Amphenol ICC 55510-034 34-Position 0.079" Rectangular Connector Equivalent & Substitute Parts
Part Overview
The Amphenol ICC 55510-034 is a 34-position receptacle connector with 0.079" (2.00mm) pitch designed for surface mount board-to-board applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility (34 positions, 2.00mm pitch, 2A current rating minimum) and mechanical interchangeability (surface mount, push-pull fastening, similar insulation height).

Engineering Selection Recommendations
Primary Substitute - Amphenol ICC 55510-034LF: Direct manufacturer upgrade from the obsolete 55510-034. Identical electrical and mechanical specifications with RoHS compliance and active product status. Recommended for direct replacement in new designs and production restarts.
Samtec MMS-117 Series (MMS-117-02-F-DV variants): Active production alternatives with enhanced current rating (3.9A per contact) and full operating temperature range (-55°C to 125°C). Available in multiple packaging configurations (tube, tape & reel). RoHS3 compliant. Suitable for applications requiring higher current capacity or automated assembly (pick and place variants available).
Molex 0873813418: Active alternative from established connector manufacturer. Meets core electrical requirements with board guide feature. Operating temperature limited to -55°C to 105°C and current rating of 1.9A. Suitable for applications not requiring full 125°C upper temperature limit.
3M 150234-2020-RB: Active alternative with highest voltage rating (500VDC). Current rating of 1A limits suitability to lower-power applications. Operating temperature range -55°C to 105°C. Tray packaging suitable for manual assembly workflows.
Compliance Considerations: The original 55510-034 is RoHS non-compliant. All recommended substitutes (55510-034LF, Samtec MMS-117 series, Molex 0873813418, 3M 150234-2020-RB) are RoHS compliant or RoHS3 compliant, meeting current regulatory requirements for new designs and production.
Frequently Asked Questions (FAQ)
Q: Can MMS-117-02-F-DV-K replace 55510-034 directly? A: Yes. Both connectors share identical 34-position, 2.00mm pitch, surface mount, push-pull configuration with gold mating contacts. The Samtec part offers higher current capacity (3.9A per contact vs. 2A) and active product status. Mechanical and electrical compatibility is confirmed.
Q: What is the difference between MMS-117-02-F-DV-K and MMS-117-02-F-DV-K-TR? A: Both parts are electrically and mechanically identical. The primary difference is packaging: MMS-117-02-F-DV-K is supplied in tube format, while MMS-117-02-F-DV-K-TR is supplied in tape & reel format. Tape & reel packaging is optimized for automated pick-and-place assembly; tube packaging is suitable for manual assembly or lower-volume applications.
Q: Is 55510-034LF a true equivalent to 55510-034? A: Yes. The 55510-034LF is the active production replacement from Amphenol ICC. Specifications are identical to the obsolete 55510-034 except for RoHS compliance status (LF designation indicates lead-free/RoHS compliant). This is the recommended direct substitute.
Q: Can I use the 3M 150234-2020-RB if my application requires 2A current? A: No. The 3M part is rated for 1A maximum current, which is below the 2A requirement of the original 55510-034. This part is suitable only for applications with lower current demands.
Q: What is the significance of the "A-K" suffix in MMS-117-02-F-DV-A-K? A: The "A-K" suffix indicates board guide and pick-and-place features. These variants are optimized for automated assembly processes. Electrically and mechanically, they are equivalent to other MMS-117-02-F-DV variants.
Q: Does operating temperature range affect substitution eligibility? A: Yes, if your application requires the full -55°C to 125°C range. The Molex 0873813418 and 3M 150234-2020-RB are limited to -55°C to 105°C. The Amphenol 55510-034LF and Samtec MMS-117 series support the full -55°C to 125°C range and are preferred for high-temperature applications.
Q: Are all substitute parts in stock? A: Inventory levels vary by part number and supplier. Amphenol 55510-034LF (1011 pcs), Samtec MMS-117-02-F-DV-K (1098 pcs), and Samtec MMS-117-02-F-DV-A-K-TR (1059 pcs) show highest availability. Confirm current stock status with your supplier before finalizing procurement.
