Engineering Selection Recommendations
Direct Amphenol ICC Replacement (77313-102-08LF)
The 77313-102-08LF is the active production equivalent from the original manufacturer. It maintains identical mechanical and electrical specifications to the obsolete 77313-102-08 while offering RoHS compliance, active product status, and extended operating temperature range (-65°C to 130°C). This part is the preferred choice for direct substitution in existing designs.
3M 2300 Series (2308-6121-TG, 2308-6121-TP)
The 3M 2300 series headers provide functionally equivalent 8-position, 2-row connectors with active product status. Both variants feature glass-filled thermoplastic insulation and 3A current rating. The 2308-6121-TG offers gold mating contact finish, while 2308-6121-TP provides tin-lead finish. Operating temperature range is -55°C to 105°C. These parts are suitable for applications not requiring extended low-temperature performance.
TE Connectivity AMPMODU Mod II (5-146260-4)
The TE Connectivity 5-146260-4 is an active, RoHS-compliant alternative featuring liquid crystal polymer (LCP) insulation and gold mating contacts. The shorter contact post length (0.090") and reduced insulation height (0.090") may require PCB design verification for compatibility. Operating temperature range extends to -65°C to 105°C with 3A current rating.
Sullins Connector Solutions PBC04 Series (PBC04DAAN through PBC04DAFN)
The Sullins PBC04 series provides multiple variants with varying contact post lengths (0.120" to 0.620"), enabling selection based on specific PCB stack-up requirements. All variants feature ROHS3 compliance, phosphor bronze contacts with gold mating finish, and polybutylene terephthalate (PBT) insulation. Operating temperature range is -65°C to 125°C with 3A current rating. These parts offer the widest selection for applications requiring specific post length specifications.
Frequently Asked Questions (FAQ)
Q: Can the 77313-102-08LF directly replace the obsolete 77313-102-08?
A: Yes. The 77313-102-08LF maintains identical mating pitch (0.100"), position count (8), row configuration (2 rows), contact geometry, and push-pull fastening. The primary differences are active product status, RoHS compliance, and extended operating temperature range (-65°C to 130°C versus unspecified for the original).
Q: What is the significance of contact post length variations in the Sullins PBC04 series?
A: Contact post length determines the depth of solder connection into the PCB. The PBC04DAAN (0.120" post) matches standard through-hole depth, while longer variants (PBC04DABN through PBC04DAFN) accommodate thicker PCB assemblies or specific board stack-up configurations. Selection depends on PCB thickness and solder joint requirements.
Q: Are the 3M 2300 series parts suitable for low-temperature applications?
A: The 3M 2300 series operates from -55°C to 105°C, which is narrower than alternatives. For applications requiring operation below -55°C, the Amphenol ICC 77313-102-08LF (-65°C to 130°C), TE Connectivity 5-146260-4 (-65°C to 105°C), or Sullins PBC04 series (-65°C to 125°C) are more appropriate.
Q: What is the difference between gold and tin-lead contact finishes?
A: Gold mating contacts (77313-102-08LF, 2308-6121-TG, 5-146260-4, all Sullins variants) provide superior corrosion resistance and lower contact resistance. Tin-lead finish (2308-6121-TP) is cost-effective but offers reduced corrosion protection. For applications with extended shelf life or harsh environments, gold-finished contacts are preferred.
Q: Can I use parts with different insulation materials interchangeably?
A: Yes, for standard through-hole PCB applications. The thermoplastic, glass-filled thermoplastic, liquid crystal polymer, and polybutylene terephthalate insulation materials all meet UL94 V-0 flammability requirements and maintain equivalent electrical performance at the specified pitch and position count. Material selection affects mechanical durability and temperature performance but not mating compatibility.
Q: Which substitute part offers the best compliance for new designs?
A: The Amphenol ICC 77313-102-08LF and all Sullins PBC04 variants offer the highest compliance status (RoHS Compliant or ROHS3 Compliant). For designs requiring REACH compliance, the Amphenol ICC 77313-102-08LF (REACH Affected) and Sullins variants (REACH Unaffected) are available. Compliance requirements should be verified against specific design standards.
Q: Is the TE Connectivity 5-146260-4 compatible with standard PCB designs for the 77313-102-08?
A: The 5-146260-4 maintains mating pitch and position count but features reduced insulation height (0.090" versus 0.100") and shorter contact post (0.090" versus 0.135"). PCB footprint compatibility requires verification, particularly for board thickness and solder joint depth. Mechanical fit should be confirmed before design implementation.
