Amphenol ICC 51627-002 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51627-002 is a right-angle, low-frequency receptacle power blade connector designed for backplane applications. This part is classified as obsolete and is no longer in active production. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for system redesign, maintenance, and procurement planning. The 51627-002LF serves as the direct successor, offering identical mechanical and electrical performance while maintaining active product status and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

The 51627-002LF is classified as a direct manufacturer substitute for the 51627-002. Substitution eligibility is determined by the following critical parameters:

• Connector Type & Function: Both parts are receptacle connectors with female sockets and blade sockets, designed for power blade applications
• Mounting Configuration: Both feature board edge, through-hole, right-angle mounting
• Electrical Performance: Identical current rating (70A) and contact layout (24 Signal, 2 Power)
• Physical Dimensions: Same pitch (0.100" / 2.54mm), 26 positions, 4 rows
• Termination Method: Both use solder termination
• Environmental Ratings: Identical operating temperature range (-55°C ~ 125°C) and MSL classification (1 - Unlimited)
• Material & Finish: Same contact finish (Gold, 30.0µin thickness) and color (Black)

The primary distinction is product status: the 51627-002LF is active and RoHS compliant, whereas the 51627-002 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 51627-002LF is the direct functional equivalent and recommended substitute for the obsolete 51627-002. Selection should be based on the following criteria:

Product Status Consideration: The 51627-002 is obsolete and no longer manufactured. The 51627-002LF maintains identical mechanical and electrical specifications while offering active product status with ongoing manufacturing support and availability.

Compliance Requirements: If RoHS compliance is mandated by system specifications or regulatory requirements, the 51627-002LF is the only viable option. The original 51627-002 is RoHS non-compliant and unsuitable for applications requiring RoHS certification.

Electrical & Mechanical Compatibility: Both connectors share identical electrical ratings (70A current capacity), physical dimensions (26 positions, 0.100" pitch, 4 rows), mounting configuration (board edge, through-hole, right-angle), and contact layout (24 Signal, 2 Power). Direct substitution is mechanically and electrically feasible without design modification.

Environmental Performance: Both parts operate across the same temperature range (-55°C ~ 125°C) and share identical moisture sensitivity classification (MSL 1 - Unlimited), ensuring equivalent environmental performance.

Packaging & Procurement: The 51627-002LF is supplied in tray packaging with 883 units currently in stock, providing reliable procurement availability compared to the discontinued 51627-002.

Frequently Asked Questions (FAQ)

Q: Can the 51627-002LF be used as a direct replacement for the 51627-002 without PCB redesign?

A: Yes. Both connectors feature identical mechanical dimensions, pitch (0.100" / 2.54mm), number of positions (26), row configuration (4 rows), and mounting type (board edge, through-hole, right-angle). No PCB layout modification is required.

Q: What is the primary reason for substitution?

A: The 51627-002 is obsolete and no longer manufactured. The 51627-002LF is the active equivalent offering identical performance with current manufacturing support and availability.

Q: Are there electrical performance differences between the two parts?

A: No. Both connectors share identical electrical specifications: 70A current rating, 24 Signal and 2 Power contact layout, gold-plated contacts, and -55°C ~ 125°C operating temperature range.

Q: Does the 51627-002LF meet RoHS compliance requirements?

A: Yes. The 51627-002LF is RoHS compliant. The original 51627-002 is RoHS non-compliant. If RoHS certification is required, the 51627-002LF is mandatory.

Q: Are there packaging differences?

A: The 51627-002LF is supplied in tray packaging. Original packaging specifications for the 51627-002 are not provided in the technical data.

Q: What is the MSL rating for both parts?

A: Both the 51627-002 and 51627-002LF carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Is the 51627-002LF part of a product series?

A: Yes. The 51627-002LF is designated as part of the PwrBlade® series, Amphenol ICC's power blade connector line.
