Amphenol ICC 51940-113 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51940-113 is a 60-position blade power receptacle connector from the PwrBlade® series, designed for through-hole PCB mounting applications. This connector features female sockets and blade sockets with a 0.100" (2.54mm) pitch, supporting 52 signal and 8 power contacts across 4 rows.

The 51940-113 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51940-113 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle, Female Sockets and Blade Sockets)
• Number of positions (60)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (4)
• Contact layout (52 Signal, 8 Power)
• Mounting method (Through Hole)
• Termination style (Press-Fit, Solder)
• Contact finish specification (Gold or Gold, GXT™)
• Operating temperature range (-20°C ~ 105°C)
• Flammability rating (UL94 V-0)

The 51940-113LF meets all these criteria and qualifies as a direct substitute. Differences in product status, packaging format, and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 51940-113LF is the direct substitute for the obsolete 51940-113. Both parts are electrically and mechanically identical across all functional parameters.

Selection between these parts should be based on the following factors:

• Product Status: The 51940-113LF is active and maintains current manufacturing support, while the 51940-113 is obsolete. For new designs and ongoing production, the 51940-113LF is the appropriate choice.

• Compliance: The 51940-113LF is RoHS Compliant and REACH Affected, meeting current environmental and regulatory requirements. The 51940-113 is RoHS non-compliant. Applications subject to RoHS or REACH regulations require the 51940-113LF.

• Packaging: The 51940-113LF is supplied in Tray packaging, which may differ from the original part's packaging format. Verify packaging compatibility with assembly and handling processes.

• Inventory Availability: The 51940-113LF has higher current inventory (1050 Pcs) compared to the 51940-113 (706 Pcs), supporting longer-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Are the 51940-113 and 51940-113LF electrically interchangeable?

A: Yes. Both parts share identical electrical specifications, including connector type, position count, pitch, contact layout, contact finish, and operating temperature range. They are direct electrical equivalents.

Q: Are the 51940-113 and 51940-113LF mechanically interchangeable?

A: Yes. Both parts have identical mechanical specifications, including mounting type (Through Hole), termination method (Press-Fit, Solder), physical dimensions, and row configuration. They are direct mechanical equivalents.

Q: What is the difference between the 51940-113 and 51940-113LF?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. Compliant), REACH status (not listed vs. Affected), and packaging format (Bulk vs. Tray). Electrical and mechanical specifications are identical.

Q: Can I use the 51940-113LF as a replacement for the 51940-113 in existing designs?

A: Yes. The 51940-113LF is a direct substitute and can be used in place of the 51940-113 without design modifications. Verify that your application and supply chain requirements are compatible with the 51940-113LF's active status and RoHS compliance.

Q: Does the packaging difference affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. However, Tray packaging may require different handling, storage, and assembly line integration compared to the original packaging. Verify compatibility with your assembly process and material handling systems.

Q: Are there any certifications or compliance differences I should consider?

A: The 51940-113LF is RoHS Compliant and REACH Affected, while the 51940-113 is RoHS non-compliant. Both parts maintain UL94 V-0 flammability rating and identical operating specifications. Applications subject to RoHS or REACH regulations must use the 51940-113LF.
