Substitute Part Grouping Explanation

The FX8C-140P-SV2(93) has one identified parametric equivalent: FX8C-140P-SV2(92). Substitution eligibility is determined by the following critical parameters that must remain identical:

• Number of Positions: 140
• Pitch: 0.024" (0.60mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Height Above Board: 0.254" (6.45mm)
• Mated Stacking Heights: 7mm, 12mm
• Features: Board Guide
• Series: FunctionMax™ FX8C
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part maintains full electrical and mechanical compatibility with the main part number, differing only in internal design revision or manufacturing batch designation indicated by the suffix variation (93 vs. 92).

Parameter Comparison

Engineering Selection Recommendations

Both the FX8C-140P-SV2(93) and FX8C-140P-SV2(92) are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences. Both parts maintain full RoHS compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and long-term storage without moisture sensitivity constraints. The FX8C-140P-SV2(92) currently has higher inventory availability (1612 pcs vs. 902 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can FX8C-140P-SV2(92) be used as a direct replacement for FX8C-140P-SV2(93)?

A: Yes. Both parts are parametrically equivalent with identical electrical and mechanical characteristics, including position count, pitch, mounting type, contact finish, and board height. The suffix variation indicates internal design revision or batch designation only.

Q: Are there any compatibility concerns when substituting between these part numbers?

A: No. The parts share identical specifications for all critical parameters: 140 positions, 0.024" pitch, 2-row configuration, surface mount mounting, gold contact finish, and board guide features. PCB footprints, mating interfaces, and assembly processes are identical.

Q: What is the significance of the suffix numbers (93 vs. 92)?

A: The suffix indicates internal design revision or manufacturing batch designation. This does not affect electrical performance, mechanical fit, or functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both FX8C-140P-SV2(93) and FX8C-140P-SV2(92) are RoHS compliant with MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Q: What are the mated stacking height options?

A: Both parts support mated stacking heights of 7mm and 12mm, allowing flexibility in connector stack configurations for multi-layer interconnect designs.
