Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51940-076 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Receptacle, Female Blade Sockets; Blade Power)
• Number of positions (3)
• Pitch specification (0.300" / 7.62mm)
• Mounting method (Through Hole)
• Termination type (Press-Fit)
• Contact layout (3 Power)
• Physical features (Board Lock, Guide Pin)
• Contact finish and thickness (Gold or Gold, GXT™; 30.0µin)
• Color (Black)
• Flammability rating (UL94 V-0)
• Operating temperature range (-20°C ~ 105°C)
• Moisture sensitivity level (MSL 1)

The substitute part 51940-076LF meets all these criteria and is manufactured by the same supplier within the same PwrBlade® series. The primary distinction is product status and compliance certification.

Parameter Comparison

• RoHS compliance certification (51940-076LF) versus non-compliance (51940-076)
• REACH affected status on the substitute part indicates compliance with current regulatory frameworks
• Tray packaging on the substitute part provides improved handling and storage compared to bulk packaging

For applications requiring the 51940-076, the 51940-076LF provides direct functional equivalence with enhanced compliance posture. No electrical or mechanical redesign is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 51940-076LF be used as a direct replacement for the 51940-076?

A: Yes. The 51940-076LF is electrically and mechanically equivalent to the 51940-076. All critical parameters including connector type, position count, pitch, mounting method, termination type, contact finish, and operating specifications are identical.

Q: What is the difference between the two parts?

A: The primary differences are product status, compliance certifications, and packaging. The 51940-076LF is an active product with RoHS compliance and REACH compliance status, while the 51940-076 is obsolete and RoHS non-compliant. The substitute part is supplied in tray packaging versus bulk.

Q: Are there any compatibility concerns when substituting the 51940-076LF for the 51940-076?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable. PCB footprints, mounting hole patterns, and contact positions are identical.

Q: Does the packaging difference affect performance or installation?

A: No. Packaging format does not affect connector performance or installation. Tray packaging provides improved component protection during storage and handling compared to bulk packaging.

Q: What certifications apply to each part?

A: Both parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. The 51940-076LF additionally carries RoHS compliance and REACH compliance certifications, which the obsolete 51940-076 does not possess.
