Amphenol ICC 68657-404HLF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68657-404HLF is a rectangular connector header in the BERGSTIK® II series, designed for through-hole board-to-board applications. This 4-position, 0.100" (2.54mm) pitch connector features male pins with tin-plated phosphor bronze contacts and is rated for 5A at 110V. The part maintains Active product status with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified to provide alternative sourcing options where design specifications permit variation in contact type, contact finish, insulation material, or packaging format while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters:

• Connector Position Count: Must equal 4 positions
• Pitch Specification: Must equal 0.100" (2.54mm)
• Mounting Configuration: Must be Through Hole
• Termination Method: Must be Solder
• Row Configuration: Must be single row
• Flammability Rating: Must meet or exceed UL94 V-0
• RoHS Compliance: Must be RoHS3 or RoHS Compliant
• Moisture Sensitivity: Must be MSL 1 (Unlimited)

Substitute parts are grouped into two categories based on contact type variation:

Group 1 - Solder Cup Contact Type (380-10-104-00-001000): Maintains header connector architecture with alternative contact termination geometry.

Group 2 - Spring Piston Contact Type (821-22-004-10-002101, 821-22-004-10-003101, 821-22-004-10-004101): Provides piston-based contact mechanism with spring retention, differing in packaging format only.

Group 3 - Male Pin Header with Extended Mating Length (MTLW-104-05-G-S-170, MTLW-104-05-G-S-185): Maintains male pin header architecture with variation in contact mating length and insulation material (LCP vs. standard).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status with RoHS3 compliance or RoHS compliance certification, ensuring regulatory alignment with the original 68657-404HLF specification.

For direct form-fit-function replacement with identical contact geometry: Select MTLW-104-05-G-S-170 or MTLW-104-05-G-S-185 from Samtec. These maintain male pin header architecture with phosphor bronze contacts and UL94 V-0 flammability rating. Contact mating length variation (0.170" vs. 0.185") accommodates different PCB thickness requirements within the same connector family.

For alternative contact termination with solder cup geometry: Select 380-10-104-00-001000 from Mill-Max. This maintains header connector form factor with gold-plated solder cup contacts, suitable for applications requiring alternative termination geometry.

For spring piston contact mechanism: Select from Mill-Max 821 series (821-22-004-10-002101, 821-22-004-10-003101, or 821-22-004-10-004101). These provide spring-retained piston contacts with gold plating. Selection among these three variants is determined by packaging requirement (Bulk or Tube format).

Frequently Asked Questions (FAQ)

Q: Can the 68657-404HLF be directly replaced with the MTLW-104-05-G-S-170 or MTLW-104-05-G-S-185?

A: These Samtec parts maintain compatible 4-position, 0.100" pitch through-hole solder termination with male pin contacts. Primary differences are contact mating length (0.170" or 0.185" vs. 0.120" on the original), insulation material (LCP vs. standard), and contact finish (gold vs. tin). Compatibility depends on PCB design accommodation for the extended mating length and acceptance of gold-plated contacts.

Q: What is the functional difference between the Mill-Max 380 series and 821 series substitutes?

A: The 380-10-104-00-001000 maintains header connector architecture with solder cup contact termination. The 821 series (piston variants) uses spring-retained piston contacts instead of male pins. Both achieve 4-position, 0.100" pitch through-hole solder termination but with different contact engagement mechanisms.

Q: Are there packaging differences among the Mill-Max 821 series substitutes?

A: The three 821 series parts (821-22-004-10-002101, 821-22-004-10-003101, 821-22-004-10-004101) are electrically and mechanically identical. Differences are limited to packaging format: two are supplied in Bulk packaging, one in Tube packaging. Selection is based on procurement and handling requirements only.

Q: Does contact finish (tin vs. gold) affect electrical performance?

A: Contact finish affects corrosion resistance and long-term reliability in specific environmental conditions. Tin-plated contacts (68657-404HLF) provide standard performance. Gold-plated contacts (all substitutes) offer enhanced corrosion resistance. Both finishes are suitable for standard industrial applications at the specified 5A current rating.

Q: What is the significance of the contact mating length difference in the Samtec MTLW parts?

A: Contact mating length determines how far the male pin extends into the mating connector. The 0.170" and 0.185" variants accommodate different PCB thicknesses or mating connector depths. Selection depends on the specific mating connector or socket specification in the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry ROHS3 Compliant or RoHS Compliant certification, maintaining regulatory compliance with the original 68657-404HLF specification.
