Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51710-017 is determined by strict equivalence across the following critical parameters:

• Connector type, style, and series (Header, Male Pins and Blades; Blade Power; PwrBlade®)
• Position count and row configuration (40 positions, 4 rows)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination capability (Press-Fit, Solder)
• Contact layout (32 Signal, 8 Power)
• Physical features (Mating Guide, Black color)
• Electrical and thermal ratings (UL94 V-0, -20°C ~ 105°C)

The substitute part 51710-017LF maintains identical electrical, mechanical, and dimensional specifications while differing in product status (Active vs. Obsolete) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 51710-017LF is the direct active equivalent of the obsolete 51710-017. Both parts are manufactured by Amphenol ICC within the PwrBlade® series and maintain identical mechanical, electrical, and thermal specifications. The primary distinction is product lifecycle status: the 51710-017 is obsolete while the 51710-017LF remains in active production.

For new designs or ongoing production requiring compliance with modern environmental standards, the 51710-017LF is the appropriate selection due to its RoHS Compliant status. For legacy system maintenance where RoHS non-compliant components are acceptable, the 51710-017 remains functionally equivalent where inventory permits.

Both parts are supplied with MSL 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 51710-017LF be used as a direct replacement for the 51710-017?

A: Yes. The 51710-017LF is electrically and mechanically identical to the 51710-017. Both connectors feature 40 positions in a 4-row configuration, 0.100" pitch, through-hole mounting, and identical contact specifications. The primary difference is product status and RoHS compliance.

Q: What is the significance of the "LF" suffix in the part number 51710-017LF?

A: The "LF" designation indicates Lead-Free construction, which correlates with RoHS Compliance. This part meets current environmental and regulatory requirements for lead-free solder compatibility.

Q: Are there packaging differences between these parts?

A: The 51710-017 packaging is not specified in the technical data. The 51710-017LF is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the contact layout for these connectors?

A: Both connectors feature a 32 Signal, 8 Power contact layout within the 40-position configuration, supporting mixed-signal and power distribution applications.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate within the -20°C to 105°C temperature range and carry UL94 V-0 flammability rating. Confirm suitability for your specific thermal environment within these specified limits.

Q: What is the moisture sensitivity classification?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient.
