Substitute Part Grouping Explanation

Substitution of the 51760-10402002AA is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets and blade sockets
• Position Count & Layout: 26 positions with 20 signal and 6 power contact arrangement
• Pitch & Spacing: 0.100" (2.54mm) pitch with 4-row configuration
• Mounting & Termination: Board edge, through-hole, right-angle mounting with solder termination
• Environmental & Compliance Ratings: UL94 V-0 flammability, -20°C to 105°C operating range
• Series Compatibility: PwrBlade® series designation

The substitute part 51760-10402002AALF maintains identical electrical and mechanical specifications while offering active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 51760-10402002AALF is the direct functional equivalent of the obsolete 51760-10402002AA. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part is obsolete, while the substitute maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance: The substitute part achieves RoHS compliance, whereas the main part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements.

Electrical & Mechanical Equivalence: Both parts maintain identical specifications across connector type, position count, pitch, mounting configuration, contact layout, and environmental ratings. No functional differences exist between the two parts.

Packaging Consideration: The substitute is supplied in tray packaging, whereas the main part uses bulk packaging. This packaging difference does not affect electrical or mechanical performance.

For new designs or component replacement in existing systems, the 51760-10402002AALF should be specified to ensure compliance with current regulatory standards and sustained component availability.

Frequently Asked Questions (FAQ)

Q: Are the 51760-10402002AA and 51760-10402002AALF electrically identical?

A: Yes. Both parts maintain identical electrical specifications including contact layout (20 signal, 6 power), contact finish (Gold or Gold, GXT™), contact finish thickness (30.0µin), and operating temperature range (-20°C ~ 105°C).

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete vs. active) and RoHS compliance. The substitute part is RoHS compliant and maintains active production status. Packaging also differs: bulk for the main part and tray for the substitute.

Q: Can the 51760-10402002AALF be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical mechanical and electrical specifications, including mounting type (board edge, through-hole, right-angle), pitch (0.100"), row configuration (4 rows), and termination method (solder). Direct substitution is mechanically and electrically compatible.

Q: Does the tray packaging of the substitute part affect connector performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tray packaging is a logistics consideration only and does not impact connector functionality or reliability.

Q: Why is RoHS compliance important for this connector?

A: RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs) in the component. For applications subject to RoHS regulations or customer requirements, the compliant substitute part is necessary.

Q: Are there any thermal or environmental performance differences?

A: No. Both parts maintain identical operating temperature range (-20°C ~ 105°C), moisture sensitivity level (MSL 1), and material flammability rating (UL94 V-0).
