Amphenol ICC 61641-602 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 61641-602 is an active rectangular connector header designed for through-hole board-to-board or cable applications. This 44-position, 2-row connector with 0.079" (2.00mm) pitch operates at 2A per contact and 200V, featuring gold-plated mating contacts and tin-lead plated posts. The connector is UL94 V-0 rated and RoHS non-compliant. Substitute parts are identified to provide alternative sourcing options where equivalent electrical and mechanical parameters are maintained.

Substitute Part Grouping Explanation

Substitute parts for the 61641-602 are identified based on strict equivalence of core electrical and mechanical parameters. The primary substitution criteria are:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 44
• Number of rows: 2
• Pitch - mating: 0.079" (2.00mm)
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Shrouding: Unshrouded
• Style: Board to Board or Cable

The Samtec Inc. TMM-122-03-L-D meets all core substitution criteria and maintains functional compatibility with the 61641-602 in applications requiring these specific connector parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 61641-602 and TMM-122-03-L-D are active products suitable for through-hole board-to-board and cable connector applications with identical pitch and position configurations.

The 61641-602 is RoHS non-compliant and carries a UL94 V-0 flammability rating. The TMM-122-03-L-D is ROHS3 compliant and provides higher current capacity (3.2A per contact versus 2A) with an extended operating temperature range of -55°C to 125°C. Both connectors maintain MSL 1 (Unlimited) moisture sensitivity classification.

Selection between these parts should be based on regulatory compliance requirements, current capacity needs, and operating temperature specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Are the 61641-602 and TMM-122-03-L-D mechanically interchangeable?

A: Both connectors share identical pitch (0.079" / 2.00mm), position count (44), row configuration (2 rows), and mounting type (through-hole solder). Minor differences exist in contact post length (0.098" versus 0.106") and overall contact length (0.315" versus 0.323"), which may require PCB layout verification for specific applications.

Q: What is the primary difference in compliance between these parts?

A: The 61641-602 is RoHS non-compliant, while the TMM-122-03-L-D is ROHS3 compliant. Applications subject to RoHS regulations should use the TMM-122-03-L-D.

Q: Do these connectors have different current ratings?

A: Yes. The 61641-602 is rated at 2A (AC/DC), while the TMM-122-03-L-D is rated at 3.2A per contact. Applications requiring higher current capacity should use the TMM-122-03-L-D.

Q: What are the contact material differences?

A: The 61641-602 uses Copper Alloy contacts, while the TMM-122-03-L-D uses Phosphor Bronze. Both materials are suitable for solder termination and push-pull fastening applications.

Q: Does the insulation material difference affect compatibility?

A: The 61641-602 uses Thermoplastic insulation, while the TMM-122-03-L-D uses Liquid Crystal Polymer (LCP). The TMM-122-03-L-D's LCP insulation provides enhanced thermal and dimensional stability. Both materials are black and suitable for the specified applications.

Q: What operating temperature range should be considered?

A: The 61641-602 does not specify an operating temperature range. The TMM-122-03-L-D operates from -55°C to 125°C. Applications requiring defined temperature specifications should use the TMM-122-03-L-D.
