Engineering Selection Recommendations

Samtec Tiger Claw™ BCS Series (Preferred for Direct Replacement)

The Samtec BCS series connectors (BCS-108-F-S-DE, BCS-108-F-S-DE-BE, BCS-108-F-S-TE, BCS-108-FM-S-DE, BCS-108-FM-S-DE-BE, BCS-108-FM-S-TE) provide the closest functional equivalence to the 68684-308. These parts maintain receptacle connector configuration with square contact geometry and phosphor bronze contact material, matching the original design. All variants are active products with ROHS3 compliance and UL94 V-0 flammability rating. The BCS series offers enhanced electrical performance with 4.6A per contact current rating and 475VAC voltage rating. Operating temperature range of -55°C ~ 125°C exceeds typical industrial requirements.

Preci-Dip 316 and 801 Series (Alternative Socket Connectors)

The Preci-Dip 316 series (316-83-108-41-003101, 316-83-108-41-018101, 316-87-108-41-003101) and 801 series (801-83-008-10-003101) provide functional substitution with socket connector configuration. These parts maintain 8-position, 0.100" pitch configuration with gold-plated mating contacts and through-hole solder termination. All are active products with ROHS3 compliance and UL94 V-0 rating. Socket geometry differs from the original receptacle design, requiring compatibility assessment with existing mating plugs. Current rating of 3A per contact is lower than the BCS series. Operating temperature range of -55°C ~ 125°C is suitable for industrial applications.

Selection Criteria:

For direct mechanical and electrical replacement, select from the Samtec BCS series. For applications where socket-style connectors are acceptable and cost optimization is prioritized, Preci-Dip 316 or 801 series connectors are viable alternatives. All substitute parts meet RoHS compliance and UL94 V-0 flammability requirements. Verify mating plug compatibility before final selection, particularly when transitioning from receptacle to socket connector types.

Frequently Asked Questions (FAQ)

Q: Can Preci-Dip socket connectors replace the Amphenol ICC 68684-308 receptacle directly?

A: Preci-Dip 316 and 801 series connectors are socket-style connectors, while the 68684-308 is a receptacle. Socket and receptacle connectors have different contact geometries and mating interfaces. Direct mechanical substitution is not possible without adapter solutions. Compatibility depends on the mating plug design in your application.

Q: What is the difference between BCS-108-F-S-DE and BCS-108-FM-S-DE?

A: Both variants are receptacle connectors from Samtec's Tiger Claw™ BCS series with identical electrical and mechanical specifications. The designation difference reflects internal design variations. Both maintain 8-position, 0.100" pitch configuration with gold-plated mating contacts and 4.6A per contact current rating. Selection between variants should be based on packaging availability and inventory requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. The original 68684-308 is RoHS Compliant. All alternatives meet current RoHS requirements for new production and maintenance applications.

Q: What is the difference between BCS-108-F-S-TE and BCS-108-F-S-DE?

A: Both are Samtec BCS series receptacle connectors with identical electrical specifications. The designation suffix indicates entry configuration: TE denotes top entry, while DE denotes bottom or top entry. Both maintain 8-position, 0.100" pitch configuration with gold-plated mating contacts. Selection depends on PCB layout requirements and connector orientation in your application.

Q: Do the Preci-Dip connectors have the same contact material as the original?

A: No. The 68684-308 uses phosphor bronze contacts, while Preci-Dip 316 and 801 series connectors use beryllium copper contacts. Both materials provide reliable electrical performance with gold plating. Beryllium copper offers different mechanical properties and contact resistance characteristics. Verify compatibility with your application's electrical requirements.

Q: What is the current rating difference between substitute options?

A: Samtec BCS series connectors are rated at 4.6A per contact with 475VAC voltage rating. Preci-Dip 316 and 801 series connectors are rated at 3A per contact with no specified voltage rating. For applications requiring higher current capacity, Samtec BCS series is the appropriate selection.

Q: Are there packaging differences between substitute parts?

A: Yes. Samtec BCS-108-F-S-DE and BCS-108-F-S-TE are supplied in tube packaging. Preci-Dip 316 and 801 series connectors are supplied in bulk packaging. BCS-108-F-S-DE-BE, BCS-108-FM-S-DE, BCS-108-FM-S-DE-BE, and BCS-108-FM-S-TE have unspecified packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the operating temperature range for all substitutes?

A: All substitute parts operate across -55°C ~ 125°C temperature range. The original 68684-308 does not specify an operating temperature range. The substitute parts' temperature range covers typical automotive, industrial, and telecommunications applications.
