identical mechanical and electrical specifications within the BERGSTIK® series. The 77313-119-24LF carries active product status and RoHS compliance, making it suitable for new designs and applications requiring regulatory compliance.

0702800371 (Molex C-Grid 70280) provides an alternative from an established cross-manufacturer source. This part maintains the 24-position, 2.54mm pitch, through-hole configuration with push-pull fastening. It carries ROHS3 compliance and active product status. Contact geometry and insulation material differ from the original part.

BBD-112-T-C and BBD-112-G-C (Samtec Inc. BBD Series) are functionally equivalent headers with 24 positions at 2.54mm pitch and through-hole solder termination. Both carry ROHS3 compliance and active product status. The BBD-112-G-C features gold mating contact finish, while the BBD-112-T-C uses tin finish. Contact shape is circular rather than square, and overall contact length is longer at 0.835" (21.21mm) compared to 0.724" (18.40mm) for the original part.

DW-12-09-F-D-402 (Samtec Flex Stack, DW Series) is a 24-position header spacer connector at 2.54mm pitch with through-hole solder termination and gold mating contact finish. This part carries ROHS3 compliance and active product status. The spacer design provides a stack height of 0.402" (10.211mm), distinguishing it from standard header configurations.

Frequently Asked Questions (FAQ)

Q: Can the 77313-119-24LF directly replace the obsolete 77313-119-24?

A: Yes. The 77313-119-24LF is the active production equivalent from Amphenol ICC. Both parts share identical pitch (0.100" / 2.54mm), position count (24), row configuration (2 rows), contact type (male pin), mounting method (through-hole solder), and fastening mechanism (push-pull). The primary difference is RoHS compliance status and operating temperature specification on the LF variant.

Q: What are the key differences between Amphenol ICC and cross-manufacturer alternatives?

A: Amphenol ICC parts (77313-119-24 and 77313-119-24LF) use phosphor bronze contacts with square geometry and thermoplastic insulation. Molex 0702800371 employs copper alloy contacts with square geometry and liquid crystal polymer insulation. Samtec BBD series parts use circular contact geometry with polyester insulation. All maintain the 24-position, 2.54mm pitch, through-hole configuration with push-pull fastening.

Q: Are there mechanical compatibility concerns when substituting between manufacturers?

A: Contact geometry differs across manufacturers. The original Amphenol ICC part and Molex 0702800371 use square contacts, while Samtec BBD series employ circular contacts. Overall contact length varies: Amphenol ICC at 0.724" (18.40mm), Molex at 0.670" (17.02mm), and Samtec BBD at 0.835" (21.21mm). These differences may affect mating force, insertion depth, and board layout spacing. Physical verification is necessary for applications with tight mechanical constraints.

Q: Which substitute part offers the best compliance profile?

A: All active substitute parts (77313-119-24LF, 0702800371, BBD-112-T-C, BBD-112-G-C, and DW-12-09-F-D-402) carry ROHS3 compliance. The 77313-119-24LF and 0702800371 maintain UL94 V-0 flammability ratings matching the original part. Samtec parts do not specify flammability ratings in the provided data.

Q: What is the difference between BBD-112-T-C and BBD-112-G-C?

A: Both are 24-position Samtec BBD series headers with identical mechanical specifications. The primary difference is mating contact finish: BBD-112-T-C uses tin finish, while BBD-112-G-C uses gold finish. Both carry ROHS3 compliance and active product status.

Q: Is the DW-12-09-F-D-402 spacer connector suitable as a direct replacement?

A: The DW-12-09-F-D-402 maintains the 24-position, 2.54mm pitch, through-hole solder configuration with push-pull fastening and gold mating contact finish. However, the spacer design introduces a 0.402" (10.211mm) stack height, which differs from standard header configurations. This part is suitable only for applications requiring the spacer functionality.

Q: Why is the 95242-315ALF not listed as a substitute?

A: The 95242-315ALF is a 30-position receptacle with surface-mount termination and female socket contacts. It does not meet the substitution criteria for the 77313-119-24, which requires 24 positions, through-hole mounting, and male pin contacts.
