Amphenol ICC 86453-026LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 86453-026LF is a through-hole, right-angle rectangular connector header with 26 positions arranged in 2 rows at 0.079" (2.00mm) pitch. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity. The part features gold-plated mating contacts, tin-plated posts, and phosphor bronze contact material suitable for board-to-board or cable applications with push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 86453-026LF is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, 26 positions in 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Materials & Finish: Phosphor bronze with gold mating surface and tin post finish
• Electrical Performance: Minimum 2A current rating and 200V voltage rating
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification

Substitute parts must maintain these core specifications to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Pitch 0.079" / 2.00mm)

The Molex 0877602617, Harwin M22-2541305, and Samtec TMM-113-01-F-D-RA maintain the critical 0.079" (2.00mm) pitch specification required for direct mechanical and electrical compatibility with existing PCB layouts designed for the 86453-026LF. All three are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The Molex 0877602617 (Milli-Grid 87760 series) provides the closest electrical and mechanical match with identical pitch, row spacing, and contact configuration. This part is suitable for applications requiring direct pin-for-pin replacement.

The Harwin M22-2541305 (M22 series) offers identical pitch and row spacing with cuttable header functionality, providing design flexibility for applications requiring custom position counts. Operating temperature range matches the original specification (-40°C ~ 105°C).

The Samtec TMM-113-01-F-D-RA (TMM series) maintains the 0.079" (2.00mm) pitch with extended operating temperature range (-55°C ~ 125°C) and higher current rating (3.2A per contact), suitable for applications requiring enhanced thermal performance.

Alternative Substitute (Pitch 0.100" / 2.54mm)

The Samtec HMTSW-113-07-G-D-130-RA (Flex Stack, HMTSW series) operates at 0.100" (2.54mm) pitch and row spacing, which differs from the original specification. This part is not mechanically compatible with existing PCB layouts designed for 0.079" (2.00mm) pitch and should only be considered for new designs or applications where PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the Samtec HMTSW-113-07-G-D-130-RA be used as a direct replacement for the 86453-026LF?

A: No. The HMTSW-113-07-G-D-130-RA operates at 0.100" (2.54mm) pitch and row spacing, while the 86453-026LF requires 0.079" (2.00mm) pitch. Direct substitution would require PCB redesign and is not mechanically compatible with existing mating connectors.

Q: Which substitute part offers the best thermal performance?

A: Both the Samtec TMM-113-01-F-D-RA and HMTSW-113-07-G-D-130-RA support extended operating temperature ranges (-55°C ~ 125°C) compared to the original specification (-40°C ~ 105°C). For applications requiring this extended range with 0.079" (2.00mm) pitch compatibility, the TMM-113-01-F-D-RA is the appropriate selection.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0877602617, Samtec HMTSW-113-07-G-D-130-RA, Harwin M22-2541305, and Samtec TMM-113-01-F-D-RA are all ROHS3 compliant. The original 86453-026LF RoHS status is not specified in the provided data.

Q: What is the difference between the Molex and Harwin substitutes?

A: Both maintain 0.079" (2.00mm) pitch and row spacing. The Harwin M22-2541305 features cuttable header functionality, allowing custom position configurations. The Molex 0877602617 is a fixed 26-position header. Selection depends on whether design flexibility for position count is required.

Q: Do all substitute parts support the same current and voltage ratings?

A: The original 86453-026LF specifies 2A current and 200V voltage ratings. The Molex 0877602617 and Samtec HMTSW-113-07-G-D-130-RA do not specify voltage ratings in the provided data. The Samtec TMM-113-01-F-D-RA supports 3.2A per contact, exceeding the original specification. Verify electrical requirements for your specific application before selection.
