Amphenol ICC 51915-049 Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51915-049 is a 42-position receptacle connector featuring female sockets and blade sockets, designed for board edge, through-hole, right-angle mounting in blade power applications. This connector is part of the PwrBlade® series and provides a contact layout of 32 signal and 10 power positions with gold-plated contacts and board lock features.

The 51915-049 is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair, and continued operation where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 51915-049 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Connector type (receptacle with female sockets and blade sockets)
• Position count (42 total positions, 30 loaded)
• Pitch and row configuration (0.100" pitch, 4 rows)
• Mounting method (board edge, through hole, right angle)
• Contact layout (32 signal, 10 power)
• Contact finish and thickness (gold plating, 30.0µin)
• Flammability and temperature ratings
• Physical color and features (black, board lock, guide pin)

The 51915-049LF meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 51915-049LF is the direct substitute for the obsolete 51915-049. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the two parts is product status and compliance:

• The 51915-049 is obsolete and non-RoHS compliant
• The 51915-049LF is active and RoHS compliant

For new designs or systems requiring RoHS compliance, the 51915-049LF is the appropriate selection. For legacy system support where the original 51915-049 is no longer available, the 51915-049LF provides full functional equivalence with improved compliance status. The packaging difference (bulk versus tray) does not affect electrical or mechanical performance and is a logistics consideration only.

Frequently Asked Questions (FAQ)

Q: Can the 51915-049LF be used as a direct replacement for the 51915-049?

A: Yes. The 51915-049LF is electrically and mechanically identical to the 51915-049 across all specified parameters, including connector type, position count, pitch, mounting configuration, contact layout, and operating characteristics.

Q: What is the difference between the 51915-049 and 51915-049LF?

A: The primary differences are product status, RoHS compliance, and packaging. The 51915-049 is obsolete and non-RoHS compliant, while the 51915-049LF is active and RoHS compliant. The 51915-049LF is supplied in tray packaging, whereas the 51915-049 is supplied in bulk packaging.

Q: Are there any compatibility concerns when substituting the 51915-049LF for the 51915-049?

A: No compatibility concerns exist. Both connectors maintain identical specifications for connector type, solder termination, contact finish, flammability rating, and operating temperature range. Board-level integration and mating connector requirements remain unchanged.

Q: Does the packaging difference between bulk and tray affect performance?

A: No. Packaging is a logistics and handling consideration only and does not affect electrical performance, mechanical fit, or functional characteristics of the connector.

Q: Why is the 51915-049 classified as obsolete?

A: The 51915-049 has been superseded by the 51915-049LF, which offers improved compliance status (RoHS compliant) while maintaining full functional equivalence. The LF variant is the current active part number for this connector configuration.
