Amphenol ICC 86453-506 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 86453-506 is a rectangular connector header, right-angle configuration, with 6 positions at 0.079" (2.00mm) pitch. This through-hole component is designed for board-to-board or cable connections with push-pull fastening. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Samtec Inc. offers three active alternatives that maintain electrical and mechanical compatibility while providing improved compliance status and extended temperature operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 86453-506 is based on the following critical parameters that must remain constant:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 6
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header, Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Insulation Color: Black

All three Samtec substitutes (TMM-103-01-G-D-RA, TMM-103-01-S-D-RA, and TMMH-103-01-F-D-RA) maintain these core parameters. The substitutes differ in insulation material composition, contact finish specifications, and post length, which are allowable variations within the rectangular connector category. The primary advantage of these substitutes is their active product status and RoHS3 compliance, compared to the obsolete, non-compliant original part.

Parameter Comparison

Engineering Selection Recommendations

TMM-103-01-G-D-RA is the primary substitute for applications requiring full gold plating on both mating and post contacts. This variant offers RoHS3 compliance, extended operating temperature range (-55°C to 125°C), and higher current capacity (3.2A per contact). The all-gold contact finish provides superior corrosion resistance and is suitable for high-reliability applications.

TMM-103-01-S-D-RA provides an alternative with tin-plated posts while maintaining gold-plated mating contacts. This configuration reduces material cost while preserving mating surface quality. RoHS3 compliance and extended temperature range are maintained. This variant is appropriate for cost-sensitive applications where post finish is less critical.

TMMH-103-01-F-D-RA is designated as a cuttable, low-profile header variant within the TMMH series. This part features the shortest post length (0.092" / 2.34mm) and maintains UL94 V-0 flammability rating matching the original part. The low-profile design is suitable for space-constrained PCB layouts. RoHS3 compliance and extended temperature range apply.

All three substitutes are active products with established supply chains, providing long-term availability compared to the obsolete 86453-506.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TMM series headers directly replace the Amphenol ICC 86453-506 in existing designs?

A: Yes, all three Samtec variants maintain the critical mating parameters: 0.079" (2.00mm) pitch, 6 positions, 2 rows, right-angle through-hole mounting, and push-pull fastening. PCB footprints designed for the 86453-506 are compatible with these substitutes. Minor differences in contact length and insulation height are within acceptable mechanical tolerances for standard board-to-board applications.

Q: What is the difference between the three Samtec substitutes?

A: The primary differences are contact finish specifications and post length. TMM-103-01-G-D-RA features full gold plating; TMM-103-01-S-D-RA uses tin-plated posts with gold mating contacts; TMMH-103-01-F-D-RA is a low-profile variant with the shortest post length. All three maintain electrical compatibility and RoHS3 compliance.

Q: Does the change from Polyamide to Liquid Crystal Polymer (LCP) insulation material affect compatibility?

A: LCP insulation in the Samtec variants provides improved thermal and mechanical properties compared to glass-filled polyamide. This change is a material upgrade that does not compromise electrical or mechanical compatibility. LCP offers better dimensional stability and higher temperature performance.

Q: Are there current rating differences between the original and substitute parts?

A: The original 86453-506 is rated at 2A (AC/DC). The TMM-103-01-G-D-RA and TMM-103-01-S-D-RA substitutes are rated at 3.2A per contact, providing higher current capacity. The TMMH-103-01-F-D-RA does not specify a current rating in available documentation. For applications requiring the original 2A specification, all substitutes exceed this requirement.

Q: What is the significance of RoHS3 compliance on the substitute parts?

A: RoHS3 compliance indicates conformance to current European Union Restriction of Hazardous Substances regulations. The original 86453-506 is non-compliant, which may restrict its use in new designs destined for EU markets or applications subject to RoHS requirements. All three Samtec substitutes are RoHS3 compliant, supporting modern supply chain and regulatory requirements.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For maximum reliability and corrosion resistance, TMM-103-01-G-D-RA is recommended. For cost optimization without sacrificing performance, TMM-103-01-S-D-RA is appropriate. For space-constrained designs, TMMH-103-01-F-D-RA provides the low-profile advantage. All three are active products with established availability.
