Amphenol ICC 76383-420 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76383-420 is a right-angle header connector with 40 positions at 0.100" (2.54mm) pitch, designed for through-hole board-to-cable/wire applications. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across connector type, pitch, position count, mounting orientation, and electrical ratings to ensure direct interchangeability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76383-420 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type (Header vs. Receptacle)
• Contact type (Male Pin vs. Female Socket)
• Number of positions (40)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A minimum)
• Operating temperature range (-40°C ~ 125°C)

Identified Substitutes:

1. 76383-420LF - Direct form, fit, and function equivalent. Maintains identical connector type (Header), contact type (Male Pin), position count, pitch, mounting orientation, and electrical ratings. Primary difference is RoHS compliance status (Active vs. Obsolete) and contact finish specification (Tin vs. Tin-Lead).

2. 87606-320CLF - Functional alternative with critical differences. Receptacle connector (Female Socket) rather than Header (Male Pin), indicating use in complementary mating applications. Maintains 40 positions, 2 rows, 0.100" pitch, and through-hole solder termination. Board-to-board style differs from board-to-cable/wire application. Not a direct pin-for-pin replacement but compatible within Dubox™ series ecosystem.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-for-Pin Compatibility):

Select 76383-420LF when maintaining the original board-to-cable/wire header configuration. This part provides identical form factor, contact arrangement, and electrical performance. The transition from RoHS non-compliant to RoHS Compliant status aligns with current regulatory requirements. Contact finish changes from Tin-Lead to Tin, with adjusted thickness specifications (78.7µin vs. 150.0µin), maintain electrical and mechanical performance within Dubox™ series tolerances. Active product status ensures ongoing availability and supply chain stability.

For Complementary Mating Applications:

Select 87606-320CLF when the design requires a receptacle connector to mate with the 76383-420 or 76383-420LF header. This part maintains the 40-position, 2-row, 0.100" pitch architecture within the Dubox™ series. The board-to-board configuration and push-pull fastening differ from the original header specification, requiring circuit board layout and mechanical mounting adjustments. RoHS Compliant status and Active product status support modern manufacturing and regulatory compliance.

Compliance Considerations:

Both substitute parts are RoHS Compliant and carry Active product status, addressing obsolescence concerns associated with the original 76383-420. Material flammability ratings (UL94 V-0) remain consistent across all three parts, supporting applications with equivalent thermal and fire safety requirements.

Frequently Asked Questions (FAQ)

Q: Can 76383-420LF be used as a direct replacement for 76383-420?

A: Yes. The 76383-420LF maintains identical connector type (Header), contact type (Male Pin), position count (40), row configuration (2 rows), pitch (0.100"), mounting type (Through Hole, Right Angle), and current rating (3A). The primary differences are product status (Active vs. Obsolete), RoHS compliance, and contact finish specifications, which do not affect functional interchangeability in existing designs.

Q: What is the difference between 76383-420LF and 87606-320CLF?

A: The 76383-420LF is a header connector (Male Pin) for board-to-cable/wire applications, while 87606-320CLF is a receptacle connector (Female Socket) for board-to-board applications. Both maintain 40 positions, 2 rows, and 0.100" pitch within the Dubox™ series. These parts are complementary mating connectors, not direct replacements. Selection depends on the application requirement: header for cable connections or receptacle for board-to-board connections.

Q: Are there packaging differences between these parts?

A: The 76383-420 (Obsolete) has unspecified packaging. Both 76383-420LF and 87606-320CLF are supplied in Tube packaging, supporting automated assembly processes and standard component handling.

Q: Do all three parts support the same operating temperature range?

A: The 76383-420 and 76383-420LF both specify -40°C ~ 125°C operating temperature. The 87606-320CLF does not provide an explicit operating temperature specification in the available data. Verify operating temperature requirements with the manufacturer for applications requiring temperature range confirmation.

Q: What are the contact finish differences, and do they affect performance?

A: The 76383-420 uses Tin-Lead finish (150.0µin mating, 150.0µin post). The 76383-420LF uses Tin finish (78.7µin mating, 78.7µin post). The 87606-320CLF uses Gold finish on mating contacts (30.0µin) and Tin on post contacts (78.7µin). These finishes support equivalent electrical conductivity and contact reliability within their respective specifications. Selection should align with PCB surface finish compatibility and soldering process requirements.

Q: Are all parts RoHS compliant?

A: The 76383-420 is RoHS non-compliant. Both 76383-420LF and 87606-320CLF are RoHS Compliant. For applications subject to RoHS regulations, select 76383-420LF or 87606-320CLF.

Q: What is the current rating for each part?

A: The 76383-420 and 76383-420LF both specify 3A current rating. The 87606-320CLF does not provide an explicit current rating specification. Verify current requirements with the manufacturer for applications requiring current rating confirmation.
