Substitute Part Grouping Explanation

Substitution of the 77313-824-14 is determined by strict equivalence in the following critical parameters:

Number of Positions: 14
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole

Substitute parts are grouped into two categories:

Direct Amphenol ICC Equivalents: Parts that maintain identical electrical and mechanical specifications within the same manufacturer series, with the primary distinction being product status (active vs. obsolete) and RoHS compliance.

Cross-Manufacturer Equivalents: Parts from TE Connectivity, 3M, and Samtec that meet the core dimensional and electrical requirements. These parts may exhibit variations in contact length, insulation material, contact finish specifications, and operating temperature ranges, but maintain functional compatibility based on the 14-position, 2-row, 2.54mm pitch configuration.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 77313-824-14LF

The 77313-824-14LF is the direct active equivalent within the same manufacturer series. It maintains identical electrical and mechanical specifications to the obsolete 77313-824-14, with the distinction of RoHS compliance and active product status. This part is recommended for direct replacement in new designs and production continuity. The LF suffix indicates lead-free post finish (tin instead of tin-lead), which aligns with modern manufacturing standards.

Secondary Recommendations for RoHS-Compliant Designs:

TE Connectivity 5-146252-7 or 5-146253-7: AMPMODU Mod II series headers provide ROHS3 or RoHS compliance with identical 14-position, 2-row, 2.54mm pitch configuration. These parts feature liquid crystal polymer (LCP) insulation and copper alloy contacts with 3A current rating per contact. Operating temperature range extends to -65°C ~ 105°C.
TE Connectivity 826632-7: AMPMODU Mod II variant with higher current rating (5A per contact) and brass contacts. Insulation material is polybutylene terephthalate (PBT) with green color. ROHS3 compliant.

Alternative Manufacturers:

3M 2314-6221-TB: 2300 series header with identical 14-position configuration. RoHS non-compliant but offers glass-filled thermoplastic insulation and tin-lead post finish matching the original part. Operating temperature -55°C ~ 105°C.
3M 929665-01-07-I: 929 series header with RoHS compliance. Operates at -40°C ~ 105°C with 2.5A current rating per contact. Gold-plated post finish.
Samtec BBD-107-G-A or BBD-107-T-B: BBD series headers with ROHS3 compliance. These parts feature circular contact geometry and extended operating temperature range (-55°C ~ 125°C). Contact finish options include gold (BBD-107-G-A) or tin (BBD-107-T-B) on mating surfaces with nickel post finish.

Compliance Considerations:

For applications requiring RoHS compliance, select from: 77313-824-14LF, 5-146252-7, 5-146253-7, 826632-7, 929665-01-07-I, BBD-107-G-A, or BBD-107-T-B. The original 77313-824-14 and 3M 2314-6221-TB are RoHS non-compliant and suitable only for legacy or non-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the obsolete 77313-824-14 be directly replaced with 77313-824-14LF?

A: Yes. The 77313-824-14LF is the direct active equivalent with identical electrical and mechanical specifications. The primary differences are product status (active vs. obsolete) and post finish (tin vs. tin-lead). Both maintain the same 14-position, 2-row, 2.54mm pitch configuration and UL94 V-0 flammability rating.

Q: What are the key parameters that determine connector substitutability?

A: The critical parameters are: number of positions (14), number of rows (2), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), connector type (header), contact type (male pin), mounting type (through hole), and termination method (solder). All substitute parts listed maintain these specifications.

Q: Are there dimensional differences between substitute parts?

A: Yes. While all substitute parts maintain the same mating pitch and position count, contact length, overall contact length, and insulation height vary across manufacturers. For example, TE Connectivity AMPMODU parts have 0.318" mating contact length versus 0.266" for the original Amphenol part. Samtec BBD series headers feature circular contacts with different overall dimensions. These variations do not affect functional compatibility with standard 2.54mm pitch receptacles but may impact PCB layout and mechanical clearance.

Q: Which substitute parts are RoHS compliant?

A: RoHS-compliant options include: 77313-824-14LF (RoHS Compliant), 5-146252-7 (ROHS3 Compliant), 5-146253-7 (RoHS Compliant), 826632-7 (ROHS3 Compliant), 929665-01-07-I (RoHS Compliant), BBD-107-G-A (ROHS3 Compliant), and BBD-107-T-B (ROHS3 Compliant). The original 77313-824-14 and 3M 2314-6221-TB are RoHS non-compliant.

Q: What is the difference between tin and tin-lead post finishes?

A: The original 77313-824-14 features tin-lead post finish (150.0µin / 3.81µm thickness). The 77313-824-14LF uses tin post finish (78.7µin / 2.00µm thickness). Tin-lead finishes are associated with legacy manufacturing processes and are restricted under RoHS regulations. Tin finishes are RoHS-compliant alternatives. Both provide adequate solder joint reliability when properly soldered.

Q: Do all substitute parts have the same current rating?

A: No. Current ratings vary: the original part does not specify a rating, 77313-824-14LF and TE Connectivity parts (5-146252-7, 5-146253-7) are rated 3A per contact, 826632-7 is rated 5A per contact, 929665-01-07-I is rated 2.5A per contact, and Samtec BBD series parts do not specify a rating. Select based on application current requirements.

Q: What is the operating temperature range for each substitute?

A: Operating temperature ranges vary: 77313-824-14LF operates -65°C ~ 130°C, 3M 2314-6221-TB operates -55°C ~ 105°C, TE Connectivity 5-146252-7 and 5-146253-7 operate -65°C ~ 105°C, 826632-7 operates -65°C ~ 105°C, 929665-01-07-I operates -40°C ~ 105°C, and Samtec BBD series parts operate -55°C ~ 125°C. Select based on application thermal requirements.

Q: Are Samtec BBD-107 headers compatible with standard 2.54mm pitch receptacles?

A: The BBD-107 series maintains 0.100" (2.54mm) mating pitch and 2-row configuration, ensuring mechanical compatibility with standard 2.54mm pitch receptacles. However, the circular contact geometry differs from the square contacts of other listed parts. Verify receptacle contact geometry compatibility before substitution.

Q: What packaging options are available for these substitute parts?

A: Packaging varies by part number. 77313-824-14LF is supplied in bulk, 95278-801A04LF in tape & reel, 3M parts in bulk or tube, TE Connectivity parts in bulk, and Samtec parts in tube. Select packaging based on production volume and assembly process requirements.
